Highlights of GAO-09-288, a report to congressional committees. 

Why GAO Did This Study: 

The Future Combat System (FCS) program is the centerpiece of the Army’s 
effort to transition to a lighter, more agile, and more capable combat 
force. By law, GAO is to report annually on the FCS program. Also, law 
requires the Department of Defense (DOD) to hold a milestone review of 
the FCS program, now planned for 2009. This report addresses (1) what 
knowledge will likely be available in key areas for the review, and (2) 
the challenges that lie ahead following the review. To meet these 
objectives, GAO reviewed key documents, performed analysis, attended 
demonstrations and design reviews, and interviewed DOD officials. 

What GAO Found: 

The Army will be challenged to demonstrate the knowledge needed to 
warrant an unqualified commitment to the FCS program at the 2009 
milestone review. While the Army has made progress, knowledge 
deficiencies remain in key areas. Specifically, all critical 
technologies are not currently at a minimum acceptable level of 
maturity. Neither has it been demonstrated that emerging FCS system 
designs can meet specific requirements or mitigate associated technical 
risks. Actual demonstrations of FCS hardware and software—versus 
modeling and simulation results—have been limited, with only small 
scale warfighting concepts and limited prototypes demonstrated. Network 
performance is also largely unproven. These deficiencies do not 
necessarily represent problems that could have been avoided; rather, 
they reflect the actual immaturity of the program. Finally, there is an 
existing tension between program costs and available funds that seems 
only likely to worsen, as FCS costs are likely to increase at the same 
time as competition for funds intensifies between near- and far-term 
needs in DOD and between DOD and other federal agencies. 

DOD could have at least three programmatic directions to consider for 
shaping investments in future capabilities, each of which presents 
challenges. First, the current FCS acquisition strategy is unlikely to 
be executed within the current $159 billion cost estimate and calls for 
significant production commitments before designs are demonstrated. To 
date, FCS has spent about 60 percent of its development funds, even 
though the most expensive activities remain to be done before the 
production decision. In February 2010, Congress will be asked to begin 
advancing procurement funds for FCS core systems before most prototype 
deliveries, critical design review, and key system tests have taken 
place. By the 2013 production decision, Congress will have been asked 
for over $50 billion in funding for FCS. Second, the program to spin 
out early FCS capabilities to current forces operates on an aggressive 
schedule centered on a 2009 demonstration that will employ some 
surrogate systems and preliminary designs instead of fully developed 
items, with little time for evaluation of results. Third, the Army is 
currently considering an incremental FCS strategy—this is to develop 
and field capabilities in stages versus in one step. Such an approach 
is generally preferable, but would present decision makers with a third 
major change in FCS strategy to consider anew. While details are yet 
unavailable, it is important that each increment be justified by itself 
and not be dependent on future increments. 

What GAO Recommends: 

GAO suggests Congress consider not approving full funds for the program 
until several conditions are met, such as preparation of a complete 
budget for any program emerging from the milestone review. GAO also 
recommends the Secretary of Defense, among other things, ensure: the 
program that emerges conforms to current defense acquisition policy, 
such as technology maturity; any spin out approach is based on fully 
tested results; and any incremental strategy involves free-standing, 
justifiable increments. DOD concurred with GAO’s recommendations.

Congressional Committees: 

The Future Combat System (FCS) program--which comprises 14 integrated 
weapon systems and an advanced information network needed for a brigade 
combat team--is the centerpiece of the Army's efforts to transition to 
a lighter, more agile, and more capable combat force and according to 
the Army, the greatest technology and integration challenge it has ever 
undertaken. The Army seeks to develop and then integrate dozens of new 
technologies in the FCS program and ultimately create a force in which 
people, platforms, weapons and sensors are linked seamlessly together 
in a system-of-systems. 

The Army started the FCS program in May 2003 without having fully 
defined the individual systems, their functions, or how they would 
interact. The Army moved ahead without determining whether the concept 
could be successfully developed with existing resources--without proven 
technologies, a stable design, and available funding and time. The Army 
currently projects the program will cost $159 billion, although the 
Army has indicated that cost increases are likely. The program is also 
using a unique partner-like arrangement with a lead system integrator 
(LSI), the Boeing Company, to manage and produce the FCS. For these and 
other reasons, the program is recognized as being high risk and in need 
of special oversight. Accordingly, in 2006, Congress mandated that the 
Department of Defense (DOD) hold a milestone review (also called go/no- 
go review) following the FCS preliminary design review, which is now 
tentatively scheduled for May 2009.[Footnote 1] Congress directed that 
the review include an assessment of whether (1) the needs are valid and 
can best be met with the FCS concept, (2) the FCS program can be 
developed and produced within existing resources, and (3) the program 
should continue as currently structured, be restructured, or be 
terminated. Congress required the Secretary of Defense to review and 
report on specific aspects of the program, including the maturity of 
critical technologies, program risks, demonstrations of the FCS concept 
and software, and a cost estimate and affordability assessment. 

Given the cost, scope, and technical challenges, section 211 of the 
National Defense Authorization Act for Fiscal Year 2006 requires GAO to 
report annually on the FCS program.[Footnote 2] The objectives of this 
report are to determine (1) to what extent knowledge will likely be 
available to DOD, the Army, and the Congress in the key areas of 
technology, design, demonstrations, network performance, and cost and 
affordability to support the 2009 milestone review and (2) the 
challenges that a program (or programs) to furnish the Army with future 
capabilities will face following the milestone review. 

In conducting our work, we reviewed documents pertaining to the FCS 
program, including the Operational Requirements Document, the 
Acquisition Strategy Report, technology assessments, and modeling and 
simulation results; attended meetings at which DOD and Army officials 
reviewed program progress; and held discussions with key DOD and Army 
officials on various aspects of the program. Officials from DOD and the 
Army have provided us access to sufficient information to make informed 
judgments on the matters in this report. In addition, we drew from our 
body of past work on weapon system acquisition practices and conducted 
our own analyses in key areas such as cost and technology. We conducted 
this performance audit from March 2008 to March 2009 in accordance with 
generally accepted government auditing standards. Those standards 
require that we plan and perform the audit to obtain sufficient, 
appropriate evidence to provide a reasonable basis for our findings and 
conclusions based on our audit objectives. We believe that the evidence 
obtained provides a reasonable basis for our findings and conclusions 
based on our audit objectives. Appendix I further discusses our scope 
and methodology. 

Background: 

The FCS concept is designed to be part of the Army's Future Force, 
which is intended to transform the Army into a more rapidly deployable 
and responsive force that differs substantially from the large division-
centric structure of the past. The Future Force is to be offensively 
oriented and will employ revolutionary concepts of operations, enabled 
by new technology. The Army envisions a new way of fighting that 
depends on networking the force, which involves linking people, 
platforms, weapons, and sensors seamlessly together in a system-of-
systems. If successful, the FCS system-of-systems concept would 
integrate individual capabilities of weapons and platforms, thus 
facilitating interoperability and open system designs. This concept 
would represent a significant improvement over the traditional approach 
of building superior individual weapons that must be retrofitted and 
netted together after the fact. 

The Army is reorganizing its current forces into modular brigade combat 
teams, each of which is expected to be highly survivable and the most 
lethal brigade-sized unit the Army has ever fielded. The Army expects 
FCS-equipped brigade combat teams to provide significant warfighting 
capabilities to DOD's overall joint military operations. The Army is 
implementing its transformation plans at a time when current U.S. 
ground forces continue to play a critical role in ongoing conflicts in 
Iraq and Afghanistan. The Army has instituted plans to spin out 
selected FCS technologies and systems to current Army forces throughout 
the program's system development and demonstration phase. 

FCS is to be composed of advanced, networked air and ground-based 
combat and maneuver sustainment systems, unmanned ground and air 
vehicles, and unattended sensors and munitions. (See figure 1.) The 
soldier is the centerpiece of the system-of-systems architecture and is 
networked with 14 FCS core systems and numerous other enabling systems 
referred to as complementary programs. FCS is expected to be networked 
via a command, control, communications, computers, intelligence, 
surveillance, and reconnaissance architecture, including networked 
communications, network operations, sensors, battle command systems, 
training, and both manned and unmanned reconnaissance and surveillance 
capabilities that will enable improved situational understanding and 
operations at a level of synchronization heretofore unachievable. With 
that, FCS brigade combat teams are expected to be able to execute a new 
tactical paradigm based on the quality of firsts--the capability to see 
first, understand first, act first, and finish decisively. 
Fundamentally, the FCS concept is to replace mass with superior 
information--allowing the soldier to see and hit the enemy first rather 
that to rely on heavy armor to withstand a hit.

The Army is using a management approach for FCS that centers on an LSI 
to provide significant management services to help the Army define and 
develop FCS and reach across traditional Army mission areas. Because of 
its partner-like relationship with the Army, the LSI's responsibilities 
include requirements development, design, and selection of major system 
and subsystem contractors. The team of Boeing and its subcontractor, 
Science Applications International Corporation, is the LSI for the FCS 
system development and demonstration phase of acquisition, which is 
expected to extend until 2017. The FCS LSI is expected to act on behalf 
of the Army to optimize the FCS capability, maximize competition, 
ensure interoperability, and maintain commonality in order to reduce 
life-cycle costs, and for overall integration of the information 
network. Boeing also acts as an FCS supplier in that it is responsible 
for developing two important software subsystems. Army officials have 
stated they did not believe the Army had the resources or flexibility 
to use its traditional acquisition process to field a program as 
complex as FCS under the aggressive timeline established by the then- 
Army Chief of Staff. The Army will maintain oversight and final 
approval of the LSI's subcontracting and competition plans. 

Legislative Requirements for FCS Milestone Review: 

The John Warner National Defense Authorization Act for Fiscal Year 2007 
mandated that the Secretary of Defense carry out a Defense Acquisition 
Board milestone review of FCS not later than 120 days after the system- 
of-systems preliminary design review, which is now tentatively 
scheduled for May 2009.[Footnote 3] The legislation is consistent with 
our 2006 report on FCS wherein we recommended that the Secretary of 
Defense establish a Defense Acquisition Board milestone review 
following the Army's design review.[Footnote 4] Moreover, we 
recommended that this should be a go/no-go review of the FCS program 
based on its ability to meet knowledge markers consistent with DOD 
acquisition policy and best practices and demonstrate the availability 
of funds necessary to meet program costs. According to the law, DOD's 
2009 milestone review of FCS should include an assessment for each of 
the following: 

(1) whether the warfighter's needs are valid and can be best met with 
the concept of the program; (2) whether the concept of the program can 
be developed and produced within existing resources; and (3) whether 
the program should: 

(a) continue as currently structured; 
(b) continue in restructured form; or, 
(c) be terminated. 

Furthermore, the Congress stipulated that the Secretary make specific 
determinations when making the assessment concerning the future course 
of the FCS program. The original language contained six criteria the 
Secretary was to use when answering the three assessment questions. In 
our 2008 report on the FCS program, we recommended that the Secretary 
establish objective and quantitative criteria that the FCS program will 
have to meet in order to justify its continuation and gain approval for 
the remainder of the acquisition strategy.[Footnote 5] Subsequently, 
the Duncan Hunter National Defense Authorization Act for Fiscal Year 
2009 amended and expanded the existing requirements and added four new 
criteria.[Footnote 6] These changes expand the scope of supporting 
information the Congress mandated to be included with the DOD milestone 
review report. 

For example, the 2009 Act requires the Secretary, when making his 
assessment of the program, to determine whether actual demonstrations, 
rather than simulations, have shown that the software for the program 
is on path to achieve threshold requirements on cost and schedule. 
Appendix III contains the legislative requirements for the 2009 
milestone review. For the purposes of our analysis, we aggregated the 
congressional criteria into four key areas: technology maturity, 
requirements/design, demonstrations (FCS concept and network), and 
cost. 

In 2008, we found that the progress made by FCS, in terms of knowledge 
gained, was commensurate with a program in early development but was 
well short of a program halfway through its development schedule and 
its budget. In view of these findings, we recommended, in part, that 
the Secretary of Defense establish criteria that the FCS must meet in 
the 2009 milestone review in order to justify continuation along with 
identifying viable alternatives to FCS.[Footnote 7] 

In response to this recommendation, and to facilitate the Secretary's 
assessment of the status of FCS and to decide the program's future, the 
Under Secretary of Defense for Acquisitions, Technology and Logistics 
issued an acquisition decision memorandum in August 2008 to the 
Secretary of the Army outlining the information the Army must provide. 
The Under Secretary established criteria for supporting information in 
five program areas: program execution, unmanned systems, manned ground 
vehicles, network, and test/experimentation/demonstration. The Under 
Secretary has established specific criteria within each of the five 
areas, as shown in Appendix IV. For example, in the area of program 
execution, the Army must demonstrate that the FCS, Joint Tactical Radio 
System (JTRS), and Warfighter Information Network Tactical (WIN-T) 
programs' development, build, and test schedules are aligned and 
executable. The Under Secretary's memorandum also instructed the Army 
to mature its acquisition approach to deliver initial increments of FCS 
capability to infantry brigade combat teams rather than the originally 
planned heavy brigades. For the FCS core program, the Under Secretary 
stated that the Army shall pursue an incremental or block approach to 
acquiring FCS capability. 

Along with the mandated 2009 milestone review of FCS, the Congress has 
required the DOD and the Army to perform analyses and report separately 
on two core systems of the FCS system-of-systems.[Footnote 8] 
Specifically, the Assistant Secretary of Defense for Networks and 
Information Integration is to report on an analysis of the FCS 
communications network and software. This report, due not later than 
September 30, 2009, will include assessments of issues such as network 
vulnerability to enemy attack, electronic warfare, jamming, and adverse 
weather. (See appendix V.) 

Significant Knowledge Gaps Persist in Key Areas: 

Compared with the criteria to be used for the milestone review, the FCS 
program has significant knowledge gaps. Specifically, the program has 
yet to show that critical technologies are mature, design issues have 
been resolved, requirements and resources are matched, performance has 
been demonstrated versus simulated, and costs are affordable. The Army 
will be challenged to convincingly demonstrate the knowledge necessary 
to warrant an unqualified commitment to FCS at the 2009 milestone 
review. Four of the critical technologies have not yet achieved 
minimally acceptable maturity levels despite being in development for 
at least 6 years. The schedule to complete the remaining preliminary 
design reviews is aggressive, and it seems clear from the results of 
the initial system-level preliminary design reviews that numerous 
performance trade-offs will be needed to close gaps between FCS 
requirements and designs. Actual demonstrations (versus modeling and 
simulation) of the FCS concept, including its critical survivability 
aspects, have been limited to date; demonstrated network performance is 
particularly limited with many key questions yet to be answered. 
Finally, FCS costs appear likely to increase again at a time when 
available funds may decline. 

Major Risks Remain in the Maturation of FCS Technologies: 

In making the assessment of whether the FCS program should continue, 
DOD is required by congressional direction to make a determination of 
whether each critical technology for the program is at least TRL 6. The 
Army has struggled to attain this level of maturity, despite being a 
lower standard than preferred by DOD policy and falling short of best 
practices. At TRL 6, a representative model or prototype exists and is 
tested in a relevant environment--a maturity level well beyond TRL 5 
where the technology demonstrates functionality in a laboratory 
environment but does not have the physical form or fit of the finished 
product. Appendix VI contains a complete listing and description of 
TRLs. Army technology officials stated the purpose of TRL 6 
demonstrations is to build confidence the concept is technically 
feasible, and TRL 6 actually means extensive testing remains before TRL 
7 can be achieved. Maturing technologies to TRL 7 (prototype possessing 
the form, fit, and function of the finished product that is 
demonstrated in a realistic environment) prior to starting product 
development is a best practice and a DOD policy preference.[Footnote 9] 
Against these standards, all FCS technologies should have achieved TRL 
7 as the program proceeded into the system development and 
demonstration phase in May 2003. Even if the Army does demonstrate TRL 
6 in 2009, extending technology development this late into the 
acquisition process puts FCS at risk for experiencing problems that may 
require large amounts of time and money to fix. 

The Army anticipates that all the critical technologies will reach TRL 
6 by the milestone review, but this projection deserves closer 
examination and perspective. The Army may be unable to demonstrate 
technology maturity as quickly as it plans. Based on Army assessments 
from January 2009, three of the 44 FCS critical technologies were rated 
TRL 7 and 37 were rated TRL 6. The remaining technologies are expected 
to complete TRL 6 demonstrations prior to the system-of-systems 
preliminary design review, but some of those scheduled demonstrations 
are slipping. Appendix VII contains a list of all FCS critical 
technologies with their 2007 and 2008 TRL ratings and Army projections 
for attaining TRL 6. 

Thirteen of the technologies that the Army rated at TRL 6 are awaiting 
validation from technology review authorities--independent teams 
convened by the FCS program manager and from the Director, Defense 
Research and Engineering. These reviews could actually downgrade 
maturity levels if demonstration results do not support the Army's TRL 
designation. This occurred in 2007 with the mid-range munition's 
terminal guidance[Footnote 10]. In 2008, independent reviewers 
cautioned the Army about the maturity levels of three technologies: (1) 
JTRS ground mobile radio, (2) Mobile Ad-hoc Networking Protocols, and 
(3) Wideband Networking Waveforms. According to Army officials, the 
Army had claimed these technologies had demonstrated TRL 6; however, 
the independent reviewers suggested the Army consider providing 
additional justification to strengthen the case for a TRL 6. 
Consequently, it is not clear whether independent reviewers will concur 
with the Army's assertion that these technologies have demonstrated TRL 
6 maturity. Table 1 illustrates both the actual progress the Army has 
made maturing FCS critical technologies and projected progress through 
the production decision.

[End of table] 

As we have shown in the past, accepting lower technology levels in 
development frequently increases program schedule and cost. In the case 
of FCS, the downgrade in TRLs is particularly troublesome because TRL 6 
represents a significant development step over TRL 5. Army engineers 
maintain that anything beyond TRL 6 is a system integration matter and 
not necessarily technology development. Leading commercial firms treat 
adapting the technologies to the space, weight, and power demands of 
their intended environment--in essence, TRL 7--as part of technology 
development. Even if one accepts the lower standard of TRL 6 at program 
start, the integration of these technologies into systems and 
subsystems should have taken place in the first half of development, 
which DOD refers to as "system integration." As a complex, networked 
system-of-systems, FCS will have unprecedented integration issues. Yet, 
FCS system integration will have to occur in the second half of 
development, where it will compete for resources that are intended to 
be for demonstration of the system. 

As we have previously reported, advancing technologies to TRL 6 has 
been especially challenging.[Footnote 11] The Army's history of 
maturing FCS technologies does not inspire confidence that it will be 
able to execute the optimistic and challenging integration plans 
involved with advancing technologies to a TRL 7 before the production 
decision in 2013. 

Technologies critical to FCS survivability are illustrative of the 
program's technology maturity issues. FCS survivability involves a 
layered, network-centric approach that consists of detecting the enemy 
first to avoid being fired upon; if fired upon, neutralizing the 
incoming munition before it hits an FCS vehicle; and finally, having 
sufficient armor to defeat those munitions that make it through the 
preceding layers. Each of these layers depends on currently immature 
technologies to provide the aggregate survivability needed for FCS 
vehicles. Many of the technologies intended for survivability have 
experienced developmental delays. As a key component of FCS 
survivability, the short range active protection system is intended to 
neutralize incoming munitions and help protect vehicles from threats 
such as rocket-propelled grenades. Initially, Army requirements for the 
system included the ability to defeat long-range anti-armor threats, 
such as antitank missiles. However, Army officials have decided to 
delay demonstration of this capability until 2011 or 2012. The Army 
held a short-range active protection system demonstration in the latter 
part of 2008 and declared that the system had reached TRL 6. The 
results of these demonstrations are pending validation from technology 
review authorities. It is important to note that the Army plans to 
continue active protection system technology development and 
demonstration for some time to ensure that it is an operationally 
effective and safe capability. This is challenging because the active 
protection system is to provide 360-degree protection for the 
relatively lightly-armored FCS manned ground vehicles by using, among 
other things, sensors, processors, rocket motors, and a counter- 
munition warhead to counter multiple threats. 

Lightweight hull and vehicle armor technology for FCS vehicles is also 
problematic because it will not be sufficiently advanced to provide 
military usefulness for several years. The Army is developing armor- 
related critical technologies in a phased approach. The initial phase 
of armor development only recently demonstrated TRL 6. The results of 
these demonstrations are also pending validation from technology review 
authorities. The Army intends for that initial version to satisfy 
threshold (or minimally acceptable) survivability requirements and 
plans to use it only in prototypes of manned ground vehicles. The 
second phase of armor is expected to meet objective (or desired) 
survivability requirements but is not scheduled to reach TRL 5 until 
fiscal year 2011. Even then, Army engineers do not believe that armor 
design will meet weight requirements. The third phase will be used for 
low-rate production vehicles and is scheduled to demonstrate TRL 6 in 
2012. This armor is expected to satisfy objective threat requirements 
and be 25 percent lighter than the second armor iteration. The Army 
plans to mature the fourth and final phase of armor to a TRL 6 in 
fiscal year 2014. The Army also plans to make manufacturing technology 
investments in the armor area in order to reduce its production costs. 

Trade-offs Needed to Close Gaps between FCS Requirements and Designs: 

For the 2009 milestone review, Congress has directed DOD, for each 
system and network component of the program, to assess key design 
knowledge and risks, based on system functional reviews, preliminary 
design reviews, and technical readiness levels. Now tentatively 
scheduled for May 2009, the system-of-systems preliminary design review 
is a major technical review to assess whether the full suite of FCS 
systems and information network are ready for detailed design and that 
the FCS detailed performance requirements can be obtained within cost, 
schedule, risk, and other system constraints. 

The Army has continued to gain knowledge about FCS development, but 
design knowledge expected to be available at the time of the 2009 
milestone review may not provide confidence that FCS design risks are 
at acceptable levels. Key design risks include the Army's ability to 
accomplish all system-level design work in the time remaining before 
the 2009 system-of-systems preliminary design review, demonstrate that 
emerging system designs match detailed requirements, and mitigate 
recognized technical risks to acceptable levels. This challenge has its 
roots in the fact that the Army started FCS development in 2003 without 
establishing firm requirements and preliminary designs to meet those 
requirements; that is, demonstrating a match between customer needs and 
available resources. Consequently, the Army is still seeking to 
stabilize FCS designs at a time when the program is already past the 
mid-point of development phase--the point when a program following best 
practices and DOD policy would normally conduct a critical design 
review demonstrating a stable, producible design capable of meeting 
performance requirements. Having passed that mid-point, FCS is now far 
out of alignment with current DOD policy, which requires a program to 
show a match between requirements and resources at or shortly after 
development start. 

Over the past year, the Army has continued the process of setting and 
refining requirements in order to establish system designs. At the 
system-of-systems level, requirements are relatively stable. At the 
individual system level, requirements continue to evolve. The Army 
scheduled a series of 15 system-level preliminary design reviews, with 
the first held in 2007 and the last expected to occur in March 2009, in 
order to assess whether individual systems are ready to proceed into 
detailed design. Although the Army plans to conduct all system design 
reviews by the end of March 2009, the schedule to close out all the 
reviews may take some time, and requirements and design trade-offs will 
be necessary. Several examples are illustrative: 

* The preliminary design review for the Multi-Function 
Utility/Logistics and Equipment Vehicle occurred in December 2007 and 
noted critical design problems regarding vehicle weight reduction. The 
Army did not close the weight issue until some 10 months later, in 
October 2008. 

* The Small Unmanned Ground Vehicle had its preliminary design review 
in October 2008 and has now entered into detailed design. Operational 
requirements call for the vehicle to operate for 6 hours between 
battery changes within a temperature range of minus 25 degrees and 120 
degrees. However, the vehicle does not meet those requirements at any 
temperature. Even with optimum operating temperature, mission length is 
no longer than 5.4 hours. Additionally, the vehicle cannot satisfy 
operational requirements for storage at temperatures of 60 degrees 
below zero because its motor lubricant decomposes and battery becomes 
useless. Consequently, the Army now plans to remove the batteries and 
provide for special storage. 

* During the first part of the network preliminary design review held 
in November 2008, the Army recognized that there are significant gaps 
between the FCS requirements and the emerging network design. These 
include the JTRS handheld radio; ground mobile radio; and airborne, 
maritime, and fixed-station radios; the WIN-T increment 3; and the 
Wideband Networking Waveform and Soldier Radio Waveforms. The Army has 
not yet been able to obtain validation of its TRL 6 rating for JTRS 
ground mobile radio; the mobile, ad-hoc networking protocols; and 
Wideband Networking Waveforms. According to Army officials, if 
additional funding is provided and developments are fully successful, 
they will not fully meet FCS requirements until about 2017 or 2018. The 
Army conducted the second part of its network preliminary design review 
in January 2009. The results were not available for inclusion in this 
report. 

For several months, the Army has been conducting a series of technical 
reviews of various aspects of the FCS manned ground vehicle 
requirements and designs. Those efforts culminated at the manned ground 
vehicle preliminary design review in January 2009. The results of that 
review were not available in time for inclusion in this report. 

According to Army assessments, key risks remain within several areas: 
software development and integration, network and transport, manned and 
unmanned platforms, and average unit production cost. Many risks 
involve the likelihood that requirements may be unachievable when or as 
expected. The assessment of these risks will be a key determinant in 
the overall feasibility of the FCS concept and the ability to execute 
the FCS acquisition strategy going forward. FCS is also working to 
address significant areas of high risk such as network performance and 
scalability, immature network architecture, and synchronization of FCS 
with the JTRS and WIN-T programs. JTRS and WIN-T are also having 
difficulty with technology maturation and are at risk of being delayed 
or delivering incomplete capabilities to FCS. 

In a 2007 acquisition memorandum, DOD stated that its acquisition 
policy was to adjust requirements and technical content to deliver as 
much as possible of planned capability within budgeted cost. At the 
same time, it directed the services to establish Configuration Steering 
Boards in order to review all requirements changes and any significant 
technical configuration changes that have the potential to result in 
cost and schedule impacts. Despite this direction, the Army has not 
established a steering board for FCS. DOD officials told us that such a 
board would be useful for providing input to FCS requirements and 
design trade-offs. 

Army Has Not Yet Convincingly Demonstrated FCS Concept: 

In making the assessment of whether the FCS program should continue, 
Congress required DOD to make a determination on whether actual 
demonstrations, rather than simulations, have shown that the concept of 
the program will work. FCS brigade combat teams are expected to be able 
to execute a new tactical paradigm based on what the Army refers to as 
"the quality of firsts"--the capability to see first, understand first, 
act first, and finish decisively. Because this paradigm depends on the 
aggregate performance of interdependent FCS systems versus the 
performance of any single system, it is essential that this concept be 
proven through demonstrations. While modeling and simulation are 
essential to assessing the performance of FCS, they must be anchored in 
actual demonstrations. 

DOD will be challenged to meet the congressional direction to 
demonstrate (versus simulate) that the FCS warfighting concept will 
work by the time of the 2009 milestone review. At this point in the 
program, the FCS concept has been simulated but has not been 
convincingly demonstrated in any sort of field event. This stems from 
the fact that technologies have not finished development and prototype 
systems with the essential network components are not ready to be built 
yet. In preliminary field demonstrations, some people, sensors, and 
platforms have been connected and information was transferred from one 
to the other. Basic capabilities of the unmanned aerial and ground 
vehicles, as well as some of the unattended sensors and munitions, have 
been demonstrated. The manned ground vehicles have demonstrated some of 
their mobility and lethality capabilities. There have been some 
technology demonstrations of early versions of the lightweight armor 
and an active protection system, but the feasibility of the FCS 
survivability concept remains uncertain. Nothing approaching a 
demonstration of the "quality of firsts" paradigm has yet been 
attempted nor will it be before the 2009 milestone review. 

The Defense Acquisition Board has established criteria for the 2009 
Review including several in a category entitled "Test/Experimentation/ 
Demonstration." (See appendix IV.) However, none of the criteria 
address the issue of demonstrating that the FCS concept will work. 
Instead, the criteria call for the demonstration of some early FCS 
prototypes and the completion of some events such as a 2008 joint 
service experiment. The Defense Acquisition Board criteria also include 
several that call for delivery of certain early prototypes and others 
that call for demonstration of selected capabilities. Without 
questioning the value of these individual criteria, it is not clear 
what they will tell decision makers about the value or demonstration of 
the FCS concept as a whole. 

Demonstrations of FCS Network Performance Very Limited: 

In making the assessment of whether the FCS program should continue, 
Congress required DOD to make several determinations, including (1) 
whether actual demonstrations, rather than simulations, have shown that 
the software for the program is on a path to achieve threshold 
requirements on cost and schedule; (2) whether the program's planned 
major communications network demonstrations are sufficiently complex 
and realistic to inform major decision points; (3) the extent to which 
manned ground vehicle survivability is likely to be reduced in a 
degraded communications network environment; (4) the level of network 
degradation at which FCS manned ground vehicle survivability is 
significantly reduced; and (5) the extent to which the FCS 
communications network is capable of withstanding network attack, 
jamming, or other interference. 

In addition, the Assistant Secretary of Defense for Networks and 
Information Integration is required to submit a report to Congress on 
the FCS communications network and software. That report is to be 
submitted by September 30, 2009 and is to include an assessment of the 
communications network that will specifically address areas such as 
vulnerability to network attack, electronic warfare, adverse weather, 
and terrain; dependence on satellite communications support; and 
operational availability and performance under degraded conditions. The 
report is also to include assessments of the communications network's 
test schedule and Army efforts to synchronize funding, schedule, and 
technology maturity of critical networking programs with FCS. Appendix 
V contains the comprehensive criteria from the legislation directing 
this review. 

These assessments of the capabilities and vulnerabilities of the FCS 
network will be important in determining if the FCS concept is 
feasible. However, as we reported last year, the Army had an 
understanding of network requirements and how to build the network, but 
many challenges and work remained before the network would reach 
maturity.[Footnote 12] Hence, network development and demonstration is 
at a very early stage and therefore, the network assessments will most 
likely be based on analysis and simulations rather than demonstrated 
results. Even if software development proceeds on schedule and 
technical risks of key network elements, such as JTRS and WIN-T are 
successfully retired, the uncharted nature of the FCS network makes 
predicting its eventual performance difficult. Army test officials are 
assessing network scalability, which relates to increasing the number 
of radios, or nodes, on the network, through limited testing. However, 
the number of nodes used in testing to date has been limited, using 
only 30 nodes, while a brigade combat team may require as many as 5,000 
nodes. Considering that mobile, ad-hoc networks have limited 
scalability, and performance decreases as more nodes are added, the 
ultimate FCS network performance is difficult to predict. 

To date, actual demonstrations of FCS software have been limited to the 
early spin out tests and experiments, and it is not yet known whether 
the information network is technically capable of delivering the 
quality of service needed to make the FCS warfighting concept possible. 
[Footnote 13] At the time of the FCS milestone review in 2009, the 
extent of network demonstration is expected to be very limited. For 
example, in 2008, the Army demonstrated, among other basic 
capabilities, sensor control, terrain analysis, and unmanned platform 
planning and operations. Other limited demonstrations are scheduled on 
a regular basis. For example, in the 2008 joint service experiment, 
several portions of the FCS network--including an early version of the 
system-of-systems common operating environment, the unattended sensors, 
and Non-Line-of-Sight Launch System--were evaluated in terms of their 
basic operation and interoperability with other systems. The first 
major demonstration of the FCS network is the limited user test 
scheduled for fiscal year 2012, which will be at least a year after the 
critical design review and only about a year before the start of low- 
rate initial production for the core FCS program. This event comes 
after the vehicle designs on manned ground platforms have been 
established. One of the key objectives of that test will be to identify 
the contributions and limitations of the network regarding the ability 
of the FCS brigade combat team to conduct missions across the full 
spectrum of operations. However, the fully automated battle command 
system is not expected to be available until 2013 when the Army expects 
100 percent of the network capabilities, including software, to be 
available. 

As a key part of the overall FCS communications network, it is 
uncertain whether FCS software requirements can be achieved within cost 
and schedule estimates. The first of 4 software builds has been 
delivered and qualified, and build 2 is still in development, with a 
planned delivery in 2010. As we have reported earlier, FCS software 
estimates continue to grow, and the total estimate for the network and 
platforms is projected to total over 100 million lines of computer 
code, which is more than triple the size the program estimated in 2003. 
Army officials have identified 16 risks in the software arena, or 
specific areas where there is a risk of not achieving goals within cost 
and schedule estimates, including system-of-systems common operating 
environment, network management/quality of service, network security/ 
information assurance, distributed fusion management, and estimated 
effective source lines of code. According to Army officials, software 
development costs are capped at approximately $2.6 billion. As a 
result, Army officials stated that they have had to defer some planned 
FCS capabilities to later software builds. Yet, development experience 
to date, coupled with the risks yet to be resolved, raise questions as 
to whether the necessary software can be developed within cost and 
schedule estimates. Alternatively, the Army may have to reduce or 
eliminate FCS requirements. 

FCS Costs Are Expected to Increase Again and Affordability Is Still in 
Doubt: 

In making the assessment of whether the FCS program should continue, 
Congress required DOD to make a determination on (1) what the cost 
estimate for the program is, including spin outs, and an assessment of 
confidence levels for that estimate; and (2) what the affordability 
assessment for the program is, given projected Army budgets, based on 
that cost estimate. 

For the 2009 milestone review, DOD and the Army are expected to provide 
the updated program cost estimate and an affordability assessment for 
the FCS program. The Army has indicated that the most recent cost 
estimate for the program is no longer valid, but it has not yet 
completed an official updated estimate. While full details are not yet 
available, the Army is considering plans to request additional funds 
for FCS beyond the current cost estimate of $159 billion. Those plans 
would involve additional development costs of about $2 billion and 
procurement costs of about $17 billion over the current cost estimate. 
Where the Army has offset some cost increases in the past with 
reductions in program content, we are not yet aware of any similar 
actions to offset the expected cost increases. According to DOD 
officials, DOD's Cost Analysis Improvement Group is expected to prepare 
an updated independent cost estimate for the milestone review. Previous 
estimates from the group have been significantly higher than the 
Army's, particularly regarding the cost to develop software. DOD 
officials also stated that DOD's Program Analysis and Evaluation group 
may be tasked to provide input for an FCS affordability assessment. 
These assessments are intended to cover all of the costs, including 
those for the spin outs, which will be necessary to fully field the FCS 
program. This would be the first complete cost estimate that will 
include spin outs and other costs. The Army now projects that the costs 
of its revised FCS spin out initiative will be about $21 billion beyond 
the core FCS program costs of $159 billion. In addition to FCS-specific 
costs, complementary program costs are separate from FCS and represent 
significant additional commitments from the Army and other services. 
Several of these complementary programs have funding issues of their 
own. For example, the JTRS and the WIN-T programs are not yet fully 
funded to develop the full capabilities currently required by the FCS 
program. 

Ultimately, FCS's affordability will hinge on two factors: the actual 
cost of the program and the availability of funds. Heretofore, there 
has not been a sound basis for preparing a firm cost estimate. The 
preliminary design review process should provide a better foundation 
for one. Yet, such an estimate would have the confidence of a program 
in early development, with many risks and unprecedented challenges to 
meet. As it stands, FCS commands the largest portion of the Army's 
acquisition budget and, as currently planned, will continue to do so 
for many years. The Army continues to indicate its willingness to 
accept the high risks of the program and make trade-offs in both 
requirements and other programs to accommodate its growing costs. Since 
the program began, costs have increased from $92 billion to $159 
billion, which only covers the cost to equip one-third of the Army's 
active forces. Indicative of the tension between program costs and 
available funds, the Army recently proposed deferring upgrades to 
current systems such as the Abrams Tank and Bradley Fighting Vehicle to 
free up funds for FCS. This tension seems only likely to worsen, as 
indications are that FCS costs are about to increase again at the same 
time competition for funds--both between near-term and far-term needs 
within DOD and between defense and other needs within the federal 
government--is intensifying. The Army's position has been that it will 
reduce FCS capabilities to stay within available development funds but 
at some point, reductions in FCS capability--whether driven by money or 
technical feasibility--will fall below an acceptable level. That level 
appears as yet indefinable. 

Oversight Challenges Will Continue Beyond the Milestone Decision: 

The 2009 milestone review will not only require DOD to decide if FCS is 
technically feasible and militarily worthwhile, it will provide the 
opportunity to structure the emerging program so that it complies with 
current acquisition policy and is knowledge-based--thus more conducive 
to oversight. On several scores, the current FCS program falls short. 
Its acquisition strategy is more schedule-driven than it is knowledge- 
based and is unlikely to be executable, with a significant amount of 
development and demonstration yet to be completed. The timing of 
upcoming commitments to production funding puts decision makers in the 
difficult position of making production commitments without knowing if 
FCS will work as intended. For example, the Army plans for FCS core 
production to directly follow the early NLOS-C production, which may be 
premature based on design maturity and demonstrations expected to be 
done up to that point. Likewise, the Army's schedule for providing 
early FCS capabilities to current forces is hurried, as spin out 
systems may not be fully demonstrated before the Army commits to their 
production. Finally, the Army's potential adoption of an incremental 
approach to FCS acquisition could represent another major restructure 
of the program. While an incremental approach is generally preferable, 
it would represent the fourth different strategy for the FCS program 
that DOD and the Congress will be asked to evaluate and oversee. 

FCS Acquisition Strategy Is Not Knowledge-Based and May Not Be 
Executable Within Estimated Resources: 

We have previously reported that to date, the FCS program has advanced 
through acquisition milestones without having achieved the level of 
knowledge preferred by best practices and DOD's own policies and a 
commensurate level of information needed for oversight, given the scope 
of the program and the risks it entails.[Footnote 14] The issuance of 
DOD's 2008 acquisition instruction underscores the wide variance 
between policy and the FCS acquisition strategy. Ideally, requirements 
trades would already have been made and a high-confidence design 
established. This would position the program to move toward maturity as 
evidenced by such measures as successful completion of subsystem 
critical design reviews, maturity of critical manufacturing processes, 
planned corrective actions to hardware and software deficiencies, and 
adequate developmental testing. At this point, however, FCS has yet to 
establish a firm system-of-systems design and is several years from any 
large-scale testing at the system-of-systems level. The milestone 
review represents an opportunity to judge FCS on critical knowledge 
markers and set it on a more reasonable course with opportunities for 
effective and meaningful oversight from the Army, DOD, and the 
Congress. Under its current acquisition strategy, the FCS is neither 
knowledge-based nor does it lend itself to meaningful oversight. Figure 
2 compares a knowledge-based approach to developing a weapon system 
(consistent with DOD policy) with the approach taken for FCS. Best 
practices for successful product development include three knowledge 
points (KP). Knowledge Point 1 should occur at development start and is 
attained when technologies and resources match requirements; KP 2 
should occur at the mid-point between development and production and is 
attained when the product design performs as expected; and KP 3 should 
occur at production start and is attained when production can meet 
cost, schedule, and quality targets. Ideally the preliminary design 
review occurs at or near the start of development and the critical 
design review occurs mid-way through development.

FCS Approach:

[End of figure] 

As shown in figure 2 above, FCS technology development and system 
development and demonstration phases will overlap by several years. The 
Army has scheduled only 2 years between the critical design review in 
2011 and the production decision in 2013. This leaves little time to 
gain knowledge between the two events, and is particularly important 
because the critical design review is the point at which a program 
begins building fully-integrated, production-representative prototypes 
whose testing will prove the design's maturity and form the basis for 
the low-rate production decision. Instead, FCS will rely on less mature 
prototypes and the decision to proceed into production will be made 
without a mature design. As a result of the current acquisition 
approach, the FCS program may not be executable given the amount of 
development budget remaining and the development work that remains to 
be done, as illustrated in figure 3 below.

[End of figure] 

At the preliminary design review, the program expects to have all 
critical technologies mature to TRL 6, system-level requirements 
nearing completion, and a preliminary design available to reconcile 
technologies with requirements. Using DOD policy as a reference, this 
is about the point at which the FCS program should be ready to begin. 
Should the program be approved to continue on its present course at the 
2009 milestone review, the Army would have to complete development--in 
essence, the entire system development phase--with 40 percent of its 
financial and schedule resources remaining. This is not to judge either 
the value of the work done to date or the rate of progress, but rather 
to underscore where the program really is in terms of the development 
process. Accordingly, ahead of FCS remains what is typically the most 
expensive part of system development: completing the detailed system 
and network designs and building prototypes and using them to 
demonstrate that the system will work. In the case of FCS, there are 
the added challenges of integrating multiple technologies and showing 
that the system of systems as a whole will work, including the 
unprecedented network. 

The late completion of the system development activities that will 
demonstrate whether FCS can deliver the promised capability is at odds 
with the early requests for production funds. Additional maturation of 
critical technologies, followed by the challenging prospect of 
integrating FCS subsystems and systems, lies ahead. Design work is 
ongoing and many designs remain to be matured and verified. A key 
indicator of the Army's progress in this area will be the percentage of 
design drawings that will be released to manufacturing at the critical 
design review, currently scheduled for fiscal year 2011. The Army is 
currently fabricating key FCS prototypes, many of which are scheduled 
for delivery in the 2010 time frame. After they are delivered, much 
additional engineering work will remain to be conducted as part of a 
disciplined test, fix, and retest approach. For example, several 
prototypes will be built based on preliminary versus final designs, and 
will not have all key technologies integrated. In this sense, they will 
not be representative of production items. Many of the results of these 
demonstrations, and other key test and evaluation results, will not be 
available until late in the program, creating difficulty in applying 
knowledge gained from previous tests into subsequent tests. For 
example, a key system-of-systems test scheduled before the low-rate 
production decision is the limited user test 3 in 2012 to assess 
brigade combat team network capabilities. This test will be the first 
large-scale FCS test that will include a majority of the developmental 
prototypes and a large operational unit and occurs only one year before 
the low-rate initial production decision for the core FCS program. This 
test is important because the Congress has required a broad network 
demonstration to be conducted before starting low-rate production of 
the core FCS program. This demonstration is also expected to occur in 
fiscal year 2012 as part of the limited user test. Finally, the Army 
will have to develop and mature production processes for a wide range 
of FCS systems. 

Our work has shown that development costs for programs with mature 
technologies at the start of system development increased by a modest 
average of 4.8 percent over the original estimate, whereas development 
costs for programs with immature technologies increased by 34.9 
percent.[Footnote 15] Our work has also shown that most development 
cost growth occurs after the critical design review. Specifically, of 
the 28.3 percent cost growth that weapon systems average in 
development, 19.7 percent occurs after the critical design review. In 
the case of FCS, the Army's strategy is schedule-driven and calls for 
beginning low-rate production in 2013 and initial operational 
capability in 2015, which leaves little time to overcome the remaining 
technological and engineering challenges the program faces prior to 
committing to production. Thus, it is likely that under the current 
schedule, additional cost growth would be incurred as the Army works 
through these remaining challenges. 

According to DOD officials, the Systems and Software Engineering group, 
within DOD's Acquisition, Technology, and Logistics organization, has 
been tasked to conduct a systems engineering review of FCS that will 
include an evaluation of risks associated with the FCS acquisition 
strategy, test plans, software, and key complementary programs. 
According to the Systems and Software Engineering group, the assessment 
will also cover the FCS system engineering plan for reasonable exit 
criteria associated with critical design review and production 
readiness. The reporting objectives for this effort include, among 
other things, clearly illustrating the risks and challenges of 
proceeding to critical design review as planned. The Systems and 
Software Engineering group's review is expected to provide input to 
address three of the required congressional assessments--FCS 
requirements/design, concept demonstration, and software demonstration--
and should provide critical information on the amount of FCS 
development and demonstration work yet to be completed and its expected 
cost and schedule. 

Timing of Currently Planned Funding Commitments Puts Decision Makers in 
Difficult Position: 

Funding commitments for production begin before FCS capabilities are 
demonstrated and even before the critical design review is held. This 
puts decision makers in a difficult position, particularly when 
considering that FCS is to deliver more than a better set of equipment--
it embodies a new concept of combat. Procurement funding for core FCS 
production facilities will be requested for fiscal year 2011, the 
budget for which will be presented to Congress in February 2010--
several months after the milestone review and before the stability of 
the FCS design is assessed at the critical design review.[Footnote 16] 
In fact, based on results of system-level preliminary design reviews 
conducted to date, the Army could still be working to close action 
items resulting from the system-of-systems preliminary design review 
when it requests funding for FCS core production facilities. Further, 
when Congress is asked to approve funding for low-rate initial 
production of core FCS systems, the Army will not yet have proven that 
the FCS network and the program concept will work. A key demonstration 
of the FCS network, limited user test 3, is currently scheduled for 
later in 2012, after the Congress will have received the fiscal year 
2013 budget submission. This is illustrated further in figure 4 below.

Early NLOS-C Production May Portend Risks for FCS: 

Since fiscal year 2003, the Army has been required by Congress to 
develop and field the NLOS-C early in order to provide a self-propelled 
indirect fire capability.[Footnote 17] The Department of Defense 
Appropriations Act for 2008 required the Army to deliver eight NLOS-C 
prototypes by the end of calendar year 2008 and to field early 
production versions of the system by fiscal year 2010.[Footnote 18] 
These systems are to be in addition to those needed for developmental 
and operational testing. The Army determined that a set of 18, a full 
battalion's worth, would be needed to meet the intent of the act's 
language in terms of the early production units. Although the NLOS-C is 
one of eight FCS manned ground vehicles, it is proceeding about 5 years 
ahead of the other vehicles. 

The Army began procuring long-lead production items for the NLOS-C 
vehicle in 2008 to meet the requirement for the early production 
versions. According to program officials, an urgent need to build Mine- 
Resistant Ambush Protected vehicles diverted subcontractor resources 
away from the NLOS-C efforts. Officials further indicated that 
technological challenges associated with a lack of completed production 
facilities and specialized tooling also contributed to delays. The Army 
accepted delivery of the first two NLOS-C prototypes in fiscal year 
2008 and the remaining six vehicles in the following two years. A 
Defense Acquisition Board decision to begin low-rate production for the 
additional set of 18 NLOS-C vehicles was expected in December 2008. 
Details of that decision were not available for inclusion in this 
report. If approved, the Army expects delivery of six early production 
units per year in fiscal years 2010 through 2012. None of these early 
NLOS-C vehicles will meet FCS threshold requirements nor will they be 
operationally deployable. Rather, they will be used as training assets 
for the Army Evaluation Task Force. 

In order to meet the early fielding dates, the Army will begin 
production of the NLOS-C vehicles with immature technologies and 
designs. Several key technologies, such as lightweight armor, the 
active protection system, and the JTRS radios will not be fully mature 
for several years. Much requirements definition work remains for all 
the manned ground vehicles, including the NLOS-C. Software development 
is in its early stages. Design work on the manned ground vehicles also 
remains to be done, including work on the chassis and mission modules. 
Significant challenges involving integrating the technologies, 
software, and design will follow. To the extent that these aspects of 
the manned ground vehicles depart from the early production cannons, 
costly rework of the cannons may be necessary if they will ever be used 
for other than training purposes. 

The Army's efforts and financial investments made on the NLOS-C 
vehicles could create additional pressure to proceed with FCS core 
production, prior to achieving a solid basis of knowledge on which to 
move forward. Production on the cannon is beginning 5 years in advance 
of the production decision on the FCS core systems. By the time of that 
decision, in fiscal 2013, the Army plans to have invested about $12 
billion in FCS procurement funds and more than $50 billion for FCS 
overall. In addition, the Army also plans to invest millions in 
production facilities in which to build the vehicles. These activities 
all contribute to starting up the manned ground vehicle industrial 
base. If the FCS strategy goes according to plan, FCS core production 
would directly follow NLOS-C production, with long lead items for the 
FCS core program providing a transition. That may be premature based on 
the expected design maturity and demonstrations expected to be done to 
that point. DOD has attempted to make a distinction between NLOS-C and 
the core FCS program, but the linkages continue to exist in the FCS 
acquisition strategy. If decision makers were to consider delaying FCS 
core production because it was not ready, a gap could develop when 
early NLOS-C production ends. Sustaining the industrial base could then 
become an argument against an otherwise justified delay. 

FCS Spin Outs Will Not be Proven Prior to Production: 

The Army initiated spin out development in 2004, when it embarked on an 
effort to bring selected FCS capabilities to current force heavy 
brigade combat teams while development of the core FCS program remained 
under way. In 2006, the Army established the Army Evaluation Task Force 
to use, evaluate, and train with the spin out capabilities, and the 
Task Force began its testing under that brigade construct in early 
2008. In mid-2008, the Army changed its focus from fielding spin out 
equipment to heavy brigades and instead to field the equipment to 
infantry brigade combat teams beginning in fiscal year 2011.[Footnote 
19] Army officials stated that this change occurred because infantry 
brigades are the optimal forces to fight in an urban environment, are 
being used in combat more than other types of forces, and are the most 
vulnerable forces. Accordingly, the Army now proposes to have 43 
infantry brigade combat teams fully equipped with spin out equipment by 
2025 at a total cost of $21 billion, with over $5 billion to be 
provided in fiscal years 2010 to 2015. DOD officials have reviewed the 
Army's revised FCS spin out plans, but they have not yet made a 
decision to approve those plans. 

The switch to infantry brigades led the Army to abandon its previous 
plan for a series of three spin outs and instead pursue a two-phased 
effort termed "early" and "threshold" with respective planned 
production commitment dates of fiscal years 2010 and 2013. The early 
spin out items are not expected to meet all FCS threshold requirements 
nor will the threshold spin out items have the same network and battle 
command capabilities as in the core FCS program. The early spin out 
will include: 

* Non-Line-of-Sight Launch System, 

* Urban and Tactical Unattended Ground Sensors, 

* two types of Joint Tactical Radios, 

* integrated computer system, 

* early versions of the system-of-systems common operating environment 
and battle command software, 

* Small Unmanned Ground Vehicle, 

* Class I Unmanned Aerial Vehicle, and: 

* Ground Soldier System.[Footnote 20] 

The second phase of spin outs will include improved versions of the 
above systems as well as add the Multifunction Utility/Logistics and 
Equipment vehicle, Class IV Unmanned Aerial Vehicle, Armed Robotic 
Vehicle--Assault (Light), and Centralized Controller.[Footnote 21] 

With the advent of the new structure, the Army moved its initial spin 
out production decision from January 2009 to December 2009. However, 
testing to date has not made a convincing case for this production 
commitment for several reasons. First, the Army has conducted only one 
test focused on the infantry brigade combat team structure. The two 
initial spin out tests--a technical field test in early 2008 to verify 
technical aspects of the capabilities and force development test and 
evaluation in May 2008 to validate requirements and training associated 
with those capabilities--occurred prior to the restructure and 
therefore employed heavy brigade combat team constructs. While Army 
officials have indicated that the force development test results have 
applicability to the infantry brigades, the test's major objective in 
terms of construct was to confirm the organizational structure and 
equipment distribution for a spin out-equipped heavy brigade combat 
team. The third test in July 2008, a preliminary limited user test to 
assess maturity, interoperability, and contribution of spin out 
systems, did utilize the infantry brigade structure. However, because 
of the restructure, that test was a shortened 2-day version of an event 
originally planned as a much longer effort focused on the heavy brigade 
combat team. 

Additionally, testing completed to date employed spin out systems that 
are not in the form that will be fielded. In fact, four of the systems 
planned for the early spin out have only been tested in surrogate or 
non-production representative forms (not in a mature or final 
configuration). The Ground Soldier System has not yet been included in 
any testing. Table 2 shows the versions of the prototypes used in each 
of the three tests to date.

[End of table] 

Using surrogate and non-production representative systems is 
problematic because it does not conclusively show how well the spin out 
systems can address current force capability gaps in situational 
awareness, force protection, and lethality. Moreover, they limit the 
ability to translate spin out tactical operations from heavy brigade to 
infantry combat teams and from spin outs to the core FCS. In fact, 
DOD's current acquisition policy requires that systems meet approved 
requirements and are demonstrated in their intended environments using 
the selected production-representative articles before the engineering 
and manufacturing development phase--which precedes the production 
phase--can end. Army test officials and equipment users told us, and 
test reports for the 2008 spin out tests confirm, that the surrogates 
and non-production representative systems limited the ability to gauge 
system performance, forced adjustments in testing, and made it 
difficult to know whether beneficial lessons were learned in testing. 
Officials from the Army's independent testing organization, the Army 
Test and Evaluation Command, stated that prototype JTRS radios impact 
the ability to evaluate overall system effectiveness regarding such 
factors as range and reliability. They also noted that radio 
performance can impact tactics used by the testing unit. Army officials 
who actually participated in the testing expressed similar views, and 
noted that the surrogates limited tactical operations. As a result, 
they said, the Army is immature tactically in terms of what it knows 
about spin out operations. 

The three tests scheduled for 2009 will continue to include surrogate 
and non-production representative systems. As in past tests, surrogates 
will take the place of JTRS handheld radios in all three tests. As 
noted by Army testers, this surrogate radio has limited basic 
functionality and will impact the evaluation of performance for systems 
used in conjunction with it, including the Non-Line-of-Sight Launch 
System and unattended ground sensors. According to Army officials, they 
will not have production representative versions of this radio to test 
until initial operational test and evaluation in fiscal year 2011. In 
addition, JTRS ground mobile radios used in 2009 testing are to consist 
of a mix of non-production and production representative models, but 
the composition will be heavily weighted toward the non-production 
representative models. Of the 16 total radios planned for use in the 
limited user test, only 4 are expected to be the production 
representative version. Additionally, Army officials told us that if 
these radios are delayed, they will not be able to properly operate and 
evaluate the needed networking capabilities. 

The schedule for completing 2009 testing is tight, and the issues 
identified in the 2008 testing may not be resolved prior to the spin 
out production decision. According to Army and DOD officials, the Army 
Evaluation Task Force has proven extremely useful in identifying system 
issues and suggesting design changes. While the Army is working to 
improve spin out systems in accordance with the Task Force's testing 
observations and recommendations, it does not plan to prove out all 
final designs prior to the production decision. For example, the Army 
is redesigning the Tactical Unattended Ground Sensor because 2008 
testing showed that it had issues with range, battery life, and 
hardware reliability. However, the Army does not expect to have the 
final version of the redesigned sensor available until February 2010, 
after the initial spin out production decision has been made. The Army 
is also redesigning the Urban Unattended Ground Sensor in accordance 
with testing feedback because that sensor had issues with battery life, 
user set-up time, and display of data. A final version of that sensor 
will not be available until February 2010. Additionally, the JTRS 
ground mobile radio may not be able to achieve its schedule for a 
production decision, which would impact the FCS spin out initiative. 

The Army may be unable to thoroughly assess spin outs' military utility 
for current forces because testing planned for 2009 is very compressed 
and leaves little time for analysis before the production decision. 
Under the revised spin out structure, the Army expects to conduct 
technical field, force development, and limited user tests in a back- 
to-back period from July through September 2009. This schedule allows 
the Army only 12 weeks to conduct all the tests, assess tests results, 
and incorporate lessons learned from one test to the next. 
Additionally, the limited user test, the last test in the series before 
the production decision and arguably the most important in terms of 
demonstrating system interoperability and overall spin out military 
utility, is planned to conclude at the end of September. That means the 
Army only has 8 to12 weeks to assess those test results before DOD will 
make the expected December 2009 production decision. By comparison, the 
Army needed 8 months to produce its test report on the 2008 technical 
field test. A DOD testing official told us that, because of the testing 
schedule, the Army would be unable to analyze test results adequately 
before making decisions. Army officials acknowledged that the schedule 
is extremely compressed and noted that any delay in maturity or receipt 
of hardware and/or software would impact the test schedule. They also 
indicated that, because of the aggressive schedule, it might be 
necessary to change the order of the tests and hold the force 
development test after the limited user test. 

Potential Incremental Acquisition Approach for FCS Would Represent 
Another Major Restructuring: 

Army officials informed the Under Secretary of Defense for Acquisition, 
Technology, and Logistics that they are considering an incremental or 
block acquisition approach to FCS. Citing the need to set a path to a 
stable, executable baseline for FCS--one with appropriately scoped 
requirements--FCS program officials believe that by adopting an 
incremental or block approach, they may be better able to mitigate 
risks in four major areas. These areas include: immaturity of 
requirements for system survivability, network capability, and 
information assurance; limited availability of performance trade space 
to maintain program cost and schedule given current program risks 
(schedule risks, weight/survivability, cost growth); program not funded 
to Cost Analysis Improvement Group estimates and impact of 
congressional budget cuts; and continuing challenges in aligning 
schedules and expectations for multiple concurrent acquisitions (such 
as JTRS and WIN-T). 

Subsequent to the mid-2008 Defense Acquisition Board meeting, where the 
Army presented its case for its consideration of an incremental or 
block approach for FCS acquisition, the Under Secretary of Defense for 
Acquisition, Technology, and Logistics issued a memorandum directing 
the Army to, among other things, pursue this initiative. Moreover, the 
memorandum stipulated that the incremental approach to acquire FCS must 
be prioritized to meet the warfighter's most critical operational needs 
and present a stable, executable program. The Army has been conducting 
an analysis to define an incremental approach, which is expected to 
address organizational structure, platforms, warfighter needs, and 
unified battle command. This analysis will be coupled with DOD 
assessments of FCS design maturity (including technology readiness 
levels, network and platform readiness, and associated risks and costs) 
and program maturity (including program execution feasibility, program 
scope, resource availability, and program alternatives). The Army was 
expected to present the analysis results and incremental FCS program 
plan to the DOD in late 2008 or early 2009, but that had not occurred 
at the time of this report. According to a DOD official, the adoption 
of an incremental approach may affect both the FCS core program and the 
spin out initiative. For the core FCS program, adoption of an 
incremental approach may involve a phased development and demonstration 
of individual FCS performance requirements and/or a phased fielding of 
individual components of the FCS family of systems. For the spin out 
initiative, the Army is considering if and when it should spin out FCS 
capabilities to the Heavy and Stryker Brigade Combat Teams. 

Restructuring the FCS program around an incremental approach has the 
potential to alleviate the risks inherent in the current strategy. It 
also represents an opportunity to apply the policy and thus provide 
decision makers more information before key program commitments, like 
production funding, are made. Taking an incremental approach to new 
acquisitions, versus attempting to acquire full capability in one step, 
has been preferred by DOD policy and best practices since before FCS 
began in 2003. The December 2008 policy adds several key features that 
would benefit a restructured FCS program. These include: 

* establishment of configuration steering boards that are tasked to 
review all requirements changes and any significant technical 
configuration changes that have the potential to result in cost and 
schedule impacts to the program; 

* a post-preliminary design review assessment to be conducted where the 
results of the PDR and the program manager's assessment are considered 
to determine whether remedial action is necessary to achieve the 
program's objectives; 

* a critical design review, which is an opportunity to assess design 
maturity by measures such as completion of subsystem critical design 
reviews, the percentage of software and hardware product specifications 
and drawings completed, planned corrective actions to hardware and 
software deficiencies; adequate developmental testing, the maturity of 
critical manufacturing processes, and an estimate of system reliability 
based on demonstrated reliability rates; 

* a post-critical design review, which assesses the program manager's 
report on the critical design review to determine whether the program 
can meet its approved objectives or if adjustments should be made; and: 

* before production, a demonstration that the system meets requirements 
in its intended environment using a production-representative article, 
manufacturing processes have been effectively demonstrated in a pilot 
line environment, and industrial capabilities are reasonably available. 

On the other hand, the newness of the incremental approach could 
complicate oversight at this important juncture. For example, its 
approval will lag behind the congressional schedule for authorizing and 
appropriating fiscal year 2010 funds. Also, a new approach to FCS could 
affect the scope of the milestone review. Evaluation of the new 
approach will involve a number of factors, including whether: 

* the incremental approach adequately addresses program risks and 
unresolved questions on the feasibility of the FCS concept and its 
information network; 

* the initial increment of FCS capability is justifiable on its own, 
without being dependent on future increments; 

* each increment, including the first, will comply with current DOD 
policy as it applies to a new program starting at the preliminary 
design review stage; and: 

* the Army's overall investment plan and resources for FCS increments, 
spin outs, and its current forces is sound and affordable. 

Should an incremental approach to FCS be pursued, one consideration 
will be the future role of the Army's contracting relationship with the 
LSI. We have previously reported the uniquely close relationship that 
exists between the Army and the LSI.[Footnote 22] While this has 
advantages, it also has disadvantages. In the past two years, the role 
of the LSI, originally limited to development, has grown relative to 
production. It is expected to be the prime contractor for production of 
spin outs, the NLOS-C, and at least the low-rate production of the FCS 
core systems. The specific role the LSI will play in production of spin 
outs, NLOS-C, and FCS core production remains somewhat unclear. 
Statements of work for the production contracts have not yet been 
negotiated. According to the program officials, the LSI will contract 
with the first tier subcontractors, which will in turn contract with 
their own subcontractors. Thus, the production role of the LSI is 
likely to be largely in oversight of the first tier subcontractors 
versus fabricating systems or subsystems. The LSI is also responsible 
for defining and maintaining a growth strategy for integrating new 
technologies into the FCS brigade combat teams. Combined with a likely 
role in sustainment, the LSI will remain involved in the FCS program 
indefinitely. 

Recently, the Under Secretary of Defense for Acquisition, Technology, 
and Logistics issued a directive to pursue alternate arrangements for 
any future FCS contracts. The Under Secretary found that the fixed fee 
was too high and the fee structure allows industry to receive most of 
the incentive fee dollars prior to demonstrating integrated FCS system- 
of-systems capability. The Under Secretary also directed that the Army 
conduct a risk-based assessment to examine contracting alternatives for 
FCS capability. This assessment is to evaluate opportunities for 
procurement breakout of the individual platforms/systems that comprise 
FCS and how the government's interests are served by contracting with 
the LSI as compared to contracting directly with the manufacturers of 
the items. 

Conclusions: 

The 2009 milestone review is the most important decision on the Future 
Combat System since the program began in 2003. If the preliminary 
design reviews are successfully completed and critical technologies 
mature as planned in 2009, the FCS program will essentially be at a 
stage that statute and DOD policy would consider as being ready to 
start development. In this sense, the 2009 review will complete the 
evaluative process that began with the original 2003 milestone 
decision. Further, when considering that the current estimate for FCS 
ranges from $159 billion to $200 billion when the potential increases 
to core program costs and estimated costs of spin outs are included, 90 
percent or more of the investment in the program lies ahead. Even if a 
new, incremental approach to FCS is approved, a full milestone review 
that carries the responsibility of a go/no-go decision is still in 
order, along with the attendant reports and analyses that are required 
inputs. In the meantime, establishing a configuration steering board, 
as suggested in DOD policy, may help bridge the gaps between 
requirements and system designs and help in the timely completion of 
the FCS preliminary design reviews. 

At this point, there are at least three programmatic directions, or 
some combination thereof, that DOD could take at the milestone review 
to shape investments in combat systems for the Army, each of which 
presents challenges. First, the FCS program as currently structured has 
significant risks and may not be executable within remaining resources. 
Second, although an incremental approach may improve the Army's 
prospects for fielding some capability, each increment must stand on 
its own and not be dependent on future increments. Third, spin outs to 
current forces currently rely on a rushed schedule that calls for 
making production decisions before production-representative prototypes 
have clearly demonstrated a useful military capability. The role of the 
LSI in the FCS production phase will be a factor that will have to be 
considered for any program that emerges from the milestone review. 

There is no question that the Army needs to ensure its forces are well- 
equipped. The Army has vigorously pursued FCS as the solution, a 
concept and an approach that is unconventional, yet with many good 
features. The difficulties and redirections experienced by the program 
should be seen as revealing its immaturity, rather than as the basis 
for criticism. However, at this point, enough time and money have been 
expended that the program should be evaluated at the 2009 milestone 
review based on what it has shown, not on what it could show. The Army 
should not pursue FCS at any cost, nor should it settle for whatever 
the FCS program produces under fixed resources. Rather, the program 
direction taken after the milestone review must strike a balance 
between near-term and long-term needs, realistic funding expectations, 
and a sound plan for execution. Regarding execution, the review 
represents an opportunity to ensure that the emerging investment 
program be put on the soundest possible footing by applying the best 
standards available, like those contained in DOD's 2008 acquisition 
policy, and requiring clear demonstrations of the FCS concept and 
network before any commitment to production of core FCS systems. 

Any decision the Army makes to change the FCS program is likely to lag 
behind the congressional schedule for authorizing and appropriating 
fiscal year 2010 funds. Because of this, Congress needs to preserve its 
options for ensuring it has adequate knowledge on which to base funding 
decisions. Specifically, it does not seem reasonable to expect Congress 
to provide full fiscal year 2010 funding for the program before the 
milestone review is held nor production funding before system designs 
are stable and validated in testing. 

Matters for Congressional Consideration: 

The Congress should consider taking the following two actions: 

* restricting the budget authority to be provided for FCS in fiscal 
year 2010 until DOD fully complies with the statutory FCS milestone 
review requirements and provides a complete budget justification 
package for any program that emerges, and: 

* not approving any production or long lead item funds for the core FCS 
program until the critical design review is satisfactorily completed 
and demonstrations using prototypes provide confidence that the FCS 
system-of-systems operating with the communications network will be 
able to meet its requirements. 

Recommendations for Executive Action: 

We recommend that the Secretary of Defense: 

* ensure that the investment program that emerges from the 2009 
milestone review be conformed with current DOD acquisition policy, 
particularly regarding technology maturity, critical design reviews, 
and demonstrating production-representative prototypes before making 
production commitments; 

* direct the Secretary of the Army to convene, following the 
preliminary design reviews and in time to inform the 2009 FCS milestone 
review, an FCS Configuration Steering Board to provide assistance in 
formulating acceptable trade-offs to bridge the gaps between the FCS 
requirements and the system designs; 

* ensure that if an incremental approach is selected for FCS, the first 
increments are justifiable on their own as worthwhile capabilities that 
are not dependent on future increments for their value, particularly 
regarding the order in which the information network and individual 
manned ground vehicles will be developed; 

* ensure that FCS systems to be spun out to current forces have been 
successfully tested in production-representative form before they are 
approved for initial production; and: 

* reassess the appropriate role of the LSI in the FCS program, 
particularly regarding its involvement in production. 

Agency Comments and Our Evaluation: 

DOD concurred with all our recommendations and provided comments on 
two. Regarding our recommendation on testing spin out systems, DOD 
commented that any production decision for FCS systems going to the 
current force will be informed by an operational assessment or user 
test of the systems. Although the Army plans to conduct such testing 
prior to the spin out low-rate initial production decision in late 
2009, that testing will employ surrogate and non-production 
representative systems. We maintain that any systems planned for 
production should be production-representative and thoroughly tested in 
a realistic environment. DOD noted that such testing was more in line 
with what is required for the full-rate production decision versus the 
initial low-rate decision. The testing standards we apply reflect the 
best practice and DOD policy of having production-representative 
prototypes tested prior to a low-rate production decision. This 
approach demonstrates the prototypes' performance and reliability as 
well as manufacturing processes--in short, that the product is ready to 
be manufactured within cost, schedule, and quality goals. In fact, 
current DOD policy states that development "shall end when the system 
meets approved requirements and is demonstrated in its intended 
environment, using the selected production-representative article; 
manufacturing processes have been effectively demonstrated in a pilot 
line environment; industrial capabilities are reasonably available; and 
the system meets or exceeds exit criteria and [low-rate initial 
production] entrance requirements." 

Regarding our recommendation about reassessing the role of the LSI, DOD 
stated that the FCS contractual arrangement is not an LSI contract as 
defined by law. According to the Duncan Hunter National Defense 
Authorization Act for Fiscal Year 2009, the FCS prime contractor "shall 
be considered to be a lead systems integrator until 45 days after the 
Secretary of the Army certifies in writing to the congressional defense 
committees that such contractor is no longer serving as the lead 
systems integrator."[Footnote 23] Army officials have stated that they 
are unaware of the Army preparing any such certification for the 
defense committees. Regardless of how the prime contractor is 
characterized, it was originally envisioned by the Army as an LSI, and 
its unusually close relationship with the Army on the FCS program still 
warrants additional oversight. 

Regarding our matters for congressional consideration, DOD expressed 
concern over the impact to FCS acquisition execution with the fiscal 
year 2010 budget authority limitations that we suggested Congress 
consider. We believe a restriction is necessary as congressional 
committees will be asked to provide funds for fiscal year 2010 before 
the FCS milestone review, currently scheduled for July 30, 2009, is 
held. The review will lead to a decision on whether the program should 
continue as currently structured, continue in restructured form, or be 
terminated. The scope and significance of those decisions create the 
possibility that the Army's fiscal year 2010 budget plans for FCS could 
differ significantly from the request that Congress will consider. A 
restriction need not amount to a denial or reduction of funds, but 
rather creates an opportunity for Congress to review any change in Army 
plans before releasing funds for FCS for the entire fiscal year. 

We received other technical comments from DOD, which have been 
addressed in the report, as appropriate. 

We are sending copies of this report to the Secretary of Defense; the

Appendix I: Scope and Methodology: 

To develop information on to what extent knowledge will likely be 
available to DOD and the Congress in the key areas of technology, 
design, demonstrations, network performance, and cost and affordability 
to support the 2009 milestone review, and the execution challenges that 
a post-milestone review FCS program presents to DOD and the Congress, 
we interviewed officials of the Office of the Under Secretary of 
Defense (Acquisition, Technology, and Logistics); the Secretary of 
Defense's Cost Analysis Improvement Group; the Secretary of Defense's 
Program Analysis and Evaluation; Director Defense Research and 
Engineering; the Joint Staff; Assistant Secretary of Defense (Networks 
and Information Integration); the Army's Training and Doctrine Command; 
the Director of Operational Test and Evaluation; the Future Force 
Integration Directorate; the Army Evaluation Task Force, the Army Test 
and Evaluation Command; the Director of the Combined Test Organization; 
the Program Manager, Future Combat System (Brigade Combat Team); and 
the Project Manager, Future Combat System Spin Out. 

We reviewed relevant Army and DOD documents, including the Future 
Combat System's Operational Requirements Document, the Acquisition 
Strategy Report, the Selected Acquisition Report, critical technology 
assessments and technology risk mitigation plans, and spin out test 
results. 

We attended system-level preliminary design reviews, board of directors 
reviews, and system demonstrations. In our assessment of the FCS, we 
used the knowledge-based acquisition practices drawn from our large 
body of past work as well as DOD's acquisition policy and the 
experiences of other programs. 

We certify that officials from DOD and the Army have provided us access 
to sufficient information to make informed judgments on the matters in 
this report. We discussed the issues presented in this report with 
officials from the Army and the Secretary of Defense and made several 
changes as a result. We conducted this performance audit from March 
2008 to March 2009 in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit 
to obtain sufficient, appropriate evidence to provide a reasonable 
basis for our findings and conclusions based on our audit objectives. 
We believe that the evidence obtained provides a reasonable basis for 
our findings and conclusions based on our audit objectives.

Appendix II: Comments from the Department of Defense: 

Office Of The Under Secretary Of Defense: 
Acquisition Technology And Logistics: 
3000 Defense Pentagon: 
Washington, DC 20301-3000: 

March 3, 2009: 

Mr. Paul L. Francis: 
Director, Acquisition and Sourcing Management: 
U.S. Government Accountability Office: 
441 G Street, N.W. 
Washington, DC 20548: 

Dear Mr. Francis: 

This is the Department of Defense (DoD) response to the GAO Draft 
Report, GAO-09-288, "Defense Acquisitions: Decisions Needed to Shape 
Army's Combat Systems for the Future," dated February 2, 2009 (GAO Code 
120740). 

The report recommends Congress (1) consider restricting the budget 
authority for Future Combat Systems (FCS) in Fiscal Year (FY) 2010 
until the Department complies with statutory FCS review requirements 
and (2) not approve production or long lead item funds for the core FCS 
program until the critical design review is completed and 
demonstrations using prototypes provide confidence that FCS will meet 
its requirements. The Department is concerned with the impact to FCS 
acquisition execution with the FY2010 FCS budget authority limitations 
GAO is recommending to Congress. Also of note, GAO's recommended 
testing requirements in support of the low-rate initial production 
decision is more in line with the testing required for Initial 
Operational Test and Evaluation, which occurs with low-rate production 
assets and informs the full rate production decision. 

The report recommends that the Secretary of Defense ensure the FCS 
program conforms to current defense acquisition policy, direct the Army 
to convene a Configuration Steering Board, ensure any increments of FCS 
capability are justifiable on their own, ensure any systems going to 
the current forces have been successfully tested, and reassess the 
involvement of the FCS contractor in production. 

The Department concurs with the GAO recommendations and our comments 
are enclosed. It should be noted, the FCS contractual arrangement is 
not an LSI contract as defined by law. Detailed technical comments were 
provided separately. 

Sincerely, 

Signed by: 

David G. Ahern:

GAO Draft Report Dated February 2, 2009: 
GAO-09-288 (GAO Code 120740): 

"Defense Acquisitions: Decisions Needed To Shape Army's Combat
Systems For The Future" 

Department Of Defense Comments To The GAO Recommendations: 

Recommendation I: The GAO recommended that the Secretary of Defense 
ensure that the investment program that emerges from the 2009 milestone 
review be conformed with current DoD acquisition policy, particularly 
regarding technology maturity, critical design reviews, and 
demonstrating production-representative prototypes before making 
production commitments. 

DOD Response: Concur. 

Recommendation 2: The GAO recommended that the Secretary of Defense 
direct the Secretary of the Army to convene, following the preliminary 
design reviews and in time to inform the 2009 Future Combat System 
(FCS) milestone review, an FCS Configuration Steering Board to provide 
assistance in formulating acceptable trade-offs to bridge the gaps 
between the FCS requirements and the system designs. 

DOD Response: Concur. 

Recommendation 3: The GAO recommended that the Secretary of Defense 
ensure that if an incremental approach is selected for FCS, the first 
increments are justifiable on their own as worthwhile capabilities that 
are not dependent on future increments for their value, particularly 
regarding the order in which the information network and individual 
manned ground vehicles
will be developed. 

DOD Response: Concur. 

Recommendation 4: The GAO recommended that the Secretary of Defense 
ensure that FCS systems to be spun out to current forces have been 
successfully tested in production-representative form before they are 
approved for initial production. 

DOD Response: Concur. Any Milestone C decisions on FCS systems going to 
the current force will be informed by an operational assessment or user 
test of the systems. 

Recommendation 5: The GAO recommended that the Secretary of Defense 
reassess the appropriate role of the lead system integrator (LSI) in 
the FCS program, particularly regarding its involvement in production. 

DOD Response: Concur. In November 2008, the USD(AT&L) directed the 
Secretary of the Army to examine contracting alternatives for 
procurement of FCS capability. The FCS contractual arrangement is not 
an LSI contract as defined by law.

Appendix VI: Technology Readiness Levels: 

Technology Readiness Levels (TRL) are measures pioneered by the 
National Aeronautics and Space Administration and adopted by DOD to 
determine whether technologies were sufficiently mature to be 
incorporated into a weapon system. Our prior work has found TRLs to be 
a valuable decision-making tool because they can presage the likely 
consequences of incorporating a technology at a given level of maturity 
into a product development. The maturity level of a technology can 
range from paper studies (TRL 1), to prototypes that can be tested in a 
realistic environment (TRL 7), to an actual system that has proven 
itself in mission operations (TRL 9). According to DOD acquisition 
policy, a technology should have been demonstrated in a relevant 
environment or, preferably, in an operational environment (TRL 7) to be 
considered mature enough to use for product development. Best practices 
of leading commercial firms and successful DOD programs have shown that 
critical technologies should be mature to at least a TRL 7 before the 
start of product development. 

Table 3: TRL Descriptions: 

Technology readiness level: 1. Basic principles observed and reported; 
Description: Lowest level of technology readiness. Scientific research 
begins to be translated into applied research and development. Examples 
might include paper studies of a technology's basic properties; 
Hardware and software: None (paper studies and analysis); 
Demonstration environment: None. 

Technology readiness level: 2. Technology concept and/or application 
formulated; 
Description: Invention begins. Once basic principles are observed, 
practical applications can be invented. The application is speculative 
and there is no proof or detailed analysis to support the assumption. 
Examples are still limited to paper studies; 
Hardware and software: None (paper studies and analysis); 
Demonstration environment: None. 

Technology readiness level: 3. Analytical and experimental critical 
function and/or characteristic proof of concept; 
Description: Active research and development is initiated. This 
includes analytical studies and laboratory studies to physically 
validate analytical predictions of separate elements of the technology. 
Examples include components that are not yet integrated or 
representative; 
Hardware and software: Analytical studies and demonstration of non-
scale individual components (pieces of subsystem); 
Demonstration environment: Lab. 

Technology readiness level: 4. Component and/or breadboard. Validation 
in laboratory environment; 
Description: Basic technological components are integrated to establish 
that the pieces will work together. This is relatively "low fidelity" 
compared to the eventual system. Examples include integration of "ad 
hoc" hardware in a laboratory; 
Hardware and software: Low-fidelity breadboard. Integration of non-
scale components to show pieces will work together. Not fully 
functional or form or fit but representative of technically feasible 
approach suitable for flight articles; 
Demonstration environment: Lab. 

Technology readiness level: 5. Component and/or breadboard validation 
in relevant environment; 
Description: Fidelity of breadboard technology increases significantly. 
The basic technological components are integrated with reasonably 
realistic supporting elements so that the technology can be tested in a 
simulated environment. Examples include "high fidelity" laboratory 
Integration of components; 
Hardware and software: High-fidelity breadboard. Functionally 
equivalent but not necessarily form and/or fit (size, weight, 
materials, etc.). Should be approaching appropriate scale. May include 
integration of several components with reasonably realistic support 
elements/subsystems to demonstrate functionality; 
Demonstration environment: Lab demonstrating functionality but not form 
and fit. May include flight demonstrating breadboard in surrogate 
aircraft. Technology ready for detailed design studies. 

Technology readiness level: 6. System/subsystem model or prototype 
demonstration in a relevant environment; 
Description: Representative model or prototype system, which is well 
beyond the breadboard tested for TRL 5, is tested in a relevant 
environment. Represents a major step up in a technology's demonstrated 
readiness. Examples include testing a prototype in a high-fidelity 
laboratory environment or in simulated operational environment; 
Hardware and software: Prototype--Should be very close to form, fit, 
and function. Probably includes the integration of many new components 
and realistic supporting elements/subsystems if needed to demonstrate 
full functionality of the subsystem; 
Demonstration environment: High-fidelity lab demonstration or limited/ 
restricted flight demonstration for a relevant environment. Integration 
of technology is well defined. 

Technology readiness level: 7. System prototype demonstration in an 
operational environment; 
Description: Prototype near or at planned operational system. 
Represents a major step up from TRL 6, requiring the demonstration of 
an actual system prototype in an operational environment, such as in an 
aircraft, vehicle, or space. Examples include testing the prototype in 
a test bed aircraft; 
Hardware and software: Prototype. Should be form, fit, and function 
integrated with other key supporting elements/subsystems to demonstrate 
full functionality of subsystem; 
Demonstration environment: Flight demonstration in representative 
operational environment such as flying test bed or demonstrator 
aircraft. Technology is well substantiated with test data. 

Technology readiness level: 8. Actual system completed and "flight 
qualified" through test and demonstration; 
Description: Technology has been proven to work in its final form and 
under expected conditions. In almost all cases, this TRL represents the 
end of true system development. Examples include developmental test and 
evaluation of the system in its intended weapon system to determine if 
it meets design specifications; 
Hardware and software: Flight-qualified hardware; 
Demonstration environment: Developmental test and evaluation in the 
actual system application. 

Technology readiness level: 9. Actual system "flight proven" through 
successful mission operations; 
Description: Actual application of the technology in its final form and 
under mission conditions, such as those encountered in operational test 
and evaluation. In almost all cases, this is the end of the last "bug 
fixing" aspects of true system development. Examples include using the 
system under operational mission conditions; 
Hardware and software: Actual system in final form; 
Demonstration environment: Operational test and evaluation in 
operational mission conditions.
