Why GAO Did This Study: 

The Department of Defense (DOD) is experiencing a growing demand for 
intelligence, surveillance, and reconnaissance (ISR) assets to provide 
vital information in support of military operations. Over the next 7 
years, DOD plans to invest over $28 billion in existing and new 
airborne ISR acquisition systems. This represents a marked increase 
over prior ISR investments. 

Given the significant investments, GAO was asked to (1) evaluate 
various ISR platforms for potential synergies and assess their cost and 
schedule status and the impact of any increases or delays on legacy 
systems and (2) assess the effectiveness of ISR investment decisions. 
To assess cost and schedule status, we reviewed programmatic and budget 
documentation. To evaluate investment decisions, we collected data on 
system capability, mission, and concept of operation and analyzed them 
for similarities 

What GAO Found: 

DOD plans to invest over $28 billion over the next 7 years to develop, 
procure, and modernize 20 major airborne intelligence, surveillance and 
reconnaissance systems. Nearly all of the systems in development have 
experienced cost growth or schedule delays. These problems have delayed 
the fielding of a warfighting capability and have resulted in program 
restructuring, cancellation, or unplanned investments in older legacy 
ISR systems. For example, problems in developing the Aerial Common 
Sensor affected three legacy programs, increasing their collective 
budgets by 185 percent, or nearly $900 million. In many cases, GAO 
found that the newer ISR programs lacked a solid business case or a 
knowledge-based acquisition strategy before entering the development 
process. A good business case requires the manager to match the system 
requirements with mature technologies and a system design that can be 
built. This requires sufficient knowledge about the system gained 
through basic system engineering concepts and practices. Although it 
fights jointly, DOD does not always procure new systems jointly. 
Instead, each service typically develops and procures systems 
independently. Opportunities exist for different services to 
collaborate on the development of similar weapon systems as a means for 
creating a more efficient and affordable way of providing new 
capabilities to the warfighter. GAO identified development programs 
where program managers and services are working together to gain these 
efficiencies and other programs that have less collaborative efforts 
and could lead to more costly stovepiped solutions. For example, the 
Navy and Army have collaborated successfully on the Fire Scout, but in 
contrast, the Air Force and Army have not been as collaborative on the 
Predator and Warrior systems, as they each currently plan unique 
solutions to their similar needs.

What GAO Recommends: 

GAO is recommending that DOD (1) develop and implement an integrated 
enterprise-level investment strategy approach that draws on the results 
of ongoing studies and (2) report to the defense committees by August 
1, 2007, the results of the ISR studies and identify specific plans and 
actions it intends to get greater jointness in ISR programs. DOD 
generally believes current initiatives will address our 
recommendations.

The Honorable Neil Abercrombie: 
Chairman: 
Subcommittee on Air and Land Forces: 
Committee on Armed Services: 
House of Representatives: 

Over the next 7 years, the Department of Defense (DOD) plans to invest 
over $28 billion to develop, procure, and modify 20 major airborne 
intelligence, surveillance, and reconnaissance (ISR) systems and 
maintain existing systems until the new ones are fielded. This planned 
investment represents a significant increase over past ISR investments 
and comes in response to threats that have emerged over the past decade 
and the high priority commanders have placed on gathering battlefield 
intelligence. 

Given the significant planned investment in ISR and DOD's recent focus 
on its acquisition strategy, you asked us to review DOD's ISR 
acquisition strategy. Specifically, we assessed 1) the cost and 
schedule status of ISR systems under development as well as investments 
planned for those systems currently in the DOD inventory and 2) the 
effectiveness of ISR investment decisions. 

To assess the cost and schedule status of ISR systems, we reviewed 
programmatic and budget documentation. To evaluate the effectiveness of 
decisions for planned investments, we collected information on system 
capability, mission, and concept of operation and analyzed the data for 
similarities. We also discussed the results of our analyses with 
officials at the program office; Army, Navy, and Air Force 
headquarters; the Under Secretary of Defense for Intelligence; and the 
Joint Chief of Staff for Intelligence. (For more on our scope and 
methodology, see app. I.) We conducted our work between June 2006 and 
April 2007 in accordance with generally accepted government auditing 
standards. 

In addition to this report, GAO is conducting two related review 
efforts for the committee. These efforts will review and report on 1) 
DOD's process to set requirements for ISR systems and 2) DOD's process 
for integrating unmanned aerial systems (UAS) into ongoing combat 
operations in support of ISR requirements. Two separate reports on 
these issues will be provided later in 2007. 

Results in Brief: 

Nearly all of the ISR development programs that we reviewed have 
experienced some cost or schedule growth. Cost and schedule growth in 
these programs is largely the result of a poor business case or 
acquisition strategy that failed to capture sufficient knowledge about 
the product technologies and design before committing to the 
development and demonstration of a new system. For example, the Global 
Hawk program--which experienced a 261 percent cost growth--had 
significant overlap of technology maturation, design, and production. 
Significant delays in the delivery of some new systems, breaking the 
investment strategy (for the new and legacy systems to be replaced) 
established at the start of these acquisition programs, have required 
DOD to make additional unplanned investments in legacy systems in order 
to keep them relevant and operational longer than planned. For example, 
the termination of the Aerial Common Sensor development contract 
resulted in a 5-year delay and the need to modify three legacy systems 
to keep them in the field longer than planned. The cost to keep these 
systems capable is estimated at $1.4 billion between fiscal years 2008 
and 2013, an increase of nearly $900 million over previous estimates to 
do so. These unplanned investments represent opportunity costs that 
could have been used for other needs within DOD had the original Aerial 
Common Sensor acquisition strategy been based on more robust design 
knowledge. 

Among the ISR acquisition programs we reviewed, we found specific cases 
where the military services have successfully collaborated to provide 
capabilities to the warfighter more efficiently and affordably. For 
example, the Army and Navy programs on their own initiative 
collaborated successfully on the Fire Scout to use a single contract to 
buy common components that can save hundreds of millions of dollars. 
However, we also found cases where more collaboration is needed to 
achieve efficiencies in costs and schedule and to close gaps in 
capabilities. For example, despite similarities in the Air Force's 
Predator program and the Army's Warrior program, the two services have 
resisted collaboration, and the Army awarded a separate development 
contract to the same contractor producing the Predator. Although the 
Army and Air Force agreed to consider cooperating on the acquisition of 
the two systems in January 2006, the services continue to struggle to 
agree on requirements and a concept of operation. Through 
collaboration, the services could leverage knowledge early in the 
acquisition process and avoid or reduce DOD costs for design, new 
tooling, and manufacturing, and streamline contracting and acquisition 
processes. DOD has numerous ISR studies, either recently completed or 
ongoing, and a pilot program to investigate portfolio management 
practices, but there have been no current actions to gain greater 
jointness in ISR acquisition programs. 

While DOD has numerous ISR studies, either recently completed or 
ongoing and including a pilot program to investigate portfolio 
management practices, there have been no substantive actions recently 
implemented to gain greater jointness in ISR acquisition programs. 

Therefore, we are recommending that DOD (1) develop and implement an 
integrated enterprise-level investment strategy approach that draws on 
the results of ongoing studies like portfolio management and (2) report 
to the defense committees by August 1, 2007, the results of the ISR 
studies and identify the specific plans and actions it intends to get 
greater jointness in ISR programs. DOD agreed with the first 
recommendation but believes that current initiatives will address it. 
We believe that many of the ongoing initiatives to achieve a greater 
integrated investment strategy approach for ISR are steps in the right 
direction but are concerned that they will not go far enough to address 
the problems that have occurred in DOD acquisitions for some time now. 
DOD also agreed to report the interim status on the portfolio 
management program by the above date but suggested moving the suspense 
date for reporting on the results of two other pertinent efforts to the 
end of the calendar year. We believe a full reporting in December 2007 
would be useful if it includes DOD’s detailed plans. However, we 
believe an interim reporting to the committees on the results and 
planned outcomes from completed studies should be provided to the 
committees by August 2007. 

Background: 

ISR directly supports the planning and conduct of current and future 
military operations. ISR encompasses multiple activities related to the 
planning and operation of sensors and assets that collect, process, and 
disseminate data. Intelligence data can take many forms, including 
electro-optical (EO) and infrared (IR) images, full-motion video (FMV), 
images from a synthetic aperture radar (SAR), electronics intelligence 
(ELINT), communications intelligence (COMINT), and measures and 
signature intelligence (MASINT). This data can come from a variety of 
sources, including surveillance and reconnaissance systems that operate 
in space or on manned or unmanned systems. Data can also come from 
systems that are ground-or sea-based or from human intelligence teams. 
Table 1 summarizes the ISR programs that we reviewed, 13 of which are 
in development. (A brief description of each of the 20 programs we 
reviewed is provided in app II.)

Congress has also recognized the need in acquiring UAS. For example, it 
added funding between fiscal years 2003 and 2005 to enable the Air 
Force to accelerate procurement of the Reaper UAS. Over those 3 years, 
Congress increased the Reaper budget over $70 million, directing the 
Air Force to procure a total of 8 additional air vehicles. Similarly, 
the Navy Fire Scout budget was increased by $17 million in fiscal year 
2006 to procure 2 additional air vehicles. In fiscal year 2003, the 
Global Hawk budget was increased by $90 million, primarily to develop 
advanced payloads for signals and imagery intelligence 
capabilities.[Footnote 1] 

Some ISR Development Programs Have Experienced Problems That Have Led 
to Cost Growth, Delays, and Additional Investments in Legacy Systems: 

Nearly all of the 13 airborne ISR programs in development that we 
reviewed have experienced some cost or schedule growth. [Footnote 2] 
Cost and schedule growth in these programs is largely the result of a 
poor business case or acquisition strategy that failed to capture 
sufficient knowledge about the product technologies and design before 
committing to the development and demonstration of a new system. 
Significant delays in the delivery of some new systems, breaking the 
investment strategy (for the new and legacy systems to be replaced) 
established at the start of these acquisition programs, have required 
DOD to make additional unplanned investments in legacy systems in order 
to keep them relevant and operational longer than planned. Delays in 
the Aerial Common Sensor (ACS) aircraft have required DOD to make 
additional unplanned investments in three Army and Navy legacy aircraft 
systems in order to keep them relevant and operational longer than 
planned. These additional investments, totaling about $900 million, 
represent opportunity costs that could have been used for other needs 
within DOD. 

Cost, Schedule, and Performance Status of Airborne ISR Programs: 

Of the 13 airborne ISR programs in development, 1 has experienced 
significant cost growth and 9 have experienced schedule delays that 
range from 2 months to 60 months. Table 3 summarizes ISR programs that 
have encountered problems either in development or as they prepared to 
begin the system development and demonstration phase of an acquisition 
program.

[End of table] 

Many of these programs began development without an executable business 
case and did not have a good acquisition strategy to capture critical 
system knowledge at the key decision milestones. Our work on best 
commercial practices has shown that before a company invests in product 
development, it should develop a sound business case--one that 
validates user requirements and determines that the concept can be 
successfully developed with existing resources--to minimize the risks 
associated with such a commitment. For DOD, an executable business case 
provides demonstrated evidence that (1) the warfighter need is valid 
and that it can best be met with the chosen concept, and (2) the 
concept can be developed and produced with proven technologies, 
existing design knowledge, and available funding and time. To implement 
the business case, programs must develop a realistic acquisition 
strategy, one that includes critical program knowledge--such as 
technology maturity, system design, and manufacturing and production 
processes--at key points in the acquisition. DOD's acquisition policy 
endorses a knowledge-based approach to acquisition and includes 
strategies to reduce technology, integration, design, manufacturing, 
and production risks.[Footnote 3] 

Global Hawk is an example of a program that failed to implement best 
practices for developing a new weapon system and encountered 
significant cost and schedule problems. It initially began with an 
incremental acquisition strategy that approached best practice 
standards for technology and design maturity. However, after 
development began the Air Force abandoned this strategy and radically 
restructured the program to develop and acquire a larger, more advanced 
aircraft that would have multimission capabilities (both signals 
intelligence and imagery intelligence sensors on the same aircraft). 
This new strategy called for concurrent technology development, design, 
test, integration, and production in a compressed schedule. As a 
result, the program has been rebaselined four times, the development 
schedule has been extended by 3 years, and the program has experienced 
a substantial contract cost overrun. Development costs alone have 
increased over 260 percent. In addition, unit costs have increased to 
the point where statutory reporting thresholds were triggered, 
requiring DOD to recertify the fundamental program need to 
Congress.[Footnote 4] 

Impact of Delays on Legacy Systems: 

The ACS and Global Hawk programs' failures to develop an executable 
acquisition strategy have resulted in significant delays in delivering 
required capabilities to the warfighter at the time overall investment 
decisions were made. These delays will have significant implications 
for legacy systems. Specifically, the services must now make difficult 
decisions about investing in legacy systems to keep them operational 
until the new systems have been developed and fielded. 

Aerial Common Sensor: 

The Army's termination of the ACS system development and demonstration 
contract could have significant cost, schedule, and performance impacts 
on three legacy airborne systems in the ISR portfolio--the Army's 
GUARDRAIL Common Sensor aircraft (GRCS) and Airborne Reconnaissance Low 
aircraft (ARL) and the Navy's EP-3 aircraft. The Army and the Navy had 
planned a phased approach to field ACS and retire the legacy systems 
from the inventory with a minimal investment in maintaining legacy 
systems. In the fiscal year 2004 budget, the Army had planned for small 
investments in GRCS and ARL because it expected to begin replacing them 
with ACS in 2009. In that same budget, the Navy's request reflected its 
plan to modify the EP-3.[Footnote 5] By the time DOD submitted its 
fiscal year 2008 budget, both services recognized the need to keep 
legacy systems capable because the ACS development contract was 
cancelled. Therefore, the budget included funding to keep these legacy 
systems operational for a longer period of time. 

Since the termination of the ACS development contract, the program has 
reverted to a technology development stage as the Army restructures the 
program. ACS is scheduled to restart system development and 
demonstration in 2009, 5 years later than the initial development 
decision. Although the Army has not established a new date for initial 
operating capacity, that date is also likely to slip by 5 years to 
fiscal year 2014. The cost to keep GRCS and ARL mission equipment 
viable and the platforms airworthy during this time is estimated to be 
$562 million between fiscal years 2008 and 2013, an increase of $550 
million over what had been previously planned. Without these 
improvements, the systems will not remain capable against modern 
threats, possibly resulting in a gap in ISR capabilities on the 
battlefield. In addition, the platforms could not continue to fly 
during this time frame without increased structural and avionic 
modifications. 

The Navy had planned to replace its EP-3 with ACS and begin fielding 
the new system in fiscal year 2012. After the Army terminated the ACS 
development contract, the Navy considered remaining part of the Army's 
development effort. However, according to Navy officials, the Chief of 
Naval Operations directed the Navy to proceed with a separate 
development effort, designated the EP-X. The Navy now plans to proceed 
with system development and demonstration in the fourth quarter of 
fiscal year 2010. The Navy has not established a date to begin fielding 
the new system, but that is not likely to take place before 2017. This 
will be a 5-year slip in retiring the oldest EP-3 systems and will make 
modifications to those systems necessary so that they can remain in the 
field until the Navy achieves full operating capacity for its EPX. The 
Navy plans to invest $823 million between fiscal years 2008 and 2013 to 
modify the EP-3, an increase of 73 percent over the $475 million that 
was previously planned. 

Table 4 summarizes the budgetary impact of the delay in developing and 
fielding ACS on the legacy systems it was to replace.

Global Hawk: 

The Air Force plans to replace the U-2 with the Global Hawk, but delays 
in the Global Hawk program have contributed to the need to keep the U- 
2 in the inventory longer than anticipated. In December 2005, the Air 
Force had planned to begin retiring the U-2 in fiscal year 2007 and 
complete the retirement by fiscal year 2012. Although the next 
configuration of the Global Hawk (with limited signals intelligence 
capability) is scheduled for delivery in fiscal year 2009, it will not 
have the same capability as the U-2. The version of the Global Hawk 
that plans to include a more robust signals intelligence capability is 
scheduled to begin deliveries in 2012. The Air Force is now developing 
a plan to fully retire the U-2s a year later, in 2013, and at a slower 
rate than the 2005 plan. There are no funds in the budget beyond fiscal 
year 2006, but Air Force officials stated they intend to fund projects 
necessary to keep the U-2 capable. Figure 1 shows the rate at which the 
Air Force had planned to retire the U-2 and the revised retirement plan 
compared to Global Hawk fielding.

Opportunities Exist for Greater Collaboration across the Services' ISR 
Programs: 

Among the ISR acquisition programs we reviewed, we found specific cases 
where the military services have successfully collaborated and achieved 
savings of time and resources. The Army estimated that for its Fire 
Scout program, buying common components with the Navy Fire Scout 
program would save $200 million in development costs alone and that 
there were greater opportunities for savings. However, we also found 
cases where more collaboration is needed to provide greater 
efficiencies and jointness in developing more affordable new systems 
and to close gaps in capabilities. These programs include the potential 
for greater collaboration between the Navy Broad Area Maritime 
Surveillance (BAMS) and the Air Force Global Hawk programs, and the Air 
Force Predator and Army Warrior programs. 

Army and Navy's Collaboration on Fire Scout Has Achieved Efficiencies: 

In 2000, the Army began developing Fire Scout, a vertical takeoff and 
landing UAS, as part of the Army's Future Combat Systems.[Footnote 6] 
At the same time, the Navy was developing its own Fire Scout program. 
Although these programs were not required to work jointly or 
collaborate, Army Fire Scout program managers contacted their 
counterparts in the Navy to determine whether efficiencies could be 
achieved through collaboration. 

Officials from the two programs met several times to share information 
on their respective aircraft's configuration, performance requirements, 
testing, support, and other issues. Initially the requirements for the 
two systems were quite different. For example, the Army's UAS had four 
rotor blades and a larger engine, while Navy's system had three rotor 
blades and a smaller engine. However, after discussions, the Navy 
officials determined that the Army's Fire Scout aircraft would meet 
their needs and decided to switch to the Army's configuration. Both 
services are buying common components, such as the air vehicle and 
flight components, under one contract. 

An Army program management official estimated that the savings to the 
Army in research and development alone would be about $200 million. As 
both programs mature, the official believes additional synergies and 
savings could be realized through contract price breaks on quantities 
and shared test assets, such as air vehicles, support equipment, and 
test components. Jointly acquiring common hardware under one contract 
will also reduce procurement administrative lead time and permit common 
design, tooling, and testing. Finally, future payload development, such 
as communications, sensors, and data links, could be procured jointly. 

Collaboration on Broad Area Maritime Surveillance Could Yield Similar 
Efficiencies: 

In 2000, the Navy identified a mission need for a broad area maritime 
and littoral ISR capability and on the basis of a 2002 analysis of 
alternatives, the Navy decided to pursue a manned platform, MMA, with 
an unmanned adjunct, BAMS. The Navy subsequently performed an analysis 
of alternatives for the BAMS program, which identified several 
potential alternatives; foremost among them was the Global Hawk system. 
As a risk reduction effort, the Navy funded the Global Hawk Maritime 
Demonstration program in 2003. Working through the existing Air Force 
contract, the Navy procured two Global Hawk UAS and associated ground 
controls and equipment.[Footnote 7] The demonstration program was 
expected to leverage the existing Global Hawk system to develop 
tactics, training, and techniques for maritime mission applications. 

The BAMS program is at a critical juncture. It released a request for 
proposals in February 2007 and plans to proceed with system development 
and demonstration in October 2007. If the Global Hawk (or another 
existing system like the Air Force Reaper) is selected, there are 
opportunities for the Navy to work with the Air Force and take 
advantage of its knowledge on the existing platform. Through 
collaboration, the Navy could leverage knowledge early in the 
acquisition process and avoid or reduce costs for design, new tooling, 
and manufacturing, and streamline contracting and acquisition 
processes. 

Collaboration Slow to Occur on Warrior and Predator: 

Despite similarities in the Predator and Warrior programs, the Air 
Force and Army have repeatedly resisted collaboration. The Air Force’s 
Predator is a legacy program that has been operational since 1995. Its 
persistent surveillance/full motion video capability continues to be a 
valued asset to the warfighter. However, when the Army began in 2001 to 
define requirements for the Warrior, a system similar to the Predator, 
it did not fully explore potential synergies and efficiencies with the 
Air Force program. The Army did not perform an analysis of alternatives 
to explore other options to a new system; it cited the urgent need of 
battlefield commanders for the capability. In lieu of an analysis of 
alternatives, the Army conducted a full and open competition and 
awarded the contract to the same contractor producing the Predator. 
Although the requirements for the Warrior were subsequently validated, 
reviewing officials from the Air Force and the Joint Staff raised 
concerns about duplication of an existing capability. 

Both Congress and the Office of the Secretary of Defense (OSD) have 
raised concerns about duplication between the two systems. During 
question and answer sessions at various Congressional hearings, members 
of Congress sought an explanation of the need for both systems. In 
addition, OSD commissioned an industrial capabilities study to assess 
whether the contractor for the Predator and the Warrior had sufficient 
capacity to produce both systems at the same time. While the study did 
not find any major production constraints, it concluded that the two 
systems were 80 percent common. In January 2006, the Army and Air Force 
agreed to consider cooperating on the acquisition of the two systems. 
However, progress to date in implementing the agreement has been 
limited due partly to differences in operating concepts for the two 
services. Unlike the Air Force, the Army does not use rated pilots; it 
relies on technicians and automated takeoff and landing equipment. In 
addition, the Army uses direct-line-of-sight communications, while the 
Air Force uses beyond-line-of-sight communications. Despite these 
inherent differences, there are still many areas available for 
collaboration, including airframes, ground stations, and 
equipment.[Footnote 8] 

The Air Force and the Army are currently working to identify program 
synergies in a three-phased approach: 

* First, the Air Force will acquire and test two of the more modern 
Warrior airframes. 

* Second, the two services will compare their requirements for ground 
control stations and automated takeoff and landing. 

* Finally, the Army and Air Force plan to compare concepts of operation 
and training requirements for additional synergies. 

To date, the Army has coordinated the proposed approach through the 
Vice Chief of Staff level, but the agreement has not yet been approved 
by the Department of Army. The Air Force is still working to resolve 
comments and concerns at lower organizational levels. In the interim, 
the Air Force has greatly increased the number of Predator aircraft it 
plans to procure annually to meet the high demand from the warfighter 
for this capability, increased in part by the war on terror. Instead of 
buying 7 Predator aircraft per year, as the Air Force had initially 
planned, it now plans to buy 24 aircraft in both 2007 and 2008, as well 
as another 22 aircraft as stated in the fiscal year 2007 supplemental 
request. In total, the Air Force plans to buy 160 Predators between 
fiscal years 2008 and 2013.[Footnote 9] 

The Air Force is currently seeking authority to become the executive 
agent for UAS. This would allow it to have decision authority over 
these type of medium and high altitude UAS. As a part of its efforts, 
in March 2007 the Air Force began a comprehensive study of all existing 
and planned (airborne and space-based) ISR systems. As executive agent 
the Air Force believes it could improve the allocation of UAS, avoid 
duplication of separate service acquisition efforts by centralizing 
procurement, standardize downlinks, and control burgeoning bandwidth 
requirements.[Footnote 10] However, the Air Force still intends to 
procure two Warriors for testing, but details of a potential 
collaboration with the Army remain uncertain. 

Timing on the Army and Air Force's collaboration is critical: The 
longer the services wait to collaborate, the lower the return. The 
opportunity to achieve synergies in design, manufacturing, and support 
will greatly diminish as the Warrior matures and more and more 
Predators are added to the inventory. 

DOD Efforts to Improve Collaboration: 

The environment in which DOD operates has changed significantly since 
2001. In recognition of this, the department's 2006 Quadrennial Defense 
Review described a vision that focuses on defining ISR needs based on 
the type of intelligence or sensor rather than on the platform that 
carried the sensor. Specifically, the department's vision for ISR is to 
establish persistent surveillance over the battlefield and define ISR 
sensor needs in terms of the type of intelligence needed rather than 
the air, surface, or space platform in which they operate. Accordingly, 
the department initiated a number of studies aimed at reviewing ISR 
requirements and developing solutions either through new development 
programs or changes in current systems (see app III for a brief 
description of these studies). While most of the studies have been 
completed, as of March 2007, DOD had released the results of only one-
-the Joint ISR study, which validated the requirement and confirmed the 
continued need for the Army's ACS program. The results of the other 
studies have not been released outside of DOD, but according to DOD 
officials, several were briefed to senior leadership within OSD and the 
Joint Staff. 

One study DOD is undertaking has some promise to better manage the 
requirements for future ISR capabilities across DOD by applying a joint 
capability portfolio management concept to acquisition planning. This 
pilot program is a test case to enable DOD to develop and manage ISR 
capabilities across the entire department--rather than by military 
service or individual program--and by doing so, to improve the 
interoperability of future capabilities, minimize capability 
redundancies and gaps, and maximize capability effectiveness. However, 
the portfolios are largely advisory and will, as a first step, provide 
input to decisions made through the acquisition and budgeting process. 
At this point the capability portfolio managers have not been given 
direct authority to manage fiscal resources and make investment 
decisions. Without portfolios in which managers have authority and 
control over resources, DOD is at risk of continuing to develop and 
acquire systems in a stovepiped manner, and of not knowing whether its 
systems are being developed within available resources.[Footnote 11] 

In addition to the various studies previously initiated, two more 
studies were recently commissioned in February and March of 2007. The 
Under Secretary of Defense for Acquisition, Technology, and Logistics 
requested that the Defense Science Board establish a task force to 
assess whether current and planned ISR systems provide sufficient 
support for U.S. military forces. The objectives of the study are to 
(1) determine what improvements are needed for ISR systems, (2) examine 
the balance and mix of sensors to identify gaps and redundancies, and 
(3) identify vulnerabilities, potential problems, and consistency with 
DOD network centered strategy. The Secretary also asked the task force 
to review the findings of previous studies as part of the assessment. 
In addition, the Chief of Staff of the Air Force recently began a 
comprehensive study of all existing and planned airborne and space- 
based ISR systems to determine their efficiencies and inefficiencies. 
The effort includes developing a plan to increase interdependence of 
medium-and high-altitude UAS and establish the Air Force as the 
executive agent for all UAS in those regimes. A specific date for 
reporting the results of these two studies has not been established. 

Conclusions: 

Many ISR systems suffer from the same cost, schedule, and performance 
problems as other DOD acquisition programs by failing to establish a 
good business case or capture critical product knowledge at key 
decision points before moving forward in the acquisition process. In 
some cases, the outcomes have been costly as legacy systems, once 
planned for an earlier retirement, must now stay in the inventory, 
requiring additional unplanned investments to keep them relevant and 
operationally ready until a new capability can be fielded. The funds 
spent to keep these systems viable represent opportunity costs that 
could have been used for other DOD priorities. GAO has made numerous 
recommendations in recent years to improve the acquisition process and 
get more predictable outcomes in major acquisition programs and these 
would apply to the development of ISR systems. 

Ideally, because of the warfighter's universal needs for ISR 
information, determining requirements and planning for ISR acquisition 
programs should be based on a joint process that occurs at the 
enterprise level in DOD to ensure economies and efficiencies based on 
effective joint solutions to the maximum extent possible. DOD has 
various studies in process that appear to have this as a goal for ISR, 
but for now it is not routinely happening. The portfolio management 
pilot program could potentially improve how DOD determines requirements 
and sets up new acquisition programs for ISR capabilities. However, the 
portfolios are largely advisory and the managers have no direct 
authority to make investment decisions. Without authority and control 
over investments there is the risk that nothing will change. At best 
for now, there are some acquisition programs that through their own 
initiative have garnered benefits from collaborative efforts. Others 
still choose a stovepiped approach to provide a unique system for the 
specific military service's needs. 

Recommendations for Executive Action: 

While DOD has numerous ISR studies, either recently completed or 
ongoing, there have been no substantive actions recently implemented to 
gain greater jointness in ISR acquisition programs. Therefore, we 
recommend that DOD: 

1. Develop and implement an integrated enterprise-level investment 
strategy approach that is based on a joint assessment of warfighting 
needs and a full set of potential and viable alternative solutions, 
considering cross-service solutions including new acquisitions and 
modifications to legacy systems within realistic and affordable budget 
projections for DOD. This strategy should draw on the results of 
ongoing studies, like the portfolio management pilot program, but 
should include the necessary authority and controls needed to ensure a 
single point of accountability for resource decisions. 

2. Report to the defense committees by August 1, 2007, the results of 
the ISR studies and identify the specific plans and actions needed and 
intended to make joint acquisition decisions in ISR programs and 
improve the way it plans, buys, organizes, manages, and executes its 
ISR acquisition programs and operations. 

Agency Comments and Our Evaluation: 

DOD provided us with written comments on a draft of this report. The 
comments appear in appendix IV. 

DOD agreed that it can report the interim status of ongoing ISR studies 
to the committees by August 1, 2007, but suggested that delaying this 
reporting until December 31, 2007, would allow the department to 
include the results of two pertinent studies now ongoing. We believe a 
full reporting in December 2007 would be useful if it includes DOD’s 
detailed plans on how it will achieve an integrated enterprise-level 
investment strategy for ISR including planned changes to policy and 
guidance, organization, and points of authority and responsibility. 
However, we believe an interim reporting to the committees on the 
results and planned outcomes from completed studies should be provided 
to the committees by August 2007. 

DOD agreed with our recommendation to develop and implement an 
integrated enterprise-level investment strategy for ISR and stated that 
it thought this process was well under way in existing department 
processes. However, it non-concurred with having a single point of 
authority and control for ISR resource decisions and provided a number 
of arguments as to why sufficient information was not included in the 
report to support this specific part of the recommendation. We continue 
to believe that our recommendation for an enterprise-level investment 
strategy with a single point of accountability for resources decisions 
is necessary to maximize to the full extent efficiency and 
effectiveness in acquiring major acquisition systems. The Defense 
Science Board Summer Study on Transformation reported in February 2006 
came to similar conclusions: that the Secretary of Defense should 
assemble a small direct-reporting cell to create and maintain a metric-
based, multiyear plan that specifies what is to be done, when, with 
what resources, and with what capability output.[Footnote 12] It 
concluded the Under Secretary of Defense for Acquisition, Technology, 
and Logistics needs authority over architectures, resources, and 
personnel. Our other review efforts of the acquisition and requirements 
processes continue to show that DOD has not sufficiently improved the 
process to ensure cross-service redundancies are reduced or eliminated 
where possible. Therefore, without this single point of authority, 
limited defense resources are still not optimally used to develop and 
produce weapon systems. Our comments below address the specific 
arguments presented in DOD’s response to this report. 

We believe that many of the ongoing initiatives to achieve a greater 
integrated investment strategy approach for ISR are steps in the right 
direction but are concerned that they will not go far enough to address 
the problems that have occurred in DOD acquisitions for some time now. 
DOD suggests that the Joint Capabilities Integration and Development 
System (JCIDS) has been implemented to identify joint warfighting 
capabilities. We agree that the JCIDS emphasizes a more joint approach 
to identifying and prioritizing warfighting needs. However, as reported 
in our March 30, 2007 report, Best Practices: An Integrated Portfolio 
Management Approach to Weapon System Investments Could Improve DOD’s 
Acquisition Outcomes, this system is still not working as planned. 
Despite the provisions of JCIDS, needs continue to be based on 
investment decision-making processes that do not function together to 
ensure DOD pursues needs that are not redundant. The Warrior decision 
is an example where the service chose to ignore the recommendations of 
the Joint Requirements Oversight Council and proceeded with a unique 
program. 

DOD stated that its Portfolio Management Experiment supports this 
enterprise-level strategy, but it is still a pilot program and actual 
changes to the processes have not been identified to show how it will 
ensure more responsible and joint decision making for major acquisition 
programs. As pointed out in the report, while this seems like a good 
first step, portfolios are largely advisory and managers have not been 
given direct authority to manage fiscal resources and make investment 
decisions. Without this authority, DOD continues to risk stovepiped 
solutions that may overlap and not be affordable within available 
resources. Furthermore, it seems within the last few years the real 
input from DOD leadership comes at the end of the year, right before 
the budget is supposed to go to Congress. In December each year a 
Program Budget document is issued by the Office of the Secretary of 
Defense that has included radical changes to major acquisition programs 
but without the transparency as to the detailed analysis and integrated 
investment planning that should have taken place to make these major 
investment decisions. 

In its response, DOD also states that a number of successes have 
occurred within the Unmanned Aerial Systems portfolio managed by the 
Office of Under Secretary of Defense for Acquisition, Technology, and 
Logistics. While there may be some successful UAS programs, there are 
also examples of large, important programs that have significantly 
exceeded cost estimates and delivery dates. We believe that having a 
UAS portfolio is contrary to the direction of the Quadrennial Defense 
Review to get away from “platform”-based decisions and move toward 
“sensor”-based decisions. The Battlespace Awareness Functional 
Capabilities Board, as part of the JCIDS process, seems to be a more 
representative grouping of ISR programs than the UAS portfolio. We 
believe if properly organized based more on “sensor” requirements, then 
it would not be necessary to have both for ISR investment decision 
making. 

DOD states that we did not consider the department’s ongoing efforts to 
develop UAS and ISR Roadmaps that represent, according to them, 
enterprise-level strategies. While we did not review these as part of 
this review, GAO has ongoing work under a different engagement that is 
looking at the ISR Roadmap. The initial conclusions from that review 
were presented to the House Armed Services Subcommittee on Air and Land 
Forces in testimony on April 19, 2007.[Footnote 13] GAO testified that 
the ISR Roadmap was a noteworthy step in examining ISR capabilities but 
it does not represent a comprehensive vision for the ISR enterprise or 
define strategy to guide future investments. Furthermore, the ISR 
Roadmap is managed by the Office of the Under Secretary of Defense for 
Intelligence, while the UAS Roadmap is managed by the Office of the 
Under Secretary of Defense for Acquisition, Technology, and Logistics. 
This difference emphasizes the need for a single point for ISR 
investment decisions within OSD. 

Finally, DOD states that the report does not recognize ground component 
requirements and operating concepts for multiple joint missions and 
that it did not recognize the benefits of acquisition programs with 
unique requirements or the benefits of competition. We believe the 
report, as it relates to the decision to buy a unique platform for the 
Warrior, did recognize the difference in how the two services planned 
to operate the platforms. However, we do not believe that it 
necessarily excuses DOD to buy two different platforms to satisfy the 
warfighter’s expressed ISR requirement. Furthermore, we believe it has 
been the unique stovepiped solutions of the military services that have 
over time created unnecessary duplication and inefficient use of 
limited defense funding. As to competition, GAO has consistently 
expressed its belief that with proper controls and oversight 
competition is beneficial to price, reliability, performance, and 
contractor responsiveness in buying major weapon systems.

Appendix I: Objectives, Scope, and Methodology: 

This report examines the Department of Defense (DOD) development and 
acquisition of airborne intelligence, surveillance, and reconnaissance 
(ISR) systems. The primary focus of this work is to identify practices 
and policies that lead to successful fielding of weapon systems to the 
warfighter at the right time and for the right price. Specifically, our 
objectives were to (1) evaluate various ISR platforms for potential 
synergies and assess their cost and schedule status and the impact of 
any increases or delays on legacy systems; and (2) evaluate the 
effectiveness of ISR investment decisions. Our work was conducted 
between June 2006 and April 2007 and in accordance with generally 
accepted government auditing standards. 

We selected 20 major airborne ISR programs in technology or systems 
development, already fielded but undergoing significant upgrade, or 
operating in the field but due to be replaced by a system in 
development; and one space-based program in technology 
development.[Footnote 14] We considered a program in development to be 
major if DOD designated it as a major defense acquisition program or 
would be likely do so at Milestone B.[Footnote 15] We considered 
systems already operating in the field as major if they played a role 
in current operations. 

For the systems we selected, we obtained information on current or 
projected operational capabilities, acquisition plans, cost estimates, 
schedules, and estimated budgets. We analyzed the data to determine 
whether pairs of similar systems shared common operating concepts, 
capabilities, physical configurations, or primary contractors. We 
reviewed acquisition plans for programs in development to determine 
whether they had established sound business cases or if not, where the 
business case was weak. We reviewed cost and schedule estimates to 
determine whether they had increased, and where possible, identified 
reasons for the increases. For systems in development that experienced 
a schedule delay, we determined whether the delay had an impact on the 
legacy system to be replaced and where possible, determined the cost or 
capability impact of the delay. We assessed the reliability and 
validity of agency-official-provided and third party data by discussing 
the data with officials from multiple agencies at varying levels of 
responsibility. We also discussed the results of our reviews and 
analyses with program office officials; Army, Navy, and Air Force 
acquisition and requirements officials; the office of the Under 
Secretary of Defense for Intelligence; and the office of the Joint 
Chief of Staff for Intelligence.

Appendix II: System Descriptions: 

Aerial Common Sensor: 

The Army is planning to develop the Aerial Common Sensor (ACS) as an 
airborne ISR and target acquisition system and is designing it to 
provide timely intelligence data on threat forces to the land component 
commander. The platform will be a large, piloted business jet and will 
carry a suite of sensors to collect information on electronics and 
communications signals, optical and infrared images, measures and 
signatures, and synthetic aperture radar (SAR) images. Four onboard 
intelligence analysts will operate the mission equipment, but with the 
appropriate connectivity, the system can perform its mission with just 
the flight crew. The ACS will replace the Guardrail Common Sensor and 
the Airborne Reconnaissance Low airborne systems and will coexist with 
current systems until it is phased in and current systems retire. The 
Army has not established a date for initial operating capacity. ACS was 
to have replaced the Navy EP-3 as well. However, the Navy recently 
decided to pursue its own development program and expects to enter 
system development in 2010. 

Airborne Reconnaissance Low: 

Airborne Reconnaissance Low (ARL) is composed of communications 
intelligence and imagery intelligence sensors and onboard operators in 
a piloted aircraft. The current inventory includes two configurations; 
one with a complete communications sensor package capable of 
intercepting and locating radio emissions and providing reports to 
appropriate commanders and intelligence-processing centers on the 
ground. The more capable version combines communications and electro- 
optical (EO) sensors, and SAR with moving target indicator onto one 
aircraft. The ARL will eventually be replaced by ACS. 

Airborne Signals Intelligence Payload: 

The Airborne Signals Intelligence Payload (ASIP) is a signals 
intelligence (SIGINT) sensor being developed for use on multiple Air 
Force platforms. It is a part of Air Force efforts to modernize its 
SIGINT processes by developing an Air Force-wide capability for 
performing SIGINT. ASIP sensors will be developed for use on the legacy 
U-2 and Rivet Joint manned aircraft. It will also be used on legacy and 
developmental unmanned aerial system (UAS) to include the MQ-1/MQ-9 
(Predator/ Reaper) and RQ-4B Global Hawk. The details about its 
capabilities are classified. 

Broad Area Maritime Surveillance Aircraft System: 

The Broad Area Maritime Surveillance (BAMS) UAS is scheduled to begin 
systems development in October 2007. The BAMS system will be land-based 
and provide a high-altitude, persistent ISR capability to the fleet and 
joint forces commander. BAMS will conduct continuous maritime and 
littoral surveillance of targets. As part of the Navy's maritime patrol 
and reconnaissance force, it will operate independently or in 
conjunction with the Multi-mission Maritime Aircraft (MMA) and EP-3/EPX 
signals intelligence platform. Because the BAMS has not yet begun 
system development, vehicle design and sensor payload decisions have 
not been finalized, but will include active imaging radar, passive 
optical imaging, and limited signals collection capability. Its 
projected initial operational capability is 2013. 

E-10A: 

The E-10A Program originally consisted of three primary elements: the 
aircraft, the radar, and the battle management command and control 
system. The aircraft proposed for the E-1OA is the Boeing 767 jet 
aircraft. The radar is to be the Multi-platform Radar Technology 
Insertion Program, which uses a SAR to provide a focused Air-Moving 
Target Indicator (AMTI) and for Ground Moving Target Indicator (GMTI). 
The program has been reduced from a technology development program to a 
demonstration effort. The demonstration effort is focused on assessing 
the newer radar, which will also be used on the Global Hawk UAS. 
However, the Air Force recently canceled the demonstration effort. 

EP-3: 

The EP-3E Airborne Reconnaissance Integrated Electronics System (ARIES) 
II is the Navy's only land-based SIGINT reconnaissance aircraft. It is 
a legacy aircraft based on the Navy's Orion P-3 airframe and provides 
fleet and theater commanders worldwide with near-real-time tactical 
SIGINT. It uses sensitive receivers and high-gain dish antennas to 
perform its mission. The Navy had planned to replace this aircraft with 
the Army ACS because the EP-3 airframe is aging and has a limited life 
span. Drawdown of the EP-3E aircraft was scheduled to begin in the 2012 
time frame but may be extended. Delays in ACS development contributed 
to the Navy's recent decision to pursue its own replacement for the EP- 
3. 

EPX: 

The EPX is the Navy's replacement for its aging EP-3. In late summer 
2006, after a study on joint ISR requirements had been completed, the 
Navy and Army concluded that there were significant requirements 
differences between the two services. As a result, the Chief of Naval 
Operations directed the Navy to recapitalize the EP-3 to provide multi- 
intelligence capability. While requirements for the EPX have not been 
fully established, it will be a multi-intelligence platform and will 
include communications and electronics intelligence capability, optics, 
and radar. EPX is part of the maritime patrol and MMA and BAMS. 

Fire Scout (Army): 

The Army Fire Scout is being developed as one of the UAS within the 
Future Combat Systems. As part of this system of systems, the Fire 
Scout is designed to support air-ground operations and reconnaissance, 
surveillance, and target acquisition missions. It will employ SAR with 
moving target indicator, EO sensors and a laser rangefinder/designator, 
a tactical signals intelligence package, and the joint tactical radio 
system communications suite. The Fire Scout is designed to take off and 
land in unimproved areas to directly support brigade combat team 
operations. Its initial operating capability is tied to the Future 
Combat Systems, which is planned for December 2014. 

Fire Scout (Navy): 

The Navy Fire Scout, or the vertical takeoff and landing unmanned 
aerial vehicle system, (VTUAV), entered systems development in February 
2000. The Fire Scout is designed to provide ISR as well as targeting 
data and damage assessments to tactical users. It is capable of 
autonomous vertical takeoff and landing on aircraft carriers as well as 
unprepared landing zones. The Fire Scout includes EO/IR sensors, a 
laser designator system, and a common automatic recovery system. The 
modular payload approach also includes the tactical control system, 
tactical common datalink, and a mine detection system. Its initial 
operating capability is planned for October 2008. 

Joint Surveillance, Target Attack, and Radar System: 

Joint Surveillance, Target Attack, and Radar System (STARS) is a joint 
Air Force and Army wide area surveillance attack radar system designed 
to detect, track, and classify and support the attack of moving and 
stationary targets. Joint STARS is a legacy platform first use being in 
the 1991 Gulf War. It has been used extensively in support of 
Operations Enduring and Iraqi Freedom. The Joint STARS fleet of 
aircraft is currently being modified with new communication and 
navigation equipment, and the Air Force is developing advanced mission 
capabilities and identifying low-cost emerging technologies for future 
use. In addition, the Air Force intends to replace Joint STARS engines 
to make the platform more reliable and reduce operating and support 
costs. Finally, the Air Force had originally intended to place Multi- 
platform Radar Technology Insertion Program (MP-RTIP) on Joint STARS 
but decided not to when it chose to go forward with the E-10A, which 
was subsequently canceled. 

Global Hawk: 

The Global Hawk is a high-altitude, long-endurance UAS designed to 
provide near-real-time high-resolution ISR imagery. It employs a SAR, 
GMTI, and EO/IR sensors. After a successful technology demonstration, 
the Global Hawk entered development and limited production in March 
2001. Production of the initial seven (RQ-4A) aircraft is complete. The 
larger, more capable version (RQ-4B) includes an advanced signals 
intelligence payload and improved radar technologies. Initial 
operational capability is planned for September 2007. 

GUARDRAIL Common Sensor: 

GUARDRAIL Common Sensor (GRCS) is an airborne signals intelligence 
collection location and exploitation system in the current inventory 
that provides near-real-time signals intelligence and targeting 
information to tactical commanders. The system integrates a 
communications intelligence sensor and precision geolocation of 
signals. The platform is a small, piloted aircraft with no onboard 
analysts. The Army plans on eventually replacing GRCS with the ACS. 

Multi-mission Maritime Aircraft: 

The Navy's MMA is part of the broad area maritime family of systems. 
The MMA was initially planned to interoperate with the BAMS UAS and the 
ACS. The MMA is intended to replace the Navy's P-3C Orion system. Its 
primary role will be that of anti-submarine and anti-surface warfare, 
and it will have some ISR capability. The Navy plans for the aircraft 
to achieve initial operational capability in 2013. 

Multi-platform Radar Technology Insertion Program: 

The MP-RTIP is a family of scalable, advanced radars that are being 
developed for the RQ-4B Global Hawk and the E-10A. The Air Force funded 
the sensor development under the E-10A budget line as a separate item. 
The radar is currently in system development and demonstration. 
However, in February 2007, the Air Force removed funding for the E-10A 
radar development program starting in fiscal year 2008. The Air Force 
still intends to develop the radar for the Global Hawk and begin 
fielding the sensor by 2011. 

Predator: 

The Predator is a medium-altitude long-endurance UAS. The Predator 
began as an advanced concept technology demonstration program and has 
been operational since 1995. Originally designed as a persistent ISR 
platform, it was modified in 2001 to carry two Hellfire missiles. The 
Predator employs EO/IR sensors, laser designator, day/night cameras 
that produce full motion video of the battlefield, and can be 
configured to carry SAR. Used as an armed reconnaissance system, the 
Predator also has a multi-spectral targeting system with Hellfire 
missile targeting capability. The Air Force has begun an effort to 
develop and integrate signals intelligence capability on the Predator. 
To accelerate this effort, the Air Force increased this budget by a 
factor of almost 6 in fiscal year 2008. 

Reaper: 

The Reaper (formerly Predator B) is a multirole medium- to high-
altitude endurance UAS. Its primary mission is a persistent hunter-
killer for small ground mobile or fixed targets. Its secondary mission 
is to gather ISR data. It will use EO/IR sensors, laser 
rangefinder/designator, and SAR, and will carry ordnance such as the 
Joint Direct Attack Munitions and Hellfire missiles. The Reaper entered 
systems development in February 2004. Its initial operating capability 
is planned for 2009. The Air Force has begun to examine the feasibility 
of incorporating signals intelligence capability on the Reaper. 

Rivet Joint: 

Rivet Joint (RJ) is a reconnaissance aircraft in the current inventory 
that supports theater-and national-level consumers with near-real-time 
on-scene intelligence collection, analysis, and dissemination 
capabilities. The aircraft is an extensively modified C-135 with a 
suite of onboard sensors, which allows the mission crew to detect, 
identify, and geolocate signals throughout the electromagnetic 
spectrum. The mission crew can then forward gathered information in a 
variety of formats to a wide range of consumers via the system's 
extensive communications suite. The interior seats 34 people, including 
the cockpit crew, electronic warfare officers, intelligence operators, 
and in-flight maintenance technicians. The first versions of the system 
were deployed in 1964, but have undergone extensive upgrades to both 
the platform and mission equipment. The Air Force does not have any 
plans to replace the system. 

Space Radar: 

Space Radar (SR) is an Air Force-led, joint DOD and intelligence 
community program to develop a satellite to find, identify, and monitor 
moving or stationary targets under all weather conditions on a nearly 
continuous basis across large swaths of the earth's surface. As 
envisioned, SR would generate volumes of radar imagery for 
transmissions to ground-, ship-, air-, and space-based systems. Initial 
capability is planned for 2017. 

U-2: 

The U-2 provides continuous day-and-night, high-altitude, all-weather 
surveillance and reconnaissance in direct support of US and allied 
ground forces. It is a single-engine and single-seat ISR aircraft. The 
U-2 is capable of collecting multisensor, photo, EO/IR, and radar 
imagery as well as collecting SIGINT data. It can downlink all data 
except wet film. The Air Force proposed to begin retiring the U-2 in 
2007. However, Congress disagreed with the decision and prevented 
retirement in 2007. Congress also directed the Air Force to first 
certify that the capability was no longer required. In March 2007, the 
Air Force revised the schedule from removing the U-2 from the inventory 
and proposes doing so at a slower rate than before beginning in fiscal 
year 2008. The Air Force is not requesting funding for the U-2 past 
2007, but it is not clear whether the Air Force has provided the 
certification that Congress requested. 

Warrior: 

The extended range, multipurpose Warrior UAS began systems development 
in April 2005. It will operate with manned aviation assets such as the 
Apache helicopter and perform missions including reconnaissance, 
surveillance, and target acquisition/attack. It is being developed to 
satisfy the Army's requirement for a UAS that is dedicated to the 
direct operational control of its field commanders. The Warrior is 
designed with an automatic takeoff and landing system, full motion 
video capability, tactical signals intelligence payload, multirole 
tactical common data link, EO sensors, SAR/ moving target indicator, 
Ethernet communications capability, and redundant avionics. Its initial 
operational capability is planned for 2010.

Appendix III: ISR Studies Under Way or Recently Completed: 

Program Decision Memorandum III, dated December 2005 directed that 
several studies be undertaken.[Footnote 16] Those studies included the 
following. 

Joint ISR Replacement Study: 

The Army and Navy, in coordination with the Air Force, Joint Staff, 
Under Secretary of Defense for Policy, Under Secretary of Defense for 
Intelligence (USD(I)) and Program Analysis and Evaluation (PA&E), were 
directed to conduct a study of joint multi-intelligence airborne ISR 
needs, focusing on trade-offs among manned and unmanned airborne 
platforms and how those trade-offs translate into requirements for 
recapitalizing the Army, Navy, and Air Force legacy systems. The 
participants were directed to identify any resources in addition to the 
fiscal year 2006 President's budget program of record to sustain the 
Army and Navy aircraft until they can be replaced. The study was 
completed in late summer of 2006 and concluded that the requirements 
for the ACS were still valid. 

U-2 Retirement Study: 

The Strategic Command, in coordination with the Air Force; Navy; Under 
Secretary of Defense for Acquisition, Technology and Logistics 
(USD(AT&L)); USD(I); and PA&E were directed to review the Air Force's 
Global Hawk acquisition and U-2 retirement plan and determine if high- 
attitude, long-endurance, multi-intelligence ISR requirements will be 
satisfied during the transition. The findings were briefed within OSD 
in early fall 2006. 

Airborne ISR Requirements: 

USD(I), in conjunction with the Joint Staff, services, and PA&E was 
directed to develop a methodology to migrate to a capability-centric 
focus, instead of a platform-centric focus, for determining combatant 
commander and joint task force airborne ISR requirements. Results were 
briefed within OSD in early fall 2006. 

These studies were recently commissioned: 

Optimization of ISR Capabilities: 

On March 5, 2007, the Air Force Chief of Staff announced the start of a 
comprehensive study of all existing and planned ISR systems--both 
airborne and spaced-based--to consider the efficiencies and 
inefficiencies in the theater and global warfighting templates. As part 
of this broad effort, he advocated that the Air Force immediately 
become the executive agent for medium-and high-altitude UAS. The 
expected benefits from the study and executive agent concept include 
improving distribution of intelligence assets across all theaters and 
components, avoiding duplication of acquisition efforts, standardizing 
UAS operations and downlinks, and controlling ballooning bandwidth 
requirements. The results of the study will include a comprehensive 
plan to optimize ISR capabilities, due in late April 2007. 

Task Force on Integrating Sensor-Collected Intelligence: 

In February 2007, the Under Secretary of Defense for Acquisition, 
Technology and Logistics requested that the Defense Science Board 
establish a task force to assess whether current and planned ISR 
systems provide sufficient support for U.S. military forces.[Footnote 
17] The primary objective is to determine what improvements are needed 
in carrying out the tasks associated with ISR systems. A second 
objective is to examine the mix and balance of ISR sensors to identify 
gaps and redundancies. The task force was also asked to examine current 
and planned systems for vulnerabilities, new opportunities and 
potential problems, and consistency with department strategy for 
networked operations. Finally, the memorandum also asked the task force 
to review the results of a number of studies, initiated by OSD and 
completed in the fall of 2006, following the completion of the 2006 
Quadrennial Defense Review. Several of these studies are summarized in 
this appendix. The tasking memorandum did not include time frames for 
completion of the study or for reporting the results.

Appendix IV: Comments from the Department of Defense: 

Office Of The Assistant Secretary Of Defense: 
6000 Defense Pentagon: 
Washington, DC 20301-6000: 
Networks And Information Integration: 

Mr. Michael J. Sullivan: 
Director, Acquisition and Sourcing Management: 
U.S. Government Accountability Office: 
441 G. Street NW: 
Washington DC 20548: 

Dear Mr. Sullivan: 

Thank you for the opportunity to comment on draft report "Defense 
Acquisitions: Greater Synergies Possible for DoD's Intelligence, 
Surveillance and Reconnaissance Systems" (GAO-07-578) dated April 5, 
2007. 

The Department agrees with the first recommendation to develop and 
implement an integrated enterprise-level investment strategy, but 
believes this process is well underway in existing Department 
processes. The Department non-concurs that the GAO has provided 
sufficient analysis and evidence to recommend a single point of 
authority and controls for ISR resource decisions and does not agree 
with that portion of the recommendation. 

The Department agrees that it can report interim status on the progress 
of the ISR Portfolio Management Pilot program to the committees by 
August 1, 2007. There are two pertinent efforts, "Optimization of ISR 
Capabilities" and "Task Force on Integrating Sensor Collected 
Intelligence," that will not complete work in time to provide input to 
the defense committees. The Department recommends a suspense date of 
December 31, 2007 to permit integration of study findings. 

It is unfortunate that an exit brief with the Department did not occur 
prior to release of this draft report. The Department strives to be 
transparent when working with the GAO and would like the GAO to ensure 
that an exit interview takes place for any future reports. 

Sincerely, 

Signed by: 

John R. Landon: 
Deputy Assistant Secretary of Defense (C3ISR & IT Acquisition): 

Enclosures: 

1. DoD Factual Comments: 

2. DoD Response to Recommendations: 

DoD Response to Recommendations From GAO Draft Report (Apr 5, 2007) GAO 
CODE 120559/GAO-07-578 "Defense Acquisitions: Greater Synergies 
Possible for DoD's Intelligence, Surveillance and Reconnaissance 
Systems" 

Recommendation 1: Develop and implement an integrated enterprise-level 
investment strategy approach that is based on a joint assessment of war-
fighting needs and a full set of potential and viable alternative 
solutions, considering cross-service solutions including new 
acquisitions and modifications to legacy systems within realistic and 
affordable budget projections for DOD. This strategy should draw on the 
results of ongoing studies, like the portfolio management pilot 
program, but should include the necessary authority and controls needed 
to ensure a single point of accountability for resource decisions. 

Response To Recommendation 1: The Department agrees with your 
recommendation to develop and implement an integrated enterprise-level 
investment strategy, but believes this process is well underway in 
existing DoD processes. However, the Department does not believe that 
GAO has provided sufficient analysis and evidence to support the 
recommendation to establish a single point of accountability for 
resource decisions. Specifically, 

The Department agrees that integrating an ISR enterprise level 
investment strategy based on a Joint assessment and ongoing studies is 
critical, but this work is already underway as noted in the GAO report, 
and OSD makes portfolio adjustments as necessary through Program Budget 
Decision and Program Decision Memorandum actions. 

* The Department's current Joint Capabilities Integration and 
Development System (JCIDS) process has been implemented to identify 
joint war- fighting capabilities. 

- The draft report does not offer observations regarding this process. 

* The Department's Capability Portfolio Management Experiment supports 
this approach in that: 

- It emphasizes resource decisions based on trade-offs within a given 
portfolio, as determined by the OSD portfolio manager. 

- Portfolio managers review capabilities across their functional 
enterprise, prioritize these capabilities according to war-fighter 
needs, and recommend to Department leadership key trade-offs-within the 
portfolio, not within each organization, which would allow the 
effective use of resources. 

- The process to accomplish portfolio realignment is through OSD 
decision memorandum; there is no intent to delegate this authority to a 
Service or other government agency. 

The Office of the Undersecretary of Defense for Acquisition, 
Technology, and Logistics (OUSD AT&L) has been very successful managing 
unmanned aerial system (UAS) development and acquisition with this 
portfolio model. With support from the Military Services, the 
Department has coordinated development and procurement of several 
Military Service specific UAS programs to meet joint Military Service 
requirements, including Raven B (Army, Marine Corps, Air Force, and 
Special Operations Command); Shadow (Army and Marine Corps); Fire Scout 
(Navy and Army). Currently efforts are underway to further increase 
cooperation between the Air Force and Army in the Predator and Warrior 
Programs. Air Force recently utilized Army tooling to produce the first 
two Air Force Block X airframes (Warrior common) and previously, the 
Air Force permitted the Army to use tooling to produce the Army 
extended range I-GNATS and Warrior-As (both MQ-1 Predator airframes). 
Additionally, the Air Force loaned significant spares and sensors to 
the Army to support combat operations. 

The report does not offer sufficient evidence that a single point of 
authority, beyond those currently belonging to the DEPSECDEF and 
SECDEF, is required for resource decisions. 

* The report concluded that these programs should consider developing a 
business case and critical system knowledge (pg 7); and the report 
acknowledges the Department currently has a directive addressing this 
approach (pg 8; DoD Instruction 5000.2, Operation of Defense 
Acquisition System, May 2002). 

* Oversight of these processes currently falls under the Department's 
single acquisition authority. 

The report did not comment on the efforts currently underway within the 
Department on consolidating ISR development efforts found in the UAV 
Roadmap and other ISR roadmaps. The Department is utilizing an 
enterprise-level strategy for Unmanned Systems technology which 
supports several mission areas including the ISR mission area. This 
roadmap identifies war-fighter needs for multiple mission areas 
including missions falling in the ISR domain. The roadmap also 
identifies technology trends and developments for areas such as 
processors, communications, platforms, and payloads. Finally, 
integrated capability and mission roadmaps are provided to identify 
technology and schedule options for meeting the various war-fighter 
mission needs. This technology roadmap is being expanded in 2007 to 
incorporate all Unmanned Systems in a single roadmap, to better support 
integrated war- fighter needs independent of individual Military 
Service or system capability. The current and future roadmap, UAS and 
Unmanned Systems Roadmap, also support the USD(I) ISR mission roadmap 
as many individual Military Service ISR systems transition to Unmanned 
Systems. 

The report does not recognize ground component requirements and CONOPS 
for multiple joint missions. This is made clear on page 14 of the 
report: "Although limited progress has been made, the services continue 
to have different concepts of operation and requirements more than a 
year after discussions began." 

The report did not recognize the benefits of acquisition programs with 
unique requirements and the benefit of competition. 

Recommendation 2: Report to the defense committees by August 1, 2007, 
the results of the ISR studies and identify the specific plans and 
actions needed and intended to make joint acquisition decisions in ISR 
programs and improve the way it plans, buys, organizes, manages, and 
executives its ISR acquisition programs and operations. 

Response To Recommendation 2: Concur. The Department can report interim 
status to the committees on the progress of the ISR Portfolio 
Management Pilot program by August l, 2007.-There are two pertinent 
efforts, "Optimization of ISR Capabilities" sponsored by the Air Force 
and the Defense Science Board's "Task Force on Integrating Sensor- 
Collected Intelligence" that are not scheduled to complete work in time 
to provide input to the defense committees. The Department recommends 
moving the suspense date to December 31, 2007 to ensure adequate 
analysis and integration of study findings.

FOOTNOTES 

[1] The additional funding does not include DOD or service requests for 
supplemental funding in fiscal year 2007 or 2008. 

[2] All of these 13 programs are in technology development, or systems 
development and demonstration as defined by DOD Instruction 5000.2, 
Operation of the Defense Acquisition System (May 12, 2003). The purpose 
of development is to reduce technology risk and to determine the 
appropriate set of technologies to be integrated into a full system. 

[3] DOD Instruction 5000.2, Operation of the Defense Acquisition System 
(May 12, 2003). 

[4] 10 USC 2433 requires the Secretary concerned to report to Congress 
when a program's unit cost increases by at least 15 percent over the 
current baseline estimate or increases by 30 percent over the original 
baseline estimate and requires the Secretary of Defense to carry out an 
assessment of the program and provide written certification to Congress 
when a program's unit cost increases by at least 25 percent over the 
current estimate or increases by 50 percent over the original baseline 
estimate. 

[5] The Navy's fiscal year 2004 budget did not include any funding for 
ACS because it was submitted before the decision to jointly acquire ACS 
with the Army. 

[6] The Army's Future Combat Systems (FCS), a family of systems that 
will equip the Army's transformational combat brigades, are composed of 
unmanned ground and air vehicles (including the Fire Scout), networked 
combat and sustainment systems, and unattended sensors and munitions. 
FCS is about half-way through its development. 

[7] The Navy acquired two older (RQ-4A) Global Hawk aircraft for the 
demonstration. These aircraft were configured with radar software that 
incorporates maritime search and inverse SAR modes. 

[8] The Air Force requires pilots who are formally trained and rated 
according to Air Force aeronautical standards. These standards include 
several levels of pilot training, experience, and military flying time. 
In contrast, the Army uses highly trained enlisted operators. Since 
most of its unmanned systems have automatic takeoff and landing 
capability, the Army does not require rated pilots to operate them. 

[9] These quantities do not include those to be acquired as a result of 
additional funding provided by Congress in earlier years or quantities 
associated with supplemental requests. 

[10] Bandwidth refers to the available frequencies to support the 
flight of a UAS and is needed to support systems that control the 
flight of certain unmanned aircraft, to transmit data collected by 
payload sensors, and to interface with air traffic control centers. 
Because UAS and other weapons or communications systems, including 
manned aircraft, often operate on the same frequency, certain 
frequencies can become congested and interference can occur.

[14] The Joint Staff identifies 31 core ISR systems; our review 
included 14 of them. We added two programs that are developing payloads 
for ISR systems and three more systems that were in development but 
were not part of the core group as of August 2006 when we established 
our list. 

[15] Milestone B is the initiation of an acquisition program as defined 
by DOD Instruction 5000.2, Operation of the Defense Acquisition System 
(May 12, 2003). 

[16] Several other studies were commissioned but information related to 
them is classified and cannot be summarized here. 

[17] The Defense Science Board is composed of members designated from 
civilian life by the Under Secretary of Defense (Acquisition, 
Technology and Logistics) and advises the Secretary of Defense; the 
Deputy Secretary of Defense; the Under Secretary of Defense for 
Acquisition, Technology and Logistics; and the Chairman of the Joint 
Chiefs of Staff on scientific, technical, manufacturing, acquisition 
process, and other matters of special interest to the DOD.
