GAO Highlights: 

Highlights of GAO-08-877, a report to the Subcommittee on Air and Land 
Forces, Committee on Armed Services, House of Representatives. 

Why GAO Did This Study: 

The Department of Defense (DOD) has spent an estimated $12 billion on 
the development and production of tactical radios over the last 5 
years—about as much as was spent producing Virginia Class submarines 
($10.8 billion) in the same period. Survivability and lethality in 
warfare are increasingly dependent on superior information and 
communication capabilities. DOD is counting on the Joint Tactical Radio 
System (JTRS) to deliver the breakthroughs in this area. At the same 
time as it is developing JTRS, DOD wants to ensure that current forces 
are equipped with sufficient legacy radios. To address Subcommittee 
concerns regarding DOD's approach to meeting current and future radio 
needs, GAO examined this subject. In response, this report addresses 
(1) how planned investments in key tactical radio systems changed over 
the last 5 years, (2) why these changes occurred, and (3) the 
challenges ahead. 

To assess these topics, GAO’s work included reviewing 2003 through 2007 
budget requests, legacy radio procurements, and the status of the JTRS 
program; and interviewing officials from DOD organizations. 

What GAO Found: 

Over the past 5 years, DOD investments in key tactical radios have 
shifted dramatically, both in size and composition. In 2002, when JTRS 
first began system development, DOD planned to invest close to $3 
billion in JTRS over fiscal years 2003-2007. However, as shown below, 
actual investments more than doubled and shifted to producing thousands 
more legacy radios. Compared with the $3.2 billion that was slated to 
be spent on JTRS and the Army and Marine Corps legacy radios, about 
$8.3 billion was actually spent. Of this, about $5.7 billion was spent 
on the legacy radios, while $2.5 billion was spent on JTRS development.

[End of figure] 

The change in tactical radio investments was brought about by (1) 
delays in the development and production of JTRS and (2) urgent demands 
for more radios to equip current forces. JTRS has encountered 
significant cost, schedule, and performance problems, causing some 
users to buy more legacy radios instead. Moreover, the military 
services’ demand for tactical radios soared because of combat 
operations, the need to equip Guard and Reserve forces with modern 
radios, and to add more radios per combat unit. Supplemental funding of 
$5.5 billion paid for most of these legacy radios. 

Over the next 5 years, DOD faces several challenges in providing needed 
tactical communications capabilities to the warfighter, including: 

* Overcoming technology hurdles, size and power constraints, and 
security architecture issues to complete JTRS development. 

* Managing investments within defined fiscal constraints. A legacy 
vehicle radio costs about $20,000, while its more capable JTRS 
replacement is estimated to cost up to 10 times more. 

* Phasing in JTRS without prematurely retiring a relatively young 
inventory of legacy radios. 

DOD does not have a strategy to meet these challenges and thus runs the 
risk of having its future communications capabilities decided ad hoc. 

What GAO Recommends: 

GAO recommends that the Secretary of Defense develop a comprehensive 
investment strategy for tactical radios and take actions to improve 
oversight of their acquisition. In commenting on a draft of this report 
DOD agreed with these recommendations.

The Honorable Jim Saxton:
Ranking Member:
Subcommittee on Air and Land Forces:
Committee on Armed Services:
House of Representatives: 

The Department of Defense (DOD) has spent an estimated $12 billion on 
the development and production of tactical radios over the last 5 
years. To put this investment in context, the amount spent on tactical 
radios is comparable to the estimated investments made in the Army's 
Future Combat Systems ($10.4 billion) and the Navy's production of 
Virginia Class submarines ($10.8 billion) during the same period. 

Survivability and lethality in warfare are increasingly dependent on 
smaller, highly mobile, joint forces that rely on superior information 
and communication capabilities. Moving this information--including 
bandwidth-intensive data and video--to, from, and across the 
battlefield requires breakthroughs in radio technology. DOD's existing 
or "legacy" radios lack the capacity and flexibility necessary to 
achieve and maintain this level of information superiority. DOD is 
counting on the Joint Tactical Radio System (JTRS), a development 
program begun in 1997, to deliver the needed breakthrough. JTRS relies 
on networked communications to improve information sharing, 
collaboration, and situational awareness, thus enabling more rapid and 
effective decision making and execution on the battlefield. It is 
intended to provide the bandwidth volume to handle the information 
traffic, emulate different legacy radios, and function as a router for 
tactical networks. The design of some new weapon systems, such as the 
Future Combat Systems, depends on a JTRS-equipped network. 

At the same time DOD is developing JTRS for future forces, it is 
striving to ensure that current forces are equipped with legacy radios 
to carry out assigned missions. DOD is confronted with the challenge of 
balancing the investment in both current and future radios--a dynamic 
proposition given that current needs change and future capabilities do 
not necessarily proceed predictably. To determine whether DOD and the 
military services are acquiring radios in the most cost-efficient and 
effective manner and have developed a strategy to balance near-and long-
term requirements, address capability gaps, and determine funding 
needs, the Subcommittee requested that GAO study how effectively DOD 
and the military services are managing the acquisition of radio 
systems. Specifically we (1) examined how the services' planned 
investments in key tactical radio systems have changed over the last 5 
years, (2) determined why these changes occurred, and (3) identified 
challenges that will confront the services as they plan tactical radio 
investments to provide desired future capabilities. 

We conducted this performance audit from July 2007 to July 2008 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. 

To assess tactical radio investments and risks, we reviewed fiscal year 
2003 through 2007 budget[Footnote 1] requests, procurements of legacy 
radios for that time period, the current status of the JTRS program, 
and JTRS migration plans. We interviewed agency officials from various 
DOD and service organizations and reviewed plans and reports produced 
by Defense organizations. More details about our scope and methodology 
are in appendix I. 

Results in Brief: 

Over the past 5 years, DOD investments in key tactical radios have 
shifted dramatically, both in size and composition. In 2002, when the 
JTRS program began system development, DOD planned to invest close to 
$3 billion in JTRS over fiscal years 2003-2007--about $1 billion to 
develop and test the radios and another $2 billion to start procuring 
them. Investment in legacy radios was expected to be relatively small 
and diminish almost entirely as JTRS became available. For example, the 
Army and Marine Corps planned to spend only about $235 million between 
2003 and 2007 on legacy radios for ground vehicles and soldiers/ 
marines. However, actual investments more than doubled and shifted away 
from planning to produce JTRS to producing thousands more legacy 
radios. Compared with the $3.2 billion that was slated to be spent on 
JTRS and the Army and Marine Corps legacy radios, about $8.3 billion 
was actually spent. Of this, about $5.7 billion was spent on the legacy 
radios, while $2.5 billion was spent on JTRS development. Other than 
fielding an enhanced legacy handheld radio, no JTRS networking radios 
were produced or fielded during this time. 

The change in tactical radio investments was brought about by two 
primary factors: (1) delays in the development and production of JTRS 
and (2) urgent demands for additional radios to equip current forces. 
JTRS encountered significant cost, schedule, and performance problems 
early in its development. The program was restructured in 2006, 
resulting in the deferral of some capabilities and the addition of much 
more time and funding to complete development. While prudent, the 
restructuring delayed the fielding of the first JTRS Ground Mobile 
Radios by 5 years to 2010. Because of the delay, some users who were 
depending on JTRS such as Army helicopter programs had to buy more 
legacy radios instead. At the same time, however, the military 
services' demand for tactical radios soared--a demand that was met by 
buying tens of thousands of legacy radios. The demand was fueled by 
combat operations in Iraq and Afghanistan, the need to equip Guard and 
Reserve forces with modern radios, and a change in the Army and Marine 
Corps' concept of operations that calls for more radios per combat 
unit. The resultant investments in legacy radios have evolved from year 
to year, as the services reacted to needs that cropped up, and were 
largely enabled by supplemental funding, which supplied most--an 
estimated $5.5 billion--of the additional funds. Because DOD developed 
the supplemental budgets relatively quickly and without the level of 
review and oversight normally required through the regular annual 
budget process, there was limited visibility into the services' plans 
for acquiring tactical radios. In addition, a waiver/notification 
process established by the Office of the Secretary of Defense to help 
manage the transition from legacy radios to JTRS has not been effective 
in tracking the nature and extent of tactical radio investments. 

Over the next 5 years, DOD faces several challenges in providing needed 
tactical communications capabilities to the warfighter: completing JTRS 
development, managing investments within tighter fiscal constraints, 
and developing a fielding strategy for tactical radios. While JTRS is 
making progress, the program must still overcome technology hurdles, 
size and power constraints, and security architecture issues to avoid 
further delays. The high cost of JTRS has also become an increasing 
concern. Currently, a legacy vehicle radio costs about $20,000, while 
its JTRS replacement, albeit significantly more capable, is estimated 
to cost up to 10 times more. In addition, the cost of integrating JTRS 
with existing weapons systems is expected to be substantial in some 
cases. Thus, the decision to put more radios in each combat unit may 
not be sustainable with the more costly JTRS. In fact, the military 
services have begun to scale back the number of JTRS radios they plan 
to buy and rethink how JTRS capabilities will be fielded. Since the 
recently purchased legacy radios are expected to have a useful life of 
10-15 years, fielding JTRS without phasing out legacy radios 
prematurely will necessitate striking a balance between capability and 
cost. For example, DOD may have to consider whether the investment 
priority for JTRS should be on network-dependent systems, like the 
Army's Future Combat Systems, or for replacing legacy radios. Available 
funding, absent continued high levels of supplemental budgets, will 
likely not support meeting both sets of needs. However, DOD does not 
have a strategy for balancing its future tactical radio investments, as 
previous plans are outdated. 

We are recommending that the Secretary of Defense develop an investment 
strategy that establishes priorities to guide resource decisions on 
legacy radios, upgraded radios, and the new generation of radios that 
JTRS represents. We are also recommending that such a strategy provide 
discipline to bound investment decisions, such as a reinvigorated 
notification/waiver process, as well as a back-up plan in the event 
that JTRS does not provide the desired capabilities on time. In 
commenting on a draft of this report, DOD agreed with these 
recommendations. 

Background: 

Survivability and lethality in warfare are increasingly dependent on 
smaller, highly mobile, joint forces that rely on superior information 
and communication capabilities. DOD's existing tactical radio systems 
lack the functionality and flexibility necessary to achieve and 
maintain information superiority or to support the rapid mobility and 
interoperability desired by armed forces. Most of these radios were 
designed with mutually exclusive architectures to perform specific 
tasks and can only interoperate with like radios. Their functions are 
largely governed by their hardware components. In addition, they 
operate at low to medium data rates, have limited networking 
capabilities, and are not capable of simultaneous voice, data, and 
video operations. Furthermore, the radios have many unique components 
and parts that require specialized support and create a logistics 
burden. 

The military services use many different types of tactical radios, 
including some that were developed decades ago. The Single Channel 
Ground and Airborne Radio System (SINCGARS) is the primary means of 
command and control for Army combat and support units. Different 
variants of the radio are used in vehicles, aircraft, and as "manpack" 
radios carried by soldiers. The radios provide voice and limited data 
capabilities. The Marine Corps also uses SINCGARS, but also relies on 
the AN/VRC-110 and the AN/VRC-111 radios for its vehicles. These radios 
have multiple waveforms,[Footnote 2] including the SINCGARS waveform, 
and can be pulled out of vehicles and used as handheld radios. The Navy 
and Air Force use a variety of radios for their airborne platforms; one 
of the most common is the AN/ARC-210, a single-channel radio which 
provides voice and data communications over a variety of waveforms. To 
meet its fixed station and maritime needs, the Navy uses the Digital 
Modular Radio, which operates on multiple waveforms and provides voice 
and data capabilities, and other radios. Appendix II provides a more 
complete list of selected tactical radios currently in use and their 
capabilities. 

To support new operational and mission requirements, DOD determined 
that the large number and diversity of legacy radios in use would 
require wholesale replacement or expensive modifications. The JTRS 
program was initiated in 1997 to exploit advancements in software- 
defined radio technology and provide superior communications and 
networking capabilities to the warfighter. Software-defined radios such 
as JTRS use software rather than hardware to control how the radio 
works and, as a result, offer significant flexibility to meet a wide 
variety of needs. Rather than developing radios that are built to 
different standards and operate on different frequencies as was the 
case in the past, DOD will develop JTRS as a single, interoperable 
family of radios based on a common set of standards and applications. 
The radios are expected to not only satisfy the requirements common to 
the military's three operational domains--air, sea, and ground--but be 
able to communicate directly with many of DOD's existing tactical 
radios. 

In addition to supporting interoperability, JTRS is intended to 
contribute to DOD's goal of network-centric warfare operations by 
introducing new wideband networking waveforms that dramatically 
increase the amount of data and speed at which the data can be 
transmitted. The wideband networking waveform being developed for 
ground vehicles, for example, is expected to provide data rates of up 
to 5 megabits per second or more which is at least ten times faster 
than legacy radio systems--akin to upgrading from a "dial-up" modem to 
a broadband connection. As such, the waveforms would facilitate the use 
of maps, imagery, and video to support the decision making of tactical 
commanders at all echelons. Table 1 compares the frequency band, 
nominal channel bandwidth, and data rates of selected legacy waveforms 
and new wideband waveforms.

[A] The Wideband Networking Waveform and Soldier Radio Waveform are 
actually families of waveforms. The Wideband Networking Waveform family 
consists of four different waveforms and the Soldier Radio Waveform 
family consists of three different waveforms. 

[End of table] 

In addition to providing new wideband waveforms, individual JTRS radios 
would have the capability to support multiple services (e.g., voice, 
data, and video) and operate on multiple channels simultaneously. For 
example, a four-channel JTRS radio set intended for a ground vehicle 
could be programmed to have channels dedicated to SINCGARS, EPLRS, the 
Wideband Networking Waveform, and the Soldier Radio Waveform. All four 
channels could be operating simultaneously. Data could also be 
transferred from one channel (or network) to another through a 
"gateway" device implemented with hardware and software. Furthermore, 
since JTRS is expected to operate as a mobile network, each multi- 
channel JTRS set will function as a router, meaning that it is 
responsible for passing along information (voice, data, and video) from 
other JTRS radios. 

To manage JTRS' development, DOD established a joint program office, 
and service-led product offices clustered by requirements. In 2006, all 
the JTRS programs were realigned under the authority of a single JTRS 
Joint Program Executive Officer (JPEO). The JPEO established an 
organizational structure for JTRS that includes three domains: (1) 
ground radios; (2) air, maritime, and fixed station; and (3) network 
enterprise services and a program for special radios. 

In an effort to manage the transition of tactical radios to JTRS, in 
1998, the Office of the Assistant Secretary of Defense for Command, 
Control, Communications, and Intelligence issued a memorandum directing 
all Component efforts to develop and acquire any radio system be held 
in abeyance. Service, command, or agency acquisition executives could 
submit requests for exceptions through the JTRS Joint Program Office 
and the Assistant Secretary of Defense for Networks and Information 
Integration.[Footnote 3] The request for exceptions (or waiver policy) 
was amended in May 2005. The amended policy suspended the waiver 
process and only required that notifications of plans to acquire radios 
be provided to the Assistant Secretary of Defense for Networks and 
Information Integration. 

Investment in Key Tactical Radio Systems Has Shifted Dramatically in 
Both Size and Composition: 

Over the past 5 years, investments in key tactical radios systems have 
exceeded planned investments by more than double and shifted 
dramatically in scope. In 2003, DOD and the services planned to invest 
mainly in the development and production of JTRS. At the same time, 
investment in legacy radios was expected to be relatively small and 
diminish almost entirely as JTRS became available. However, actual 
spending on tactical radios turned out to be very different. Not only 
did spending between fiscal years 2003 and 2007 increase significantly, 
from about $3.2 billion to about $8.3 billion, it shifted away from 
procuring JTRS to procuring tens of thousands of additional legacy 
radios. See figure 1. 

Figure 1: Comparison of Planned and Actual Spending for Tactical 
Radios:

Development and Procurement of Tactical Radios, fiscal years 2003 and 
2007:

JTRS: $2.54 billion.

[End of figure] 

In 2003, DOD and the services planned to spend approximately $3 billion 
on JTRS over the next 5 years--$1 billion for research and development, 
and $2 billion to procure the first JTRS radios. The Army and Marine 
Corps planned to spend approximately $235 million for legacy radios 
between 2003 and 2007. The Army planned to spend approximately $140 
million to procure SINCGARS and handheld and "manpack" radios; the 
Marine Corps planned to spend about $98 million to procure a variety of 
tactical communications systems. 

In actuality, DOD and the services invested over twice as much as 
planned to develop JTRS capabilities--about $2.5 billion--while no JTRS 
networking radios were produced during this time. Legacy radio 
spending, on the other hand, ballooned to approximately $5.7 billion, 
about 24 times what was planned. Of this, the Army spent approximately 
$4.1 billion, including $2.3 billion on SINCGARS radios and $1.8 
billion on handheld and manpack radios. The Marine Corps spent $1.6 
billion on a variety of tactical communication systems. 

Dramatic Change in Tactical Radio Investments Is Due Primarily to 
Delays with JTRS and Near-Term Operational Needs: 

The dramatic change in the size and scope of tactical radio investments 
over the last 5 years is due to two primary factors. First, cost, 
schedule, and performance problems delayed development of JTRS 
capabilities by several years. Second, combat operations in Afghanistan 
and Iraq have significantly increased the demand for tactical radios-- 
a demand that could only be met by buying legacy radios. The demand was 
driven by a desire to equip deploying units with modern radios and a 
change in concept of operations that calls for more radios per unit. 
The resultant investment in legacy radios evolved from year to year as 
needs arose and was largely enabled by the availability of supplemental 
funding. Although a notification process was established to help manage 
the transition from legacy radios to JTRS, it was not effective in 
tracking the extent of investments in legacy radios that occurred. 

Development and Production of JTRS Delayed by Several Years: 

As we have previously reported, developing JTRS has proven to be a 
significant technical and management challenge.[Footnote 4] A few years 
into system development, the program experienced considerable cost and 
schedule overruns and performance shortfalls, necessitating a major 
restructuring of the program in 2006. As a result, considerably more 
time and funding were added to complete the first increment of JTRS. 
The revised schedules for each of the JTRS program components expanded 
development times by several years (see Fig. 2). 

Figure 2: Impact of Restructuring on JTRS Schedules: 

[See PDF for image] 

This figure is an illustration of the impact of restructuring on JTRS 
schedules, as follows: 

Ground Mobile radios: Low-rate production decision; 
Original: 2005; 
New: 2010. 

Handheld, Manpack, and Small Form Fit: Low-rate production decision; 
Original: 2008; 
New: 2010. 

Airborne, Maritime, and Fixed Station radios: System development and 
demonstration decision; 
Original: 2006; 
New: 2008. 

Source: GAO analysis of JTRS JPEO data. 

[A] The pre-and post restructuring components of the Handheld, Manpack, 
and Small Form Fit program did not lend themselves to a direct 
comparison. For figure 2, we compared the two components that were the 
closest in scope. The pre restructuring component was Spiral 2, which 
consisted of 1-and 2-channel Handhelds, an enhanced 2-channel Manpack, 
and Small Form Fit variants A through L. The post restructuring 
component was Phase 2, which consists of a 2-channel Handheld, 2- 
channel Manpack, and Small Form Fit variants B, C, D, I, and J. 

[End of figure] 

The production decision for the Ground Mobile Radio variants, for 
example, was delayed by 5 years, from 2005 to 2010. In addition, the 
start of system development for the Airborne, Maritime, and Fixed 
Station radios was delayed by 2 years. Although the Airborne, Maritime, 
and Fixed Station program went through a presystem development phase to 
reduce technical risks associated with developing airborne networking 
capabilities, the program was delayed from starting until costs and 
production quantities could be worked out. Overall, the estimated cost 
to develop JTRS and its various program components increased from about 
$3.5 billion to almost $6 billion through fiscal year 2011. 

Problems encountered with JTRS were largely the result of starting 
system development with immature technologies, unstable requirements, 
and aggressive schedules. The Army-led JTRS program for ground vehicles 
and helicopters,[Footnote 5] for example, began system development in 
2002 with none of its 20 critical technologies sufficiently matured, 
requirements not clearly defined, and a compressed development schedule 
that allowed too little time for testing. As a result, the program 
struggled to mature and integrate technologies to meet size, weight, 
and power constraints and evolving security requirements for the 
radios, and was forced to make design changes to address these issues. 
Meeting requirements in the JTRS Handheld, Manpack, and Small Form Fit 
radio program also proved to be challenging, given the smaller size, 
weight, and power needs for these radios. 

DOD restructured the JTRS program to reduce risk and establish a more 
incremental approach to developing JTRS capabilities. In restructuring 
JTRS, DOD deferred several requirements and radio features to later 
program increments. For example, DOD reduced the number of radio 
variants by half (26 to 13) and the number of waveforms by about two- 
thirds (32 to 11). The original intent of JTRS was to allow most 
waveforms to operate on most of the radio variants. By reducing the 
number of waveforms per radio variant, DOD expected to reduce costly 
porting efforts--software development needed to make a waveform work on 
different radio variants--and more readily address size, weight, and 
power constraints. 

Although JTRS will deliver radios significantly later than initially 
planned, the program is still intended to meet the needs of key users 
such as the Future Combat Systems (FCS) program. FCS, which is a large 
and complex effort by the Army to develop a suite of new weapon systems 
and vehicles linked by a new information network, is depending on 
several JTRS variants and wideband waveforms to provide critical 
communications and networking capabilities. However, as we have 
reported over the past several years, the FCS program has struggled to 
define requirements and mature critical technologies, and is at risk of 
incurring further cost and schedule delays.[Footnote 6] 

Several other users depending on JTRS have had to invest in legacy 
radio systems to meet their needs because of the delays with the 
program. For example: 

* Army Aviation, which needed JTRS to provide the required 
interoperability capability for Future Force and Joint Force 
operations, was planning to buy JTRS radios for its helicopters 
starting in fiscal year 2006. Several Army helicopter systems, such as 
the Longbow Apache (AH-64D), are being modernized and the Army planned 
to integrate JTRS sets into these aircraft. According to the Army, the 
aircraft modernization work could not be delayed until JTRS becomes 
available and the aircraft would not be mission capable without a 
communications package. As a result, the Army decided to buy an 
alternative legacy radio system to fulfill this need. According to Army 
estimates, it will spend approximately $310 million between 2005 and 
2013 to procure the alternate radio system for various helicopter 
programs. 

* The Air Force and Navy also had to procure legacy communications 
systems for various aircraft systems and ships that were either in 
production or being upgraded. The Air Force, for example, requested AN/ 
ARC-210 radios for the Global Hawk, F-15E, F-16 Block 40/42, and A-10 
aircraft while the Navy requested Digital Modular Radios for new ship 
construction in support of the National Defense Sealift Fund. 

* The Navy is modernizing the AN/ARC-210 radio in part because of the 
need to add certain capabilities that will not be filled by the first 
increment of JTRS. For example, it is adding the capability to host a 
Joint Precision Approach and Landing System waveform to the AN/ARC-210. 
The new approach and landing system, which is intended to provide more 
accurate Global Positioning System (GPS)-based landing guidance for 
aircraft during all weather conditions, has been in development in DOD 
for several years. The Navy is also modernizing the AN/ARC-210 to 
address National Security Agency (NSA) requirements for cryptographic 
obsolescence in legacy radio systems.[Footnote 7] According to Navy 
officials, the Navy plans to spend approximately $50 million in 
research and development for the modernization of the AN/ARC-210 radio. 

Combat Operations and Force Modernization Requirements Have Increased 
the Demand for Tactical Legacy Radios: 

Combat operations in Afghanistan and Iraq have also been a key reason 
for the huge increase in spending on legacy radios by the Army and 
Marine Corps. With the build-up of the war, tactical radios have become 
critical to conducting operations. According to the Army and Marine 
Corps, legacy radios were purchased to ensure units being deployed had 
modern communications capabilities. In some cases, newer versions of 
legacy radios were purchased to replace older radios and to ensure 
units were equipped to wartime readiness levels. This included, for 
example, replacing several thousand Vietnam-era radios that still 
existed in certain Army National Guard and Reserve units with SINCGARS 
radios. In addition, as we have previously reported,[Footnote 8] some 
Army National Guard units were equipped at less than wartime readiness 
levels (often at 65 to 75 percent of requirements) under the assumption 
that there would be sufficient time for Guard forces to obtain 
additional equipment prior to deployment. While the Army was able to 
transfer equipment from non-deploying units to deploying units to 
compensate for some of these shortages in the near term, the large 
number of units needed for deployment required the purchase of 
additional communications equipment. 

According to Marine Corps officials, before combat operations in Iraq 
and Afghanistan started, the Marine Corps had envisioned keeping many 
of its aging legacy radios until the introduction of JTRS radios could 
replace them. However, as operations got under way, the Marine Corps 
began modernizing its inventory of radios, replacing them with newer 
legacy radios that provided improved on-the-move and over-the-horizon 
communications capabilities. The Marine Corps, for example, replaced 
older versions of SINCGARS and other manpack radios with newer multi- 
band radios that allow a marine to operate a single radio in either 
VHF, UHF line-of-site, or UHF SATCOM modes of operation. In addition, 
the Army and Marine Corps needed radios to replace combat losses and to 
equip new force protection vehicles being procured, such as up-armored 
High Mobility Multipurpose Wheeled vehicles and, more recently, the 
Mine Resistant Ambush Protected vehicles. 

The Army and Marine Corps have also increased the number of radios to 
combat and support units based on lessons learned from combat 
operations. As a result of attacks against combat and support vehicles 
that did not have sufficient communications capabilities, the services 
have been pursuing a strategy to equip virtually every vehicle being 
used in combat operations with a radio. For example, very few trucks in 
logistics units were supplied with tactical radios; however, the threat 
to supply convoys made providing these units with radios more critical. 
Furthermore, the services have expanded communications to platoon and 
squad levels of the force, purchasing handheld and intra-squad radios 
for soldiers who previously had no radios. For example, a typical 
Marine Corps rifle company, which consists of about 180 marines, was 
equipped with 9 tactical radios prior to the war in Iraq. The same 
rifle company is now equipped with about 225 radios, most of which are 
intended for intra-squad communications. 

Moreover, since 2004, the Army has also been going through a major 
force restructuring--referred to as modularity--that has driven 
requirements to field more tactical radios to lower echelon units. In 
restructuring the force, the Army has established modular Brigade 
Combat Teams and Support Brigades that are designed, equipped, and 
staffed differently than the units they replace. The new brigades are 
intended to be more self-sustainable, agile, and deployable through the 
introduction of key enablers such as enhanced military intelligence and 
communications capabilities. In September 2004, the Army estimated it 
would need an additional 66,166 SINCGARS receiver/transmitter units to 
support the modularity initiative. Without additional tactical radios, 
the Army could not achieve its intended design objectives for these 
brigade units. 

According to Army officials, increased demands for equipment, like 
radios, are translated into specific quantities the Army refers to as 
authorized acquisition objectives. The acquisition objective 
establishes the total quantity of a piece of equipment needed to supply 
and sustain the force and is not intended to be constrained in terms of 
available resources. In the Army, acquisition objectives are derived 
from force structure reviews that analyze threat, operational 
conditions, and force readiness. As shown in figure 3, since 2002, the 
Army's acquisition objective for SINCGARS ground radios increased 
steadily, from about 232,000 radio receiver/transmitter units[Footnote 
9] in fiscal year 2002 to more than 526,000 units in 2007, reflecting 
the emergence of new requirements for radios. The Army bought 244,780 
SINCGARS between 2003 and 2007 to meet this objective.

Investment in Tactical Radios Evolved From Year to Year as Supplemental 
Funding Became Available: 

The increased demand for legacy radios was largely facilitated through 
the availability of supplemental funding, which provided the vast 
majority of funding to procure these radios. Between 2003 and 2007, 
supplemental funding supplied an estimated 90 percent--$5.5 out of $6.1 
billion--of the funding the Army and Marine Corps received to procure 
legacy radios (see figure 4). DOD and the services requested a 
relatively small proportion of funding through the regular budget 
process.

[End of figure] 

The reliance on supplemental budgets to acquire tactical radios 
continued in fiscal year 2008, with the Army and Marine Corps 
requesting an additional $3.3 billion in October 2007. Although 
Congress did not act on the budget request, DOD resubmitted the request 
in February 2008. In March 2008, however, the Army informed Congress 
that it had overstated its request for SINCGARS funding by $1.7 
billion; the Army had requested funds for 170,756 more SINCGARS, when 
only 56,000 were needed to meet its authorized acquisition objective. 

Because DOD's regular budget process is lengthy--it takes 18 months to 
plan, develop, and complete an annual budget submission to Congress-- 
the services should identify potential offsets when seeking additional 
funding in excess of budget-year guidance levels. Supplemental budgets 
provided an opportunity for the services to respond to emerging needs 
relatively quickly and to request funding without having to trade 
against other ongoing or planned weapon system investments. However, 
because supplemental budgets were developed quickly and as one-time 
requests to address immediate needs, they offered little visibility 
into the services plans for acquiring tactical radios. 

The huge increase in legacy radio investments was also facilitated by 
the suspension of a JTRS waiver process. In 1998, DOD instituted a 
waiver policy in order to control the acquisition of legacy radios in 
anticipation of JTRS capabilities becoming available. In May 2005, in 
response to delays with the delivery of JTRS products, DOD suspended 
the waiver policy for tactical radios. However, in order to maintain 
visibility into legacy procurement activities, DOD still required the 
services to notify the Office of the Assistant Secretary of Defense for 
Networks and Information Integration (Office) prior to any procurement 
actions to buy tactical radios. In notifying the Office of procurement 
actions, the services were required to identify the requirements 
necessitating the procurement and whether any operational impacts would 
result if the request was disapproved. According to data the Office has 
collected through federal contract announcements and other means, 
notifications from the services have been inconsistent and do not 
reflect all tactical radio procurements that took place over the past 
several years. In addition, according to a representative of the 
Office, notifications that were submitted by the services did not 
provide sufficient detail to understand why radios were being procured 
or how the procurement actions fit in with other procurements. 

Strategy for Acquiring Tactical Radios over Next Several Years in Flux: 

DOD's original strategy for acquiring tactical radios centered on JTRS 
as a replacement for legacy radios and a means to achieve new 
networking capabilities. While JTRS has made progress in developing 
radio products and waveforms, it must still resolve key technical 
hurdles that could lead to further delays in the program. When JTRS 
actually becomes available, however, the strategy of replacing legacy 
radios as previously envisioned may no longer be an option in view of 
(1) the potentially smaller market for JTRS given the large, 
unanticipated purchase of legacy radios that have many years of life 
left and (2) the need to manage investments within reasonable funding 
expectations. In addition, while JTRS radios may offer significant new 
capabilities, they are much costlier than legacy radios and in some 
cases additional large investments are required to fully integrate them 
into existing military platforms. These costs may run counter to recent 
decisions to significantly increase the numbers of radios issued to 
each unit. The high costs of JTRS radios have led to the services to 
scale back their plans for acquiring the radios and have also led to 
recent efforts to seek lower cost alternatives. Fielding JTRS 
expeditiously while making the most out of the large investment in 
legacy radios will necessitate striking a balance--both in terms of 
capability and cost. DOD, however, does not yet have a strategy for 
guiding the services' acquisition of tactical radios over the next 
several years. 

JTRS Program Must Still Resolve Technology Issues: 

The JTRS program has made progress since being restructured. Early 
prototypes of JTRS ground radio variants and networking waveforms have 
been developed and some JTRS capabilities have been demonstrated in a 
laboratory environment and, to a lesser extent, during recent field 
experiments. However, significant technological challenges remain that 
place completion of JTRS development at risk. In particular, designing 
JTRS radios that meet operational requirements within required size, 
weight, and power constraints has proven to be particularly challenging 
for several of the JTRS radio configurations. Moreover, the transition 
from legacy radios that operate at a single level of security and have 
their functionality defined in hardware to networked radios that 
operate at multiple levels of security and have their functionality 
defined in software has raised new concerns about tactical radios' 
security architecture--concerns that were not fully appreciated when 
the JTRS program began. Whether or not these technical challenges can 
be overcome will not be known until major test and evaluation events 
are conducted in the next few years. 

JTRS radios require significant amounts of memory and processing power, 
particularly to run the new transformational networking waveforms that 
will enable network-centric operations. The processing power required 
to run these networking waveforms rapidly consumes electric power in 
the radios and generates a significant amount of heat, which must be 
dissipated to keep the electronic components of the radio operating at 
a safe temperature. Dissipating heat often requires increasing the size 
and weight of the radio. However, keeping size, weight, and power 
consumption to an absolute minimum is a critical operational 
requirement for JTRS and particularly for the Handheld, Manpack, and 
Small Form Fit variants. For example, the JTRS program is attempting to 
develop a 2-channel handheld radio weighing no more than 3.8 pounds 
that is capable of running the Soldier Radio Waveform, as well as key 
legacy waveforms. The challenge of meeting these design constraints has 
prompted the program manager to identify size, weight, and thermal 
management as high-risk elements for the JTRS 2-channel handheld radio 
development. Although the recently started Airborne, Maritime, and 
Fixed-Station program should benefit from the system development 
experiences of the earlier JTRS programs, its size, weight, power, and 
thermal issues are currently seen as a key program risk. 

JTRS radios must address stringent security architecture requirements 
established by the NSA and must be certified through a multistage 
process during their design and development. Certification is a 
rigorous and potentially time-consuming process, and consequently must 
be factored into the schedule for each radio's system development. 
While JTRS developers must be concerned with traditional security 
issues affecting all tactical radios, the unique characteristics of 
JTRS radios have introduced new complexities into the certification 
process. First, because much of the functionality of JTRS radios is 
defined in software rather than in hardware, developers must be 
prepared to incorporate the features commonly required for computer 
security. Second, JTRS is required to operate in a networked 
environment, at multiple levels of security, and consequently allows 
greater access to other networks. Because this access increases the 
number of potential users and the likelihood of threats to the network, 
developers must be prepared to implement additional features required 
to maintain network security. According to NSA representatives, JTRS's 
open networking capability has raised the bar for ensuring that its 
security architecture is sound. 

The JPEO continues to identify security certification requirements as a 
significant risk element for the development of each variant of JTRS 
radios. For example, following the preliminary design review of the 
Ground Mobile Radio in July 2007, NSA informed the JPEO that certain 
aspects of the radio's security architecture did not meet the agency's 
standards. In response to these concerns, the JPEO is assessing 
potential design modifications to the radio and hopes to have an 
implementation plan in place later this year. The difficulties 
encountered in meeting security requirements also contributed to a 
significant Nunn-McCurdy unit-cost breach for the Ground Mobile Radio 
program that was declared in November 2007.[Footnote 10] The breach 
reflected an increase in the program acquisition unit cost of about 24 
percent above the current program cost baseline established in 2002. In 
addition, the need to address NSA security requirements has recently 
delayed the Multifunctional Information Distribution System-JTRS 
program. Although NSA concurred with the design of the system, the 
program encountered difficulties in meeting the requirements for 
security verification testing. This contributed to a program schedule 
slip of almost 12 months. 

Services Reconsidering Commitments to JTRS Because of High Costs and 
Continued Need for Legacy Radios: 

While JTRS radios are intended to provide a significant increase in 
communications and networking capabilities, they will be significantly 
more costly than the legacy radios they will replace. Depending on the 
JTRS product, estimated unit costs will range from an average of about 
$27,000[Footnote 11] for the Handheld, Manpack, and Small Form Fit 
radios to more than $1 million for the much larger maritime/fixed 
station radios. For some of the JTRS products, the costs are several 
times more than the legacy systems they will replace. For example, a 
fully configured vehicular version of the Army's SINCGARS radio costs 
about $20,000 and the Army's Enhanced Position Location Reporting 
System costs about $20,000 to $33,000 depending upon its configuration. 
In contrast, the average cost of the 4-channel vehicular configuration 
of the JTRS Ground Mobile Radio--which will be able to perform the 
function of both of these legacy radios and will add a transformational 
networking capability--is about $220,000. Similarly, according to 
AN/ARC-210 program office representatives, the latest generation of the 
1-channel AN/ARC-210 radio costs about $80,000, with most aircraft 
configured with two of the radios. In contrast, the average unit cost 
of the 2-channel airborne configuration of the JTRS radio is about 
$480,000. 

Moreover, to take full advantage of the new capabilities JTRS can 
provide, it must be integrated into existing military platforms. 
Integration costs, which are in addition to the cost of the JTRS radio 
itself, are borne by the integrating program and, according to Navy 
representatives, are most significant when attempting to fully 
integrate the networking capabilities of the JTRS radio into the 
mission avionics of legacy aircraft. Unlike ships, these aircraft do 
not have the computer architecture to easily incorporate modern 
networking capabilities. Consequently, fully integrating JTRS into 
legacy aircraft will require major modifications to both the hardware 
and software of the aircraft's mission avionic systems, as well as 
extensive testing and evaluation to ensure that the airworthiness of 
the aircraft has not been adversely affected. According to Navy 
representatives, the cost to retrofit and fully integrate JTRS 
networking capabilities into four Naval aircraft--the F/A-18E/F, EA- 
18G, E-2C, and E-2D--has been estimated to be about $868 million. Air 
Force representatives agreed that full integration of JTRS onto legacy 
aircraft would be very expensive. They noted, however, that as long as 
integration of JTRS occurs in conjunction with major modifications or 
modernization of these aircraft--during which mission avionic systems 
are upgraded and extensive airworthiness must be carried out--the 
incremental costs of integrating JTRS would be much less. 

While JTRS was originally intended to replace virtually all legacy 
radios, this is no longer a practical or affordable investment strategy 
for DOD and the services. JTRS is still critical to networking the 
force but the strategy of a wholesale replacement of radios is being 
reconsidered in light of the cost and availability of JTRS radios, the 
recent large investment in legacy radios, and the need to continue 
acquiring legacy radios in the near term. According to the services, 
the legacy radios purchased in the past several years provide effective 
communications capabilities to meet current operational demands. As 
these radios are expected to have an operating life of 10-15 years, the 
services expect to use a large proportion of them for many years to 
come. Absent JTRS radios, the services plan to continue purchasing 
legacy radios over the next several years because of continuing combat 
operations in Afghanistan and Iraq, and to implement plans to increase 
the size of the force. In January 2007, the President announced a 
permanent increase in the size of the Army and Marine Corps to enhance 
overall U.S. forces, reduce stress on deployable personnel, and provide 
more forces for the Global War on Terrorism. The planned expansion will 
add more than 74,000 soldiers to the Army by 2013 and 27,000 marines to 
the Marine Corps by 2011. 

DOD and the services have scaled back the number of JTRS radios they 
plan to buy (see table 2). For example, the total planned quantity of 
JTRS Ground Mobile Radios was recently reduced from 108,086 radios to 
86,512, a 20 percent decrease. While a portion of this decrease is due 
to the fact that several Army helicopter systems were originally to 
have received the Ground Mobile Radio variant but will now receive the 
Airborne, Maritime, and Fixed Station radio variant, the decrease is 
also due to the Marine Corps reducing its requirement to only 210 
radios. According to Marine Corps officials, they plan to continue 
investing in legacy radios and defer spending on fully capable JTRS 
radios until later. In addition, the total planned quantity of JTRS 
Handheld, Manpack, and Small Form Fit radios was recently reduced from 
an original baseline of 328,514--established in May 2004--to just 
95,551, a 71 percent decrease.

[End of table] 

Also, although the JTRS Airborne, Maritime, and Fixed-Station program 
was only recently approved to start system development, the number of 
required radios identified by the services is significantly lower than 
the number they initially identified when JTRS was restructured in 
2006--11,040 versus 17,007 radios. Part of this reduction is due to the 
Navy and Marine Corps no longer identifying a requirement for airborne 
radios and only a modest requirement for maritime/fixed station radios. 
According to Navy officials, the requirement for these radios has been 
deferred because of the high cost of the radios and because the 
airborne radio currently being developed will not include all the 
requirements desired by the Navy. The officials indicated that the JTRS 
restructuring in 2006 resulted in a scaled-down version of the airborne 
radio--with fewer channels and waveforms--that will not include voice 
capabilities. Voice is essential for pilots to be able to talk with 
other pilots and with ground control. Navy officials pointed out that 
while the JTRS airborne radios would provide enhanced networking 
capabilities, the lack of voice capabilities would necessitate keeping 
a legacy radio (e.g., the AN/ARC-210) in the aircraft and there would 
not be space for both radios. The Air Force plans to install the JTRS 
airborne radio primarily in larger aircraft that have space for 
multiple radios. 

The Joint Program Executive Office has begun to look at other options 
to acquire less expensive JTRS radios and other tactical radios. These 
efforts include: 

* The JTRS "Rifleman" Radio. This radio is being planned to meet an 
emerging Army need for a low-cost handheld soldier networking radio 
that can support intra-squad communications and provide position 
location information. The radio will be part of the JTRS small form 
factor family. Specifically, it will be acquired as a less expensive 
stand-alone variant of the small form factor "C" radio. Like the basic 
small form factor "C" radio, it is intended to be a 1-channel JTRS- 
compliant radio with networking capabilities that will support 
unclassified communications. However, to achieve significant cost 
savings, it is intended to rely on commercial (GPS) services, instead 
of military GPS services. The preliminary unit cost estimate for the 
radio is about $2,000, which is significantly less than the $8,700 unit 
cost of the small form factor "C" radio using military GPS. The Army 
has proposed an initial requirement for 100,000 or more of these 
radios.[Footnote 12] The Joint Program Executive Office hopes to begin 
production of the radio in 2009. 

* A 2-channel JTRS Ground Mobile Radio. Although the Army still needs 
the 4-channel Ground Mobile Radio for its Future Combat Systems, senior 
Army leadership has expressed concern about the high cost of JTRS 
Ground Mobile Radios for other components of the force. According to 
the Joint Program Executive Office, discussions are now under way with 
the Army about potential requirements trades that could be made, 
leading to a less expensive 2-channel Ground Mobile Radio variant. 

* An enhanced legacy 1-channel handheld radio. To address the services' 
need for near-term radios, the JPEO began offering an enhanced legacy 
handheld radio in 2007 that is capable of running multiple legacy 
waveforms, including SINCGARS, and meets NSA security modernization 
requirements. However, it does not provide the networking capabilities 
intended for JTRS handheld radios. The JPEO established a consolidated 
contract that provides two competing versions of the radio built by 
different contractors. In addition, the Office of the Assistant 
Secretary of Defense for Networks and Information Integration 
reinstated the waiver process for handheld radio procurements, 
requiring the services to obtain a waiver for purchasing radios outside 
of the consolidated contract. By consolidating purchases across the 
services in one contract and using competitively awarded delivery 
orders, the cost of these radios is lower than handheld radios 
purchased separately by each of the services.[Footnote 13] Furthermore, 
to meet the services' demand for manpack radios, the JPEO is now 
planning to acquire an enhanced manpack radio and provide it to the 
services through a consolidated contract with features similar to the 
contract for 1-channel handheld radios. 

DOD and the Services Lack a Comprehensive Strategy for Investments in 
Tactical Radios: 

Fielding JTRS judiciously without prematurely phasing out legacy radios 
will necessitate striking a balance between communications capabilities 
and available funding. DOD and the services, however, do not have a 
strategy to guide decisions on how best to proceed in acquiring 
tactical radios over the next several years--one that prioritizes 
capability needs, reconciles needs with bounded funding levels, defines 
an effective approach to fielding and sustaining tactical radios, and 
identifies contingencies for problems that may occur. Five years ago, 
DOD and the services had a migration strategy that was relatively 
straightforward--replace legacy radios as JTRS became available. Now, 
however, the market for new tactical radios is quite different and the 
services must balance the continued need for legacy radios with the 
desire to acquire the advanced networking capabilities expected with 
JTRS. In addition, whereas supplemental funding was readily available 
in the past to meet the demand for the huge increase in legacy radios, 
funding in the future may be more constrained. While supplemental 
budgets may be around for as long as operations continue in Afghanistan 
and Iraq, there is mounting pressure to bring non-war related spending 
into the normal budget process. 

In October 2003, shortly after JTRS was approved to begin system 
development, DOD and the services developed a joint migration plan for 
the transition from legacy radios to JTRS. The plan articulated key 
objectives for the program. It also identified the initial quantities 
of radios that the services planned to procure each year for fiscal 
years 2003 through 2012, and for 2013 and beyond, and the platform 
systems that would use JTRS. However, the plan was an interim document 
and contained numerous gaps, which the department planned to fill 
through refinement and periodic updating. For example, the plan 
provided very limited data linking needs to available and expected 
funding, and said nothing about associated integration costs. DOD had 
envisioned that the migration plan would be a "living and evolving 
document," which would be updated on a continuing basis and reviewed 
annually. As the plan became progressively more detailed, the 
department believed it would help to identify deficiencies where 
additional purchases of legacy systems might be required, and 
ultimately become a comprehensive roadmap for transitioning DOD to JTRS-
based networked communications. However, despite the department's plans 
to maintain a living document and the more complex environment that has 
arisen since it was put in place, the migration plan has not yet been 
updated. 

Each of the services has taken some steps to update its JTRS migration 
plan. Except for the Air Force, however, these efforts are either 
outdated or fall short in helping to identify how the services plan to 
achieve desired capabilities, balance near-and long-term needs, and 
prioritize funding. 

* The 2004 Navy migration plan provided detailed information on the 
legacy radios that would be replaced by JTRS sets, the platforms that 
those legacy radios supported, the number of legacy radios fielded, the 
estimated number of JTRS channels needed to replace the legacy radios, 
and yearly acquisition milestones from 2003 to 2020. The Navy plan also 
provided an estimate of how long legacy radios would be sustained. 

* The Air Force completed a relatively extensive JTRS migration plan in 
January 2007. In developing the plan, the Air Force used a 
prioritization scheme that assessed the availability, operational 
status, and suitability of various aircraft platforms for JTRS. The 
plan also identified near-term, mid-term, and long-term phases for 
achieving needed communications capabilities in terms of specific 
platforms, taking into account integration costs and planned 
procurement funding. 

* The Marine Corps' August 2007 Strategic Radio Plan provides high-
level information on plans to evolve from legacy to network-capable 
radios, but does not discuss specific quantities or platforms for 
migration into JTRS or funding that will be needed. 

* The Army has not yet developed a JTRS migration plan, but is in the 
process of doing so. Specifically, the basis of issue for the Army's 
JTRS requirements is currently being developed and is scheduled for 
completion later this year. According to Army officials, the basis of 
issue will map out the distribution of JTRS products, by type, for each 
brigade-sized unit within the Army. 

DOD has also begun to lay the foundation for an updated and more 
comprehensive JTRS fielding plan. Specifically, in May 2007 the Joint 
Staff's director for Command, Control, Communication, and Computer 
systems approved the first version of the Tactical Wireless Joint 
Network concept of operations. The network concept of operations seeks 
to evolve the JTRS concept of operations into an overarching concept 
document that will articulate the department's expectations for 
operational and tactical wireless capabilities. The first version 
primarily focuses on JTRS, but future versions are expected to 
incorporate additional joint programs and concepts in more detail. The 
development of the network concept of operations is an important first 
step, and is in line with our September 2006 recommendation [Footnote 
14] that the Secretary of Defense develop JTRS migration and fielding 
plans that are consistent with a well-developed concept of operations 
for using JTRS networking capabilities. 

The Office of the Assistant Secretary of Defense for Networks and 
Information Integration has also recently begun to develop a new JTRS 
migration and fielding plan and has requested each of the services to 
provide detailed information on JTRS and legacy radio requirements. The 
plan is intended to provide visibility into the migration to JTRS, as 
well as the status of the services' legacy radio inventories and 
related legacy radio procurements. The fielding plan would also serve 
as a data point for reporting to Congress, a tool for the Joint Staff's 
assessment of the supportability of the JTRS concept of operations, and 
a means to assess the services' compliance with the DOD radio 
acquisition policy. However, according to representatives from the 
Office of the Assistant Secretary, the input provided by the services 
has not been linked to operational architectures that define the 
communications and networking tasks and functions that are needed on 
the battlefield to enable simultaneous, interoperable operations. In 
addition, the services' input has lacked sufficient detail regarding 
current and future requirements, and funding priorities. As such, a 
comprehensive plan that balances needs with available resources, 
targets where investments in JTRS should be made, identifies 
contingencies in the event JTRS encounters further delays, and provides 
central direction for acquiring tactical radios over the next several 
years is still lacking. 

Conclusions: 

While weapon system investments are normally associated with major 
platforms such as aircraft and ships, DOD's investment in radios rivals 
the cost of some of its largest acquisition programs. As DOD looks 
ahead at its tactical radio investments over the next 5 years, it faces 
a less ambitious, yet more complicated undertaking than it did in 2003. 
DOD hopes to complete development and begin production of JTRS within 
the next few years. Yet, this is a down sized JTRS program that 
initially offers less capability than originally planned. Instead of 
being able to phase out old legacy radios as planned, DOD now faces a 
much larger inventory of relatively new legacy radios and improved 
interim radios with much useful life left in them. Phasing out these 
radios will necessarily be more deliberate given the huge costs already 
expended and the expected high price of JTRS sets. While much of the 
increased investment in radios since 2003 has been ad hoc, reactionary, 
and enabled by large supplemental budgets, this may have been 
unavoidable. However, this does not mean that the next 5 years should 
follow suit. Rather, DOD needs to regain control over tactical radio 
investments so that the best mix of capabilities can be procured with a 
judicious expenditure of funds. Having an investment strategy that 
establishes priorities, discipline, and contingency plans will be 
essential to making good decisions, particularly when predictability is 
elusive. While DOD and the services are making a series of decisions on 
a case-by-case basis to reconcile JTRS investments with lower-cost 
alternatives and relatively young legacy radio inventories, this 
approach could make future capabilities a product of such decisions 
rather than the strategic choice it should be. DOD does not have such a 
strategy today, and its previous migration plans and its waiver/ 
notification process have been overtaken by events. 

Recommendations for Executive Action: 

To improve DOD's ability to plan for and manage the development and 
fielding of tactical radios across the department, we recommend that 
the Secretary of Defense: 

* develop a comprehensive strategy and implementation plan for making 
sound investment decisions for tactical radios that: 

- is based on operational architectures that define the communications 
and networking functions needed on the battlefield, 

- assesses and prioritizes the capabilities and requirements needed in 
the near-and long-term, 

- sets bounds for the funding that will be committed to address these 
needs, 

- lays out an effective migration and fielding plan for delivering 
capabilities to the warfighter, and: 

- identifies contingencies in case there are further problems and 
delays with JTRS. 

We also recommend that the Secretary of Defense: 

* reinvigorate the tactical radio notification/waiver process to 
provide department wide insight into the continued procurement of 
legacy and interim radios. In doing so, consideration should be given 
to ensuring clear guidance and procedures are developed and 
communicated across the department. 

Agency Comments and Our Evaluation: 

In its letter commenting on the draft of our report, DOD agreed with 
our recommendations. DOD's letter is reprinted in appendix III. DOD 
noted that our report recommendations are consistent with the measures 
taken by the department to develop a comprehensive strategy and plan 
for optimizing investments in future systems, such as JTRS, while 
balancing the need for further investment in current systems. As we 
point out in the report, DOD has recently taken steps to develop a new 
migration and fielding plan for tactical radio systems. However, DOD 
did not provide any additional information on the measures it is taking 
that are consistent with our recommendations. It is important that the 
additional measures the Department does take provide a strategic basis 
for making investment decisions on tactical radios in the future. 
Specifically, the Department's plan needs to be linked to operational 
architectures, prioritize capability needs, set funding bounds, and 
identify contingencies to address potential delays with JTRS. 

DOD also provided detailed comments, which we incorporated where 
appropriate. 

We are sending copies of this report to the Chairmen and Ranking 
Members of other Senate and House committees and subcommittees that 
have jurisdiction and oversight responsibilities for DOD. We will also 
send copies to the Secretary of Defense; the Secretaries of the Air 
Force, Army, and Navy; and the Director, Office of Management and 
Budget. Copies will also be available at no charge on GAO's Web site at

Appendix I: Scope and Methodology: 

To assess how the services’ planned investments in key tactical radio 
systems changed over the last 5 years, we compared the services’ fiscal 
year 2003 to 2007 tactical radio procurement plans to actual 
procurements. To calculate the Army’s spending plans for tactical 
radios, we utilized the SINCGARS and Improved High Frequency Family of 
Radios budget line items. It is important to note that the Improved 
High Frequency Family of Radios budget line began in fiscal year 2005; 
prior to this date, the Army had been utilizing a combination of budget 
lines to procure handheld and manpack radios. To calculate Marine Corps 
plans for tactical radios we utilized the Radio Systems budget line, 
which includes a variety of radios. To determine the actual procurement 
of legacy radios between 2003 and 2007, we sent out a data call to 
service acquisition officers. For the Army, we obtained actual 
procurement information from the Program Manager Tactical Radio 
Communications System (PMO TRCS) in Fort Monmouth, N.J. For the Marine 
Corps, we obtained more accurate information from Headquarters Marine 
Corps Command, Control, Communications and Computers in Washington, 
D.C. through comments to our draft report. We were unable to obtain 
plans or actual procurement information from the Navy or Air Force. 
According to Navy and Air Force officials, these services do not 
centrally procure radios. 

To assess why tactical radio procurement plans changed, we reviewed and 
analyzed samples of tactical radio procurement waivers/notifications 
submitted to the Assistant Secretary of Defense for Networks and 
Information Integration (ASD NII) by the services. These waivers and 
notifications provide information as to why the procurements were 
needed. In addition, we interviewed officials from: Navy’s Program 
Executive Office Command, Control, Communications, Computers and 
Intelligence (PEO C4I) San Diego, California; Air Combat Electronics 
Program Office (PMA 209) Patuxent River, Md.; Office of the Chief of 
Naval Operations , Directorate for Communication Networks, Arlington, 
Va.; Marine Corps Combat Development Command, Quantico, Va.; Marine 
Corps Systems Command, Quantico, Va.; Army Aviation, Arlington, Va.; 
Office of the Army’s Deputy Chief of Staff, Arlington, Va.; Office of 
the Army’s Chief Information Officer, Washington, D.C.; Office of the 
Assistant Secretary of the Air Force for Acquisition, Rosslyn, Va.; and 
the Office of the Joint Chiefs of Staff, Arlington, Va. 

To determine what challenges will confront the services as they plan 
tactical radio investments to provide future capabilities, we obtained 
and analyzed briefings from JTRS program managers, reviewed the JTRS 
Board of Directors quarterly reports for the first and second quarters 
of fiscal year 2008, the 2003 JTRS joint migration plan, as well as 
service migration plans for the Air Force, Navy, and Marine Corps; 
reviewed the services’ estimates for future JTRS procurements and 
interviewed officials from the Office of the Under Secretary of Defense 
for Acquisition, Technology and Logistics; the National Security 
Agency; the Assistant Secretary of Defense for Networks and Information 
Integration; Office of the Army’s Deputy Chief of Staff (G-8); and the 
Office of the Chief of Naval Operations, Directorate for Air Warfare. 

We conducted this performance audit from July 2007 to July 2008 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.

Footnotes: 

[1] We were only able to identify tactical radio investments in Army 
and Marine Corps budget documents; we were unable to identify tactical 
radio investments for the Air Force and Navy as these services do not 
centrally procure radios. 

[2] In general usage, a waveform is the representation of a signal and 
the characteristics of a radio that includes the frequency, (VHF, HF, 
and UHF), modulation type (FM, AM), message format, and/or transmission 
system. Most of the radios used by the military services operate with a 
single waveform and can only interoperate with similar radios. However, 
several military radios have been developed in recent years that 
operate multiple waveforms. Thus, for example, if three waveforms are 
built into a radio, that single radio can emulate three different 
radios and be compatible with other radios that have these waveforms.

Congress when a program’s acquisition unit cost increases by at least 
15 percent over the current baseline estimate or increases by at least 
30 percent over the original baseline estimate. 

[11] Average procurement unit cost for all Handheld, Manpack, and Small 
Form Fit radios over the life of the program as reported in the 
December 2007 Selected Acquisition Report. The unit cost for these 
radios will vary significantly by form factor from about $6,000 for the 
least expensive small form fit radio, to about $38,000 for the Manpack 
radio. 

[12] This quantity is not reflected in the “Current Procurement 
Quantities” column in table 2. 

[13] An upgrading of the 1-channel radio is also under way to meet 
DOD’s revised standard for UHF satellite communications. In 2006, DOD 
established a requirement that the services migrate legacy UHF 
satellite communication systems from the Demand Assigned Multiple 
Access waveform to the more efficient Integrated Waveform. Efforts are 
now under way to add the Integrated Waveform to the 1-channel handheld 
radio.
