Forces, Committee on Armed Services, House of Representatives: 

Why GAO Did This Study: 

For more than two decades, the Department of Defense (DOD) has invested 
heavily in space assets to provide the warfighter with mission-critical 
information. Despite these investments, DOD commanders have reported 
shortfalls in space capabilities. 

To provide tactical capabilities to the warfighter sooner, DOD recently 
began developing TacSats—a series of small satellites intended to be 
built within a limited time frame and budget—and pursuing options for 
small, low-cost vehicles for launching small satellites. 

GAO was asked to (1) examine the outcomes to date of DOD’s TacSat and 
small, low-cost launch vehicle efforts, (2) identify the challenges in 
pursuing these efforts, and (3) determine whether experiences with 
these efforts could inform DOD’s major space system acquisitions. 

What GAO Found: 

Through effective management of requirements and technologies and 
strong leadership, DOD was able to deliver the first TacSat satellite 
in 12 months and for less than $10 million. The Office of Force 
Transformation, TacSat 1’s sponsor, set requirements early in the 
satellite’s development process and kept them stable. DOD modified 
existing technologies for use in space, significantly reducing the 
likelihood of encountering unforeseen problems that could result in 
costly design changes. The satellite was also built within DOD’s 
science and technology environment, which enabled service laboratory 
scientists to address problems quickly, inexpensively, and 
innovatively. The vision and support provided by leadership were also 
key to achieving the successful delivery of TacSat 1. DOD has also made 
progress in developing three additional TacSats and is working toward 
developing a low-cost launch vehicle available on demand. 

Despite this achievement, DOD faces several challenges in providing 
tactical capabilities to the warfighter sooner. First, DOD has yet to 
develop a low-cost, small launch vehicle available to quickly put 
tactical satellites, including TacSat 1, into orbit. Second, limited 
collaboration between the science and technology and the acquisition 
communities—as well as the acquisition community’s tendency to expand 
requirements after program start—could impede efforts to quickly 
procure tactical capabilities. Securing funding for future TacSat 
experiments may also prove difficult because they are not part of an 
acquisition program. Finally, DOD lacks a departmentwide strategy for 
implementing these efforts, and because key advocates of the 
experiments have left DOD, it is unclear how well they will be 
supported in the future. 

Regardless of these challenges, DOD’s experiences with the TacSat 
experiments thus far could inform its major space system acquisitions. 
DOD’s approach to developing the TacSats—matching requirements to 
available resources, using proven technologies, and separating 
technology development from product development—reflects best 
commercial practices that lead to quicker delivery with less risk. 
According to some DOD officials, the TacSats and small, low-cost launch 
vehicles—once they are developed—could also provide an avenue for large 
space system acquisitions to prove out technologies in the space 
environment, something DOD has avoided because of the high cost of 
launching such experiments. These officials also believe that giving 
space professionals the opportunity to manage small-scale projects like 
TacSats may better prepare them for managing larger, more complex space 
system acquisitions. Finally, these officials noted that building small-
scale satellite systems and launch vehicles could create opportunities 
for small, innovative companies to compete for DOD contracts and 
thereby broaden the space industrial base. 

What GAO Recommends: 

GAO is recommending that DOD assign accountability for developing and 
implementing a departmentwide strategy for pursuing low-cost tactical 
capabilities—both satellite and launch vehicles—and identify 
corresponding funding. In commenting on the report, DOD agreed with the 
recommendation.

The Honorable Terry Everett: 
Chairman: 
Subcommittee on Strategic Forces: 
Committee on Armed Services: 
House of Representatives: 

Dear Mr. Chairman: 

Department of Defense (DOD) satellites and other space-related assets 
provide intelligence, surveillance, reconnaissance, missile warning, 
navigation, and other information critical to conducting military 
operations. DOD's space network is expected to play an increasingly 
important role in military operations. According to DOD, approximately 
70 percent of weapons used in Operation Iraqi Freedom were precision- 
guided--mostly through global positioning satellites. Yet in each major 
conflict over the past decade, senior military commanders reported 
shortfalls in space capabilities, such as those intended to provide 
imagery data. 

To address such shortfalls and provide tactical capabilities to the 
warfighter sooner, DOD recently began building a series of small 
satellites, referred to as TacSats, within the science and technology 
environment--an environment that lends itself to demonstrating 
technologies within a relatively short time frame and small budget. 
Although small satellites offer less performance than large satellites 
in areas like resolution, operational control, and power, the TacSats 
are expected to quickly provide the warfighter with the information 
needed to conduct operations in theater. DOD is also developing a 
small, low-cost launch vehicle that could be used to launch small 
satellites like the TacSats. 

Given the potential these efforts may offer in changing the way DOD 
does business, you asked us to (1) examine the outcomes to date from 
the TacSat experiments as well as from efforts to develop small, low- 
cost launch vehicles, (2) identify the challenges in pursuing TacSats 
and the launch vehicles, and (3) determine whether DOD's experiences 
with TacSats and small, low-cost launch vehicles could inform major 
space system acquisitions. 

To conduct our work, we interviewed DOD officials in the Office of 
Force Transformation, Air Force Space Command, Space and Missile 
Systems Center, the Air Force and Navy research labs, and in other 
cognizant offices, and analyzed documents obtained from these 
officials. We also interviewed industry representatives involved in 
developing large space systems and small commercial launch vehicles. We 
analyzed a number of GAO and DOD studies that discuss acquisition 
problems and associated challenges, including our work on best 
practices in weapon system development that we have conducted over the 
past decade. We conducted our review from June 2005 to March 2006 in 
accordance with generally accepted government auditing standards. For 
more on our scope and methodology, see appendix I. 

Results in Brief: 

DOD delivered the first TacSat satellite in 12 months and for less than 
$10 million.[Footnote 1] A number of elements enabled this achievement. 
First, the Office of Force Transformation, as TacSat 1's sponsor, 
effectively managed the satellite's requirements by reaching consensus 
on requirements early in the development process and keeping them 
stable. Second, DOD incorporated existing technologies and adapted them 
for new uses in space, significantly reducing the likelihood of 
encountering unforeseen problems that could result in costly design 
changes. Third, DOD built the satellite within the science and 
technology environment, enabling scientists at DOD's service labs to 
address problems quickly, inexpensively, and innovatively. Finally, DOD 
leadership provided a motivating vision, prompt funding, and high-level 
support throughout the experiment--a key factor in positioning new 
development efforts for success. DOD has made progress toward 
developing three additional TacSats--expected to be launched in May 
2007, summer 2007, and April 2008--and is working toward developing a 
low-cost launch vehicle. 

While DOD delivered the first TacSat on time and within its overall 
budget, the department faces several challenges in providing tactical 
capabilities to the warfighter sooner. First, while DOD is working to 
demonstrate a low-cost small launch vehicle to quickly put the tactical 
satellites into orbit, it has yet to deliver such a vehicle. As a 
result, TacSat 1 has not been launched. Second, the procurement of 
tactical capabilities in the future could be hindered if collaboration 
between the science and technology and acquisition communities is 
limited and the acquisition community expands requirements after 
program start--as has been the case in the past. Third, it may be 
difficult to secure continued science and technology funding for future 
TacSat experiments since they currently are not part of an acquisition 
program. Finally, DOD lacks a departmentwide strategy and leadership 
for implementing efforts in this area. Because key advocates of the 
experiments have left DOD, it is unclear how well the experiments will 
be supported in the future. 

DOD's experiences with TacSats thus far may inform major space system 
acquisitions, and some DOD officials and industry representatives 
believe there are potential long-term benefits. The approach to 
developing TacSats reflects best practices--managing requirements to 
match available resources, using relatively mature technologies, and 
keeping additional technology development separate from product 
development--that larger space system programs could emulate to achieve 
quicker delivery of more robust systems that meet program objectives 
with less risk. In addition, according to some DOD officials, the 
TacSats could provide an avenue for incremental capabilities as well as 
a venue for large space system acquisitions to prove out technologies 
in the space environment--something DOD has avoided because of the high 
cost of conducting such experiments. These officials also believe that 
giving space professionals the opportunity to manage small-scale 
projects like TacSats may better prepare them for managing larger, more 
complex space system acquisitions in the future. Finally, these 
officials noted that building small-scale satellite systems and launch 
vehicles could create opportunities for small, innovative companies to 
compete for DOD contracts and thereby broaden the space industrial 
base. 

To help ensure low-cost tactical capabilities continue to be developed 
and delivered to the warfighter quickly, we are recommending that DOD 
assign accountability for developing and implementing a departmentwide 
strategy for pursuing low-cost, responsive tactical capabilities--both 
satellite and launch--for the warfighter, and identify corresponding 
funding. In written comments on a draft of this report, DOD concurred 
with our findings and recommendation (DOD's letter is reprinted in app. 
II). 

Background: 

The TacSat experiments and efforts to develop small, low-cost launch 
vehicles are part of a larger DOD initiative: Operationally Responsive 
Space (ORS). In general, ORS was created by DOD's Office of Force 
Transformation (OFT) in response to the Secretary of Defense's 
instruction to create a new business model for developing and employing 
space systems. Under ORS, DOD aims to rapidly deliver to the warfighter 
low-cost, short-term joint tactical capabilities defined by field 
commanders--capabilities that would complement and augment national 
space capabilities, not replace them.[Footnote 2] ORS would also serve 
as a test bed for the larger space program by providing a clear path 
for science and technology investments, enhancing institutional and 
individual knowledge, and providing increased access to space for 
testing critical research and development payloads. ORS is a 
considerable departure from the approach DOD has used over the past two 
decades to acquire the larger space systems that currently dominate its 
space portfolio. These global multipurpose systems, which have been 
designed for longer life and increased reliability, require years to 
develop and a significant investment of resources.[Footnote 3] The slow 
generational turnover--currently 15 to 25 years--does not allow for a 
planned rate of replacement for information technology hardware and 
software. In addition, the data captured through DOD's larger space 
systems generally go through many levels of analysis before being 
relayed to the warfighter in theater. 

The TacSat experiments aim to quickly provide the warfighter with a 
capability that meets an identified need within available resources-- 
time, funding, and technology. Limiting the TacSats' scope allows DOD 
to trade off reliability and performance for speed, responsiveness, 
convenience, and customization. Once each TacSat satellite is launched, 
DOD plans to test its level of utility to the warfighter in theater. If 
military utility is established, according to a DOD official, DOD will 
assess the acquisition plan required to procure and launch numerous 
TacSats--forming constellations--to provide wider coverage over a 
specific theater. As a result, each satellite's capability does not 
need to be as complex as that of DOD's larger satellites and does not 
carry with it the heightened consequence of failure as if each 
satellite alone were providing total coverage. DOD currently has four 
TacSat experiments in different stages of development (see figure 1). 

Figure 1: Overview of TacSat Experiments: 

[See PDF for image] 

[End of figure] 

According to Naval Research Laboratory officials, TacSat 2's delay is 
primarily the result of overestimating the maturity of its main 
payload--an off-the-shelf imager that was being refurbished for space 
use. Officials also noted that the contracting process, which took 
longer than expected, used multiple and varied contracts awarded under 
standard federal and defense acquisition regulations. 

DOD is also using the TacSat experiments as a means for developing 
"bus" standards--the platform that provides power, attitude, 
temperature control, and other support to the satellite in space. 
Currently, DOD's satellite buses are custom-made for each space system. 
According to DOD officials, establishing bus standards with modular or 
common components would facilitate building satellites--both small and 
large--more quickly and at a lower cost. 

To achieve one of the TacSat experiments' goals--getting new 
capabilities to the warfighter sooner--DOD must secure a small, low- 
cost launch vehicle that is available on demand. Instead of waiting 
months or years to carry out a launch, DOD is looking to small launch 
vehicles that could be launched in days, if not hours, and whose cost 
would better match the small budgets of experiments. A 2003 Air Force 
study determined that DOD's current class of launchers--the Evolved 
Expendable Launch Vehicle--would not be able to satisfy these 
requirements. 

DOD Successfully Delivered First TacSat through Managing Requirements 
and Is Moving Forward with Additional Efforts: 

DOD delivered the TacSat 1 satellite within cost and schedule targets. 
To develop the first TacSat, DOD effectively managed requirements, 
employed mature technologies, and built the satellite in the science 
and technology environment, all under the guidance of a leader who 
provided a clear vision and prompt funding for the project. DOD is also 
moving forward with developing additional TacSats; bus standards; and a 
small, low-cost launch vehicle available on demand. 

TacSat 1's Development Approach Enabled Successful Delivery: 

In May 2004, 12 months after TacSat 1 development began, the Naval 
Research Laboratory delivered the satellite to OFT at a cost of about 
$9.3 million, thereby meeting its targets to develop the satellite 
within 1 year and an estimated budget of $8.5 million to $10 
million.[Footnote 4] Once TacSat 1 is placed into orbit, it is expected 
to provide capabilities that will allow a tactical commander to 
directly task the satellite and receive data over DOD's Secure Internet 
Protocol Router--a need identified by the warfighter. 

Figure 2: TacSat 1 Ready for Vibration Testing at Naval Research 
Laboratory: 

[See PDF for image] 

[End of figure] 

Before TacSat 1's development began, OFT and the Naval Research 
Laboratory worked together to reach consensus on known warfighter 
requirements that would match the cost, schedule, and performance 
objectives for the satellite. Our past work has found that when 
requirements are matched with resources, goals can be met within 
estimated schedule and budget. To inform the requirements selection 
process, the Naval Research Laboratory used an informal systems 
engineering approach to assess relevant technologies and determine 
which could meet TacSat 1 mission objectives within budget and 
schedule. Once TacSat 1's requirements were set, OFT did not change 
them. To meet its mission objectives, OFT sought a capability that 
would be "good enough" for the warfighter, given available resources-- 
rather than attempting to provide a significant leap in capability. OFT 
and the Naval Research Laboratory agreed to limit TacSat 1's 
operational life span to 1 year, which allowed the laboratory to build 
the satellite with lower radiation protection levels, less fuel 
capacity, and fewer backups than would have been necessary for a 
satellite designed to last 6 years or longer. 

The use of existing technologies for the satellite and the bus also 
helped to keep TacSat 1 on schedule and within cost. For example, 
hardware from unmanned aerial vehicles and other aircraft were modified 
for space flight to protect them in the space environment, and bus 
components were purchased from a satellite communications company. 
Using items on hand at the Naval Research Laboratory--such as the space 
ground link system transponder and select bus electronics--resulted in 
a savings of about $5 million. Using and modifying existing 
technologies provided the laboratory better knowledge about the systems 
than if it had tried to develop the technologies from scratch. 
According to a laboratory official, the TacSat 1 experiment also 
achieved efficiencies by using the same software to test the satellite 
in the laboratory and fly the satellite. 

Developing the TacSat within the science and technology environment 
also helped the experiment meet its goals. As we have stressed in our 
reports on systems development, the science and technology environment 
is more forgiving and less costly than the acquisition environment. For 
example, when engineers encountered a blown electronics part during 
TacSat 1's full system testing, they were able to dismantle the 
satellite, identify the source of the problem, replace the damaged 
part, and rebuild the satellite--all within 2 weeks of the initial 
failure. According to the laboratory official, this problem would have 
taken months to repair in a major space acquisition program simply 
because there would have been stricter quality control measures, more 
people involved, and thus more sign-offs required at each step. 
Moreover, the contracting mechanism in place at the Naval Research 
Laboratory allows the laboratory to respond quickly to DOD requests. 
Specifically, the center used several existing engineering and 
technical support contracts that are competed, generally, at 5-year 
intervals, rather than competing a specific contract for TacSat 1. 

According to a number of DOD officials, the ultimate success of the 
TacSat 1 procurement was largely the result of the former OFT director, 
who: 

* provided the original impetus and obtained support for the experiment 
from high levels within DOD and the Congress; 

* negotiated a customized mission assurance agreement with Air Force 
leaders to launch TacSat 1 from Vandenberg Air Force Base at a cost 
that was affordable given the experiment's budget; 

* empowered TacSat 1's project manager at the Naval Research Laboratory 
to make appropriate trade-off decisions to deliver the satellite on 
time and within cost; and: 

* helped OFT staff develop an efficient work relationship with the 
Naval Research Laboratory team and provided the laboratory with prompt 
decisions. 

DOD Is Working on Developing Future TacSats and Low-Cost Launch 
Vehicles: 

DOD is currently working on developing three additional TacSat 
experiments--along with bus standards--and a low-cost, on-demand launch 
vehicle. These efforts are generally in the early stages. DOD expects 
to launch TacSat 2--which began as an Air Force science and technology 
experiment and was altered to improve upon TacSat 1's capability--in 
May 2007. TacSat 3, which will experiment with imaging sensors, is in 
the development phase. TacSat 4, which will experiment with friendly 
forces tracking and data communication services, is in the design 
phase. Table 1 shows the development cost and schedule estimates and 
the target launch date for each satellite.

With TacSat 3, the Air Force began to formalize the process for 
evaluating and selecting potential capabilities for the TacSats, 
leveraging the experiences from the first two TacSats. The selection 
process, which currently takes 3 to 4 months, includes a presentation 
of capability gaps and shortfalls from the combatant commands and each 
branch of the military, and analyses of the suitability, feasibility, 
and transferability of the capabilities deemed the highest priority. 
According to DOD officials, this process allows the science and 
technology community to obtain early buy-in from the warfighter, 
thereby increasing the likelihood that requirements will remain stable 
and the satellite will have military utility. Obtaining warfighter 
involvement in this way represents a new approach for the TacSat 
series. See figure 3 for a more complete description of this evolving 
process. 

Figure 3: Capability Selection Process for TacSats 3 and 4: 

[See PDF for image] 

[End of figure] 

The Air Force has also begun to create plans for procuring TacSats for 
the warfighter should they prove to have military utility. The Air 
Force has developed a vision of creating TacSat reserves that could be 
deployed on demand, plans to establish a program office within its 
Space and Missile Systems Center, and plans to begin acquiring 
operational versions of successful TacSat concepts in 2010. 

DOD is also working to develop bus standards. Establishing bus 
standards would allow DOD to create a "plug and play" approach to 
building satellites--similar to the way personal computers are built. 
The service research labs, under the sponsorship of OFT, and the Space 
and Missile Systems Center are in the process of developing small bus 
standards, each using a different approach. The service labs expect to 
test some standardized components on the TacSat 3 bus, and system 
standards by prototyping a TacSat 4 bus. The Space and Missile Systems 
Center is also proposing to develop three standardized bus models for 
different-weight satellites, one of which may be suitable for a TacSat. 
The service labs expect to transition bus standards to the Space and 
Missile Systems Center in fiscal year 2008, at which time the center 
will select a final version for procurement for future TacSats. 

Both DOD and private industry are working to develop small, low-cost, 
on-demand launch vehicles. DOD's Defense Advanced Research Projects 
Agency (DARPA), along with the Air Force, established FALCON, a joint 
technology development program to accelerate efforts to develop a 
launch vehicle that meets these objectives. Through FALCON, DARPA 
expects to develop a vehicle that can send 1,000 pounds to low-earth 
orbit for less than $5 million with an operational cost basis of 20 
flights per year for 10 years. FALCON is expected to flight-test 
hypersonic technologies and be capable of launching small satellites 
such as TacSats. DARPA is currently pursuing two candidates for its 
FALCON launch vehicle--AirLaunch, a company that expects to launch 
rockets that have been ejected from the back of a C-17 cargo airplane, 
and SpaceX, whose two-stage launch vehicle will include the second U.S.-
made rocket booster engine to be developed and flown in more than 25 
years, according to the company's founder.[Footnote 5] DARPA could 
transition the AirLaunch concept to the Air Force after its 
demonstration launch in 2008. TacSat 1 is contracted to launch for 
about $7 million on SpaceX's vehicle. In addition, in 2005, the Air 
Force began pursuing a hybrid launch vehicle to support tactically and 
conventionally deployed satellites. The project is known as Affordable 
Responsive Spacelift, or ARES, and the Air Force has obtained internal 
approval to build a small-scale demonstrator that would carry 
satellites about two to five times larger than TacSats. 

DOD Faces Several Challenges in Pursuing Responsive Tactical 
Capabilities for Warfighters: 

DOD has several challenges to overcome in pursuing a responsive 
tactical capability for the warfighter. Although DOD and others are 
working to develop small, low-cost launch vehicles for placing 
satellites like the TacSats into space, such a vehicle has yet to be 
developed, and TacSat 1 has waited nearly 2 years since its completion 
to be launched. Transferring knowledge from the science and technology 
community to the acquisition community is also a concern, given that 
these two communities have not collaborated well in the past. Further, 
it may be difficult to secure funding for future TacSat science and 
technology projects since DOD allocates the majority of its research 
and development money to acquisition programs. Finally, there is no 
departmentwide vision or strategy for implementing this new capability, 
and the recent loss of leadership makes it uncertain to what extent 
efforts to develop low-cost, responsive tactical capabilities such as 
TacSats will continue to be pursued. 

DOD Has Yet to Provide a Low-Cost, Small Launch Vehicle: 

While DOD has delivered TacSat 1 on time and within budget, the 
satellite is not yet operational because it lacks a reliable low-cost-
-under $10 million--small launch vehicle to place it in orbit. TacSat 
1's original launch date was in 2004 on the SpaceX's first flight of 
its low-cost small launch vehicle. However, because of technical 
difficulties with the launch vehicle and launch facility scheduling 
conflicts, the TacSat 1 launch has been delayed 2 years and more than 
$2 million has been added to the total mission costs.[Footnote 6] 
SpaceX now plans to use a different small satellite for its first 
launch. 

* Placing satellites in orbit at a low cost has been a formidable task 
for DOD for more than two decades because of elusive economies of 
scale. There is a strong causal relationship between satellite 
capabilities and launch lift. As capabilities and operational life are 
added, satellites tend to become heavier, requiring a launch vehicle 
that can carry a heavier payload. With longer-lived satellites, fewer 
launches are needed, making per unit launch costs high. In addition, 
the high cost of a large launch vehicle can only be justified with an 
expensive, long-living multimission satellite. Ultimately, the high 
cost of producing a complex satellite has created a low tolerance for 
risk in launching the satellite and a "one shot to get it right" 
mentality. 

Over the past 10 years, DOD and industry have attempted to develop a 
low-cost launch vehicle. Three launch vehicles in DOD's inventory--the 
Pegasus, Taurus, and, to some extent, the Minotaur--were designed to 
provide space users with a low-cost means of quickly launching small 
payloads into low-earth orbit.[Footnote 7] DOD expected that relatively 
high launch rates, from both commercial and government use, would keep 
costs down, but the market for these launch vehicles did not 
materialize. For example, since its introduction in 1990, Pegasus has 
launched only 36 times, an average of 3 launches per year; Taurus has 
been launched only 7 times since it was introduced in 1994. The average 
cost of these launch vehicles is $16 million to $33 million. To provide 
another avenue for launching small satellites, the Air Force has 
proposed refurbishing part of its fleet of decommissioned 
intercontinental ballistic missiles--450 of which have been dismantled. 
The cost of retrofitting the missiles and preparing them for launch is 
about $18 million to $23 million. However, one Air Force official 
questioned whether these vehicles are too large for current TacSats. 

Some new developers in the space industry are cautiously optimistic 
about the small satellite market. For example, SpaceX signed seven 
contracts to launch various small satellites, including TacSat 1. 
Despite this optimism, SpaceX's first launch of its new vehicle has yet 
to occur--in part because it lacks a suitable launch facility. The 
launch facilities located in the United States cannot readily 
accommodate quick-response vehicles. Vandenberg Air Force Base--one of 
two major launch sites in the United States--has lengthy and detailed 
scheduling processes and strict safety measures for preparing for and 
executing a launch, making it difficult to launch a small satellite 
within a tight time frame and at a low cost.[Footnote 8] SpaceX's 
launch of TacSat 1 at Vandenberg was put on hold because of the 
potential risks it posed to a billion-dollar satellite that was waiting 
to be launched from a nearby pad. In addition, the Air Force licensed 
the use of another nearby pad at Vandenberg to a contractor for larger- 
scale launches. Given the proximity of the launch pads, SpaceX's 
insurance premium increased 10-fold, from about $50,000 to as much as 
$500,000, which added $2.3 million to TacSat 1's total mission costs. 
Because of these delays, SpaceX decided to carry a different 
experimental satellite on its first launch and to use a launch facility 
on Kwajalein Atoll, in the Pacific Ocean.[Footnote 9] The potential 
effect of changes--such as increased premiums or the need to transport 
satellites to distant locations--on efforts to keep costs low and 
deliver capabilities to the warfighter sooner is unknown. 

The Air Force is beginning to examine ways to better accommodate a new 
generation of quick-response vehicles. For example, Air Force officials 
are examining the feasibility of establishing a location on Vandenberg 
specifically for these vehicles that is separate from the larger launch 
vehicle pads. Officials are also assessing the suitability of other 
locations, such as Kodiak Island, for quickly launching small 
satellites. 

Procurement of TacSats by DOD's Acquisition Community May Be Hindered 
by Limited Transfer of Knowledge and Requirements Instability: 

To achieve a low-cost, on-demand tactical capability for the 
warfighter, the TacSat experiments will need to be transitioned into 
the acquisition community. We have previously reported that DOD's 
acquisition community has been challenged to maximize the amount of 
knowledge transferred from the science and technology community, and 
that DOD's science and technology and acquisition organizations need to 
work more effectively together to achieve desired outcomes. Many of the 
space programs we reviewed over the past several decades have incurred 
unanticipated cost and schedule increases because they began without 
knowing whether technologies could work as intended and invariably 
found themselves addressing technical problems in a more costly 
environment.[Footnote 10] Although DOD recently developed a space 
science and technology strategy to better ensure that labs' space 
technology efforts transition to the acquisition community, the 
acquisition community continues to question whether labs adequately 
understand acquisition needs in terms of capabilities and time frames. 
As a result, the acquisition community would rather use its own 
contractors to maintain control over technology development. 

According to DOD officials, action has been taken to improve the level 
of collaboration and coordination on the TacSat experiments. Officials 
from DOD laboratories involved in TacSats and acquisition communities 
agree that they are working better together on the experiments than 
they have on past space efforts. However, in pursuing a low-cost, on- 
demand tactical capability, the science and technology and acquisition 
communities have moved forward on somewhat separate tracks, and it is 
unclear to what extent the work and knowledge gained by the labs will 
be leveraged when the TacSat experiments are transferred to the 
acquisition community. For example, the Air Force and Navy labs are 
working to develop bus standards for the TacSat experiments that are 
scheduled to be transitioned to the Space and Missile Systems Center, 
the Air Force's acquisition arm, in fiscal year 2008. Yet, the Space 
and Missile Systems Center, working with the Aerospace Corporation, has 
proposed three different options for standardizing the bus. While two 
of the options are generally larger--and are intended for larger space 
assets--one of the proposed designs may be suitable for TacSats, 
although it will likely be costlier than a lab-generated counterpart. 

In addition, our past work has shown that DOD's space programs--as well 
as other large DOD programs--have been unable to adequately define 
requirements and keep them stable, and seldom achieve a match between 
resources and requirements at the start of the acquisition. One factor 
that contributes to poorly defined and unstable requirements is that 
space acquisition programs have historically attempted to achieve full 
capability in a single step and serve a broad base of users, regardless 
of the design challenge or the maturity of technologies. Given this 
track record, some DOD officials expressed concern over Space and 
Missile Systems Center's ability to adopt the TacSat approach of 
delivering capabilities that are good enough to meet a warfighter need 
within cost and schedule constraints. Air Force officials identified 
the center's organizational culture of risk avoidance and the 
acquisition process as two of the most significant barriers to 
developing and deploying space systems quickly. 

Short-Term Funding for Upcoming TacSats Uncertain: 

TacSats 1 and 2 have been fully funded within DOD, and TacSats 3 and 4 
were recently funded. However, funding is uncertain for TacSats beyond 
3 and 4. While the Congress added funding to DOD's 2006 budget to 
support TacSat efforts, such as developing bus standards, DOD did not 
request such funding. According to a DOD official, there would not be 
an effort to develop bus standards if funding had not come from the 
Congress. 

Historically, DOD's research and development budget has been heavily 
weighted to system acquisitions--80 percent of this funding goes to 
weapon system programs, compared with 20 percent going to science and 
technology. In addition, science and technology funding is spread over 
thousands of projects, while funding for weapon system programs is 
spread over considerably fewer, larger programs. This funding 
distribution can encourage financing technology development in an 
acquisition program. However, as we have previously reported, 
developing technologies within an acquisition program typically leads 
to cost and schedule increases--further robbing the science and 
technology community and other acquisition programs of investment 
dollars. 

Lack of DOD-wide Strategy and Loss of Leadership: 

DOD currently has no departmentwide strategy for providing a responsive 
tactical capability for the warfighter. Without such a strategy, it is 
unknown whether and to what degree there may be gaps or overlaps in 
efforts. DOD efforts to develop low-cost satellite and launch 
capabilities are moving forward under multiple offices at different 
levels (see table 2). 

Table 2: DOD Current Planning Efforts: 

DOD organization: National Security Space Office (primarily aligned 
with the Secretary of the Air Force as Executive Agent for Space); 
Planning action: Developing a responsive space investment architecture 
and road map. 

DOD organization: U.S. Strategic Command (primarily aligned with the 
Secretary of Defense via the Joint Chiefs of Staff); 
Planning action: Developing a joint capabilities document. 

DOD organization: Air Force Space Command (primarily aligned with U.S. 
Strategic Command); 
Planning action: 
* Developing four initial capabilities documents; 
* Planning for establishment of an acquisition office; 
* Developing Enabling Concept Document. 

DOD organization: Space and Missile Systems Center (primarily aligned 
with Air Force Space Command); 
Planning action: 
* Planning for establishment of an acquisition office; 
* Planning for establishment of an office that coordinates the 
transition of experiments to acquisition programs.

Since these efforts are occurring simultaneously, it is unclear how and 
if they will be used to inform one another. Moreover, there are 
different visions for the roles of low-cost, responsive satellites and 
launch vehicles in DOD's overall space portfolio. For example, one Air 
Force official stated his office is looking for direction from the 
Congress on how to move forward rather than from somewhere within DOD. 
Further, when interviewed, other Air Force officials were not in 
agreement over how the Air Force's vision for using TacSats fits in 
with OFT's proposed use of this capability for DOD. 

In addition to the lack of a DOD-wide strategy, the recent departure of 
key personnel may have created a gap in leadership, making it uncertain 
to what extent efforts to develop tactical capabilities such as TacSats 
will be pursued. As we reported in November 2005, program success 
hinges on whether leaders can make strategic investment decisions and 
provide programs with the direction or vision for realizing goals and 
alternative ways of meeting those goals.[Footnote 11] 

One official involved in developing the overall architecture described 
the pursuit of these capabilities as a "grassroots effort," 
underscoring the importance of having enthusiastic individuals involved 
in moving it forward. According to a number of DOD officials, the 
former OFT director was widely respected within and outside the agency 
and served as a catalyst for transformation across DOD, and was 
credited with championing and pursuing innovative concepts that could 
sustain and broaden military advantage. With the departure of the OFT 
director and other key advocates of the TacSat concept, service lab 
officials told us they are concerned about the fate of the TacSat 
experiments. DOD officials we spoke with acknowledged that there is no 
agreement on who should ultimately be responsible for deciding the 
direction of the TacSat experiments and other efforts to develop low- 
cost responsive tactical capabilities for the warfighter. 

Experiences with TacSats May Inform Major Space System Acquisitions and 
Lead to Long-Term Benefits: 

DOD's experiences developing a tactical capability for the warfighter 
through TacSats may be used to inform the way major space systems are 
acquired. Specifically, DOD's process for developing TacSat 1 reflects 
best practices that larger space system programs could employ to 
achieve better acquisition outcomes. In addition, some DOD officials 
believe that these efforts--focusing on delivering capabilities to the 
warfighter through TacSats and small, low-cost launch vehicles--could 
lead to long-term benefits, including providing opportunities for major 
space systems to test new technologies, enhancing the skills of DOD's 
space workforce, and broadening the space industrial base. 

Our past work has shown that commercial best practices--such as 
managing requirements, using mature technologies, and developing 
technology within the science and technology community--contribute to 
successful development outcomes. TacSat 1 confirms that applying these 
practices can enable projects to meet cost and schedule targets. While 
TacSat 1, as a small experimental satellite with only a few 
requirements, is much less complex than a major space system, we have 
reported that commercial best practices are applicable to major space 
system acquisitions and recommended that DOD implement them for such 
acquisitions. Despite our recommendation, DOD's major space system 
acquisitions have yet to consistently apply these best practices. 

* Manage requirements. DOD's major space acquisition programs have 
typically not achieved a match between requirements and resources 
(technology, time, and money) at program start. Historically, these 
programs have attempted to satisfy all requirements in a single step, 
regardless of the design challenge or the maturity of technologies 
needed to achieve the full capability. As a result, these programs' 
requirements have tended to be unstable--that is, requirements were 
changed, added, or both--which has led to the programs not meeting 
their performance, cost, and schedule objectives. We have found that 
when resources and requirements are matched before individual programs 
are started, programs are more likely to meet their objectives. One way 
to achieve this is through an evolutionary development approach, that 
is, pursue incremental increases in capability versus significant 
leaps. 

* Use mature technologies. DOD's major space acquisition programs 
typically begin product development before critical technologies are 
sufficiently matured, forcing the program to mature technologies after 
product development has begun. Our reviews of DOD and commercial 
technology development cases indicate that demonstrating a high level 
of maturity before new technologies are incorporated into product 
development puts those programs in a better position to succeed. 

* Develop technology within the science and technology environment. 
DOD's space acquisition programs tend to take on technology development 
concurrently with product development, increasing the risk that 
significant problems will be discovered late in development and that 
more time, money, and effort will be needed to fix these problems. Our 
reviews have shown that developing technologies separate from product 
development greatly minimizes this risk. 

DOD officials and industry representatives we spoke with also noted 
that some long-term benefits could result from focusing on delivering 
capabilities to the warfighter quickly. 

* First, small, low-cost, responsive satellites like the TacSats could 
augment major space systems--provided there is a means to launch the 
satellites. Because TacSats do not require significant investment and 
are not critical to multiple missions, the consequence of failure of a 
TacSat is low. In contrast, major space systems typically are large, 
complex, and multimission, and take many years to build and deliver. If 
a major space satellite fails, there are significant cost and schedule 
consequences. Ultimately, the already long wait time for the warfighter 
to receive improved capabilities is extended. 

* Second, developing small, low-cost launch vehicles could provide an 
avenue for testing new technologies in space. According to DOD 
officials, less than 20 percent of DOD's space research and development 
payloads make it into space, even while relying heavily on the National 
Aeronautics and Space Administration's Space Shuttle, which was most 
recently grounded for 2 ½ years. We recently reported that DOD's Space 
Test Program, which is designed to help the science and technology 
community find opportunities to test in space relatively cost- 
effectively, has only been able to launch an average of seven 
experiments annually in the past 4 years.[Footnote 12] According to 
industry representatives and DOD officials, efforts to develop a small, 
low-cost launch vehicle could improve the acquisition process because 
testing technologies in an operational environment could lower the risk 
for program managers by providing mature technologies that could be 
integrated into their acquisition programs. 

* Third, giving space professionals the opportunity to manage small- 
scale projects like TacSats from start to finish may better prepare 
them for managing larger, more complex space system acquisitions in the 
future. According to Navy and Air Force lab officials, managing the 
TacSat experiments has provided hands-on experience with the experiment 
from start to finish, unlike the experience provided to program 
managers of large systems at the Air Force Space and Missile Systems 
Center. 

* Finally, building low-cost, responsive satellites and launch vehicles 
could create opportunities for small, innovative companies to compete 
for DOD contracts and thereby increase competition and broaden the 
space industrial base. In April 2005, over 50 small companies sent 
representatives to the Third Responsive Space Conference, an effort 
hosted by a small private launch company. An industry representative 
stated that a number of small companies are excited about developing 
TacSats and small, low-cost launch vehicles and the potential to garner 
future DOD contracts, but he cautioned that it would be important to 
maintain a steady flow of work in order to keep staff employed and 
preserve in-house knowledge. Other industry representatives told Air 
Force officials that they are receiving mixed signals from the 
government regarding its commitment to these efforts--there has been a 
lot of talk about them, but relatively little funding. In addition, 
another industry representative stated that requirements must be 
contained; otherwise, costs will increase and eventually squeeze small 
companies back out of the business. 

Conclusions: 

For more than two decades, DOD has invested heavily in space assets to 
provide the warfighter with critical information needed to successfully 
conduct military operations. Despite this investment, DOD has been 
challenged to deliver its major space acquisitions quickly and within 
estimated costs. TacSat 1--an experimental satellite--has shown that by 
matching user requirements with available resources, using mature 
technologies, and developing technologies separate from product 
development, new tactical capabilities can be delivered quickly and at 
a low cost. By establishing a capabilities selection process, the 
TacSat initiative has also helped to ensure that future TacSats will 
address high-priority warfighter needs. At the same time, the TacSats 
may demonstrate an alternative approach to delivering capabilities 
sooner--that is, using an incremental approach to providing 
capabilities, rather than attempting to achieve the quantum leap in 
capability often pursued by large space systems, which leads to late 
deliveries, cost increases, and a high consequence of failure. By not 
optimizing its investment in TacSat and small launch efforts, DOD may 
fail to capitalize on a valuable opportunity to improve its delivery of 
space capabilities. As long as disparate entities within DOD continue 
moving forward without a coherent vision and sustained leadership for 
delivering tactical capabilities, DOD will be challenged to integrate 
these efforts into its broader national security strategy. 

Recommendation for Executive Action: 

To help ensure that low-cost tactical capabilities continue to be 
developed and are delivered to the warfighter quickly, we recommend 
that the Secretary of Defense assign accountability for developing and 
implementing a departmentwide strategy for pursuing low-cost, 
responsive tactical capabilities--both satellite and launch--for the 
warfighter, and identify corresponding funding.

Appendix I: Scope and Methodology: 

To assess the outcomes to date from the TacSat experiments and efforts 
to develop small, low-cost launch vehicles, we interviewed Department 
of Defense (DOD) officials in the Office of Force Transformation, 
Washington, D.C; Air Force Space Command, Peterson Air Force Base, 
Colorado; Space and Missile Systems Center, Los Angeles Air Force Base, 
California; Air Force Research Laboratory, Kirtland Air Force Base, New 
Mexico, and Wright-Patterson Air Force Base, Ohio; U.S. Naval Research 
Laboratory, Washington, D.C; and the Defense Advanced Research Projects 
Agency, Virginia, via written questions and responses. We also analyzed 
documents obtained from these officials. In addition, we interviewed 
industry representatives involved in developing large space systems and 
small commercial launch vehicles. 

To understand the challenges to DOD's efforts and to determine whether 
DOD's experiences with TacSats and small, low-cost launch vehicles 
could inform major space system acquisitions, we analyzed a wide body 
of GAO and DOD studies that discuss acquisition problems and associated 
challenges, including our work on best practices in weapon system 
development that we have conducted over the past decade. In addition to 
having discussions with officials at the Office of Force 
Transformation, the Air Force Space Command, the Space and Missile 
Systems Center, and the Air Force and Navy research labs, we spoke with 
officials from the National Security Space Office, Virginia, and the 
Force Structure, Resources, and Assessment Directorate of the Joint 
Chiefs of Staff, Washington, D.C. We conducted our review from June 
2005 to March 2006 in accordance with generally accepted government 
auditing standards.
