Over the last decade, DOD has been managing many challenging space systems acquisitions. A long-standing problem for the department is that program costs have tended to increase significantly from original cost estimates. In recent years, DOD has overcome many of the problems that had been hampering program development, and has begun to launch many of these satellites. However, the large cost growth of these systems continues to affect the department. Figure 1 compares the original cost estimates with current cost estimates for some of the department’s major space acquisition programs. The gap between the estimates in figure 1 represents money that the department was not planning to spend on these programs, and did not have available to invest in other efforts. The gap in estimates is fairly stable between fiscal years 2014-2018, a result of the fact that most programs are mature and in a steady production phase. This figure does not include programs that are still in the early stages of planning and development. In past reports, we have identified a number of causes of acquisition problems. For example, in past years, DOD has tended to start more weapon programs than is affordable, creating a competition for funding that focuses on advocacy at the expense of realism and sound management. DOD has also tended to start its space programs before it has the assurance that the capabilities it is pursuing can be achieved within available resources and time constraints. There is no way to accurately estimate how long it would take to design, develop, and build a satellite system when key technologies planned for that system are still in relatively early stages of discovery and invention. Finally, programs have historically attempted to satisfy all requirements in a single step, regardless of the design challenges or the maturity of the technologies necessary to achieve the full capability. DOD’s preference to make larger, complex satellites that perform a multitude of missions has stretched technology challenges beyond current capabilities in some cases. Our work has recommended numerous actions that can be taken to address the problems we identified. Generally, we have recommended that DOD separate technology discovery from acquisition, follow an incremental path toward meeting user needs, match resources and requirements at program start, and use quantifiable data and demonstrable knowledge to make decisions to move to next phases. We have also identified practices related to cost estimating, program manager tenure, quality assurance, technology transition, and an array of other aspects of acquisition program management that could benefit space programs. DOD has generally concurred with our recommendations, and has undertaken a number of actions to establish a better foundation for acquisition success. For example, we reported in the past that, among other actions, DOD created a new office within the Undersecretary of Defense for Acquisition, Technology and Logistics to focus attention on oversight for space programs and it eliminated offices considered to perform duplicative oversight functions. We have also reported in the past that the Air Force took actions to strengthen cost estimating and to reinstitute stricter standards for quality. Most of DOD’s major satellite programs are in mature phases of acquisition, and some of the significant problems of past years, such as cost and schedule growth, are not currently as prevalent. Table 1 describes the status of the space programs we have been tracking in detail. While many programs have overcome past problems, some of the major space programs have encountered significant challenges in the last year and some delays in development and production. For example: The Air Force’s Space Fence program office is developing a large ground-based radar that is expected to improve on the performance of and replace the Air Force Space Surveillance System, which became operational in 1961 and was recently shut down. The Space Fence radar will emit radio frequencies upward to space, from ground-based radar sites, to detect and track more and smaller Earth-orbiting objects than is currently possible, and provide valuable space situational awareness data to military and civilian users. The Air Force had originally planned to award a contract for Space Fence systems development in July 2012, but due to internal program reviews and budget re-prioritizations, this date has been delayed to May 2014. In addition, the number of radar sites planned has been reduced from two to one, though DOD plans to have an option under the system development contract to build a second site if needed. In April 2013, DOD proposed canceling the Missile Defense Agency’s Precision Tracking Space System (PTSS) because of concerns with the program’s high-risk acquisition strategy and long-term affordability. PTSS was intended to be a satellite system equipped with infrared sensors that would track ballistic missiles through their emitted heat. The planned satellite system would consist of a constellation of nine satellites in orbit around the earth’s equator. We reported in July 2013 that the decision to propose canceling the PTSS program was based on an evaluation of the acquisition, technical, and operational risks of the PTSS program. Specifically, DOD’s evaluation assessed the PTSS cost, schedule, technical design, and acquisition strategy to identify whether risks could challenge the program’s ability to acquire, field, and sustain the system within planned cost and schedule constraints. The evaluation also determined that the PTSS program had significant technical, programmatic, and affordability risks. The program officially ceased operations in October 2013. The Air Force has nearly completed its analysis of alternatives to determine the direction for space based environmental monitoring, which will be a follow-on program for the Defense Meteorological Satellite Program (DMSP). Through this analysis, the Air Force analyzed various options that included, but were not limited to, a traditional procurement of a weather satellite similar to the existing DMSP satellites, or a disaggregated approach using small satellites and hosted payload opportunities. According to the Air Force, the study was completed in the fall of 2013 and is awaiting final approval. The MUOS program plans to launch a third satellite in January 2015, which represents a delay of 6 months due to a production issue on the third satellite. Specifically, the third satellite failed system- and subsequent unit-level testing after rework last year and the program determined the root cause to be a manufacturing deficiency on a component critical for the operation of the satellite’s ultra-high- frequency legacy communications payload. The program is replacing the component. According to the MUOS program office, the program is on track to meet the launch schedule of subsequent satellites, which is important because most of the communications satellites that MUOS is replacing are past their design lives. Synchronizing deliveries of MUOS satellites with compatible Army Handheld, Manpack, Small Form Fit (HMS) terminals remains a challenge. Currently over 90 percent of the first satellite’s on-orbit capabilities are being underutilized because of terminal program delays. Consequently, military forces are relying on legacy communication terminals and are not able to take advantage of the superior capabilities offered by the MUOS satellites. Operational testing and initial fielding of MUOS-capable HMS terminals is planned for fiscal year 2014, with a production decision expected in September 2015. We have reported in the past that DOD and Congress are taking steps to reform and improve the defense acquisition system, and in the past year additional actions have been taken towards these goals. In November 2013, DOD published an update to its instruction 5000.02, which provides acquisition guidance for DOD programs. With this update, DOD hoped to create an acquisition policy environment that will achieve greater efficiency and productivity in defense spending. Air Force officials noted that, for satellite programs, there are two major changes that they believe will improve the acquisition process. First, the instruction was changed to formally allow satellite programs to combine two major program milestones, B and C, which mark the beginning of the development and production phases, respectively.Force, satellite programs have typically seen a great deal of overlap in the development and production phases, mainly because they are buying small quantities of items. They are often not able to produce a prototype to be fully tested because of the high costs of each article, so the first satellite in a production is often used both for testing and operations. Air Force officials believe that this change to the acquisition guidance will allow for streamlining of satellite development and production processes, and provide more efficient oversight without sacrificing program requirements. GAO has not assessed the potential effects of this change. In the past, we have reported that committing a program to production According to the Air without a substantive development phase may increase program cost and schedule risks, and we plan to look at the impacts of this change as it begins to be implemented. A second change made this year, according to Air Force officials, is the requirement that DOD programs, including space programs, undergo independent development testing. While development testing for DOD programs is not new to this policy revision, now the testing organization will be an independent organization outside the program office. For space programs, this organization will be under the Program Executive Officer for Space, and will report their findings directly to that office, providing what the Air Force believes will be an independent voice on a program’s development status. The Air Force is confident that these changes will provide benefits to program oversight, although because these are recent changes, we have not yet assessed their potential for process improvements. In addition, DOD is adopting new practices to reduce fragmentation of its satellite ground control systems, which adds oversight to a major development decision. Last year we reported that DOD’s satellite ground control systems were potentially fragmented, and that standalone systems were being developed for new satellite programs without a formal analysis of whether or not the satellite control needs could be met with existing systems. In the National Defense Authorization Act for Fiscal Year 2014, Congress placed more oversight onto this process by requiring a cost-benefit analysis for all new or follow-on satellite systems using a dedicated ground control system instead of a shared ground This new requirement should improve oversight into control system.these systems’ development, and may reduce some unnecessary duplication of satellite control systems.
