MDA’s BMDS is being designed to counter ballistic missiles of all ranges—short, medium, intermediate, and intercontinental.ballistic missiles have different ranges, speeds, sizes, and performance characteristics, MDA is developing multiple systems that when integrated provide multiple opportunities to destroy ballistic missiles before they can reach their targets. The BMDS architecture includes space-based and airborne sensors as well as ground- and sea-based radars; ground- and sea-based interceptor missiles; and a command and control, battle management, and communications system to provide the warfighter with the necessary communication links to the sensors and interceptor missiles. Table 1 provides a brief description of 10 BMDS elements and supporting efforts currently under development by MDA. MDA experienced mixed results in executing its fiscal year 2011 development goals and BMDS tests. For the first time in 5 years, we are able to report that all of the targets used in fiscal year 2011 test events were delivered as planned and performed as expected. In addition, the Aegis BMD program’s SM-3 Block IA missile was able to intercept an intermediate-range target for the first time. Also, the THAAD program successfully conducted its first operational flight test in October 2011. However, none of the programs we assessed were able to fully accomplish their asset delivery and capability goals for the year. See table 2 for how each of these programs met some of its goals during the fiscal year. Our report provides further detail on these selected accomplishments. Although some programs completed significant accomplishments during the fiscal year, there were also several critical test failures. These as well as a test anomaly and delays disrupted MDA’s flight test plan and the acquisition strategies of several components. Overall, flight test failures and an anomaly forced MDA to suspend or slow production of three out of four interceptors currently being manufactured. The Aegis BMD SM-3 Block IA program conducted a successful intercept in April 2011, but there was an anomaly in a critical component of the interceptor during the test. This component is common with the Block IB missile. Program management officials stated that the SM-3 Block IA deliveries have been suspended while the failure reviews are being conducted. The Aegis BMD SM-3 Block IB program failed in its first intercept attempt in September 2011. The Aegis program has had to add an additional flight test and delay multiple other flight tests. Program management officials stated that the SM-3 Block IB production has been slowed while the failure reviews are being conducted. The GMD program has been disrupted by two recent test failures. As a result of a failed flight test in January 2010, MDA added a retest designated as Flight Test GMD-06a (FTG-06a). However, this retest also failed in December 2010 because of a failure in a key component of the kill vehicle. As a result of these failures, MDA has decided to halt flight testing and restructure its multiyear flight test program, halt production of the interceptors, and redirect resources to return-to-flight activities. Production issues forced MDA to slow production of the THAAD interceptors, the fourth missile being manufactured. To meet the 2002 presidential direction to initially rapidly field and update missile defense capabilities as well as a 2009 presidential announcement to deploy missile defenses in Europe, MDA has undertaken and continues to undertake highly concurrent acquisitions. While this approach enabled MDA to rapidly deploy an initial capability in 2005 by concurrently developing, manufacturing, and fielding BMDS assets, it also led to the initiation of large-scale acquisition efforts before critical technologies were fully understood and allowed programs to move forward into production without having tests completed to verify performance. After delivering its initial capability in 2005, MDA continued these high-risk practices that have resulted in problems requiring extensive retrofits, redesigns, delays, and cost increases. While MDA has incorporated some acquisition best practices in its newer programs, its acquisition strategies still include high or elevated levels of concurrency that result in increased acquisition risk—including performance shortfalls, cost growth, and schedule delays—for these newer programs. Concurrency is broadly defined as overlap between technology development and product development or between product development and production of a system. This overlap is intended to introduce systems rapidly, to fulfill an urgent need, to avoid technology obsolescence, and to maintain an efficient industrial development and production workforce. However, while some concurrency is understandable, committing to product development before requirements are understood and technologies mature as well as committing to production and fielding before development is complete is a high-risk strategy that often results in performance shortfalls, unexpected cost increases, schedule delays, and test problems. At the very least, a highly concurrent strategy forces decision makers to make key decisions without adequate information about the weapon’s demonstrated operational effectiveness, reliability, logistic supportability, and readiness for production. Also, starting production before critical tests have been successfully completed has resulted in the purchase of systems that do not perform as intended. These premature commitments mean that a substantial commitment to production has been made before the results of testing are available to decision makers. Accordingly, they create pressure to avoid production breaks even when problems are discovered in testing. These premature purchases have affected the operational readiness of our forces and quite often have led to expensive modifications. In contrast, our work has found that successful programs that deliver promised capabilities for the estimated cost and schedule follow a systematic and disciplined knowledge-based approach, in which high levels of product knowledge are demonstrated at critical points in development.require an appropriate balance between schedule and risk and, in practice, programs can be executed successfully with some level of This approach recognizes that development programs concurrency. For example, it is appropriate to order long-lead production material in advance of the production decision, with the pre-requisite that developmental testing is substantially accomplished and the design confirmed to work as intended. This knowledge-based approach is not unduly concurrent. Rather, programs gather knowledge that demonstrates that their technologies are mature, designs are stable, and production processes are in control before transitioning between acquisition phases, which helps programs identify and resolve risks early. It is a process in which technology development and product development are treated differently and managed separately. Technology development must allow room for unexpected results and delays. Developing a product culminates in delivery and therefore gives great weight to design and production. If a program falls short in technology maturity, it is harder to achieve design stability and almost impossible to achieve production maturity. It is therefore key to separate technology from product development and product development from production— and thus avoid concurrency. A knowledge-based approach delivers a product on time, within budget, and with the promised capabilities. See figure 1 for depictions of a concurrent schedule and a schedule that uses a knowledge-based approach. To meet the 2002 presidential direction to initially rapidly field and update missile defense capabilities as well as the 2009 presidential announcement to deploy missile defenses in Europe, MDA has undertaken and continues to undertake highly concurrent acquisitions. Such practices enabled MDA to quickly ramp up efforts in order to meet tight presidential deadlines, but they were high risk and resulted in problems that required extensive retrofits, redesigns, delays, and cost increases. Table 3 illustrates concurrency in past efforts and its associated effects. Among earlier MDA programs, concurrency was most pronounced in the GMD program, where the agency was pressed to deliver initial capabilities within a few years to meet the 2002 presidential directive. The consequences here have been significant, in terms of production delays and performance shortfalls, and are still affecting the agency. In recent years, MDA has taken positive steps to incorporate some acquisition best practices, such as increasing competition and partnering with laboratories to build prototypes. For example, MDA took actions in fiscal year 2011 to reduce acquisition risks and prevent future cost growth in its Aegis BMD SM-3 Block IIA program. The agency recognized that the program’s schedule included elevated acquisition risks, so it appropriately added more time to the program by revising the schedule to relieve schedule compression between its subsystem and system-level design reviews. In addition, it incorporated lessons learned from other SM-3 variants into its development to further mitigate production unit costs. Moreover, for its PTSS program, MDA has simplified the design and requirements. However, table 4 shows that the agency’s current acquisition strategies still include high or elevated levels of concurrency that set many of its newer programs up for increased acquisition risk, including performance shortfalls, cost growth, and schedule delays. In our April 2012 report, we made two recommendations to strengthen MDA’s longer-term acquisition prospects. We recommended that the Secretary of Defense direct the Office of Acquisition Technology and Logistics to (1) review all of MDA’s acquisitions for concurrency and determine whether the proper balance has been struck between the planned deployment dates and the concurrency risks taken to achieve those dates and (2) review and report to the Secretary of Defense the extent to which the directed capability delivery dates announced by the President in 2009 are contributing to concurrency in missile defense acquisitions and recommend schedule adjustments where significant benefits can be obtained by reducing concurrency. DOD concurred with both of these recommendations. In addition, we recommended specific steps to reduce concurrency in several of MDA’s programs. DOD agreed with four of the five missile defense element-specific recommendations and partially agreed with our recommendation to report to the Office of the Secretary of Defense and to Congress the root cause of the SM-3 Block IB developmental flight test failure, path forward for future development, and the plans to bridge production from the SM-3 Block IA to the SM-3 Block IB before committing to additional purchases of the SM-3 Block IB. DOD commented that MDA will report this information to the Office of the Secretary of Defense and to Congress upon completion of the failure review in the third quarter of fiscal year 2012. However, DOD makes no reference to delaying additional purchases until the recommended actions are completed. We maintain our position that MDA should take the recommended actions before committing to additional purchases of the SM-3 Block IB.
