KC-46 Tanker Modernization: Delivery of First Fully Capable Aircraft Has Been Delayed over One Year and Additional Delays Are Possible
GAO-17-370: Published: Mar 24, 2017. Publicly Released: Mar 24, 2017.
The Air Force's KC-46 modernization program—initiated to replace a third of its aging aerial refueling fleet—is meeting its cost and performance targets. With fewer engineering changes than expected, the program's estimated total acquisition cost has decreased about $7.3 billion, or 14 percent, since its initial estimate. However, the project remains behind schedule. Boeing—the prime contr...
Military Base Realignments and Closures: DOD Has Improved Environmental Cleanup Reporting but Should Obtain and Share More Information
GAO-17-151: Published: Jan 19, 2017. Publicly Released: Jan 19, 2017.
The Department of Defense (DOD) has captured and reported more comprehensive cost information in its environmental cost reporting for installations closed under the Base Realignment and Closure (BRAC) process since GAO last reported on the issue in 2007. For example, GAO reported in 2007 that the costs DOD reported for environmental cleanup for installations closed under the 2005 BRAC round were n...
Littoral Combat Ship and Frigate: Slowing Planned Frigate Acquisition Would Enable Better-Informed Decisions
GAO-17-279T: Published: Dec 8, 2016. Publicly Released: Dec 8, 2016.
The Navy's vision for the Littoral Combat Ship (LCS) program has evolved significantly over the last 15 years, reflecting degradations of the underlying business case. Initial plans to experiment with two different prototype ships adapted from commercial designs were abandoned early in favor of an acquisition approach that committed to numerous ships before proving their capabilities. Cost, schedu...
Joint Intelligence Analysis Complex: DOD Needs to Fully Incorporate Best Practices into Future Cost Estimates
GAO-17-29: Published: Nov 3, 2016. Publicly Released: Dec 5, 2016.
GAO assessed the cost estimate for the military construction project to consolidate and relocate the Joint Intelligence Analysis Complex (JIAC) at Royal Air Force (RAF) base Croughton and found that it partially met three and minimally met one of the four characteristics of a reliable cost estimate defined by GAO best practices, as shown in the table below. For example, it minimally met the credib...
Littoral Combat Ship and Frigate: Congress Faced with Critical Acquisition Decisions
GAO-17-262T: Published: Dec 1, 2016. Publicly Released: Dec 1, 2016.
The Navy's vision for Littoral Combat Ship (LCS) program has evolved significantly over the last 15 years, reflecting degradations of the underlying business case. Initial plans to experiment with two different prototype ships adapted from commercial designs were abandoned early in favor of an acquisition approach that committed to numerous ships before proving their capabilities. Ships were not d...
Depot Maintenance: Improvements to DOD's Biennial Core Report Could Better Inform Oversight and Funding Decisions
GAO-17-81: Published: Nov 28, 2016. Publicly Released: Nov 28, 2016.
The Department of Defense's (DOD) 2016 Biennial Core Report to Congress complied with two of the three reporting elements required by Section 2464—core capability requirements and planned workload. It partially complied with the third element—a detailed explanation or rationale for shortfalls and accompanying mitigation plans—because DOD did not include rationales and mitigation plans for al...
Weapon System Requirements: Detailed Systems Engineering Prior to Product Development Positions Programs for Success
GAO-17-77: Published: Nov 17, 2016. Publicly Released: Nov 17, 2016.
GAO's analysis of nine case studies identified four factors that frame the challenge posed by a given weapon system's requirements: acquisition approach, technology status, design maturity, and system interdependency. Systems engineering is the primary means for determining whether and how that challenge can be met. It is a disciplined learning process that translates requirements into specific de...
DOD Commissaries and Exchanges: Plan and Additional Information Needed on Cost Savings and Metrics for DOD Efforts to Achieve Budget Neutrality [Reissued on November 14, 2016]
GAO-17-38: Published: Nov 9, 2016. Publicly Released: Nov 9, 2016.
The Department of Defense's (DOD) May 2016 report on commissaries and exchanges does not provide a plan for achieving budget neutrality, which DOD interprets as ending the use of appropriated funding for commissaries and exchanges by October 2018. The report states that DOD will not be able to achieve budget neutrality, but does not provide detailed information on why budget neutrality is not poss...
Joint Intelligence Analysis Complex: DOD Partially Used Best Practices for Analyzing Alternatives and Should Do So Fully for Future Military Construction Decisions
GAO-16-853: Published: Sep 30, 2016. Publicly Released: Oct 31, 2016.
The Department of Defense's (DOD) decision to consolidate and relocate its Joint Intelligence Analysis Complex (JIAC) to Royal Air Force (RAF) base Croughton in the United Kingdom (U.K.) was influenced by the JIAC's current facilities' deteriorating condition and DOD criteria that guided its analysis of alternatives (AOA). DOD determined the current facilities are not well suited to the JIAC's mis...
Joint Information Environment: DOD Needs to Strengthen Governance and Management [Reissued on October 25, 2016]
GAO-16-593: Published: Jul 14, 2016. Publicly Released: Jul 14, 2016.
The Department of Defense (DOD) plans to spend almost $1 billion by the end of this fiscal year to implement one element of the Joint Information Environment (JIE); however, the department has not fully defined JIE's scope or expected cost. Officials reported that assessing the cost of JIE is complex because of the size and the complexity of the department's infrastructure and JIE's implementation...
