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...
Nuclear Weapons: NNSA Should Evaluate the Role of the Enhanced Surveillance Program in Assessing the Condition of the U.S. Nuclear Stockpile
GAO-16-549: Published: Sep 14, 2016. Publicly Released: Sep 14, 2016.
The Department of Energy's (DOE) National Nuclear Security Administration (NNSA) did not fully implement the Enhanced Surveillance Program as envisioned in the agency's 2007 Surveillance Transformation Project (2007 initiative) and has not developed a long-term strategy for the program. Surveillance is the process of inspecting a weapon through various tests of the weapon as a whole, the weapon's...
Arleigh Burke Destroyers: Delaying Procurement of DDG 51 Flight III Ships Would Allow Time to Increase Design Knowledge
GAO-16-613: Published: Aug 4, 2016. Publicly Released: Aug 4, 2016.
The Air and Missile Defense Radar (AMDR) program's SPY-6 radar is progressing largely as planned, but extensive development and testing remains. Testing of the integrated SPY-6 and full baseline Aegis combat system upgrade—beginning in late 2020—will be crucial for demonstrating readiness to deliver improved air and missile defense capabilities to the first DDG 51 Flight III ship in 2023. Afte...
DOD Service Acquisition: Improved Use of Available Data Needed to Better Manage and Forecast Service Contract Requirements
GAO-16-119: Published: Feb 18, 2016. Publicly Released: Feb 18, 2016.
Over the last 5 years, the Department of Defense (DOD) consistently obligated more on services than products. These obligations are significant. For example, in 2014 alone, DOD obligated $85 billion on its three largest types of services—knowledge-based, research and development, and facility-related services. This amount was more than double the amount DOD obligated for aircraft, land vehicles...
Missile Defense: Assessment of DOD's Reports on Status of Efforts and Options for Improving Homeland Missile Defense
GAO-16-254R: Published: Feb 17, 2016. Publicly Released: Feb 17, 2016.
The Department of Defense’s (DOD) August 2015 and September 2015 homeland missile defense reports generally met most of the required reporting elements from section 238 of the National Defense Authorization Act for Fiscal Year 2014 (FY14 NDAA) and section 1665 of the National Defense Authorization Act for Fiscal Year 2015 (FY15 NDAA), such as including descriptions of: the current and future ba...
Nuclear Weapons: NNSA Has a New Approach to Managing the B61-12 Life Extension, but a Constrained Schedule and Other Risks Remain
GAO-16-218: Published: Feb 4, 2016. Publicly Released: Feb 4, 2016.
The B61-12 life extension program's (LEP) managers have developed a management approach that officials from the Department of Energy's (DOE) National Nuclear Security Administration (NNSA) and the Department of Defense (DOD) regard as improved over the management approach used for past LEPs, which experienced schedule delays and cost overruns. Among other things, the B61-12 LEP is the first LEP to...
Ford Class Aircraft Carrier: Poor Outcomes Are the Predictable Consequences of the Prevalent Acquisition Culture
GAO-16-84T: Published: Oct 1, 2015. Publicly Released: Oct 1, 2015.
The Ford-class aircraft carrier's lead ship began construction with an unrealistic business case. A sound business case balances the necessary resources and knowledge needed to transform a chosen concept into a product. Yet in 2007, GAO found that CVN 78 costs were underestimated and critical technologies were immature—key risks that would impair delivering CVN 78 at cost, on-time, and with its...
Weapon System Acquisitions: Opportunities Exist to Improve the Department of Defense's Portfolio Management
GAO-15-466: Published: Aug 27, 2015. Publicly Released: Aug 27, 2015.
The Department of Defense (DOD) is not effectively using portfolio management to optimize its weapon system investments, as evidenced by affordability challenges in areas such as shipbuilding and potential duplication among some of its programs. Best practices recommend assessing investments collectively from an enterprise-wide perspective and integrating requirements, acquisition, and budget info...
DOE Project Management: NNSA Should Ensure Equal Consideration of Alternatives for Lithium Production
GAO-15-525: Published: Jul 13, 2015. Publicly Released: Jul 13, 2015.
The National Nuclear Security Administration's (NNSA) has identified various challenges in its lithium production strategy that may impact its ability to meet demand for lithium in the future, as well as actions that may mitigate these challenges. These challenges pertain to three key areas. First, NNSA may not have a sufficient supply of lithium material for defense program requirements. NNSA off...
Unmanned Carrier-Based Aircraft System: Navy Needs to Demonstrate Match between Its Requirements and Available Resources
GAO-15-374: Published: May 4, 2015. Publicly Released: May 4, 2015.
Since our last review in September 2013, the intended mission and required capabilities of the Navy's Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) system have come into question. Ongoing debate about whether the primary role of the UCLASS system should be mainly surveillance with limited strike or mainly strike with limited surveillance has delayed the program, as shown in t...
