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...
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...
Defense Acquisitions: Better Approach Needed to Account for Number, Cost, and Performance of Non-Major Programs
GAO-15-188: Published: Mar 2, 2015. Publicly Released: Mar 2, 2015.
The Department of Defense (DOD) could not provide sufficiently reliable data for GAO to determine the number, total cost, or performance of DOD's current acquisition category (ACAT) II and III programs. These non-major programs range from a multibillion dollar aircraft radar modernization program to soldier clothing and protective equipment programs in the tens of millions of dollars. GAO found th...
F-35 Sustainment: Need for Affordable Strategy, Greater Attention to Risks, and Improved Cost Estimates
GAO-14-778: Published: Sep 23, 2014. Publicly Released: Sep 23, 2014.
The Department of Defense (DOD) currently has or is developing several plans and analyses that will make up its overall F-35 sustainment strategy, which is expected to be complete in fiscal year 2019. The annual F-35 operating and support (O&S) costs are estimated to be considerably higher than the combined annual costs of several legacy aircraft (see fig.). DOD has begun some cost-savings efforts...
Defense Contracting: Early Attention in the Acquisition Process Needed to Enhance Competition
GAO-14-395: Published: May 5, 2014. Publicly Released: May 5, 2014.
The Department of Defense's (DOD) competition rate for all contract obligations declined over the past 5 fiscal years from 62 percent in fiscal year 2009 to 57 percent in fiscal year 2013, but remained flat for the past 2 years. In fiscal year 2013, the Army had the highest competition rate, 66 percent, while the Missile Defense Agency had the lowest competition rate, 29 percent. The 14 justificat...
Military Capabilities: Navy Should Reevaluate Its Plan to Decommission the USS Port Royal
GAO-14-336: Published: Apr 8, 2014. Publicly Released: Apr 8, 2014.
The Navy's 2013 report to Congress on the Port Royal 's material condition partially addressed congressional reporting requirements but has likely overstated modernization costs should the ship be retained in service. While the Navy acknowledges that it did not obtain an independent structural assessment as required by one of the mandates, the Navy found the condition of the ship to be comparabl...
Ford-Class Carriers: Lead Ship Testing and Reliability Shortfalls Will Limit Initial Fleet Capabilities
GAO-13-396: Published: Sep 5, 2013. Publicly Released: Sep 5, 2013.
The Navy faces technical, design, and construction challenges to completing Gerald R. Ford (CVN 78) that have led to significant cost increases and reduced the likelihood that a fully functional ship will be delivered on time. The Navy has achieved mixed progress to date developing CVN 78's critical technologies, such as a system intended to more effectively launch aircraft from the ship. In an ef...
Space Acquisitions: DOD Is Overcoming Long-Standing Problems, but Faces Challenges to Ensuring Its Investments Are Optimized
GAO-13-508T: Published: Apr 24, 2013. Publicly Released: Apr 24, 2013.
Most of the Department of Defense's (DOD) major satellite programs are in mature phases of development, that is, the initial satellites have been designed, fabricated, and launched into orbit while additional satellites of the same design are being produced. For the portfolio of major satellite programs, new cost and schedule growth is not as widespread as it was in prior years, but DOD is still e...
Department of Defense's Waiver of Competitive Prototyping Requirement for Combat Rescue Helicopter Program
GAO-13-313R: Published: Mar 7, 2013. Publicly Released: Mar 7, 2013.
DOD's rationale for waiving WSARA's competitive prototyping requirement for CRH addresses one of the two bases provided in the statute; namely that the cost of producing competitive prototypes exceeds the expected life-cycle benefits (in constant dollars) of producing the prototypes. The CRH program's acquisition strategy, which anticipates integrating an existing, in-production and flight-proven...
