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...
Navy Ship Maintenance: Action Needed to Maximize New Contracting Strategy's Potential Benefits
GAO-17-54: Published: Nov 21, 2016. Publicly Released: Nov 21, 2016.
The Navy's Multiple Award Contract, Multi Order (MAC-MO) contracting strategy for ship repair offers a number of potential benefits compared to the former Multi Ship, Multi-Option (MSMO) contracting strategy, including increased competition. A key difference is that the MAC-MO strategy intends to control costs through the use of firm-fixed price contracts and the use of third-party planners, which...
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...
Presidential Helicopter: Program Progressing Largely as Planned
GAO-16-395: Published: Apr 14, 2016. Publicly Released: Apr 14, 2016.
Since 2014, the VH-92A presidential helicopter program has generally progressed as planned. Through November 2015, the contractor accomplished approximately $239.0 million (22 percent) in development work—leaving about $863.9 million (78 percent) in estimated work over the next 5 years. As of December 2015, the prime contractor had accomplished nearly all of the expected developmental tasks at o...
Defense Acquisitions: Assessments of Selected Weapon Programs
GAO-16-329SP: Published: Mar 31, 2016. Publicly Released: Mar 31, 2016.
Over the past year, the number of programs in the Department of Defense's (DOD) portfolio of major defense acquisitions increased from 78 to 79, while DOD's total planned investment in these programs decreased from $1.45 trillion to $1.44 trillion. This estimate is in line with a trend seen since 2010 of decreases in the portfolio's total acquisition cost. The portfolio's cost growth since first f...
Amphibious Combat Vehicle: Some Acquisition Activities Demonstrate Best Practices; Attainment of Amphibious Capability to be Determined
GAO-16-22: Published: Oct 28, 2015. Publicly Released: Oct 28, 2015.
Most of the current activities of the U.S. Marine Corps' Amphibious Combat Vehicle (ACV) program have demonstrated the use of best practices, but plans for an accelerated acquisition schedule pose potential risks. As the program approaches the start of engineering and manufacturing development, it is seeking to rely on mature technologies that have been demonstrated to work in their intended envir...
Trusted Defense Microelectronics: Future Access and Capabilities Are Uncertain
GAO-16-185T: Published: Oct 28, 2015. Publicly Released: Oct 28, 2015.
In April 2015, GAO found that the Department of Defense's (DOD) access to trusted leading-edge microelectronics faced challenging consequences stemming from manufacturing costs, supply chain globalization, and market trends, creating uncertainty regarding future access about U.S.-based microelectronics sources.Capital costs associated with producing leading edge microelectronics increase with each...
Defense Acquisitions: Joint Action Needed by DOD and Congress to Improve Outcomes
GAO-16-187T: Published: Oct 27, 2015. Publicly Released: Oct 27, 2015.
U.S. weapon acquisition programs often take significantly longer, cost more than promised and deliver fewer quantities and capabilities than planned. It is not unusual for time and money to be underestimated by 20 to 50 percent. As the Department of Defense (DOD) is investing $1.4 trillion to acquire over 75 major weapon systems as of March 2015, cost increases of this magnitude have sizeable effe...
GPS: Actions Needed to Address Ground System Development Problems and User Equipment Production Readiness
GAO-15-657: Published: Sep 9, 2015. Publicly Released: Sep 9, 2015.
The Air Force has experienced significant difficulties developing the Global Positioning System (GPS) next generation operational control system (OCX) and consistently overstated progress to the Office of the Secretary of Defense (OSD) compared to advisory independent assessments it received. It needs $1.1 billion and 4 years more than planned to deliver OCX due to poor acquisition decisions and a...
Evolved Expendable Launch Vehicle: The Air Force Needs to Adopt an Incremental Approach to Future Acquisition Planning to Enable Incorporation of Lessons Learned
GAO-15-623: Published: Aug 11, 2015. Publicly Released: Aug 11, 2015.
The Air Force intends to make significant changes to its acquisition approach for acquiring launch services under the Evolved Expendable Launch Vehicle (EELV) program which will alter its current access and insights into certain cost and performance data. The United Launch Alliance (ULA)—EELV's incumbent provider—currently provides national security space launch services under a cost-reimburse...
