Unmanned Carrier-Based Aircraft System: Debate over System's Role Led to Focus on Aerial Refueling
GAO-16-389R: Published: Mar 24, 2016. Publicly Released: Mar 24, 2016.
In 2015, the Department of Defense (DOD) conducted a review of its airborne intelligence, surveillance, and reconnaissance portfolio and debated the primary role of the Navy Unmanned Carrier-Launched Airborne Surveillance and Strike (UCLASS) system. As a result, DOD restructured the UCLASS program in its fiscal year 2017 budget submission to create the Carrier Based Aerial Refueling System (CBARS)...
F-35 Joint Strike Fighter: Preliminary Observations on Program Progress
GAO-16-489T: Published: Mar 23, 2016. Publicly Released: Mar 23, 2016.
GAO's ongoing work on the F-35 Joint Strike Fighter (F-35) program shows that the Department of Defense (DOD) has begun planning and funding significant new development work to add to the F-35's capabilities, an effort known as Block 4. The funding needed for this effort is projected to be nearly $3 billion over the next 6 years (see figure below), which would qualify it as a major defense acquisi...
Critical Defense Materials: Government Collected Data Are Sufficiently Reliable to Assess Tantalum Availability
GAO-16-335: Published: Mar 17, 2016. Publicly Released: Mar 17, 2016.
Data published by government and industry on the global supply of tantalum vary due to differences in forms of tantalum reported and data collection methods. For example, government data prepared by the United States Geological Survey (USGS) on tantalum production reports information on tantalum ore from mining. Industry data GAO obtained from the Tantalum-Niobium International Study Center includ...
Unmanned Aerial Systems: Further Actions Needed to Fully Address Air Force and Army Pilot Workforce Challenges
GAO-16-527T: Published: Mar 16, 2016. Publicly Released: Mar 16, 2016.
In April 2014, GAO reported on several issues the Air Force faced in managing its UAS pilots, and while the Air Force has taken some actions since then, it has not fully implemented GAO's recommendations to strengthen its management.Personnel Requirements : GAO reported that the Air Force had not accurately identified the number of UAS pilots required to accomplish its mission nor had it establish...
Defense Infrastructure: More Accurate Data Would Allow DOD to Improve the Tracking, Management, and Security of Its Leased Facilities
GAO-16-101: Published: Mar 15, 2016. Publicly Released: Mar 15, 2016.
While the Department of Defense (DOD) is taking some steps to address data issues, it cannot fully determine the number, size, and costs of its leases for real property because its Real Property Assets Database (RPAD), the real property inventory system that DOD uses to report on its leased assets, contains some inaccurate and incomplete data. GAO found that about 15 percent of the RPAD lease reco...
Defense Weather Satellites: Analysis of Alternatives Is Useful for Certain Capabilities, but Ineffective Coordination Limited Assessment of Two Critical Capabilities
GAO-16-252R: Published: Mar 10, 2016. Publicly Released: Mar 10, 2016.
The Department of Defense (DOD) conducted an analysis of alternatives (AOA) to identify and compare potential solutions to the department’s need for space-based environmental monitoring (SBEM) capabilities. DOD initiated the AOA in 2012—2 years after the cancellation of the National Polar-orbiting Operational Environmental Satellite System, intended to replace DOD’s existing Defense Meteorol...
Space Acquisitions: Challenges Facing DOD as it Changes Approaches to Space Acquisitions
GAO-16-471T: Published: Mar 9, 2016. Publicly Released: Mar 9, 2016.
Most major space programs have experienced significant cost and schedule increases. For instance, program costs for the Advanced Extremely High Frequency satellite program, a protected satellite communications system, have grown 116 percent as of our latest review, and its first satellite was launched more than 3 years late. For the Space Based Infrared System High, a missile warning satellite pro...
Modernizing the Nuclear Security Enterprise: NNSA's Budget Estimates Increased but May Not Align with All Anticipated Costs
GAO-16-290: Published: Mar 4, 2016. Publicly Released: Mar 4, 2016.
In the National Nuclear Security Administration's (NNSA) fiscal year 2016 budget materials, the estimates for efforts related to modernizing the nuclear weapons stockpile total $297.6 billion for the next 25 years—an increase of $4.2 billion (1.4 percent) in nominal dollar values (as opposed to constant dollar values) compared with the prior year's budget materials. However, for certain program...
Navy and Coast Guard Shipbuilding: Navy Should Reconsider Approach to Warranties for Correcting Construction Defects
GAO-16-71: Published: Mar 3, 2016. Publicly Released: Mar 3, 2016.
For five of the six Navy and Coast Guard ships GAO reviewed, guarantees did not help improve cost or quality outcomes. While the type and terms of each contract determine financial responsibility for correcting defects, the government, in most of the cases GAO examined, paid shipbuilders to repair defects. For the four ships with fixed-price incentive type contracts and guarantee clauses, the gove...
Federal Health Care Center: VA and DOD Need to Address Ongoing Difficulties and Better Prepare for Future Integrations
GAO-16-280: Published: Feb 29, 2016. Publicly Released: Feb 29, 2016.
The governance structure for the Captain James A. Lovell Federal Health Care Center (FHCC) demonstration—which includes leadership officials within the Departments of Veterans Affairs (VA) and Defense (DOD)—helped resolve collaboration problems with local leadership, but limitations with the FHCC's leadership selection and evaluation processes may impede future collaboration. For example, VA a...
