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...
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...
Space Acquisitions: Space Based Infrared System Could Benefit from Technology Insertion Planning
GAO-15-366: Published: Apr 3, 2015. Publicly Released: Apr 3, 2015.
The Air Force assessed options for replacing older technologies with newer ones—called technology insertion—in the Space Based Infrared System (SBIRS) geosynchronous earth orbit (GEO) satellites 5 and 6. However, the assessment was limited in the number of options it could practically consider because of timing and minimal early investment in technology planning. The Air Force assessed the fea...
DOD Space Systems: Additional Knowledge Would Better Support Decisions about Disaggregating Large Satellites
GAO-15-7: Published: Oct 30, 2014. Publicly Released: Oct 30, 2014.
It is not yet known whether and to what degree disaggregation can help the Department of Defense (DOD) reduce acquisition costs and increase the resilience of its satellite systems. Experts GAO spoke with identified an array of benefits and limitations. For example, acquiring smaller, less complex satellites may require less time and effort to develop and produce. On the other hand, a larger numbe...
U.S. Launch Enterprise: Acquisition Best Practices Can Benefit Future Efforts
GAO-14-776T: Published: Jul 16, 2014. Publicly Released: Jul 16, 2014.
GAO has reported extensively on the Evolved Expendable Launch Vehicle (EELV) program in the past.In 2008, GAO reported that when the Department of Defense (DOD) moved the EELV program from the research and development phase to the sustainment phase in the previous year, DOD eliminated various reporting requirements that would have provided useful oversight to program officials and the Congress.In...
Environmental Satellites: Focused Attention Needed to Improve Mitigation Strategies for Satellite Coverage Gaps
GAO-13-865T: Published: Sep 19, 2013. Publicly Released: Sep 19, 2013.
National Oceanic and Atmospheric Administration (NOAA) has made progress on both the Joint Polar Satellite System (JPSS) and Geostationary Operational Environment Satellite-R series (GOES-R) programs, but key challenges remain to ensure that potential gaps in satellite data are minimized or mitigated. On the JPSS program, NOAA has made noteworthy progress in using Suomi National Polar-orbiting Par...
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...
Evolved Expendable Launch Vehicle: DOD Is Addressing Knowledge Gaps in Its New Acquisition Strategy [Reissued on August 13, 2012]
GAO-12-822: Published: Jul 26, 2012. Publicly Released: Jul 26, 2012.
The Department of Defense (DOD) has numerous efforts in progress to address the knowledge gaps and data deficiencies identified in the GAO report. Of the seven recommendations GAO made to the Secretary of Defense, two have been completely addressed. While two of GAO’s recommendations have actions underway that are expected to be completed, two recommendations need more action for completion and...
Polar Satellites: Agencies Need to Address Potential Gaps in Weather and Climate Data Coverage
GAO-11-945T: Published: Sep 23, 2011. Publicly Released: Sep 23, 2011.
Environmental satellites provide critical data used in weather forecasting and measuring variations in climate over time. In February 2010, the White House's Office of Science and Technology Policy disbanded the National Polar-orbiting Operational Environmental Satellite System (NPOESS)--a tri-agency satellite acquisition that had encountered continuing cost, schedule, and management problems--and...
Space Acquisitions: DOD Delivering New Generations of Satellites, but Space System Acquisition Challenges Remain
GAO-11-590T: Published: May 11, 2011. Publicly Released: May 11, 2011.
Despite decades of significant investment, most of the Department of Defense's (DOD) large space acquisition programs have collectively experienced billions of dollars in cost increases, stretched schedules, and increased technical risks. Significant schedule delays of as much as 9 years have resulted in potential capability gaps in missile warning, military communications, and weather monitoring...
