Polar-Orbiting Operational Environmental Satellites: Restructuring Is Under Way, but Challenges and Risks Remain
GAO-07-910T: Published: Jun 7, 2007. Publicly Released: Jun 7, 2007.
The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is a tri-agency acquisition--managed by the Departments of Commerce and Defense and the National Aeronautics and Space Administration--which experienced escalating costs, schedule delays, and technical difficulties. These factors led to a June 2006 decision to restructure the program thereby decreasing its complexity,...
Space Acquisitions: Actions Needed to Expand and Sustain Use of Best Practices
GAO-07-730T: Published: Apr 19, 2007. Publicly Released: Apr 19, 2007.
DOD's space system acquisitions have experienced problems over the past several decades that have driven up costs by hundreds of millions, even billions of dollars, stretched schedules by years, and increased performance risks. DOD has recognized the need to change its approach to developing space systems and is attempting to instill best practices in new efforts. GAO was asked to testify on its f...
Defense Acquisitions: Space System Acquisition Risks and Keys to Addressing Them
GAO-06-776R: Published: Jun 1, 2006. Publicly Released: Jun 1, 2006.
On April 6, 2006, we testified before Congress on the Department of Defense's (DOD) space acquisitions. In fiscal year 2007, DOD expects to spend nearly $7 billion to acquire space-based capabilities to support current military and other government operations as well as to enable DOD to transform the way it collects and disseminates information, gathers data on its adversaries, and attacks targets...
Space Acquisitions: Improvements Needed in Space Systems Acquisitions and Keys to Achieving Them

Defense Space Activities: Continuation of Evolved Expendable Launch Vehicle Program's Progress to Date Subject to Some Uncertainty
GAO-04-778R: Published: Jun 24, 2004. Publicly Released: Jun 24, 2004.
The U.S. space policy states that access to and use of space is critical to preserving peace and protecting U.S. national security and also benefits the country's civil and commercial interests. Air Force guidance explains further that access to space requires the ability to launch critical space assets, when needed, by a mix of space launch systems from standard launch pads at major support facil...
Space Acquisitions: Committing Prematurely to the Transformational Satellite Program Elevates Risks for Poor Cost, Schedule, and Performance Outcomes
GAO-04-71R: Published: Dec 4, 2003. Publicly Released: Dec 4, 2003.
In a multibillion-dollar effort, the Department of Defense (DOD) plans to build a space-based communications system that leverages technologies never before used in space. Such a system would enable DOD to transform how information is collected on potential U.S. adversaries and how military forces are warned of hostile action. The backbone of this system will be the Transformational Satellite (TSA...
Military Space Operations: Planning, Funding, and Acquisition Challenges Facing Efforts to Strengthen Space Control
GAO-02-738: Published: Sep 23, 2002. Publicly Released: Sep 23, 2002.
The United States is increasingly dependent on space for its security and well being. The Department of Defense's (DOD) space systems collect information on capabilities and intentions of potential adversaries. They enable military forces to be warned of a missile attack and to communicate and navigate while avoiding hostile action. DOD's efforts to strengthen space control are targeted at seeking...
