handle is hein.gao/gaocrptaula0001 and id is 1 raw text is: Acountabiiity * Integrity ReEabity Washington, DC 20548 August 2, 2007 The Honorable Bill Nelson Chairman The Honorable Jeff Sessions Ranking Member Subcommittee on Strategic Forces Committee on Armed Services United States Senate The Honorable Ellen Tauscher Chairwoman The Honorable Terry Everett Ranking Member Subcommittee on Strategic Forces Committee on Armed Services House of Representatives The Honorable Silvestre Reyes House of Representatives Subject: DOD is Making Progress in Adopting Best Practices for the Transformational Satellite Communications System and Space Radar but Still Faces Challenges The Department of Defense (DOD) is working to achieve information superiority over adversaries and share information seamlessly among disparate weapons systems. Two programs envisioned as a part of this effort are Transformational Satellite Communications System (TSAT) and Space Radar. TSAT is designed to provide rapid worldwide secure communications with air and space systems-including Space Radar-through radio frequency and laser communications links. Space Radar is expected to provide global all-weather intelligence, surveillance, and reconnaissance, particularly in denied areas, for military, national intelligence, and civil users. Both TSAT and Space Radar will require major software development efforts and employ a significant number of experienced staff. TSAT and Space Radar development efforts are expected to be among the most costly space systems ever developed by DOD. In 2004, TSAT was estimated to have a total life cycle cost of about $16 billion, of which $2.0 billion will have been spent at the end of fiscal year 2007. Space Radar is estimated to have a total life cycle cost from $20 billion to $25 billion, and the program has spent about approximately $464.5 million. TSAT expects to begin product development in fiscal year 2008, and launch the first satellite in the first quarter of fiscal year 2016. Space Radar expects to begin product development in fiscal year 2009 and launch the first satellite in third quarter of fiscal year 2016. The systems are also expected to be among the most complex ever developed, largely because of the challenges associated with integrating critical technologies within the satellites and networking the satellites to other platforms.
