Military Space Programs: Issues Concerning DOD's SBIRS and STSS Programs [January 4, 2006] [open pdf - 64KB]
"The Department of Defense's (DOD's) programs to develop new satellites to alert U.S. military commanders to foreign missile launches, and to support missile defense objectives, are controversial because of cost growth and schedule slippage. SBIRS [Space-Based InfraRed System]-High, managed by the Air Force, would replace existing Defense Support Program 'early warning' satellites. The Space Tracking and Surveillance System (STSS, formerly SBIRS-Low), managed by the Missile Defense Agency, would perform missile tracking and target discrimination for missile defense objectives. The SBIRS-High program has breached Nunn-McCurdy cost growth limits several times, and the program is being restructured again. This report will be updated."
