This system will provide 50-state defense for the United States and will consist of a limited number of ground-based interceptor missiles, ground-based radars, upgraded early warning radars, space-based sensors, and a battle management, command and communications system. Pratt & Whitney Space Propulsion developed and qualified the Orbus 1 booster in 1988 for the third stage of the Army Strategic Defense Command’s Strategic Target System (STARS). Subsequently, Sandia National Laboratory, the United States Army Space and Missile Defense Command, and the Ballistic Missile Defense Organization also selected the Orbus 1 motor for Stages 3 and 4 of their Starbird vehicle. In addition to defense programs, Orbus 1 is well suited for commercial space launch and satellite applications as a small launch vehicle upper stage or satellite apogee kick vehicle. Orbus 1 has a perfect performance record on seven full-scale static firings and nine flight missions.
