The DSCS 3 satellite fleet
U.S. AIR FORCE FACT SHEET
Posted: Jan. 19, 2000
Currently, ten Phase 3 DSCS satellites operate in geosynchronous orbit at an altitude of more than 23,000 miles above the Earth. Each satellite utilizes six super high frequency transponder channels capable of providing worldwide secure voice and high rate data communications. DSCS 3 also carries a single channel transponder used for disseminating emergency action and force direction messages to nuclear capable forces.
The system is used for high priority communication such as the exchange of wartime information between defense officials and battlefield commanders. The military also uses DSCS 3 to transmit space operations and early warning data to various systems and users.
The next DSCS 3 launch is scheduled for January 2000. This will be the deployment of the first DSCS 3 System Life Enhancement Program (SLEP) satellite, utilizing 50 watt traveling wave tube amplifiers in all six channels, providing users with a 200 percent increase in tactical communications capability.
DSCS users operate on the ground, at sea or in the air. Members of Air Force Space Command units and the 50th Space Wing's 3rd Space Operations Squadron at Schriever Air Force Base, CO, provide satellite bus command and control for all DSCS satellites.
Air Force Materiel Commands Space and Missile Systems Center at Los Angeles Air Force Base, CA, is responsible for development and acquisition of DSCS satellites.
