The Defense Satellite Communications System (DSCS) refers to
|“||[g]eosynchronous military communications satellites that provide high data rate communications for military forces, diplomatic corps, and the White House. The Defense Satellite Communications System provides long-haul super-high frequency 7/8 gigahertz voice and high data rate communications for fixed and transportable terminals, and extends mobile service to a limited number of ships and aircraft.||”|
"DSCS provides a GIG transmission backbone of high capacity C2, intelligence and multichannel communications service for the CCDRs, Services, and agencies. Although not formally considered part of the architecture's protected communications capabilities, DSCS has a credible antijam capability with sophisticated satellite survivability features. The satellites are nuclear-hardened, providing secure voice and high data rate, long-haul, worldwide communications. DSCS satellites support deployed forces and ships."
