Air Force Satellite Communications
The United States military's Air Force Satellite Communications (AFSATCOM) is a network of ground and space systems to allow rapid dissemination of communications to a worldwide audience. AFSATCOM's creation was during the height of the Cold War to guarantee that Emergency Action Messages would be received by Strategic Air Command nuclear forces. Operations
AFSATCOM operations used leased transponders off United States Navy Fleet Satellite Communications (FLTSATCOM) satellites for EAM transmission. See also
