FLTSATCOM-3 or Fleetsatcom-3 (FSC-3) was a communications satellite that was used by the United States Navy for communications between aircraft, ships, submarines and ground stations. Fleetsatcom 3 gave 30 voice and 12 teletypewriter communications channels simultaneously in the UHF band. The UHF up link was in the 290 to 320 MHz range while down link was in the 240 to 320 MHz range. A number of channels were reserved for high priority communications by the United States Air Force. These were ground to air communications between SAC aircraft, the E-3A airborne warning and control system and elements of the presidential command structure. FSC-3's life was officially ended in September 1995.
