Cape Canaveral LC25C


Trident, Poseidon launch complex. Complex 25 supported the U.S. Navy's submarine ballistic missile programs. Pads 25C and 25D were built in 1967 to support the Navy's Poseidon ballistic missile program. Seventeen Poseidons were launched from pads 25C and 25D between 16 August 1968 and 30 June 1970. Pad 25C supported the Cape's first Trident I ballistic missile launch on 18 January 1977. Seventeen more Trident I missiles were launched from Pad 25C between 15 February 1977 and 24 January 1979. Complex 25 was inactivated and dismantled in 1979.

Latitude: 28.4311 deg.
First Launch: 1968.08.16.
Last Launch: 1979.01.23.

Associated Launch Vehicles
  • Poseidon American submarine-launched ballistic missile. SLBM, 2 stages, inertial guided, nuclear MIRV warhead, range that of twice Polaris A-3. More...
  • Trident C-4 American intercontinental ballistic missile. 3 stages, inertial guided, warhead: nuclear MIRV. Could replace Poseidon in existing submarine launch tubes. More...

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
