Associated Launch Vehicles
  • Trident C-4 American intercontinental ballistic missile. 3 stages, inertial guided, warhead: nuclear MIRV. Could replace Poseidon in existing submarine launch tubes. More...
  • Trident American submarine-launched ballistic missile. US Navy submarine-launched ballistic missiles, which superseded the Polaris. More...
  • Trident D-5 American intercontinental range, submarine-launched ballistic missile. Deployed March 1990 aboard the new Ohio-class submarines. 336 remain in service in the 2010's as America's seaborne nuclear deterrent. 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...
  • Vandenberg Vandenberg Air Force Base is located on the Central Coast of California about 240 km northwest of Los Angeles. It is used for launches of unmanned government and commercial satellites into polar orbit and intercontinental ballistic missile test launches toward the Kwajalein Atoll. More...
