Cape Canaveral LC31B


Minuteman launch silo. Complexes 31 and 32 were built between July 1959 and July 1960 to support the Air Force's Minuteman missile program. Each complex had one blockhouse and two launch pads. The two "A" pads were constructed as conventional flat pads, and the two "B" pads were built as ballistic missile silos. The sites were modified subsequently to support later versions of the Minuteman missile. In all, 92 Minuteman I, II and III missiles were launched from the complexes between 1 February 1961 and 15 December 1970.

Longitude: -80.5552 deg.
Latitude: 28.4515 deg.
First Launch: 1961.12.18.
Last Launch: 1969.09.23.
Number: 35 .

Associated Launch Vehicles
  • Minuteman 1A American intercontinental ballistic missile. Initial production version, 3 stage vehicle. The Minuteman IA used exclusively the Mk.5 RV with the W59 (1 MT) warhead. More...
  • Minuteman 1B American intercontinental ballistic missile. Full production version. Minuteman IB used the Mk.5 RV with the W59 (1 MT), the Mk.11 with the W56 (1.2 MT) and the Mk.11A with the W56 as well. More...
  • Minuteman 2 American intercontinental ballistic missile. US ICBM. 3 stage vehicle. The LGM-30F Minuteman II used the W56 warhead exclusively with either the Mk. 11B or Mk. 11C re-entry vehicle. More...
  • Minuteman 3 American four-stage solid-propellant intercontinental ballistic missile. In the 21st Century, the sole remaining US ICBM. 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...
