351st Missile Wing LGM - 30 Minuteman Missile Launch Sites This is a list of the LGM - 30 Minuteman missile Missile Alert Facilities and Launch Facilities of the 351st Strategic Missile Wing , 20th Air Force , assigned to Whiteman AFB , Missouri . Overview . The 351st Strategic Missile Wing was the third United States Air Force LGM - 30 Minuteman ICBM wing , the second with the LGM - 30B Minuteman I . After the announcement on 14 June 1961 , there were second thoughts about the choice as original plans called for launchers to be spread into the Lake of the Ozarks region . Due to the terrain inaccessibility and the high water table , these plans were scrapped . Consequently , when the final approval came on 17 January 1962 , the launchers were placed in the vicinity of Whiteman AFB , making this the smallest Minuteman base with regard to area . Activated on 1 February 1963 , the 351st Strategic Missile Wing received its first Minuteman IB missile from the Boeing plant at Hill AFB , Utah , on 14 January 1964 . Soon the silos assigned to the three operational squadrons of wing were made operational . By 29 June 1964 , the last flight of missiles went on alert status , making the 351st a fully operational strategic missile wing . Beginning on 7 May 1966 , and throughout the rest of 1966 and into 1967 , the Air Force replaced the Minuteman IBs with LGM - 30F Minuteman II s . The completed transition in October 1967 gave the 351st SMW the distinction of being the first wing to complete the Force Modernization Program . The 28 September 1991 order from President Bush to take Minuteman II missiles off alert status ended the 351st ' s role as an active ICBM wing . Subsequently , the Air Force removed the wing ' s 150 Minuteman II missiles from service . The wing and its three squadrons of ICBMs were inactivated on 28 July 1995 . Under the START I treaty , the missiles were removed and the sites destroyed . The first silo was imploded on 8 December 1993 and the last on 15 December 1997 . Today , Whiteman AFB is the home of the 509th Bomb Wing and the B - 2 Spirit Stealth Bomber . One of the retired Minuteman IB is on display . In addition , the Oscar One ( O - 01 ) Missile Alert Facility ( MAF ) is now preserved as a museum . Of the 100 Minuteman LCFs built for the six Minuteman missile wings , this is the only one constructed on the support base itself . Active and retired military personnel with valid identification can tour the facility by contacting the 509th Bomb Wing Public Affairs office . Due to the ongoing " War on Terrorism " , it is closed to the general public . Facilities . The Missile Alert Facility ( MAF ) consists of a buried and hardened Launch Control Facility ( LCC ) and an above - ground Launch Control Support Building ( LCSB ) . MAFs were formerly known as Launch Control Facilities ( LCFs ) but terminology was changed in 1992 with the inactivation of Strategic Air Command ( SAC ) . In addition , a MAF has a landing pad for helicopters ; a large radio tower ; a large " top hat " HF antenna ; a vehicle garage for security vehicles ; recreational facilities , and one or two sewage lagoons . The entire site , except for the helicopter pad and sewage lagoons are secured with a fence and security personnel . About a dozen airmen and officers are assigned to a MAF . The underground LCC Launch Control Center ( LCC ) contains the command and control equipment for missile operations . It is staffed by the two launch officers who have primary control and responsibility for the 10 underground and hardened Launch Facilities ( LF ) s within its flight which contains the operational missile . Each of the five LCCs also has the ability to command and monitor all 50 LFs within the squadron . The LF is unmanned , except when maintenance and security personnel are needed . A squadron is composed of five flights ; flights are denoted by a letter of the alphabet with the facilities controlled by the flight being designated by a number , 01 through 11 , with 01 being the MAF .
