90th Missile Wing LGM-30 Minuteman Missile Launch Sites
This is a list of the LGM-30 Minuteman missile alert and launch facilities of the 90th Missile Wing, 20th Air Force, assigned to Francis E. Warren Air Force Base, Wyoming.

Overview
The 90th Strategic Missile Wing (SMW) was the fifth United States Air Force LGM-30 Minuteman ICBM wing to be created (the fourth with the LGM-30B Minuteman I). In October 1962, construction began over an  area of Wyoming, Nebraska, and Colorado to build 200 Minuteman ICBM launch silos. On 1 July 1963, the Air Force activated the 90th SMW. The following year, the four component strategic missile squadrons activated 200 Minuteman missiles.

In November 1972, the Strategic Air Command (SAC) initiated the Minuteman Integrated Improvement Program to harden silos and upgrade command data buffers, allowing for quicker missile retargeting. Warren AFB also received new missiles: the Minuteman I ICBMs at the base were replaced with the LGM-30G Minuteman III between 1973 and 1975.

In November 1982, in a decision statement for Congress, President Ronald Reagan stated his plan to deploy the MX missile (later designated the LGM-118 Peacekeeper) to superhardened silos located at Warren AFB. In July 1984, construction began on Peacekeeper support facilities there. From 1986 through 1988, 50 Peacekeeper missiles were backfitted into silos formerly occupied by Minuteman IIIs of the 400th Strategic Missile Squadron. The 400th achieved initial operational capability with ten deployed Peacekeepers in December 1986; full operational capability was achieved in December 1988 with 50 missiles.

All of the 90th Wing's Minuteman III missile loads were reduced from three warheads to a single warhead by the START I treaty between 1991 and 2001. Beginning in 2002, the Peacekeepers began to be inactivated for budgetary reasons, and by September 2005, the 400th SMS had been inactivated.

The three active Minuteman III squadrons are commanded by the 90th Operations Group.

Facilities

The Missile Alert Facility (MAF) consists of a buried and hardened Launch Control Center (LCC) and an above-ground Launch Control Support Building (LCSB). MAFs were formerly known as Launch Control Facilities (LCFs) but the terminology changed in 1992 with the inactivation of the Strategic Air Command (SAC). In addition, a MAF has a helicopter landing pad, a large radio tower, a large "top hat" HF antenna; a garage for security vehicles; recreational facilities, and one or two sewage lagoons. The entire site, except for the helicopter pad and sewage lagoons, is secured with a fence and security personnel. About a dozen airmen and officers are assigned to a MAF.

The underground LCC contains the command and control equipment for missile operations. It is staffed by the two launch officers who have primary control and responsibility over the ten underground hardened Launch Facilities (LFs) within its flight; each contains an operational missile. Each of the five LCCs also has the ability to command and monitor all 50 LFs within the squadron. The LFs themselves are unmanned, except when maintenance and security personnel are needed there.

A squadron is composed of five flights, denoted by a letter of the alphabet; facilities controlled by the flight are designated by a number, 01 through 11, with 01 designating the MAF.
