Download coordinates as: 41°07′59″N 104°52′01″W / 41.13306°N 104.86694°W / 41.13306; -104.86694 (Francis E. Warren AFB) 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.

In October 1962, construction began over an 8,300-square-mile (21,000 km2) area of Wyoming, Nebraska, and Colorado to build 200 Minuteman ICBM launch silos.

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.

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.

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.
