ICBM Capabilities
America's ICBM team fulfills a critical role in maintaining global stability and ensuring the nation's safety and security. Up to 400 Minuteman III missiles provide a critical component of America's on-alert strategic forces. As the nation's "Unwavering Sentinel," the Airmen of Twentieth Air Force have remained on continuous, around-the-clock alert since 1959.  

The Minuteman III missiles are deployed over 33,600 square-miles of central Montana, western North Dakota, eastern Wyoming, western Nebraska and northern Colorado. They are dispersed in hardened silos to protect against attack and connected to 15 underground missile alert facilities through a system of hardened cables. Launch crews consisting of two officers perform around-the-clock alert in launch control centers. A variety of communication systems provide the President of the United States with highly reliable, virtually instantaneous and direct contact with each launch crew.

AFGSC is the Air Force's lead command for and largest operator of UH-1N Iroquois helicopters.  The UH-1N supports ICBM operations in missile fields controlled by F. E. Warren AFB, Malmstrom AFB and Minot AFB. 

Twentieth Air Force has a proud heritage as America's long-range strategic force. Activated April 4, 1944, the unit's B-29 Superfortresses bombed the Japanese Islands.  Twentieth Air Force bombers, Enola Gay and Bockscar, brought an early end to World War II after they dropped the first atomic bombs on Japan.  Twentieth Air Force units also supported United Nations' forces during the Korean War.  

Mar. 1, 1955 - Twentieth Air Force inactivated.

Sept. 1, 1991 - Twentieth Air Force reactivated as a component of the Strategic Air Command and was located at Vandenberg AFB, Calif.  Operationally responsible for all land-based Intercontinental Ballistic Missiles, Twentieth Air Force's rebirth came at a time when America's nuclear forces were entering a decade of unprecedented force reductions and changes.  Spawned by the Cold War's end and the breakup of the Soviet Union, these changes reshaped the basic fabric of this nation's nuclear deterrent forces.  For the men and women of America's ICBM Team, it proved to be a period of sustained, dramatic change. 

ICBM force structure was reduced radically as well during the 1990s, downsizing from six wings to three, and from 1,000 alert ICBMs to 550.  These drawdowns posed major leadership challenges for Airmen at all levels of command.   

June 1, 1992 - Strategic Air Command inactivated and the majority of SAC's assets, including Twentieth Air Force, transferred to the newly created Air Combat Command.  The new U.S. Strategic Command assumed combatant command of Twentieth Air Force's ICBMs. 

Jul. 1, 1993 - Twentieth Air Force transferred to Air Force Space Command and moved from Vandenberg AFB to
F. E. Warren AFB on 1 October 1993.  In the early 2000s, the deactivation of the 400th Missile Squadron at F.E. Warren AFB, Wyo. and the 564th Missile Squadron at Malmstrom AFB, Mont. brought the total number of on-alert ICBMs down to its current number of 450.  

Dec. 1, 2009 - Air Force Global Strike Command assumed control of Twentieth Air Force and the Air Force's Minuteman III ICBM mission.  

Oct. 1, 2015 - The 377th Air Base Wing at Kirtland AFB, N.M. transferred to Twentieth Air Force.
