The 91st Operations Group (91 OG) is the operational component of the 91st Missile Wing, assigned to the Air Force Global Strike Command Twentieth Air Force. It is stationed at Minot Air Force Base, North Dakota.

The 91 OG is one of three USAF operational missile units, equipped with the LGM-30G Minuteman-III. Its mission is to defend the United States with safe and secure Intercontinental Ballistic Missiles (ICBMs); ready to immediately put bombs on target.

Activated as the World War II 91st Bombardment Group (Heavy), an Eighth Air Force B-17 Flying Fortress unit assigned to England, it was one of the first USAAF heavy bomb groups deployed to Europe in 1942. The 91st Bomb Group was stationed at RAF Bassingbourn and is most noted as the unit in which the bomber Memphis Belle flew, and for having suffered the greatest number of losses of any heavy bomb group in World War II.

As part of Strategic Air Command in the early years of the Cold War, the 91st Strategic Reconnaissance Group provided worldwide surveillance. Inactivated in 1952, the group was reactivated as the 91 OG in 1991. Its three missile squadrons, however, have no traditional link to the 91st Bombardment Group and were previously part of the 455th Strategic Missile Wing and 455th Bomb Group.

Through its five squadrons, the group remains a key facet of our nation's deterrent force. The five squadrons assigned to the group are the:

The Missile Squadrons include missile crewmembers, alert facility chefs and facility managers. These squadrons vigilantly maintain the missile force around-the-clock. Each squadron controls 50 launch facilities and five missile alert facilities. Missile squadrons are divided into missile operations flights and an operation support flight.
