90th Operations Group

The 90th Operations Group is the operational component of the 90th Missile Wing of the United States Air Force. It is stationed at Francis E. Warren Air Force Base, Wyoming, and is assigned to Twentieth Air Force of Air Force Global Strike Command. The group is responsible for maintaining and operating on alert the wing's assigned LGM-30G Minuteman III intercontinental ballistic missiles.

The Air Force Historical Research Agency traces the unit's origins to the 90th Bombardment Group of the Second World War. From 1942-44 the 90th Bombardment Group flew Consolidated B-24 Liberators to bomb Japanese targets, operating from Australia and then New Guinea. It was awarded two United States Distinguished Unit Citations and the Philippine Presidential Unit Citation for its combat service in China, the Netherlands East Indies, New Guinea, the Bismarck Archipelago, Leyte, and Luzon. It was inactivated in the Philippines in early 1946.

The group was activated in July 1947 at Andrews Field, Maryland by Strategic Air Command (SAC), but appears not to have been manned before inactivating in September 1948. It was again activated by SAC at Fairchild Air Force Base in January 1951 and began equipping with Boeing B-29 Superfortress bombers, but a reorganization the following month reduced the group to paper status until it again inactivated in June 1952.
