About this Unit
The 91st Field Maintenance Missile Squadron (FMMS) was a United States Air Force unit primarily responsible for the maintenance and support of intercontinental ballistic missiles (ICBMs) during the Cold War era. Stationed at Minot Air Force Base, North Dakota, the squadron played a crucial role in ensuring the operational readiness and reliability of the missile systems assigned to the 91st Strategic Missile Wing. Its personnel were highly trained in missile electronics, guidance systems, and warhead maintenance, directly contributing to the nation's strategic deterrence posture. The 91st FMMS was eventually reorganized and redesignated as part of broader Air Force restructuring efforts within the missile maintenance community.
