321 FMMS

The 321st Field Maintenance Squadron (321 FMMS) was a United States Air Force unit assigned to the 321st Strategic Missile Wing at Grand Forks Air Force Base, North Dakota. Activated during the Cold War, the squadron provided critical maintenance and logistical support for the wing's fleet of Minuteman intercontinental ballistic missiles. Personnel of the 321 FMMS were responsible for ensuring the operational readiness and reliability of missile systems, supporting America's strategic deterrence mission. The unit was inactivated in the 1990s following the end of the Cold War and the subsequent reduction in the nation’s ICBM force structure.
