321st MSS

The 321st Missile Security Squadron (321st MSS) was an integral unit of the United States Air Force, tasked with providing security for the intercontinental ballistic missile (ICBM) facilities at Grand Forks Air Force Base, North Dakota. Activated in the 1960s during the height of the Cold War, the squadron played a vital role in safeguarding the 321st Strategic Missile Wing’s Minuteman missile silos and associated assets. Personnel of the 321st MSS conducted continuous patrols, rapid response operations, and security assessments to maintain the integrity of the nation’s nuclear deterrent. The unit remained active until the 1990s, when the deactivation of the 321st Strategic Missile Wing led to its inactivation.
