351st MSS

The 351st Missile Security Squadron (351st MSS) was an integral unit of the United States Air Force, activated to provide security for nuclear missile operations. Stationed at Whiteman Air Force Base, Missouri, the squadron protected Minuteman II intercontinental ballistic missile (ICBM) sites under the 351st Strategic Missile Wing during the Cold War. The 351st MSS ensured the physical security of missile silos, launch control facilities, and personnel, playing a crucial role in the nation’s strategic deterrence posture. Following the end of the Cold War and the subsequent deactivation of the 351st Strategic Missile Wing in the 1990s, the squadron was inactivated as part of the broader realignment of U.S. nuclear forces.
