564th SMS

The 564th Strategic Missile Squadron (SMS) was an intercontinental ballistic missile (ICBM) unit of the United States Air Force. Activated in 1960, it was assigned to Malmstrom Air Force Base in Montana as part of the 341st Strategic Missile Wing. The squadron was initially equipped with the Minuteman I and later upgraded to Minuteman II and Minuteman III missiles, playing a key role in America’s nuclear deterrent during the Cold War. The 564th SMS was deactivated in 2008 as part of ongoing missile force reductions.
