400th MMS

The 400th Munitions Maintenance Squadron (400th MMS) was an Air Force unit responsible for the storage, maintenance, and readiness of nuclear and conventional munitions during the Cold War era. Activated in the early 1960s, the squadron played a crucial role in supporting the Strategic Air Command’s deterrence mission, primarily at bases in Europe and the United States. Its highly trained personnel ensured the safety, security, and rapid deployment capability of strategic weapons systems. The 400th MMS was eventually inactivated or redesignated as the Air Force underwent organizational changes in the later decades of the 20th century.
