SAC-3909 Opns. Sqdn-Greenham Common England

The SAC-3909 Operations Squadron was a unit of the United States Air Force assigned to RAF Greenham Common in England during the Cold War. Activated in the early 1980s under Strategic Air Command (SAC), the squadron played a key role in operating and maintaining the Ground Launched Cruise Missiles (GLCM) as part of NATO’s nuclear deterrent in Europe. The unit was responsible for the security, readiness, and deployment of these missiles, contributing to the balance of power during a tense period of East-West relations. Following the signing of the Intermediate-Range Nuclear Forces (INF) Treaty in 1987, the mission of the 3909th wound down, and the squadron was inactivated as the missiles were withdrawn and the base closed in the early 1990s.
