U.S. Air Force
The 20th Organizational Maintenance Squadron (OMS) was a unit of the United States Air Force assigned to Strategic Air Command (SAC). Stationed at Wurtsmith Air Force Base, Michigan, the 20th OMS provided vital maintenance and support for the 379th Bombardment Wing's fleet of B-52 Stratofortress bombers and KC-135 Stratotankers during the Cold War. The squadron ensured operational readiness through round-the-clock maintenance, playing a critical role in America's nuclear deterrence posture. The 20th OMS remained active until the closure of Wurtsmith AFB and the end of SAC operations in the early 1990s.
