The 320th Organizational Maintenance Squadron (OMS) was an integral support unit of the United States Air Force, primarily associated with the 320th Bombardment Wing. Activated during the Cold War era, the 320th OMS was responsible for the organizational-level maintenance of B-52 Stratofortress bombers and other assigned aircraft at Mather Air Force Base, California. The squadron ensured aircraft readiness by performing inspections, repairs, and servicing to support the wing’s strategic bomber operations. The 320th OMS contributed to the nation’s nuclear deterrence posture until its inactivation alongside the 320th Bombardment Wing in the early 1980s.
