The 93rd Organizational Maintenance Squadron (93rd OMS) was a unit of the United States Air Force assigned to the 93rd Bombardment Wing at Castle Air Force Base, California. Activated during the Cold War, its primary mission was to provide maintenance support for the wing’s fleet of B-52 Stratofortress bombers, ensuring their readiness for strategic deterrence operations. The 93rd OMS played a critical role in sustaining aircraft availability during major exercises and alert commitments throughout the 1950s to the 1990s. The unit was eventually inactivated as part of the post-Cold War drawdown and restructuring of Air Force strategic forces.
