The 93rd Field Maintenance Squadron (93rd FMS) was a vital support unit within the United States Air Force, originally assigned to the 93rd Bombardment Wing at Castle Air Force Base, California. Activated during the Cold War era, the 93rd FMS provided essential aircraft maintenance and logistical support for the wing's fleet of B-52 Stratofortress bombers and KC-135 Stratotankers. The squadron ensured the operational readiness and effectiveness of strategic bombing and aerial refueling missions, contributing to the United States' nuclear deterrence posture. The 93rd FMS was eventually inactivated following the restructuring and closure of Castle AFB in the early 1990s.
