432nd FMS

The 432nd Field Maintenance Squadron (FMS) was an integral support unit within the 432nd Tactical Reconnaissance Wing, primarily active during the Vietnam War era. Stationed at Udorn Royal Thai Air Force Base in Thailand, the 432nd FMS was responsible for the maintenance and repair of reconnaissance aircraft, notably the RF-4C Phantom II. The squadron ensured aircraft readiness for critical intelligence-gathering missions over Southeast Asia, contributing significantly to U.S. Air Force operational capabilities. Its technical expertise and round-the-clock support were vital to the wing's success until the unit’s inactivation as part of the post-war drawdown.
