About this Unit
The 432nd Munitions Maintenance Squadron (432nd MMS) was a United States Air Force unit primarily responsible for the storage, maintenance, and handling of munitions. Activated during the early years of the Cold War, the squadron played a vital role in supporting tactical fighter wings, notably the 432nd Tactical Reconnaissance Wing at bases such as Udorn Royal Thai Air Force Base during the Vietnam War. The 432nd MMS ensured the safe and effective delivery of ordnance for combat missions, contributing to U.S. air operations in Southeast Asia. The unit was eventually inactivated as part of broader force reductions and organizational changes post-Vietnam.
