4258 AMS

The 4258th Aircraft Maintenance Squadron (4258 AMS) was a United States Air Force unit activated during the Vietnam War. Stationed at U-Tapao Royal Thai Navy Airfield, Thailand, the squadron was primarily responsible for the maintenance and support of B-52 Stratofortress bombers and KC-135 Stratotanker aircraft. The 4258 AMS played a critical role in sustaining the air operations of Strategic Air Command missions, including the intensive bombing campaigns of Operation Arc Light and Operation Linebacker. The unit was eventually inactivated in the mid-1970s as U.S. combat operations in Southeast Asia wound down.
