The 4258th Field Maintenance Squadron (FMS) was a United States Air Force unit active during the Vietnam War era. Stationed at U-Tapao Royal Thai Naval Airfield in Thailand, the squadron provided critical maintenance support for B-52 Stratofortress bombers and KC-135 Stratotankers participating in Operation Arc Light and other Southeast Asia operations. The 4258th FMS ensured round-the-clock aircraft readiness, enabling sustained strategic bombing campaigns over Vietnam. The squadron was eventually inactivated in 1975 as U.S. operations in Southeast Asia drew down and the base was returned to the Thai government.
