3525th OMS (ATC)

The 3525th Organizational Maintenance Squadron (OMS) was a unit under the Air Training Command (ATC) of the United States Air Force, stationed at Williams Air Force Base, Arizona. Activated in the late 1940s, its primary mission was to provide aircraft maintenance and support for pilot training operations, particularly for jet trainers such as the T-33 and later the T-37 and T-38. The squadron played a crucial role in ensuring the operational readiness and safety of training aircraft during the peak years of USAF pilot production in the Cold War era. The 3525th OMS was eventually inactivated in the early 1970s as part of a larger reorganization and drawdown of Air Training Command units.
