78th Orgnl Maint Sq (ADC)
U.S. Marine Corps
The 78th Organizational Maintenance Squadron (78th Orgnl Maint Sq) was a unit assigned to the Air Defense Command (ADC) of the United States Air Force. Activated during the early years of the Cold War, the squadron provided vital organizational-level maintenance and support for the aircraft and equipment of its parent wing, ensuring operational readiness for air defense missions. Stationed at Hamilton Air Force Base, California, the 78th Orgnl Maint Sq supported interceptor squadrons tasked with protecting the western United States from potential aerial threats. The unit was eventually inactivated or redesignated as part of broader USAF structural changes in the later decades of the 20th century.
