552nd OM Sq (ADC)

The 552nd Operations Maintenance Squadron (OM Sq), Air Defense Command (ADC), was an Air Force unit responsible for the maintenance and operational support of aircraft and radar systems critical to continental air defense. Activated during the Cold War era, the squadron played a vital role in ensuring the readiness of airborne early warning and control assets, particularly those assigned to the 552nd Airborne Early Warning and Control Wing. The unit's personnel maintained the EC-121 Warning Star aircraft, which patrolled U.S. airspace to detect and track potential threats. The 552nd OM Sq contributed significantly to North American airspace security until advancements in technology and shifts in defense strategy led to its inactivation.
