MACS9 Beaufort Air Station
U.S. Marine Corps
Marine Air Control Squadron 9 (MACS-9) was a United States Marine Corps aviation command and control unit that was originally activated during World War II. The squadron's primary mission was to provide aerial surveillance, air traffic control, and air defense for Marine Corps aviation units. During the Cold War, MACS-9 was stationed at Marine Corps Air Station Beaufort, South Carolina, where it played a crucial role in supporting both training operations and readiness exercises. The unit contributed significantly to the development and implementation of radar and communication systems before it was eventually deactivated as part of force restructuring.
