MCAS Beaufort hosts all active duty USMC F/A-18 air operations on the East Coast. The mission of the Marine Corps Air Station, Beaufort is to provide support as an operational base for MAG-31 and the support units.
The mission of the Marine Aircraft Group (MAG-31) is to conduct anti-air-warfare and offensive air support operations in support of Fleet Marine Forces from advanced bases, expeditionary airfields, or aircraft carriers and conduct such other air operations as may be directed.
Currently, the Fightertown family consists of more than 700 marines and sailors, along with 600 civilian personnel who ensure that approximately 3,400 personnel of Marine Air Group 31 and its component squadrons and tenant units are readily deployable. Fighter Town's Hornet squadrons rotate overseas regularly, either for six-month training deployments to Marine Corps Air Station Iwakuni, Japan, as elements of Marine air-ground task forces, or aboard Navy aircraft carriers. At any given time, up to half the squadrons may be found at various points around the globe, and are routinely called into action when the Commander in Chief requires airborne strikes or support for ground forces.
