The Corps operates rotary-wing, tiltrotor, and fixed-wing aircraft mainly to provide transport and close air support to its ground forces. Other aircraft types are also used in a variety of support and special-purpose roles. All Marine Corps aviation falls under the influence of the Deputy Commandant for Aviation, whose job is to advise the Commandant of the Marine Corps in all matters relating to aviation, especially acquisition of new assets, conversions of current aircraft, maintenance, operation, and command.

The Marine Air Command and Control System (MACCS) is the aviation command and control agencies of the United States Marine Corps that provide the Aviation Combat Element (ACE) commander with the means to monitor, supervise, and influence aviation operations in support of the Marine Air-Ground Task Force. The command and control agencies of the MACCS are provided by the squadrons and battalions of the Marine Air Control Groups that are present within each Marine Air Wing. The capabilities resident within the MACCS allow the MAGTF commander to safely conduct aviation operations, facilitate timely maneuver and prosecution of fires and ultimately retain full control of their entire area of operations. MACCS agencies are also responsible for coordinating Marine Corps aviation operations with joint, multinational and civil aviation.
