Marine Fixed-wing Pilots fly some of the most advanced aircraft in the world. These officers perform essential functions of Marine Aviation—assault support, anti-air warfare, offensive air support, electronic warfare, control of aircraft and missiles, and aerial reconnaissance—to support missions around the world. Marine Rotary-wing and Tilt-rotor Pilots fly aircraft in coordination with ground forces to execute the missions of the Marine Corps. These officers and the aircraft they command may be ship-based or shore-based. Tilt-rotor Pilots' missions mirror that of Rotary-wing Pilots, combining transport capability with speed capability similar to that of Fixed-wing Pilots.
