1. McDonnell Douglas AV-8B Harrier II Marker
The First of Its Kind The McDonnell Douglas/Boeing AV-8B Harrier II evolved from the British Hakwer Siddeley Type Number P.1127 (1957). Together, the United Kingdom, United States and Germany funded the evaluation of nine development aircraft, known as Kestrels, in 1965 to investigate the value of tactical jet V/STOL (Vertical/Short Take-Off and Loading) operations. The first tactical jet V/STOL airplane to become operational, AV-8A Harriers first joined the Marine Corps in 1971, replacing their A-4s for close air support missions. The Harrier's V/STOL capability allowed it to support ground troops from nearby unimproved fields.
The AV-8B Harrier II became operational with the Marines in 1985. It featured extensive changes from the AV-8A, including a new supercritical composite wing, increased fuel capacity, a new cockpit similar to the F/A-18, new propulsion nozzles, a bubble canopy, and automatic stability control. The outrigger landing gear struts were moved inboard from the wingtips. The Marines are currently replacing their Harriers with the F-35B.
