McDonnell Douglas AV-8B Harrier II · 模型 165438
The McDonnell Douglas AV-8B Harrier II is a single-engine ground-attack aircraft that constitutes the second generation of the Harrier family, capable of vertical or short takeoff and landing (V/STOL). The aircraft is primarily employed on light attack or multi-role missions, ranging from close air support of ground troops to armed reconnaissance. The AV-8B is used by the United States Marine Corps, the Spanish and Italian Navies. A variant of the AV-8B, the British Aerospace Harrier GR.5, was developed for the Royal Air Force, while another, the TAV-8B, is a dedicated two-seat trainer. The project that eventually led to the AV-8B's creation started in the early 1970s as a cooperative effort between the United States and United Kingdom, aimed at addressing the operational inadequacies of the first-generation Hawker Siddeley Harrier. Early efforts centered on a larger, more powerful Pegasus engine to dramatically improve the capabilities of the Harrier. Because of budgetary constraints, the UK abandoned the project in 1975. Following the UK's withdrawal, McDonnell Douglas extensively redesigned the earlier AV-8A Harrier to create the AV-8B. While retaining the general layout of its predecessor, the aircraft incorporates a new, larger composite wing with an additional hardpoint on each side, an elevated cockpit, a redesigned fuselage and other structural and aerodynamic refinements. The aircraft is powered by an upgraded version of the Pegasus. The AV-8B made its maiden flight in November 1981 and entered service with the USMC in January 1985. Later upgrades added a night-attack capability and radar, resulting in the AV-8B (Night Attack) and AV-8B Harrier II Plus versions, respectively. An enlarged version named Harrier III was also studied but not pursued. The UK, through British Aerospace, re-joined the improved Harrier project as a partner in 1981, giving it a significant work-share in the project. Following corporate mergers in the 1990s, Boeing and BAE Systems have jointly supported the program. Approximately 340 aircraft were produced in a 22-year production program that ended in 2003. Typically operated from small aircraft carriers, large amphibious assault ships and simple forward operating bases, AV-8Bs have participated in numerous military and humanitarian operations, proving themselves versatile assets. U.S. Army General Norman Schwarzkopf named the USMC Harrier II as one of several important weapons in the Gulf War.
