The Harrier Jump Jet, often referred to as just "Harrier" or "the Jump Jet", is a British designed military jet aircraft capable of Vertical/Short Takeoff and Landing (V/STOL) via thrust vectoring. The Harrier family is the only truly successful design of this type from the many that arose in the 1960s.
There are four main versions of the Harrier family: Hawker Siddeley Harrier, British Aerospace Sea Harrier, Boeing/BAE Systems AV-8B Harrier II, and BAE Systems/Boeing Harrier II. The Hawker Siddeley Harrier is the first generation version and is also known as the AV-8A Harrier. The Sea Harrier is a Maritime strike/air defence fighter. The AV-8B is the second generation Harrier and the BAE Harrier II is the British variant.
The Hawker Siddeley Harrier GR.1/GR.3 and the AV-8A Harrier were the first generation of the Harrier series, the first operational close-support and reconnaissance attack aircraft with Vertical/Short Takeoff and Landing (V/STOL) capabilities. These were developed directly from the Hawker P.1127 prototype and the Kestrel evaluation aircraft.
The Harrier was extensively redeveloped by McDonnell Douglas and British Aerospace, leading to the AV-8B Harrier II and Harrier GR5/GR7/GR9, respectively. Both were built by companies that are now parts ofBoeing and BAE Systems.
The British Aerospace Sea Harrier is a naval V/STOL jet fighter, reconnaissance and attack aircraft, a development of the Hawker Siddeley Harrier. The first version entered service with the Royal Navy's Fleet Air Arm in April 1980 as the Sea Harrier FRS.1, and was informally known as the Shar. The upgraded Sea Harrier FA2 entered service in 1993. It was withdrawn from Royal Navy service in March 2006. The Sea Harrier FRS Mk.51 is in active service with the Indian Navy, which operates the jet from its aircraft carrier INS Viraat.
The Boeing/BAE Systems AV-8B Harrier II is a family of second-generation V/STOL jet multi-role aircraft of the late 20th century. Developed from the earlier Hawker Siddeley Harrier, it is primarily used for light attack or multi-role tasks, typically operated from small aircraft carriers. Versions are used by several NATO countries, including Spain, Italy, and the United States. The BAE Systems/Boeing Harrier II is a modified version of the AV-8B Harrier II. The Harrier II is used by the Royal Air Force (RAF) and, since 2006, the Royal Navy. Both are primarily used for light attack or multi-role tasks, and are often operated from small aircraft carriers.
Between 1969 and 2003, 824 Harrier variants were delivered. While manufacture of new Harriers concluded in 1997, the last remanufactured aircraft (Harrier II Plus configuration) was delivered in December 2003 which ended the Harrier production line.
