The McDonnell Douglas AV-8B Harrier II is a family of second-generation vertical/short takeoff and landing or "V/STOL" jet multirole aircraft of the late 20th century. British Aerospace rejoined the project in the early 1980s, and it has been managed by Boeing/BAE Systems since the 1990s.

Developed from the earlier Hawker Siddeley Harriers, it is primarily used for light attack or multi-role tasks, typically operated from small aircraft carriers and large amphibious assault ship. Versions are used by several NATO countries, including the United Kingdom, Spain, Italy, and the United States.

The aircraft is known as the AV-8B Harrier II in United States Marine Corps service and the Harrier GR7/GR9 in British service. Though it shares the designation letter-number with the earlier AV-8A/C Harrier, the AV-8B Harrier II was extensively redesigned by McDonnell Douglas. The AV-8A was a previous-generation Hawker Siddeley Harrier GR.1A procured for the US Marine Corps. These models are commonly referred to as the "Harrier Jump Jet".

Development

The Harrier II is notable as an example of US-UK cooperation and of Cold War defense achievements. Of note is the U.S aid funding early development of the Hawker P.1127 under the Mutual Weapons Development Program (MWDP), and the salvaging of what was left of the AV-16 Advanced Harrier Program by McDonnell Douglas, making the second-generation family possible.

McDonnell Douglas had restarted its own program which was nearing production status when British Aerospace (BAe) rejoined the program in the 1980s. They then jointly produced the aircraft. By the 1990s McDonnell Douglas merged with Boeing, and BAe was merged into BAE Systems who went on to manage the family into the early 21st century.

The AV-8B had its direct origins in a joint British-U.S. project (Hawker-Siddeley and McDonnell Douglas) for a much-improved Harrier aircraft, the AV-16. However cost over-runs in engine development on the part of Rolls-Royce and in the aircraft development caused the British to pull out of the program.

Interest remained in the U.S., so a less ambitious, though still expensive project was undertaken by McDonnell on their own catered to U.S. needs. Using knowledge gleaned from AV-16 development, though dropping some items such as further Pegasus development, the development work continued leading to the AV-8B for the U.S. Marine Corps. The aircraft was centered on the Marines' need for a light ground attack aircraft and focused on payload and range, instead of speed. In the early 1980s, the British restarted development of their own second generation Harrier based on the U.S. design which led eventually to the GR.5.

The first two YAV-8B prototypes were converted from existing AV-8A airframes.

Aircraft were built by McDonnell Douglas and British Aerospace (later BAE Systems), the latter at their Kingston & Dunsfold facilities in Surrey, in the UK. The British factories were also home to the Hawker Hunter, and BAe Hawk T1.

Design

The first AV-8B Harrier IIs produced were commonly known as the "Day Attack" variant, and are no longer in service. Most were upgraded to "Night Attack Harrier" or "Harrier II Plus" standards, with the remainder being withdrawn from service.

Fielded in 1991, the Night Attack Harrier incorporated a Navigation Forward Looking Infrared camera (NAVFLIR). The cockpit was also upgraded, including compatibility with night vision goggles. Concurrent with the new version of the aircraft was introduced a more powerful Rolls Royce Pegasus II engine. It was originally intended to be designated AV-8D.cite book |last= Donald |first= David |coauthors = Daniel J.

The Harrier II Plus is very similar to the Night Attack variant, with the addition of an APG-65 radar in an extended nose, making it capable of operating advanced missiles such as the AIM-120 AMRAAM. The radars were removed from early F/A-18 Hornets which had been upgraded with the related APG-73. The Harrier II Plus is in service with the USMC, Spanish Navy, and Italian Navy.

The AV-8B cockpit was also used for the early trialling of DVI using a system developed by Smiths Industries. [Adams, Charlotte. [http://www.fcw.com/print/3_57/news/65657-1.html?type=pf "Voice-recognition technology: Waiting to exhale"] 14 December 1997. Retrieved: 15 July 2008.]

Operational history

The AV-8B Harrier II is used by the military forces of three nations. The United States Marine Corps has operated the AV-8B and TAV-8B since 1985. The Spanish Naval air wing ("Arma Aerea De La Armada") operates the AV-8B and AV-8B+, as well as a leased TAV-8B. The Italian Navy air wing ("Aviazione di Marina Militare") also uses the AV-8B+ and TAV-8B.
