; operational experience had highlighted demand for a more capable aircraft. The British government had only a minor requirement, for up to 60 Harriers at most and competing pressures on the defence budget left little room for frivolous expenditure such as the Advanced Harrier. A lack of government backing for developing the necessary engine of the new aircraft, the ''Pegasus 15'', led Hawker to withdraw from this project in 1975.Jenkins 1998, pp. 69–70. Due to US interest, work proceeded on the development of a less ambitious successor, a Harrier fitted with a larger wing and making use of composite materials in its construction. Two prototypes were built from existing aircraft and flew in 1978. The US government was content to continue if a major foreign buyer was found and Britain had a plan to improve the Harrier with a new, larger metal wing. In 1980, the UK considered if the American program would meet their requirements – their opinion was that it required modification, thus the MDD wing design was altered to incorporate the British-designed leading-edge root extensions.Wilson 2000, p. 29. In 1982, the UK opted to become fully involved in the joint US–UK programme.Jefford et al. 2006, p. 81. The US and UK agreement to proceed included a British contribution of US$280 million to cover development costs to meet their own requirements and to purchase at least 60 aircraft. The UK agreement included the involvement of British Aerospace (BAe) as a major subcontractor, manufacturing sections such as the rear fuselage for all customers of the AV-8B. The Harrier II was an Anglicised version of the AV-8B, British Aerospace producing the aircraft as the prime contractor, with McDonnell Douglas serving as a sub-contractor; final assembly work was performed at

The GR5 had many differences from the USMC AV-8B Harriers, such as avionics fit, armaments and equipment; the wing of the GR5 featured a stainless steel leading edge, giving it different flex characteristics from the AV-8B. In December 1989, the first RAF squadron to be equipped with the Harrier II was declared operational.Nordeen 2006, p. 68.


Description and role

The Harrier II is an extensively modified version of the first generation Harrier GR1/GR3 series. The original aluminium alloy

was replaced by one made extensively of composites, providing significant weight reduction and increased payload or range. A new one-piece wing provides around 14 per cent more area and increased thickness. The wing and leading-edge root extensions allows for a 6,700-pound (3,035 kg) payload increase over a 1,000 ft (300 m) takeoff compared with the first generation Harriers.Wilson 2000, pp. 26–27.Walker 1986, pp. 24–25. The RAF's Harrier IIs feature an additional missile pylon in front of each wing landing gear, as well as strengthened

s on the wings in order to meet higher bird strike requirements.Jenkins 1998, pp. 88–89. Among the major differences with the American cousin, was the new ZEUS ECM system, also proposed for the USMC AV-8 (which retained, after an evaluation, the original ALQ-164). ZEUS was one of the main systems in the British design, being a modern and costly apparatus, with an estimated cost of $1.7 million per set. The Harrier II's cockpit has day and night operability and is equipped with

Further developments

Even prior to the Harrier GR5 entering service, it was clear that alterations were required for the aircraft to be more capable in the

, the GR7s were upgraded with encrypted communications equipment.Jefford et al. 2006, p. 96. A further major upgrade programme from the GR7 standard was conducted; the Harrier GR9. The GR9 was developed via the Joint Update and Maintenance Programme (JUMP), which significantly upgraded the Harrier fleet's avionics, communications systems, and weapons capabilities during scheduled periods of maintenance in an incremental manner. The upgrade also replaced the composite rear fuselage of the GR7 with one made of metal which was less vulnerable to damage from engine vibrations. The first of the incremental improvements started with software upgrades to the communications, ground proximity warning and navigation systems, followed by the integration of the AGM-65 Maverick air-to-ground missile. Capability C added the RAF's Rangeless Airborne Instrumentation Debriefing System (RAIDS), Raytheon's Successor Identification Friend or Foe (SIFF) system and the Paveway guided bombs. The Digital Joint Reconnaissance Pod (DJRP) was added as part of Capability D. In February 2007, handling trials of the MBDA Brimstone (missile) began, however the Brimstone would remain uncleared for deployment on the GR9 by the type's early retirement. The

The fuselage components were designed and built as part of a three-year £20 million programme. In July 2008, Qinetiq was awarded a contract to perform upgrades and maintain the Harrier II fleet until 2018, which was the predicted out of service date for the type.

, would operate from the Navy's two new s. The decision to retire the Harrier was controversial, with some senior officers calling for the Panavia Tornado to be retired as an alternative; the decision having left Britain without any fixed-wing aircraft capable of flying from the navy's aircraft carriers. On 24 November 2010, the Harrier made its last ever flight from a carrier, incidentally also the last flight from the carrier prior to retirement. The fleet's last operational flights occurred on 15 December 2010 with fly pasts over numerous military bases. In November 2011, the Ministry of Defence sold 72 Harrier IIs, along with spare parts, to the

According to a report by '' Air Forces Monthly'', some of the 72 Harrier IIs were to fly again, as the USMC planned to equip two squadrons with GR.9/9A models due to the well-maintained condition of the airframes when inspected at RAF Cottesmore, where the aircraft were stored and maintained by a skeleton crew of technicians following their retirement. This was contradicted by the US Naval Air Systems Command (NAVAIR) in June 2012, who stated that the USMC never planned to operate ex-RAF Harriers.


Variants

;GR.5 :The GR5 was the RAF's first model of the second-generation Harrier. The GR5 considerably differed from the USMC AV-8B in terms of avionics, armaments and countermeasures. Forty one GR5s were built. ;GR.5A :The GR5A was a minor variant, incorporating design changes in anticipation of the GR7 upgrade. Twenty-one GR5As were built. ;GR.7 :The GR7 is an upgraded model of the GR5. The first GR7 conducted its maiden flight in May 1990, and made its first operational deployment in August 1995 over the former

Unlike their American counterparts, the T10s are fully combat-capable. ;T.12 :Update of the trainers to accompany the GR9. Nine T10 aircraft received the JUMP updates under the designation T12, however these would retain the less powerful Pegasus 105 engine. ;T.12A :Equivalent to the T.12, however differs by being equipped with the newer and more powerful Mk 107 Pegasus engine of the GR7A/9A.
