Design and development

Development of a successor to the first Harrier began as a cooperative effort between McDonnell Douglas (U. McDonnell Douglas was a major American Aerospace manufacturer and Defense contractor, producing a number of famous commercial and military aircraft S. ) and Hawker Siddeley (UK). Hawker Siddeley was a group of British manufacturing companies renowned for their aircraft production. Cost overruns eventually led Hawker to withdraw from the project, but work continued due to U. Cost overrun is defined as excess of actual Cost over Budget. S. interest in the aircraft. Britain re-entered development in the late 1970s, producing their own version of the Harrier II based on the U. S. design. For UK variants, BAE Systems is the prime contractor and Boeing a sub-contractor.

The Harrier II is an extensively modified version of the first generation Hawker Siddeley Harrier GR1/GR3 series which first flew in December 1967. WikipediaWikiProject Aircraft.

In RAF service, Harriers are used in the ground attack and reconnaissance roles. Ground-attack aircraft are military aircraft designed to attack targets on the ground and are often deployed as Close air support for and in proximity to their own ground forces Reconnaissance (also scouting) is a military and medical term denoting exploration conducted to gain information Unlike the Harrier AV8B+ upgrade, the RAF have chosen not to integrate a radar into its aircraft, although the aircraft retains an Inertial Navigation System. Radar is a system that uses electromagnetic waves to identify the range altitude direction or speed of both moving and fixed objects such as Aircraft, ships An Inertial Navigation System (INS is a Navigation aid that uses a Computer and motion sensors to continuously track the position orientation and Velocity The primary air-to-air missile (AAM) of the Harrier is the infrared-homing AIM-9 Sidewinder (the combination of Harrier and Sidewinder proved effective against Argentinian Mirages in the Falklands conflict), but it does not carry the medium range AIM-120 AMRAAM missile. Infrared homing refers to a passive missile guidance system which uses the emission from a target of Electromagnetic radiation in the Infrared The AIM-9 Sidewinder is a heat-seeking, short-range Air-to-air missile carried by Fighter aircraft and recently certain gunship helicopters For a topic outline on this subject see List of basic Argentina topics.

The Harrier GR7 formed the spearhead of the RAF's contribution to Operation Allied Force, the NATO mission in Kosovo. The NATO bombing of Yugoslavia (code-named Operation Allied Force) was NATO 's military operation against the Federal Republic of Yugoslavia that The North Atlantic Treaty During this campaign the RAF identified significant shortcomings in its current arsenal. As a result the service ordered the AGM-65 Maverick stand-off missile and the Enhanced Paveway which incorporates GPS guidance which would negate the effects of smoke and bad weather.

The Iraq War, also known as the Second Gulf War, the Occupation of Iraq, or the War in Iraq, is an ongoing Military campaign RAF GR7s participated in strike and close air support missions throughout the conflict. The first operational deployment of the Harrier GR9 was in January 2007 at Kandahar in Afghanistan as part of the NATO International Security Assistance Force (ISAF). International Security Assistance Force (10 ( ISAF) is a NATO -led security and development mission in Afghanistan established by the United Nations Harrier GR7s were deployed to Afghanistan in 2006 as part of the expanded ISAF mission in the south of Afghanistan. Reflecting the increased pace of operations, RAF Harrier GR7As saw a large increase in munitions used, mainly CRV7 rockets and laser guided bombs, used supporting ground forces since July 2006. Between July and September, the theatre total for munitions deployed by British Harriers on planned operations and Close Air Support to ground forces rose from 179 to 539. [2]

Future

With the withdrawal of the Royal Navy's Sea Harrier in 2006, the RAF's Harrier fleet is tasked with the missions that it used to share with those aircraft. The Royal Navy of the United Kingdom is the oldest of the British armed services (and is therefore known as the Senior Service) In 2006, the GR9 also entered service with the Fleet Air Arm when the first former Sea Harrier squadron reformed. The Fleet Air Arm is the branch of the Royal Navy responsible for the operation of the aircraft on board their ships The GR9 is expected to stay in service at least until 2015, when the first F-35s are due. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout At this point, the JSF force should be gaining an initial operational capability (IOC). The Joint Strike Fighter (JSF became synonymous with the later F-35 Lightning II, however until 2001 the term was applied to the competition between the Boeing X-32

Variants

Since 1969, 824 Harrier variants have been delivered.


GR5

The GR5 was the RAF's first second-generation Harrier, with development beginning in 1976. Two AV-8As were modified to Harrier II standard in 1979 and operated as development aircraft. The first BAE built development GR5 flew for the first time on April 30, 1985 and the aircraft entered service in July 1987. Events 313 - Roman emperor Licinius unifies the entire Eastern Roman Empire under his rule This is a list of Aviation -related events from 1985: Events Ryanair founded initially as a full-service carrier The GR5 differed from the USMC AV-8B in many subtle ways, for example avionics fit, weapons and countermeasures. Forty one GR5s were built.

GR5A

The GR5A was a minor variant of the Harrier which incorporated changes in the design in anticipation of the GR7 upgrade. Twenty-one GR5As were built.

GR7

The GR7 had its maiden flight in May 1990 and made its first operational deployment in August 1995 over the former Yugoslavia. See also Kingdom of Yugoslavia, Socialist Federal Republic of Yugoslavia, Federal Republic of Yugoslavia Yugoslavia ( Serbo-Croatian While the GR7 deployed on Invincible class aircraft carriers during testing as early as June 1994, the first operational deployments at sea began in 1997.

Rolls-Royce plc ( is a British Aircraft engine maker and the second-largest in the world behind GE Aviation. WikipediaWikiProject Aircraft. Please see WikipediaWikiProject Aircraft/page content for recommended layout When upgraded to GR9 standard the uprated engine variants will retain the A designation, becoming GR9As. Forty GR7s are due to receive this upgrade. The Mk 107 engine provides around 3,000 lbf (13 kN) extra thrust than the Mk 105's 21,750 lbf (98 kN) thrust, increasing aircraft performance during "hot and high" and carrier-borne operations. Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws.

GR9

The Harrier GR9 is an avionics and weapons upgrade of the standard GR7. This upgrade, known as the Integrated Weapons Programme (IWP), allows the carriage of the latest smart weapons, new inertial navigation and Global Positioning systems (INS/GPS). An Inertial Navigation System (INS is a Navigation aid that uses a Computer and motion sensors to continuously track the position orientation and Velocity Basic concept of GPS operation A GPS receiver calculates its position by carefully timing the signals sent by the constellation of GPS Satellites high above the Earth The new weapons being integrated are the Brimstone, Maverick, Paveway III LGB and Paveway IV PGB missiles. Brimstone is an advanced air-launched Anti-tank guided missile developed by MBDA. The AGM-65 Maverick is an air-to-ground tactical missile (AGM designed for close air support Combat history The GBU-27 was used in Operation Desert Storm. The Raytheon Paveway IV is a new-generation dual mode GPS / INS and Laser guided bomb for use by Military aircraft.

The aircraft will also be fitted with Sniper targeting pods. The Lockheed Martin Sniper XR Advanced Targeting Pod (Sniper ATP provides positive target identification autonomous tracking coordinate generation and precise weapons guidance In July 2007, BAE Systems completed the final of seven Harrier GR9 replacement rear fuselages for the UK MoD. The fuselage components were designed and built as part of a three year £20 million programme. [3]

GR9A

The Harrier GR9A is an avionics and weapons upgrade of the uprated engined GR7As.

T10

The Harrier T10 is the original two seat training variant of the second-generation RAF Harrier. A trainer is an Aircraft used to develop piloting navigational or war-fighting skills in flight crew The RAF considered upgrading the first-generation Harrier trainer, the T4, to Harrier II standard. However due to the age of the airframes and the level of modification required, the service decided to order new build Harrier II trainers. The RAF used the USMC trainer, the TAV-8B, as the basis for the design. Unlike their American counterparts the T10s are fully combat capable. Thirteen aircraft were built.

T12

With the upgrades bringing the GR7s to GR9 standard, the RAF requires representative trainers. These aircraft will be the T12, the T10s with the IWP upgrade.
