The AV-8B is a high performance, single-engine, single-seat, Vertical/Short Take-off and Landing (V/STOL) attack aircraft. It was introduced to the Fleet Marine Forces (FMF) in January 1985 after a successful prototype demonstration and Full Scale Development Program. Consistent with the long-standing Marine Corps vision of attaining an all V/STOL amphibious force, the AV-8B replaced both the A-4M and AV-8A/C -- the light attack portion of the Marine Tactical Aircraft (TACAIR) force.

The AV-8B was designed primarily to improve upon the performance and handling qualities of the AV-8A/C. It was a new design, with composite structures, a bigger wing, higher engine thrust and reliability, and state-of-the-art avionics; however, it did retain the fundamental single-engine, vectored exhaust nozzle configuration of its predecessor. Where possible, and within tight budgetary and schedule constraints, the prime contractors were also challenged to improve reliability and maintainability (R&M). At the time R&M was a much stronger design driver in the ongoing F/A-18 development program.

As hoped, the flying qualities, performance and warfighting capabilities of the AV-8B proved to be dramatic improvements over those of the AV-8A/C. Although hampered by some significant susceptibility and vulnerability deficiencies, the AV-8B, with its flexible basing, high sortie generation capability and accurate weapon system acquitted itself admirably under combat conditions in the Persian Gulf. However, by the end of 1991, the cumulative (non-combat) mishap rate was disappointingly high at more than 14 per 100,000 flight hours for its first seven operational years.

By 1998, approximately 50% of the Marine Corp's single-seat AV-8Bs and six two-seat TAV-8B's were configured with the 408A engine. A Department of Defense (DoD) decision to retrofit all of the TAV-8Bs with the 408A not only provides increased thrust - thereby providing a larger margin for safety - but improves maintainability within the FRS. It also provides an opportunity to establish a common engine for the entire Harrier community. However, some of the important planned maintenance and logistics support features of the new engine had yet to be realized. The EMS was initially only partially fielded, with no usable ground stations for retrieval of data available at the squadron level, and neither the RCM nor the modular maintenance programs had been adequately funded.

The fighter version of the aircraft is manned by a single pilot; a two-seat trainer with the full military capability of the single seater is also available. As with so many modern jet fighters, the Harrier is equipped with zero-zero ejection seats; that is, crew escape is possible on the runway at zero altitude and zero speed.

The AV-8 B's wing is made out of one piece, including ribs and skins. It's ailerons, flaps, outrigger pods and fairings, forward part of fuselage, tailwings and rudder, are manufactured mainly from graphite epoxy (carbonfibre) and other composites. The centre and rear fuselage, wing leading-edges (reiforced aiganst bird strikes on RAF aircraft) , wingtips, tailplane leading-edges and tips, and fin, are of an aluminium alloy. Small sections of the bottom, heatshields, and the nose of the Harrier are constructed out of titanium.

AV-8B Harrier II Plus Radar Aircraft

The Radar Aircraft, also known as the Harrier II Plus, was introduced in July 1993 as the newest production AV-8B, achieving Initial Operating Capability in August 1997.

The current Radar/Night Attack Harrier, or Harrier II+, has all the improvements of the Night Attack aircraft plus the AN/APG-65 multi-mode radar. The fusion of night and radar capabilities allows the Harrier to be responsive to the MAGTF's needs for expeditionary, night and adverse weather, offensive air support. The AN/APG-65(V)2 tactical airborne radar system is based on existing specifications for F/A-18 Aircraft; it provides the AV-8B multi-target tracking capability and the ability to perform air-to-air and air-to surface weapons delivery in conditions of marginal visibility, day or night.

In the Radar Aircraft, the AN/APG-65(V)2 Radar System is based on the existing specifications for F/A-18 Aircraft, but tailored for AV-8B missions. Current AV-8B specifications for the radar include a downsized antenna, two modified Shop Replaceable Assemblies (SRA), and commonality with existing items to the maximum extent without compromising performance or mission reliability. The radar modes originally developed in the F/A-18 AN/APG-65(V)2 Radar System were retained, and provide the Radar Aircraft, in conjunction with the Radar Aircraft?s night-attack systems, extended tracking capabilities to perform air-to-air and air-to-surface operations in marginal visibility conditions, day or night. The AN/APG-65(V)2 Radar is a tactical airborne radar system developed by Hughes, Inc.

To remain responsive to fleet needs, older Day Attack AV-8Bs are being remanufactured to the Radar/Night Attack Harrier II+ standard. Plans called for 72 Harriers to undergo remanufacture through FY 2001, reusing major assemblies and components of the Day Attack aircraft in combination with new production structure, systems, and engines. In addition, the Marine Corps was considering remanufacture of an additional 24 aircraft, to be completed by 2003.

The ongoing "remanufacture" program, in which 72 Day Attack aircraft from the existing inventory are being rebuilt to the Radar/ Night Attack standard, extends the service life of these Harrier aircraft into the new century, and greatly improves their warfighting capabilities. Existing Harriers are also being upgraded through the use of commerical off-the-shelf (COTS) technology. The Open Systems-Common Architecture program will replace the existing Harrier mission computer with a COTS system that is affordable and easily upgraded and maintained.

Sea Harrier

The Sea Harrier fighter (FRS.1), which is in service with the British Royal Navy and the Indian Navy, provides air defence for the carrier fleet , particulary against low-flying attack aircraft armed with long-range air-to-surface missiles.
The design of the aircraft is optimised for air-to-air with secundary missions of surveillance, air-to-sea and air-to-ground attack. The Sea Harrier has one of the best air-to-air combat records in recent military history, shooting down 28 Argentine warplanes in the falklands War for no loss. The FRS.1 Sea Harrier is quite similair to the AV-8 B harrier, except for the forward fuselage. The cockpit was raised, room in the forward fuselage has been increased for additional avionics. This gives the Sea harrier much greater all round vision.

The Sea Harrier's nose contains a recon camera and a Ferranti Blue Box multimode radar, which is a development of the Lynx helicopter's Sea Spray radar.

The F/A.2 is the latest version of the Sea Harrier in service with the Royal Navy (45 aircraft). The F/A.2 is an upgraded version of the FRS.1 Sea harrier. It is able to detect and destroy threats before the launch of an attack using long range weapon systems with look-down and shoot-down tactical capability.
