Joint Strike Fighter (JSF) will be a single-seat, supersonic aircraft incorporating stealth technology due to replace RAF Harrier GR7/GR9s and Royal Navy Sea Harrier F/A2s in the early part of the next decade. Capable of performing multi-role operations from aircraft carrier and land, two consortia, one led by Boeing (with the X-32) and the other by Lockheed Martin (the X-35), are in competition to win orders from not only UK forces, but also the US Air Force, Navy and Marine Corps where it will replace the F-16 Fighting Falcon, AV-8 Harrier and F/A-18 Hornet. Possible total production of the JSF is estimated to be some 5,000 aircraft including export models. Current plans call for some 150 aircraft for the RAF and RN.
