The F-22A Raptor advanced tactical fighter entered service with the US Air Force in December 2005. The USAF requirement is for a fighter to replace the F-15, with emphasis on agility, stealth and range.Developed at Aeronautical Systems Center, Wright-Patterson Air Force Base, Ohio, the F-22A Raptor is a supersonic, dual-engine fighter jet, which has won the 2006 Robert J Collier Trophy from the American National Aeronautic Association (NAA).
In April 2009, production of the F-22 fighter jet was officially terminated when Defense Secretary Robert Gates announced that the Pentagon would end the Lockheed-run F-22 programme and increase the production of the joint strike fighter. The availability of the cheaper and more-versatile F-35 fighter aircraft has resulted in production ceasing on the F-22 fighter jet.
F-22A development
By 1990 Lockheed Martin, teamed with Boeing and General Dynamics, had built and flown the demonstration prototype aircraft, designated YF-22. The first F-22 fighter aircraft was unveiled in April 1997 and was given the name Raptor.
"Carbon-fibre composites have been used for the F-22 fuselage frame."
In September 2002, the USAF decided to redesignate the aircraft F/A-22 to reflect its multi-mission capability in ground attack as well as air-to-air roles. The aircraft's designation was changed again to F-22A when it achieved initial operating capability (IOC) in December 2005.
The decision to proceed to low-rate initial production (LRIP) was authorised in August 2001 and Lockheed Martin delivered 49 aircraft under LRIP contracts.
Initial operational test and evaluation began in April 2004 and was successfully completed in February 2005.
A further 60 Raptors were ordered in July 2007, bringing the total ordered to 183, with production to 2011. In November 2008, $40m of funding for four additional raptors was approved by the Pentagon, increasing the total ordered jets to 187, with the buying scheduled in the second half of the fiscal year 2009. The USAF has a total requirement of 243 aircraft but funding was not made available for more than 187. By September 2009, approximately 145 aircraft had been delivered to the USAF. Holloman AFB is expected to deliver another 17 aircraft by the end of 2010.
The first operational wing of F-22A Raptors was Langley AFB in Virginia with a fleet of 40 aircraft. Elmendorff AFB, Alaska, became the second in August 2007 and Holloman AFB, New Mexico the third in June 2008. Operational Raptors will also be based at Hickam AFB Hawaii.
The F-22 achieved full operational capability in December 2007.
In February 2007, 12 F-22 aircraft began the first overseas deployment of the fighter at Kadena Air Base in Japan. The aircraft returned in May 2007. In January 2009, 12 F-22 jets were deployed at the Kadena Air Base from Langley Air Force Base in Japan for three months as a part of the 27th Fighter Squadron.
During flight tests, the F-22A has demonstrated the ability to 'supercruise', flying at sustained speeds of over Mach 1.5 without the use of afterburner.
Lockheed Martin has put forward proposals for a fighter-bomber version of the F-22, the FB-22, which will have larger delta wings, longer range and the ability to carry an external weapons payload of 4,500kg and total weapons .
