TheLockheed Martin/Boeing F-22 Raptoris a single-seat,twin-enginefifth-generationsupermaneuverablefighter aircraftthat usesstealth technology. It was designed primarily as anair superiority fighter, but has additional capabilities that includeground attack,electronic warfare, andsignals intelligenceroles.[5]Lockheed Martin Aeronauticsis the prime contractor and is responsible for the majority of the airframe, weapon systems and final assembly of the F-22. Program partnerBoeing Defense, Space & Securityprovides the wings, aft fuselage, avionics integration, and training systems.

The aircraft was variously designatedF-22andF/A-22during the years prior to formally entering USAF service in December 2005 as theF-22A. Despite a protracted and costly development period, theUnited States Air Forceconsiders the F-22 a critical component of U.S. tactical air power, and claims that the aircraft is unmatched by any known or projected fighter.[6]Lockheed Martin claims that the Raptor's combination of stealth, speed, agility, precision and situational awareness, combined with air-to-air and air-to-ground combat capabilities, makes it the best overall fighter in the world today.[7]Air Chief MarshalAngus Houston, former Chief of theAustralian Defence Force, said in 2004 that the "F-22 will be the most outstanding fighter plane ever built."[8]

The high cost of the aircraft, a lack of clear air-to-air combat missions because of delays in the Russian and Chinese fifth-generation fighter programs, a U.S. ban on Raptor exports, and the ongoing development of the planned cheaper and more versatileF-35resulted in calls to end F-22 production.[N 1]In April 2009, theU.S. Department of Defenseproposed to cease placing new orders, subject to Congressional approval, for a final procurement tally of 187 operational aircraft.[10]TheNational Defense Authorization Act for Fiscal Year 2010lacked funding for further F-22 production. The final F-22 rolled off the assembly line on 13 December 2011 during a ceremony atDobbins Air Reserve Base.[11]

Starting in 2010, the F-22 was plagued by problems with its pilot oxygen systems which contributed to one crash and death of a pilot. In 2011 the fleet was grounded for four months before resuming flight operations, but reports of oxygen systems issues have continued.[12]In July 2012, the Air Force announced that the hypoxia-like symptoms experienced were caused by a faulty valve in the pilots' pressure vest; the valve was replaced and changes to the filtration system were also made.
