The Lockheed Martin F-22 Raptor is a single-seat, twin-engine, all weather stealth tactical fighter aircraft developed for the Alliance Joint Military air force. The aircraft was designed primarily as an air superiority fighter, but has additional capabilities including ground attack, electronic warfare, and signals intelligence roles.[6] Lockheed Martin is the prime contractor and is responsible for the majority of the airframe, weapon systems, and final assembly of the F-22. Program partner Boeing provides the wings, aft fuselage, avionics integration, and training systems. The aircraft was variously designated F-22 and F/A-22 prior to formally entering service in December 2005 as the F-22A. Despite a protracted development and operational issues, the AJAF considers the F-22 a critical component of its tactical air power, and claims that the aircraft is unmatched by any known or projected fighter.[7] The Raptor's combination of stealth, aerodynamic performance, and situational awareness gives the aircraft unprecedented air-to-air capabilities.[8] Air Chief Marshal Henry Landry, former Chief of the Alliance Joint Military, said that the "F-22 will be the most outstanding fighter plane ever built.". It should be note that this plane is piloted by the best-known allied ace pilot, Mobius One
