The F-22 will replace the F-15 as America's front-line, air superiority fighter, and is designed to counter lethal threats posed by advanced surface-to-air missile systems and next generation fighters equipped with launch-and-leave missiles. It is widely regarded as the most advanced fighter in the world, combining a revolutionary leap in technology and capability with reduced support requirements and maintenance costs. The F-22's combination of stealth, integrated avionics, maneuverability and supercruise will give Raptor pilots a first-look, first-shot, first-kill capability against the aircraft of any potential enemy. Boeing supplies the F-22's wings, aft fuselage, radar, mission software, avionics integration and testing, and training and life-support systems.
