Initially referred to as the Advanced Tactical Fighter (ATF), the F-22 was designed to meet a USAF requirement for 750 new fighters to replace the F-15 Eagle. Work began in the early 1980s, and competition selection resulted in orders for flying demonstration prototypes of the YF-22 and the Northrop YF-23. The first of two prototypes was flown on 29th September 1990, and extensive testing and evaluation took place during that decade. In 1993 an air-to-ground attack role using precision-guided munitions was added to the original air superiority role, and the designation has been changed to F/A-22 to reflect this. The F-22 is designed to supercruise at up to Mach 1.5 without use of the afterburner, and its unusual layout is designed for agility as well as to incorporate stealth characteristics.
