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. A planned two-seat trainer version, the F-22B was cancelled, but production deliveries are now taking place, with service introduction planned for 2005. Author Jay Miller has followed the program closely to produce an extensively researched and well-illustrated review of this topical new fighter in the well-established and acclaimed Aerofax style and depth.
