During flight tests, the F-22A has demonstrated the ability to 'supercruise', flying at sustained speeds of over Mach 1.5 without the use of afterburner.
Lockheed Martin has put forward proposals for a fighter-bomber version of the F-22, the FB-22, which will have larger delta wings, longer range and the ability to carry an external weapons payload of 4,500kg and total weapons.
