The F-22’s basic challenge was to integrate stealth, supercruise, highly integrated avionics and agility into an aircraft with a longer range than the one it was to replace, the F-15 Eagle. It was also to have twice the reliability of the F-15 and half the support requirements. Although in practice, the F-22’s mission availability has risen over the last few years to being close to that of the F-15, but its support requirement is over 50 percent higher.
America’s F-22 Raptor is one of the world’s most advanced warplanes. But it has several weaknesses. For one, it’s blind in the infrared though several of its potential rivals have infrared-search-and-track sensors, effectively allowing them to scan for enemy warplanes’ heat signatures.
