4. F-22 Raptor

It is supposed to be the jet for the 21st century—a combination of super-cruise, supermanueverability, sensor fusion and stealth all in one package. Through a combination of delays, cost-overruns, wide dispersement of manufacturers and a changing combat landscape, it never really took off….both literally and metaphorically. While many stood by its creation for years, it finally fell victim to its own hype. This episode of AIR WARRIORS profiles the F-22 Raptor, the history of stealth fighters and where fighter jets are heading next.
