I'm not convinced. Stealth has been around for a number of years. We had the F-117 Nighthawk, which flew in Bosnia. That had stealth capabilities. The B-2 bomber was a stealth plane that was built in the 1980s. It's been around for many years.
As I mentioned, I think if the stealth requirement was absolutely necessary for the United States in Libya, they would have deployed those F-22s right away, but they didn't do it. Nobody really knows why. It's an unanswered question, why the F-22s weren't sent to Libya. I just don't think that is the be-all and end-all. You also would have to look at the other capabilities of the aircraft: for instance, its speed--it's slow. It's not as fast as even a 30-year-old F-18.
So what is the main capability that's going to keep a pilot alive? Is it the radar-absorbing paint on the outside, or the fact that it can fly at Mach 1.8 instead of Mach 1.6, or the range? I think you have to consider other factors.
