>the whole concept of "stealth" aircraft may be limited in the future thanks to ever increasing computation power and clever usage of existing radio waves I have to disagree. Manufacturers will continue to build stealthy planes and drones, simply because it makes it harder to detect them. Yes, you may be able to detect a stealthy plane at, say, 100km, but using the same techniques you would be able to track a non-stealthy plane at 200km. Stealth isn't an end-all be-all tool that makes vehicles completely invincible, as the Bosnian shootdown of the F-117 showed, but it does make it harder, and I don't know of any technologies that could render it completely useless.
