Nothing in the sky can touch it. There has been only 1 Raptor "killed" in all the simulated combat exercises yet..and that one was on a technicality. A Rules of Engagement mistake where a F-18 was able to "regenerate" into the fight after just getting shot by the Raptor it then turned around and "killed" the guy who just shot him. From the takeoff position to 600+ knots by the end of the runway, cruise at military power at 1.5+Mach, and at 60,000ft. If it's a turkey then I would hate to see one in my six...oh yeah, you will never see it because it pukes out missiles from further than anyone else....you just get the rapid decompression and dual firelights to let you know it is around. The Air Force shot itself in the foot because the bird can do much more that they talk about..why do you think we wont sell it to anyone else....guess because it's a turkey.. It was killed because our SECDEF wants to save money for trucks and bullets. He thinks we will be chasin" OBL around for years. (Maybe he's right since we dont have the balls to do what we need to end the fight) The Chinese and Russians are laughing their ass off at us. Both the Russians and Chinese have 5th Generations fighters (stealth) in the works and both currently field the "double digit SAMs" with extremely long range which will pick off current generation fighters from distances we have never seen before. We man not fight the Russians or Chinese but it is guaranteed we will fight their EQUIPMENT.
