Then what is F-22 speed then? LM says mach 2. http://www.lockheedmartin.com/us/products/f22/f-22-specifications.html http://youtu.be/bCgLdFVppd4?t=10m28s The T-50 is purposely designed to outperform the F-22.

Aircraft with fixed intakes like F-22 and F-16 are limit to Mach 2. Aircraft with variable intakes can go faster, like the Su-27 at Mach 2.35, F-15 at Mach 2.5, and so on. The T-50's variable intakes and high sweep angles doesn't make sense for Mach 2 limit.

Fine, if it's max speed is only Mach 2, then why the high sweep angles and variable intakes? Not only that, the F-22 max speed is Mach 2, so how is the T-50's max speed less?

http://www.paralay.com/pakfa/pakfa.html Seems like a good source for T-50 info. The given altitude reflects the goal of breaking an area of coverage of air defense Patriot PAC3 MIM-104F Flight altitude 79,500 feet (24,200 m).

From radioscanners who are pretty legit.

Wait, so you're implying that the T-50 max speed is lower than the F-22? That's hard to believe. :ermm:
