you are wrong and i mean no disrespect.
T-50 has several features common with YF-23 rather with Su-27, T-50 flew 20 years after YF-22 and YF-23, you can see the advances simply in aerodynamics, the LEVCON is one, and that is a visible one.
I will not tell you which one is better, since that is a futile work, i will simply say the T-50 has different philosophy, it is designed to track stealth aircraft by means of 5 radars and an IRST system; escape enemy missiles by means of super cruise, and a variable geometry intake that will allow speeds of Mach 2.5 at max speeds and 1.8-19 Mach supercruise.
It is designed to be as stealthy as F-22 by means of planform alignment, composites and a smart skin.
In few words it was designed to be faster, and more maneuverable with a blend of Passive and active radars to detect its rivals at theoretically longer ranges, if it really does or does not well History will tell, but the philosophy of the T-50 reflects two main trends, stealth aircraft can be detected and speed is life and if you can not out run it you have to dodge it
Heh! Heh! ,well I'm may not live that long and I'm not that patient anymore, as I said, a very nice airplane with lots of "doo-dads", the fact that its 20 years behind the Raptor means it has a lot of ground to make up. The Raptor is still getting smarter and gaining capability, in real world speed, no doubt in my mind the Raptor is still top dog, maybe PAK-FA will supercruise??? Maybe it will be "pretty stealthy", but they are putting a lot of money on "active cancellation"???
"you are wrong"??? but you won't tell me which one is better??? now one or both of those statements cannot be correct??? can they??? hummh???,
yes, I do have the question marks copyrighted???? well maybe not????
