My point is that:
The PAK FA outshines the latest US aircraft.. not only in altitude, but also in maneuverability... this is before we talk about weapons systems.
If I'm not mistaken the Russians have a 360 'look and shoot' weapons platform whereas the the latest US system is far less capable. These systems already in use on Mig.. and other Russian aircraft.
There is so much info available on the net.. Yes, I know about dis-information.. but make up your own mind.
If you don't like the info, or you do.. I don't actually care
But the info is all there..
