This is not j-20 but j-10b aesa,,the pic u are showing on topWe are already ahead in radar. Engine is where we want to achieve parity with the USA. Russia is not far off when WS-15 roll around in 2020.
1856 t/r for J-20.
I never said fak-fa is not a potent platform. It certainly very impressive, especially with its super agility design, maneuverability, and missile capability in air-fight. However, lacking low-observable stealth will make it easy target for true 5th generation fighter.
That is why I said this platform is a true 4+++ gen. It's a super Su-35 but it's not F-22 parity, if you get what I mean.
