Well lets not get ahead of ourselves shall we, the J-20 will have 5 years extra to advance it's capabilities compared to the T-50 and 15 to the F-22.
Whoa -- five years? where did you pull that number from? :O
As far as we know, RCS wise, the J-20 is not all aspect and as Martian has said, gains significantly as the angles change. The T-50 on the other hand, is all aspect, and is estimated to be around -20 dbsm. That means that passive SAM waiting for J-20s to fly by can get a huge lock once the J-20's fly by, something that won't happen with F-22s or T-50s.
Actually it's far more all aspect than the T-50 is, and I'm not talking about the engine nozzle. The whole rear/underside has the engine "pods" unshaped and exposed like the Su-27.
J-20 on the otherhand have them fully embedded into the structure, with the rear/underside section of the fuselage consistent with the forward/underside fuselage.
I'm out of my depth here, but unless you offer a better argument on why it isn't all aspect (aside from engines, and in a stealth shaping sense) I don't think the statement's valid.
Another thing, China does not have fully capable indigenous engines that can put the J-20 airframe to it's maximum capabilities, so they'll have to purchase them from Russia,which is terrible for the PRC as Russia can downgrade anything they export or not export those engines at all.
Assuming WS-15 isn't ready in time.
Sensor wise, the J-20 does not even have it's AESA radar yet, that is still in development. Without a fully functional AESA, whenever the J-20 opens it's search lights it is lit up like a candle in a darkroom, something that is easy pickings for enemy air defenses. So in that regards, the T-50 is still more advance than the J-20.
By not have, do you mean it is not installed or it's AESA is not completed or it isn't in the final stages of development or what?
Member 70092, who has shown to be fairly reliable in the past has made a few posts saying J-20's radar is nearly finished if not already finished.
The fact is that radar wise J-20 will have an AESA and will be one of the earlier parts of the system that will be ready. Engines may be one of the later ones.
Stealth wise, Sukhoi has stated that they're sacrificing RCS for Maneuverability, the J-20 on the other hand, does the same thing, except it sacrifices less RCS and has less maneuverability.
Lol interesting conclusion.
So basically you're saying it's more stealthy than the T-50 but more manouverable than the F-22
I can agree that the J-20 air frame is fully functional, but like the PAK-FA, the J-20 is not going to get produced, at least not yet, simply because all the parts and pieces are non-existent.
Yes because they conceived a fifth generation fighter two decades ago without thinking ahead of all the engines, avionics, materials which will be necessary on such a fighter, thus they didn't start development of such aspects and therefore must be very far away from completing them at present.
Nah.
And please, you have yet to provide any sources so before you call me out provide a link or two.
Sources in terms of secret PLA projects consist of what we can skive from the chinese boards, what some more informed members post on english boards, and a good dose of speculation.
Just use common sense.
I should also mention that I love how you guys interpret any criticism of the J-20 as J-20 bashing, that's simply absurd and a logical fallacy.
Not quite -- I can criticize J-20:
It's LERX's are rounded, which may compromise stealth a little from the forward and side aspect, it has ventral tails which will adversely effect stealth, the engine nozzles aren't as stealthy as they could be, the landing gear isn't as robust as the PAK FAs' is which would permit for easier modification to a carrier variant, the width of its wings seem a little small compared to the overall length of the aircraft...
But the majority of your criticisms are... incorrect.
