    Are you saying that you’re more knowledgable than him?. I bet if you’re really that smart you wont have the time to waste on Pakistan Defence lmao. I’ve wasted enough time with you, I have way better things to do than arguing the non existence difference of “can” and “able to” lmao.

    J-20 is obviously a newer design. EOTS and DSI are copied straight from F-35. Wing configuration is copied right from MiG 1.44. F-22 is pretty old design.

    You are correct that you wasted my time with me, someone who is far more knowledgeable than you about this subject.

    The Doppler component predate the F-117, and yet since the F-117, there is not one radar system out there that have PROVEN to successfully used the Doppler component against 'stealth'.

    There you have it. Why not have any weather radar managed to detect 'stealth'?

    So yes, your time was truly wasted because you ended up blowing away your own arguments.

    You angered another person again? In fact I have to admit that your knowledge from your past job in the military is informative. However, the way you reply would spark off argument. You could have just replied nicely and nothing goes wrong.

    The spratlys issue and current Trump becoming Democrats style (after his business revival plan failed), there might be J20 vs F22 faceoff after the artificial island expansion is complete. At least a squad of J20 should be stationed there. Since both are stealth, most likely they'll be spotted via satellites and fighters will be sent in to their coordinates. If j20 being scrambled to intercept the intruding F22, how far can their AESA detect each other based on your guess? Under 20, 10 or 5 miles before they could track and lock on to launch active radar missiles? Put aside IR guided missile.

    A small bird flying at supersonic speed or high subsonic speed is really hard to miss.

    I addressed this YRS AGO on this forum. If what you said is true, then 'stealth' would have died out a long time ago.

    Older but still appears to be the best, it set the standard and still does.

    I am not aware of satellite tracking of flying stealth aircraft but they may get an idea of what base is occupied as certain times. It would be hard to guess detection ranges because we know relatively little about f-22's signature and even less about j-20. I would guess that j-20's first generation aesa has less performance than f-22's and that f-22's radar signature is smaller but I don't know by how much. Also f-22 has some IR suppression and I don't know if J-20 does. If these things are remotely true that means f-22 gets first look and first shot all things being equal. Also F-22 has the edge I would guess in close in fighting but J-20 has more range. Until J-20 gets it's ws15s complete and we get some performance specs f-22 can out run j-20 but would need tanker support more.

    I thought all "vs" threads are banned?

    Unless there were some major announcement that I missed, I don't think they are.

    However, in many of those types of "Vs." threads, there ends up unfortunately being moderate to severe amounts of trolling.

    To the point where some people will take one side, not because it's technologically sound, but because it's against or for a specific country or countries Tech.

    And we can all see them for the tools they are, I don't see the problem.

    That point have been dealt with by many different angle.

    Would suggest you go look up what mine and @gambit response are on the issue.

    F22 is indeed superior in RCS and maneuverability. There's rumor that former US stealth engineers were involved in J-20 design apart from the reverse engineered stealth tech from F117 shot down over Serbia. The J20 will need the WS15 engine for complete air superiority. If war really happens, either both unable to track and acquire lock on each other getting into visual range dogfight or one of them able to acquire lock earlier. It all depends on avionics in this situation. Won't know until they really seen actual combat.

    It depends on both stealth and avionics, f-22 most likely has better stealth given what info is available and probably better radar but I don't know about ESM and j-20 has that EOTS. I also doubt the avionics will match f-22/35, this is their first generation stealth and that also includes the stealth of the radar and things that are not so readily seen. I think j-20 will be detected first but j-20 will be more difficult to find than f-22 is used to. F-35s and other sensors will play a big role and helping f-22 find j-20 and teamwork will be more important but f-35 and all the other networked sensors have had this in mind for a while now. J-20 will use its better range and long range weapons to try to sneak in and shoot from as far as possible and try to make it back. I don't think j-20 wants to tangle with f-22/35.
