I think the fact that we thought for the longest time the J-XX would be designated J-13 or J-14 and instead we got J-20 should tell us just how mercurial these interim rumor mill designations are.

I think it certainly demonstrated how wrong we were about guessing designations back in the 2000s.... but now we have their 4th gen pattern to go off and their initial 5th gen designation as well.

Certainly I think there's enough reason for us to be doubtful if they'd be willing to use a "30s" designation for a 5th generation fighter rather than a 6th generation fighter, or a sudden leap from J-20 to J-35.

Indeed, as such J-21 for a PLAAF variant would make sense, however the no. 35 is always explained with two versions: First to mock LM and the F-35 and second, since it combines the stealth characteristics of the J-20 in a J-15 successor; as such J-20 + J-15 = J-35.

But my point is: Who is @柳絮纷飞竟不是雪 and how reliable/credible is he/she?
@Deino also match the engine designation to WS21 (former WS 13E)

Yes, but AFAIK the WS-21 is a small turbofan for UAVs and since the J-20/WS-15 has alos no connection by using the same number I don't think, the J-21/31/35 or whatever needs to have the same number for the engines.

There are actually two possibilities: 1. J-21, the AF version of FC-31; 2. JH-21, XAC’s new stealth fighter bomber. Each has its own chance.


Really? There are still rumours concerning the JH-XX?

I think there’s a petty high likelihood that we’ll end up seeing some kind of JH-XX just because it addresses a pretty significant capability gap for the PLA, and they’re no longer resource or capability constrained to pursue such a platform.

Well, rumor never said the JH-XX program is dead.

I know, but equally we - or at least I - haven't heard any more rumours since months? Or did I miss something?

I think SAC are just obsessed with rule of cool in their fighter numbering.

It was all sequential and sensible up to J11, but then they jumped to J15 and J16 (which I could kinda accept if they assigned unofficial J-numbers to the imported flankers, with J12-MKK, J13-MK2 and J14-Su35).

J20 makes sense as a clear generational leap (similar to J10 and J11 move up from the J7 and J8, although those were also sequential due to the experimental J9), and then SAC went completely nuts with J31/35.

It would good if the PLAAF imposed some sanity and make the SAC 5th gen J21 in keeping with traditional and bloody common sense!
