Because the j-36 and j-XDS will not be as capable as its potential without ws-15 engines or better. Engines are the foundation for everything, more important than 6 gen airframes imo. Thats why we are so upset that the ws-15, much less the rumored next gen vce is being delayed, again

The WS-15 isn’t “delayed”. It’s in production. Insofar as there is an issue right now it’s a supply chain problem.

So we have some earlier J-20A/S prototypes with WS-15 (like No.2052, 2055, 203X), and later ones with WS-10CXX? :oops:

They replaced engines in earlier prototypes from WS-15 to WS-10CXX, or just put WS-10CXX in newly-built prototypes?

How many prototypes have we seen so far, including A & S? What engines are they equipped respectively?

We don't definitively know.

I understand some people have tried to confidently confirm which prototypes have which engines, but from what I have seen in terms of image quality, for J-20A the first prototype 2051 should be a fairly confident WS-10, 2052 is definitely WS-15, but the other J-20A prototypes are unclear.

For J-20S, I am not sure if any of the airframes can be confidently surmised as using WS-15.


And I advise everyone to abide to the rule that "if imagery is less than absolutely definitive, then it is prudent to assume an aircraft/airframe is using the less advanced powerplant option".

That seems weird, WS-15 should be ready since 2023. If true, then we might be far overestimating China's aeroengine maturity. From specs wise 1850K TIT do not seem that advanced (4th gen engines like M88, EJ-200 and later F-110 variants is pushing 1800K. F-119 which 40 year old technology by now has a TIT of 1950K) especially compared to F-135's 2260K TIT and yet China is still having issue getting it into service after over 30 years of development. Personally, I think this is terrible news if confirmed and cast doubt on the future of Chinese military aviation especially with next generation VCE and to an extent the progress on WS-19(Which is meant to use the same technology from WS-15).

PS: God forbid the VTOL project which might also be affected because WS-10 just ain't gonna cut it

Is '1850k' from reliable source?

1850k TIT is from Wikipedia.. and when you click on the link they put as the source from some random Chinese securities magazine back in 2016-17. they itself took data from old Chinese research papers.

this Wikipedia data is at least one decade old i mean they don't have access to any latest information neither AECC disclose any information so they don't have choice but to post anything available. and overall specification is too from 2016 research paper published by Shandong university..

apart from T/W ratio, rest all specifications are missing..
