J-35A fighter (PLAAF) + FC-31 thread

[ACuriousPLAFan]

but why naval variant using inferior Engines(WS-21) as compared to land variant(WS-19).. this doesn't make sense to me.

WS-21 itself an advanced machine but inferior to WS-19.

He stated that although the J-35A incorporates many low-end configurations, it used the WS-19 engine during the September 3rd military parade, which is considered a high-end configuration. He also mentioned that the initial batches of the J-35 were equipped with the WS-21 engine, but did not explain the reason for this.

I would suppose that reliability and stability considerations for carrier-based operations play key roles in the current arrangement of having WS-21 powering the J-35 instead of WS-19, given the greater constrains and stricter requirements for carrier-based operations than land-based operations.

Either way, I think the early J-35 units flying with WS-21 is still a rather good thing, rather than having to stick with the old a$$ WS-13.

Should it be understood that the carrier J-35 will get WS-19s too, right? If so perhaps the reason could be that the WS-19 has not been certified in the enhanced corrosion protection version just yet, and/or the reliability is not quite yet to the level required for carrier use (but will do for the land based J-35A).

yeah. same thing i just stated in my last post. first batch used mature Machine WS-21 also for EMALS test..

but this is indeed a big news for me, WS-19 Entering in serial production with J-35/J-35A.


one more thing i want to add.. hands down the best performance of AECC Guiyang from any AECC subsidiary. not to downplay AECC Shenyang contribution in China's turbofan industry in last decade but Guiyang exceed the expectations. a humble beginning in early 2000's and look at now. delivered WS-13E , WS-21 and newly designed WS-19 in just one decade.. also huge contribution from local government for help to build local expertise..

I don’t see any indications. Does the j-35 have any internal guns?

I vaguely recall that when the parade rehearsal photos were released, some people seemed to notice that the exhaust nozzle shapes of the J-35 and J-35A were different.

Meanwhile, if it's true that the J-35A uses the WS-19 engine, this aligns with the claim about the Cute Orca—the naval variant of the J-35 is still awaiting the vector nozzle version of the WS-19. Therefore, the J-35 is expected to undergo limited production, with mass production postponed until the vector-capable WS-19 matures.

It's not just the shape, the color is clearly different. You could go look at some photos and it's obvious

are you implying that the airforce version won't get the flat nozzles?

Yankee basically confirmed this news.. J-35A had WS-19 Engines during parade..

chief designer of WS-19 revealed. due to digitalization process we are able to shortened the development cycle of this new Engine. look like WS-19 took full advantage of being late comer in this industry. but this is indeed a sweet surprise.

THESE ARE WS-19s???

Another listener has a different interpretation.

Yankee said "Navy J35 has a more advanced engine", without specifying that it is WS19.

Uh from the Chinese excerpt either way it's the J-35A that has the better engines, be it WS-21 vs 13E or 19 vs 21.

I personally think the former is likelier.
