Lol, can't debate on points and facts but resumed to personal attack of zip my mouth?
Well for the record, I posted the link of your "first response" below for everyone 's check:
J-35A fighter (PLAAF) + FC-31
So, please enlighten me in your above"first response", which parts respectively deny the following facts I raised:
1. Ms Huang designed multiple engines, not only WS19 and WS21
2. Ms Huang is also the designer of FWS17 which is equipped with afterburner suitable for shipborne JL10 trainer in PLANAF service.
3. JL10 participated the 93 parade, alongside J35.
4. Only weapons entered pla services were featured in 93 parade, not prototypes in development.
If you can't deny any of the above, just accept that the chance of WS19 entering PLA service as early as 3 September 2025, is much lower than the chance of ws17 powered JL10 that flew during the parade.
