WS-21（improved WS-12) has little to do with RD-33, thrust obviously is at the same/close level as EJ200.

- Start date
That's my mistake. I confused WS-13 with WS-21, but the current WS-21 is still far from EJ-200. I'm still looking forward to the new advanced medium thrust engine WS-19.
Are you sure we know enough about ws-21?
(And just to make sure, thrust of RD-33MK is within 2 kn from ej-200)
Its specific parameters are still unknown, but it was improved from WS-12, in which reference was made to the experience of WS-13E (a domestic alternative power scheme for FC-1 and JH-7), but the parameters of EJ-200 are outstanding in the medium thrust engine, which is comparable to the latest improvement of F-414. In comparison, the technical route of WS-21 and many revealed data show that it still has distance.That's why I hope to see WS-19
What technical data
Idk where ws-12 came from, it's long dead. General consensus was that ws-21 is more or less f-414 version of ws-13.
"Outstanding parameters" are still there(though it's a 30 yr engine at this point), but wet thrust is nothing magical. It isn't the only parameter there's to engines.
Just a chart,exhibit at the symposium of aviation industry enterprises from China
This is proven to be inaccurate though, WS-19 should be at the very end of the graph at near 12000kg and 10+ TWR
That's its full version, just like the 23.5-ton full version in the F-135 program(but it's already be shelved).
Not this chart again,
This is at most a conservative baseline, not tech data of the current engine.
