WS-10 is currently in use by four type of PLAAF aircrafts.

The first to use WS-10 is J-11B. WS-10 was test flight on a J-11 in 2004.

While J-10B was test flight with WS-10, its production aircraft didn't use WS-10 yet. Early batch of WS-10 did have reliability issue, but that was around a decade ago.

J-16 is the next aircraft to use WS-10.

J-10C didn't use WS-10 in its initial batch. But later batch started to use WS-10.

J-20 batch production also switched to use WS-10C.

J-20 first flight with WS-15 happened around Jul 5.

Y-20 is currently testing with WS-20. Should be ready by next year.
