As this aircraft enters service, will they completely replace the J-11 platform? Or partially? Asking because I am curious as to how long the service life of the J-11 airframes will be ...

Just a side-by-side comparison between the two aircraft...

good picture..

looks like WS-13E and WS-21 engines both have tested on two different J-35 variants..

i hope things are clear now. most of the people consider WS-21 just a improved version of WS-13 engine but WS-21 is a different machine based on WS-13 with new combustion chamber , alloys and material. apart from physical appearance both are different machines..

WS-21 single engine afterburner thrust is 9+ tons. rest we don't know much.

Pretty sure this is the first one (the one with fancy tail), judging from the apparent lack of DAS apertures on the side of the nose, the fact that the lower ridge on the nose doesn’t have exposed green primer and that its engines look more like the “first” J-35A without the rather distinctive serrated inner nozzle layer that protrudes past the outer “feathers” (I’m sure there’s a dedicated word for it but it escapes my mind for the time being)
Assuming your idea, is it possible the reason for the different nozzles may be WS-21 vs WS-19?

I would think that’s pretty likely, by it’s looks the second J-35A that debuted yesterday had more or less the same engine as the naval variant, and if the naval variant used ws-21 then it only makes sense that this visually very similar engine is also ws-21

Making a wild guess, this and the one yesterday are from the same 'series' of prototypes (i.e. similar to the J-20 202X/205X). This one is from the series testing the fancy stabilizers with different engines, the one earlier today is from an earlier series testing avionics only.
