Hmm ... a new photo of a "B" with maybe 1034 !
However the first "B" with the IFR-probe ... so either a forth prototype or the first one ready for delivery ... but still with the AL-31FN.

That's off the same picture as the one showing what looks to be China's fixed wing carrier AWACS.
So either CAC is working on that as well, or this J10B is at some sort of testing and evaluation facility outside of Chengdu.
It would be an interesting development in either case.
Naval J-10's
How do you know its navalized version? All I see is a basketball hoop in front.
The unit markings are in red.
And they aren't "navalised" in the sense of carrier ops, just that the navy operate them. From land airbases.
