the link A.Man posted is actually quite significant.
Just some really quick thought on these photos. We finally get some really nice photos of production J-11BS for PLANAF and PLAAF (I believe the light colored ones are for the navy and the dark colored ones are for the air force). Since the canopies are covered, so I can't tell if they are all J-11BS, but the uncovered ones are all so. I'm not sure if they have just stopped producing J-11B and shifted to J-11BS, since J-11B can't compete with the cost/capability ratio of J-10A and J-10B. J-11BS will be also tasked with anti-shipping missions and long range strike missions that J-10 simply don't have the payload/range to do.
Good to see that the engines on these flankers all seem to be WS-10A. From the J-11BS still in primer, it looks like the vertical stabilizer is all made of composite material.
Now, what I didn't post is a picture showing a J-8II in primer. I guess they are still in production too.
