The J-15 story is getting more and more confusing!
... and now here is J-15 no. 72!
While the renumbering from 1xx numbers to 01-24 made sense and the additional Batch 03 fighters logically became No. 30+, the No. 60 modex J-15 were or are still unusual.
My feeling tells me that we see a second squadron under construction with numbers 01-35 in the first wing and no. 60-xx in the second.
