Possibly related, but @huitong seems to be increasingly convinced that the batch 03 J-15s are of the J-15B variant and that they'll serve on the Type 002.
From his blog:
The latest image (February 2020) suggested that the 03 batch (J-15B) is being built for the the indigenous Type 002 aircraft carrier.
Perhaps the lack of a reinforcing strut is indicative of this.
