Thanks, hard to keep up with all the lesser visible details for us amateurs.
So currently there are:
J-15
J-15S (two seater)
J-15T( CATOBAR)
J-15D (EW)
J-15TD (EW CATOBAR)
did i miss anything? Is there a J-15TS?
EW variant is confirmed to be J-15DH. No idea what they were thinking, but that's the name from CCTV.
