Well, as far as I can tell, te Chinese are setting themselves up to use the STOBAR carriers a little differently that what the soviets intended when the design was figured out back in the late 80s for the Soviet Union.or on the other side to design the ship at all.
They were not intending to use the Kuznetsov and the Varyag to conduct US style carrier operations. hey intended for them to principally protect the SSBN areas.
So, the Chinese are attempting to upgrade and make a better design out of the J-15 over the SU-33 so they can get more out of it and use it accordingly off of these two STOBAR carriers. And having that SSBN in the pictures was really interesting because it could imply of course a desire to use them for that type of operation as well.
But I also believe they intend to get the J-15 to carry devent war loads off of their carriers...but it is probably going to mean that they have to fuel up after take off if they want any decent war load.
we shall see.
Right now, they are doing more with their carrier than the Soviets, or the Russians for that matter, have ever done with the Kuznetsov in terms of working them up and exercising them...and it shows IMHO.
