If CV17 wouldn't carry more aircrafts than the Liaoning, then what did the new layout improve? Aircrew working space maybe?
The US Navy does not carry its full wing in the hanger...and neither will the Chinese.
In addition, it is unlikely that they would ever fill the hanger like you see above. There has to be room to work on the aircraft...that is why the hanger is there.
The Liaoning can comfortably carry, meaning on deck and in the hanger, up to 24 J-15s, and then probably 12 helos. The new carrier will, in all likelihood have the same capacity. They may have more room n the hanger, they definitely will make improvements in the logistics of the carrier and in the spaces wherever they can. But we already know it is meant to be the same type of carrier as the Liaoning.
Having two of them, that operate the same, is going to save them a lot of money in logistics and in training and with their initial policies and procedures.
When they go to the CATOBAR carriers, they will shift somewhat, and you can bet that they will build probably two of those for the same reasons...and the shift from a conventional CATOBAR carrier to a nuclear one, which I believe will be the 3rd step, except in the propulsion spaces, will be very similar to the conventional CATOBAR carriers they build.
