That is at this point still possible. But has anyone seen any clear evidence of a catapult program in China ? Steam or EMALS a like ? A full CATOBAR carrier would mean that they have to retrain their pilots and deck crew. And maybe even redesign the plane. A STOBAR/CATOBAR combo is at the same time progress and playing it safe. If they have issues with the deck crew or pilots or plane. Then the carrier doesn't have to sit idle for long periods of time and instead just operate it like a STOBAR carrier as they have trained and working to fix the problems at the same time.A full out catapult carrier (without the ski jump) would be a most welcomed surprise.
It will be a disappointment if this carrier is just a copy of the Admiral Kuznetsov class. I certainly hope that they will have brought changes and improvements to the design. Like a wider flight deck bigger hangar deck and a smaller island structure at the least. A catapult on the angled deck will be a huge bonus.
