I went back to check on fzgfzy's 001A thread today. Some guy still question whether this hull is 001A or just a bulk carrier just like here in SDF. He said he will delete his ID if this is not 001A next year. (That's a pretty big bet for a mod and some sort of funny tradition in Chinese military forums when members challenge each other with the loser/wrong side deleting their own ID/forum user name. He say this is a open bet for anyone who wish to bet with him. ( Kind of like put your money where your mouth is.)
He said that big hole area is the engine room. And the highest deck you see on the pic is actually one layer/level below the hangar deck. ( You don't see the hanger deck section because this picture is not the newest picture.) So.. the hanger deck modules might already built and ready to be integrated by now(Or already did), we just don't have updated photos of it.
