If 003 inherits shandong´s isle, and it seems that it will, i dont think that they will be much happy about it. That isle is huge, and takes a lot of real estate in the carrier.
It doesn't. It has a newly designed isle on its own. Its already been seen being tested as a mockup with actual equipment on, somewhere in Wuhan. Its more compact to start with, with four panel dual band AESA, possibly with two large panels on the side for ECM---these two techs are inherited from the 055---and a large mast with multiple small planar phase arrays on it, possibly a combination of ESM, IFF, and CEC. Its topped with an ESM stalk and TACAN, which also looks like a 055 part.
The new island mockup for 003 is built upon the previous mockup for 002. You can still see the bridge for 002 to the left, followed by the bridge for 003. That's a sizable chop of area.
The island is used with fan created CGI models of the ship, namely the island on a generic looking carrier.
