We saw this dry dock being built, used for Liaoning and IIRC used for repairing one or more bulk carriers. This ship is I think the first one being built in this dock. That too suggests this is 001A. Agreed?
There are lots of compelling factors at present which may suggest that this could be 001A, but we'll only get complete, 100% confirmation once the island is literally hoisted up and welded to the rest of the hull.
The only major reason why some believe that this may be a bulk carrier is that the compartments on the hull are not closed. But we'll only get confirmation that this hull is not a carrier (or any other military ship for that matter) once it gets launched and turns out to be a bulk carrier or whatever other kind of cargo ship.
