PLAN Fleet supply vessels

It would make sense yes. That is why I find the seemingly continued pause (against persistent rumours) so puzzling. But maybe they are confident they can put these AORs together far more quickly and crewing/training requirements are more trivial allowing quicker absorption into the active force when needed.

Given the present size and future fleet development of the PLAN, China will need more AORs and AOEs, especially when frequent long voyages into the "true blue" IndoPac are expected going forward.
