Not sure if this has been covered much in English news reporting yet, but it was pretty much officially announced they will be getting provincial level names just like the proper aircraft carriers. Namely that also includes our five autonomous regions plus our first tier municipalities alongside just the provinces.Do they have names yet?
This has actually caused quite a bit of stir on Chinese forums, which had many users believing it was too much for just helicopter carriers and expressing disappointment about how their provinces might never get used for naming proper aircraft carriers.
My best guess is they might be named after inland provinces rather than coastal provinces.
