It's probably safe to say at this point that 001 = CV-16/Liaoning and 002 = CV-17/Shandong, with "001A" being a work of internet fiction.
MAybe...maybe not.
It is what News outlets, all sorts of big and little fish, and people have used for several years now.
Clearly in terms of the way that various systems have been named, when you have a particular class, the class has a number and modifications to the class get a new letter disgnator.
The 2nd carrier is clearly a Lioaning Class ship. it is NOT sunstantially different but does have a few improvements.
There is notre differences between the Type 052C and Type 052D, yet they are stil Type 052s.
So, the new carrier, which may well be CV-17...we will see later...is clearly of the same class vessel as the Liaoning.
The CATOBAR carrier will truly be a new class.
As I stated on the CV-17 Thread...
We have had numerous sources tell us that the vessel is Type 001A and is CV-17:

So, until we have some offical word from the Chinese government or the PLAN itself, we will leave it as is.
If you have a link from an official PRC or PLAN source, please post the link so we can read it, or translate it if necessary.
Until then, we will leave it as is has been being called here and elsewhere for the last couple of years.
