And it has been pointed out multiple times that that 003 is a derivative of the Kuznetsov class, not that it is identical to the Kuznetsov. Either understand what a derivative is or quit strawmanning.
A derivative is a term you use. It is not used as a common shipbuilding term,
1) Class by types -- ship classes are categorized by their function, size, and design such as container ships, oilers, destroyers, etc.
2) Class as a particular design --
Kuznetsov is the first and thus used as the name of its design class.
There is no "derivative" as a proper shipbuilding term.
There are type classes, named classes, subclasses and variants in the shipbuilding world. The
Shandong and
Vikrant -- though built by different nations -- are both ships of the STOBAR type class.
The
Liaoning is a sister of and thus of same named class as the
Kuznetsov.
The
Fujian is a CATOBAR and thus a completely different type and class from the STOBAR
Kuznetsov.
It is nonsensical to use an ambiguous term like "derivative" because every modern ship is derived from iron hulled vessels in the late 1800s.
