*Abbreviations are derived rather than official, and some sub
- Some ships have additional unique types, but with no impact on types' mechanic behaviors
- See here for a complete classifications list.
Battleships & Fast Battleships share the hull classification, BB.
Light Aircraft Carriers & Standard Aircraft Carriers are termed 正規空母, or Fleet Carriers, to distinguish them from Escort Carriers or other carrier types. This term sometimes refers only to Standard Aircraft Carriers.

Exceptions

Training Cruisers & Torpedo Cruisers do not count as a Light Cruiser for expeditions or branching rules requirements.
Similarly, Aviation Cruisers & Aviation Battleships do not count as a Heavy Cruiser & Battleship respectively.
Some ships like the Chitose-class and Taigei have remodels shifting their ship type, and sometimes even their class and their name.

Ship Stats & Remodels

Each ship have a given set of stats, affecting its combat behaviors. Those stats can be modified via Modernization, Leveling (including Marriage), Remodeling, or by simply equipping said ship.

See here for more details.

Most ships remodels have 改 (Kai) added in their name, which stands for Modified, Revised, Improved, or Altered in Japanese. For the 2nd remodel, ニ (Ni), 2 or Second in Japanese can be added.

Some ships can also have variations depending on their nationality, for special remodels, or may even be renamed after a remodel.
This naming scheme can also be found on some equipment.
