"Ship classes" refers to the common practice of building multiple ships using a same or similar design. The design is then called a "class", and the class is often named after its 1st built or commissioned ship, or the initial design's code name. Ships built under the same class are then called "sister ships".

In Kancolle, several "classes" are instead referred to by their "type" (e.g. the Number 2-class is referred to as the Type D Kaiboukan).
Some informal classes are also sometimes used, such as the "Special Type Destroyers", or the ones listed below.

Class Changes

The following is a list of cases where the class of a ship changes upon remodeling.

This change can have an impact on mechanics asking for a specific class, such as Quests.
This can also affect the impacted ship's card, looking as if they were not remodeled, despite being already remodeled (see here).

Base Classes	Ships		Remodeled Classes	Ships
Kasuga Maru-class	Kasuga Maru	[math]\displaystyle{ \rightarrow }[/math]	Taiyou-class	Taiyou
Kasuga Maru-class	Yawata Maru		Taiyou-class	Unyou

Courageous-class	Glorious/Glorious Kai BC		Glorious-class	Glorious/Glorious Kai CV

Library Only Classes

The following is a list of cases where the class displayed in the game Library of a ship is different from the real ship's class.

None of those cases has any gameplay effect.
Those cases are purely cosmetic, often reflecting IRL concepts, or being fully made-up.

↑ Sometime, the 2 later ships of the class are considered as Ariake-class instead.
↑ Fuyutsuki in the game is considered an Akizuki-class and not a Fuyutsuki-class for no apparent reason.
↑ Unreleased yet.
↑ The Kai Akizuki-class was planned but never built, and serves as a template for Akizuki-classes Kai Ni.
↑ The Kai Shimakaze-class was planned but never built, and may serve as a template for a future in-game remodel.
↑ The Tachibana-class has been anounced in an interview.
