Ship class
From Wikipedia, the free encyclopedia
A ship class is a group of ships of a similar design. This is distinct from a ship-type, which might reflect a similarity of tonnage or intended use. For example, the USS Carl Vinson (CVN-70) is a nuclear aircraft carrier of the Nimitz-class.
In the course of building a class of ships, design changes might be implemented. In such a case, the ships of different design might not be considered of the same class; each variation would either be its own class, or a subclass of the original class (see County-class cruiser for an example). If ships are built of a class whose production had been discontinued, a similar distinction might be made.
Ships in a class often have names linked by a common factor: e.g. Trafalgar-class submarines’ names all begin with T (HMS Turbulent, HMS Tireless, HMS Torbay); and Ticonderoga-class cruisers are named after American battles (USS Yorktown, USS Bunker Hill, USS Gettysburg, USS Anzio).

[edit] Class naming conventions
The name of a ship class is most commonly the name of the first ship commissioned or built of its design. However, other systems can be used without confusion or conflict.
[edit] United States
In the United States Navy, a class is always named after the lead ship; that is, the first ship of that class to be approved by Congress, which, due numbering conventios, is almost always the ship of the class with the lowest hull number..
[edit] Europe in general
In European navies, a class is named after the first ship commissioned, regardless of when that ship was ordered or laid down. In some cases, this has resulted in different class names being recorded in European references from their American counterparts - for example, European references report the Colorado-class battleships of the United States Navy as “Maryland-class,” since the USS Maryland was commissioned over two years before the USS Colorado. Some Italian warship classes were named after the naming theme, eg, Capitani Romani class cruisers.
[edit] United Kingdom
The British Royal Navy has used several methods of naming classes. In addition to the accepted European convention, some classes have been named after a common theme in the included ships' names, eg, Tribal class destroyers, and some classes were implemented as an organizational tool, making traditional methods of naming inefficient. For instance, the Amphion class is also known as the A class. Most destroyer classes were known by the initial letter used in naming the vessels, eg, V and W class destroyers. Classification by letter also helped to conflate similar smaller classes of ships as in the case of the C-class destroyers of 1913 whose names spread across the alphabet. Since the end of the Second World War, Royal Navy ship classes have also been known by their “Type Number.”
[edit] Russia/Soviet Union
Russian (and Soviet) ship classes are formally named by the numbered project that designed them. That project sometimes, but not always, had a metaphorical name, and almost always had a NATO reporting name. In addition, the ships of the class would be numbered, and that number prefixed by a letter indicating the role of that type of vessel. For example, Project 641 had no other name, though NATO referred to its members as Foxtrot class submarines. In contrast, Project 667AM was known in Russia as Navaga, a type of cod, and was given the NATO reporting name Yankee-II. One boat of that class was K-219—the “K” standing for kreyserskaya, “cruiser”—which had no other name.
[edit] Germany
The West German Navy (Bundesmarine) used a three-digit type number for every class in service or in advanced project state. Modifications were marked with a single letter postfix. After reunification the German Navy (Deutsche Marine) kept the system. Informally, classes are also traditionally named after their lead ships.

[edit] Use in fiction
The American class naming convention is also used in some American fiction. For example, the USS Enterprise (NCC-1701-D) is a Galaxy-class starship, which is named after the USS Galaxy (NCC-70637), the first ship produced of the design.
