Editing Encyclopedia:Naming conventions (ships) (section)

===Ship type===
The type of ship that comprises the class: aircraft carrier, trawler, frigate, icebreaker. Do not be overly specific in the type:
* {{xt|aircraft carrier}}, not {{!xt|light escort fleet assault carrier}}

Use the singular form of the ship type:
* {{xt|submarine}}, not {{!xt|submarines}}

Uses of the class name as a noun are not [[hyphen]]ated, while adjectival references are hyphenated.  Article names that follow the form just described are adjectival because the compound phrase made up of <class name> and "class" modifies the noun <ship type>.  As such, article titles should be hyphenated:
* {{xt|''Evergreen State''-class ferry}}, not {{!xt|''Evergreen State'' class ferry}}
* {{xt|Tree-class trawler}}, not {{!xt|Tree class trawler}}

In article titles and in article text, use a [[hyphen]]; do not use an [[En_dash#En_dash|en dash]] (–) or [[Em_dash#Em_dash|em dash]] (—).
* {{xt|Tree-class trawler}}, not {{!xt|Tree–class trawler}} or {{!xt|Tree—class trawler}}
