Ship Class Code

A Ship Class Code or Starship Class usually represents one or more production runs of the same starship design. Ships within a class are usually given similar names.

• For a detail of the Classes of Starships see the description in the individual Military Starship Types and Civilian Starship Types.
• This hierarchical designation is also known as Ship Class, Ship Class Code, or simply Class.

Description (Specifications)

A class is usually named after the lead ship; that is, the first ship of that class. This is usually the ship with the lowest hull number, but may also be the first ship in commission.

• A class should not be confused with a type (see Military Starship Types and Civilian Starship Types). A type of starship (e.g. Battleship) will have several different classes or designs made that fit that type. Some confusion in terminology is in common use, e.g. when referring to a "Battleship Class" ship (…strictly speaking this is an error).

Imperial Ship Classification Synopsis

The basic system of ship classification and organization for ships within Charted Space and particularly within Imperial Space works on a simple hierarchy of mission (generalized use), type (specific use), class (very specific use), model (technological level), and lot or bloc (production run):

Imperial Ship Classification
#	Level	Designation	Synopsis	Example/s
1.	Ship Mission Codes	SUPRACLASS	MISSION	Free Trader AKA Merchant It is also known as Ship Mission, Ship Mission Code, Mission, Ship Hull Designation, or Supraclass.
2.	Ship Type Codes	SUPERCLASS	TYPE	Type A class Free Trader It is also known as Ship Type, Superclass, Ship Type Code, Craft Type Code, or simply Type.
3.	Ship Class Codes	CLASS	CLASS	Beowulf class Free Trader It designation is also known as Ship Class, Ship Class Code, or simply Class.
4.	Ship Model Codes	MODEL	TL & Model	TL-14 Beowulf Build Models aren’t always mentioned, but if they are, they are usually referred to by a TL designation.
5.	Ship Bloc Codes	LOT or BLOC	Named Ship	“The Lonesome Wolf” of ‘Bloc 312-1115d’ Ship Lots or Bloc Codes are rarely used except by naval shipyards, patrol craft, and the like. They are recorded in the ship’s computer as well as a number of places on the hull.

Overview of Imperial Ship Classification

Imperial Ship Classification
#	Level	Example	Remarks
1.	Supraclass (Function)	Dreadnought	It’s the largest organizational grouping by a generalized function or mission. For instance, battleships and cruisers have different generalized missions although they can perform many of the same jobs.
2.	Type (Superclass)	Type BB class Dreadnought	It’s a larger type grouping by a specific function or mission. Different kinds of battleships or types may perform different yet broadly similar missions.
3.	Class (Ship)	Tigress class Dreadnought	The ship itself is synonymous with a class. The first produced version becomes the class namesake under most practices. It has an even more specific mission that the craft type code (type) or superclass.
4.	Model (Version)	TL-15 Tigress Model 1105-Q3-9PR	This classification may include incremental improvements often as a result of TL advances. Some classes of ships can be built at several different TL’s. For instance, the ubiquitous Beowulf Free Trader has builds from TL-10 to TL-15.
5.	Lot (Block)	Block 365-1105 Reg-A-4702-4826-9931	This classification is also known as a Production Bloc. Blocs may have differences from lot to lot. Sometimes aftermarket or post-production modification (customization) may yield very different ships from the originally manufactured ship class.

History & Background (Dossier)

Ship Class Standardization

Ship Classes: Once a ship is built, a certain familiarity with the requirements of construction is gained by the building crews, and a shipyard can then produce such ships more rapidly and with greater efficiency. Additional identical ships built following the initial ship in a class can be completed in 80% of the original time at 80% of the original construction cost.

Ship Class Namesakes

Namesakes: Ships of a class are named to show this relationship. For example, the first ship in a series of small, swift escort vessels might be called the Gazelle, prompting the formation of the Gazelle class of close escorts. Other ship names in the class could be Reindeer, Kudie (for Kudebeck's Gazelle), Antelope, Unicorn, Pinto, as well as any of the many other names for swift herbivores.
