Ship Mission Codes are used somewhat inconsistently throughout Charted Space to identify ships.

Starship:

Description (Specifications)[edit]

The List of Hull Designations comprises an alphabetical list of the starship and spacecraft hull classification types (Superclass letter designations) to identify the type of a ship. The base description for the hull designations comes from Ship Type Codes.

  • The combination of a letter designation and hull number are used by the Third Imperium to identify Imperial vessels uniquely. A heavily modified or repurposed ship may receive a new designation, and either retain the hull number or receive a new one. Also, the system of letter designations has changed a number of times, so ships' alphanumerical designations sometimes change without anything being done to the physical ship. Some of the ship hull designations listed here may not be presently in use.
  • The Imperial Quick Ship Profile (QSP) is an abbreviated form of this measure.
  • Additionally, due to changes over the millennia, some ship hull designations may be duplicated with alternate meanings. In other words, some letter codes have multiple meanings.

Imperial Ship Classification Synopsis[edit]

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
2. Ship Type Codes SUPERCLASS TYPE Type A class Free Trader
3. Ship Class Codes CLASS CLASS Beowulf class Free Trader
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[edit]

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 Battleship 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)[edit]

If one thing can be said about Charted Space, it might be that non-conformity reigns supreme. Even within the runaway superpower of the Third Imperium, the prototypical Feudal Confederation, naval fleet organization has often been haphazard. At least three major naming and organizational schema have been used since the Holiday Year.

All major race navies use similar yet significantly different systems.

Master Imperial Type Codes[edit]

These codes became predominant by 1105 and started being phased in after the (990-1002) Solomani Rim War.

Alternative Ship Type Encoding[edit]

There are a number alternative ship type encoding.

  • Starship type codes are between one and four or more characters long. In order there is an optional race or empire qualifier, a required primary mission identifier, and an optional mission qualifier.
  • MegaTraveller has a subtly different set of ship type codes available. Nothing taken away, but a few additions are made.
  • See Military Starship Types and Civilian Starship Types for more information.
  • The full list is under the MT Primary and MT Qualifier below.

Mid-Imperium Ship Type Codes[edit]

The First Civil War really shook up the Third Imperium and caused naval strategists to rethink fleet organization. By the year 700, this new schema had been implemented.
