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

Please refer to the following AAB Library Data for more information:
Starship:

Description (Specifications)

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.
  • 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

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

'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)

The Vilani Imperium and its successor, the Ziru Sirka, were both large, stable bureaucracies that kept the order for many millennia. They propelled the Vilani people from a planetary bound existence to one of the largest interstellar empires known to sophontdom. The Vilani achieved this due to many reasons and one of the foremost of these reasons was excellent organization, asset tracking, and logistics of their many spacefleets. The First Imperium successfully used the system for several millennia before running into the Terrans and their balkanized chaos. In some ways, the early Terrans were unified, but in many others, they were completely disheveled and disorganized along historically nationalistic and cultural lines. A number of competing fleets each used their own systems of ship organizations and the progenitor organization of the Terrans, the United Nations, was a complete basket case.

After the Terrans won the Interstellar Wars and established the Second Imperium of Rule of Man, they tossed out the older, well-established vilani system of ship organization and tried to institute their own. Much like the United Nations a chaotic mess ensued and numerous competing systems existed side by side, often contributing to mix-ups and sometimes even fatal accidents. Within a few decades, planetary and subsector fleets officially used Terran ship organizations systems, but quietly and unofficially used the traditional vilani methods. These methods had stood the test of time and regime change.

Even after the fall of the Second Imperium and the mess of the Long Night, the ship organization system persisted in use. Those pocket empires which retained spaceflight and even starflight, continued to use the old ways, which continued to work. The Sylean Federation actively used the system and when it grew into the Third Imperium, the system was a tried a true part of human space navies. The system was greatly complicated and confused by Terran additions during the Second Imperium, but it is functional today and most spacers are familiar with the system, even travellers from non-Imperial polities, who use alternate systems.
