Spaceship Sizes
Spaceships in the Dominion are typically categorised into size classes based on their mass. This classification is maintained by the Mercantile Bureau and assigns ships a designator of the form SM+<size number> (SM after ‘Size (Mass)’ [GM: It’s entirely coincidental that ‘SM ‘is an acronym for ‘Size Modifier’ in the GURPS rules…]).
The classification bands are based on the smallest possible manned ‘ship’ – a person in a spacesuit and increase in rounded multiples of three from there, as follows:
- A person in a spacesuit masses about 100kg and is Size 0
- The next size, SM+1 is about 3 times bigger – about 300kg
- Three times bigger than that is about 1000kg – Size SM+2
- and so on…
In practice, the smallest single-seat fighters are SM+4 (10 tonne), the big bulk freighters that operate on standard routes are SM+12 (100,000 tonne) and the largest navy ships about SM+14 (1,000,000 tonne)
The Legion tends to follow the Mercantile Bureau’s number classification, but typically has names for the size classes. Although, this is not a pure classification but conflates the concept of function into a single label.
By contrast, non-military ships are more usually referred to by their size number or mass and a label descriptive of their function. For example, a ‘Size 9 Freighter’ or a ‘3 kilotonne freighter’ rather than a ‘frigate’.

See here for Legion Navy command rank requirements associated with different Size Classes.
Spaceship Build Classes
In addition to the Size Class, spaceships have a Build Class – because there’s nothing like using the same term for different things to keep people on their toes.
A ship’s Build Class refers to its design. All the ships built according to the same design belong to the same Build Class.
In most cases the Build Class name and the name of the first ship built to that design are identical.
Spaceship Names
(with apologies to T S Elliot)
Naming practices for individual ships vary between operators.
Traditionally, where a ship is given an individual name, that name is in some way related to the Build Class name. For example, Clarifier Class Research Ships operated by the Vizierate are named Clarifier, Illuminator and Enlightener. This is not always followed in practice.

- The 10 kt (SM+10) Elizabeth-Class FreighterCyprinidae
Vizierate
The Vizierate sometimes adopts the Legion names for its ships’ Size Classes – usually the less combative descriptors – but also uses other terms, for example, the largest ships operated by the Vizierate are the SM+12 Clarifier Class Research Ships – the Legion doesn’t have ‘Research Ships’.
- The 100 kt (SM+12) Clarifier-Class Research Ship Illuminator
- The 1 kt (SM+8) Maldemar-Class Sloop Maldemar 732
- The 300t (SM+7) Snark-Class FTL Courier Snark 416
Mercantile Bureau
- The 100 kt (SM+12) Conveyor-class Bulk Freighter Riches of Aden
- The 30 t (SM+5) Yawl-class Jolly Shuttle Treasure 1(Auxiliary to Riches of Aden)
Trade Bureau
- The 100 kt (SM+12) Conveyor-class Bulk Freighter Porter Spielvogel’s Trader
- The 30 t (SM+5) Yawl-class Jolly Shuttle Spirited Yawl (Auxiliary to Porter Spielvogel’s Trader)
Legion
- Every ship in the Legion is assigned to a fleet
- Even if the ship never operates with other ships, it still has a notional fleet assignment
- Legion fleets are numbered according to a set of logical rules
- Each numbered fleet also has a one-word name that forms part of its fleet emblem and identity
- Each vessel assigned to the fleet has the fleet name as the first part of its ship name
- After the ship name, the ship is identified by a string of alpha characters that indicate
- Size Class
- Build Class
- Construction Location
- Construction Serial Number at that Location
- The string of alphas is constructed such that it is always pronounceable as a word, even if (as it usually is) that is a nonsense word
- The 10 kt (SM+10) Hand-class Destroyer Norhand
- The 300 kt (SM+13) Bastion-class Carrier Bulwark (fleet name = Zealous ZAZEP)
- The 100 t (SM+6) Inspector-class Pinnace Zealous PUNOUB
- 7th Fleet (Zealous), Pinnace (P), Inspector Class (U), built at New Zargland (N), 37th built (OUB)

Spaceship Registry
The Legion maintains a registry of all non-Legion ships in the Dominion. These are assigned a Dominion Ship Registry ID by the Legion in addition to the name selected by their operator. The Ship Registry ID has similarities in structure to the Mer ID. It is of the following form:
<Operator Type Code>-<Registration System Code>-<Registration Region Code>-<Registration Date>-[<Auxiliary ID>-]<Check Code>
Format: A-AX-XXX-NNNNNN-[NNN-]-A
- The Operator Type Code is determined from the table below.
- The Registration System Codes come from the standard list of system codes.
- In practice, the Registration Region Codes are limited to places that have a Legion Cast equipped to conduct ship inspections and registration. Note that while ship registration is a sufficiently infrequent event that the registration date can generally be used as a unique identifier, should multiple ships be registered on the same Cycle, the Legion has a list of alternate Region Codes for each Cast to be used to make the registration unique.
- Registration Date is shown in Cycles.
- A ship may be registered as an Auxiliary Craft of another ship. If so, it will be assigned a three-digit Auxiliary ID (usually 001 and counting up). The Registry ID will otherwise be the same as the parent ship (though the presence of the Auxiliary ID may alter the Check Code).
- The Check Code will be one of the Dominion’s standard check code values, ie {Z,W,T,TH,F,V,S,N,E,I}
As noted, the Registry system does not apply to Legion ships. In situations where a non-Legion ship would use a Registry ID, a Legion ship would use its Fleet Name.
If a ship changes Operator or is re-registered for any other reason, an new Registry ID will be issued.
Ships are required to display their Registry ID on their hull in accordance with set of regulatory specifications published by the Legion that would be capable of stunning a small creature if the hardcopy were used as a weapon.

(a) Unused since Overlord Kate dismissed the Underlords.
(b) The Vizierate, Wardenate and Legion have gone back and forth over the issue of Wardenate registry for many kiloCycles; the contentious issue for the Legion being that Wardenate ships are permitted to be armed under the Codex.
Fees
Operators in the Private group are charged a fee for issuing the Registry ID, which entitles the ship to use facilities at Dominion Ports and transit the Overlord’s space (there is a notional equivalent for other operators, but that is all handled through the arcane arts of the Finance Bureau.)
The standard fee (which may be adjusted, again based on a thick sheaf of Legion regulations) is ʄ25,000 per ton of ship for M- and P-types and ʄ10,000 for Y-type registries for one kiloCycle, payable in advance.
