Current practice on codes "armored" and "gunned" is for their application to merchant ships or auxiliaries serving with the RN or RQS. These codes are no longer applied to military line ships, as they are superfluous and unneeded. The qualifier "Imperial", while still present on some older classes, was no longer applied after 1176, and only classes built before the Collapse are entitled to bear it anymore. Non-Assigned qualifiers are intended for future use. "Heavy" and "Imperial" have been replaced with the terms "Hunter" and "Intruder" following the 1169 White Paper on Regency naval strategies.
Small craft codes are special and are handled under a "parenthetical" method.
Regency Naval Definitions: The Regency Navy recognises four categories around which it organises its forces. These four categories are: Combat, Combat Support, Logistical Support and Military Spacelift. Each category is further broken down into seperate subcategories reflecting specific roles in the overriding main category. And those subcategories are lastly divided into different rates, and the rates into classes.
The Combat category is divided into four subcategories: Hunter, Intruder, Protector and Scout. These are not firm Solomonic divisions, but merely design objectives built within a ship. There is considerable overlap, particularly between the Hunter and Intruder roles.
1. Hunter: refers to ships that fill both the strategic defense role. Hunters are usually designed to protect against Intruders, deflecting or destroying encroaching enemy fleets away from bases and vital internal worlds.
In Regency service, ships with the term "Hunter" as a qualifier usually mount the heaviest armor possible, the largest spinal mount or spinal rosette possible, and have a jump range of 3-4.
2. Intruder: Ships designed for the strategic offense role, specifically the seizure or destruction of enemy bases and worlds.
In Regency service, ships with the term "Intruder" as a qualifier usually mount a number of parallel mounts, carry considerable supporting small craft, and have a jump range of 4-5.
3. Protector: Ships designed for the tactical and operational defensive roles. These are ships designed and tasked to protect space commerce, and to protect specific tactical or strategic supporting facilities within a system or base.
Protectors are limited to rates D through G, have a jump range of 3-4, optional spinal mounts, and some limited form of offensive ability.
4. Scouts. Also known as the Scout/Screen role. These ships are information gatherers or contact units tasked to provide early warning and continuing realtime intel to the Main Battle Fleet (MBF).
Scouts are limited to rates D through G and S, and must have minimum 3G and J-2.
Regency Combat Classes and Rates: Regency designation of naval craft are divided according to their combat role, and further subdivided by subcategories or chronological order. The TL of the vessel is adjoined to this, and finally a letter denoting the numerical progression of that class and rate. For example a BB-13C is a Battleship, TL13, and the third class of such ship in active duty at that TL recognised by the Regency/Imperium. Note emphasis on "active duty", which means that ships are often reclassified as other vessels are decommissioned or transferred. The code (PC) is used to indicate a post-collapse design.
Please note: This system of classification applies only to the Regency Space Forces, not to Regency Planetary or Subsector Navys, which often have their own overlapping or non-standard classifications, often confusing and contradictory. These codes also do not apply to the navies of surrounding Spinward States, though a few, notably the Corellian League, the Protectorate and the Avalar Consulate, use a close facsimile of this system.
A: SUPERHEAVY SHIPS. Craft that exceed battleship displacement craft. Mostly experimental or limited production.
AH, AI- Leviathan. 2,000,000+ tons. The "superbattleship" idea brought back to life. The advent of icing technology allowed the Regency to build a limited number of these ships beginning in the 1160s, and most are limited, because of their expense, to experimental roles and defending the Regency national and sector capitols.
AV, AT- "Behemoth". Unknown ship class described in the RASAC archives leaked in 1201. Apparently a massive tender or carrier class vessel with combining frontline battle ability with carried escort and screening ships. It is unknown why this vessel was in the RASAC files, but there is rampant speculation that the navy was looking into the possibility of using Puppeteer strain Viruses similar to the Khishki's to man a small task force sized naval unit.
B. BATTLESHIPS: Defined as the heaviest primary combatant in the battleline.
BB- Battleship. 150,000-1,000,000 tons. The Regency retains the Imperial practice of classing reserve and lower tech dreadnoughts as BBs.
BC- Battlecruiser. 100,000-250,000 tons. Replaces the code BL (Light Battleship), a reflection of the short lifespan of these ships in traditional battleship roles. BCs are the most common Regency battleship rate, making up approximately 40 percent of all battleships "afloat".
BH,BI- Dreadnought. 700,000-2,000,000 tons. BI (Imperial Battleship) was replaced with Battleship Intruder, while BH (Heavy Battleship) was replaced with Battleship Hunter. Originally the Imperium rated ships above 3Gs as BI, and those below as BH. All classes built since 1133 are above 3Gs and are now classed purely as BH or BI depending upon their primary armament and jump range, which creates no small amount of confusion, even with the new system, and are termed (PC).
C. CRUISERS: Most common heavy battleline, raiding and escort unit.
CC, CF- Fleet Cruiser. 30,000-80,000 tons. Primary cruiser classes.
CH, CI- Heavy Cruiser. 80,000-150,000 tons. See "Dreadnought" above for details, as the same situation applies. Min Jump 3.
CL- Light Cruiser. 15,000-30,000 tons.
CR- Raiding Cruiser. 10,000-150,000 tons. Currently a disused category. The last CR, the CR-15B, was rerated as the CP-15E in 1181.
CS: Strike Cruiser. 25,000-75,000 tons. Min Jump 4.
CT: Assualt Cruiser. Craft purpose built for Marine SaultRons. Current classes are the CT-15A (Al-Khafji class) and CT-15B(PC) (Garrison Class).
D. DESTROYERS: Main raiding and screening units, and most common line units.
DD, DF: Fleet Destroyer. 8,000 to 20,000 tons. Most common fleet line rate. Min J-3, 4-G.
DH, DI: Heavy Destroyer, Destroyer Hunter/Intruder. 20,000 to 35,000 tons. Min Jump 3, 4-G. DM: Missle Destroyer: Any destroyer that mounts missles as its primary armament. Currently a disused category in Regency service. DR: Raiding Destroyer. 10,000 to 20,000 tons. Min 4-G. Classes recognised: DR-15A (Mandragora Class), DR-15B (Beltane Class).
DS: Strike Destroyer. 5,000 to 15,000 tons. Min Jump 4. Spinal Mount required. The Manzikert (DS-15B) is a good example of this class.
E. ESCORTS: Ships assigned to the Protector role, and designed to protect shipping and vital facilities against enemy raiders. Generally more than 3-G, and min jump 2. Many are former line ships rerated and modified.
EB: Battle Escort. Large 20,000+ ton escorts, usually mercantile cruisers assigned to the Ready Reserve during peacetime, that have a dual military-civil capacity. Most EBs continue their dual role in wartime, often acting as the main central defenders of a convoy in case of an attack.
EC: Close Escort. Small, 1,000 to 3,000 ton hulls designed to blend in with escorted ships and convoys. The Chrysanthemum was rerated as the EC-15C in 1176.
ED: Destroyer Escort. The most common pre-collapse escort rate. 5,000 to 10,000 tons displacement.
EE: Generic Escort. Rate is rarely used.
EF: Fleet Escort. 10,000 to 20,000 tons. Often obsolescent cruisers and destroyers given new armaments and powerplants and downgraded to escort roles. A good, if oversizd, example of this is the former Azhanti High Lightning Intruder Class (IF-14A) which is currently the EF-15D.
EL: Light Escort. 800 to 2000 tons. Fast and long ranged. Examples of this class include the Mosquito-E and the original Fer-De-Lance classes.
EN: Special Escort. This solely refers to the venerable Tekkatir class escort. The Tekkatir was designed specifically to escort and support Imperial special forces and Ranger units. Most of these vessels are assigned to the joint Special Operations Command.
F. FRIGATES: Frigates partially fulfill the Screener/Scout role identified in the 1169 White Paper. Along with Escorts, Gunboats and Scouts, Frigates form the vanguard of the MBF, providing intelligence, and diverting or otherwise occupying enemy scouting and perimeter vessels. While rarely equipped with spinal mounts, most frigates are 5-G and up, are heavily armed with unmanned laser turrets and barbettes, and are beginning to mount more and more small craft and RPVs to support their roles.
FF: Fleet Frigate.
FH, FI: Battle Frigate. A destroyer or light cruiser modified for the Vanguard role.
FL: Light Frigate. This class includes the variant Mosquito-F.
FM: Missle Frigate. Frigates are more likely to be involved in close quarter delaying and contact battles, where missles really come in their own. FMs include the Yataghan (FM-15E) class. All members of this classification rely upon missles for their primary armament.
FP: Patrol Frigate. This class includes the 400 ton Lauritson class (FP-15A).
FS: Strike Frigate. Frigate class intended for deep penetration strike raids and commerce raiding. 1500 to 5000 tons displacement, min. J-4.
G. GUNSHIPS: Light battle or security ships of less than 3000 tons displacement. never intended to be in MBF actions. Usually used for the Security/Screening and light Escort roles.
(Author's note: I know that, in order to suspend disbelief, and create the impetus for really cool running space battles, as well as make military craft accessible to players, the powers that be decided to populate the Traveller universe with these kinds of craft. In actuality, small warships like these will be uncommon within line service. Or used as a utility craft aboard a much larger warship, kind of like being an armed cutter or lifeboat.)
GF: Fleet Gunship. 300 to 1000 tons.
GG: Heavy Gunship. Gunboat of 1000+ to 3000 tons displacement.
GL: Corvette. The Corvette, like the Sloop below, is designed for multiple roles. These include policing, rescue, piracy supression and Quarantine enforcement. Unlike sloops, the Corvette's emphasis is on space roles, and firepower projection, which is why few of them possess ancillary small craft. Includes the Valor (GL-15A) missle corvette.
GP: Patrol Gunship. This class includes the classic Patrol Cruiser (PG-15A) and the new Barekdoldin class (PG-16A). Commonly known in Regency service as "Pig Boats." This group also includes the new Praetorian "pursuit cruiser", a high-g TL15 updating of the Gazelle Escort.
GS: Sloop. Small escort or intruder vessel designed for multiple roles. The Fiery (GS-14C), her TL16 daughter the Luminous Class, the Faith class cutter (GS-15B), and the Gazelle (GS-14B) are rated as Sloops.
GU: Multiuse Gunship. Small gunship designed to carried by a larger craft, acting as a large landing craft, utility shuttle, boarding craft or BVR (Beyond Visual Range) targeting and relaying. Most are 100 to 400 tons displacement, and are usually carried aboard rate A through D craft.
H. ASSAULT SHIPS: Craft designed for the carriage, delivery and support of ground or ships troops to an objective. Most H class ships are from 400 to 25,000 tons, able to deploy a large force of troops on an unprepared surface or water, or grapple and remain attached to any existing spacecraft.
HA: Armored Assualt. 400 to 2000 tons displacement. JDs are not required. HA's are boarding assualt ships, designed to pursue, overtake and grapple with another ships. Rare in Antebellum times, these craft have an important role in an age of Viral infected spacecraft. Most of these ships are armored to take a point blank hit from 450 MJ unmanned laser barbettes.
HB: Battle Assualt. These are usually first wave assualt ships designed for the dropping of assualt infantry and Marine Units. Their emphasis is on support of infantry units, and have a large small craft stable. Few are more than 10,000 tons displacement.
HT: Assualt Transport. The large assualt ships designed to directly land a taskforce on a planet. Can carry, at minimum, a reinforced armored infantry battalion and its supporting elements. Older HTs are often rerated as Ro-Ros in strategic spacelift roles.
S. SCOUTS. Craft designed specifically for the Scouting/Screening role. Range from the traditional Suleiman class Scout, to large Scout Cruisers.
SC: Scout Cruisers. Large, 5000+ ton ships designed for force recon, or support of intel gathering operations. Many are capable of directly carrying smaller scout ships, SOF shipping and remote drone vessels. Many are equipped with spinal mounts.
SF: Fleet Scout. A scout ship attached to primary MBF. Usually 800 to 2000 tons displacement.
SJ: Fast Scout. A scout ship of 4G+ performance.
SK: Scout Courier. A scout ship designed for light scouting and communication relay duties. Includes the classic Suleiman (SK-15) class.
SS: Strike Scout. Scout ship designed for TD and SOF operations.
T. TENDERS. Though technically not a line unit, the tender's carried strike force gives it its offensive punch, and is an indespensable part of its assigned task force. A tender is any ship that carries more than two vessels of more than 100 tons displacement. Most Tenders and their Riders are currently deployed in the Hunter role, often to interdict strategic gas giants in or near the Regency frontier to stem unauthorised refueling, or to ambush Vampire fleets.
TB: Battle Tender. Minimum 100,000 tons displacement. Ship designed to carry line ships in excess of 10,000 tons displacement. Most Regency ships have a minimum J-4, 200,000 to 400,000 tons displacement, and carry 3 to 5 20,000 to 30,000 ton Battle Riders.
TS: Strike Tender. Smaller (<100,000 Tons) ship designed to carry smaller 500 to 10,000 ton riders into battle. Most common Tender in the Marches prior to the Fifth Frontier War. Unlike TB, TS is often designed to act in support of its carried task force.
V. CARRIERS. Military craft designed to carry, support armed small craft that constitute a major part of its function and firepower. Since this definition covers a good deal of ground, it includes so called "demi-carriers", cruisers and destroyers converted to carrying a large number of fighters and small SDBs. Most carriers, unlike Tenders above, carry substantial firepower and armor for self-defense.
VC: Cruiser Carrier. Cruiser converted to carry a large force of small craft. This includes many older Azhanti High Lightning class ships.
VD: Destroyer Carrier. Also known as a Pocket or Demi-Carrier. A 5000+ ton destroyer converted to carrying several fighters.
VF: Fleet Carrier. Carrier of more than 100,000 tons.
VS: Strike Carrier. Carrier of less than 100,000 tons. Both the VF and VS have been downgraded since the Regency has adopted the Zhodani method of building smaller multipurpose carriers based upon cruiser and destroyer hulls.
