Space going WarShips are often classified with the following terms, based on their role. Most of these terms have survived since the Age of Sail, and were updated to reflect the realities of space combat. Because of the somewhat diffuse criteria associated with each class and role, the classification is arbitrary and ultimately rather subjective. It has no impact on gameplay.
(Another classification is the distinction between Small Warships and Large Warships, which only defines each by mass versus function. Strategic Operations (p.10 - Warship size/weight) divides ships built to WarShip specifications into either Large and Small Warships, with small WarShips defined as any vessel smaller than 570,000 tons. Unlike classification, the distinction between Large and Small WarShips does have certain effects under the game rules.)
WarShip classes are roughly defined thus:
- Corvettes - Typically the smallest WarShip category; the heaviest Corvette design masses 412,000 tons but seems to be an outlier, as no other designs masses more than 240,000 tons. Lightly armed and armored but swift and equipped for extended tours of duty, corvettes are ideal for commerce protection and raiding. They are not expected to stand up to other WarShips, except in a support role.
- Destroyers - Larger and more heavily armed than corvettes, these ships perform the same raiding and escort duties, but also serve as guardians of orbital installations. They typically mass between 500,000 and 700,000 tons.
- Frigates - Rarely smaller than 700,000 tons, these ships can roughly be described as extra-large destroyers, often adding an additional capacity over standard destroyers such as integral fighter support.
- Cruisers - The most diverse ship category in any fleet, vessels in this class are typically further subdivided into light cruisers, heavy cruisers, and battlecruisers. In the original sense of the word, cruisers were supposed to be more durable than smaller ship classes and capable of prolonged independent operation. Most cruisers pack enough equipment and supplies to operate away from technical support bases, making them ideal raiders. As a whole, cruisers typically mass between 700,000 and 1,200,000 tons.
- Light Cruisers - As their speed is comparable to destroyers and frigates they serve as escorts, raiders, and picket ships, but outperform the other two ship types in one or more areas (speed, firepower, armor and/or endurance).
- Heavy Cruisers - These ships tend to trade away some of the light cruiser's speed for additional firepower or armor. Clan toumans typically use these as command vessels.
- Battlecruisers - These large ships are designed to punch above their weight class, usually sacrificing armor and any other features. Often, speed (i.e. large and powerful thrust engines) is considered another defining factor, exacerbating the reduction in armor and secondary functions.
- Battleships - The largest regular ship class, battleships are easily able to keep pace with frigates and outrun heavy cruisers. Their massive weapon payloads and armor protection is achieved through sheer size, and consequently often are a poor match for smaller vessels ton-per-ton. They often serve as a fleet flagships, while hitting the most dangerous and determined opposition to break through and create opportunities for their smaller companions to exploit. The pride of the SLDF Navy, the McKenna-class battleship, weighed two million tons, a record that was not broken until Clan Ghost Bear launched the 2.4 million ton Leviathan-class ship.
- Dreadnoughts - Arguably a classification denoting the largest, most powerful and/or technically most advanced class(es) of WarShips. The word is often used to describe a cutting-edge ship class that can outfight any other contemporary WarShip. Typically, Dreadnoughts are very powerful but also very expensive and possibly inefficient, and are not deployed in any significant numbers.
Other "classes" or designations exist, such as "Troop Cruiser" or "Pursuit Cruiser", though they can usually be placed in one of the above classes. In addition, there are a number of monikers that arguably fall in between class and role definitions:
- ArcShips - A concept enacted by Clan Sea Fox, ArcShips are former WarShips that have been heavily modified and reconfigured (often by permanently attaching DropShips) to serve as city-sized mobile space habitats.
- CargoShips - Similar to the aforementioned ArcShips, CargoShips are geared more to cargo than habitation, but otherwise share the same charactersitics. In a similar vein, Transporters are technically WarShips but are designed as armed cargo carriers more than actual frontline combatants.
- Carriers - These are WarShip-sized aerospace fighter transports. Principally, there have been few ships dedicated to the carrier role; during the Star League era many navies used hybrid designs that combined the carrier role with another ship type. As a result, carrier tonnages have varied from frigate to battlecruiser size. These dual-role ships were not produced by most of the factions in 31st century during the brief resumption of WarShip production; the one exception was Clan Snow Raven, who produced the Conqueror-class Battlecruiser-Carriers in limited numbers.
- Surveillance Vessels - Small or very small vessels massing from 6,100 to 120,000 tons, these unique ships were not intended for combat but for intelligence even though built with military-grade technology. Lightly armed in comparison to other WarShips, these vessel are designed to blend into merchant traffic, posing as civilian vessels while carrying out observations. After they had become obsolete, a few such vessels were converted to Q-Ships. The larger Surveillance ships, especially after refit to Q-Ships, could arguably be considered Corvettes.
- Yardships - Yardships are mobile shipyards, typically used to repair vessels that cannot make it to a fixed shipyard under their own power (a broken Kearny-Fuchida drive must be reparied on-site, as it would inhibit the formation of a K-F field in the vicinity and thus cannot be carried through a jump by another jump-capable ship).

Transports & Auxiliary Vessels
(These vessels fall into the WarShip category for technical reasons, but are not intended to be used as combat vessels.)
- Bug-Eye - 6,100 ton surveillance vessel, introduced in 2620 by the Star League. No hardpoints, fighters or small craft. Lightly armed reconnaissance vessel small enough to blend in with DropShip traffic. All remaining ships joined the Exodus, but were mothballed by the Clans, who regard such tactics as dishonorable.

- Nightwing - 100,000 ton surveillance vessel, introduced in 2447 by the Terran Hegemony. No hardpoints, 4 small craft. Designed to resemble a civilian JumpShip, mounts advanced surveillance gear. Phased out in favor of the more modern Bug-Eye when its integral electronics suite became outdated and could not be reworked.
- Tracker - 120,000 ton surveillance vessel/corvette. Older companion of the Nightwing class, designed to resemble a normal JumpShip. 2 hardpoints, 4 small craft. Served as "Q-Ship" on anti-pirate missions in the periphery towards the end of its active service.
- Vigilant - 140,000 ton corvette; small patrol vessel, replaced by the Vincent class in 2432. Noted for being relatively well-armed but with limited detection capabilities and therefore often paired with Bonaventure-class corvettes in groups of two each. No hardpoints, 6 fighters and 4 small craft.
- Pinto - 160,000 ton corvette. Designed and built by the Rim Worlds Republic and introduced in 2502; with weak armour but strong firepower the Pinto became an escort and orbital bombardment ship.
