A corvette is a class of spacecraft denoted for their high speed and low size. Typically manned by a crew between 8 to 15 individuals, corvettes are typically used for a variety of purposes. Corvettes are typically used as pickets, escorts, swarmers, screeners, transports, support ships, and play an important role in guerilla warfare, being a favorite vessel for smaller factions and private militaries for their high speeds and low cost. A good corvette can quickly strike at an enemy position and swiftly flee, though the vessel's small size means that it cannot handle larger armaments or take significant damage without risk of destruction

Notable corvette classes include:

• Crustacean Class, a reconnaissance ship used by navies of Bletcher's League as well as the Milnilchlanese. It is still in use today.

• Velocity Class, the closest thing the Ibixan Empire got to a standardized ship class. Velocity-Class corvettes cost almost nothing to produce, but were very unreliable and prone to malfunction. Similar designs are in use by bandit and marauder groups, but the last Velocity-Class corvette was said to be destroyed in a hangar fire.

• Hagbeadi transport units may be considered corvette analogs.

Destroyers are medium sized spacecraft primarily used to lay and direct space mines, autonomous jell drives rigged with bombs that rapidly strike enemy ships upon detection by entering jell and re-emerging at the enemy's position. Space mines detect ships with Pylons that intercept enemy communication lines and their location relative to the time of detection. Apart from mine-laying, destroyers also act as screen ships and as escorts, being able to wield larger weaponry than a corvette. 

Notable destroyer classes include:

• Minelayer Class, a Clementinan creation used to do just that.

• Oberyon Class, a Neopolian screen ship used by pre-civil war roidocracies to deploy space mines and protect assets.

Cruisers are large vessels typically on the frontlines of space combat, with crews in the hundreds and devastating weaponry equipped for combat against other cruisers or smaller ships. Missile swarm launchers, anti-hull cannons, and ultra-high frequency lasers may be based on crusiers. Cruisers may also contain hangars from where space superiority or strike craft may take off or land at. While not necessarily intended, cruisers may hold auxillary fuel for other craft to use in non-combat situations, or transport large goods if needed. Cruisers tend to be slower and bulkier than smaller ships due to large size and an increased power priority to the ship's many features rather than the engines.

Notable cruiser classes include:

• Clagg Class, a cruiser class used by the Clementinan Space Navy. Opted for travel over extremely long distances, the Clagg was used extensively in the Gap Campaign as well as in the Grimlands. However, the Clagg was vulnerable to swarm tactics due to its heavy weaponry, which were devastating but had a slow rate of fire.

• Veric Class, a cruiser class used by the Kyrnomacek Space Navy to hunt Blossom cells in asteroid belts, firing cannons to move or split asteroids as needed.

Battleships are massive vessels manned by thousands and capable of holding most devastating weaponry. Battleships act as flagships for navies, using heavy weaponry to demolish the hulls of enemy ships of just about any size. Certain battleship classes also act as carriers for smaller craft, which can include military strike craft and even corvettes. These floating cities are often escorted by cruisers and destroyers, as although extremely powerful, battleships were notoriously notable for attracting space mines that would need to be repelled by anti-mines or cannon fodder ships.

Notable battleship classes include:

• Massivicus Class, a battleship class used by the Kyrnomacek Space Navy to act as a fire distraction for enemy ships while escorts could pick off enemy forces. Due to being under heavy fire, Massivicus Class battleships required some of the largest hulls ever deployed.

• Titan Class, a battleship class used by Calor to glass the surface of bodies holding enemy strongholds. The vast array of missiles and radiation cannons on the ship could render a planet's surface uninhabitable in minutes.

Artillery ships are more or less colossial guns that require their own hulls to transport on. Although not crewed by as many individuals as a battleship, an artillery ship can obliterate whatever is unfortunate enough to be in its line of fire. The most common usage of artillery ships is to act as a hard counter to battleships, propelling a superlaser or asteroids at a target with unprecedented force. Artillery ships can crack small planets depending on the armaments used on-board, but are especially vulnerable to large numbers of enemy ships and require great protection.

Notable artillery classes include:

• Colossus Class, a superlaser attached to a spinal mount and typically used to strike at enemy battleships or fortress worlds. Used by both the Kyrnomacek Space Navy and the Clementinans, Colossi can crack planets in synchronized barrages.

• Apollyon Class, an elusive class of ship originating in Thresher hands. Considered to be the largest non-celestial battlestation ship to ever be deployed, only a few were ever made, most of which were captured by the Hagbeadi during a battle in south Neopolis. The exact design is unknown, but it is known that the purpose of the Apollyon-Class cannon is to force a star to undergo supernova by piercing the convection zone and destabilizing the core.

Subspace ships are sleek spacecraft that blend in directly with empty space by tricking scanners into detecting nothing or a mundane object. Subspace ships therefore act as stealth ships and can sneak through an armada or a space minefield undetected, leaving it open to gather intel or fire space torpedoes at unsuspecting battleships. Chameleon plating and thermal controls prevent subspace ships from being detected visually. The devices used by subspace ships to remain undetected can be prone to overloading unfortunately, and must occasionally take time at reduced usage to recalibrate, leaving the subspace ship potentially vulnerable. Typically, larger subspace ships require more off-time, therefore subspace ships tend to be corvette-sized. 

Notable subspace classes include:

• Yu-Class, the class of subspace ship used by the infamous Raumkrieg Corps, known for their hit-and-run wolfpack tactics in space combat. The Yu-Class subspace ship is considered to be an icon of unrestricted subspace ship warfare.
