The star cruiser was a starship classification for the largest cruisers in Federation Starfleet in the early 25th century. Star cruisers were larger and held the largest crew complements of any other starship type in Starfleet, except for dreadnoughts. Star cruisers dwarfed heavy cruisers by a magnitude. Star cruisers acted as flagships and support for fleets.
The star cruisers were introduced in the early 25th century. This starship type consisted of individual ship classes. These were designed to be modular, allowing commanding officers to swap sections between ship classes, including the saucer section, secondary hull, nacelle pylons, and nacelles.
Star cruisers had a crew complement of 1,000 and access to four cruiser command abilities: strategic maneuvering, shield frequency modulation, weapon system efficiency and attract fire. These abilities allowed a star cruiser to improve maneuverability, deflector shield strength or weapon power; or to attract enemy fire to support weaker fleet ships.
Standard equipment was rated mark VII. Weapon systems included four phaser arrays and photon torpedo launchers each, four aft and fore each. The deflector array, shield array, impulse engine and matter anti-matter warp core were rated Mk VII. All of the equipment was replaceable.
Like all Federation starships of the early 25th century, all star cruisers had access to the Federation transwarp network. All star cruisers commanded by an officer ranked vice admiral or higher was equipped with quantum slipstream drive, and its shuttlecraft were equipped with Quantum slipstream drive, too. Star cruisers were capable of speeds in excess of warp factor 9.9. (STO video game: Welcome to Earth Spacedock)
