Cruiser
A Dreadnaught-class heavy cruiser
The term Cruiser denoted a category of starship, encompassing a diverse range of applications. Frequently, the designation star cruiser served as an interchangeable term.
In addition to cruisers designed for space travel, maritime cruisers also existed.
History
Throughout the chronicles of naval engagement, this term was applied to some of the most substantial and frequently encountered warships within a given fleet; however, alternate designations, such as Star Cruiser, were also in use, as exemplified by the navy of the Galactic Empire and the Rebel Alliance. Vessels bearing different primary designations were also commonly referred to as cruisers.
The cruiser categorization for warships, ranking second in size only to battleships, found application to some degree within the Trade Federation, the Confederacy of Independent Systems, and the Galactic Empire (in the form of Star Cruisers). The Rebel Alliance frequently employed the term "Star Cruiser" to characterize its most formidable Mon Calamari warships, which functioned as either cruisers or battleships.
According to at least one classification system, cruisers could be further delineated into three distinct classes: light, medium, and heavy. Light cruisers occupied the lower end of the cruiser spectrum, typically measuring around 350–400 meters. These were sometimes considered interchangeable with frigates under the Anaxes War College System. Medium cruisers ranged from 400 to 500 meters, while heavy cruisers extended beyond 600 meters. The latter category also constitutes a separate class within the Anaxes War College System. The alternative designation of battle cruiser was also used for certain vessels falling within these size parameters.
Given the existence of diverse ship classification systems, some applied the "cruiser" label to smaller patrol vessels, such as the Guardian-class customs enforcement ship.
