In spacecraft classification, a warship or war vessel is a generic term for any armed starship designed for combat. These vessels include battleships, battle cruisers, various sized cruisers, escorts, and destroyers.

Star Fleet had a habit of avoiding the use of warship classification, instead applying euphemisms such as "escort" and "tactical cruiser" for the Defiant-class and Prometheus-class, respectively. However as the needs of the fleet have changed, so to have Star Fleet's naming conventions.
