A cruiser was a designation given to a starship, mostly capital ship, of varying sizes and capabilities. In a wider sense the term included corvettes, frigates and actual cruisers. Examples included the Consular-class space cruiser, the CR90 corvette, the Arquitens-class light cruiser, the MC80 Star Cruiser, and the Venator-class Star Destroyer, often referred to as a "Republic attack cruiser."
By the time of the Separatist Crisis, the Jedi Order typically used the Republic's cruisers for its diplomatic missions across the galaxy. However, some tasks required less conspicuous and smaller starships like the Delta-7 Aethersprite-class light interceptor.
