A cruiser was a designation given to starships, usually capital ships, of varying sizes and capabilities. While usually considered to be reserved for ships around 400-600 meters in size, the term sometimes included corvettes and frigates alongside 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". The Kilji species' government of the Kilji Illumine used Kilji war cruisers and Kilji picket cruisers.
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 such as the Delta-7 Aethersprite-class light interceptor.
