Cruiser was a fairly generic term for a type of military space ship. Other terms used in the Vorkosigan Saga for these ships included war cruisers, battle cruisers, light cruisers, and fast cruisers.
- There were General-class cruisers in the Barrayaran service: the two named examples were the General Vorhartung and the General Vorkraft. These had more power than speed, and crews of about 150. 
- The Ariel in the Dendarii Free Mercenary Fleet was identified variously as a light cruiser and as a fast cruiser; it had much more speed than power. It had a crew of twenty, which was rather less than some of the other ships in the fleet.   
- Cetagandan Imperial Security used Imperial battle cruisers when such were needed.
