The following classes of battlestar are deployed during the conflict:
- Artemis-class, the light battlestar from which all other battlestar classes are based. This model was used earlier in the war, but was quickly outmoded.
- Jupiter-class, commissioned during the Articles of Colonization, wherein each colony had its own battlestar. e.g. Galactica is Caprica's battlestar.
- Minerva-class, a heavy battlestar.
