On that note, what the heck is a battlestar supposed to be?![]()
The Colonials had battlestars, the Cylons had base stars. In that universe, it was the term for the largest class of warships, the carriers and command platforms. Same logic as "Death Star," come to think of it, though probably arrived at independently. Larson wanted the terminology to sound exotic and alien, and probably somewhat mythological.
Another nomenclatural oddity in Galactica is using "Colonies" in the name of a sovereign nation. But they seemed to base their cultural identity on their origin as colonies of Kobol, so I guess they kept the name for sentimental reasons.
