Battlestar Galactica (fictional spacecraft)

Battlestar Galactica is a fictional space battleship based in the science fiction television series of the same name. In the original 1978 series, it was implied there were 12 Battlestars, one for each of the Twelve Colonies. However, in the reimagined series from 2003, the colonial fleet had about 120 Battlestars by the time of the Cylons' surprise attack on the colonies. The Cylons also have large battleships that are known as Basestars.
