 Of the entire Colonial battle fleet, only the Battlestar "Galactica", a gigantic battleship and spacecraft carrier, appears to have survived the Cylon attack.Under the leadership of Commander Adama, the "Galactica" and the pilots of "Viper fighters" lead a fugitive fleet of survivors in search of the fabled thirteenth colony known as Earth.Glen A. Larson, the creator and executive producer of "Battlestar Galactica", claimed he had conceived of the "Battlestar Galactica" premise, which he called "Adam's Ark", during the late 1960s.
