Rutan Mothership

Rutan Motherships were the spaceships of the Rutan Battlefleet. They had crystalline structures and anti-gravity systems. From afar, they appeared to resemble dim, yellowish fireballs. Motherships had enough firepower to reduce islands to molten rock.

Rutan Scouts landed on a planet and established a beacon for the ship. Should this fail, the Mothership could still find the scout if it received the signal long enough. (TV: Horror of Fang Rock)
