Anubis' mothership was a new class of Goa'uld vessel, in service around the Battle of Harakesh to the Endor War, designed to serve as the flagship of the Goa'uld Anubis. Two such vessels are known to have existed, with the second one having served as a replacement after the destruction of the first. Superior in both size and power to any other Goa'uld vessel previously constructed, and constructed using a combination of Goa'uld and Ancient technology, this ship far surpassed the Ha'tak-class vessels utilized by the other Goa'uld System Lords, in part aiding in Anubis' efforts to conquer the galaxy.
