The Earth variant Ha'tak-class mothership is a modified Ha'tak-class mothership made by modifying a mothership from Cronus and a mothership from Anubis using Earth and Sectoid technology to enhance the design. The only ships of this class are the Enterprise and the Admiral Kuznetsov. In March 2004, the Enterprise was destroyed during the Battle of Antarctica, however the crew did manage to escape the ship. After helping the Asgard, the Prometheus, Atlas, and Admiral Kuznetsov were refitted with Asgard technology.
