Apophis' mothership

Apophis' mothership was his flagship. First seen after Apophis took control of Sokar's forces, the vessel possessed many advantages over the standard ha'tak: it was larger, possessed a faster hyperdrive, and had weapons which could destroy a fully functioning ha'tak easily. Apophis took the ship to his meeting with Heru'ur, and destroyed Heru'ur's flagship with just a few shots. Apophis also took it to Vorash, in an attempt to destroy the Tok'ra. The supernova of Vorash's sun sent Apophis' mothership into another galaxy, along with SG-1. While there, the vessel was boarded by Replicators, who overran the ship. Apophis set the self-destruct, and escaped. The Replicators were unable to deactivate the self-destruct, and the ship was destroyed.
