A more advanced Goa'uld battleship. Several times larger in size than an ordinary Ha'tak class vessel. The ship is thought to have been stolen from Sokar when he took over his army.
The ship has superior fire power and more powerful shields. It can destroy a Ha'tak class vessel in a few shots. The weapons are also able to penetrate a Goa'uld Mothership's shields, even if they are at full power.
The ship was destroyed soon after SG1 destroyed Apophis' fleet. After loosing to the Replicators, Apophis set his ship to self-destruct and escaped.
