Advanced Ha'tak variant
- "If Apophis is allowed to complete this battleship, it will assure his dominance over the Goa'uld, [Earth], and the rest of this galaxy."
Developed on the surface of PX9-757, the vessel carried several advancements that surpassed the standard Goa'uld Ha'tak-class ship encountered previously by Stargate Command. According to both Teal'c and Anise, these advancements were so great they would've given Apophis great superiority over all the other System Lords. The power core of the ship was sealed entirely in Trinium and was linked to a liquid cooling system that stemmed in all directions into the mountainside of the construction facility. This zone was protected by Goa'uld forcefields and Jaffa patrols. (SG1: "Upgrades")
An attempt at sabotage by the Tok'ra during the ship's construction failed. However, when the Tok'ra Anise supplied SG-1 members Colonel Jack O'Neill, Major Samantha Carter and Dr. Daniel Jackson with Atanik armbands, the team disobeyed orders, traveled to PX9-757, and successfully destroyed the ship by destroying the engine cooling systems with C-4.
