This Ha'tak vessel looked like all other known Ha'taks. Since it served as the mothership of a powerful System Lord, it is possible that it is superior to standard Ha'tak vessels but this has never been proven.
Two of Heru´Ur´s Ha´Taks were sent to pursuit Klorel that scaped to Tollana, where Klorel knows the Heru´Ur Ha´Taks would be destroyed by the superior Tollan Technology.
Heru'ur's Ha'tak was the personal mothership of Heru'ur, which he used during a meeting with Apophis to discuss an alliance. Before this event, Teal'c was captured on Chulak by Jaffa loyal to Heru'ur and brought upon his ship to be tortured by Terok before planning to send him to Apophis as part of a deal with him. However the Tok'ra got information about the meeting and tried to stage a war between the two System Lords. This mission was conducted by Jacob Carter together with SG-1. When Teal'c was presented to Apophis and meant to be sent to him, SG-1 tried to intercept the matter stream between the two ships to retrieve Teal'c, but failed. Luckily for them, Teal'c convinced a Jaffa named Rak'nor to help him and only Terak was sent over. With the sabotage and Teal'c not being sent over, Apophis believed that he had been betrayed and attacked Heru'ur's Hat'ak, revealing he had a cloaked fleet in the minefield. Using the superior firepower of his mothership, Apophis easily destroyed Heru'ur's ship, thus killing Heru'ur. With Heru'ur's death, Apophis absorbed his forces into his own and became more powerful than ever which unfortunately was the opposite result of what SG-1 and the Tok'ra had been hoping for.
