Tanith's Ha'tak

Tanith's Ha'tak was a ha'tak modified by the Goa'uld Anubis to posses Ancient shield technology. Taken to Tollana, the ha'tak managed to resist the blasts from a Tollan ion cannon. Tanith used the shielding technology to force the Curia to make phase weapons that would pierce any solid manner, including the Iris used by the Stargate on Earth. However, Narim destroyed the weapons, causing Tanith to use the ha'tak to devastate Tollana.
