Nirrti's Ha'tak is one of the Ha'tak's that belonged to Nirrti before her banishment.


Nirrti used this Ha'tak to send an Engineered Virus into the atmosphere of the planet Hanka and kill the Hankans and SG-7. The Ha'tak was later spotted by Colonel Jack O'Neill and Teal'c when they were using the Douglas Mclean Memorial Observatory to photograph a Black hole. The Ha'tak sent out Death Gliders that chased the two through the Stargate. (SG1: "Singularity")
