- SG-1 and the Giza Stargate were transported aboard Thor's vessel (Biliskner), when it was over taken by Replicators. SG1 attached an elementary naquadah enhanced bomb (BF-8) on the deceleration drive, which was detonated when the vessel entered Earth's atmosphere. Thor's vessel crashed into the Pacific Ocean, but a single Replicators survived and quickly overtook a Russian submarine. Fortunately, the submarine was destroyed before the replicator infestation escaped. However the Gaza Stargate, used by SG-1 to escape Thor's vessels, was lost in the Pacific Ocean. In response, Genrald Hammond ordered that the Antarctic Stargate to be brought out of storage, and used to replace the Giza Stargate.
