Battle of Antarctica

This battle took place in the air above the continent of Antarctica on Earth between humans, using X-302 fighters and the USS Prometheus (X-303), and the forces of Anubis.

While the initial reason for the battle was the invasion of Earth, it evolved into Anubis trying to stop SG-1 from gaining entrance to the outpost left by the Ancients.

In the end, Colonel Jack O'Neill was able to access the outpost's defensive system and use Ancient drones to destroy Anubis's fleet.
