10 Most Powerful Weapons In The Stargate Universe

10. Ancient Satellite

When the people of Earth found Atlantis, they discovered a highly technological city that was uninhabited. This was due to the war between the Lanteans and the Wraith, which resulted in the city being submerged and abandoned, but it wasn't completely devoid of defenses — Atlantis still had Ancient satellites.

The Ancient weapons platforms were situated between the planet and moon at the Lagrange Point, and they packed a serious punch. The Ancient satellites were nearly as large as a Goa'uld Ha'tak-class starship, and one remained when the humans discovered it, though it was heavily damaged.

When the Wraith dispatched three Hive ships to the Lantean system, members of the Atlantis expedition attempted to make it work. Because its power requirements were considerably low, it could be powered via a single Naquadah generator. Unfortunately, it was damaged, so it only managed to destroy a single ship.

The remaining Hive ships managed to destroy the satellite before it could be repaired for another shot. Despite being destroyed, the ease at which it destroyed a massive Hive ship revealed just how powerful the Ancient satellites were. Had it been fully-powered, it would have easily taken out all three ships.
