Progenitor weapons. There were two types of them, the Sajuuk Main Cannon and the standard Phased Cannon Array mounted on both Progenitor Dreadnaughts. Due to the enormous amount of energy required and heat produced, both of these required the ship to be built around the weapon itself, much like Ion Cannon frigates. These mighty weapons required some time and a considerable amount of power to charge, but were devastatingly effective. They could destroy even a Super Capital Ship in a few hits and had an exceedingly long range.Phased Cannon Arrays were powerful
The exact mechanism of these cannons is unknown, as is demonstrated by the destruction of the Hiigaran Dreadnaught's cannon when it was first fired. The Bentusi possess knowledge of the cannons' workings, and were able to repair the Hiigaran Dreadnaught's Great Cannon.
