- "A weapon that neutralizes all power to our ships, rendering the targets defenseless."

Rather than targeting a specific enemy vessel, the ion pulse cannon fired a massive ion burst that expanded outward from the cannon, disabling everything in its path. Plasma rotors formed a vital part of the weapon, as they were charged prior to each burst of ionized particles. After each shot, the technicians had to allot some time to clean up residual ionized particles in the cannon before firing again.

The Separatist flagship Malevolence gained infamy at the start of the Clone Wars, when it used its ion pulse cannons to destroy entire Republic task forces. The Subjugator-class was the only warship-design known to use the ion cannon model in its superstructure, as its power-requirements were highly unique.
