The ion pulse cannon was a massive experimental ion cannon model fitted onto the Subjugator-class heavy cruiser Malevolence.


"A weapon that neutralizes all power to our ships, rendering the targets defenseless."
―Plo Koon[src]

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.[1] After each shot, the technicians had to allot some time to clean up residual ionized particles in the cannon before firing again.[3]

Unfortunately, the cannons took their tolls on the Malevolence as well. The sheer power of the cannons was very difficult to control; after firing the weapons, some of their energy would leak back into the cruiser, temporarily depowering on-board systems in the process.[4]


"We tracked the mystery weapon to this system. That is when we found out it was an ion cannon"
―Plo Koon[src]

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.[3]
