The Malevolence's ion sphere generated by the pulse cannon.
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]
The SeparatistflagshipMalevolence 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]
