Plasma cannons are the armament of protoss interceptors, replacing the pulse cannons used in the Great War. They are light cannons, allowing the interceptor to maintain maneuverability. The cannons can be controlled from the carrier, but can be fired by an interceptor's independent fire-control circuits (should they have them installed), which allow plasma cannons to continue firing even if the enemy jams the command signal or destroys the interceptor's robotic brain.[1]
