A planetary ion cannon was a massive ion weapon that could be used to temporarily or permanently disable electrical systems and penetrate shields. Used mainly in defense, they were also used by pirates on anarchic worlds such as Lok to disable ships for looting. Its power source was usually a dedicated reactor sunken into the ground and it could be erected in several hours. Two planetary ion cannons of an unknown model were present during the Battle of Artus Prime during the Empire Reborn Crisis. Kuat Drive Yards was a large producer of planetary ion cannons.
