Planetary ion cannon

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.
A V-150 was seen on the planet of Hoth during the Battle of Hoth. The ion cannon fired at—and hit—the Imperial-Star Destroyer Tyrant, which left it non-operational and allowed several Rebel medium transports escape the planet before the Imperial invasion commenced.
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, including the V-150.
