Planetary ion cannon

A '''planetary ion cannon was a massive blaster weapon that could be used to temporarily or permamently disable electrical systems and penetrate shields. Its power source was usually a dedicated reactor sunken into the ground and it could be erected in several hours. One is seen on the planet of Hoth during the Battle of Hoth. The ion cannon fired at an Imperial Star Destroyer leaving it un-operational, thus letting some Rebel Escort Frigates escape the planet before the Imperial invasion underwent.

Kuat Drive Yards was a large producer of planetary ion cannons.
