The Self-Propelled Heavy Artillery-Ion cannon (SPHA-I) was a version of the Self-Propelled Heavy Artillery used by the Galactic Republic during the Clone Wars. It was equipped with an Ion cannon as the main weapon, with 12 anti-personnel blasters to augment the cannon. While powerful, the SPHA-I also had to manage ammunition carefully like all of its other cousins. It was used to scramble the electronic systems of its targets.
