The Eclipse Star Destroyer had a canon that equaled the power of the Deathstar. It was basically used to destroy other capital ships and space stations. Furthermore, it had the capacity to blow through a planet’s shields and obliterate it. The Eclipse-class Super Star Destroyer could also destroy other Super Star Destroyers effortlessly.
