HC-1 hypercannon

The HC-1 was a Republic superweapon designed to fire hypermissiles with a range of over 300 light-years. While the HC-1 was a Republic design, the plans to the cannon was captured by a Separatist agent at a Republic orbital research facility in orbit of Eriadu. The Separatists used the plans to construct their own HC-1, which was used to destroy at least two Republic Star Destroyers from several sectors away from Abrion Major before it was sabotaged by a squad of clone commandos.
