Imperius-class super dreadnought

The Imperius-class super dreadnought was an 300 km-long star destroyer type used by the mysterious Eternal Imperium, based in the Unknown Regions. This ship was similar to an Imperial Executor-class dreadnought, but, as mentioned above, was much, much bigger. With a superlaser mount on one of its ventral fins, capable of destroying a planet, this star destroyer was the bane of the Galactic Alliance's Naval forces.
