Autokrator: An Imperial Star Destroyer larger and more heavily armed than the more common Imperator and Tector-class Star Destroyers.

Defensor: The Defensor-class is a type of battleship in use by the Imperial Navy. Apart from its length (12.8 km) and its description as a Star Destroyer, little is known about it. The HIMS Ulic Qel-Droma was a ship of this class, named personally by Emperor Palpatine. Due to its status as a Star Destroyer and its High Galactic name, the Defensor-class is presumed to be a Star Cruiser of KDY make.

Lictor: The Lictor-class Dungeon Ship was, appropriately enough, a flying oubliette in use by the Inquisition for the capture and incarceration of Force magi. It's assumed to be a KDY design with a displacement on par with other prison ships, but this is purely speculation.
