A Battle Dreadnought class, or simply a Battle Dreadnought, was a type of warship classification used by the Chiss Ascendancy that was given to alien starships that were slightly smaller than a Chiss Nightdragon man-of-war or half as larger. The Nikardun Battle Dreadnought was a class of warship of the designation. Another Battle Dreadnought, the HopeBreaker, was used against the Chiss by the Grysk warlike species.
