Geonosian dreadnaught

The Geonosian Dreadnaught was a Separatist warship, manufactured or used by the Geonosian faction of the Confederacy of Independent Systems.

It had a core ship-section that was said to be the size of a Dreadnaught-class heavy cruiser. It's diameter would be about 600 m, about 100 m smaller than Lucrehulk-class Core Ships. Whether or not this sphere constituted the whole of the vessel or could be connected to something larger, is unknown.

Behind the Scenes


The term "Geonosian Dreadnaught" is used in a single scene in the novelization of Revenge of the Sith. Here, General Grievous is standing in his control center on the planet Utapau, which is situated inside a spherical ship dug into the side of a sinkhole, watching the Separatist Council head across the landing deck to board a starship for Mustafar.

Depending on how the passage is read, the Geonosian Dreadnaught could be:
 * The headquarters itself, which is later described from Obi-Wan Kenobi's point of view as "a spiny spheroid of metal: a Dreadnaught-sized structure".
 * Another spherical capital ship that has come down into the sinkhole and parked alongside the lip of the hangar bay to take the Separatist leaders to their new stronghold on Mustafar.

The latter is improbable, as no such spherical structure is seen anywhere near the headquarters in any of the scenes in the movie. Several wide panorama-shots show the city stretching downwards into the sinkhole, with only one sphere at the tenth level.

In either case, it is unclear whether the Geonosian Dreadnaught constitutes a sphere the size of a Dreadnaught-class heavy cruiser or a larger ship, which the sphere-section would be a part of. As other core ships have been seen to function independently of larger vessels, this dreadnaught could very well be a spherical battleship in the Confederate Navy.
