Interdictor-class cruiser

The Interdictor-class cruiser, also known as the hyperspace interdiction cruiser and the Interdictor-class Sith Destroyer,[8] was among the most numerous capital ships seen in action with the Sith Navy during[2] and after the Jedi Civil War.

Characteristics
The Interdictor-class was 600 meters long and featured a hull that split into two structures, one dorsal and one ventral.[5] The ship was propelled by three main thrusters and four auxiliary thrusters, similar to the Imperial-class Star Destroyer. Each ship was commanded from a sternward tower.[2]

The Interdictor-class cruiser was armed with 5 medium Turbolaser cannon batteries, 6 light Point-defense laser cannon batteries, 3 Tractor beam batteries, and 4 Gravity well projectors.[6] The infamous Interdictor-class cruiser and Sith warship, the Leviathan was equipped with 20 Quad laser cannons, 4 Turbolaser cannons, 2 Ion cannons and a tractor beam projector.[5] Despite the timespan between designs, the Interdictor-class cruiser was comparable in power to an Imperial Victory II-class Star Destroyer with all the advantages of the Immobilizer 418 cruiser and served a role similar to that of the more modern Star Destroyer designs.
