Ships of the class could carry hundreds of starfighters, as well as dozens of small support vessels, including frigate-sized ships. Its heavy armament was on par with the Empire's Executor Class Star Destroyer. The computers, electronic equipment, and sensor systems were above and beyond those of an Imperial Star Dreadnought, and it carried a HoloNet transceiver as well. The Viscount 's shields had backups, like previous Calamari designs, and were thus highly regenerative. The Viscount-class was equipped with over five thousand weapons systems, including heavy turbolaser batteries and assault concussion missile launchers. Dozens of docking clamps allowed the vessel to directly dock with many other capital ships at the same time. Its shape was also more compact than the Executor-class and it had heavier and more extensive armor. Furthermore, the vessel required a substantially smaller crew to operate. Although slightly shorter in length than the Executor-class, the superior engineering skills of the Mon Calamari enabled the vessel to carry more starfighters.
The first prototype was a 3 km long battlecruiser, and the full production model was a 17 km long dreadnought.
The Viscount-class Star Defender was envisioned as the New Republic equivalent of an Executor-class Star Dreadnought. Side and top profile of the Viscount-class with the bow to the left.
