The Sith-class Star Destroyer was designed to become the primary capital warship of the Sith Navy. A product of state-of-the-art technology and design techniques, the Sith Destroyer (abbreviated as SESD) is among the most nimble heavy warships in the galaxy. Its high-output engines afford it a high top-speed, and its overlapping shield grid give it deflector shielding comparable to the larger and better armed Imperial Mark II & III Star Destroyers employed by the Galactic Empire.
