The Secutor-class Star Destroyer, also known as the Secutor-class battlecruiser, was a carrier in the Imperial Navy.
The Secutor-class was 2.2 kilometers long and had two ventral hangar apertures, serving primarily as a carrier. Its length and volume would normally have put it in the battlecruiser-scale of the Anaxes War College System, specifically under Star Cruiser, and it was even given the alternate designation of Secutor-class battlecruiser because of this, but it was lightly armed for its size and had extensive carrier-capability and was instead designated as a Star Destroyer. The carrier was one of the largest dedicated craft in the Navy. This Star Destroyer class had several gun batteries lining the dorsal superstructure, on a diagonal ridge in front of the command tower. They carried 144 TIE series starfighters, other craft, and enough military forces to subjugate a planet. The Secutor-class was designed with a double command tower, in a style reminiscent of the contemporary Venator-class Star Destroyer. Unlike other Imperial Navy Star Destroyers, the bridge was mounted amidships instead of over the ion drives.
The Secutor-class Star Destroyer was designed early in Imperial history as evidenced by the common design elements it shared with the Venator-class Star Destroyer, which was itself designed and built near the beginning of the Clone Wars. It stemmed from a battlecruiser design from the Republic.
Several ships of this class were serviced at Naval Station Validusia. During the Galactic Civil War, the Secutors were relatively rare, although they often appeared when least expected with their battlegroup to attack Rebel bases or support other battlegroups. At least one Secutor-class Star Destroyer entered a conflict with a Providence-class carrier/destroyer and a Quasar Fire-class bulk cruiser.
In 10 ABY, at least one vessel of this class was part of the fleet orbiting Byss when Luke Skywalker was brought to the planet to face the then-resurrected Emperor Palpatine.
