The Secutor-class Star Destroyer, also known as the Secutor-class battlecarrier, was a type of Star Destroyer, carrier, and battlecruiser used by the Galactic Empire. Dating from early in the Imperial Era, the multi-kilometer Secutor was possibly the largest dedicated starfighter carrier in the Imperial Navy. Heavily armed with turbolasers, ion cannons, and tractor beams, the Star Destroyer also carried tens of thousands of personnel, as well as two wings of starfighters, walkers, and other armored fighting vehicles, allowing it to easily lay siege to a planet.

The Secutor-class was commonly used as a command ship or flagship in charge of a task force, often encountered during offensive operations against Rebel Alliance fleets, strongholds, and rebellious worlds. Alternatively, the Star Destroyer could also be used as an escort to larger Star Dreadnoughts. One particular Secutor-class Star Destroyer was the Conquest, which was commanded by Naval Intelligence Agency Vice Admiral Dodd Rancit, who used the ship to lead a flotilla above Carida in 14 BBY. However, he was later outed as a traitor to the Empire and killed by his own crew.
