The Interdictor-class Star Destroyer was a variant of the Imperial I-class Star Destroyer equipped with gravity well projectors.

Kuat Drive Yards decided to produce their own Interdictor offering to rival that of Sienar Fleet Systems by using an Imperial I-class Star Destroyer hull as a base. To make room for the gravity well projectors, half of the turbolasers and ion cannons, as well as eight of the Phylon Q7 tractor beam projectors found on the original Imperial-class Star Destroyer, had to be removed. The Interdictor-class Star Destroyer's reduced hangar held sixteen TIE fighters.
