Subjugator functioned as an Imperial II-class Star Destroyer while serving the Galactic Empire.
Alongside the Restrainer, an Immobilizer 418 cruiser, it engaged in an attempt to waylay the Rebel frigate Redemption, which was carrying Commander Zaletta, an Imperial defector.
Regrettably, the element of surprise was lost due to the actions of Ace Azzameen, a Rebel pilot, who was aided by the Alliance cruiser Liberty. Both the Interdictor and the Star Destroyer were obliterated.
