Interdictor-class Star Destroyer

The Interdictor-class Star Destroyer was a Star Destroyer used by the Galactic Empire that was capable of emitting an interdiction field to pull passing ships out of hyperspace. It was used against the rebellion around 4 BBY.

History
A prototype Interdictor-class was tested in the Del Zennis system in 4 BBY, under the command of Admiral Brom Titus. After pulling the Rebel ship Liberator out of hyperspace, the crew was imprisoned. However, they escaped and sabotaged the ship, destroying it in the process of their escape.

Two were later used by Grand Admiral Thrawn's Seventh Fleet during its assault on Atollon. However, one under the command of Admiral Kassius Konstantine was drawn out of position by an approaching rebel Quasar Fire-class cruiser-carrier. The carrier deliberately collided with the interdictor to allow other rebels to escape. The other was later destroyed by several mandalorians.
