During the era of the Galactic Civil War, the Claw functioned as an Immobilizer 418 cruiser within the ranks of the Imperial Navy.
The Claw engaged in an endeavor to obstruct Rebels who had secured the Death Star II plans from the armed freighter called Suprosa, preventing their arrival at Kothlis.
While the hyperdrive systems of the Rebels were being impeded, the Claw deployed its contingent of starfighter to confront the opposing task force. Nevertheless, even with reinforcements provided by the Victory I-class Star Destroyer known as the Hunter, the Rebels successfully forced the ship to retreat, enabling their escape to their planned destination.
