The Thunder was a CR90 corvette of the Airam group, playing a role in the events of the Galactic Civil War.
In the course of the Battle of Nocto, the Airam dispatched the Corvette, carrying a full complement of Proton bombs, with the mission to collide with the bridge of the Star Dreadnought Vengeance. This objective was achieved, resulting in the total destruction of the bridge. Soon following this action, a group of B-Wing starfighters eliminated the Super Star Destroyer by disabling its shields.
