Hydra was a Ton-Falk-class escort carrier that was part of Task Force Vengeance. The ship was part of a major convoy escorting various freighters. The fleet was then inspected by A-wings from Rogue Squadron that was tasked to inspect all Imperial ships and to destroy any freighters carrying Warheads to guage the strength and to buy time to muster their forces. The A-wings managed to achieve their objectives despite many of the ships, the Hydra included, launching TIE Fighters and Interceptors to intercept the A-wings.
