During the Galactic Civil War, the EF76 Nebulon-B escort frigate Akaga served the Imperial forces, specifically under the command of Admiral Harkov.
Following the Battle of Hoth, Admiral Harkov turned against the Empire, and the Akaga abandoned the Imperial Navy, joining the Alliance to Restore the Republic. Subsequently, Lord Vader located Harkov's fleet within the Ottega system tracked, dispatching the Interdictor Harpax to ensnare the Admiral's former flagship, the Protector. This action spurred a desperate counterattack from the Akaga along with the Rebel Calamari Cruiser Warhawk. The Akaga gave chase to the Harpax, seeking to eliminate it, but was met with resistance from Imperial starfighters commanded by Tan Maarek Stele, ultimately leading to its destruction.
