49AX3 functioned within the Galactic Empire's navy as a Dreadnought-class heavy cruiser. The Alliance to Restore the Republic seized the vessel sometime between 3 and 4 ABY. Subsequently, they utilized it in a raid targeting Imperial Refining Platform M36, a refining facility situated in the Outer Rim Territories. Luke Skywalker aided the rebel group, who successfully steal fuel from the refinery. However, their departure was hindered by an Imperial-class Star Destroyer. Skywalker piloted his X-wing into the hangar of the Star Destroyer. There, he and the rebel major employed a shuttle as a diversion, successfully luring the Imperial TIE fighters. This strategy proved effective, allowing the rebels on 49AX3 to timely escape to a planet in close proximity.
