The Ranger was a YT-1300 freighter employed by the Airam.
During the time of the Galactic Civil War, Alliance forces captured the Interdictor named Compellor. Their goal was to equip one of their Strike-class medium cruiser ships, specifically the Peregrine, with Gravity well projectors at the Deep Space Manufacturing Facility known as Gallofree. Following the successful completion of this task, an Imperial force launched an assault on the facility after witnessing the destruction of the Compellor. In response, the Alliance dispatched X-wings from Rogue Squadron and B-wings from Green Squadron, along with 3 medium transports to evacuate personnel. During this conflict, the Ranger participated by offering support against the Imperial starfighters, which included TIE Avengers belonging to Avenger Squadron.
After the Imperials were successfully repelled, Clan leader Tamaron made arrangements to resupply the Rebels with Warheads at Kuras Drift. The Ranger was present when rival Airam forces, led by Ilay, attacked the Airam base there.
