AX-235 was a Rebel listening post hidden in the asteroids of Cron Drift to monitor Imperial transmissions detected by some communications satellites, stolen from Orron III. It was the very outpost that intercepted an Imperial transmission with the schematics of the Death Star. Due to the importance of what had been discovered, Biggs Darklighter was sent to personally courier the schematics out of AX-235, taking them to the Mon Calamari Star Cruiser Independence.
The scenario of X-wing is inconsistent with the canonical history (including the A New Hope opening crawl), according to which the plans were taken during the Battle of Toprawa. The plans carried to Tantive IV by Biggs in a later mission of the game are not a result of the battle, but are implied to be the same ones tapped by the outpost.
The image of the outpost's control room is based on Ralph McQuarrie's concept art for the Echo Base ion cannon control room for Star Wars: Episode V The Empire Strikes Back.
