Omicron 1 was a DX-9 stormtrooper transport of the Delta-class. It carried Imperial officers who were on assignment to the Death Star. Alliance Special Forces conducted a sabotage operation, which resulted in the transport becoming stranded within the Corellian system. Subsequently, the Alliance dispatched a team to capture the vessel. This team included Y-wings from Red Squadron, with Keyan Farlander as one of the pilots, and X-wings from Blue Squadron, along with a Lambda-class shuttle named Hunter. Their mission was to board the transport, seize control, and deliver it to the EF76 Nebulon-B escort frigate Inad. Almost immediately after the shuttle boarded the transport, Assault Gunboats appeared, attempting an interception. Rebel fighters engaged and successfully destroyed the gunboats, though some losses were sustained. After the transport's capture, as the Inad moved to retrieve it, the Imperial-class Star Destroyer Immortal arrived on the scene. The Immortal launched TIE Fighters and Bombers, and three additional transports moved to recapture the captured transport. However, Farlander, piloting his Y-wing, successfully defended against the attacking forces, enabling the transport to board the frigate. The frigate then jumped to Hyperspace.
