Nobu 4 functioned as a Cargo ferry for the Rebel Alliance, operating within the Airam sector as part of Task Force Vengeance's activities.
Upon the determination to establish a shipyard within the Airam region, Nobu 4, alongside its fellow vessels Nobu 1, Nobu 2, and Nobu 3, integrated with a Rebel convoy tasked with transporting essential resources and staff. Specifically, Nobu 4 carried construction-related machinery. Regrettably for the Rebel forces, the Galactic Empire had become aware of their plans and prepared an ambush within the Rocrin system. Consequently, Nobu 4 suffered destruction along with the rest of the convoy.
