Nobu 3 functioned as a Cargo ferry for the Rebel Alliance, operating within the Airam sector while Task Force Vengeance conducted its missions.
The decision to establish a shipyard within the Airam sector led to Nobu 3, along with its sister vessels, namely Nobu 1, Nobu 2, and Nobu 4, being integrated into a Rebel convoy. This convoy was tasked with transporting necessary materials and staff. Nobu 3's specific cargo consisted of construction machinery. Regrettably for the Rebel forces, the Galactic Empire had discovered their plans and set an ambush within the Rocrin system. Consequently, Nobu 3 met its end, along with the rest of the convoy.
