Nobu 4 was a Rebel Alliance Cargo ferry which served in the Airam sector during the operations of Task Force Vengeance.

When the decision was made to construct a shipyard in Airam space, Nobu 4 and its sister-ships, Nobu 1, Nobu 2, and Nobu 3, were joined with a Rebel convoy charged with bringing the needed supplies and personnel. Nobu 4 itself bore construction equipment. Unfortunately for the Rebels, the Galactic Empire had learned of them and readied a trap in the Rocrin system. Nobu 4 was destroyed with all the others.
