As part of the ship's interim repairs, "Liverpool" had a provisional false bow constructed and fitted. Once able to embark on a prolonged voyage, "Liverpool" steamed to the United States to have her bow reconstructed at Mare Island Naval Shipyard in Vallejo, California. The ship's presence would not be disclosed until September when the US Navy Department released a list identifying 12 ships situated in various ports. At the shipyard, "Liverpool" had her anti-aircraft armament increased with the addition of nine single 20 mm Oerlikon cannons. She departed in November for Britain, principally to have upgraded radar systems installed.
