On 3 May, the submarine received orders to return to Hawaii. She refueled at Saipan and continued on to Pearl Harbor where she arrived on 18 May. After 10 days of recreation and inspection of the boat, additional orders sent her back to the United States for overhaul at the Portsmouth Navy Yard. She stopped at San Francisco Naval Shipyard, then continued on through the Panama Canal and up the Atlantic coast to Portsmouth where she arrived on 22 June. The submarine was still undergoing overhaul when hostilities ended. Following completion of the overhaul, "Bang" operated out of New London in the early postwar period. She was placed out of commission on 12 February 1947 and entered the Atlantic Reserve Fleet.
