ship. Rasher then swung hard right to launch two stern torpedoes. Both torpedoes hit and Noshiro Maru slowed to and reversed course. joined the wolfpack and scored hits on two of the surviving transports. Rasher counted sixteen detonations from the eighteen torpedoes fired on 18 August and five detonations for the six fired on 5 August. With all torpedoes expended, Rasher set course for Midway. Munson was called into a secret conference at Midway to compare his observations with decrypted Japanese message traffic. Postwar accounting verified Rasher had sunk the highest tonnage of any World War II U.S. submarine patrol to that date. That record would be exceeded only once, when sank the Japanese aircraft carrier Shinano three months later. Rasher proceeded to San Francisco via Hawaii for overhaul at Hunter's Point Naval Shipyard on 11 September. She was given a new 5-inch deck gun, ST radar, and many other upgrades. Sixth, seventh, and eighth war patrols, January – August 1945 Benjamin Ernest Adams Jr. replaced Munson for the sixth war patrol. Rasher departed San Francisco on 20 December 1944, arriving at Midway via Pearl Harbor in early January 1945. Her sixth patrol, as a unit of a wolfpack with and , commenced on 29 January, and was conducted in the southern sector of the East China Sea. Rasher attacked a pair of ships on 15 February but missed, and approached a convoy the next day but was unable to get in position to attack. A later attack on another convoy also ended in misses. No other suitable targets were found, only small patrol craft, hospital ships, and ubiquitous patrol aircraft. The patrol ended on 16 March 1945 at Guam. Charles Derick Nace replaced Adams for the seventh and eighth patrols. Rasher's seventh patrol, 17 April to 29 May 1945, was little more rewarding than the sixth. On lifeguard station off Honshū, she riddled two small craft with gunfire. No aircraft came down in her area, and she returned to Midway on 29 May. Rasher departed Midway 23 June 1945 to take lifeguard station off southern Formosa. No Allied planes were downed in her area before orders arrived to proceed to the Gulf of Siam. While she was en route the war ended, and Rasher returned to the Philippines. She departed Subic Bay on 31 August arriving New York on 6 October, via Pearl Harbor and the Panama Canal. Following
