The second USS Menhaden (SS-377) was United States Navy submarine. Launched in 1944, she operated out of Pearl Harbor until 1946, then continued in use out of various ports in the Pacific until the 1970s. She was then decommissioned and re-fitted as a remotely controlled, unmanned acoustic test vehicle known as the "Yellow Submarine", until she was scrapped in 1988. Name Menhaden was the first submarine and second vessel of the United States Navy to be named for the menhaden, a marine fish of the herring family which is abundant off the Atlantic coast from New England southward. Launch and deployment Menhaden was laid down by Manitowoc Shipbuilding Co., Manitowoc, Wisconsin, 21 June 1944; launched 20 December 1944; sponsored by Miss Mirium R. Johnson and commissioned at Manitowoc 22 June 1945. Menhaden was skippered by Commander McClintock and manned by sailors from which had been lost by grounding during the Battle of Leyte Gulf the previous October. Menhaden, the last of the Manitowoc-built boats to have commissioned service during World War II, trained in Lake Michigan until 15 July. Thence, she was floated down the Mississippi River to New Orleans where she departed for the Canal Zone 27 July. She conducted extensive training out of Balboa during the closing days of the war against Japan, and between 1 September and 16 September cruised to Pearl Harbor for duty with SubRon 19. Flagship for Admiral Nimitz On 24 November Menhaden broke the flag of Fleet Adm. Chester W. Nimitz, CINCPAC and CINCPOA. Fleet Admiral Nimitz had selected Menhaden as his flagship during Change of Command ceremonies, for she combined the new with the old. Although untried in combat, she was one of the newest boats in the Submarine Service and incorporated the latest improvements in submarine design and equipment. Moreover her "gallantly battle-tested" crew epitomized the "valor, skill, and dedicated service of submariners" during the long Pacific war. Thus, on her deck that morning Fleet Admiral Nimitz read his orders assigning him to duty as Chief of Naval Operations, and his relief, Adm. Raymond A. Spruance, read orders making him CINCPAC and CINPOA. Menhaden operated out of Pearl Harbor until 2 January 1946 when she sailed for the west coast, arriving San Francisco 8 January. Following inactivation overhaul at Mare Island, she decommissioned 31 May 1946 and entered the Pacific Reserve Fleet. She recommissioned at Mare Island 7 August 1951, Lt.
