ww2dbaseOrdered in mid-1942, USS Blenny was commissioned into service in mid-1944 with Lieutenant Commander W. H. Hazzard in command. She conducted four war patrols in the Java Sea and the South China Sea between 10 Nov 1944 and 14 Aug 1945, destroying 8 ships (one destroyer escort, several transports, and others) totaling 18,262 tons, plus over 60 miscellaneous smaller vessels by her deck gun. After the war, she arrived at San Diego, California, United States on 5 Sep 1945. Between Aug and Nov 1946, she made a cruise to China. In 1947, she participated in a midshipman cruise to Canada. Twice between 1947 and 1949, she sailed to Alaskan waters. In 1951, she underwent the Greater Underwater Propulsion Power Program (GUPPY) modernization. Between May and Nov 1952, she served in the Far East, participating in the Korean War. She patrolled the west coast of the United States in 1953. On 24 May 1954, she was transferred from the Pacific Fleet to the Atlantic Fleet, and her home port was switched to New London, Connecticut, United States. In 1964, she was reclassified an auxiliary submarine and received the new designation AGSS-324. She was decommissioned in Nov 1969. She was struck from the US Naval Register on 15 Aug 1973 and was sunk 15 miles off Ocean City, Maryland, United States in 1989 to form part of an artificial reef.

Steve Yerkes (above):
Personnel records were kept and most of those files became part of the serviceman’s service record held at the Navy’s Bureau of Personnel (BuPers). Those records still exist but now are maintained by the National Archives and Records Administration (NARA). A copy of your father’s service record can be requested from NARA and I strongly recommend making such a request; it will be full of fascinating stuff. See https://ww2db.com/faq/#3 for more.

Were there every personnel records kept for these boats? My father served on the Blenny as a radar operator from 1947/8 to 1952. I t would be interesting to see more pictures other than the one I have of all nine subs taken around 1950.
