USS Becuna (SS-319), now a museum in Philadelphia, underway in Pearl Harbor, 12 July 1948. Becuna joined WWII relatively late and had only modest success over five war patrols, the US annihilation of Japanese shipping leaving her with little to hunt. She is only credited with one confirmed sinking, the 1,945-ton Nichiyoku Maru on 22 February 1945, but her first war patrol featured an impressive convoy attack where she damaged four ships, scoring seven hits out of nine torpedoes fired on 17 October 1944. One of these was sunk by Hawkbill (SS- 366) an hour later, and the two submarines split credit. Becuna's other notable accomplishments of the conflict occurred when she damaged a 6,863-ton tanker a week prior, and engaged two small vessels with her deck gun on her next patrol.
