Wahoo SS-238

The keel of USS Wahoo (SS-238) was laid 28 June 1941 at the Navy Yard in Mare Island, California. She was launched 14 February 1942 and commissioned 15 May 1942 with LCDR Marvin G. Kennedy as her first Commanding Officer.
Wahoo made seven war patrols, the first two under the command of LCDR Kennedy and the others with LCDR Dudley W. (Mush) Morton as skipper. The unusual skill and daring of these men allowed Wahoo to sink a total of 20 ships totaling 60,038 tons in the short time of seven patrols, just over a year of hunting. She was the first submarine to sink an entire Japanese convoy single-handedly.
Wahoo was lost in action during her seventh patrol, probably in the Sea of Japan, late in 1943. She was awarded the Presidential Unit Citation for her third war patrol.
