USS Wahoo (SS-238) is a Gato-class submarine commanded by Dudley "Mush" Morton, who is regarded as the third most successful American submarine captain of the Second World War. Over the course of seven war patrols from 1942 to 1943, Wahoo was credited with 60,038 GRT from 20 ships by JANAC. The tremendous success of Wahoo's patrols influenced American submarine doctrine and made her the most respected submarine of her peers.
The loss of Wahoo on her seventh patrol, which involved sneaking into caused tremendous impact on the strategy of COMSUBPAC: no more American submarines entered Japanese waters for merchant raiding from 1943 until 1945, under the belief that Japanese waters were too dangerous due to naval mines. The Japanese ASW units who attacked Wahoo, consisting of multiple surface and air units as well as a coastal battery unit, also believed that Wahoo was sunk by mines when she dived from the surface. It was only when the wreckage of the USS Wahoo was discovered in 2006 did it become clear that Wahoo was sunk by an air-dropped bomb that detonated on her conning tower. All hands were lost, including Commander Morton.
The USS Wahoo received the Presidential Unit Citation, Asiatic-Pacific Campaign Medal with 6 battle stars, and the World War II Victory Medal for her service.
The Tench-class submarine SS-516 was planned to be named Wahoo, but was cancelled before construction began. A second Tench-class submarine, SS-518, was to be named Wahoo instead, but was similarly cancelled before construction began. The Tang-class submarine Wahoo (SS-565) was the only other submarine be completed and share the name. The USS Morton (DD-948) was named in honor of Dudley Morton.
