The USS Sculpin (SS-191) was a Sargo-class submarine constructed for the United States Navy, notable for its active service during World War II and its ultimate loss in 1944. Her keel was laid on September 7, 1937, at the Portsmouth Navy Yard in Kittery, Maine, and she was launched on July 27, 1938. The vessel was commissioned on January 16, 1939, under the command of Lieutenant Warren D. Wilkin. As a Sargo-class submarine, Sculpin featured typical design elements of her class, though specific physical specifications are not detailed on the page. Initially, Sculpin conducted her shakedown cruise in May 1939, during which she assisted in the rescue operation of the Squalus, a sunken test vessel. Her role included establishing communication and aiding in salvage efforts, highlighting her early contribution to naval rescue operations. After type training off the Atlantic coast, she was transferred to the Pacific Fleet, arriving at Pearl Harbor in March 1940. She engaged in local operations and training until the outbreak of World War II. Throughout her wartime service, Sculpin conducted numerous patrols across the Pacific, including off the Philippines, Java, the Banda Sea, and near Truk. She was credited with sinking three Japanese ships totaling approximately 9,835 tons. Her combat record includes successful torpedo attacks, such as damaging a Japanese destroyer and sinking vessels like Naminoue Maru and Sekko Maru. However, her service was marred by torpedo malfunctions common to early war conditions, leading to many unproductive patrols. Sculpin's final patrol began in November 1943, during which she attempted to intercept Japanese shipping near Truk. She encountered a large convoy on November 19, 1943, but was detected and attacked. After sustaining damage from depth charge attacks, her commander, Captain John P. Cromwell, chose to surface and abandon her to avoid capture. Cromwell was posthumously awarded the Medal of Honor for his heroism. The submarine was scuttled by her crew to prevent her capture, and most of her crew were taken as prisoners by the Japanese. Sculpin's loss marked the end of her distinguished but tragic wartime career, emphasizing her maritime significance as a wartime combat vessel and her role in the broader Pacific naval campaign.
