The USS Seal (SS-183) was a Salmon-class submarine constructed by the Electric Boat Company in Groton, Connecticut, with her keel laid on 25 May 1936 and launched on 25 April 1937. She was commissioned shortly thereafter on 30 April 1937 under the command of Lieutenant Karl Goldsmith Hensel. As a Salmon-class vessel, Seal was designed for stealth and endurance, serving as a critical asset for the U.S. Navy during World War II. Seal's early operational history included shakedown cruises in the Caribbean, followed by deployments to the Panama Canal Zone, where she conducted local exercises and participated in Fleet Problem XX, testing fleet control in the Central and South American approaches. After an overhaul in New London, she transferred to the Pacific, operating from Hawaii and San Diego, conducting exercises, soundings, and patrols along the West Coast and Hawaiian waters. In late 1941, Seal was transferred to the Asiatic Fleet, arriving in Manila and beginning her wartime patrols in the Philippines. Her combat service commenced with her first war patrol in December 1941, during which she sank Hayataka Maru off Vigan and conducted multiple patrols in the Philippines, Java, and the South China Sea. Notably, she sank Tatsufuku Maru in May 1942 and engaged enemy convoys multiple times, though with limited success due to torpedo malfunctions and operational challenges. Seal’s wartime record includes sinking several Japanese vessels, including Hakuyo Maru in October 1944 and Tosei Maru in August 1944, and participating in reconnaissance and lifeguard missions. Her service was marked by encounters with enemy ships, depth charge attacks, and damage repairs, such as a significant incident in August 1944 when her conning tower hatch failed during a dive, flooding the boat and causing electrical damage. After WWII, Seal transitioned to training duties in Hawaii before returning to New London, where she remained in the Naval Reserve until her decommissioning on 15 November 1945. She was later transferred to the Reserve Fleet, served as a Naval Reserve training ship, and was ultimately struck from the Naval Vessel Register in 1956, then scrapped shortly thereafter. Seal's service exemplifies the versatility and resilience of early U.S. submarine design during critical naval engagements in World War II.
