The USS Snapper (SS-185) was a Salmon-class submarine constructed by the Portsmouth Navy Yard in Kittery, Maine. Its keel was laid on July 23, 1936, and it was launched on August 24, 1937, with Mrs. Katharine R. Stark as sponsor. The vessel was commissioned on December 16, 1937, and featured typical design characteristics of the Salmon-class, which was known for its improved range and diving capabilities. After her commissioning, Snapper conducted her shakedown cruise in May 1938, visiting Cuba, the Panama Canal Zone, Peru, and Chile, before returning to Portsmouth. She was assigned to Submarine Squadron 3 at Balboa, Panama, engaging in training and fleet exercises until March 1939. Subsequently, she transferred to the West Coast, arriving at San Diego in June 1939, and later participated in maneuvers around Pearl Harbor. Overhauls at Mare Island Navy Yard in California took place in late 1939 and early 1940, ensuring her readiness for wartime operations. During the outbreak of World War II, Snapper was operating in the Philippine Islands area when the Japanese attack on Pearl Harbor occurred. Her first war patrol commenced in December 1941, focusing on shipping lanes between Hong Kong and Hainan Strait, with subsequent patrols across Southeast Asia and the South China Sea. Notably, she sank the passenger-cargo ship Tokai Maru and the cargo ship Kenryu Maru, as well as the minelayer Ajiro, during her later patrols. Her combat record includes multiple successful torpedo attacks and the rescue of personnel, such as evacuees from Corregidor. In addition to offensive actions, Snapper performed lifeguard duties supporting air strikes, notably near Truk, where she sustained minor damage from enemy aircraft. Her operational history includes encounters with enemy vessels, close calls with Allied aircraft, and the sinking of several Japanese ships, making her a notable contributor to the U.S. Navy’s Pacific War efforts. After her final patrol in October 1945, Snapper was decommissioned in November 1945, after serving extensively in wartime operations. She was struck from the Naval Vessel Register in April 1948 and sold for scrap in May of that year. Throughout her service, USS Snapper exemplified the capabilities and resilience of the Salmon-class submarines, contributing significantly to U.S. naval operations during World War II.
