The USS Darter (SS-227) was a Gato-class submarine constructed by the Electric Boat Company in Groton, Connecticut. Her keel was laid on October 20, 1942, and she was launched on June 6, 1943, with Mrs. E. B. Wheeler serving as her sponsor. The vessel was commissioned on September 7, 1943, and quickly became an active participant in World War II Pacific theater operations. Darter's operational history began with her departure from New London, Connecticut, on October 31, 1943, en route to Pearl Harbor, arriving in late November. Her first war patrol commenced on December 21, 1943, operating in heavily traveled lanes around Truk. During this patrol, she experienced multiple repairs, including at Pearl Harbor and Tulagi, and conducted reconnaissance of Eniwetok, scoring a torpedo hit on a large ship but was subjected to severe depth-charging. Throughout her service, Darter undertook four war patrols, engaging Japanese shipping and naval forces. Notably, during her third patrol, she sank the IJN minelayer Tsugaru off Morotai on June 29, 1944, enduring heavy depth charge attacks. Her final patrol was remarkable for her role in the Battle for Leyte Gulf, where Darter, alongside USS Dace, identified and attacked the Japanese Center Force approaching Palawan Passage. She sank the heavy cruiser Atago and damaged the cruiser Takao, contributing significantly to the Allied efforts. However, her service concluded when Darter grounded on Bombay Shoal on October 24-25, 1944, during the battle. Attempts by Japanese destroyer Naganami to tow or destroy her failed; ultimately, the crew was rescued, and she was scuttled. Despite efforts to destroy her by other vessels, her hull remained largely intact for years, and her wreck was visible above the reef as of 1998. The USS Darter earned four battle stars and the Navy Unit Commendation, with her sinking totaling approximately 19,429 tons of Japanese shipping. Her service exemplifies the vital role of submarines in disrupting Japanese maritime operations during WWII.
