The first USS Spadefish (SS/AGSS-411), a , was the first ship of the United States Navy to be named for the spadefish. Although she was commissioned late in the war and spent only one year in the Pacific war zone, she was able to run up a record of 88,091 tons in 21 ships and numerous trawlers sunk. Construction and commissioning Spadefish was laid down on 27 May 1943 at the Mare Island Navy Yard in Vallejo, California. She was launched on 8 January 1944, sponsored by Mrs. Mildred Florence Scanland (née Boyd), wife of Commodore Francis W. Scanland, and was commissioned on 9 March 1944, Commander Gordon W. Underwood in command. Service history First war patrol, July – September 1944 Following shakedown training along the coast of California, Spadefish departed San Francisco on 14 June and arrived at Pearl Harbor on 22 June. On 23 July, she got underway from Pearl Harbor for her maiden war patrol, as a member of a coordinated attack group with and . On 19 August, while patrolling in Philippine waters off the northwest coast of Luzon, Spadefish torpedoed and sank her first enemy target the 9,589-ton, passenger-cargo ship Tamatsu Maru. Three days later, she trailed three large tankers through Babuyan Channel along the northern Luzon coast; closed range; and fired two spreads of torpedoes, sinking the 10,023-ton tanker Hakko Maru No. 2, and damaging a second tanker that, protected by a destroyer, limped back to a shallow cove off Luzon. For several hours into the next day, Spadefish attempted to get around the escort to attack the damaged ship anchored in the cove. The submarine finally let go with four stern torpedoes at the destroyer, but the enemy zigged clear and proceeded to depth charge the entire area. Having only three torpedoes remaining, Spadefish set course for Tanapag Harbor, Saipan, to replenish her supply. On 8 September, Spadefish was patrolling in waters of Nansei Shoto when she contacted a convoy of eight cargo ships. During a daring night surface attack, she fired a total of 20 torpedoes, sinking cargo ships Nichiman Maru, Nichian Maru, Shinten Maru, and Shokei Maru and damaging another. The following morning, she fired her final four torpedoes at an escort guarding the stricken ship; but they ran under the target. The submarine's only reward on this occasion was a rain of depth charges. Although she was out of torpedoes,
