Smith, DD-378, was a Mahan-class destroyer, the second ship of the name, named for Joseph B. Smith, who was killed in command of the frigate Congress when the Confederate ironclad Virginia destroyed her in March 1862. Mare Island Navy Yard laid her down on 27 October 1934, launched her on 20 February 1936, Mrs. Yancey S. Williams sponsoring, and commissioned her on 19 September 1936, Commander H. L. Grosskopf in command.
She escorted ships between the west coast and Pearl Harbor until April 1942, then screened Task Force 1 and joined Task Force 16, the Enterprise group, on 15 October. At Santa Cruz on 26 October 1942 a formation of about 20 torpedo planes attacked her. A Japanese torpedo plane crashed into her forecastle with a heavy explosion, burst gasoline tanks set the forward part of the ship on fire, and the bridge had to be abandoned. Her gunners shot down six of the planes. By early afternoon the fires forward were out, with 57 killed or missing and 12 wounded, her magazines flooded and steering control from the pilot house temporarily lost. She kept her place in the screen.
She went to Noumea for temporary repairs, then Pearl Harbor, and was back in the South Pacific in 1943. In 1943 she bombarded Finschhafen on 23 August, shelled the Lae beaches before the Australian landings of 4 September, and took part in the Finschhafen landings. On 3 October, on an antisubmarine sweep of Huon Gulf, three torpedo wakes passed her and one hit Henley, which broke in half and sank. She shelled the beaches at Arawe on 15 December and Cape Gloucester on 26 December. On 1 January 1944 she was rammed astern by Hutchins, and on 29 February she bombarded Los Negros for the Admiralty landings. After a San Francisco overhaul she went to Eniwetok in August and sailed for Saipan with Task Group 57.9 on 24 September 1944.
She was decommissioned on 28 June 1946 and struck on 25 February 1947. NavSource says she was sold on 20 August 1947 and broken up for scrap. She earned six battle stars.
