The USS MacKenzie (DD-614) was a Benson-class destroyer constructed for the United States Navy during World War II. Laid down on 29 May 1941 by Bethlehem Shipbuilding in San Pedro, California, she was launched on 27 June 1942 and commissioned on 21 November 1942. The vessel was named in honor of Lieutenant Commander Alexander Slidell MacKenzie and was sponsored by Miss Gail Nielsen, a descendant of the ship's namesake. Designed as a Benson-class destroyer, MacKenzie measured approximately 348 feet in length with a displacement of around 1,620 tons. She was built to serve primarily in escort, patrol, and combat roles across the Atlantic and Mediterranean theaters during the war. Following her commissioning, MacKenzie transited the Panama Canal on 1 March 1943, completing shakedown and training cruises before arriving at Casco Bay, Maine, on 13 March. Her initial duties involved coastwise escort missions, which soon expanded to transatlantic convoy operations, including two voyages to the Mediterranean by June. Notably, on 16 May, she conducted two depth charge attacks on a sonar contact, which postwar German records confirmed resulted in the sinking of U-182. In July 1943, MacKenzie participated in the Sicilian campaign, arriving at Scoglitti, Sicily, to provide screening and fire support for transport vessels. She continued convoy duties between the U.S. and the Mediterranean, and later between North America and the UK. After repairs in Swansea, Wales, she resumed operations in the Mediterranean, including participation in the Anzio landings in March 1944, where she contributed to antisubmarine efforts and provided fire support. She also supported Operation Dragoon, the Allied invasion of southern France, in August 1944. Throughout 1945, MacKenzie engaged in bombardments along the Franco-Italian border, blockade operations in the Gulf of Genoa, and convoy escort duties in the Strait of Gibraltar. She remained in the Mediterranean until after the German surrender, then returned to the U.S. in July. Although intended for Pacific service, the end of hostilities led her to be decommissioned on 4 February 1946 and placed in reserve. She was struck from the Naval Vessel Register on 1 July 1971 and was sunk during fleet exercises on 1 June 1974. During her service, MacKenzie earned four battle stars for her World War II contributions.
