The USS McCook (DD-252) was a Clemson-class destroyer constructed for the United States Navy, measuring approximately 314 feet in overall length with a beam of 30 feet 10 inches and a draft of 9 feet 10 inches. Displacing about 1,090 long tons at standard load and up to 1,310 long tons at full load, the vessel was powered by four White-Forster boilers driving two Westinghouse geared turbines, which produced 27,000 horsepower, enabling speeds exceeding 35 knots. Its armament initially comprised four 4-inch/50 caliber guns, a 3-inch/23 caliber anti-aircraft gun, two .50 caliber machine guns, and twelve 21-inch torpedo tubes in four triple mounts, complemented by depth charge equipment for anti-submarine warfare. Laid down on September 10, 1918, at Bethlehem Shipbuilding in Quincy, Massachusetts, and launched on January 31, 1919, the USS McCook was commissioned on April 30 of that year. After shakedown training, she served with the Atlantic Fleet until decommissioning in 1922, remaining in reserve until 1939. Recommissioned in December 1939, she was designated for transfer to Britain under the Destroyers for Bases Agreement. Subsequently, the ship was transferred to the Royal Navy, renamed HMS Towns, and later to the Royal Canadian Navy, becoming HMCS St. Croix (I81). During her wartime service, HMCS St. Croix operated primarily as a convoy escort in the North Atlantic and the Bay of Biscay. Notable actions include sinking U-90 on July 24, 1942, and assisting in the sinking of U-87 in March 1943. She participated in intense convoy battles, notably during the German U-boat offensive in September 1943. Tragically, on September 20, 1943, HMCS St. Croix was torpedoed and sunk by U-305 during a convoy escort mission, resulting in the loss of the ship and several crew members. Her service exemplifies the critical role of destroyers in Atlantic convoy defense and the perilous nature of naval warfare during World War II.
