The USS Thatcher (DD-162) was a Wickes-class destroyer built for the United States Navy during World War I, representing a significant example of early 20th-century naval design. Laid down on June 8, 1918, at the Fore River Shipbuilding Corporation in Quincy, Massachusetts, and launched on August 31, 1918, the ship was sponsored by Miss Doris Bentley, and commissioned on January 14, 1919, under the command of Lieutenant Commander Francis W. Rockwell. Physically, as a Wickes-class destroyer, Thatcher featured the standard characteristics of her class, which generally included a length of approximately 314 feet, a beam of 30 feet, and a displacement of around 1,200 tons. She was powered by geared turbines driving twin propellers, capable of reaching speeds up to 35 knots, with a crew complement typical of her class. Operationally, Thatcher initially operated with the Atlantic Fleet, performing patrols and participating in transatlantic flights in 1919, notably operating on picket stations between Newfoundland and the Azores to support flying boat operations en route to Lisbon. She was reclassified as DD-162 in July 1920 and later transferred to the Pacific Fleet, based out of San Diego, where she conducted exercises until her decommissioning in June 1922. She remained laid-up until 1939, when she was recommissioned amid the growing tensions of World War II. In 1940, Thatcher was transferred to the Royal Canadian Navy, becoming HMCS Niagara, as part of the United Kingdom’s effort to bolster convoy escort forces against German U-boats and surface threats. Based in Scotland, she was actively engaged in convoy escort duties, notably participating in the capture of U-570 in August 1941, after a Lockheed Hudson bomber located and damaged the submarine off Iceland. Niagara took the U-boat in tow, securing her crew and transferring the vessel to Allied hands, marking a notable event in her wartime service. Throughout her service with the Royal Canadian Navy, she conducted convoy escort missions along the Atlantic, rescued survivors from torpedoed vessels, and underwent refits to maintain operational readiness. By spring 1945, she was used as a torpedo training ship before decommissioning on September 15, 1945. Ultimately, HMCS Niagara was sold for scrap in 1946, ending her distinguished career. Her service exemplifies the transition from WWI-era design to WWII convoy warfare and her role in the Allied naval efforts during the war.
