HMCS Champlain was a Thornycroft S-class destroyer, originally built as HMS Torbay for the Royal Navy between 1917 and 1919. Displacing approximately 1,087 tons, the vessel measured 276 feet in length with a beam of 27 feet 4 inches and a draught of 10 feet 6 inches. Its design featured a trawler-like bow with a sharply sheered, turtleback forecastle, characteristic of the Thornycroft modifications to the S-class. Propelled by two Brown-Curtis steam turbines powered by three Yarrow boilers, Champlain achieved a maximum speed of 30 knots. Armament comprised three quick-firing 4-inch/45 caliber Mk IV guns, with the forecastle gun positioned on a raised platform, alongside a QF 2-pounder "pom-pom" anti-aircraft gun and four Lewis machine guns. The vessel was also equipped with four 21-inch torpedo tubes in twin mounts, with Thornycroft ships uniquely featuring two additional 18-inch torpedo tubes for a total of six torpedoes. Originally commissioned as HMS Torbay, she served with the Royal Navy's 4th Destroyer Flotilla as part of the Atlantic Fleet until she was placed on the reserve list in March 1920. In 1927, the British government loaned her to the Royal Canadian Navy, where she was renamed HMCS Champlain after the explorer Samuel de Champlain. She was transferred and commissioned into the RCN on 1 March 1928, serving primarily as a training vessel based out of Halifax. Throughout her service, Champlain participated in goodwill cruises along the east coast of Canada and the Caribbean, often accompanied by other Canadian destroyers. Notable incidents included damage sustained during a gale in 1931 and an altercation involving crew members in Trinidad. By the mid-1930s, the ship's condition had significantly deteriorated, and plans were made for her disposal. She was paid off on 25 November 1936 and broken up in 1937, marking the end of her operational career. Her service exemplifies the interwar use of early 20th-century destroyers for training and maritime goodwill, as well as the transition toward more modern naval vessels.
