HMCS Charlottetown was a River-class frigate serving with the Royal Canadian Navy during the Second World War. Constructed as part of Canada's 1942-1943 shipbuilding program, she was laid down on 26 January 1943 by G T Davie Shipbuilding Ltd. in Lauzon and launched on 16 September 1943. The vessel was commissioned on 28 April 1944 in Quebec City and was named after Charlottetown, Prince Edward Island. Designed by William Reed of Smith's Dock Company, the River-class frigate aimed to improve upon earlier convoy escort ships like the Flower-class corvette. The design featured twin engines that increased range to approximately 7,200 nautical miles at 12 knots, nearly doubling that of a corvette. The ship's armament included a twin 4-inch (102 mm) gun mount forward, a 12-pounder gun aft, Hedgehog anti-submarine mortars, depth charge rails, and side-mounted throwers, making her well-equipped to combat U-boat threats. Notably, she was among the first RCN vessels to carry the 147B Sword horizontal fan echo sonar transmitter, enhancing underwater detection capabilities alongside improved radar and direction-finding gear. After her commissioning, HMCS Charlottetown underwent a work-up period in Bermuda before joining convoy escort group EG 16. She traveled from Halifax to Derry, Northern Ireland, and later Portsmouth, England. Throughout her service, she escorted multiple convoys, including those to Gibraltar, playing a vital role in Atlantic maritime security. In mid-1945, she was transferred to Sydney for a tropicalization refit in preparation for service in the Pacific Theater, but this was completed after the Japanese surrender in February 1946. Post-war, HMCS Charlottetown served in training duties at Esquimalt and was paid off on 25 March 1947. She was subsequently sold and scuttled in Oyster Bay, British Columbia, serving as a breakwater. Her service exemplifies Canada's significant contribution to convoy escort and anti-submarine warfare during WWII, reflecting advancements in naval design and maritime strategy of the era.
