HMS Carnarvon Bay was a Bay-class anti-aircraft frigate constructed for the Royal Navy during World War II. Originally ordered as the Loch-class vessel Loch Maddy, her designation was changed in 1944. Built by Henry Robb of Leith, the ship was laid down on June 8, 1944, and launched on March 15, 1945, by Lady Westwood. She was designed primarily for service in the Far East, with a focus on anti-aircraft capabilities. The vessel displaced approximately 1,600 long tons at standard load and up to 2,420 long tons at deep load. She measured 307 feet (93.6 meters) in length, with a beam of 38 feet 7 inches (11.8 meters) and a draft of 12 feet 9 inches (3.9 meters). Her propulsion system consisted of two vertical triple-expansion steam engines, each driving a single shaft, powered by two Admiralty three-drum boilers. This configuration enabled her to reach a maximum speed of 20 knots (37 km/h). With a fuel capacity of 724 long tons of fuel oil, HMS Carnarvon Bay had an operational range of 9,500 nautical miles at 12 knots. Her armament was tailored for anti-aircraft defense, featuring four QF 4-inch Mark XVI guns in two twin mounts forward of the superstructure. Additional AA weaponry included two twin mounts for 40 mm Bofors guns and two twin mounts for Oerlikon 20 mm cannons, some of which were later replaced by single Bofors guns. The ship was also fitted with a 24-barrel Hedgehog spigot mortar and carried depth charges, with two rails and four throwers for 50–60 charges. After her commissioning, HMS Carnarvon Bay joined the Rosyth Flotilla in November 1945 for training duties. She made brief deployments to Oslo in January 1946 and to Scapa Flow in February before being decommissioned in April 1946. Subsequently, she served as an accommodation ship for Reserve Fleet personnel at Harwich until she was sold on August 28, 1959. Her service history reflects her role as a wartime-built vessel adapted for post-war training and reserve duties, illustrating the transitional period of Royal Navy fleet modernization.
