HMS Aberdeen was a Grimsby-class sloop constructed for the British Royal Navy by Thornycroft at Devonport Dockyard in Plymouth. Launched on 22 January 1936 and completed by September of the same year, she measured 266 feet 3 inches in length overall, with a beam of 36 feet and a deep load draught of 9 feet 6 inches. Her displacement was approximately 990 long tons standard, increasing to 1,355 long tons at full load. Powered by two geared steam turbines driven by Admiralty 3-drum boilers, HMS Aberdeen could reach a speed of 16.5 knots and had a range of 6,000 nautical miles at 10 knots. Initially intended to carry an improved armament with three 4-inch dual-purpose guns and a quadruple .50 inch machine gun, she was completed as a despatch vessel with reduced armament, including a single aft 4-inch gun and minesweeping gear. During her wartime service, her armament was augmented with a third 4-inch gun in 1939, four Oerlikon 20 mm cannons, and an increased number of depth charges from 15 to 60–90, with a Hedgehog anti-submarine mortar added in 1942. HMS Aberdeen’s service history was extensive. She served as a despatch vessel for the Mediterranean Fleet from November 1936, replacing older vessels, and participated in the Fleet Review for King George VI’s coronation in 1937. With the outbreak of WWII, she was redeployed for convoy escort duties in the English Channel, Western Approaches, North Sea, and Atlantic routes. She participated in operations including Operation Torch in 1942. Notably, during the escort of convoy HX229A in March 1943, she ran aground on the ice-edge, suffering hull damage and loss of submarine detection equipment. She underwent repairs and was fitted with advanced radar and radio communication gear. Throughout the war, HMS Aberdeen remained active in convoy defense, air-sea rescue, and patrol duties, especially around Freetown, Sierra Leone. After VE Day, she continued local patrols before being paid off into reserve at Gibraltar in 1945. She was sold for scrap in December 1948 and broken up at Hayle, Cornwall, completing her distinguished service as a capable escort vessel of the Grimsby class.
