HMS Achates was an A-class destroyer built for the Royal Navy in the late 1920s, completed in 1930. She was designed with a standard displacement of approximately 1,350 long tons and a deep load displacement of around 1,773 long tons. Her overall length was 323 feet, with a beam of 32 feet 3 inches and a draught of 12 feet 3 inches. Achates was powered by two Brown-Curtis geared steam turbines, driven by three Admiralty 3-drum boilers, producing 34,000 shaft horsepower and enabling her to reach speeds of up to 35.5 knots during sea trials. She carried enough fuel for a range of 4,800 nautical miles at 15 knots, supporting extended operational deployments. Armament included four QF 4.7-inch Mk IX guns in superfiring pairs, two 40 mm AA guns, and two quadruple torpedo mounts for 21-inch torpedoes. The ship's design also included space for depth charges and ASDIC systems, although initially unfit, modifications over time added anti-aircraft guns and enhanced anti-submarine weaponry, including a Hedgehog launcher and increased depth charge capacity. Achates was laid down in September 1928 at John Brown & Company’s Clydebank shipyard, launched in October 1929, and commissioned in March 1930. She served initially with the Mediterranean Fleet, participating in various diplomatic missions, including visiting South America and being involved in actions during the Cyprus riots. She underwent multiple refits and reassignments, including roles as a parent ship for anti-submarine flotillas. During World War II, Achates engaged in convoy escort and patrol duties in the English Channel and North Sea. Notably, she participated in the pursuit of the Bismarck, and in May 1941, she was severely damaged after striking a British mine off Iceland, losing her bow and suffering crew casualties. After repairs, she returned to service, participating in Arctic convoys to Russia and anti-submarine operations. Achates’s service culminated during the Battle of the Barents Sea on 31 December 1942, where she was heavily damaged by German fire while defending a convoy. Despite her efforts to lay smoke and protect the convoy, she was hit, flooding increased, and she ultimately capsized and sank, with the loss of 113 crew members. Her loss marked her as a significant vessel in the Royal Navy’s wartime destroyer fleet, noted for her active service in convoy protection and engagement with German forces.
