HMS Hesperus was an H-class destroyer that had originally been ordered by the Brazilian Navy with the name Juruena in the late 1930s, but was bought by the Royal Navy after the beginning of World War II in September 1939 and later renamed. She was damaged by German aircraft during the Norwegian Campaign in May 1940 and was assigned to convoy escort and anti-submarine patrols after her repairs were completed. The ship was assigned to the Western Approaches Command for convoy escort duties in late 1940. She was briefly assigned to Force H in 1941, but her anti-aircraft armament was deemed too weak and she was transferred to the Newfoundland Escort Force the next month for escort duties in the North Atlantic. Hesperus was transferred to the Mid-Ocean Escort Force in late 1941 and continued to escort convoys in the North Atlantic for the next three years. She was converted to an escort destroyer in early 1943 after suffering damage from one of her two ramming attacks that sank German submarines. The ship sank two other submarines during the war by more conventional means. After the end of the war, Hesperus escorted the ships carrying the Norwegian government in exile back to Norway and served as a target ship through mid-1946. She was scrapped beginning in mid-1947.
Hesperus displaced 1,350 long tons (1,370 t) at standard load and 1,883 long tons (1,913 t) at deep load. The ship had an overall length of 323 feet (98.5 m), a beam of 33 feet (10.1 m) and a draught of 12 feet 5 inches (3.8 m). She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of 34,000 shaft horsepower (25,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). Steam for the turbines was provided by three Admiralty 3-drum water-tube boilers. Hesperus carried a maximum of 470 long tons (480 t) of fuel oil, giving her a range of 5,530 nautical miles (10,240 km; 6,360 mi) at 15 knots (28 km/h; 17 mph). The ship's complement was 152 officers and enlisted men.
