HMS Greyhound was a G-class destroyer built for the Royal Navy in the 1930s. Greyhound participated in the Norwegian Campaign in April 1940, the Dunkirk evacuation in May and the Battle of Dakar in September before being transferred to the Mediterranean Fleet in November. The ship generally escorted the larger ships of the Mediterranean Fleet as they protected convoys against attacks from the Italian Fleet. She sank two Italian submarines while escorting convoys herself in early 1941. Greyhound was sunk by German Junkers Ju 87 Stuka dive bombers north-west of Crete on 22 May 1941 as she escorted the battleships of the Mediterranean Fleet attempting to intercept the German sea-borne invasion forces destined for Crete.
Greyhound 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. Greyhound carried a maximum of 470 long tons (480 t) of fuel oil that gave 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 137 officers and men in peacetime, but in increased to 146 in wartime.
Sixteen different ships of the British Royal Navy have been named HMS Greyhound, after the greyhound, a breed of dog notable for its speed.
