HMS Blanche (H47) was a B-class destroyer built for the Royal Navy around 1930. During the Spanish Civil War of 1936–1939, the ship spent considerable time in Spanish waters, enforcing the non-intervention measures agreed by Britain and France. She was attacked, but not damaged, by Nationalist bombers in early 1938 and was subsequently transferred to the Home Fleet. Blanche was sunk by a mine in November 1939, becoming the first British destroyer lost to enemy action in World War II.
Blanche displaced 1,360 long tons (1,380 t) at standard load and 1,790 long tons (1,820 t) at deep load. The ship had an overall length of 323 feet (98.5 m), a beam of 32 feet 3 inches (9.8 m) and a draught of 12 feet 3 inches (3.7 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 35 knots (65 km/h; 40 mph). Steam for the turbines was provided by three Admiralty 3-drum boilers. Blanche carried a maximum of 390 long tons (400 t) of fuel oil that gave her a range of 4,800 nautical miles (8,900 km; 5,500 mi) at 15 knots (28 km/h; 17 mph). The ship's complement was 134 officers and men, although it increased to 142 during wartime.
