HMS H8
Submarine of the Royal Navy
From Wikipedia, the free encyclopedia
HMS H8 was a British H-class submarine built by the Canadian Vickers Co., Montreal. She was laid down on 19 May 1915 and commissioned in June 1915. Like other Canadian-built submarines, she was sailed across the Atlantic for service in the North Sea and as recognition of this she initially remained under the command of her Canadian captain, Lieutenant-Commander B. L. Johnson, R.N.R. with a largely reserve crew. HMS H8 was sold on 29 November 1921 in Arbroath.

Design
She had a displacement of 364 long tons (370 t) at the surface and 434 long tons (441 t) while submerged. Her total length was 150 feet 3 inches (45.8 m), with a beam of 15 feet 4 inches (4.7 m) and a draught of 12 feet (3.7 m).
Her two diesel engines provided a total power of 480 horsepower (360 kW) and her two electric motors provided 320 horsepower (240 kW) power which gave the submarine a maximum surface speed of 13 knots (24 km/h; 15 mph) and a submerged speed of 11 knots (20 km/h; 13 mph). She would normally carry 16.4 long tons (16.7 t) of fuel and had a maximum capacity of 18 long tons (18 t)[1] and a range of 1,600 nautical miles (2,963 km; 1,841 mi). The boat was armed with a 6-pounder (2.7 kg) Hotchkiss quick-firing gun and four 18-inch (457 mm) bow torpedo tubes with six 18-inch (457 mm) torpedoes carried. The complement was twenty-two crew members.
