HMS H3 was a British H-class submarine built by Canadian Vickers Co, Montreal. She was laid down on 11 January 1915 and was commissioned on 3 June 1915. After commissioning she crossed the Atlantic from St. John's, Newfoundland to Gibraltar escorted by the armed merchant cruiser HMS Calgarian. She was accompanied by H1, H2 and H4. H3 was mined in the Gulf of Cattaro, Adriatic on 15 July 1916.

Design

[edit]

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)[2] 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.
