SM U-76[Note 1] was a Type UE 1 submarine and one of the 329 submarines serving in the Imperial German Navy in World War I. U-76 was engaged in the naval warfare and took part in the First Battle of the Atlantic.
Design
German Type UE I submarines were preceded by the longer Type U 66 submarines. U-76 had a displacement of 755 tonnes (743 long tons) when at the surface and 832 tonnes (819 long tons) while submerged.[2] It had a total length of 186 ft 4 in (56.79 m), a pressure hull length of 153 ft 1 in (46.66 m), a beam of 19 ft 4 in (5.89 m), a height of 27 ft 1 in (8.26 m), and a draught of 15 ft 11 in (4.85 m). The submarine was powered by two 900 metric horsepower (660 kW; 890 shp) engines for use while surfaced, and two 900 metric horsepower (660 kW; 890 shp) engines for use while submerged. It had two propeller shafts. It was capable of operating at depths of up to 50 metres (160 ft).[2]
The submarine had a maximum surface speed of 10.6 knots (19.6 km/h; 12.2 mph) and a maximum submerged speed of 7.9 knots (14.6 km/h; 9.1 mph).[2] When submerged, it could operate for 83 nautical miles (154 km; 96 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 7,880 nautical miles (14,590 km; 9,070 mi) at 7 knots (13 km/h; 8.1 mph). U-76 was fitted with two 50 centimetres (20 in) torpedo tubes (one at the starboard bow and one starboard stern), four torpedoes, and one 5.5 centimetres (2.2 in) deck machine gun. It had a complement of thirty-two (twenty-eight crew members and four officers).[2]
