"heavy" loss of life could easily suggest 2/3 or even 3/4. In fact, only 12 survived-- fewer than 2%. |

SM U-75 was one of the 329 submarines serving in the Imperial German Navy in World War I. U-75 was engaged in naval warfare and took part in the First Battle of the Atlantic. On her first mission, U-75 laid the mine that sank the cruiser HMS Hampshire during her voyage to Russia carrying British Secretary of State for War Lord Kitchener. The cruiser sank at 59°07′N 03°24′W / 59.117°N 3.400°W west of the Orkney Islands with nearly total loss of life in a force 9 gale.
Design
German Type UE I submarines were preceded by the longer Type U 66 submarines. U-75 had a displacement of 755 tonnes (743 long tons) when at the surface and 832 tonnes (819 long tons) while submerged.[2] She had a total length of 56.80 m (186 ft 4 in), a pressure hull length of 46.66 m (153 ft 1 in), a beam of 5.90 m (19 ft 4 in), a height of 8.25 m (27 ft 1 in), and a draught of 4.86 m (15 ft 11 in). The submarine was powered by two 900 metric horsepower (660 kW; 890 shp) engines for use while surfaced, and two 800 metric horsepower (590 kW; 790 shp) engines for use while submerged. She had two propeller shafts. She was capable of operating at depths of up to 50 metres (160 ft).[2]
The submarine had a maximum surface speed of 9.9 knots (18.3 km/h; 11.4 mph) and a maximum submerged speed of 7.9 knots (14.6 km/h; 9.1 mph).[2] When submerged, she could operate for 83 nautical miles (154 km; 96 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 7,880 nautical miles (14,590 km; 9,070 mi) at 7 knots (13 km/h; 8.1 mph). U-75 was fitted with two 50 centimetres (20 in) torpedo tubes (one at the port bow and one starboard stern), four torpedoes, and one 8.8 cm (3.5 in) SK L/30 deck gun. She had a complement of thirty-two (twenty-eight crew members and four officers).[2]
