SM U-98 was a Type U 93 submarine and one of the 329 submarines serving in the Imperial German Navy in World War I. U-98 was engaged in the naval warfare and took part in the First Battle of the Atlantic.[5]
Design
German Type U 93 submarines were preceded by the shorter Type U 87 submarines. U-98 had a displacement of 838 tonnes (825 long tons) when at the surface and 1,000 tonnes (980 long tons) while submerged.[1] She had a total length of 71.55 m (234 ft 9 in), a pressure hull length of 56.05 m (183 ft 11 in), a beam of 6.30 m (20 ft 8 in), a height of 8.25 m (27 ft 1 in), and a draught of 3.94 m (12 ft 11 in). The submarine was powered by two 2,300 metric horsepower (1,700 kW; 2,300 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 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).[1]
The submarine had a maximum surface speed of 16.8 knots (31.1 km/h; 19.3 mph) and a maximum submerged speed of 8.6 knots (15.9 km/h; 9.9 mph).[1] When submerged, she could operate for 47 nautical miles (87 km; 54 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 8,290 nautical miles (15,350 km; 9,540 mi) at 8 knots (15 km/h; 9.2 mph). U-98 was fitted with six 50 centimetres (20 in) torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, and one 8.8 cm (3.5 in) SK L/30 deck gun. She had a complement of thirty-six (thirty-two crew members and four officers).[1]
