SM U-126^{[Note 1]} was one of the 329 submarines serving in the Imperial German Navy in World War I. U-126 was engaged in the naval warfare and took part in the First Battle of the Atlantic.^[3]

Design

Type UE II submarines were preceded by the shorter Type UE I submarines. U-126 had a displacement of 1,163 tonnes (1,145 long tons) when at the surface and 1,468 tonnes (1,445 long tons) while submerged.^[1] she had a total length of 82 metres (269 ft), a beam of 7.42 m (24 ft 4 in), a height of 10.16 m (33 ft 4 in), and a draught of 4.22 m (13 ft 10 in). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,235 metric horsepower (908 kW; 1,218 shp) engines for use while submerged. She had two shafts and two 1.61 m (5.3 ft) propellers. She was capable of operating at depths of up to 75 metres (246 ft).^[1]

The submarine had a maximum surface speed of 14.7 knots (27.2 km/h; 16.9 mph) and a maximum submerged speed of 7.2 knots (13.3 km/h; 8.3 mph).^[1] When submerged, she could operate for 35 nautical miles (65 km; 40 mi) at 4.5 knots (8.3 km/h; 5.2 mph); when surfaced, she could travel 11,470 nautical miles (21,240 km; 13,200 mi) at 8 knots (15 km/h; 9.2 mph). U-126 was fitted with four 50 centimetres (20 in) torpedo tubes (fitted at its bow), twelve torpedoes, two 100 centimetres (39 in) mine chutes (fitted at its stern), forty-two mines, one 15 cm (5.9 in) SK L/45 deck gun, and 494 rounds. She had a complement of forty (thirty-six crew members and four officers).^[1]
