SM UB-29 was a German Type UB II submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 30 April 1915 and launched on 31 December 1915. She was commissioned into the German Imperial Navy on 18 January 1916 as SM UB-29.^{[Note 1]}

The submarine sank 31 ships in 17 patrols for a total of 35,562 gross register tons (GRT).^[5] UB-29 was sunk by two depth charges from HMS Landrail south of Goodwin Sands at 51°9′N 1°46′E / 51.150°N 1.767°E / 51.150; 1.767Coordinates: 51°9′N 1°46′E / 51.150°N 1.767°E / 51.150; 1.767 on 13 December 1916.^[2]

Design

A German Type UB II submarine, UB-29 had a displacement of 265 tonnes (261 long tons) when at the surface and 291 tonnes (286 long tons) while submerged. She had a total length of 36.13 m (118 ft 6 in), a beam of 4.36 m (14 ft 4 in), and a draught of 3.66 m (12 ft). The submarine was powered by two Benz six-cylinder diesel engines producing a total 267 metric horsepower (263 shp; 196 kW), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft. She was capable of operating at depths of up to 50 metres (160 ft).^[2]

The submarine had a maximum surface speed of 9.15 knots (16.95 km/h; 10.53 mph) and a maximum submerged speed of 5.81 knots (10.76 km/h; 6.69 mph). When submerged, she could operate for 45 nautical miles (83 km; 52 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 6,650 nautical miles (12,320 km; 7,650 mi) at 5 knots (9.3 km/h; 5.8 mph). UB-29 was fitted with two 50 centimetres (20 in) torpedo tubes, four torpedoes, and one 5 centimetres (2.0 in) SK L/40 deck gun. She had a complement of twenty-one crew members and two officers and a thirty-second dive time.^[2]
