UB-19 was sunk in the English Channel at 49°56′N 2°45′W / 49.933°N 2.750°W / 49.933; -2.750Coordinates: 49°56′N 2°45′W / 49.933°N 2.750°W / 49.933; -2.750 on 30 November 1916 by British Q ship HMS Penshurst (Q 7).^[2]

Design

A German Type UB II submarine, ‘’UB-19’’ had a displacement of 263 tonnes (259 long tons) when at the surface and 292 tonnes (287 long tons) while submerged. They had a length overall of 36.13 m (118 ft 6 in), a beam of 4.54 m (14 ft 11 in), and a draught of 3.70 m (12 ft 2 in). The submarine was powered by two Daimler six-cylinder four-stroke diesel engines each producing 284 metric horsepower (209 kW; 280 shp) (a total of 600 metric horsepower (440 kW; 590 shp)), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft. She had a dive time of 32 seconds and was capable of operating at a depth of 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 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-19 was fitted with two 50 centimetres (20 in) torpedo tubes in the bow, four torpedoes, and one 5 centimetres (2.0 in) Tk L/40 deck gun. Her complement was twenty-three crew members.^[2]
