Type U19 was a class of U-boats built during World War I by the Kaiserliche Marine. Type U 19 U-boats were the first U-boats with Diesel engines for surface propulsion and charging the batteries for the electrical engines. Originally the preceding Type U 17 submarine was intended to be the first diesel U-boat, but delays in developing these diesel engines meant that these two Type U 17 U-boats received Kerosene engines instead. Other improvements included the change from 45-cm to 50-cm torpedo tubes for launching the G6 torpedo, and the installation of a deck gun. [3]
The four Type 19 U-boats were ordered on 25 November 1910 from the Kaiserliche Werft Danzig shipyard. [3]
Type U 19s had an overall length of 64.15 m (210 ft 6 in) The boats' beam was 6.10 m (20 ft 0 in), the draught was 3.58 m (11 ft 9 in), with a total height of 7.30 m (23 ft 11 in). The boats displaced 650 tonnes (640 long tons) when surfaced and 837 t (824 long tons) when submerged. [1] [4]
Type U 19s were fitted with two MAN 8-cylinder two-stroke diesel engines with a total of 1,700 metric horsepower (1,250 kW ; 1,677 bhp ) for use on the surface and two AEG double-acting electric motors with a total of 880 kW (1,196 PS; 1,180 shp) for underwater use. These engines powered two shafts, which gave the boats a top surface speed of 15.4 knots (28.5 km/h; 17.7 mph), and 9.5 knots (17.6 km/h; 10.9 mph) when submerged. Cruising range was 9,700 nautical miles (18,000 km; 11,200 mi) at 8 knots (15 km/h; 9.2 mph) on the surface and 80 nautical miles (150 km; 92 mi) at 5 knots (9.3 km/h; 5.8 mph) submerged. [1] Diving depth was 50 m (164 ft 1 in). [4]
The U-boats were armed with four 50 cm (20 in) torpedo tubes, two fitted in the bow and two in the stern, and carried six torpedoes. The boats' complement was 4 officers and 31 enlisted. [1] [4]
