Type U 19 submarine
Type U '19' 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.
The four Type 19 U-boats were ordered on 25 November 1910 from the Kaiserliche Werft Danzig shipyard.
