SM UB-75 was a German U-boat (a type of submarine) that served in the German Imperial Navy during World War I. She was officially added to the German Imperial Navy on September 11, 1917.
UB-75 was part of the Flanders Flotillas, a group of U-boats operating from bases in Flanders. Sadly, on December 10, 1917, she was lost at sea after hitting a mine. All the sailors on board were lost.
Building a U-Boat: The Construction of UB-75
UB-75 was built by AG Vulcan, a company located in Hamburg, Germany. It took almost a year to build her. She was launched into the water on May 5, 1917.
Later that same year, UB-75 was officially ready for duty. Like other submarines of her type, she carried 10 torpedoes. These were powerful weapons used to sink enemy ships. She also had a deck gun, which was an 8.8 cm (3.46 in) cannon mounted on her deck.
A crew of up to 3 officers and 31 sailors worked on UB-75. The submarine could travel a long distance without needing to refuel. Her cruising range was about 8,680 nautical miles (16,080 km; 9,990 mi) (nautical miles).
When UB-75 was on the surface of the water, she weighed about 516 t (508 long tons) (tons). When she was underwater, she weighed more, about 648 t (638 long tons). Her engines allowed her to travel at 13.6 knots (25.2 km/h; 15.7 mph) (knots) when on the surface. Underwater, she moved a bit slower, at 7.8 knots (14.4 km/h; 9.0 mph).
UB-75's Missions: What Ships Did She Attack?
During her short time in service, UB-75 went on two patrols. She attacked several merchant ships, which were civilian ships carrying goods. Here is a list of the ships she encountered:

In total, UB-75 sank 6 merchant ships. These ships had a combined weight of 10,777 gross register tons (GRT). She also damaged one other ship, which weighed 1,477 GRT.
