She was built by AG Vulcan of Hamburg[2] and following just under a year of construction, launched at Hamburg on 5 May 1917. UB-75 was commissioned later that same year . Like all Type UB III submarines, UB-75 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-75 would carry a crew of up to 3 officer and 31 men and had a cruising range of 8,680 nautical miles (16,080 km).[2] UB-75 had a displacement of 516 t (508 long tons; 569 short tons) while surfaced and 648 t (638 long tons; 714 short tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 7.8 knots (14.4 km/h; 9.0 mph) when submerged.[2]
