UB-74 was commissioned later that same year under the command of Kptlt. Karl Neureuther. Like all Type UB III submarines, UB-74 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-74 would carry a crew of up to 3 officer and 31 men and had a cruising range of 8,420 nautical miles (15,590 km; 9,690 mi). UB-74 had a displacement of 508 t (500 long tons) while surfaced and 639 t (629 long tons) when submerged. Her engines enabled her to travel at 13.4 knots (24.8 km/h; 15.4 mph) when surfaced and 7.5 knots (13.9 km/h; 8.6 mph) when submerged.
