Construction
UB-51 was ordered by the GIN on 20 May 1916. She was built by Blohm & Voss, Hamburg and following just under a year of construction, launched at Hamburg on 8 March 1917. UB-51 was commissioned later that same year under the command of Kptlt. Ernst Krafft. Like all Type UB III submarines, UB-51 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-51 would carry a crew of up to 3 officer and 31 men and had a cruising range of 9,040 nautical miles (16,740 km; 10,400 mi). UB-51 had a displacement of 516 t (508 long tons) while surfaced and 651 t (641 long tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 8 knots (15 km/h; 9.2 mph) when submerged.
