UB-54 was ordered 20 May 1916. She was built by AG Weser, Bremen and following just under a year of construction, launched at Bremen on 18 April 1917. UB-54 was commissioned later that same year under the command of Oblt.z.S. Egon von Werner.Like all Type UB III submarines, UB-54 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-54 would carry a crew of up to 3 officer and 31 men and had a cruising range of 9,020 nautical miles (16,710 km; 10,380 mi). UB-54 had a displacement of 516 t (508 long tons) while surfaced and 646 t (636 long tons; 712 short tons) when submerged. Her engines enabled her to travel at 13.4 knots (24.8 km/h; 15.4 mph) when surfaced and 7.8 knots (14.4 km/h; 9.0 mph) when submerged.
