SM UB-124 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the German Imperial Navy on 22 April 1918 as SM UB-124.

Construction

Main article: Type UB III submarine

She was built by AG Weser of Bremen and, following just under a year of construction, launched at Bremen on 19 March 1918. UB-124 was commissioned later the same year under the command of Oblt.z.S. Hans Oscar Wutsdorff. Like all Type UB III submarines, UB-124 carried ten torpedoes and was armed with an 8.8 cm (3.46 in) deck gun. UB-124 would carry a crew of up to three officers and 31 men and had a cruising range of 7,280 nautical miles (13,480 km; 8,380 mi). UB-124 had a displacement of 512 t (504 long tons) while surfaced and 643 t (633 long tons) when submerged. Her engines enabled her to travel at 13.9 knots (25.7 km/h; 16.0 mph) when surfaced and 7.6 knots (14.1 km/h; 8.7 mph) when submerged.
