SM UB-128 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 11 May 1918 as SM UB-128. [Note 1]
UB-128 was surrendered to the Allies at Harwich on 3 February 1919 in accordance with the requirements of the Armistice with Germany. After passing into British hands, UB-128 was towed to Falmouth along with five other U-boats [Note 2] for use in a series of explosive test trials by the Royal Navy in Falmouth Bay, in order to find weaknesses in their design. Following her use on 1 February 1921, UB-128 was dumped on Castle Beach and sold to R. Roskelly & Rodgers on 19 April 1921 for scrap (for £120), and partially salvaged over the following decades, although parts remain in situ. [5]
She was built by AG Weser of Bremen and following just under a year of construction, launched at Bremen on 10 April 1918. UB-128 was commissioned later the same year under the command of Kptlt. Wilhelm Canaris. Like all Type UB III submarines, UB-128 carried 10 torpedoes and was armed with a 10.5 cm (4.13 in) deck gun. UB-128 would carry a crew of up to 3 officer and 31 men and had a cruising range of 7,280 nautical miles (13,480 km; 8,380 mi). UB-128 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.
