UB-97 was surrendered to the Allies at Harwich on 21 November 1918 in accordance with the requirements of the Armistice with Germany. After passing into British hands, UB-97 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 7 March 1921, UB-97 was dumped on Castle Beach and sold to R. Roskelly & Rodgers on 19 April 1921 for scrap (for £50), and partially salvaged over the following decades, although parts remain in situ.[5]
Construction edit
he was built by AG Vulcan of Hamburg and following just under a year of construction, launched at Hamburg on 13 June 1918. UB-97 was commissioned later the same year under the command of Oblt.z.S. Oskar Brinkmann. Like all Type UB III submarines, UB-97 carried 10 torpedoes and was armed with a 10.5 cm (4.13 in) deck gun. UB-97 would carry a crew of up to 3 officer and 31 men and had a cruising range of 7,120 nautical miles (13,190 km; 8,190 mi). UB-97 had a displacement of 510 t (500 long tons) while surfaced and 640 t (630 long tons) when submerged. Her engines enabled her to travel at 13 knots (24 km/h; 15 mph) when surfaced and 7.4 knots (13.7 km/h; 8.5 mph) when submerged.
