SM UB-98 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 8 August 1918 as SM UB-98.

UB-98 was surrendered on 21 November 1918 and broken up in Porthmadog in 1922. Reportedly, the steel plates of the submarine were used to line Garnedd Tunnel on the Ffestiniog Railway, but this has never been proven.

Construction

She was built by AG Vulcan of Hamburg and following just under a year of construction, launched at Hamburg on 1 July 1918. UB-98 was commissioned later the same year under the command of Oblt.z.S. Richard Scheurlen. Like all Type UB III submarines, UB-98 carried 10 torpedoes and was armed with a 10.5 cm (4.13 in) deck gun. UB-98 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-98 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.
