SM UB-53 was a German Type UB III submarine or U-boat in the Imperial German Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the Pola Flotilla of the German Imperial Navy on 21 August 1917 as SM UB-53.[nb 1]

She operated as part of the Pola Flotilla based in Cattaro. UB-53 was sunk by mines of the Otranto Barrage on 3 August 1918 at 39°40′N 18°40′E / 39.667°N 18.667°E / 39.667; 18.667 in the Otranto Strait, 10 crew members died.[3]

Construction[edit]

UB-53 was ordered by the GIN on 20 May 1916. She was built by Blohm & Voss, Hamburg[2] and following just under a year of construction, launched at Hamburg on 9 March 1917. UB-53 was commissioned later that same year . Like all Type UB III submarines, UB-53 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-53 would carry a crew of up to 3 officer and 31 men and had a cruising range of 9,040 nautical miles (16,740 km).[2] UB-53 had a displacement of 516 t (508 long tons; 569 short tons) while surfaced and 651 t (641 long tons; 718 short tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 8 knots (15 km/h; 9.2 mph) when submerged.[2]
