SM UB-36

SM UB-36 was a German Type UB II submarine or U-boat in the German Imperial Navy (Kaiserliche Marine) during World War I. The U-boat was ordered on 22 July 1915 and launched on 15 January 1916. She was commissioned into the German Imperial Navy on 22 May 1916 as SM UB-36.

The submarine sank seven ships in twelve patrols. She herself was sunk in May 1917, but her fate is a matter of dispute. Some sources claim that UB-36 was rammed and presumably sunk by the French steamer SS Molière in the English Channel off Ushant, France, on 21 May 1917. Other sources states that this in fact was SMU UC-36 and that UB-36 struck a mine and sank elsewhere.

Design
A Type UB II submarine, UB-36 had a displacement of 274 t when at the surface and 303 t while submerged. She had a total length of 36.90 m, a beam of 4.37 m, and a draught of 3.69 m. The submarine was powered by two Körting six-cylinder diesel engines producing a total 284 PS, two Siemens-Schuckert electric motors producing 280 PS, and one propeller shaft. She was capable of operating at depths of up to 50 m.

The submarine had a maximum surface speed of 9.15 kn and a maximum submerged speed of 5.81 kn. When submerged, she could operate for 45 nmi at 4 kn; when surfaced, she could travel 6450 nmi at 5 kn. UB-36 was fitted with two 50 cm torpedo tubes, four torpedoes, and one 8.8 cm Uk L/30 deck gun. She had a complement of twenty-one crew members and two officers and a 42-second dive time.
