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.

[6] Other sources states that this in fact was SM UC-36 and that UB-36 struck a mine and sank elsewhere.

The submarine was powered by two Körting six-cylinder diesel engines producing a total 284 metric horsepower (280 shp; 209 kW), two Siemens-Schuckert electric motors producing 280 metric horsepower (210 kW; 280 shp), and one propeller shaft.

When submerged, she could operate for 45 nautical miles (83 km; 52 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 6,450 nautical miles (11,950 km; 7,420 mi) at 5 knots (9.3 km/h; 5.8 mph).

She had a complement of twenty-one crew members and two officers and a 42-second dive time.
