SM UC-35 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German : Kaiserliche Marine) during World War I. The U-boat was ordered on 20 November 1915 and was launched on 6 May 1916. She was commissioned into the German Imperial Navy on 2 October 1916 as SM UC-35.^{[Note 1]} In eleven patrols UC-35 was credited with sinking 48 ships, either by torpedo or by mines laid. UC-35 was sunk by gunfire from the French torpedo boat Aigli southwest of Sardinia on 16 May 1918 at 39°48′N7°42′E / 39.800°N 7.700°E / 39.800; 7.700 .^[1]

Design

A German Type UC II submarine, UC-35 had a displacement of 427 tonnes (420 long tons) when at the surface and 509 tonnes (501 long tons) while submerged. She had a length overall of 50.35 m (165 ft 2 in), a beam of 5.22 m (17 ft 2 in), and a draught of 3.65 m (12 ft). The submarine was powered by two six-cylinder four-stroke diesel engines each producing 300 metric horsepower (220 kW; 300 shp) (a total of 600 metric horsepower (590 shp; 440 kW)), two electric motors producing 460 metric horsepower (340 kW; 450 shp), and two propeller shafts. She had a dive time of 35 seconds and was capable of operating at a depth of 50 metres (160 ft).^[3]

The submarine had a maximum surface speed of 11.8 knots (21.9 km/h; 13.6 mph) and a submerged speed of 6.6 knots (12.2 km/h; 7.6 mph). When submerged, she could operate for 54 nautical miles (100 km; 62 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 10,180 nautical miles (18,850 km; 11,710 mi) at 7 knots (13 km/h; 8.1 mph). UC-35 was fitted with six 100 centimetres (39 in) mine tubes, eighteen UC 200 mines, three 50 centimetres (20 in) torpedo tubes (one on the stern and two on the bow), seven torpedoes, and one 8.8 cm (3.5 in) Uk L/30 deck gun. Her complement was twenty-six crew members.^[3]
