SM UC-76 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (Template:Lang-de) during World War I. The U-boat was ordered on 12 January 1916 and was launched on 25 November 1916. She was commissioned into the German Imperial Navy on 17 December 1916 as SM UC-76.[Note 1] In 2 patrols UC-76 was credited with sinking 15 ships, either by torpedo or by mines laid. UC-76 was surrendered on 1 December 1918 and broken up at Brighton Ferry in 1919–20.[1]
Design
A German Type UC II submarine, UC-76 had a displacement of 410 tonnes (400 long tons; 450 short tons) when at the surface and 493 tonnes (485 long tons; 543 short tons) while submerged. It had a total length of 165 ft 6 in (50.44 m), a beam of 5.28 m (17 ft 4 in),[2] and a draught of 4 m (13 ft 1 in).[4] The submarine was powered by two six-cylinder four-stroke diesel engines each producing 500 metric horsepower (490 shp; 370 kW) (a total of 1,000 metric horsepower (990 shp)*, two electric motors each producing 340 kilowatts (460 shp; 460 PS), and two propeller shafts. It had a dive time of 30 seconds[2] and was capable of operating at a depth of 50 metres (160 ft).[4]
The submarine had a maximum surface speed of 11.8 knots (21.9 km/h; 13.6 mph) and a submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). When submerged, it could operate for 52 nautical miles (96 km; 60 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, it could travel 8,660 to 10,230 nautical miles (16,040 to 18,950 km; 9,970 to 11,770 mi) at 7 knots (13 km/h; 8.1 mph).[2] UC-76 was fitted with six 100 centimetres (39 in) mine tubes,[4] 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 centimetres (3.5 in) KL/30 deck gun.[2] Its complement was twenty-six crew members.[4]
