Type UC III minelaying submarines were used by the Imperial German Navy (Kaiserliche Marine) during World War I. They displaced 474 tonnes (467 long tons) at the surface and 571 t (562 long tons) submerged, carried guns, 7 torpedoes and up to 14 mines. The ships were double-hulled with improved range and sea-keeping compared to the UC II type. The type had better seagoing, maneuvering and turning capabilities than its predecessor, while underwater stability was reduced.[1]
A total of 113 Type UC III submarines were ordered by the Imperial German Navy, but only 25 U-boats were completed before the Armistice with Germany in 1918. Of those, 16 U-boats actually served in the war. 54 building orders were cancelled in 1918, while 34 U-boats were never completed and broken up in the ship yards.
Design
German Type UC III submarines had a displacement of 491 tonnes (483 long tons) when at the surface and 571 tonnes (562 long tons) while submerged. They had a length overall of 56.51 m (185 ft 5 in), a beam of 5.54 m (18 ft 2 in), and a draught of 3.77 m (12 ft 4 in). The submarines were powered by two six-cylinder four-stroke diesel engines each producing 300 metric horsepower (220 kW; 300 shp) (a total of 600 metric horsepower [440 kW; 590 shp]), two electric motors producing 770 metric horsepower (570 kW; 760 shp), and two propeller shafts. They had a dive time of 15 seconds and were capable of operating at a depth of 75 metres (246 ft).[2]
The submarines were designed for a maximum surface speed of 11.5 knots (21.3 km/h; 13.2 mph) and a submerged speed of 6.6 knots (12.2 km/h; 7.6 mph). When submerged, they could operate for 40 nautical miles (74 km; 46 mi) at 4.5 knots (8.3 km/h; 5.2 mph); when surfaced, they could travel 9,850 nautical miles (18,240 km; 11,340 mi) at 7 knots (13 km/h; 8.1 mph). UC III-class boats were fitted with six 100-centimetre (39 in) mine tubes, fourteen UC 200 mines, three 50-centimetre (20 in) torpedo tubes (one on the stern and two on the bow), seven torpedoes, and one 10.5 cm (4.1 in) SK L/45 or 8.8 cm (3.5 in) Uk L/30 deck gun. Their complement was twenty-six crew members.[2]
