SM UC-8 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy (German : Kaiserliche Marine) during World War I. The U-boat had been ordered by November 1914 and was launched on 6 July 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM UC-8. [Note 1] Mines laid by UC-8 in her one patrol are not known to have sunk any ships. UC-8 ran aground on the Dutch coast near Terschelling on 4 November 1915. Interned by the Dutch, UC-8 was purchased and commissioned into the Dutch Navy as HNLMS M 1. [3] The submarine was broken up in 1932. [1]

Design

A Type UC I submarine, UC-8 had a displacement of 168 tonnes (165 long tons) when at the surface and 183 tonnes (180 long tons) while submerged. She had a length overall of 33.99 m (111 ft 6 in), a beam of 3.15 m (10 ft 4 in), and a draught of 3.04 m (10 ft). The submarine was powered by one Daimler-Motoren-Gesellschaft six-cylinder, four-stroke diesel engine producing 90 metric horsepower (66 kW; 89 shp), an electric motor producing 175 metric horsepower (129 kW; 173 shp), and one propeller shaft. She was capable of operating at a depth of 50 metres (160 ft). [6]

The submarine had a maximum surface speed of 6.20 knots (11.48 km/h; 7.13 mph) and a maximum submerged speed of 5.22 knots (9.67 km/h; 6.01 mph). When submerged, she could operate for 50 nautical miles (93 km; 58 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 780 nautical miles (1,440 km; 900 mi) at 5 knots (9.3 km/h; 5.8 mph). UC-8 was fitted with six 100 centimetres (39 in) mine tubes, twelve UC 120 mines, and one 8 millimetres (0.31 in) machine gun. She was built by AG Vulcan Stettin and her complement was fourteen crew members. [6]

SM UC-1 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy during World War I. The U-boat had been ordered by November 1914 and was launched on 26 April 1915. She was commissioned into the German Imperial Navy on 5 July 1915 as SM UC-1. Mines laid by UC-1 in her 80 patrols were credited with sinking 41 ships. UC-1 disappeared after 18 July 1917. UC-1 was sunk on 24 July 1917 by F2B Felixstowe flying boat. Standard practice was to fly along the U boat and drop 2 250lb bombs astride it, hoping to cause leaks and give time for a destroyer to collect the submariners and sink it. On this occasion, by fluke, one bomb went through the conning tower and blew the base out of UC1. MFG Mill was awarded the DFC for this but he refused to wear it because of the total loss of life <london Gazette> <MFG Mill Diaries>
