Construction schematic of the German WW I era submarine U-106

SM U-106 was one of the 329

Acasta class destroyer, and damaging "City of Lincoln", a 5,867 GRT steamer, in the Western Approaches.[3] She was lost off Terschelling after striking a mine on 7 October 1917.[4]

Design

draught of 3.90 m (12 ft 10 in). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 shp) engines for use while submerged. The boat had two propeller shafts and two 1.70 m (5 ft 7 in) propellers. The boat was capable of operating at depths of up to 50 metres (160 ft).[1]

The submarine had a maximum surface speed of 16.4 knots (30.4 km/h; 18.9 mph) and a maximum submerged speed of 8.4 knots (15.6 km/h; 9.7 mph).[1] When submerged, she could operate for 50 nautical miles (93 km; 58 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 9,280 nautical miles (17,190 km; 10,680 mi) at 8 knots (15 km/h; 9.2 mph). U-106 was fitted with six 50 centimetres (20 in) torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, one 10.5 cm (4.1 in) SK L/45, and one 8.8 cm (3.5 in) SK L/30 deck gun. She had a complement of thirty-six (thirty-two crew members and four officers).[1]

Wreck

In 2009 the Royal Netherlands Navy found the wreckage of the ship north of Terschelling, while charting sea-routes. The news was made public in March 2011, after the ship's identity had been confirmed by German authorities and the crewmembers' families had been informed. The ship will stay in place as a wargrave.[5][6]
