Type U 93 submarines were preceded by the shorter Type U 87 submarines. U-106 had a displacement of 798 tonnes (785 long tons) when at the surface and 1,000 tonnes (980 long tons) while submerged.[1] She had a total length of 71.55 m (234 ft 9 in), a pressure hull length of 56.05 m (183 ft 11 in), a beam of 6.30 m (20 ft 8 in), a height of 8.25 m (27 ft 1 in), and a 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/30deck 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]
