German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-606 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[2] She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder superchargeddiesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[2]
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).[2] When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-606 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]
Service history
The boat's career began with training at 5th U-boat Flotilla on 22 January 1942, followed by active service on 1 September 1942 as part of the 11th Flotilla. After just two months, on 1 November 1942, she transferred to 9th Flotilla.
In three patrols she sank three merchant ships, for a total of 20,527 gross register tons (GRT), plus 2 merchant ships damaged for a total of 21,925 GRT.
Convoy ON 166
Along with U-92, U-186, U-225, U-332, U-529, U-600, U-604, U-623, U-628, U-653 and U-753 she attacked Convoy ON 166 and was very successful sinking the British Empire Redshank and US ship Chattanooga City and damaging US ship Expositor (finished by U-303) on 22 February, before being damaged by depth charges launched from the destroyer ORP Burza.[3]
U-606 was sunk on 22 February 1943 in the North Atlantic in position 47°44′N33°43′W / 47.733°N 33.717°W / 47.733; -33.717. She was damaged and forced to submerge by depth charges from Polish destroyer Burza, then she was found by USCGC Campbell and attacked with depth charges and gunfire.[3] Older publications claimed, that the Campbell also rammed U-606, but apparently some U-boat had just collided with the Campbell, and it is not clear if it was U-606.[3] There were 36 dead and 12 survivors (5 by the Campbell and 7 by the Burza).[3] U-606 finally sunk on 23 February near dawn.[3]
