She was laid down at the Bremer Vulkan yard at Bremen-Vegesack on 22 February 1941 as yard number 22. She was launched on 19 November and commissioned on 14 January 1942 under the command of Kapit\u00e4nleutnant Heinz Rahe.       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4U-257 was assigned to the 5th U-Boat Flotilla for training, then transferred to the 3rd U-boat Flotilla for operational service.She was sunk by Allied warships in mid-Atlantic on 24 February 1944.German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-257 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10\u00a0m (220\u00a0ft 2\u00a0in), a pressure hull length of 50.50\u00a0m (165\u00a0ft 8\u00a0in), a beam of 6.20\u00a0m (20\u00a0ft 4\u00a0in), a height of 9.60\u00a0m (31\u00a0ft 6\u00a0in), and a draught of 4.74\u00a0m (15\u00a0ft 7\u00a0in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350\u00a0kW; 2,760 to 3,160\u00a0shp) for use while surfaced, two AEG GU 460\/8\u201327 double-acting electric motors producing a total of 750 metric horsepower (550\u00a0kW; 740\u00a0shp) for use while submerged. She had two shafts and two 1.23\u00a0m (4\u00a0ft) propellers. The boat was capable of operating at depths of up to 230 metres (750\u00a0ft).       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4The submarine had a maximum surface speed of 17.7 knots (32.8\u00a0km\/h; 20.4\u00a0mph) and a maximum submerged speed of 7.6 knots (14.1\u00a0km\/h; 8.7\u00a0mph). When submerged, the boat could operate for 80 nautical miles (150\u00a0km; 92\u00a0mi) at 4 knots (7.4\u00a0km\/h; 4.6\u00a0mph); when surfaced, she could travel 8,500 nautical miles (15,700\u00a0km; 9,800\u00a0mi) at 10 knots (19\u00a0km\/h; 12\u00a0mph). U-257 was fitted with five 53.3\u00a0cm (21\u00a0in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8\u00a0cm (3.46\u00a0in) SK C\/35 naval gun, 220 rounds, and two twin 2\u00a0cm (0.79\u00a0in) C\/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.Table of ContentsService history[edit]First patrol[edit]Second, third and fourth patrols[edit]Fifth patrol[edit]Sixth patrol and loss[edit]Wolfpacks[edit]References[edit]Bibliography[edit]External links[edit]Service history[edit]The boat carried out six patrols, but did not sink or damage any ships. She was a member of seven wolfpacks.First patrol[edit]U-257‘s first patrol began on 21 September 1942 from Bergen in Norway. Her route took her across the North Sea, through the gap between the Faroe and Shetland Islands and into the Atlantic Ocean. She docked at La Pallice in occupied France, on 18 October.Second, third and fourth patrols[edit]These sorties passed without major incident.Fifth patrol[edit]The boat was attacked from the air twice in one day. U-257, in the company of U-600 and U-615 was transitting the Bay of Biscay, outbound on 14 June 1943, when a Sunderland flying boat of 228 Squadron RAF unsuccessfully depth charged the three boats. In the afternoon, it was much the same story, but this time a Whitley from No. 10 OTU was involved. One man from the U-boat’s crew was wounded. A second Whitley from the same unit arrived, but could only exchange fire with the submarine as it had expended all its depth charges in a previous engagement, the boat escaped.Sixth patrol and loss[edit]The submarine had moved to St. Nazaire; she departed from this French Atlantic port on 2 January 1944. On 24 February, she was attacked and sunk in mid-Atlantic by the Canadian frigate HMCS\u00a0Waskesiu, assisted by HMS\u00a0Nene. (A former crew member from Waskesiu has stated that Nene merely picked survivors up). Thirty men died in the sinking, there were nineteen survivors.Wolfpacks[edit]U-257 took part in seven wolfpacks, namely:Luchs (27 September \u2013 6 October 1942)Falke (28 December 1942 \u2013 19 January 1943)Landsknecht (19 \u2013 28 January 1943)Seewolf (25 \u2013 30 March 1943)Adler (7 \u2013 13 April 1943)Meise (13 \u2013 20 April 1943)Specht (21 \u2013 25 April 1943)References[edit]Bibliography[edit]Bishop, Chris (2006).
