German submarine U-171 was a Type IXC U-boat of Germany's Kriegsmarine built for service during World War II. It was laid down on 1 December 1940 at the DeSchiMAG AG Weser yard at Bremen as yard number 1011, launched on 22 July 1941, and commissioned on 25 October 1941 under the command of Kapitänleutnant Günther Pfeffer.
After training with the 4th U-boat Flotilla, U-171 was transferred to the 10th U-boat Flotilla for front-line service on 1 July 1942. It was sent to patrol in the Gulf of Mexico. It was sunk by a naval mine in the Bay of Biscay 115 days into its first and only patrol, whilst returning to Lorient in occupied France, with the loss of 22 of its crew of 54. For many years it was believed Шаблон:GS was sunk by an American aircraft in what was, in reality, an unsuccessful attack on U-171 in the Gulf of Mexico.
Design
German Type IXC submarines were slightly larger than the original Type IXBs. U-171 had a displacement of Шаблон:Convert when at the surface and Шаблон:Convert while submerged.Шаблон:Sfn The U-boat had a total length of Шаблон:Convert, a pressure hull length of Шаблон:Convert, a beam of Шаблон:Convert, a height of Шаблон:Convert, and a draught of Шаблон:Convert. The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of Шаблон:Convert for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of Шаблон:Convert for use while submerged. She had two shafts and two Шаблон:Convert propellers. The boat was capable of operating at depths of up to Шаблон:Convert.Шаблон:Sfn
The submarine had a maximum surface speed of Шаблон:Convert and a maximum submerged speed of Шаблон:Convert.Шаблон:Sfn When submerged, the boat could operate for Шаблон:Convert at Шаблон:Convert; when surfaced, she could travel Шаблон:Convert at Шаблон:Convert. U-171 was fitted with six Шаблон:Convert torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one [[10.5 cm SK C/32 naval gun|Шаблон:Convert SK C/32 naval gun]], 180 rounds, and a [[3.7 cm SK C/30|Шаблон:Convert SK C/30]] as well as a [[2 cm FlaK 30|Шаблон:Convert C/30]] anti-aircraft gun. The boat had a complement of forty-eight.Шаблон:Sfn
Service history
Patrol
U-171 departed Kiel on 17 June 1942, at the end of which it was to return to Lorient, where it would be based for future sorties. It negotiated the 'gap' between Iceland and the Faroe Islands and crossed the Atlantic Ocean, entering the Gulf of Mexico.
The submarine sank the 4,351 GRT Mexican general cargo merchant ship, SS Oaxaca on 26 July 1942, at Шаблон:Coord off Corpus Christi, Texas. The ship was at the time en route from New Orleans to Tampico via Veracruz. The first spread of two torpedoes missed the ship, but a second spread, also of two eels (German U-boat slang for torpedoes), was successful when one hit the port side near the fore-part of the ship. Six of the crew of 45 died.[1]
On 1 August 1942, also in the Gulf of Mexico, U-171 came under attack from a U.S. Coast Guard J4F-1 Widgeon aircraft, causing it little damage. However, for decades it was believed that the U-boat attacked that day was Шаблон:GS; the credit for sinking U-166 went to that aircraft.
The wreckage of U-166 was discovered in 2001, just a short distance from its last victim, Robert E. Lee, meaning that the credit for the sinking of U-166 should have gone to the U.S. Navy patrol craft, PC-566, which had reported that they believed they were successful in their depth charge attack on the submarine following the U-boat's successful torpedoing of Robert E. Lee, but PC-566 were believed by investigating officials to have missed.[2]
Having not been sunk, as had been believed by the Allies, U-171 continued its patrol. On 13 August 1942 it sank the 6,779 GRT US tanker R. M. Parker Jr. at Шаблон:Coord which is about Шаблон:Convert south of Isles Dernieres, Louisiana. The ship, which was carrying water ballast, was struck by two torpedoes; the submarine then surfaced and fired five rounds from its deck gun into the wreck. The whole crew of 44 survived, being picked up eight hours later by the United States Coast Guard auxiliary Шаблон:USS.[3]
On 4 September 1942, the submarine had its final success, the Mexican tanker Шаблон:SS 6,511 GRT; again in ballast, at Шаблон:Coord. This ship had evaded three spreads of two torpedoes each, before being hit by a torpedo fired from U-171Шаблон:'s stern tube. There were 10 dead and 24 survivors.[4]
Loss
U-171 was sunk at 13:00 hours on 9 October 1942 in the Bay of Biscay near Lorient, in position Шаблон:Coord, by a mine. Twenty-two men died, thirty survived. Captain Günther Pfeffer (1914–1966), was one of the lucky ones.[5][6]
The wrecked submarine was classified as a "military cemetery" in 1999 by the French authorities: divers are then warned that going inside the boat is strictly forbidden.
