German submarine U-510 was a Type IXC U-boat of Nazi Germany's Kriegsmarine during World War II, which later served in the French Navy. The submarine was laid down on 1 November 1940 at the Deutsche Werft yard at Hamburg as yard number 306, launched on 4 September 1941, and commissioned on 25 November 1941 under the command of Korvettenkapitän Karl Neitzel. [1]

After training with the 4th U-boat Flotilla at Stettin, U-510 was transferred to the 10th U-boat Flotilla based at Lorient in occupied France, for front-line service on 1 August 1942. Kapitänleutnant Alfred Eick took command of the U-boat on 22 May 1943, and she was transferred to the 33rd flotilla on 1 October 1944 while operating in Southeast Asian waters. During her seven war patrols the U-boat sank twelve ships totalling 71,349  gross register tons  (GRT), damaged eight, totalling 53,289 GRT and cause three total loss, totalling 24,338 GRT. [1]

The U-boat was captured by American forces at Saint-Nazaire on 10 May 1945. Renamed Bouan she served in the French Navy from 1947 until struck on 1 May 1959. The submarine was broken up in 1960. [3]

Design

German Type IXC submarines were slightly larger than the original Type IXBs. U-510 had a displacement of 1,120 tonnes (1,100 long tons) when at the surface and 1,232 tonnes (1,213 long tons) while submerged. [4] The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.76 m (22 ft 2 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.70 m (15 ft 5 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft). [4]

The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). [4] When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,450 nautical miles (24,910 km; 15,480 mi) at 10 knots (19 km/h; 12 mph). U-510 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun with 180 rounds, as well as two anti-aircraft guns, one of 3.7 cm (1.5 in) SK C/30 and one of 2 cm (0.79 in) C/30. The boat had a complement of forty-eight men. [4]

Polk, the latter two so badly that they were later declared total losses. The U-boat returned to Lorient on 16 April. [2]

Fourth patrol

Now under the command of Oberleutnant zur See Alfred Eick, U-510 sailed from Lorient on 3 June 1943 and once again headed for the northern South American coast.
