German submarine U-469 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out one patrol. She sank no ships.

She was sunk by a British aircraft south of Iceland on 25 March 1943.[1][2]

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-469 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[3] 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 supercharged diesel 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 Siemens-Schuckert GU 343/38–8 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).[3]

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).[3] 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-469 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 one twin 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[3]

Service history[edit]

The submarine was laid down on 1 October 1941 at the Deutsche Werke in Kiel as yard number 300, launched on 8 August 1942 and commissioned on 7 October under the command of Oberleutnant zur See Emil Claussen.

She served with the 5th U-boat Flotilla from 7 October 1942 for training and the 3rd flotilla from 1 March 1943 for operations.

Patrol and loss[edit]

U-469's only patrol began with her departure from Kiel on 16 March 1943. She had just negotiated the gap between Iceland and the Faroe Islands, when she was sunk by a British B-17 Flying Fortress of No. 206 Squadron RAF – FK195/L, under Flight Lieutenant William Roxburgh – south of Iceland on the 25th.

Forty-seven men went down with U-469; there were no survivors.[1][2]

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
