German submarine U-224 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II.

Contents

Ordered on 15 August 1940 from the Germaniawerft shipyard in Kiel, she was laid down on 15 July 1941 as yard number 654, launched on 7 May 1942 and commissioned on 20 June.

U-224 was attacked with depth charges and rammed by Canadian corvette HMCS Ville de Quebec west of Algiers on 13 January 1943. 45 crew members died when the boat sank.

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-224 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 220 ft 2 in (67.11 m), a pressure hull length of 165 ft 8 in (50.50 m), a beam of 20 ft 4 in (6.20 m), a height of 31 ft 6 in (9.60 m), and a draught of 15 ft 7 in (4.75 m). The submarine was powered by two Germaniawerft F 46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,100 to 2,400 kW; 2,800 to 3,200 shp) for use while surfaced, two AEG 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 (4.0 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-224 was fitted with five 21 inches (53 cm) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 centimetres (3.5 in) deck machine 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. [3]
