German submarine U-323 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

She carried out no patrols and sank or damaged no ships.

The boat was scuttled on 5 May 1945 in northern Germany.

Design

Like all Type VIIC/41 U-boats, U-323 had a displacement of 759 tonnes (747 long tons) when at the surface and 860 tonnes (850 long tons) while submerged. 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), and a draught of 4.74 m (15 ft 7 in).^[3] The submarine was powered by two Germaniawerft F46 supercharged six-cylinder four-stroke 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) and two Garbe, Lahmeyer & Co. RP 137/c double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. The boat was capable of operating at a depth of 250 metres (820 ft).^[3]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). 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).^[3] U-323 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), one 3.7 cm (1.5 in) Flak M42 and two 2 cm (0.79 in) C/30 anti-aircraft guns. Its complement was between forty-four and sixty.^[3]

The submarine was laid down on 12 March 1942 by the Flender Werke yard at Lübeck as yard number 323, launched on 12 January 1944 and commissioned on 2 March under the command of Kapitänleutnant Siegfried Pregel.

She served with the 4th U-boat Flotilla for training, from 2 March 1944 to 5 May 1945. The boat was scuttled on 5 May 1945 near Nordenham, (across the River Weser from Bremerhaven).
