Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-280 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 AEG GU 460/8–27 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-280 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 two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.[3]

Service history

U-280 served with 8th U-boat Flotilla while training, and transferred to 3rd U-boat Flotilla on 1 August 1943 for front-line service.[1]

On 12 October 1943 U-280 sailed from Kiel on her first and only war patrol.[2] On 16 November she was attacked by a British Liberator aircraft of No. 86 Squadron RAF near Convoy HX 265, in position 49°11′N 27°32′W, south-west of Iceland. The first attack missed and the aircraft was hit by flak, knocking out one engine. However the bomber attacked again, sinking U-280 with depth charges. The Liberator safely returned to base on three engines.[1]

Wolfpacks

U-280 operated with the following Wolfpacks during her career:

  • Körner (30 October - 2 November 1943)
  • Tirpitz 3 (2–8 November 1943)
  • Eisenhart 3 (9–15 November 1943)
