German submarine U-1200 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine which saw service during the Second World War.

Design[edit]

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-1200 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged.[1] 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).[1]

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).[1] 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-1200 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 an anti-aircraft gun. The boat had a complement of between forty-four and sixty.[1]

Service history[edit]

U-1200 keel was laid down 17 April 1943, by F. Schichau, of Danzig. She was commissioned 5 January 1944 under the command of Oberleutnant zur See Hinrich Mangels.[2]

She was assigned to 8th U-boat Flotilla for training, before joining 11th U-boat Flotilla in Norway for operational service.

Her first war patrol, on 7 October 1944, was cut short with mechanical difficulties; she returned to Bergen on 17 October. Two days later on 19 October she set out again for her patrol area in the South-Western Approaches, south of Ireland.

Fate[edit]

On the night of 10 November 1944, 60 miles south of Cape Clear, Ireland, she encountered units of the Royal Navy's 30 Escort Group. These were four Castle-class corvettes, HMS Pevensey Castle, HMS Kenilworth Castle, HMS Launceston Castle and HMS Portchester Castle, led by Cdr. Denys Rayner. Mistaking the group, which was engaged in a slow sweep of its patrol area, for a small convoy, U-1200 attempted to stalk the group, steering on a converging course. In a swift and well-executed attack, the ships of 30 EG rounded on the U-boat and destroyed her in one depth-charge attack. There were no survivors.[3][4][5]
