German submarine U-1222 was a Type IXC/40 U-boat built for Nazi Germany's Kriegsmarine during World War II.

Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-1222 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 long tons) while submerged.^[2] The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).^[2]

The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).^[2] When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,850 nautical miles (25,650 km; 15,940 mi) at 10 knots (19 km/h; 12 mph). U-1222 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) as well as a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of forty-eight.^[2]

Service history

U-1222 was ordered in August 1941 from Deutsche Werft in Hamburg-Finkenwerder under the yard number 385. Her keel was laid down on 2 November 1942 and was launched the following year on 6 June 1943. About three months later she was commissioned into service under the command of Kapitänleutnant Heinz Bielfeld (Crew 34) in the 4th U-boat Flotilla.

After work-up for deployment, U-1222 tranfered to the 10th U-boat Flotilla and left Kiel for the West Atlantic on 13 April 1944 for her first and only patrol. Stopping briefly in Marvik, Norway, for replenishment, she operated with no success south of Nova Scotia.

Returning from patrol, U-1222 was charging her batteries while submerged, when her snorkel was spotted by a British aircraft, Sunderland 'P' of No. 201 Squadron RAF, on 11 July 1944 off La Rochelle. The aircraft immediately attacked the U-boat with depth charges and sunk her. All 56 crew members died in the event.^[1]
