German submarine U-244 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 24 October 1942 at the Friedrich Krupp Germaniawerft yard at Kiel as yard number 678, launched on 2 September 1943 and commissioned on 9 September under the command of Oberleutnant zur See Ruprecht Fischer.
In four patrols, she sank no ships.
She surrendered to the Allies in May 1945.
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-244 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 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), 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).
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). 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-244 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 twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of between forty-four and sixty.
The boat's first patrol was preceded by short trips between Kiel, Horten Naval Base in Norway and Bergen, also in Norway. It was while she was travelling between these latter two places that she was attacked by two Norwegian Mosquito aircraft of No. 333 Squadron RAF on 25 July 1944. One man was killed, seven others were wounded.
The patrol proper began with U-244's departure from Bergen on 9 August 1944. Her route took her south of Iceland. She returned to Bergen on 1 November.
2nd and 3rd patrols
More short voyages followed, between Bergen and Stavanger, but they were not listed as patrols. The boat's second sortie in December 1944, passed without incident.
The submarine surrendered at Loch Eriboll in Scotland on 14 May 1945. Later that same day, she was being towed to scuttling grounds as part of Operation Deadlight when the tow parted; the boat was then sunk with gunfire from the Polish destroyer Piorun.
