German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-244 had a displacement of 769t when at the surface and 871t while submerged. She had a total length of 67.1m (220.1feet), a pressure hull length of 50.5m (165.7feet), a beam of 6.2m (20.3feet), a height of 9.6m (31.5feet), and a draught of 4.74m (15.55feet). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of NaNPS for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of 750PS for use while submerged. She had two shafts and two 1.23abbr=onNaNabbr=on propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-244 was fitted with five 53.30NaN0 torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.82NaN2 SK C/35 naval gun, (220 rounds), one 3.7cm (01.5inches) Flak M42 and two twin 2sp=usNaNsp=us C/30 anti-aircraft guns.

After training with the 5th U-boat Flotilla at Kiel, U-244 was transferred to the 9th flotilla for front-line service on 1 August 1944. She was reassigned to the 11th flotilla on 1 November.
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-244s departure from Bergen on 9 August 1944. Her route took her south of Iceland. She returned to Bergen on 1 November.
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.
Her third foray saw her reach as far as the English Channel, off Worthing. At 64 days, it was her longest patrol.
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.
