The submarine was laid down on 3 November 1941 at the AG Weser yard at Bremen as yard number 1046, launched on 10 August 1942 and commissioned on 22 December 1942 under the command of Korvettenkapitän Heinrich Schonder. After training with the 4th U-boat Flotilla at Stettin, the boat was transferred to the 12th U-boat Flotilla for front-line service from 1 June 1943.
She was sunk south-west of Iceland by depth charges from a British aircraft.
German Type IXD2 submarines were considerably larger than the original Type IXs. U-200 had a displacement of 1,610 tonnes (1,580 long tons) when at the surface and 1,799 tonnes (1,771 long tons) while submerged. The U-boat had a total length of 87.58 m (287 ft 4 in), a pressure hull length of 68.50 m (224 ft 9 in), a beam of 7.50 m (24 ft 7 in), a height of 10.20 m (33 ft 6 in), and a draught of 5.35 m (17 ft 7 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of 9,000 metric horsepower (6,620 kW; 8,880 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 1.85 m (6 ft) propellers. The boat was capable of operating at depths of up to 200 metres (660 ft).
The submarine had a maximum surface speed of 20.8 knots (38.5 km/h; 23.9 mph) and a maximum submerged speed of 6.9 knots (12.8 km/h; 7.9 mph). When submerged, the boat could operate for 121 nautical miles (224 km; 139 mi) at 2 knots (3.7 km/h; 2.3 mph); when surfaced, she could travel 12,750 nautical miles (23,610 km; 14,670 mi) at 10 knots (19 km/h; 12 mph). U-200 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 24 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 150 rounds, and a 3.7 cm (1.5 in) SK C/30 with 2575 rounds as well as two 2 cm (0.79 in) C/30 anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.
U-200's first and only operational war patrol began on 12 June 1943. The new submarine departed Kiel and sailed north of the British Isles, through the gap between Iceland and the Faroe Islands and into the Atlantic Ocean. On 24 June 1943 the U-boat was located by the RAF and sunk with all hands in position by depth charges from a British Consolidated B-24 Liberator of 120 Squadron. This was initially reported to be an attack on U-194 which was sunk on the same day, but that submarine was sunk by aircraft of a different unit.
