German submarine U-883 was a Type IXD/42 U-boat of Nazi Germany's Kriegsmarine in World War II.

Designed in 1942, U-883 was the only commissioned IXD/42, similar to the IXD, but with increased engine power (increased from 4400 to 5400 ehp).

Commissioned in March 1945, only weeks before the German capitulation, U-883 was surrendered at Cuxhaven on 8 May 1945. She was sunk in December as part of Operation Deadlight.

Design

German Type IXD42 submariness were considerably larger than the original Type IXs. U-883 had a displacement of 1,616 tonnes (1,590 long tons) when at the surface and 1,804 tonnes (1,776 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 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 1.85 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 19.2 knots (35.6 km/h; 22.1 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 31,500 nautical miles (58,300 km; 36,200 mi) at 10 knots (19 km/h; 12 mph). U-883 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) with 2575 rounds as well as two 2 cm (0.79 in) anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.
