She was ordered on 4 November 1940 from DeSchiMAG AG Weser Bremen, laid down on 2 November 1941, and launched on 3 July 1942.[1] She was commissioned under Kapitänleutnant Helmut Fiehn on 20 October 1942 and underwent crew training and work-ups until 31 March 1943.

Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-191 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-191 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) SK C/30 as well as a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of forty-eight.[2]

Service history

U-191 took part in several wolfpack operations in the North Atlantic. On 21 April 1943, she achieved her only success, torpedoing and sinking the 3,025-tonne Norwegian merchant ship Scebli, killing two of Scebli's crew. Two days later U-191 was attacked and sunk by the Royal Navy destroyer Hesperus off the coast of Greenland south-east of Cape Farewell with the loss of her entire crew of 55.[1]
