German submarine U-146 was a Type IID U-boat of Nazi Germany's Kriegsmarine during World War II. Her keel was laid down on 10 April 1940 by Deutsche Werke in Kiel as yard number 277. She was launched on 16 November 1940 and commissioned on 28 December with Oberleutnant zur See Hans-Jürgen Radke in command.
U-148 began her service life with the 24th U-boat Flotilla. She was then assigned to the 21st flotilla and subsequently to the 31st flotilla. She spent the war as a training vessel.
She was scuttled in May 1945.
Design
German Type IID submarines were enlarged versions of the original Type IIs. U-148 had a displacement of 314 tonnes (309 long tons) when at the surface and 364 tonnes (358 long tons) while submerged. Officially, the standard tonnage was 250 long tons (250 t), however.[2] The U-boat had a total length of 43.97 m (144 ft 3 in), a pressure hull length of 29.80 m (97 ft 9 in), a beam of 4.92 m (16 ft 2 in), a height of 8.40 m (27 ft 7 in), and a draught of 3.93 m (12 ft 11 in). The submarine was powered by two MWM RS 127 S four-stroke, six-cylinder diesel engines of 700 metric horsepower (510 kW; 690 shp) for cruising, two Siemens-Schuckert PG VV 322/36 double-acting electric motors producing a total of 410 metric horsepower (300 kW; 400 shp) for use while submerged. She had two shafts and two 0.85 m (3 ft) propellers. The boat was capable of operating at depths of up to 80–150 metres (260–490 ft).[2]
The submarine had a maximum surface speed of 12.7 knots (23.5 km/h; 14.6 mph) and a maximum submerged speed of 7.4 knots (13.7 km/h; 8.5 mph).[2] When submerged, the boat could operate for 35–42 nautical miles (65–78 km; 40–48 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 3,800 nautical miles (7,000 km; 4,400 mi) at 8 knots (15 km/h; 9.2 mph). U-148 was fitted with three 53.3 cm (21 in) torpedo tubes at the bow, five torpedoes or up to twelve Type A torpedo mines, and a 2 cm (0.79 in) anti-aircraft gun. The boat had a complement of 25.[2]
Fate
The boat was scuttled in the Raederschleuse (lock) at Wilhelmshaven on 2 May 1945. The wreck was broken up on an unknown date.
