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 (254 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]
Fateedit
The boat was scuttled in the Raederschleuse (lock) at Wilhelmshaven on 5 May 1945. The wreck was broken up on an unknown date.
