She was scuttled on 5 May 1945.
German Type IID submarines were enlarged versions of the originalType IIs.U-146 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.[3] The U-boat had a total length of 43.97 m (144 ft 3 in), apressure hull length of 29.80 m (97 ft 9 in), abeam of 4.92 m (16 ft 2 in), a height of 8.40 m (27 ft 7 in), and adraught of 3.93 m (12 ft 11 in). The submarine was powered by twoMWM RS 127 S four-stroke, six-cylinderdiesel engines of 700 metric horsepower (510 kW; 690 shp) for cruising, twoSiemens-Schuckert PG VV 322/36double-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).[3]
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).[3] 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-146 was fitted with three 53.3 cm (21 in)torpedo tubes at the bow, fivetorpedoes or up to twelve Type A torpedo mines, and a2 cm (0.79 in) anti-aircraft gun.

The submarine's first patrol commenced with her departure from Kiel on 17 June 1941. She crossed theNorth Sea and negotiated thegap between theFaroe andShetland Islands. She sankPluto 100 nmi (190 km; 120 mi) north north-west of theButt of Lewis (in theOuter Hebrides, Scotland). She then sailed to a point south-west of Ireland.
For her second patrol, she left Kiel on 26 July 1941. Her return was on 11 August. No further details are available.
