German submarine U-144 was a Type IID U-boat of Nazi Germany's Kriegsmarine during World War II. She was laid down on 10 January 1940 by Deutsche Werke of Kiel and commissioned on 2 October 1940.[1]

Design

German Type IID submarines were enlarged versions of the original Type IIs. U-144 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-144 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]

Service history

In three patrols, U-144 sank one submarine for a total of 206 tons. The Soviet submarine M-78 was torpedoed and sunk, west of Windawa/Windau (Ventspils) in position Lua error in package.lua at line 80: module 'strict' not found. on 23 June 1941.

Fate

U-144 was sunk on 10 August 1941 in the Gulf of Finland north of Hiiumaa, in approximate position Lua error in package.lua at line 80: module 'strict' not found., by torpedoes from the Soviet submarine ShCh-307. All 28 men inside were killed.
