Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-545 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.[3] 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).[3]

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).[3] 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-545 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.[3]

Service history

Patrol and loss

edit

The boat departed Kiel on 9 December 1943, moved through the North Sea, negotiated the 'gap' between Iceland and the Faroe Islands and entered the Atlantic Ocean.

She damaged Empire Housman on 31 December. This ship was later sunk on 3 January 1944 by U-744.

The first Watch Officer (1WO), Oberleutnant zur See Hans Wilkening, was swept overboard on 26 January 1944.

On 10 February 1944 U-545 was scuttled following damage from an attack by a Vickers Wellington of No. 612 Squadron RAF. A Canadian Wellington from 407 Squadron RCAF was also involved, but was shot down.[2]

One man died in the U-boat; there were 56 survivors.[2] They were picked up by U-714 and taken to St. Nazaire in France.[1]
