Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-544 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.^[2] 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).^[2]

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).^[2] 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-544 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.^[2]

Service history

Patrol and loss

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

She was sunk on 16 January 1944 northwest of the Azores by American aircraft from the escort carrier USS Guadalcanal using rockets and depth charges.

Fifty-seven men died; there were no survivors.^[1]

Wolfpacks

U-544 took part in five wolfpacks, namely:

Coronel (4 – 8 December 1943)
Coronel 1 (8 – 14 December 1943)
Coronel 2 (14 – 17 December 1943)
Föhr (18 – 23 December 1943)
Rügen 6 (26 – 31 December 1943)
