German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-408 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).
The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-408 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and a 2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.
The submarine was laid down on 30 September 1940 at the Danziger Werft at Danzig (now Gdansk) as yard number 109, launched on 16 July 1941 and commissioned on 19 November under the command of Korvettenkapitän Reinhard von Hymmen.
She served with the 5th U-boat Flotilla from 19 November 1941 for training and the 9th flotilla from 1 May 1942 for operations. She was reassigned to the 11th flotilla on 1 July 1942 and served with that organization until her loss.
U-359's first patrol was preceded by a move from Kiel in Germany to Skjomenfjord in Norway. She left there for her first patrol on 7 June, sailing through the north Norwegian Sea into the Barents Sea. She returned to Skjomenfjord on 16 July.
The boat set-out on her second foray on 10 September 1942. She sank Stalingrad on the 13th, 100 nmi (190 km; 120 mi) southwest of Spitsbergen. She also sank Oliver Ellsworth with the same spread of torpedoes. The master of the Soviet ship, A. Sakharov, was awarded the George Cross after acting as pilot for his convoy and spending 40 minutes in the freezing water.
The next day she sank Atheltemplar south-west of Bear Island.
3rd patrol and loss
The submarine's third and last sortie began from Narvik on 31 October 1942. On 5 November she was sunk by a US PBY Catalina from VP-84 north of Iceland. Her previous track was from the east, towards the Denmark Strait, (which separates Greenland from Iceland).
Forty-five men died in U-408; there were no survivors.
U-408 took part in two wolfpacks, namely.
- Eisteufel (21 June - 10 July 1942)
- Trägertod (12–22 September 1942)
