Design
German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-408 had a displacement of when at the surface and while submerged. She had a total length of , a pressure hull length of , a beam of , a height of , and a draught of . The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to .
The submarine had a maximum surface speed of and a maximum submerged speed of . When submerged, the boat could operate for at ; when surfaced, she could travel at . U-408 was fitted with five torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one SK C/35 naval gun, 220 rounds, and a C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.
Service history
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.
First patrol
U-408s 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 1942.
Second patrol
The boat set-out on her second foray on 10 September 1942. She sank Stalingrad on the 13th, 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.
Third 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.
Wolfpacks
U-408 took part in two wolfpacks, namely:
Eisteufel (21 June – 10 July 1942)
Trägertod (12 – 22 September 1942)
