Design

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).[3]

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).

2 cm (0.79 in) C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.[3]

Service history

The submarine was

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-408'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 1942.

Second patrol

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
.

Third patrol and loss

The submarine's third and last sortie began from

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)
