German submarine U-310 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 30 January 1942 at the Flender Werke yard at Lübeck as 'werk' 310, launched on 3 January 1943 and commissioned on 24 February under the command of Leutnant Klaus Friedland.

During her career, the U-boat sailed on six combat patrols, sinking two ships, before she surrendered in May 1945.^[1]

She was a member of seven wolfpacks.

Service history

The boat's service life began with training with the 8th U-boat Flotilla in February 1943. She was then transferred to the 7th flotilla for operations on 1 August. She was reassigned to the 13th flotilla on 5 September 1944.

The boat made two short journeys from Kiel in Germany to Marviken and Egersund in Norway, between June and August 1944.

1st patrol

The submarine's first patrol began with her departure from Egersund (south of Stavanger), on 13 September 1944. She moved up the Norwegian coast, arriving in Narvik on the 21st.

2nd patrol

The boat torpedoed the Edward H. Crockett on 29 September 1944. The wreck was finished off with gunfire from HMS Milne. She also sank the Samsuva in the same attack off the North Cape.

3rd, 4th and 5th patrols

U-310's third sortie covered the Norwegian and Barents Seas.

In her fourth patrol, the U-boat rounded Bear Island and passed east of Murmansk.

Her fifth foray began in Harstad (northwest of Narvik), on 25 December 1944 and ended in Bogenbucht, (west of Narvik), on 5 January 1945.

6th patrol and fate

The U-boat's last patrol was relatively uneventful. She finished in Trondheim at war's end. There, she was broken up in March 1947.
