Sunken Nazi Submarines

Submarines Disasters Disasters 








The collapsing Nazi government ordered all U-boats in German ports to make their way to their bases in Norway on May 2, 1945. Two days later, the recently commissioned U-3523 joined the mission as one of the most advanced boats in the fleet. But to reach their destination, the submarines had to pass through the bottleneck of the Skagerrak – the strait between Norway and Denmark – and the UK’s Royal Air Force was waiting for them.

Several U-boats were sunk and U-3523 was destroyed in an air attack by a Liberator bomber.


U-3523 lay undiscovered on the seabed for over 70 years until it was recently located by surveyors from the Sea War Museum in Denmark. Studying the vessel will be of immense interest to professional and amateur historians alike, not least as a way of finally putting to rest the conspiracy theory that the boat was ferrying prominent Nazis to Argentina. But sadly, recovering U-3523 is not a realistic proposition. The main challenges with such wrecks lie in accurately identifying them, assessing their status as naval graves and protecting them for the future.

U-boat wrecks like these from the end of World War II are the hardest to match to historical records. The otherwise meticulous record keeping of the Kriegsmarine (Nazi navy) became progressively sparser, breaking down completely in the last few weeks of the war. But Allied records have helped determine that this newly discovered wreck is indeed U-3523. The sea where this U-boat was located was heavily targeted by the RAF because it knew newly-built boats would flee to Norway this way. More details
