April 13 - 2018 Rare German U-boat found in Skagerrak

Sea War Museum Jutland in Thyborøn, Denmark has made a new sensational discovery during its continued registration of shipwrecks in the North Sea and in the Skagerrak.
In April 2018, the museum has found the wreck of the German U-boat U-3523, which was sunk by depth bombs in Skagerrak by a British B24 Liberator aircraft on 6 May, 1945. The day before, the German forces in Denmark, Northwest Germany and the Netherlands had surrendered, and the U-boat was not on a war patrol, but probably on the run.
The U-3523 was of the new and highly advanced type XXI U-boats that could have revolutionized the submarine war if enough boats had been completed in due time. 118 boats were laid down, but only two entered active service, and none ever saw battle.
After the war, there were many rumors about top Nazis who fled in U-boats and brought Nazi gold to safety, and the U-3523 fed the rumors. The Type XXI was the first genuine submarine that could sail submerged for a prolonged time, and the U-3523 had a range that would have allowed it to sail non-stop all the way to South America. But nobody knows, if this was the U-boat’s destination, and nobody knows, if the U-boat had valuables or passengers aboard in addition to the 58 crew, all of whom perished.
At 123 meters depth
U-3523 appeared on the screen during the museum's scan of the seabed ten nautical miles north of Skagen, and the picture was very surprising. Most unusual the whole fore part of the U-boat lies buried in the seabed, while the stern is standing 20 meters above the bottom. The wreck lies at 123 meters of water, making it very difficult to access.
So far, it has been thought that the U-3523 was sunk in the waters northeast of Skagen, but the old position was heavily flawed. The U-3523 lies in fact about 9 nautical miles west of the position, which was reported by the British bomber at the time.
Sea War Museum Jutland in Thyborøn has so far found, registered and measured about 450 wrecks in the North Sea and in the Skagerrak. The museum has until now found the wrecks of 12 submarines, 3 of which are British and 9 are German.
After WW2 Britain, the United States, France and the Soviet Union took over a number of German Type XXI U-boats and used them for a number of years in order to profit from the German technology. In the Soviet Union, the submarine became known as the Whiskey class and was used in active service all the way up to the eighties.
Today, there is only one preserved Type XXI U-boat. It lies as a museum boat in the harbour in front of the German Maritime Museum in Bremerhaven.

It’s been really exciting to have just spent the last four days on board the survey ship Viña and at the SeaWar Museum in Thyborøn as part of an archaeological expedition to visit some of the key ships wrecks from the Battle of Jutland.

Each time we go back we make new discoveries. The whole journey was filmed by National Geographic Television for a new series on maritime archaeology, Drain the Oceans. The days at sea, the museum and the beauty and deep spirituality of the Jutland Memorial Park have all been covered.

I’ve been able to talk about the wrecks and the stories that they can still tell us about what happened that fateful day in May 1916. I’ve talked about the battle, what happened and why. I’m constantly reminded of the extraordinary toll of the two days of this battle and of the outcomes – many unforeseen – that resulted.

Thank you, Gert Normann Andersen, the crew of the Viña and the staff of the Sea War Museum for being at the forefront of supporting such important historical research and story-telling.       

Drain the Oceans will be appearing on the National Geographic Channel later in 2018.

Sea War Museum Jutland marks the Armistice Day by introducing a new type of lists in the museum's exhibition. At each history told in the museum, a small booklet with the names of the perished from each ship will be at the visitors’ disposal.

11 November, 1918

11 November is commemorated in many countries to remember the many millions of dead and wounded of World War I. On November 11, 1918, the Armistice was signed with a promise of early peace talks. The hostilities ended at the 11th hour on the 11th day in the 11th month.

Sea War Museum takes part in a new research project

A two-year project with support from the Danish Ministry of Culture will search to determine how fast shipwrecks deteriorate in the North Sea

Senior researcher David Gregory of the Danish National Museum's Conservation and Science Department has in collaboration with Sea War Museum Jutland in Thyborøn launched an extensive research project, which might have a decisive influence on the future conservation of the cultural heritage in the North Sea and other vulnerable waters. In cooperation with the museum in Thyborøn and Dr. Rory Quinn of Ulster University he is going to investigate how fast shipwrecks deteriorate in the North Sea.

For decades, it has been regarded as a sound policy to protect historically valuable shipwrecks in situ, i. e. on the seabed, and prohibit all intervention from the view that they thus will be available to future generations. Experience from the Baltic Sea and other protected areas have supported this position, but in the North Sea, the situation is quite different.

"Our latest studies show that a wreck in the North Sea in a worst cases scenario can deteriorate and disappear in just 30 years. Everything indicates that there is an urgent need for a more nuanced view than hitherto. In the future it will be necessary to take the conditions on the spot in consideration," David Gregory says.

He has received DKK 763,000 (102.500 €) from the Research Committee of the Ministry of Culture for his new project, and through affiliation to Sea War Museum Jutland, he has gained access to the largest database over wrecks in the North Sea. It has been created by the founder and director of the Sea War Museum, Gert Normann Andersen, who himself has dived on many of the wrecks.
