Sonar scans have shown that the device, raised 10ft above the seabed and measuring 200ft by 25ft, could be the base of an anti-submarine weapon.
But now former Swedish naval officer and WWII expert Anders Autellus has revealed that the structure – measuring 200ft by 25ft – could be the base of a device designed to block British and Russian submarine movements in the area. The huge steel-and-concrete structure could be one of the most important historical finds in years.
Autellus claims it would have been built of double-skinned concrete and reinforced with wire mesh to baffle radar – which could explain why the dive team’s equipment repeatedly failed near the mystery object.
‘The area was vital to the German war machine because most of the ball bearings for its tanks and trucks came from here. Without them the German army would have ground to a halt,’ explained one expert.
‘This device dwarfs anything ever found before and is an important weapons discovery,’ they added
Explorer Stefan Hogeborn – who is studying the images for the Ocean X diving team – agreed: ‘It is a good candidate for the answer to this mystery. The object lies directly underneath a shipping route.’
‘It would be of enormous weight in steel and concrete. Other Nazi anti-sub anchoring devices were nowhere near as large,’ he added.
While the Ocean Explorer team is understandably excited about their potentially earth-shattering find, others are slightly more sceptical and are questioning the accuracy of the sonar technology
The Swedish team exploring the structure have been plagued with problems.
The divers exploring a ‘UFO-shaped’ object at the bottom of the Baltic Sea said that team their equipment stops working when they approach within 200m.
Professional diver Stefan Hogerborn, part of the Ocean X team which is exploring the anomaly, said some of the team’s cameras and the team’s satellite phone would refuse to work when directly above the object, and would only work once they had sailed away.
The object was first found in May last year, but because of a lack of funding and bad timing, they have were not able to pull a team together to see for themselves – just the strange, metallic outline, and a similar disk-shaped object about 200 metres away.
During their visit, the team saw a 985-foot trail that they described ‘as a runway or a downhill path that is flattened at the seabed with the object at the end of it’.
As it was before the recent dive, the story behind the object is anyone’s guess, from a ‘plug to the inner world’ to the Millennium Falcon ship from Star Wars.
In the past, such technology has confused foreign objects with unusual- but natural – rock formations.
Part of the trouble they face, however, is that they have no way of telling what is inside the supposed cylinder- whether it is filled with gold and riches or simply aged sediment particles.
They’re hoping for the former, and history seems to be in their favour.
The Baltic Sea is a treasure trove for shipwreck hunters, as an estimated 100,000 objects are thought to line the cold sea’s floor.
The company have created a submarine that they hope will appeal to tourists and wannabe shipwreck hunters who will pay to take a trip down to the bottom of the Baltic Sea to see for themselves.
A further dive will take place in the coming weeks.
