A Soviet submarine has been lying on the Baltic Sea floor for almost 70 years, ever since it ran into a Finnish mine in early 1940. Now, a team of divers say they have found the vessel after a decade-long search. A team of Baltic Sea divers has discovered the wreckage of a submarine S-2 that sank with dozens of sailors aboard during World War II, one of the divers said Tuesday.

They found the S-2 submarine near the Aland Islands between Sweden and Finland in February but only announced it Tuesday because they wanted to confirm the identity of the vessel, team member Marten Zetterstrom said.

He said all 50 crew members died when the vessel exploded in 1940, probably after hitting a mine. He declined to give the exact location.

"I think it's been 10 years since people started searching. I've been part of it for four-five years," Zetterstrom said.

Markus Lindholm, an Aland-based expert who studied pictures of the wreck, said the claim appeared to be true.

"According to all available sources no other submarine has sunk in those waters," said Lindholm, curator of maritime archaeology at Finland's National Board of Antiquities.

The submarine was last spotted at surface level by a lighthouse keeper on the Market island, west of the Aland archipelago, Lindholm said. He said the keeper's notes of the incident have been preserved and describe how the vessel headed north before diving and entering a Finnish minefield, after which an explosion was heard.

Lindholm said pictures showed the front of the submarine was missing, apparently torn off by an explosion.

"The mine must have hit the submarine hull near the torpedo tubes and then the whole thing blew up," he said.

Zetterstrom said the divers had informed Swedish and Russian authorities about the discovery.

The divers conducted the search at their own expense. "My feelings were mixed," diver Marten Zetterstrom told about finding the vessel. "There it was, this war machine that was built to take ships down. I was happy, sad, depressed and elated all at once."

The war between the Soviet Union and Finland is a largely forgotten chapter in World War II, taking place as it did following the successful Nazi invasion of Poland and before the conflagration enveloped all of Europe.
