A World War II era Russian submarine was discovered at the Baltic Sea and confirmed by Swedish military officials on Monday.
The Soviet vessel was lost during the early years of World War II, Swedish Armed Forces said in a statement: "In the autumn of 1941 several Russian submarines left their home bases to patrol the Baltic Sea. Several of them never returned. One of them has now been found, blown up into large pieces, southeast of Oeland."
The wreck is believed to be one of six soviet submarines that disappeared in the Baltic Sea in 1941 after possibly being hit by a German sea-mine. The military classified the find as "S-6" which relates to the other soviet submersibles lost during the war in the area.
The statement, reported by the Inquistr, continues: "There is much to indicate that the submarine headed straight into the minefield while on the surface and was blown apart by a mine."
The wrecked submarine was first reported by civilian divers during the summer months in the middle of this year, according to Reuters. Swedish submarine salvage ship HMS Belos in the following months confirmed the previous reports.
The Swedish military informed their Russian counterparts about the discovery in order to give family members and the Russian navy the chance to have a memorial ceremony at the site.
Several Soviet submarines sunk during World War Two have been found in Swedish waters over the years.
This is the second sub wreck found in Swedish waters in recent years, according to Yahoo. Another Soviet sub was discovered in the Baltic in 2009 that was destroyed by German mines during World War II.
