Swedish Armed forces released a statement regarding a submarine that never returned after voyage undersea in 1941, "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 Öland."

According to Russian media, the submarine was discovered by Swedish civilian divers southeast of Öland. After being localized by HMS Belos, a submarine rescue ship, pictures were taken of the wreckage S-6 Soviet submarine that went missing in 1941. The remains of the wreck were found by the "Wartburg minefield within Sweden's economic zone, but in international waters.

It is a mystery to what may have caused the ship to be destroyed but Commander Christian Allerman of the Swedish Navy said, "Boats at the time often sailed on the surface in order to quickly flee and/or to recharge their batteries." One theory is that during World War II, the submarine sailed into a German minefield and was destroyed.

The submarine remained in two main pieces. The bow rested 2 meters north of the stern, found next to a torpedo-shaped object. The submarine was imprinted with Russian text and symbols of a Soviet hammer and sickle.
