Sweden says sub wreck a Tsarist Russian vessel

Sweden said today the wreck of a submarine found off its coast appeared to be a Tsarist-era Russian vessel that collided with a Swedish ship about a century ago.
"We are most likely talking about the Russian submarine the Som (Catfish) which sank after a collision with a Swedish vessel in 1916 during World War I and before the Russian revolution," the Swedish Armed Forces said.
Speculation had been swirling about the origins of the vessel after Swedish divers announced Monday that a submarine had been found about 1.5 nautical miles off the coast of central Sweden.
The announcement came nine months after a high-profile hunt for a mystery submarine in Swedish waters, suspected to be Russian, and some speculated that the divers had chanced upon a modern Russian vessel.

The Swedish military however quashed rumours and said the vessel was old, referring to the design of the submarine and the lettering on the outer shell seen in the pictures of the wreck taken by the divers.
The military added it did not think a full technical analysis was necessary.
Experts identified it as an Imperial Russian Navy sub that sank with an 18-member crew in May 1916 after a collision with a Swedish vessel.
