Russian submarine found in Swedish waters: ‘Completely intact’ vessel likely from World War I

The Swedish military says that Ocean X and Ixplorer teams appear to have found a Russian mini-submarine from World War I in its territorial waters.

Military officials said in a statement that the submarine likely sank in 1916 after colliding with a Swedish submarine.

Video provided by Ocean X shows Russian Cyrillic characters marking the vessel. The company said it appears “completely intact,” BBC reported Tuesday.

“I am 99.9 percent sure it’s from 1916, but the next step is to go down again and confirm it,” said Dennis Asberg, an Ocean X partner, Reuters reported.

The submarine’s measurements are said to be 66 feet long and 11.4 feet wide. Its discovery comes less than one year after the Swedish Navy conducted a massive search for a modern Russian submarine suspected of spying in its waters.
