In the Baltic Sea approximately 30 miles from Stockholm, Sweden unusual craft have been reported in the water. Authorities believed it to be a Russian submarine initially and although the Russians denied it which would be typical, not all witnesses agree it was a sub. Even the Supreme Cmdr. of Sweden’s Armed Forces has stated the object was unknown. Therefore, it falls under the category of a USO or Underwater Submersible Object until it can be identified and you can learn more about the event in a short article HERE.
