UFO News: "The recently declassified documents contain Soviet era reports detailing many cases of possible USO/UFO Sighting encounters. Former naval officer and Russian UFO researcher Vladimir Azhazha believes these documents are of great value. One of the most interesting cases he examined involved a nuclear submarine on a combat mission in the Southern Pacific. During the routine operation, the submarine detected six unknown objects traveling in formation at speeds in excess of 230 knots (265+ mph). In comparison, the fastest submarine was the Soviet K-222, which reached about 44 knots (51 mph). The submarine’s sonar determined the objects were heading straight for it so the captain gave the order to surface. The USOs/UFO followed them to the surface then flew away. Similar instances have been reported in the region of the Bermuda Triangle, as retired submarine commander Yuri Beketov recalls. Onboard instruments often malfunctioned, indicating the presence of strong interference. Many believe this is a clear sign of USO/UFO presence."
Unidentified submerged objects (USOs) are not as famous as UFOs although they are often encountered "and are the same objects as UFOs just seen underwater"" according to declassified Russian Navy records.
