Unknown civilization or UFO? Who sent signals to the Navy from the depths of the ocean?

During the Cold War, the US Navy and the Soviet Union had encountered strange sounds on the ocean floor off the coast of Norway. Both superpowers went to great lengths to hide their submarines and detect each other’s submarines, and as a result, there were great advances in the technology required to listen for any signals from the deep ocean. As a result, the two armies heard some unusual things.

From the mid-1970s onward, Soviet submarine crews began reporting strange sounds in the waters of the Arctic and North Atlantic oceans. They were driven mad by “Quackers,” unexplained and unidentified underwater objects that moved underwater at a speed of 200 kilometers (125 miles) per hour.

NATO assumed that it was the Soviet submarines that were making the noises until finally one of the Soviet Navy commanders asked the Norwegians to catch at least one “Quacker” for him at all costs and promised to reward the Norwegians for it.

In 1991, the US submarine detection system picked up two unidentified signals at once in the Pacific Ocean. Scientists nicknamed one of them “Upsweep” and the other “Whistle.” Neither one nor the other could be identified. “Upsweep appeared every spring and fall, and the source of it was in the middle of the ocean, and Whistle was heard only once.”

In 1997, the US military and ocean explorers were alarmed by a strange signal, nicknamed “Bloop.” The US National Oceanic and Atmospheric Administration (NOAA) recorded it roughly triangulated at a remote point in the southern Pacific Ocean west of the southern tip of South America, and the autonomous hydrophone array of the Equatorial Pacific Ocean detected the sound several times.

The Bloop was heard over a distance of more than 5,000 kilometers, and is several times louder than the blue whale, the loudest known underwater animal sound. It was so strange that oceanologists began to joke that it was Cthulhu, a fictional cosmic entity created by writer HP Lovecraft. Also, scientists couldn’t guess what it was. It seemed that the sound was made by a gigantic living creature.

Finally, NASA scientists came to the conclusion that these are supposed glaciers skimming the bottom of the ocean. Oregon State University seismologist Robert Dziak confirmed that the Bloop was just an earthquake.

During the Soviet era, it was restricted to talking about UFOs and OSI, but when it disbanded, some files turned up shocking information about alien spacecraft. Declassified documents said that the Russian navy found these unidentified objects technologically superior to ground vehicles.

One of the undated accounts was the encounter of a Soviet nuclear submarine with the formation of six alien ships in the South Pacific Ocean. At a depth of 260 meters, the six disc-shaped objects were moving towards the submarine at a speed of 426 km per hour. The crew was unable to escape their pursuit and the commander ordered the crew to surface. The crew saw through the periscope that the objects came out of the water and took off at an absurdly fast speed.

According to former nuclear submarine commander Yury Beketov, many mysterious events also occurred in the Bermuda Triangle region. The devices failed for no apparent reason. He believed that UFOs were behind this.

“[In translation] We have repeatedly observed that devices record the movement of material objects at unimaginable speed. We measure some speeds: it’s about 230 knots (400 km per hour). Such speed is difficult to create on the surface, only in the air. But there is a gigantic resistance in the water. As if the laws of physics don’t apply to these objects. There is only one conclusion: the creatures that created such material objects significantly outperform us in development,” Beketov said.

Another Navy intelligence captain, Igor Barclay, claimed that the unidentified submerged objects were seen in the places where the Russian Navy and NATO fleet are concentrated. He said: “These are the Bahamas and Bermuda, Puerto Rico. UFOs are seen with special frequency in the deepest region of the Atlantic, in the south of the Bermuda Triangle and in the Caribbean.

Despite everything, something strange has been detected over the years in the oceans. There have been a number of high-profile claims regarding US Navy nuclear submarines detecting and even interacting with OSI.
