An Unidentified Floating Object, or NGO, is an object or glow in the Earth's hydrosphere, the origin of which remains unknown. Cases are known when these objects are pursued by submarines, which is accompanied by characteristic acoustic signals, reminiscent of the croaking of a frog, which is why the submariners called them "Quakers".
During the Cold War, the military suspected that these were miniature American submarines, or stationary objects, the purpose of which was to track the boat of a potential enemy. Every year "Quakers" met more and more often, as a rule, starting from a depth of 200 meters. Their range of action has expanded from the Barents Sea to the North Atlantic. The hypothesis that these were stationary objects had to be discarded: the "Quakers" chased the boats, changing course after them, which indicated their mobility. If they are autonomous, then they must be controlled by someone, or it must be a robot with artificial intelligence, which would be too expensive even for the United States.
Those who heard the "Quakers" had a strong impression of awareness of the actions of unknown sources of sound. It seemed that the "Quakers", appearing from nowhere, were persistently trying to establish contact. Judging by the continuously changing bearing, they circled around our submarines and, changing the tone and frequency of the signals, as if inviting the submariners to talk, actively responding to the sonar "sendings" from the boats.
The Quakers themselves posed no threat to submarines. Accompanying our submarines, they followed side by side until they left some area, and then, with a last croak, disappeared as imperceptibly as they appeared. For all the years there has not been a single known clash with the "Quakers" and, moreover, the impression was created that the "Quakers" were actively demonstrating their friendliness.
Over time, NGOs and "Quakers" began to bother the command of the Navy. By the decision of the Minister of Defense Marshal A. A. Grechko, a special group was created under the intelligence management of the Navy to systematize and analyze all inexplicable phenomena occurring in the World Ocean that could pose a threat to our ships. The officers charged with collecting information traveled through the fleets, collecting everything that at least somehow related to the problem. The commander-in-chief ordered to organize a series of oceanic expeditions. One of them, the expedition of the reconnaissance ship "Khariton Laptev" in April 1970, coincided with the death of our nuclear submarine K-8 in the North Atlantic. Having interrupted the listening and recording of the sounds of the ocean strata, "Laptev" rushed towards the dying nuclear-powered ship and managed to save most of the crew.
In the early 1980s, the Quaker program was closed. The group was disbanded, and all the accumulated materials and developments on the topic disappeared in the naval archives under the heading "Top secret". It remains unclear why the group was disbanded so abruptly, and what did they find out about the Quakers?
Some of the group's former employees believe that "Quakers" are unknown living beings with a high level of intelligence. This is quite likely, because evidence of unknown inhabitants of the ocean depths abounds. This version is supported, first of all, by the workers of the St. Petersburg branch of the Institute of the Seas of the Academy of Sciences of Russia, who at one time were attracted to the topic. Perhaps this is a subspecies of a giant eel or even a plesiosaur. Or "Quakers" belong to some kind of giant architevris squid, whose dead carcasses are periodically washed ashore by waves. Unknown architects may well mistake submarines for their natural enemies - sperm whales. The behavior of the “Quakers” speaks against this version, they do not flee, but they themselves make themselves felt and do not show either fear or aggression.
The presence of senses operating in the acoustic range makes it possible that the "Quakers" have some cetacean traits, and then their interest in submarines is understandable. For example, the prehistoric cetacean Basilosaurus was serpentine, lived at great depths, and most likely possessed the same sound transmission organs as modern whales and dolphins. It is possible that creatures like Basilosaurs still inhabit the depths of the ocean. Perhaps they even evolved and now make brave forays into the upper layers of the ocean and are very worried when they meet mysterious NGOs, i.e. our submarines.

Decoders who have studied the recorded Quaker signals also disagree. Some believe that these are signals of a technical origin, while others hear something alive. At one time, it was believed that "croaking" was the business of female killer whales making very similar sounds during mating games. However, killer whales are not extinct and continue to mate quietly even today, when the "Quakers" have disappeared somewhere. They appeared in the early 70s, the peak of messages was in 1975 - 1980, and then within five years they disappeared. Since the 1990s, there have been no official reports of meetings with the Quakers.
The version that the Quakers are alien submarines is not particularly popular among the officers of the special group, although it is not completely ruled out. It is possible that it is the aliens who accompany the submarines sailing over their underwater bases, and escort the boats to the exit from these areas.
The most obvious version assumes that the "Quakers" are secret developments of the Americans who are trying to find our submarines with their help. Quite often (although not always), shortly after the appearance of the Quakers, American anti-submarine ships appeared in the area where our submarines were located. However, it was noticed that the areas of the most frequent detection of the sea serpent also coincide with the areas where powerful NATO anti-submarine forces are located. Apparently, the Americans are also worried about giant sea creatures. In the early 90s, a message flashed in the press that the US Navy was intensively studying the ocean floor and searching for unknown inhabitants of great depths, whose signals were repeatedly recorded and allegedly even partially decoded. Perhaps it was all about the same mysterious "Quakers"?
We can only guess why the research stopped so suddenly and who is hiding under the name "Quakers" - living creatures still unknown to science, secret US intelligence facilities or alien submarines.
