NATO intelligence has warned allies about Russia's possible test of the Poseidon supertorpedo equipped with a nuclear charge.

 The Italian publication La Repubblica wrote about it.

 According to intelligence, the Russian nuclear submarine "Bilgorod" has left its base in the White Sea beyond the Arctic Circle. The submarine is probably heading to the Kara Sea to test the Poseidon nuclear torpedo, which is also called the "weapon of the Apocalypse," the publication said.

 The Poseidon is an unmanned underwater vehicle said to be capable of traveling vast distances underwater before exploding with enough force to cause a massive nuclear tsunami designed to inundate and irradiate coastal cities.

 A polluted wave can wipe out megacities such as New York or Los Angeles. Experts explain that the same effect can be achieved with intercontinental ballistic missiles, which have existed since the 1960s.

 The K-329 "Bilhorod" submarine is considered the prototype of a new concept of war conceived by Putin's admirals in recent years, after the return of tensions in relations with the United States.

 In recent days, the Belgorod has often been mentioned in analyzes of Nord Stream diversions, as this is one of the activities for which it was designed. But his involvement was questioned, because the submarine is one of the largest in the world, and it would be extremely difficult for him to get to the Baltic undetected.

 Now the NATO allied commands have warned that they may test "Poseidon" in the Kara Sea area - a 24-meter torpedo with a nuclear warhead, probably two megatons. It is not known exactly when the warning was sent to the Allies.

 The development of "Poseidon" lasted for years with skeptical assessments of NATO officials. It is believed that some tests were carried out as early as 2015, but there were never any launches from Belgorod.

 "Few people believe that a super-torpedo can already be ready, but even a simple announcement of a test would allow the Kremlin to demonstrate a unique ability in the fight against the West: a weapon against which there is no defense," the publication said.
