הטורפדו הגרעיני הרוסי פוסידון יכול לחולל צונמי WHY RUSSIA’S 'POSEIDON' UNMANNED UNDERWATER DRONE ?

President Vladimir Putin during his state-of-the-nation address to the Russian Federal Assembly in March, showcased several weapons.
One of them was Poseidon (Status-6) unmanned underwater drone. It will be carried by a new nuclear-powered submarine currently under construction.
Poseidon is one of a kind and poses a real challenge to Russia’s rivals. 

In this video, Defense Updates analyzes WHY RUSSIA’S POSEIDON UNMANNED UNDERWATER DRONE IS A DOOMSDAY WEAPON?
Let's get started.

Amazing : The Russia’s Poseidon-underwater ICBM) can destroy enemy by generating a tsunami.
Russia has begun underwater tests of its Poseidon thermonuclear torpedo.

The Poseidon is an 80-foot-long nuclear-powered submersible robot that is essentially an underwater ICBM. It is designed to travel autonomously across thousands of miles, detonate outside an enemy coastal city, and destroy it by generating a tsunami.

"In the sea area protected from a potential enemy’s reconnaissance means, the underwater trials of the nuclear propulsion unit of the Poseidon drone are underway," an unnamed Russian defense official told the TASS news agency.

Putin presented Poseidon a nuclear-armed underwater dronePutin publicly announced Russia has been working on a nuclear-armed unmanned undersea vehicle. There have been a number of reports of both of these weapons being in development for years, but without any clear official confirmation. The craft, which Putin says has no official name as yet, but which observers have referred to as Kanyon and Status-6 since information about the system first leaked out in 2015, is a completely different approach to avoiding missile defenses. 
Launched from a submarine well off shore, the underwater drone then makes it ways to the target area, avoiding any sensor networks or other defenses, before detonating its reportedly dirty warhead, causing significant immediate damage and lasting contamination. A computer generated presentation about the vehicle shows a modified Oscar II class submarine carrying a pair of the unmanned submarines in a special forward compartment.
Putin suggest the drone would be "100 times smaller" than traditional submarines and therefore be especially difficult to detect. It would also be able to travel at "extreme depths" and at speeds that "greatly exceeds the speed of all submarines, up-to-date torpedoes and all types of high-speed surface ships,” making it even harder for an opponent to spot and intercept it before it reached the target area.
Previous reports, as well as accompanying video, suggest the weapons are large, though, which might necessitate a new, specialized mothership. The same video presentation paired with Putin's discussion of this system appeared to show a more conventional torpedo, but its not clear if this is supposed to be stand-in for the nuclear-armed drone or if that craft might launch those weapons itself once it gets closer to the target.
There is the suggestion that this unmanned undersea vehicle may have a nuclear powerplant, as well, which could conceivably allow submarine carrying it to launch it from almost anywhere in the world. The Russians appear to envision the system as a means of targeting task forces of surface warships – all of the computer-generated examples were clearly based on American designs – including aircraft carrier strike groups, as well as naval bases and ports.

Russia's "Poseidon" Nuclear Torpedo: Are We on the Verge of Nuclear War?

Russia Released The First Footage Of Poseidon Nuclear Torpedo
Russian Defense Ministry has released a video of the new Poseidon nuclear-tipped underwater complex, also called super-power nuclear torpedo.

The first footage showing the new nuclear-tipped autonomous underwater complex at the test facility. The new video shows a static test of the sub, which is basically an enormous nuclear-capable torpedo.

Rudders of the large device and its propeller are moving while developers observe its performance. The most intriguing part of the drone submarine – its propeller – is blurred out.

The device is launched from a crewed submarine and travels to its target at high speeds deep underwater, which makes it nearly impossible to intercept, according to the Russian military.

“Unique characteristics of the Poseidon system will help the Navy to successfully combat aircraft carrier and strike groups of a potential adversary in any oceanic theater of war and destroy shore infrastructure facilities,” chief analyst of the General Staff, Admiral Igor Katasonov, has said.

Also early, Russian military analyst Leonid Nersisyan noted that the idea of developing giant torpedoes with a nuclear propulsion system and a powerful nuclear-tipped charge appeared in the USSR back in the 1950s, the project was called the T-15 and was actively promoted by A.D. Sakharov.

However, modern technologies have made the old concept realizable – the scheme of the “Status-6” unmanned underwater vehicle with a nuclear propulsion system was “accidentally” released at Russian media in 2015. Since then, there has been virtually no official information on it, but there have been a lot of rumors about whether the project is real or it’s just some kind of concept. Recently, the existence of the project was recognized in the report of the US Department of Defence. Now it was officially confirmed by Russian military officials.

Previously the media reported the range of new Poseidon underwater complex will be more up 10,000 km, a depth of 1 km and a cruising speed of up to 185 km/h.

The first nuclear test fired at Novaya Zemlya was an underwater test of the RDS-9 warhead deployed on the 53-58 (T-5) torpedo. Over 30 ships were positioned at distances ranging from 300m to 1.6Km. Among the ships were four destroyers, three submarines, minesweepers and seaplanes. Over 500 goats and sheep, 100 dogs, and other animals were on board the ships. Only one ship was sunk by the explosion, a destroyer less than 300 m from the explosion.
