Russia tests Status-6 “Poseidon” nuclear torpedo.

Status-6 or “Poseidon” is a nuclear torpedo with a liquid metal reactor. The speed of that system is at least 100 knots. That is about 186 km/h. The torpedo uses GLONASS and AI navigation systems to position it in the right position. If that system uses the 100 megaton warhead. The pressure wave can destroy the entire submarine fleet that patrols the ocean. The fact is that North Korea introduced similar nuclear torpedoes, unmanned underwater vehicles, UUV, in its military parade. 

The fact is that legitimation of those drones, or underwater nuclear missiles based on the idea of the mutual assured destruction, MAD doctrine. That means an attack against another state that has nuclear weapons. Causes destruction to both participants. This explains those weapons' huge warheads. If something destroys Russian nuclear weapons, one surviving Poseidon torpedo makes a counterstrike possible. There can also possible that there are nuclear torpedoes that look like regular torpedoes. Those small systems might have a nuclear warhead of about 1-15 kt. size.  

Those systems can have RTG, a Radioisotope thermoelectric generator that gives them an unlimited operational range. Same way as the nuclear reactor gives Poseidon an unlimited operational time. The torpedo can be launched from submarines, ships, or it can be released from a military harbour. That makes them hard targets for defenders. 

There have been. Some kind of thoughts. There are also submarine-sized fully automated underwater drones. That can involve three or four internally explodable tsar bombs, each of which is about 50 mt. size. Poseidon torpedo is about 20 meters long, but it can have a warhead. Sized 100 mt. The system uses a supercavitation propeller. In that system, the active system pumps water through the propeller.

That allows the faster rotation speed for that system. The active pumping system prevents the water from boiling. And that limits the bubble formation. The active system denies the possibility that the main propeller forms a bubble around it. If the propeller forms that bubble, it loses its ability to move the craft. The active system pumps water from the propeller sides between its wings. That denies the bubble formation around the propeller. 

Status-6 Oceanic multipurpose system, also known as Kanyon or Poseidon. 

The purpose of that torpedo is to create a giant tsunami that destroys other ships and causes terrible destruction along the entire coastline. The new torpedo tells something about the despair in the Russian government. Putin says that this torpedo is unstoppable. That system is fast and equipped with nuclear explosives and a liquid metal reactor. And if something damages those torpedoes. 

That can cause nuclear pollution to spread all over the ocean. If that system detonates itself in some trenches, the pressure wave travels in those trenches over two or three years. With a force that destroys a submarine. If the Poseidon torpedo detonates, most of the life in the ocean will be swept off. The reason why Putin and his government create that kind of weapons is that they can cause very big destruction. Only one of those high-yield nuclear weapons can destroy a large area. 

And if one of them can avoid defense, that causes very large destruction. Those weapons are meant to cause fear. They are so-called mutual assured destruction, MAD weapons. If something attacks Russia, only one of those nuclear torpedoes is needed to destroy a large number of targets using only one warhead. And that gives the frightening weapon into the hands of Putin. If Putin releases those “Poseidon” torpedoes into the oceans, the defender must find all of them. If one of them detonates, the destruction is huge.
