Two megatons. The media revealed the characteristics of the underwater drone

The Poseidon unmanned underwater vehicle created in Russia will be able to carry a nuclear warhead with a capacity of up to two megatons to destroy enemy naval bases, reports TASS, citing a source in the military-industrial complex.

On the “torpedo” of the multi-purpose marine system “Poseidon”, it will be possible to install various nuclear charges, the maximum power will have a monoblock thermonuclear warhead similar to the “Avagard” charge - up to two megatons in TNT equivalent

- source said

According to him, in nuclear equipment, the device will be “designed primarily to destroy the fortified naval bases of a potential enemy” and will be able to reach the target at an intercontinental distance at a depth of more than one kilometer at speeds up to 130 km / h.

As previously reported, the Poseidon will enter the Navy’s combat strength under the current weapons program for the 2018-2027 years, its carrier will be a new specialized submarine being built at Sevmash.

2 megatons is somehow not very much, but not very small.

its carrier will be a new specialized submarine under construction at Sevmash.

And here I think the carrier can be, with some refinement, almost any submarine or surface ship.

Belgorod is an old project, all the same at the heart of 949A. It is rather a carrier of deep-sea atomic stations (AGS) ala Losharik and others like them. It will be completed to replace the BS-136 "Orenburg", which is high time to cut into needles.

Not at all a fact. In addition, subsequent Ash-M can adapt to the use of such a torpedo. After all, on PIKE-B there were Grenades with YABCH.

According to the classification, everything that is larger than 1Mt goes like an extra-large power, so this is quite a lot to itself. There, only the diameter of the fireball is more than 2000 m., The diameter of the cloud is more than 22 km. This is a ground explosion, underwater (surface) its "charms".
And interestingly, the option of launching from the shore is being considered? In terms of reliability and security, it would not be bad.

It is important to conduct exercises with this thing more often, as follows:

The US destroyer entered the Black Sea - a boat surfaced near the US coast, said it’s armed with Poseidon,

did something else bad - surfaced again, at Florida


And it’s always so that, like Pavlov’s dog, a reflex is worked out - a low-key ... ..

"Intended primarily for the destruction of the fortified naval bases of a potential enemy"

I have a very indirect relationship to the sea. Apparently, therefore, I don’t understand what the destruction of the Navy pair will bring, when the entire fleet of adversaries will already be at sea near our shores. This is if at face value take the stated goals. I think that their task is to "wash off" the western coast of the United States.

Most of the US industrial infrastructure is located off the coast. This is the idea of ​​the same Status-6. Destroyed all coastal infrastructure and the United States suffers unacceptable losses.
The beauty of the Status is that it is effective not only against the United States but also against the EU, China, Canada, etc. ... and against us it is ineffective, since our industry is mostly in the depths of the mainland.
I think Poseidon will also carry different warheads ... maybe a non-nuclear warhead, but with a good warhead. If it is necessary to sink the ship. Or with a super powerful nuclear warhead at 50 megatons, in case the United States cut through at the end.
2 megatons is quite a good torpedo for itself, capable of not only washing off the base, but also sowing the AUG in bulk.

[Yaro Polk]

Megatonna (abbreviated as Mt), depending on the context, can mean: A unit of mass equal to 106 tons or 109 kg. A unit of energy equal to 4,184 × 1015 J. It is defined as the amount of energy released during the detonation of 1 million tons of trinitrotoluene (TNT)

There is nowhere to recharge, refuel, repair the adversary. There is no place to trade either. Plus, no fleet can leave the base as part of 100% - some ships are always under repair, maintenance, and these ships will also never be able to go to sea never.

[Fedor egoist]

You can’t wash off the coast with a couple of megatons, perhaps the city. So, if power is not being cunning in a smaller direction, then only the cobalt version.
For Americans and especially those living nearby, an option with 50-100Mt, but without a cobalt shell, would be preferable. And so - both coasts will glow for hundreds of years. Perhaps part of the cobalt with the Gulf Stream will sail to Europe.

Or in a tectonic fault, to smell near the adversary, as an option.

[Abram]

the article deals specifically with the carrier of high-power thermonuclear weapons for the destruction of naval bases. Based on this, I concluded that either this function is redundant, or missile defense is a much more serious opponent. And you can fantasize about other uses for a long time.

Quote: Abram

Hmm, but no one, except some here, suffers from hatred. The US is supposed to be a serious adversary. And how can circumstances arise in the event of a conflict, no one is 100% able to predict. So the guaranteed defeat of one or another type of weapon is laid.

[voyaka uh]

In general, you were not mistaken. These "mega" projects are a kind of indirect self-recognition of Russia in self-doubt. Acknowledgment of the increasing lag in technology from a group of developed countries and a recognition of the inability to bridge this gap in the future.
Unlike China, which found the strength to make a national effort - a common technological breakthrough, Russia hopes for super-weapons that compensate for the technical backlog. And this is sad, because it will lead to reciprocal (and more technological) “anti-Poseidons,” which will further widen the gap.

[Mountain shooter]

Two megatons is New York nafig. In an explosion underwater - in the state of New Jersey, the wave will ride ...

[Kostadinov]

The intercontinental range means that it can be launched from the coast.

[Lerych]

I don’t think that Poseidon’s attack on the coast is the primary task. There are other means. You can’t just shoot from the Pacific, Arctic, Atlantic Ocean, from the Black and Mediterranean Sea in Russia. BLL for the global destruction of the fleet of the restless "partner".

[NEXUS]

Quote: Lerych

I don’t think that Poseidon’s attack on the coast is the primary task.

Poseidon is just a more guaranteed argument, because you can’t build a missile defense system at a depth of 1000 meters.

[Imobile]

It is very cool. It can go at low speed, and if you replace the iron with metal and plastic, it will be invisible. In addition, it will go along the magnetic fields of the earth and fall approximately, with a small error. The question is the price of 1000 pieces and we are not victorious (against the USA) This is really a real weapon against which it is almost impossible to defend itself, and not fairy tales about electronic warfare (they are also needed) that turn off ships.

[Lerych]

Why with a "small margin of error"? From a depth of one km at this speed, you can very accurately get to the desired point of the doomed aircraft carrier. What will he stop her with depth bombs?

[Imobile]

It is necessary to put sensors to determine that it is an aircraft carrier. It is expensive and ineffective. I'm talking about the passive regime for destroying the coastline, without support the aircraft carrier will somehow collapse.

[Lerych]

I do not think that sensors and other are not provided for in Poseidon. It makes no sense to smash the bank with such a thing. That is the Strategic Missile Forces. If you run from Vladik to California, how much will it creep? The war will end. All this is done to suppress the advantage in AUG. There, most likely, everything is imprisoned for this.

Precisely, cheaper than 2 for 100Mt than 100 for 2Mt, because the main cost of the warheads is in the plutonium initiator, and in a three-stage 100Mt scheme they need only 3.

[_Ugene_]

will be able to go to the target at an intercontinental range at a depth of more than one kilometer at a speed of up to 130 km / h

the hunch bent, it’s on what engine can he do that? 70 knots under water and even at an intercontinental range, and a depth of more than a kilometer, it somehow sounds fantastic

[Lerych]

Well, the engine is a compact nuclear installation. This is already voiced. Speed ​​- Flurry moves much faster. So they crossed. Depths added. Brains added. It turned out Poseidon. Our World - 1 and World - 2 for Cameron Titanic drowned shot. There is technology. Why not doubt it?

[_Ugene_]

A flurry in a cloud of gas flies rather than floats; this is impossible at the intercontinental range. And with an ordinary screw of 70 knots, it should be in the form of an ordinary torpedo - long and thin.

[Vadim237]

On ordinary screw travel, to reduce resistance - the nose will be pointed.

[Clueless]

and what is fiction then? Power to one place :)) The main thing is that this power does not go into the pipe

[Clueless]

Who has acquaintances in the ministry, I throw an idea;)
Let this thing tow nuclear explosive bombs, and discard them where necessary, before use. Such a train, current under water - it will be more economical than detonating a torpedo with a nuclear installation

[Svetlana]

Quote: Bad

Let this thing tow nuclear explosive bombs, and dump them where necessary, before use

And on towed land mines, position the rudders along the pitch and yaw - so that the train does not catch on the snags when passing near the bottom. Management of towed landmines - along the Kevlar cable with fiber optic lines.

[Svetlana]

Options for power supply for towed thermonuclear explosive bombs:
- from Poseidon via flexible conductive cable,
- hydroturbines - electric generators and rechargeable rechargeable uninterruptible power supplies (UPS) located on towed land mines.
- through a rigid automatic coupler by means of hermetic docking units, fixed to the HE mines with pyro bolts.
A towed train is assembled, alternately hooking up nuclear mines with rear propellers to the automatic coupling unit.
After delivering landmines to specified points on the sea, Poseidon can return to the base for the next portion of landmines.

[aKtoR]

I would like to note that the submarine "Khabarovsk" (as noted in the booklet long ago - the carrier 6 SPA (self-propelled underwater vehicles)), most likely, will not be included in the GU GU (Main Directorate of Deep-Water Research), since there were no representatives on its tab this control (earlier on the tab of their boats were present).

In a report to the President of the Russian Federation, the head of Sevmash called this submarine strategic, although it, like the submarine "Ash" belong to the multi-purpose. Consequently, the submarine "Khabarovsk" can solve strategic problems of destruction of enemy targets, like SSBNs with SLBMs. Only her spa is not included in the overall offset for START-3.

Above was the message that such systems can be put on any submarine. Unfortunately, this is not the case. To install a spa equipped with a special warhead, a global rework of existing submarines is required, which is not economically viable. It is easier to build new specialized boats, with an increased depth of immersion (up to 1200м), on which the submarine can detect aircraft carriers at a distance of 1000-2000 km. To detect large AUG ships at such distances, large volumes will be required for the installation of fundamentally new equipment. Of course, a significant number of spas must be equipped with conventional warheads. And to hit naval bases and industrial centers is not necessarily precisely with AUG. This can be done in the event of the start of World War 3, launching strategic SPAs from bases near our territory

oh sorry not 200

[aleks.29ru]

The idea of ​​Poseidon is completely crazy. In the style of the prodigy “Weapon of Retribution”.
Why not dream about bacteriological weapons? Or make earthquakes?
Blow up a large volcano so that the whole planet is covered in ash? Deprive Earth of the atmosphere? Poison the oceans?
"Poseidon" - finely somehow. Slightly mischief the adversary.

[Cook]

You somehow lose sight of the fact that Poseidon is a deterrent, not an attack. The adversary should clearly be aware that in the case of sudden movements, no one will have a chance. Americans regularly assess the potential damage from a mutual attack while it is deemed unacceptable. As for small, not small, so port-to-port strife. Imagine the effect, for example, of the fact that the naval base in Norfolk will be destroyed, with the command of the fleet, shipyards, etc. So there is nothing delusional in this idea, given the fact that the factor of surprise. And let them come up with countermeasures, losing time and money on this.

[Old26]

Everything in this world is passing ....
So our "superdivays" began to gradually dry out. It all started with the infamous “Status-6”. There were 100 megatons and 100 knots of stroke, a dyne of 20 with a penny meters and a diameter of 1,6 meters
Now Poseidon has already shrunk to 2 Mt and 70 knots. I won’t be surprised that by the time he is put on duty it will become clear that he has a speed of 50 angles, an immersion depth of 300-500 meters, and a nuclear warhead of 5 kilotons, not more. The dimensions and diameter will dry out, most likely to standard torpedo sizes ......

It is possible, for example, to compensate for the ANN error by placing autonomous beacons powered by RTGs along the trajectory of the seabed at the bottom of the sea. These beacons are able to respond with sounds only to a given code sequence of sonar impulses located on Poseidon. Taking the response from these underwater lighthouses, Poseidon will compensate for the error of its ANN. It is assumed that the coordinates of the locations of the underwater lighthouses are known to Poseidon.

A bottom map can be made up, digital. But the bottom is not something frozen like a stone. Bottom changes will go on and on. This is the first.
