The Pentagon plans to equip the new destroyer in 2018 with a railgun

Work on the "futuristic" weapons in the United States is going well, so the railgun, capable of accelerating the projectile to a speed of 7 times the speed of sound, is planned to be installed on the newest destroyer earlier than expected - in 2018 g, leads Gearmix an article published on the resource abcnews.go.com.

“The initial plan was to test the railgun on high-speed vessels in 2016, but according to rumors, the US Navy is already building a working copy that can be installed on the coast guard ship Lyndon. B. Johnson. This ship, the last of the three Zumwalt class destroyers, will be the perfect challenger because its Rolls Royce turbines produce 78 megawatts, which is more than enough for an electromagnetic weapon, ”the publication says.

“The destroyers Zumwalt are intended for strikes against targets on land, which is also excellent for the railgun,” the author believes.

“The shells have so much kinetic energy that they don’t need a large explosive charge,” he writes. “This, in turn, allows them to replace missiles for only a small part of their cost.”



The article notes that “if the railgun is placed on the destroyer Lyndon B. Johnson, which is to be put into service in 2018, it will replace the front 155-mm cannon firing missiles.”

As Pete Fanta, the head of the actions on land in the US Navy, said, "although this is a new type of weapon, the fleet is quite sure of it." “It is currently being created; it is no longer science fiction,” he added.

According to Stanislavsky - "I do not believe" !!
I do not have a technical education, but in my opinion in a popular mechanics article was that the railgun is a very peculiar weapon from the point of view of physics and that 20-30 years is needed for improvements and tests. correct who is friends with physics, if not right

according to Lavrov "D ... b ..."

Give Trump to the presidency, we’d better trade than make plans for total and mutual nuclear armageddon.

"It has always seemed to me that Russia and the United States should be able to work well with each other to defeat terrorism and restore world peace, not to mention trade and other benefits arising from mutual respect."

In vain. This can be described in one word - THING.

This is a promising weapon, it makes sense to develop such on a par with a chemical laser. The weapon of the future. In the process of testing, use, application, any technology gets a compact portable look, and you get an excellent weapon and advantage. Oh, thing.

Pulse electrode mass accelerator, Lorentz force works wonders. Science, her mother.

Plus, roughly calculate the increase in required energy, taking into account promising developments to reduce energy consumption ...

You decide that you need a reduction in size, or given away?

If you want ICE with a fist - so they are full of modelism. And considerable capacities.
And there are even turbines. and also with a couple of fists.
Progress?

[Muvka]

It is the size that interests. After all, the railgun is a sore subject. So, there is no ICE the size of a fist and power, as written above, 33 hp Because there are laws of physics. And with the railgun the same trouble will be. Because we need huge capacitors that need to accumulate a charge, parallel to each other, in order to give it simultaneously then. And so in the tank we will never see this miracle. That's all I wanted to say :)

[Makarov]

everything rests as usual on materials - there will be the main components of the internal combustion engine from some superalloy of plastic, ceramics, tungsten (this is an example))) and that's it ...

Nobody posed such a direct statement of the problem.
There was no need yet.
Now with the overdevelopment of unmanned robotics, all sorts of drones, minimizing their size and increasing their characteristics, etc. - begins the development of ultra-small engines.
But look at the engines for modelers.
Here is the 2002 technology of the year (when drones still didn't smell).
Four Stroke RCV 91-CD engine, fully stocked.
The volume of the cylinder 15 cubes - 2 HP. Weight is only 700 grams.
Just at that time it was no longer necessary.
Now the demand will be.
In addition to high-altitude drones of low noise and slow, there will certainly be the development of low-altitude and ultra-fast.
Required.
And here we will see 10ls on 15 cubes.
those. 100ls on 150 cubes.

They used to say that too. that with 1 liter it is theoretically impossible to remove more than 100 hp.
50 years have passed and the world has changed.

This is a promising weapon, it makes sense to develop such on a par with a chemical laser.

How to say. Effective over short distances, in a marine format. Purely in the same science, through the upper point of the ballistic curve, kinetic energy falls with the terrible power of engineering. The same thing with a chemical laser, the efficiency of which, makes you just proud that you have it. But if you don’t have it, then you didn’t become weaker from it. It’s like the laces on the shoes, everyone has green, but someone has black ones, which makes him no better than others.

Quote: Asadullah

How to say.

... well, ours don’t sleep either ... tea isn’t basting, cabbage soup ... 7 minutes of video ... very intelligible and detailed, especially when mentioned, not only kinetic energy, but also an electromagnetic pulse ... ... appreciate the beauty of the Russian engineering answer, especially interesting with 3,54 ...

[Asadullah]

not only kinetic energy, but also electromagnetic impulse

So I'm talking about the same thing! An electromagnetic pulse (or some other) can accelerate the object to such speeds when the kinetic energy of the object increases geometrically. It is this energy, in theory, that must destroy the obstacles to the object. But the fact is that after exposure to an impulse, a flying projectile every microsecond has to take thermodynamic barriers in which it consumes this kinetic energy. In order to save it, it is necessary to create a vacuum or plasma tunnel before the projectile moves. In this case, the energy will not be wasted. Ten kilometers per second does not mean that the object was ten kilometers from the start point in a second, it means that it will fly one hundred and two hundred meters at that speed, and then the speed and kinetic energy will decrease exponentially, and after ten km , the disc, which until then was a shell, will plop with a bang on what bunker, or break the head of an unlucky onlooker. For the effectiveness of such weapons, this same, mentioned tunnel, or constant recharge in the direction of the missile type is needed. But if you create such a tunnel, then these electromagnetic bandages fuck are not needed, because any bullet that was pushed by a banal powder discharge will fly on it as much as Earth's gravity allows, while preserving the initial energy. That is, you hammer a nail with one blow of a hammer from a distance of forty centimeters, and now imagine you threw a hammer into this plasma tunnel in Moscow, and a nail was hammered in Washington, because all the kinetic energy of the hammer was saved.

[abrakadabre]

and after ten km, the blank, which had previously been a shell, would plop with a bang on what bunker, or break the head of an unlucky onlooker.

or, which is very likely to burn out as a meteorite. Meteorites have a higher speed, but they also move in the most discharged layers of the atmosphere. While the shell of such a gun flies in its densest part.

A meteorite enters the atmosphere at a speed of under 20 km \ s, it is at least 10 times more, plus compare the area of ​​contact. The meteorite does not burn, there is an ablation that they can fight with, the abelion coating of the descent vehicles is an example of this.

... so, to understand the breadth of the issue, Comrades, I understand that it’s obscene, but alas:

A group of scientists from the Samara branch of the Physics Institute. P.N. Lebedeva RAS (Siberian Branch of the Lebedev Physical Institute) obtained revolutionary data in the field of modeling shock waves in a nonequilibrium gas medium, which will make a significant contribution to the development of new science - plasma aerodynamics.

.. and further, in the same obscene language ...

We showed for the first time on simple models that in a nonequilibrium medium the structure of the shock wave can indeed differ greatly from the equilibrium one. Four types of stationary waves were obtained: (1) shock waves with increasing density and pressure behind the discontinuity, (2) waves with decreasing these values, (3) in the form of an autowave pulse, and (4) in the form of a detonation type autowave with a nonzero asymptote. It is shown that the evolution of small-amplitude waves can be described for all these different models of nonequilibrium heat-generating medium by a single nonlinear equation "

... that is, there is a formula that describes the interaction of air and plasma ... Kamrad Asadulla, do you understand what this is about? ...

I have the usefulness of this weapon is very doubtful - it’s more like mastering the Pentagon’s funds and the lobbyists’s good work on knocking out these very tools, including through a beautiful picture. An uncontrolled kinetic projectile, essentially an enlarged analogue of a tank BPS, is ineffective against a surface fleet - that's why the Americans plan to use it only on land, where the projectile has the ability to transmit all the kinetic energy of the target. A narrow-necked weapon is obtained - shooting at coastal remote targets, because near (up to 50-60 km) you can work with the usual on-board automatic art. installations. Long-range shooting from the railgun will suffer from a progressive drop in accuracy, it will be necessary to adjust and shoot for a long time - a greater distance than with ordinary artillery fire, sea rolling. The operability of the gun depends on the main control system of the carrier. I don’t know ... This is all unconvincing - in terms of efficiency and cost. Although the pictures can certainly be taken amazing, which I’m sure will be done in the future, which is unlikely to affect the combat effectiveness.

Yes, why burn something? No one will use nuclear weapons, for the answer will be fatal.

If you use this torpedo, then the USA will use Trident-2 D5 for you from all Ohio-class submarines that float around the oceans, they will have enough time for this.

Moreover, it can be used both against terrorists and against any state, this is not a doomsday weapon. It does not have global destructive consequences.

And what you are talking about, Status-6, this thing is intended to destroy the naval bases and important enemy economic facilities in the coastal area and inflict guaranteed unacceptable damage to the country's territory by creating zones of extensive radioactive contamination.

It remains to be seen whether they will be able to bring it to mind, but you are already sprinkling ashes on your head and are upset that it is not with us. Remind you how much howling was about SDI? And the Boeing laser? In my opinion, he should have entered service ten years ago. When thousands of drones were riveted in America, they also predicted the future and tried to say that everything, the Americans would break everyone with drones. As a result, it turned out that these drones only work against banana republics, and even then not always. If suddenly the banana republic digs out the Soviet electronic warfare complex half a century ago, then the drones for some reason begin to fall and their whole future ends there. How many more billions the Americans will cut into "weapons of the future" is purple to me. But there are laws of physics and harsh reality. And before sprinkling ashes on their heads, it would be necessary to try this weapon of the future on them.

Kindergarten, the second shift. If this gun was created in Russia, there would be a puppy screech at the VO for at least a year, where are the calibers.
The future is behind such weapons, and even if this particular project is not the most successful, the technological and engineering developments are simply colossal. This is a real HiTech, with all the consequences for the year, on the knee it can not be repeated.

It is also being developed in the Russian Federation, but in contrast to the United States, everything is not so open in our country and the results of the Komsomol are not reported.

[Cube123]

Look for the book, edited by Academician Velikhov 1983, "Space Weapons Security Dilemma." There are all this and railguns and lasers. With physics of processes and evaluations of capabilities and efficiency.

And on the railgun - here is the open information http://epizodsspace.narod.ru/bibl/valier/1-3a.html
For large calibers (which we will have to talk about later when evaluating the possibility of firing a cannon at the moon), according to Krantz, the following values ​​of air resistance (in atmospheres) take place:
a) Caliber of 10 cm, the shell in front and behind is chopped off perpendicularly.
b) Various frontal projectiles with a rounding radius of 3 calibers.
Velocity V in m/s * 400 800 1 200 2 000
W / F for projectile 1,58 6,85 15,64 43,80 175,6 1
W/F for round disc 2 8 18 50 200 1250

Those. for a projectile speed of 2 km / s, air resistance is thirty times greater than for 400 m / s. And for 4 km / s more than a hundred. For the atmosphere, the railgun is only an inefficient way to heat the air.

And so - you have a lot of errors in the text, but there is one fundamental error. You confuse a scientific breakthrough and the technology of its use.

Quote: _Vladislav_

The railgun is and Russia does not.
This is a fundamentally different level of technology. It is like quantum mechanics. New word.

1) The railgun in Russia IS. The Shatursky branch of the Joint Institute for High Temperatures of the Russian Academy of Sciences is engaged in these matters, and a working prototype of an electromagnetic gun (a projectile weighing 3 grams accelerates to 6,25 km / s)
2) Electromagnetic acceleration technologies have been used in the laboratories of the USSR / RF since the beginning of commercials from the 70s of the last century.
So this is not a "new word" or a "new level". There are no SCIENTIFIC problems for creating a combat railgun in the Russian Federation. And if there was a great desire, then by investing a bunch of money it would be possible to create an analogue of the American "railguns". From the point of view of science, that is, scientific theory, this problem has long been solved. Only one question - why translate it into hardware? :)
There is a HUGE amount of scientific developments that will never be implemented in metal. Just because having the opportunity to create some kind of technology does not mean the need to create it. For example, it is obvious that at the current level of technology it is impossible to create compact power supplies for lasers. Why, then, spend money on developing laser machines? After all, it is initially clear that until there is a power source, a normal device will not work. So with the railgun. We can create it. What for?
The point is precisely to implement "in metal" only those scientific developments, from which a sense will come out here and now and / or which will allow science to move on. If the topic is interesting, but now is not the time for it, it makes sense to either put it aside, or limit it to R&D at the laboratory level.

Russia is engaged in hypersonic weapons (and this is really a whole set of technologies of the future - controlling hypersonic flight alone is an extremely difficult task, which nevertheless must be solved, because without this, super-speed flights will never be mastered). Russia is engaged in electronic warfare (and here, according to a very widespread opinion, the Russian Federation overtook the United States, although the USSR lagged behind). Russia has taken up electromagnetic catapults (and this is a very dual-use technology, as it can be used to transport goods) and much more.

The Law of Lorentz was described in 1892 and even then, theoretically, with its help it was possible to move objects. If in 1970, 46 years ago, there was already the first working railgun when in theory it was possible? In the First World? In the 50s?

Quote: Andrey from Chelyabinsk

What for?

This is an example of the fact that scientifically and theoretically we can do a lot of things, but putting all this into practice is already completely different.

Quote: Andrey from Chelyabinsk

How many?

Let's just say, for the development of 28mn technologies, the state gave 1.6 billion rubles, and it was immediately said that it was a drop in the bucket. What do you think, how much did you spend 65mn crystals to create the technology, if as a result they scored and bought the PLANT right away, putting money into architecture. And before that there was a catch-up of 90mn. I think the state’s investments there in the tens of billions of rubles. Every time Western companies invest at least $ 5 billion in the creation of a new generation processor. So calculate how much money you need to make up for the backlog, since it’s almost impossible to jump into 12nm crystals immediately. That was 90nm, 65nm, now 28 are being prepared. By the way, they mastered them in Russia, but, ABOUT MIRACLE, on Western equipment. Crystals are expensive to grow, and creating processors is cheaper. The result has its own Elbrus, which actually has a native architecture, but the crystals are created on Western equipment, according to their technologies.

As for the UAV, back in 2010, before serious money was spent on it, they wrote about 6 billion rubles spent in vain. Moe said this, I can look for a quote if you don't believe it. After that, Transas allocated 2 billion for the development of the UAV, where is it? Design Bureau "Sokol" received 1 billion. This is all in 2011-2012, the first tests were promised in 2014. It's 2016. In 2012-2013, about 4 billion rubles were distributed for this. Whoever thinks there is no open data, but at least $ 1 billion has been invested in it over the past 5-6 years. Where are the results?
IAI spent $ 2011 million on R&D in 120. If they were given at least a lard, a line of small, medium and heavy UAVs, from scratch, would have been created in a couple of years. And the problem is not only the theft of funds, but also the lag, which is very difficult and expensive to catch up.
Z.Y
Lockheed Martin Costs for the whole R&D in 2011 - $ 400 million, or 13 billion rubles.

This is the difference between high technology. You can steal Volvo documents, build a factory and start riveting cars, China is doing this. But if you want a real high-tech production, you need to invest time and money in it. It is not for nothing that China started up mad dough on high-tech R&D. They understand that they are dependent on Western technologies, and it will take about 10 years to catch up. And the people here write this "everything has been known for a long time", "Even in the USSR they shot at the stands", it's not a problem to create from scratch. Optimists

The point is that these "new technologies" are over a hundred years old. The return to them is due to the lack of fundamental scientific breakthroughs. In military affairs, and in all matters of the world, this will be after the discovery of the method of creating a plasma tunnel in the lower layers of the atmosphere.

This is just not a question, the first question is target designation and rate of fire. The second is how effective it will be to throw crowbars from tungsten, with a kilo of explosives in the rear. After all, the effectiveness of this contraption is directly proportional to each gram of projectile mass. For example, a shell weighing half a ton, it is necessary to throw it from the installation, which can barely fit on an aircraft carrier. Here they follow the fashion of the latest American military concept, which suspects that after a two-week war with smart bombs and shells, the United States is bankrupt.

In your opinion, the Zumwalt was changed for a railgun in the hope that it would be lucky and enough? To abum? There are 78 megawatts, the railgun, as a result, when they reach the declared 32MJ, 25-30 megawatts will be needed, which were originally taken into account during development.

1) By accuracy of guidance - since the projectile is actually a large bullet, the electronic warfare will hit him on the drum, and will be guided by ship targeting equipment, the projectile is not adjustable.
2) By detection, this is extremely difficult, because the projectile does not have a GOS, and has an extremely high speed (well, according to the theory).
But the rest is very sad.
1) The recharge time will, it seems to me, be very long, since a huge amount of energy will be required. An alternative way is to use replaceable power sources of ultrahigh energy intensity (batteries, roughly speaking, replace cartridges). But at the current level of technology, this is impossible, such sources do not exist, and most likely will not appear in the foreseeable future.
2) The affected area, in my humble opinion, will not be too large. But if it does, it will not seem enough. Therefore, the priority tasks for the mass use of railguns will be, firstly, the search for sources of the necessary amount of energy (now only serious nuclear reactors in large ships can give this out, and even then I have big doubts about how they will give out the necessary peak power without temporarily shutting off the power supply to the rest of the vessel, perhaps a certain amount of accumulating devices powered by a nuclear power plant are crammed closer to the bottom). And secondly, the development of aiming systems. respectfully

[abrakadabre]

When flying in dense layers of the atmosphere at cosmic speeds, the passage channel will glow on the radar and in thermal sensors very much. For there is sharp and strong ionization. In fact, the projectile will create a plasma channel.

[Jack-b]

Quote: Observer 33

In this case, the projectile should not conduct electricity

In my opinion, it is just the shell that should conduct electricity. It is the current passing through it that pushes it out of the railgun. Recently, either on a hub, or on a github there was an article about how simple American guys assembled a small railgun and what problems they encountered. From my point of view, all problems are solved except one. A railgun is two rails between which a projectile is clamped. A small impulse is given to it (for example, with compressed air) and a current is introduced through it. Then Lawrence’s strength (I’m not a physicist and I don’t understand what it is - don’t ask :)) pushes the projectile. In this case, the projectile moves between the rails, is sandwiched between them and the currents pass very large (in fact, this is a short circuit). Naturally, under these conditions, at the point of contact, the projectile heats up literally until the metal melts. First, the shell itself is losing shape. Secondly, this metal is deposited on the rails, changing the channel geometry accordingly. For a toy railgun it doesn’t give a damn. And for guns firing for tens of kilometers, this is fraught with a loss of accuracy in my opinion. That's just curious how they solved this problem?

[abrakadabre]

A little bit wrong. As long as the projectile moves between the rails, nothing like this will happen. Will be at the moment of leaving the "trunk". That is, when the contact with the rails is broken. This sparking is known to everyone, as in a conventional electric switch. Only very powerful. For example, in large automatic circuit breakers at electrical substations, this phenomenon is carefully combated. Those who want to dive into the topic are looking for and reading about closing / opening currents.

[Jack-b]

Well, as if simple American guys who had assembled the railgun, they say that the remains of the shell are growing on the rails. I see no reason why they would lie. Here is a link to the article:

Likbez: for a pure railgun the projectile cannot be non-conductive, otherwise it simply will not accelerate in an electromagnetic field. Yes, there are shells made of non-conductive materials, but either, in one case, a highly conductive ionized gas is placed behind such a shell, or, in the other case, an arc discharge is ignited behind the back of a non-conductive shell, the back of the shell intensively evaporates, and it moves reactive method (as in a conventional gun).

It really has characteristics for all parameters not worse? And I mean really by all parameters... Because if it turns out that its striking power is a hundred times greater, the cost of a shot is ten times less, the rate of fire is three times higher, but the accuracy is three hundred times worse, then does it need such accuracy?

- It all depends on the tasks set and the capabilities of the weapon itself based on this principle. No matter how it turns out that these toys will appear on American satellites, and with impunity they will shoot Russian and Chinese launchers for ICBMs from orbit with precise direct shots. Then the American missile defense system will be a little easier - it will only be necessary to fight against launches from mobile complexes. Well, the range of mobile platforms is still more modest (excluding nuclear submarines, perhaps). This, of course, is still fantastic. But here's the problem ... American Tesla electric vehicles are already driving in Russian cities. But even ten years ago it seemed absolutely impossible, or a matter of a very distant future. But no. It turns out that the future was not so distant. As if it did not work out the same with laser / rail weapons. Nuclear weapons help Russia only as long as there are no guarantees that they cannot be used. And laser / rail weapons can be such a guarantee. Technology. You can't be inferior in technology.

What can we say about shooting hundreds of kilometers from orbit from a satellite flying at a speed of several kilometers per second. And secondly, for this railgun into orbit it is still necessary to pull out the generator. But thirdly, with such parameters of the shot, each time you have to adjust the orbit.

Once again, for the gifted. When the railgun is donated, the energy is spent on rails rapping, perpendicular to the movement of the projectile. This does not violate the law of conservation of momentum, instead of giving back, the energy is extinguished differently. Look at the attachment to the floor and compare with ground artillery. If all the bestowal was back, with such an impulse, it would vomit everything to hell. In addition, the recoil force is inversely proportional to the pulse arrival time. In conventional artillery, an explosion occurs and the impulse is transmitted to the projectile in a split second. In reilgan, acceleration occurs relatively slowly.

1. Pull the power source with the necessary total power. Moreover, so that he gives it out instantly. All such sources are sooo bulky and massive. In the coming years, a hundred is fantastic.
2. For kinetic defeat (direct hit of such a small projectile), you will have to consider so many parameters that the idea is very doubtful. Atmospheric fluctuations alone during the passage of this man-made meteorite, and even in most cases at a very oblique angle ... Either burn out in the atmosphere, or deviate by several meters and the target is no longer hit. You are embarrassed to calculate.
3. Correct the orbit will not have very much. Since the weight of a station capable of bullet will go so many hundreds of tons. If not for thousands.
4. A much bigger problem is the discharge of excess energy. After all, the installation cannot work with an efficiency of 100%. Together with the projectile, less than half the energy of the shot will fly away. The rest will go to heat. And we are talking about a lot of energy. In space vacuum, the issue of cooling is a very big technical problem. Because vacuum is the best thermal insulator possible. It is on Earth that you can put a radiator and blow it with air or (in the case of ships) sea water. In space, this does not work. And to the multi-cell system for generating energy for a shot, a no less multi-cell cooling system is added.

- Believe it or not, IT exists. Therefore, we will change the question: what does the Russian Federation have on this topic? I would very much like to BELIEVE the asymmetric answer every five times, according to the meager, more powerful.

I'm wondering.
everyone relies on the so-called asymmetric answer.
But have you ever thought that the so-called asymmetric answer is exactly the same weapon?
Just different.
And what is the same weapon - usually invented by all parties?
In response to one unique child prodigy, it is impossible to come up with another unique child prodigy that will defeat the first one and will be cheaper 5 times.
There will be two prodigies!

To me, these arguments, about asymmetric answers, remind me of a joke, about two cowboys who are for a dollar. got drunk on manure ...

They promise 7-10kg, 10 rounds per minute. Implement such a rate of fire or not. another question.

[Jack-b]

I would also like to hear the opinion of experts. Especially on the video. Firstly, if you look at the first shot, you can immediately see that the projectile starts to "sausage" when it leaves the barrel. It turns slightly, although the channel cross-section is rectangular and rotation of the projectile should not be given. Secondly, I do not understand the presence of a fiery explosion coming out of the barrel. After all, the shot is fired using "electricity". In theory, there should not be a powder explosion. Where does the explosion come from? Third, the second shot at the 13th second. IMHO this is an ordinary barrel, moreover a tank one - with a powder gas ejector. I understand correctly? In the fourth, if we compare the projectiles of different shots, it is not clear why in the first shot the projectile had rectangular shapes and did not open, and in subsequent shots it became round and a sub-caliber core appeared. Is there anyone who understands the topic who can comment?

[abrakadabre]

Secondly, I do not understand the presence of a fire explosion emerging from the barrel.

There are two reasons for the explosion at the cut of the trunk:
1. A giant spark from the huge currents of the circuit / opening. You have seen a similar little one many times in your life if you have ever seen a short circuit or when you turn off a normal household switch when it sparks.
2. Air heating during movement in a dense air medium of a body with cosmic velocity. If you have ever seen a meteor in your life, then this is it.

This flash is effective not only in the visible range. But in the infrared and in the radio range too.
Due to this outbreak, the "trunk" cut will have very high wear due to erosion. It will simply evaporate. If this is a problem for powerful switches in high-voltage substations, then the energy is even higher.

I was sure that it was because of the plasma after exiting the barrel, so the fire was behind the projectile. When a meteorite falls, it looks different.

Somehow

It doesn't look like an electric arc. Arc it must go from one rail to another. There is an explosion of volume. If you look at the shots of ordinary guns, there is a very similar picture. Which raises questions.

[Archon]

an ordinary railgun can assemble any home. and they just have a bigger size and eat more

[tilovaykrisa]

everything is fine with them, the current installation is already 5 years old as they just adapt it for the Navy, in 2018 they will put it on for a couple of years, they will drive it and adjust to the fleet then it will be working, it’s all about energy and high wear so it's just that they won’t bullet along the shore, you need to do something for her of course, of course, and you can quite a lot have money and you can buy a couple of expensive toys, but it doesn’t change anything at the root.

The United States tested a 21st century weapon - an electromagnetic railgun gun.

Which, thinly smiling, to Lavrov, as if by chance, Kerry said, carefully following the reaction of the head of the Russian Foreign Ministry.

“How interesting,” said Lavrov calmly. - And how does it work?

- Oh, this is the highest technology! - Kerry shone and brought to the tablet a colorful diagram in 3D. - Here are two rail-electrodes, and between them the mass of mass accelerated to great speed. Everything works on electricity. Firing range up to two hundred kilometers, a shell of ten kilograms! This is a real breakthrough! No one has any analogues. What a beautiful one!

“Beautiful,” agreed Lavrov. - And as for the analogues, you are mistaken. We have a railgun for a long time.

- Can not be! Cried Kerry.

“And I, John, will draw my scheme now, though not as beautiful as yours, but as I can.”

And Lavrov drew two parallel lines, between them drew several small squares, and from the small squares he drew a long dotted line, at the end of which he wrote "KHRYATSY !!!". I thought a little and attributed “DB”.

- What is it? - surprised Kerry, looking at the drawing.

“These are two rails, and between them is a military railway missile system with six Yars accelerated by two locomotives. Everything runs on fuel. The firing range is eleven thousand kilometers, each with warheads of three hundred kilotons. Railgun "Barguzin", as we call it. There’s even a song about him: "Hey Barguzin, move Yars - fly not far off." You can take the scheme, John - I’ll draw it for myself.

Kerry choked and through a cough asked Lavrov to write down the words of the song on the diagram.

[Trigger-Happy]

It is very interesting to look at the performance characteristics of this offspring. At what distance from the cannon does the speed of the disc fall to the speed of an ordinary cannon shell? ..... Somewhere in the news there was information that ours were also working on a railgun, but so far only in laboratory conditions. We can say with complete certainty only one thing - we can’t lag behind the Anglo-Saxons in armaments, it’s like death!

Here is the answer to Oleg Kaptsov - the railgun will penetrate any armor, and there is no doubt that it will be brought and put into service.

[33 Watcher]

Like the F-35? And where does it fight this super-weapon?

[Jack-b]

Damn, how many Americans, and not only them, had promising technologies about which there was no doubt. You remind about SOI?

[chunga-changa]

The railgun, by the way, was supposed to be one of the SDI elements - here it is, it works. SDI was not stopped for technological reasons, the United States achieved its goals in other ways. Anti-missiles, the Aegis system, chemical lasers, by the way, it's all from there, and it's all there.

[Mountain shooter]

Again twenty-five. Large-caliber sub-caliber ammunition, when fired at long distances, greatly "lose weight" due to heating in the atmosphere. The resistance of bodies in the atmosphere is proportional to the SQUARE OF SPEED! Railgun shells fly three times faster than BOPS. How much will such shells "lose weight" when passing through the dense layers of the atmosphere? And how will the aerodynamics "lead" them along the flight path - they are not stabilized by rotation. In general, striped-eared admirals have read a lot of science fiction. And they did poorly at school, or rather they teach physics very poorly at school. And for a long time.

[minus]

Judging by the video, the shells are precisely stabilized by rotation. It is interesting what the achievable rate of fire of such a gun is. Conducting rails will hellishly overheat. And their resource is not known. It is thought that after a couple of dozen shots they will be destroyed by plasma. An expensive toy will be) In addition, capacitors to this device will have a huge mass and cost

[Winnie76]

Resource barrel - allegedly achieved 1000 shots. But somehow it is doubtful ...

[abrakadabre]

I wonder what the achievable rate of fire of such a tool

What units do you need? In bucks per second?

[spech]

And they studied poorly at school, or rather, there they study physics very badly at school. And for a long time.

There is one more point that is always forgotten: with huge currents flowing during the discharge, EMR is generated (although not as powerful as in nuclear explosions, but nearby )

[voyaka uh]

"In general, striped-eared admirals have read a lot of science fiction.

Admirals are sitting at the reception of finished weapons. And come up with new weapons
specialists, starting with physicists. Physicists give engineers a fundamental
"good" to the beginning of work, without physicists, doctors of science, never begin.
In Russia, they said for a long time that missile missile defense "contradicts physics - you cannot hit a bullet with a bullet," and today the S-500 is being completed - that very "anti-scientific" missile defense.
So it is with powerful lasers, which also go against physics. Combat laser work
weapons resumed in Russia, pulled out of the closet interrupted development of the 80s.

[nazar_0753]

Getting a bullet into a bullet is really not an easy task. That is why anti-aircraft missiles are not equipped with a single kinetic blank, but produce an explosion near the target, forming a cloud of damaging elements. Well, only the Americans are trying to create missile defense against ballistic missiles, but so far it’s not clear whether

Count that both the Japanese and the Chinese are doing this. and Russians ...
and everyone is trying to get in.
Just because with the development of microelectronics this has become a truly solvable and computable task.
10 years ago they couldn’t, but now they can already.
And we must change ourselves after technology. rather than repeating the thoughts of 10-20 summer ago.

[abrakadabre]

Unlike a bullet, a missile is capable of actively maneuvering and has certain target sensors on board. Which greatly facilitates the task. And even in this case, the task is very difficult.

All this is of course interesting. But I have a few big BUT ...

The article notes that "if the railgun is placed on the destroyer Lyndon B. Johnson, ... then it will replace the front 155-mm gun firing rockets"

According to the idea, then this shell will be more effective? And due to what?

they don’t need a big explosive charge

So they will work like sub-caliber armor-piercing shells ... punching all right through causing minimal damage?
Will the rate of fire be high? Will the conders charge quickly? And protecting people from pulsed electromagnetic radiation is not a pound of raisins. I showed the fighters the operation of the microwave by the example of the radar - I took a 60 W lamp, put it on the ground 20-30 meters from the radar, and the operator turned on after 10 seconds. turned off the station ... Would you see the faces of the fighters when the light came on brightly. The soldiers who passed this experiment did not come close to the station later. And here there is only a ship - space is limited. And the impact on the projectile during the flight of the wind of rain and other misfortunes ... For long distances when firing with simple shells, we even did calculations according to special tables, before that we had weather preparation and NEVER said that we would hit the target the first time. It's impossible. And they mean they can?

Yes, what three times ??? The initial BOPS speed is M = 6, and here it is only M = 7. Nothing extraordinary. This is just advertising, no more. Designed for those who do not know that the Russian tank BOPS flies at a speed of just some 1800 m / s. Somehow this topic has already been raised, and then I also pointed out this in the comments.

The difference with OBPS is small - instead of a powder charge, the arrow will be accelerated to
high speed electricity.

This "new word" is one hundred years old at lunch. At least you went to Wikipedia for a start, before this nonsense about quantum mechanics and fundamentally different levels to carry?

Americans are engaged in image-building public relations, that’s all that the railgun currently means. And noodles with cranberries hang from your ears.

The railgun in its current form has a number of technological limitations that do not allow it to be used as a type of weapon.

Firstly, energy per shot. She needs a lot and fast. Huge drives are needed that can quickly give out and replenish energy. The current level of technology does not allow creating those with the required characteristics. What the Americans use allows us to talk about test shots, but not about military use.

Secondly, the material of the rail itself. There is no necessary material for today. Rails burn out after a dozen shots. Replacing the “barrel” after ten to twenty shots is the level of testing, but not of the finished product.

Thirdly, in order to fall into something at the range indicated in Amer’s PR, you need control electronics in a disc that is resistant to overload. There is no such today, this is a matter of the foreseeable, but future.

Americans can squeamish as much as they like about how technologically advanced they are, but for those who at least protect their ears from noodles with cranberry sauce, it’s clear that this is just screaming for PR.

A real combat railgun will appear no earlier than the specified limitations of available technologies are overcome.
