US's Ultra-Advanced Railgun Weapon Is Making All Others Obsolete 

Couldn’t you apply some maglev or magnetic containment elements to keep the projectile from touching anything physical after loading to create frictionless firing?

@@CharlesGaluski That's called a coil gun. And it's significantly more complex than railguns, needing a lot of electromagnetic coils powerful enough to accelerate a projectile quickly and timing mechanisms to make sure that once the projectile moves past a certain point the coil deactivates to make sure it doesn't slow the projectile down, as well as the other requirements of being an electromagnetic weapon. Coilguns do probably deserve their own research but with current technology(maybe something like room temp superconductors will make them more viable) they just can't keep up with their rail based cousins.

Hi! I’m definitely not a Chinese scientist trying to build this so my family doesn’t die. But don’t the electro magnetic fields the gun generates interfere with ship systems around it?

Thanks for the information

@@kurtru5selcrowe607 Yes, that's a real issue that we were looking at but our goal was to get the thing working. It's another reason why railguns may not be practical in combat. One theory from the USS Forrestal fire was that a jet going through a radar beam may have triggered the missile that caused the mishap. The military has some pretty stringent requirements about stray EM radiation. en.wikipedia.org/wiki/1967_USS_Forrestal_fire

The big problem is barrel wear. That's the main reason they've cancelled them all, needs new materials science

@@MostlyPennyCat I'm pretty sure some agency is researching composite alloys for railgun barrels.

@@MostlyPennyCat Modular barrels of some kind. Ceramic-polymer backing layer, also modular, and swap them over time. It's having that level of production which probably gets in the way.

@@joeclaridy im that agency

@@MostlyPennyCat I don't think there is any materials science which can save the concept.

Wouldn’t blowing up an ICBM cause the explosion and then knock out any generator powering the rail guns?

@@geneawisea2708 If you're talking about intercepting a Nuclear missile and that resulting in an an EMP it wont. Hitting a nuke won't set off the explosion, the nuke's internal payload needs to detonate to start that reaction.

@@geneawisea2708 No. A nuclear device uses precisely timed high explosive implosion to attain super criticality. If you blew the MIRV apart with a kinetic impactor, you would get contaminates raining down in the form of particulate fissile material, but no detonation. The detonation has to be >>> perfect

@@cheddar2648 pretty much all of the modern ICBMs carry multiple warheads. Depending on configuration even if you managed to destroy one warhead you can trigger either separation of the warheads or a boom. On the other hand for the dirty bomb, that you describe, you actually need an explosion. The only way to shoot down ICBM safely is long before it enters atmosphere. The energy of the projectile should be pretty high and it should have smart weapon capabilities. You cannot replace $50 million sm-3 block 2a miscile with $10 projectile.

ICBMs travel at much higher speeds at least "Mach 23" to get into Space for a ballistic Trajectory An intercept missile has to be "guided " to the target. ABMs travel at Mach10 + ( see Sprint ABM missile as example ) so this weapon is A backwards step in speed

Well, when I worked on them back in the '80s, you could easily fit one in a shipping container.

It seems like barrel wear could be eliminated, heat is the big issue, but maybe some kind lol liquid nitrogen coolant or maybe some form of super conductivity using super low temperatures to maximize the electrical efficiency as that could help cool the system. One idea I had was cooling the entire barrel with a jacket of liquid nitrogen kinda like a browning machine gun from WWI, it’s not the first time we have had challenges from hot barrels, even the MG42 had spare barrels

They haven’t. There are theories on how to address it, but there’s hasn’t been the “We have solved it” test

Barrel and ruining a magnet both need to be fixed 🤔 so why not change the barrel after 5 shots like the g10 4 barrel assault gun

Exactly - if they haven't progressed in keeping the weapon from tearing itself apart, the video is just another fluff piece.

the US Navy demonstrated the rail warp / melt problem had no solution. In addition, the power storage requirement consumed large volumes of shipboard spaces. Many container-sized electrical storage units per gun. In short, impractical with current technology. Maybe future.

ye amd these will probably need a lot of electricity for each round

The project just gets highs and lows of funding, i think the engineers use new research, quickly build a prototype and get a test in, then they wait again for further advancements in other areas. Bit like how fusion is just ticking along…this tech will never stop being watched, as missiles are good but a system that can work without navigation is a good back up just in case…but we have lasers now,

Surprisingly little actually

I imagine your partner often says more length in your arena would be welcome too.

and that's why most of the world is moving towards missiles. why make an obscenely expensive cannon when you can just mass produce guided missiles ?

@@Lapantouflemagic0 I imagine this could have certain advantages over missiles, the projectiles may be alot cheaper, and it would deal immense damage.

​@@vegasspaceprogram6623 the projectiles, yes, would probably be cheaper and could be carried in greater number on the vessel. i think that's the main advantages of cannons (railguns or not) over missiles. but still, as cool as railguns are, i'm not sure they are actually that interesting. lasers are probably much better and can be used defensively.

We aren't. We are ahead in most respects.

We arent lmao

People love to complain. Americans have believed that we've been in decline since 1855. Our opponents are autocrats who love to overestimate their capabilities while in the (mostly) free speech West we see more viewpoints both true and fictional, with the bias often favoring tearing something down.

Can those lasers shoot through clouds/fog?

The problem is magnets lose power when exposed to heat. Meaning frequent rail replacements. Also the acceleration means it's unlikely for any electronics to survive being fired to guide the projectile how they want to

@@hf117j it does use magnets. it use electrical current to generate a magnetic field. The barrel consists of a pair of electrodes long the entire length of the barrel and electrical current is dumped (shorted) across the projectile which creates an opposite magnetic field generated in the barrel electrodes.

Why? The weapon seems pointless when hypersonic scramjet and glide vehicles will be more than capable of neautralizing enemy ships at a much farther range.

Not gonna happen. Completely apart from the problem of energy density to power it, hypersonic rail guns more or less destroy themselves in just a few uses at most. But there likely will be ramjet projectiles fired from conventional guns which achieve similar speeds with infinitely less problems.

So you want to limit the weapon systems we field based on possible redundancy? That mentality is why the Air Force built F4 Phantoms with no cannon initially. Once we overcome technical problems the system has wide range of uses beyond simply trying to compete against a missile or rocket.

Ya, often with high powered railguns, the rear part of the projectile is vaporized into a plasma. It increases conductivity between the two rails, and the expanding plasma assists in pushing the projectile a bit. I bet that is what is seen exiting the barrel here.

why? why needed?

@Fred Garvin the heat warps the barrel.

@Fred Garvin The "barrel" is not worn down by friction, but by the rails being blasted apart by the intense electrical arc between the rails. The gun damages itself with every shot.

@Fred Garvin "windings" ? Are you thinking of a coil gun? This is a rail gun. 2 rails, an aperture, Lorentz force, and scary amounts of electricity running through it all.

@Fred Garvin The wear he is talking about is the contact rails in the barrel. The energy used to fire the projectile literally melts the contacts each time it is fired.

That was the Railgun being developed by BAE Systems. This is different, currently separate from the Navy IIRC

Its for show. I doubt it actually works. They can barely build AESA radars without thieving from the US. They stole KB's of data on the EM launchers for air craft carriers and the F-35s radar and other data.

Sheesh, sounds super useful, can’t wait until they try to use it during war and it gets bombed before it even has the chance to get setup. Wonderful

Ok. Look at the size of the one they testing and how many cables are attached to it. If the US Navy did the same thing with current technology the size and power required would be comparable.

I don't even buy that it's anything but an empty turret. China has built entire fake cities. I wouldn't put this above them.

Dumb idea from a dumb guy, but what if the barrel could be filled with saltwater? There could be tubes that “charged” the barrel between shots

im sure with their kind of funding they have made a material to account for those problems. the military wouldnt decide to refund it if they thought a weapon like that would only hold up for a short time frame. remember they want their ammo cheap, not the material used to shoot it.

Agree- barrel technology needs to be revolutionized to make viable.

Don't need a boom if all the squishy parts become so much interior paint.

That's because magnets lose their magnetism when exposed to enough heat. And all the power running through them to fire it heats them up with every shot. It essentially needs a coolant bath in the process of firing to minimize how much magnetism is lost each shot. Edit: I know someone that worked on it and my only suggestion was to try using the seawater. It is meant to be on a ship. But I meant more of a coolant loop with seawater. Not direct exposure

Actually, current at sliding contacts is so large that plasma forms at the interface and the resistivity stops current from rising more. It is a power-limited device.

What I'm thinking is more along the lines of a viscous synthetic oil that has conductive particulates suspended in it, able to close the circuit and absorb a significant portion of the waste heat upon firing. Also, as far as I know, there isn't any delicate circuitry inside the barrel. It's literally just massive strips of metal for conducting a massive amount of power.

I think using a coolant would be a good idea. Maybe you could make the rail hollow and pump a coolant through it. Perhaps they already do. There are other non-obvious ways of cooling. But perhaps the real problems nowadays are in material science. We need new materials to make things happen.

Thats not a railgun, it's a coil gun. Rail gun ammo contact 2 rails on either side

IIRC, railguns are a lot more efficient as far as converting watts to acceleration, as you need a certain amount of space between the coils and the projectile. In coilguns, you also need extremely precise timing on the coil initiation, or you waste more energy on top of that.

@@aceg81There are something like 30,000 linear accelerators in the world -- they are basically coil guns. Rail guns have a limit to how fast they can accelerate an object (16,000 m/s), plus they generate recoil, the rails want to push apart, and they need to be replaced. Coil guns can theoretically accelerate things nearly to the speed of light, with enough coils, power, etc. A rail gun uses the Lorenz force whereas a coil gun uses magnetic fields. There are pros and cons to both.

You're on the right track. This work was done piggy back on the requirements of CERN and LLL and SANDIA. The capacitor tech and sizing are very similar.

It probably would be. It generates it's own electromagnetic forces, and in vastly greater extremes. It basically makes localized EMP's when firing. But it's a wildly impractical program, which I seriously doubt could field a field unit even if they had 50 years of time & funding to develop it.

Also, if you impart too much energy into the projectile in that very short distance, enough to make 'kinetic kill' artillery warheads, then the interior of your gun is subject to the equal and opposite forces needed to generate that velocity. Rail guns destroy themselves. To such an extent that there isn't even any super-expensive exotic materials tech which can save them. Above and beyond energy density, rail guns have a fundamental physics problem. (although "less than hypersonic" rail guns may one day actually be practical ...maybe)

🤣😂🤣🤣🤣 Way to point the obvious out. I think that's why these type of weapons are still in the R&D stage.

@@antr7493 And they'll stay in the R&D stage for as long as there's money to burn. I work in the def industry, I know media likes to unjustly cry wolf on military hardware programs. I mean, I think think the F-35 is a fantastic aircraft. But railguns are the real deal, when it comes to being just a money-grift.

Chemical propellants have a limit on acceleration potential and we are very near that threshold at all sizes of weapons. To accelerate a projectile faster, you need something that can impart way more energy than any chemical reaction we know of that is that compact. Some possibilities exist, like the Electro-thermal chemical cannon, which in theory creates a stable, predictable rapid burning propellant that would nearly double projectile speed on Tank Gun (and any artillery cannon for that matter), but this still pales in comparison to a Railgun. Simply put, despite the power requirements and complexities, Railguns can accelerate projectiles to speeds that no chemical gun can hope to reach and allow for ranges that put even some missiles to shame, while being more economical on a per projectile basis and have deeper magazines. But the main issue isn't even the power consumption or discharge, that is solved for the most part and further advances will result in significant miniaturization. The main issue really is barrel deformation. In order for a Railgun to work, the projectile casing must be in contact with the barrel at all times, to complete the circuit and accelerate the projectile. But the energy needed for this is so high, that the barrel basically begins to melt after a few uses and becomes unusable after a few shots. To date this has not been fixed and is the reason why Railguns where never fielded for trials, much less operation, as the barrel wear and tear makes them unusable. Until this major hurdle is overcome, Railguns will be a weapon of science-fiction, but once this is mitigated to a more reasonable level, then they will outperform any modern gun by a long shot.

@@antr7493 I don't think any directed research is necessary at this time. We know the problems but haven't the science to solve them. We can continue doing research into new energy sources, conductors, and structural materials independently of rail guns, since these ideas would be more useful elsewhere. Until we tick off the list or come up with new concepts, this idea should be shelved. I give the US military credit for trying and then giving up. Not all problems can be solved by money and time.

point it upwards and it follows a ballistic path like artillery

@@anthonydewitt7674 but then it would lose the penetrating power surely, it would be just like any traditional artillery except obviously go a lot further.

Line of sight only. The speed is the ethalpy, without the speed it has no teeth. MVSQUARED, M is insignificant and better if low as possible

@@anthonydewitt7674 The speed is required for the impact to cause enough damage. And the speed is lost quickly because of air resistance, which greatly increases with speed. So a ballistic trajectory (>45°) seems to me like it wouldn't work very well. imho, it's more like a tank gun with a range of less than 10km. (maybe only around 5km)

@@Robbedem at 110 miles- the existing titanium projectile is still traveling mach 3. a 25lb. projectile going mach 3? like getting hit with an m1 Abrams main barrel projectile- LETHAL. especially when you don't even see it coming. the interesting question I have? they believe they can DOUBLE the range to over 200 miles? so.. maybe a mach 7 muzzle velocity? exciting times- big development. perhaps they plan on using a tungsten projectile of smaller diameter / better drag / loss? something shaped more like a match grade boat tail rifle round with smaller fins perhaps.

i thought about these too

Can't triangulate the source of that electromagnetic noise, if it's so intense to fry the detectors (it is, cause what do you think is gonna happen with thousands of volts and millions of amps going thru a big pair of conductors is gonna do?). The bigger (and still unsolved) problem is barrel wear. You get currently 3 shots before the barrel is worn out.

@@44R0Ndin lol that’s a whole world worth of energy consumption you’re talking about. You would have to carry a few nuclear power plants with you to power it…

@@avashurov Nah it's not a lot of energy overall, (maybe a megajoule or so) cause the firing transient doesn't last very long (like a fraction of a second). So while the power is immense, the time is tiny. That's why the rails erode so fast, the power is too much for the rails to handle.

Plus it will look way cooler.

Just no. Light traveling at the speed of light will never discharge a fraction of the energy of a solid mass traveling at near the speed of light, which is the potential of an electronic propulsion system. It's a solid metal Laser blast.

@@Chrisfrom_Dallas Laser light can destroy at the speed of light. Imagine the power of a lightning bolt ⚡️

@@mikewalsh1402 lightning is a jolt of electrical energy, not light

@@xela79 True

Go simple- Brass sabot.

@@jozefkozon4520 why brass?

@@joeclaridy Soft+conductive+cheap

No because that's not how Rail guns work. The pair of electrodes needs to short across the projectile to accelerate it. The current needs to flow through the projectile.

@@jozefkozon4520 Not practical. brass will vaporize before it leave the barrel create a toxic cloud of zinc (brass is made of copper & zinc).Brass has way too much resistance to work (about 5 times more resistance than copper)

Probably depleted uranium or tungsten?

@@cosmicyeti6804 I was also thinking tungsten. DU would be an ecological nightmare from when the shell splinters and get embedded into the surrounding environment.

@@cosmicyeti6804 more or less what I figured, thanks

I think it's actually aluminum, but maybe that's just the sabot that encases it until it leaves the barrel. You don't need those extremely heavy metals for these, energy is 1/2mv^2, so the energy transferred to the target is unbelievable at those speeds, basically an explosion w/o any explosive material in them. Look at the penetration tests as well, these go through many plates of steel like butter.

@@cosmicyeti6804 I don't think DU can survive being fired. My guess is extremely strong steel (structurally strong, rather than hardened), or aluminum which suffers less strain in 30,000 g's because it's lighter. Not that it matters, the guns can't survive being fired either.

Highly unlikely.

Not at 500 million.

No, that still belongs to the F-18 and all of the multiple fixes they had to do to them. Tens of billions of dollars, 500 million is relatively cheap for a decades-long project. The ammo costs way less for rail guns and lasers too. Edited because I got the F-number wrong.

well the barrell wear compared to a glide vehicle is still very cheap. also the will be our best way beside lasers as stationary icbm defense.

I heard its the forces that seperate the magnets on the far side tend to warp

Although these vehicles are hypersonic their maneuverability is still questionable. Even if they're maneuverable hypersonic vehicles the space it takes to execute a turn for a non-hypersonic vehicle is a few hundred feet to less than a mile whereas a hypersonic vehicle executing the same turn would have traveled several miles. This is why in the hypersonic age the US still continues to produce subsonic missiles.

@@Thor_Asgard_ cheap but it limits rounds per minute. The navy wanted something that could fire 6 rounds per minute but that rate of fire would destroy the barrel faster.

rail guns pretty much destroy themselves. if you look at the kinetic energy imparted onto the targets... an equal and opposite amount of energy is imparted into the gun. The barrel liners disintigrate very quickly, the structural components of the rail gun warp, the magnets break and/or melt... they can't even get a one-off "laboratory princess" rail gun with expensive exotic materials to survive being used multiple times without being rebuilt over and over.

This weapon is quite frankly extremely useless, Somuch so that this entire weapons program was scrapped and removed, US army is not researching this anymore, It has far tomany issues, range being bad, cant fire more than 13 shots before the rails need to be replaced, huge power demand, each time a shot is fired near electronic radar equipment there is major scrambling issues.. Not sure why this video released after the project died when this project has been dead for months lol

It figures. What else is new. Flag officers would have to to exist on their pensions.Boo-hoo!

They canceled it due to excessive wear and tear on the barrels. Material science isn't sufficient at this point.

@@williamwallace9685 You got it right!👍 The barrels have a very limited life span. Plus, the ammo used is limited to just a few types. So it could never replace artillery.

@@williamwallace9685 that's how I understood it too. So I doubt the rapid fire ability, practically speaking.

@@williamwallace9685 not saying corruption wasn't a part of it , but consider the following: 1- Lying about the project being cancelled can reduce enemies' awareness and interest in the tech, giving the US the lead in the tech. 2 - Missiles can be fired from the air , submarines and mobile ground units, while stationary/heavy railguns might be destroyed by the enemy in a preemptive strike.

The problem with the Rail Guns , they need to much energy for one blow and energy is precious for a combat ship middle of the ocean
