  • It moves so fast it ignites the air.

  • Stupid friggin' video! It's a compilation of 2 totally different videos, which have NOTHING to do with eachother.. The first shown gun is NOT a railgun, and the second video shows the US Navy railgun shot - obviously not the shot from the hillbillies "cannon".

  • show me the actual weapon later. and it MUST be placed on a Rex style walking tank.

  • @CaptainJetJakal Ohh yeahhhhh METAL GEAR!!!!!!!!!!!!!! lol

  • Wtf, this is not a railgun. You just cut footage from a railgun projectile at the very end.

  • i thought that rail guns look a little like bazookas, except it had two steel rods that would fire electric pulses that would shock the $#!# outta ppl... if they havent started working on that.... yeah.... i could probably invent a rail gun....

  • when he sid that cap over the projectile it squiled like a door, must be a tight fit, mmmmmm

  • No, it edited the video in slow-mo, its a solid fuel rocket! 1:00

  • @you54312 No, that's the friction the projectile has with the air.

  • long barrel is loooooooooooooooooooong

  • That isn't a friggen railgun. You got a bid of some guys homebuilt cannon or something and made a fancy looking projectile then used footage from a real railgun to show the REAL bullet. FAKE

  • its calld a sabot round. pronounced saybow. kinetic energy round.

  • thats not a rail gun, it's a cannon.

  • @Dubsackjack to clarify, it was the ammo of the rail gun that they were testing here. the info for the video is a little misleading. funnily enough, though, the title isn't misleading in any way.

  • So this isn't a rail gun FYI. I'm seeing footage from two separate videos here. First one being some old cannon and the slow motion clip is from an actual rail gun test firing.

  • Kinetic energy = (m*V^2)/2

  • Mass * velocity is force... Not momentum.

  • No, Force is mass * acceleration.  Momentum is mass * velocity

  • pfft. dumbass. Go make idiot comments in another video. like of your mom masterbating.

  • The equation for momentum:

    p=mv

    Momentum = mass x velocity

    So something that weighs 1kg can be just as devastating as something that weighs 500kg.

    Equation for kinetic energy:

    KE=.5mv^2

    Kinetic energy = 1/2 mass x velocity squared

    Very similar to momentum. Again noting the mass/velocity relation.

  • Hey any old artillery guy will tell you that the undercarriage is from an 8 inch (203mm) howitzer....yup...know that system only too well. We fired some mean stuff ourselves!

  • amazing

  • Extremely high speed kinetic rounds actually transition from the solid to the liquid and then to gaseous in a short period of time. This releases a tremendous amount of energy!

  • yeah, even on videos of homemade railguns, there is a (smaller) flash as the projectile is fired.

  • wots a rail gun

  • its a rail that generates massive amounts of energy in electromagnetic form and it uses it to force a solid metal projectile at more than 8 machs to the speed that when the projectile hits an object the kinectic energy stored in the projectile from moving over 8 macks will cause a large shockwave and simulate a explosive round...but the rounds r cheaper

  • a big ass gun.

  • why so fast?

  • That's not an electromagnetic railgun. The one they're loading is an early WWII (i think) 'railgun' cannon, so titled because it was pulled around on railroad tracks.

    Like slashest said, there is no explosion with an electromagnetic railgun because it uses ELECTROMAGNETS rather than gunpowder

  • incorrect there is an explosion. the sound waves collapsing and the intense heat ignite the oxygen on real railguns.

  • Sorry if this is a stupid question, but what exactly do rail guns fire? Just a metal stud?

  • Yeah, they can even fire friggn granite :P

  • yep, thats almost the whole point of railguns, they dont have to fit explosive projectiles, they simply fire a solid metal projectile, and at the insane speeds they are going, they can be more damaging than explosive rounds, think miles per second instead of meters per second =)

  • if you fire from a railgun the same projectile they use on 12inch guns in battleships..are you saying the effect is more damaging than the explosive projectile?

  • it is a LOT more damaging

  • just think. a meteor which travels at 30,000mph the size of a pea can make a pretty big crator in the ground. imagine something 90mm's traveling at 15,000mph. ive read that they managed to get 15,000mph with only using 30% of its potential power.

  • they should strap someone to it and make them fly. but they should have a cushion for when they land ;)

  • @Sensoubandit

    Thats slightly over-estimating the power of a meteorite the size of a pea. There have been instances recorded of people ( Even an kid ) getting hit by one in his palm and survivng.

    But still, I Agree with your general point.

  • The rail gun projectiles are usually much lighter than their explosive counterparts (a battleship shell can weigh around 300 kg, whereas a rail gun shell is usually around 3 kg). In spite of this though, the sheer speed of the projectile causes it to be as devastating as an explosive 300 kg projectile.

    In other words, you can carry more shells with no risk of explosions on board, with just as good weapon power. The rail gun is a fantastic invention!

  • @Athaeus Sadly, the conductors necessary for a high enough voltage and ampere are much heavier than the conventional gun would be. Pure electromagnetic guns atm are more of a feat of engineering than a practical wapon. Current military research on EM-phenomena is rather focused on using plasmatechnology to optimize the blast of conventional guns, and its rather an incremental advantage than a big breakthrough.

  • @Athaeus actually it's been stated that the Rail Gun round is as powerful and devastating as one of their Tomahawk missiles (Source: Office of Naval Research)

  • @daedalus357 But a cruise missile can be steered to its target while a rail gun projectile, like any bullet, just follows a ballistic trajectory.

  • rail guns = awesome.. in real life and in games :P

  • Holy shit.. Imagine putting nuclear warheads in that thing...

  • Nah, they'd get damaged too much to use in long ranges. The money you'd have to spend on encasing the warhead so that it doesn't render itself useless during flight... I think it wouldn't make such a difference anyway. A nuke explodes because of its payload. I don't see why a higher kinetic energy should make a great difference.

  • that barrel is stupid the only use you could get out of that is to try to line up with a enemy craft carrier and hope you can sink them what a waste of tax payers money.

  • The rail is very usefull. It will shoot things faster. That was just a test gun. Not the real thing.

  • ummm.....have you ever heard of long-range artillery? All you have to do is get an angle and adjust for windage, the rest is entry-level calculus. That's a depleted uranium sabot, the kind used by tanks to punch through up to 2 feet of reactive plate steel armor. Imagine what it'll do to a concrete bunker when it lands at 3800 fps. Buildings can't run away.

  • You people are idiots. The first part of the video is a projectile test utilizing a depleted uranium sabot round fired through an artillery test man barrel to attemp to achieve results comparable to a rail gun. If any of you techno videogame geeks spent anytime in the service of your country instead of in your mothers basement living out your fantasies on xbox/ps3 you would know this.

  • actually i DO spend my time in the service of our country, and i didnt know that...

  • if anyone knew even the slighest bit about rail guns, they would know that there is no explosion associated with fireing it

  • besides the massive amount of friction created as the projectile travels down the barrel...

  • or the capitors firing, or the sound barrier.

  • i didnt know that lol all i know is it look cool and deadly

  • the outside of the projectile gets vaporized and turned into plasma that is what your seeing

  • not a railgun only a normal gun...the last second's are from a railgun

  • Fake video.

  • a depleted uranium slug is what alot of modern tanks use cos its a heavier metal than steel. nothin to do with the radiation or the metal it just causes a shitload more damage.

  • that look'es not like a railgun....that look'es like more an atillery cannon but not a railgun...for sure the first sequence are not a railgun...at about 0:56 till end thats a railgun but not the first sequences...for sure

  • yea looks like guys loading a cannon and puting rail gun footage at the end. You can see carbon fouling in the chamber at the begining.

  • ya know a rail gun is sapose to fire a spent uranium slug right i see no radiation protection

  • You've watched too much movies and played too many games. A rail gun is supposed to fire a piece of metal at high speeds, what that piece of metal is made of doesn't have to be spent uranium.

  • whoever said a rail gun has to fire a spent uranium slug? how would that help the effectiveness?

  • Depleted uranium is incredibly dense, and has unique cleaving properties. When shot out of a rifled barrel, it's spinning motion keeps the projectile from deforming, instead, it "sharpens" the projectile to keep a sharp point traveling through the armored target.'

    Armor-piercing + extra kinetic energy = incredible heavy round.

  • = incredibly scary round

  • so railguns are uranium projectiles fired with magnets from a rifle cannon at a mach 8 speed???

  • If only there was a compact version of that bad ass weapon.

  • Remember the first gun created, big, with one ammo and a minute to reload.

    Now, you can find Beretta (for example)

  • what's the power generator for this gun? The current got to be huge.

  • Solid Snake : METAL GEAR?!?!?!?!?!?!

  • BROTHER!

  • i need one of those!

  • Real railguns use electromagnetic rails to launch much larger versions of that tungsten projectile

  • dude, tungsten is not magnetic...

  • It dosnt have to be, it just needs to be conductive, which tungsten is. Exactly how it works im not sure but i know that much.

  • more like a rail tank bazooka

  • i understand the principle, but the real question is, would it be prectical to put on a ship due to the power needed in order to fire the big schtick. My guess is that they would need to fefit an aircraft carrier sinse they alreadt have nuclear reactors.

    also, a simple hollow cone or even a sphere would be better in my opinion because, if i understand correctly, the heat and speed generated would cause the projectile to be turned into molten metal anyway due to air friction.

  • Actually, they use a homopolar generator and a simple 1 megawatt turbine to spin the homopolar generator up to speed. Once at speed, which only takes a minute or two, the short the launch foil to the rails. The entire million amp current of the homopolar generator goes into the foil generating a plasma cloud and the rails keep that cloud *charged* and *HOT*. It's that expanding cloud of plasma that pushes that projectile along.

  • The first thing i noticed was the blue plasma.

    So it's not all that different from regular firearms, instead of expanding gas from powder, we have expanding plasma from a generator.

  • plasma is still theoretical, I don't think mankind has ever created plasma before. Maybe superheated particles, but not plasma.

  • Plasma is created all the time! Do you have fluorescent lights in your home? Plasma. The sun? Plasma. A lightning globe? Plasma. An electrical arc? Plasma. A flame? Plasma.

  • It isn't the plasma that pushes the projectile; it is the Lorenz force. The plasma is just a conductor, used because it is the only conductor that can stand up to a million amps of current.

  • plasma is unbelievably common. we don't create it, however we can use it.

    if you know about the "law of conservation of energy/mass" which applies to everything.

    ("X" relates to anything at all you want to stick in the sentence)

    X cannot be created or destroyed, only changed.

    basically, we're turning substances into plasma...

  • i understand the principle, but the real question is, would it be prectical to put on a ship due to the power needed in order to fire the big schtick. My guess is that they would need to fefit an aircraft carrier sinse they alreadt have nuclear reactors.

    also, a simple hollow cone or even a sphere would be better in my opinion because, if i understand correctly, the heat and speed generated would cause the projectile to be turned into molten metal anyway due to air friction.

  • Total Penetration! xD

  • It's not a rail gun people! It's a test of a projectile that could be used in one.

  • @neep28 it is a railgun, the smoke and fire you see is caused by the high amps reeking havoc on the area around the projectile and the projectile itself, like a plasma cutter does to metal.

  • @MnstrSubrbn that is not a rail gun but a kenetic projectile used for one....maybe if you spent the same 15 secons by even just googling rail gun, you could find the information before making a comment like that

  • that thing must use a lot of energy so how are they gonna put it on a ship?

  • uhh... that doesnt look like any railgun ive seen. the only thing that is part of a railgun is the slug.

  • i just went through some of the comments and i think i need to clear something up. others have said this but i dont think they did it in the clearist way, so that everyone can understand it. the video is showing the projectile being tested in a cannon. not a railgun. but. the projectile is made for a railgun. they are merely testing how well the projectile functions before putting it in the actual railgun. as for the footage at the end. it is probably the finished product in the actual railgun.

  • Read the Top PROJCTILE TEST. Said nothing about it being a Railgun.

  • It's just that Quake got a fake railgun.

  • Fake! that's not a rail gun!

  • you have no idea what you are talking about

  • Thats no rail gun.

  • what's not right?

  • Yes g2y2q2. The projectile at the beginning is being loaded into a breech loading cannon, a long one. The shot of it being fired is from a completely different video. I don't think the us navy test fire rail guns in a forest!

  • Are you for real. It's not a rail gun. Look at the title of the video, it's the projectile that's being tested not a rail gun.

  • Are you for real. It's not a rail gun. Look at the title of the video, they are testing the projectile, not a rail gun.

  • they faked it from the navy's footage. the projectile they put in was pointed. The one shown on the footage was blunt. The target they used had a crosshair type thing on it, while the footage target had an emblem on it. That thing's just a really long cannon.

  • MOTHERFUCKIN AWESOME!!!!!!!!!!!!

  • Is that for real? That is the BIGGEST freakin rail gun I've seen in my entire life! WOAW.

  • why would there be fire? a rail gun uses electricity and coils of copper wire to accelerate a meatal projectile.

  • NO. This is a railgun, that means, it uses no coils. Instead of this, it uses two rails, that are under high voltage. Between that two rails, there is the projectile. When it's fired, floats a very high electrical stream through the projectile - maybe more than one million ampares!

    That unimaginal big power is responsible for the fire.

  • They have a rail gun in Heli Attack 3.

  • yeah but imagin carring this gun around

  • WOW this video is completely false. That gun did not fire that projectile that it showed at the end of the film. That first gun was not a railgun but a standard cannon. The last part of the video was a completely different weapon which was a railgun put there to make it look like it came from that cannon.

  • correct, that railgun is the navy's u can see on other videos here on youtube

  • yea, ur rite, that was not a railgun, that was a cannon, and they put the bullet in a insulator (plastic), railgun bullets need to be conductive so the current can pass through it...

  • so true

    if its fired by magnets then why was their a giant fireball comeing out of the wall

  • there are massive amount of current passing through the projectile and down the length of the gun therefor the small sabots ont the projectile willl ignite causing the fire

  • That's not right at all...

  • It's explosively injected into the barrel

  • At 5 miles per second, the air friction creates hot gas (plasma) there is no ignition of any sort.

  • plasma? wtf... master chief wasn't born yet dude

  • lol, there is such thing as plasma and its easily created

  • This argument about "it is a railgun" "no it is not" is just plain dumb. Go read the original test at the Naval Warfare site: this is a test of the PROJECTILE for the naval railgun using a STANDARD BREACHLOADING ARTILERY PIECE to fire the projectile.

    The gun featured in the video is NOT a railgun.

    Now I KNOW some moron is going to come along and say "yeah it is" but you can verify the information I at the Naval Warfare site (and get your own copy of the original vid)

  • im sorry but that was most deffinitly not a rail gun. that was just a testing of a new projectile in a standard cannon. a magnetic rail gun would have a large array of electromagnetic coils spaced evenly along a rail hence the name railgun , not a 1940's model naval cannon

  • rail guns don't fire projectiles they fire a straight beam of plasma, but coil guns fire projectiles.

  • uhm they fire solid rounds. Not plasma.

  • Lol, Plasma isn't yet able to be harnessed... Not large amounts like you would see in Halo or movies. Sure you can get minor jolts and such, but we're not going to be seeing "plasma rifles" anytime soon. Railguns are not plasma-guns, but projectile guns. They use magnets to propel a projectile.

  • Actually plasma is able to be harnessed, Boeing is testing plasma-based weaponry and it is a pretty basic concept:

    Hydrogen is put in a magnetic bottle, Superheated to plasma, one end of the bottles magnetic field is lowered and the plasma goes out through the weakend field. However the plasma will only go a few inches because of the atmospheric pressure

  • Even in space it would cool down rapidly.

    Its like a burning hairspray ball....I would try to compress it...

    But you are not talking about the airborne laser carried of a boing right?

  • you have been playing too many video games... even Wiki has the facts straight

  • heh, acualy for arfexnex, hes sort of right if a plasma cannon were to come out it would be called a rail gun and to the other acualy we have harnessed plasma, its not that hard acualy jsut ionize a gas and boom plasma, any way we have plasma torches nfor cutting jsut no way to make it go more then a foot

  • That was a cannon barrel with a breach. You can't just retrofit a cannon into a rail gun. Someone has done some editing here.

  • this is real

  • it's a edit job of a nuw projectile, for use in a rail cannon, and the jan 31st railgun test.

  • Yes, it's technically a railgun. There's no warhead, it's a solid metal projectile with a sabot that gets destroyed upon firing. The sabot serves the purpose of allowing an aerodynamic projectile to properly complete the circuit along the rails, without causing the projectile to be arc-welded in place. It makes sense that it would vaporize/combust as seen in this video versus other concepts where it was discarded like the shuttle's booster rockets. Railguns usually aren't like the movies.

  • That doesn't make it a rail gun. The video title is railgun projectile test, It's not a test of a railgun but of the projectile.

  • and this did work, obviously!

  • it is a railgun

    watch the video!

  • is that the gun from the game doom

  • moron rail gun is magnetic that means no friggin flames

  • If you got no clue whats going on stfu -_- so many smartasses on utube...

    The projectile gets heated up by the magnetic field and probably friction as well.

    -> plasma/flames

  • That's not a fucking railgun.

  • yes it is

  • It's not a railgun.

  • 約1分からレールガンの映像。

  • 火薬使ってるじゃんw

  • 言ってるの推進については、メソッドのですか?

  • fake..

  • Fake..

  • Freakin wicked. Solid metal object being fired up to 5,000 mph, by harnasing electricity. I want one.

  • thats NOT a railgun, lol..

  • Yes it is a railgun, the flame you see is a combination of the sabbot being eradicated and the mach 5 shockwave coming off the back of the projectile. Remember when talking those kinds of speeds there's a reason explosives are not required, raw kinetic impact. I'd love to see the crater that thing leaves.

  • =\ Assuming that's where the fire comes from (I don't see the carbon, I don't see how it has any fuel to burn unless you're saying that metal catches fire or something...), why do I not see huge coils wrapped around the barrel?

  • because it's not a coil gun.

  • remarkable peircing power now if we can only pierce the strongest carbon in the world which is 100x stronger than steel

  • What did they wanna do?

  • Yea. You know what that means right? With a Rail Gun that powerful and able to shoot that far, now the United States can use electro-magnetic energy to launch Nukes. That way, they wont be in violation of any peace treaties.

  • Supply me with a link which includes the treaties which explicitly states that the method of launch has anything to do with the legality of deployment of nuclear devices. Thank you.

  • yeah wtf is that guy talkin about.

  • look for information on the hot shot nuclear artillery cannon, developed during the 1950's.

    i'd imagine that the amount of current dissipated through the sabot of a railgun and the extreme electromagnetic flux during firing would make loading any kind of sophisticated payload, such as a nuclear weapon, very difficult.

  • you are an ass.

  • The force would crush the warhead in the gun, thus annihilating anyone who was stupid enough to try such a thing.

  • KICK ASS!!!

  • pimp

  • Metal Gear?! lol

  • Ill pass on getting shot by that thing!

  • notice how they decided to blow a hole into the actual naval research emblem. that says they would like a little more money to keep working for em.lol

  • yea, AWESOME

  • all right u show that evil peice of paper whos boss

  • Hurray for warfare! Population control yeah!

  • fucking sweet

  • Kick ass. Where can i get one of those.

  • OH SH1T!!111!!1ONE!!1ONE

  • wow..., looks destructive

  • Fuck that is one big ass SAVO round!!!!

  • It's actually a "sabot" round. I think I read that this one hits the target at around Mach 5. That's a lot faster than the ones coming out of a tank.  Scary to be on the receiving side of that one...

  • AWESOME!
