  • oh navy railgun, you so crazy

  • Kids in Africa are dying from malnutrition and they prefer to spend billions of dollars on railguns

  • Is it accurate?? It doesn't spin and there really isn't much of a barrel to guide it so... yeah I'm doing a science project on these things so I want to learn more about them.

  • How fast was the projectile going? I read Mach 7.5 but I don't know if that's the goal along with the future 64 mega joule shot or if it was the actual speed of this one...

  • Comment removed

  • Railgun tech will eventually be used to shoot cargo payloads into orbit, or even to other planets (once we get those bases on Moon and/or Mars going), since it's the most efficient way of doing so once you build a nuclear plant nearby. So, yes, this is a boon for humanity.

  • EHH, Quake 3: Team Arena did this with the hand held rail gun, Old News lol.

  • What in the world is the US going to do in 2030 when this comes into use and no other countries are really interested in a war?

  • @cdoftx I'd be surprised if we'd ever reach such a world and time where no other country wants war, directly, proxy, economically or other. That said I'd rather the US have it than any other country. For all the political BS between our two parties it hardly compares to what's happening right now elsewhere; beyond mere politics that is.

  • @Schwaltzvald We're almost there. As much as the world hates one another, the global economy has brought peace. Take China. In the 50s we were fought them in the Korean war and were talking of nuking them. Now we trade with them so much we tolerate each other, even if our governments are opposite of one another. The threats we see today may seem big from TV but compared to the Soviets they're minute.

  • i wanna know how much people gonna be killed with this gun,in 'accidents' that mean tests

  • Too bad you need the power of like, a city to fire it.

  • @Apocol0id The reactors on the Nimitz could charge up over 6,000 of these railguns at once, and the gas turbines on an Arleigh Burke could handle over 2,000, so power isn't an issue. The real problem is the weight and volume of the capacitor banks, which occupy the area of a small warehouse and weigh some tens of metric tons. Also, the barrels on current prototypes only last a few shots.

  • @MuratMagomedov Idiot. Look up 'racism' in a dictionary before you next make a fool of yourself.

  • @su79nioj you obviously have no life if you spend your time looking through 50+ comment pages to find a comment from 2+ years ago.

  • @MuratMagomedov Wrong again. You may have looked though 50+ pages of comments - I just clicked on the link that took me to your comment.

  • @su79nioj so you have nothing better to do than to respond to comments from 2years ago? (surprise, surprise)

  • @MuratMagomedov I felt it important to correct your mistake. You ought to learn what 'racism' and a 'racist' actually are before you use them to label other people.

  • perfect bc3 weapon

    

  • velocitas eradico = "I get rid of the speed."

    ...

    well, sure, all right

  • @0RPH3U5the666r3ml1n

    The translation is more along the lines of "I, speed, eradicate."

  • @npietref Right, sorry, "speed" is nom...so i guess it's best described as "I get rid. Quickness!" or something lol

  • Misaka can do better than that :)

  • @sophgirl1 Is that from an anime becaues that name sounds familiar.

  • @shawn963741 Yeah To aru Kagaku no railgun :)

  • Oh, joy. This is simply wonderful news. What a boon for humanity.

  • @music4pets Like GPS and the Internet, it really is a boon for humanity. Rockets require huge amounts of fuel because you need to burn fuel to lift the fuel. Our current launch vehicles are 97%-99% fuel by mass. So only 1%-3% of the energy consumed is used to lift payload.

    The two alternative launch technologies are gas guns and electromagnetic railguns. They launch only payload, no fuel. They could reduce launch costs 30-fold to 100-fold. From $5000 per kg into orbit to $50.

  • @music4pets Shaddup, hippie.

  • Looks like a cat, hilarious

  • This is important because screaming death is america's last important export. Rock On- Boy Scouts with machine guns. What could possibly go wrong.

  • So I guess if that projectile hit you, it might hurt you some....

  • in laymens terms.....the fire is there beacuse it's going so fast it catches air on fire...

  • How is possible to be electromagnetic, when I see fire everywhere? I mean, if there is fire, it's a regular shot isn't it??

  • @Vladamor the fire is there cause the projetile is moving so fast it catches the air on fire! in really short form its friction...

  • @Vladamor the fire comes from the plasma armature that holds the projectile. When a really high current passes through the plasma armature, it ionizes and the Lorentz force from the electromagnets push the plasma out along with the projectile. The "fire" you see is the plasma.

  • Sooo this thing shoots metal?!?! I don't understand

  • @ChristianA1803 a system that shoots a fragment of metal at supersonic speeds using electromagnets. Theoretically it could be used to bomb enemy bases thousands of miles away from a fleet of battleships.

  • I machine the projectiles for this gun!!!!

  • HOW DOES THE CAMERA MOVE SO FAST?!

  • @beer94

    last part is obviously CGI.

  • @chiefbyfire you realize that this research will eventually lead to the development of mass drivers that will enable us to cheaply launch vehicles in outer space right? This thing have a potential to bring us one step closer to utilizing the pile of resources lying there and solve such unimportant issues such as scarcity of resources.

  • @DaniOcean Well, might, potentially. But I think he's right, the fist application of this technology will probably be on battleships. That's not the technology's fault though. Anything will find use as a weapon first if it's capable of killing cost-efficiently. That's the key aspect.

  • 0:17 reminds me of the time my friend and I tried to make macaroni for the first time.

  • Just mount that on a spaceship....BOOM FRIGATE!!!!

  • wouldent the camera following this thing break the sound barier lol wtf how is it following it.

  • @77negie77 it's just using zoom and turning around lol ;)

  • Even though this is intended as a weapon, it might be able to be used as transport. All you need to do is slow it down so cargo won,t be crushed by the G forces

  • I think this video's comment section has the most youtube arguments I've come across :D Know it all trolls are the worst.

  • Id like to remidn all commentators here that this was the device shooting at about half it's full muzzle velocity-about 2500 m/s, not the full 5500 m/s plus

  • For halo fans, would anyone consider this a MAC cannon? or is it just a railgun? or is there a difference?

  • @funnyvidsmaster12 pretty much the mac cannons from halo are only bigger

  • @funnyvidsmaster12 mac cannon are rail gun

  • No ships also have the ability to track low orbit/upper atmosphere objects like ICBMs, Air defense destroyers with RADAR like the S1850M can track ICBMs.

  • Why is there fire after the projectile fires if this gun is electromagnetic?

  • @kablamo13 The friction from the projectile rips the air and turns it into plasma.

  • wierd bullet

  • Best murder weapon in the world... you don't even have to care about body dispersal :D

  • i'm confused at what the purpose of this is. it doesn't seem like a gun as much a mortar.

  • @HarderRocker15 That's basically what it is, it's ment to be fired from long distances and still deliver enough kenitic energy to destroy a target without using any explosives. In other words, it's badass and don't stand in front of it.

  • @brokenglass12 It's "Kinetic" btw.

  • @jeppewie1206 Oh well, all the letters are there at least, just gotta switch them around a little.

  • i hear this tech is going into airfields to decease the space needed for planes to take off. pretty cool.

  • Now, lets see them hit the UFO's on the dark side of the moon. Now that would be a feat.

  • 0:30 I thought that was a duck i was like ohh sad.

  • @XmojotronX I do XD

  • Just for people who don't know the science behind it. In its simplest it makes a magnetic field that moves the object forward. The fire is not from a rocket the projectile is simply a piece of metal with no thrusters. The fire is caused by the friction between the air and projectile.

  • @5dstrix I take that as a compliment. Go away republican.

  • hmm.. why so much fire at shoot?? why absent the meeting of that bullet with target?! there is no iterest how it flyes!! Most interest is what will happens with target!!

  • Problem 1. The Barrel wears out after a few shots.

    Problem 2. Their using a factory to contain it.

  • @Kofwan Solution 1. Its intended to fire nuclear warheads without the need for a ballistic missile. If you need more than one shot the world is ending anyways.

    Solution 2. The current design is intended to be put onto a massive warship that is already being built.

  • @Lonewolf6565 It's intended to replace ground target missiles. Shooting a warhead is only needed in a nuclear war. And in a nuclear war several nuclear weapons would be needed. Unless the barrel is massive.

  • @Lonewolf6565 Your Solution 1: Completely wrong

    Your Solution 2: Mostly wrong

    It's intended to replace the normal large guns on destroyers, the ammunition would have no powder in it so it could be lighter and easier to handle. On top of that since it moves so much faster, it's more accurate and able to travel farther.

  • @davidsirritation really now.. you do realize it wont replace anything. They are building an entire destroyer just to keep ONE. and YES its original conception was an idea to fire ballistic warheads through means that didnt require a missile that could be tracked by radar. the components required to fire just one of them fills an entire warehouse. just putting three of the things on a ship would demand that it be the size of an aircraft carrier.

  • @Lonewolf6565 What you're referring to is the DD(X) class of ships which are nuclear powered destroyers, with the capability of shifting power from the engineering systems to the weapons systems and back seemlessly. Also this is a test system, a functional system would be scaled down. Also your comment about missiles being tracked by radar is completely ignorant. Radar doesn't track so well in outerspace which is where ICBMs are launched to, not over ground.

  • @davidsirritation is that so? well i guess we will never know just how they manage to detect missile launches...

  • @Lonewolf6565 Yea if only there was some sort of technology that allowed us to see things on Earth from space...

  • @davidsirritation Of course RADAR works as well in space as it does in an atmosphere, The technology is so easily available now that air defense destroyers carry RADAR that can track ICBMs in flight.

  • @Tuberuser187 Again look into what you're talking about. A little knowledge of physics will tell you that even light waves move faster through a vacuum (like outer space) than through air. So radio waves have a limited range, since they are after all energy and as they move they expend that energy. Also RADAR works on basically a tranceiver emitting radio waves and receiving them back at specific intervals to get an idea of how far something is based on the time it took to get a return.

  • @davidsirritation Ok so you managed to pass junior level physics but still you manage to forget that modern RADAR systems easily compensate for any variance in wave impedance.

    RADAR is used constantly in space, its used to track satellites and debris and used by the ISS for docking procedures. The most sophisticated space track systems Large Phase Array RADAR can be up to 100 times more sensitive than aircraft tracking systems and can track objects as small as 10cm from over 5000km away.

  • @Tuberuser187 Right you're talking about large stationary systems or systems that are on satellites. He was talking about systems that are used on ships. Those will in no way be able to track an ICBM. Check out a Jane's manual sometime. The types of radars being used really aren't that powerful because they don't need to be.

  • What kind of camera setup is used to capture that panning shot of the flying projectile??? Impressive.

  • what damage does it do?

  • @1bigbottom Belive the damage is kills everything.

  • And thats just a block, imagine if the projectile was more aerodynamic!

  • @zmarine44 Holy crap...that's alot of power!!! equivelant to a nuclear explosion though? really? sure you're not just pulling my leg?

  • @SnoozersDog it's not more powerful than a nuclear explosion, he's an idiot.

  • @SnoozersDog to put it in perspective... 33Mega Joules (the energy from this projectile) is like 66000lbs of material crashing into something at 100 mph. A lot of energy, but not a nuclear weapon. This let off 33 Mega Joules... or 33x10^6. Hiroshima let off 6.4x10^13 joules. 33000000 Joules (the gun) < 64000000000000 Joules (Hiroshima)

  • @ComradeNerd Ok you didn't have to explain that much to me, I'm not a total moron, I'm smarter than my 9th grade sister and I'm in 6th and she's an A-Plus student...

  • i see no one will be happy with this until everyone has a railgun. then no one will be happy cuz everyone will have a gun that shoots a 33 megajoule shot. then everyone will want to disarm everyone from the awesome railgun. then everyone will be mad. than, Come@mebro

  • Projectile: "WEEEEEEEEEEEEEEEEEEEEEEEEEEEE­EEEEEEEEEE!!!"

  • Absolutly stupid weapons . Or Im crazy ..

  • Comment removed

  • yeah! misaka mikoto!!

  • @MrGaky

    Do you know how big 16 inch cannons are? I'll give you a hint; not 16 inches.

  • @mostly perfect

    We don't use battle ships anymore. All have been decommissioned. Not as effective as aircraft carriers. As for rail guns, imagine that projectile hitting caves that insurgents are hiding in.

  • What they didn't show was the reason why he left that fast... Had to get the pancake mix only to find... Yup you guessed it THEY AIN'T GOT NO PANCAKE MIX!!!!!

  • hmm... this is very illustrative, I haven't thought of railguns looking like this in real life when reading Science Fiction.

  • You need a hole factory to shot this gun.

    THAT WILL WORK ON THE FIELD =D

  • Why not just use rocket?

  • @Civsuccess2 Rockets are EXPENSIVE and take up a lot of room on a battle ship. They're also dangerous to the crew and can explode when the battle ship gets hit. This railgun cannon packs just as much explosive power and range, only needs a hunk of metal and electricity to fire, and can be fired quickly and repeatedly.

  • @Civsuccess2 You mean a missile, rockets are unguided and are thus very inaccurate. Cruise missiles are much more expensive. Just one can cost several million dollars for a single missile. If you are trying to kill some guys living in a tent, it's very cost inefficient. For a railgun, the cost is dirt cheap. Plus it has the advantage of firing numerous projectiles (which are much smaller so it can carry more ammo), and the transit time is much shorter since the projectile moves faster.

  • That would make a good mech warrior sniper rifle

  • I like chicken

    

  • use it on a satellite... or a large Plane... or just something nice enough not to fly off in the other direction after shooting it...

  • I want to see it hit something.

  • Hello #UN# how are you? How are you today?

  • Just to give some perspective to the speeds we're talking about here; during the interval between 0:23-0:27, the timer to the bottom left goes from 16:49:46.190 to 16:49:46.213 which means that those 4 seconds are actually just 23 milliseconds. I want that camera.

  • That looks like when I take a shit.

  • murder has never been to futuristic.

  • The US gets all the best toys

  • @Misterwhalley88 Just wait till it gets sold to another country that will end up selling it to a another country and so on and so on.

  • America never stops surprising me. Always inventing newer and more expensive ways to kill darkies and take their national assets.

  • @Rssika As it should be.

  • fuck this shit

  • Useless if the video doesn't show a cow exploding from it.

  • Anyone relating this to a video game, especially the newer Call of Duty series, should kill theirselves immediately.

  • @kalamari13 themselves

  • @kalamari13

    I'll be the guy you hate-

    In the game S.T.A.L.K.E.R.: Call of Pripyat, they actually designed a level (An underground lab) based on the laboratory this video was taken in. You can actually walk around the railgun.

  • @kalamari13 think anyone with spelling like that should kill "theirselves" immediately

  • @kalamari13

    >Railgun

    QUAKE!

  • @kalamari13 What about Red Faction? They have a rail gun in that.

  • @kalamari13 Well apart from gause rifles in battletech maybe.

  • @kalamari13 What should people who can't use the word themselves correctly do with themselves?

  • @SpellboundSolution

    Invent time travel and retake high school to eventually NOT having an in-home job.

  • @kalamari13 How do I used tense? Seriously, where the hell did you learn English?

    You like My Little Pony, so basically anything you say is irrelevant. Your the equivalent to a block of lard, or a pile of gerbil corpses.

  • Comment removed

  • @SpellboundSolution

    Your credibility is worse than that of a furry, a mentally impaired man/woman, an internet-dwelling Brazilian, a newly immigrated south-eastern Asian woman driving on a busy American interstate.

    You're literally a subhuman shitheel, being an Adult Male, for watching and chronically masturbating to a television series specifically directed and geared towards female <12 year old children.

  • Comment removed

  • @kalamari13

    I agree, well said.

  • @kalamari13 QUAKE3, Eat your heart out!!!!!

  • @kalamari13 Why is that?

  • @kalamari13 themselves* OHHHH you just got grammar'd

  • "a railgun that accelerates a 3.2 kg (7 pound) projectile to 2.4 kilometers per second (7,875 feet per second)"

    thats how fast it goes.

  • Impossible not to love that blue fire it leaves... when you are in the right point of the gun obviously =p Go Railguns Go! Thanks to this we're talking toward rail propelled space shuttles =p Cheaper space travel ftw

  • @isokessu because its bad ass

  • 1) By saying "your government" it sounds like you don't even live here, and 2) What is your address so we can further calibrate the targeting system.

  • @isokessu

    while I agree that our country has some serious misappropriation issues, without research such as this, advances in science are not possible.

  • @5dstrix But why does it have to be used in a fucking weapon? Why not a new space shuttle?

  • @madjimms I would argue that the technology used in this "weapon" (which will very likely never take a human life, due to it's complexity) will likely see use in a plethora of developing technologies. With our boneheaded leader curtailing our space program, it is unlikely that any federally funded non-military spacecraft will benefit, however that doesn't mean that the physics and research will not help to advance any relevant developments in any "free-market" projects. Science, my friend.

  • @5dstrix Less boneheaded than the last one.

    Fuck free market.

  • @5dstrix true... to better accomidate railguns, you need better and smaller energy storing devices, a breakthrough here could translate instantly to civil applications.

  • @isokessu I'd still rather live in our shitty country than your shitty country, but thanks.

  • @isokessu

    Of the thousands of horrible things that you could have picked on the US for (and entirely justifiably so) you picked this? Linear Magnetic Acceleration technology is your target? I want them to expand this technology and have them use mass drivers to launch stuff into orbit so we can start mining asteroids. You want to talk about helping the third world out, talk about what would happen if raw materials only cost pennies.

  • @sornyninja If we ever mine asteroids, it certainly won't be in any of our lifetimes. The asteroid belt is really far away and there's no money to speak of going towards developing faster space travel (not to mention the fact that the ship would need to be absolutely *massive* to acquire enough materials to justify the cost).

  • @isokessu Because Americans do not need the government holding everyone's hands. We want LESS government handouts to lazy bastards. I'd much rather see my tax money go toward defense or nasa than to welfare checks.

  • can someone please explain what just happened?

  • @jawbraeka

    A piece of metal was forced to accelerate by an electromagnetic field. The exact speed is not mentioned in this video. But it was faster than anything accelerated by explosives, such as gunpowder. Therefore new world record, but that's from 2008, go figure.

  • @jawbraeka A hunk of metal was loaded in between two 33 megajoules electro magnets. The magnets pulled the metal down the barrel with so much force that when it launched out the end it was moving at mach 5. That's 5 times the speed of sound. A megajoules is a unit of energy. It takes one megajoules of energy to launch a semi truck down the interstate at 100 miles per hour. Being hit by this thing is like being hit by 33 speeding semi trucks and it uses no expensive rocket fuel or explosives.

  • @MostlyPerfect That means that we could technically have pigs flying by the end of this century.... awesome

  • Seems like the equipment is put under a tremendous amount of strain when firing. It doesn't seem to be very durable at this point, and the power lag is a problem. But it will be interesting to see going forward. This is the future of modern warfare afterall.

  • @vejet it's for tactical strikes so this is no problem

  • #LOL

  • They wanna use this in ships? Yeah right ... I know where this is going ... "Metal Gear?!! It can't be !!!" :-))

  • There Are Guns And There Are Rockets... This Is A Rocket

  • @koolittlekid in ballistics, rockets by definition have their own engine, this is a solid projectile and is therefore a projectile/bullet

  • @zythepsarian Alright smart ass you know what i mean. its fast.

  • omg, so big, in Russia much smaller aggregate )

  • E=MC2  simple really

  • that logo in the end scared me more than the gun itself....

  • thats just fucking dumb..... whats the point honestly... and @ AirCalv megan fox is a whore

  • @bunjicykd your just a troll..... whats the point honestly... and @bunjicykd trolls are whores

  • cannon ball of the future.

  • @chillz27 It's the sabot. It's a casing that goes around a shell to allow it to fill a barrel. It also prevents tumbling or alignment issues in the barrel.

  • dear mythbusters ,

  • SCIENCE

  • thats my heart after being kissed by megan fox on the cheek

  • at 17 seconds there is a frame where there is a lilac-white... thing floating above the end of the tunnel, anyone know what that is or is it just the camera playing tricks?
