The Navy's Giant New Electric Railgun

a reply to: punkinworks10

Then there is that pesky thing called Newtonian physics, for every action, there is an opposite and equal reaction. Can't get around that

I think you miss the point of a rail or coil gun. There is no recoil. The shell is propelled by magnetic fields. There is nothing pushing back as it were.

As a hand weapon, I agree, not possible without some major discoveries although there are a few interesting smaller models out there. Try Youtube.

Umm , no
Unless you can carry a 100 mega watt generator around , along with car sized capacitors.

Ummm yes I went looking around and here are a few there are tons of them on the internets even 3d printed ones, all powerful enough to kill. . . .

Not the same thing at all.
The 3d printed one that all over the web right now,
only fires the projectile at 830feet/sec., that's only 60 feet/sec. more than my childhood .177" caliber pump BB gun, and 100ft/sec LESS than my 5mm pellet gun.
Unless you hit someone right center of the eye at 20 ft , it ain't killing no one.
It will deliver less than a quarter of the energy of a .22.

That's a long way from the navy's gun.


It has taken 30 years of development from the first railgun, built at Lawrence Livermore(I know some one who worked on it) to get where the Navy is today. The first one fired a 10mm dia lexan plug at 23,000 ft/sec, but it used the same amount of electricity as the city of Livermore did in a day , for one shot.

I did something I rarely do, watch a YouTube vid on ats, as they are usually lame.
So I watched the ones you posted, and guess what they were lame.
The last one is not even rail or coil guns. They are custom built match shooting guns , THEY USE GUNPOWDER. you can even see the cartridges, they look like 22-.250's or maybe hornet rounds, not up on current match shooting.
The other two are so low power they are using cardboard as a backstop, and they aren't even getting full penetration at less than twenty feet, I'm one you can even see the projectile bouncing back at the shooter.
Sorry no rail guns for you,

I imagine these may be devastating if used from space!

I wonder how difficult it would be to put one of these rail guns in orbit?

Also they could fire massive space rocks as ammo!

Centauri Prime commits genocide by orbital mass driver bombardment of the Narn Homeworld. Londo loses his soul:

Why spend money on this, tens of thousands of veterans are homeless and the government does nothing about it.

Update.

This video is from the commissioning of the rail gun, November 17, 2016. It was released by the Office of Naval Research and Naval Surface Warfare Center, Dahlgren Division, (where it was fired) three days ago (March 2017).

I did not see the projectile until they slowed it down! Nice to see the BAE logo on thing! Range of Mach 6 to 10 is kind of insane as is 250 miles. I like the shipping container full of capacitors!

Go 'Merica!

I'm sure it's a waste of money.

The only downside I can see is possibly missing your target due to the path the projectile takes against the curve of the earth.

Not sure if simply depressing the gun would be enough to bring it on target and, reducing the charge would negate the hitting power.


Other than that, I love this tech.

More money spent on violence! Why don't you give everyone a place to live, clean water, decent food, fuel to heat their homes and free medical care? Social Security is allegedly in the crapper and we can spend money on better ways to kill our fellow human being?

If you do that, all the people do is breed and then you have an exponential growth in your welfare kings and queens... We tried that with Lydon B. Johnson and the cancellation of the Apollo program. Why spend all that money going to the moon when we have poor and helpless people right here on earth that are needy..

Anything that will give our country an edge over an enemy is something any country should be happy with... The only qualm I have is the amount of money the bastards charge for their latest gizmos.

Yayy the awesome rail gun that has been 20 years away from military service since BEFORE fusion was 20 years away from generating commercial power...

P.S: They picked this gigantic waste of effing money over an ACTUALLY WORKING TECHNOLOGY aka the combustion light gas gun which if it weren't for this piece of S*** we'd have had the first zumwalt class equipped with straight out of the shipyard.

That's right folks, they defunded an actual program that had borne fruit to focus on this giant time energy and money sucking bag of flaming dog s***!


Oh and helpful hint:

If you think railguns have no recoil.... Take the guards off your electric fan, place guard less fan in your lap while naked, and hit the power switch!!!

Because you shouldn't be allowed to breed if you're genuinely that monumentally stupid!

Hint 2: rail guns are essentially an "unrolled" electric motor with it's various elements arranged in a straight line.

The reason that guided ammunition is impractical is the fact that the railgun creates a small but very very powerful EMP pulse field around the projectile.
This would burn out any electronics in the guidance system.

Not at all. In fact, they do have guided shells, they just dance around it in the MSM.

And it's not an EMP. Not every energetic electromagnetic phenomenon is an EMP. It's getting to be like "hologram", the term is cruelly abused.

I imagine them using this technology for directed energy at some point in the future.

Why? It isn't relevant to that.

What you're looking for is the FEL department, two doors down on the left.

He's quite right. There is always recoil. And a rail gun has plenty. In fact, it's one of the primary failure modes - the windings on the rail mechanism deform and short due to kickback from the shell.

Hint - momentum is conserved

As in every action has an opposite reaction? I can live with that, is it air pressure that creates the kick, the sound barrier or some other type of science?

Enough electric charge to kill a bull and he manages to turn it into a projectile able to break a lightbulb...i am not convinced.

I remember watching a good you tube video on how you need to make electronic circuits able to survive something like 15,000 g forces!

Also, there was something like a 95% hit rate within 4 meters of target over 50KM

I wonder if there are many stockpiled in SK.
