(Bloomberg)   The Navy tests a new weapon that can fire a projectile 126 miles. Did I mention it's an unpowered solid projectile traveling at 5,600mph, or Mach 7? With video awesomeness   (bloomberg.com) divider line

It's a rail gun. They've had these for years.  The trick is getting enough power stored to fire the projectile and making a projectile strong enough to survive the launch without deformation.  You're looking at getting something up to 5600 mph in less than 100 feet.

Lsherm: making a projectile strong enough to survive the launch without deformation


The video mentions each projectile costs a ton of money. I wonder what they're made of -- tungsten, maybe?

It would also be nice to be able to fire repeatedly w/o melting the gun

They're not just solid slugs. They have crap in them, apparently.

I don't like the idea of 10,000 tungsten cubes hitting anything ever. Not one bit.

Tungsten shell, depleted uranium core- the DU is self-pyretic meaning it doesn't need an explosive to burn through anything.  There's some cool home made rail guns on Youtube if you'd like to build one of your own- so far, they're not very powerful- if they ever become 3 or 4 times more powerfull, they'll be as powerful as a 9mm pistol

Oh, goody! All the kinetic energy you can deliver, at a fraction of the cost of a suitcase nuke! Just what we needed, the newest way to throw a rock!

Nuclear-powered ship, carrying weapons that have no recoil and which can deliver a projectile that has no propellant, no explosive, and can blow through the best physical defenses. Yeah. I'm looking so forward to the next arms race - except no one else is racing us. It's as if we're gearing up to take over the friggin' world in 30 years.

Magnetically launched projectiles have recoil.  The means of pushing the projectile is different, but it's still one thing pushing really hard against another.

More accurately, they've been building these damned things for years, in various forms. The problems (which still exist with this one) are repeated firings, range, energy use, and a bunch of other stuff (ok, so apparently they knocked off the latter two).  Hell, this was explained in my 8th grade science class (magnetic wave timing) when we were talking about how electric motors/generators work.  And I'm 30 now, and could probably find it in some scifi from the 50s too.  This isn't new any more than pointy sticks is.

The only news is the progress. It's been a dream for as long as I've been alive, in one form or another, and I'm a bit older than you. I just wish we'd focus on EM propulsion as a launch vehicle, not as a weapon delivery system.

Serious question: what would you  target with one of these that makes it a better choice than existing weapons?

And how do we defend our supercarriers against them when, say, China has them too?

The kinetic energy of one of the projectiles is about the same or greater than the explosive energy of the missiles of the same range with greater penetration.

I would think you have to defend against a rail projectile with your own rail projectile if you can get a shot off fast enough.

Near useless weapon. No explosives because the g-force involved at launch meaning that you have to hit it.  Good luck on hitting planes with no proximity fuse even at 5600mph. Good luck destroying reinforced structures. Oh and here is one.. it's just a big block of metal at it's maximum range falling at terminal velocity meaning it has lost most all its kinetic energy.

OK, I understand that. But I still don't know what we would fire it at. I don't even know what we'd fire existing cruise missiles at that is more valuable than the ordinance we use up. (Sometimes I feel like we should stay home, give the Taliban the cost of our ammunition, and call it even.)

Yeah, good luck with that. Maybe shrapnel clouds?

At above something like Mach 3, kinetic energy equals the explosive energy of projectile's weight in TNT.

But the projectiles are just blocks of metal.  A room full of metal won't explode if the ship's on fire.  IIRC this is also why damn near everything military is turbine or Diesel powered, the fuel doesn't vaporize and explode, it just calmly burns.

  I can't read an article about a magnetic rail gun without thinking of MW's Gauss Rifle. I read somewhere not long ago about some scientists discovering a polymer that would shrink when an electric charge was applied so maybe myomer is right around the corner too.

The number is 3 kilometers per second, not mach 3 (which is roughly 1 kps).

You'd target anything a regular gun would work on, except you can target stuff a heck of a lot farther away.

As pointed out upthread, DU makes it's own fuel-air fireball when it passes through armor. This weapon is ideal for use against aircraft carriers.

And it shoots through schools.

I dare to assume you ignorant jackasses know that space is empty. Once you fire this hunk of metal, it keeps going till it hits something. That can be a ship, or the planet behind that ship. It might go off into deep space and hit somebody else in ten thousand years. If you pull the trigger on this, you are ruining someone's day, somewhere and sometime. That is why you check your damn targets! That is why you wait for the computer to give you a damn firing solution! That is why, Serviceman Chung, we do not 'eyeball it!' This is a weapon of mass destruction! You are not a cowboy shooting from the hip!

violentsalvation: Return of the battleship?


Battleships could lob in shells on an arc at a relatively high rate of fire.

Wouldn't this thing pretty much need line of sight, even BVR.

So we have a ship with an amazing anti ship weapon (flat ocean)  that is pretty much useless for ground support (they'll just position selves in defilade like behind a ridge). Not usable against air assets due to lack of guidance systems as well.

 Inability to do surgical. Strikes due to the line of sight issue as well.

So until they strap it on my nuclear  powered Mad Cat it seems impractical.

disregard my last. Space defense against the covenant with MAC cannons is worth it, but sort don't build the cannon platforms. Static defenses don't historically work.
