holy fuck... shoots projectiles at mach 7 over 100 miles. they plan to put them on battle ships in 2025. thoughts?

The projectile is completely inert so think of it as an electromagnetic BB gun.  Instead of using compressed air to propel it they use a series of electromagnets lining the barrel that become magnetized in an unbelievably fast sequence pushing the projectile forward.

I built one of these once, and shot a small hole in my wall. It's really the same idea, just small.

At that speed the targets that are 100 miles away would be dust in about 7 seconds thats fast

so the benefit is that the projectile can travel a much much greater distance at much higher speeds thus doing more damage?

Exactly.  It's damage comes from the pure kinetic force of impact rather than an explosive payload.

yup


The US gov also tossed around the same idea with orbital bombardment weaponry using giant tungsten rods the size of light poles. That shit would be fuckin gnarly.

execpt they realized it would create the same effect of a 10 magnitude earthquake but super localized and decided not to go there.

any video game with space in it anyone?

weapons aside, we could use it for transportation. if humans can survive that, then we could launch stuff off this planet without having to burn fuel, then burn fuel once we need to. And I guess if yo make it longer it can go faster, we looked at railguns in physics.

so that is hypothesized to be able to kill shit like double bad?

will it be used as like an anti-boat/air/tank gun?

I think the ones they're working with are unguided so it would probably just be stationary targets.

i guess you could hit moving stuff with it, it'd have to be computer controlled. If a fighter jet got hit by it, it would definitely explode, ships would sink, tanks would explode.

One of the biggest attractions on the Navy side for this weapons system is eliminating vessel's magazines (ammo stash) Its the most vunerable area on a fighting ship because of its campacity to explode if hit or on fire. All these projectiles would be inert thus more survivable and the pure power of the projectile will apparently give them the ability to smash through other ships reenforced magazines for a one shot kill.

Depends on the size of the projectile. No base or bunker would ever be safe though.



And to whoever said use it for travel....its been thought of. However the use of railguns and mass drivers takes a massive amount of electricity, especially if youre going to build one to replace rockets and such. Plus you would have to consider the G forces involved in this...

haha I was wondering the same thing. but it looks as though theres no electricity there, which you need to make a real railgun.

i am making one for science next semester. I will post up how it goes. also what is the ruler thing? how does it work. actually i think a railgun uses the projectile to link together 2 highly charged poles which creates a circuit and generates a massive electromagnetic field in front of the projectile. A coil gun uses magnets charging up in succesion. once this shit is armed the chinese don't stand a fucking chance.   I think we should put one is space that would be fucking awesome. just imagine we find the coororidinates of osama bin ladens cave and then we shoot a cannon call at it at mach 7. terrorists would bow down to the awesome power of a space gun.

^ what the fuck? wheres the video!?

how about personal railguns? instead of having soldiers carry ammo, carry batteries and shoot people. but i guess you'd still have to carry projectiles.

RAILGUN SNIPERS!!!11!!.

oh and

My physics teacher wanted to make one of these for a class project, but the school district wouldn't let him.
Talk about ruining a quality learning experience.

they've been "testing" railguns for like 20 years now, i'm almost positive they probably already have them deployed.

THE RULER THING IS NOT A RAILGUN!
damn, it's just annoying me to see it be referred to as one.
it is a GAUSS RIFLE

it's not at all the same thing and works in a very different way

yea really. If we've heard of it, and it's become general knowledge...odds are, they've been using it for years, and are probably already developing a replacement.

get your hands on some rare earth magnets, they should be plenty strong.
I think you can get them at most hardware stores but not entirely sure.
in Canada a store like Lee Valley is great for that sort of thing.. they have quite high quality ones

The only reason the navy ones are so complicated is because they run off electromagnets, which can be hundreds of times stronger than regular magnets.

So generally, it's the same idea with many magnets lined up.
