Sci-Fi RailGun, for real

December 10, 2010 - Demo video - World Record U.S. Navy. Projectile speeds - Electomagnetic current acceleration MACH 7 (1.712 km/h or 1064 mph) Distance: 100+ Miles (150+ km) GPS Accuracy. Current Navy guns reach 13 miles (21 km). A Single Tomahawk missile costs around $6 Million a Railgun projectile will cost a fraction of that. Fully functional rail guns are expected to be on Deck within the next 15 years. We will be hearing much more on this beast soon.

Wow, $6 millions for a single missile. 1,000 missiles makes it $6 billions. And for it to be in the deck on 15 years, how much will it cost? :O

Sweet! I never thought I was going to see this posted :D

Read the description guys, this gun is insane... it has GPS accuracy and they plan on being able to hit a certain target and use their own explosives/weapons against them...

The video you are seeing is a world record, the gun you see shooting is firing it out at 33 Megajoules..

If our Alien buddies do come to visit us soon... they better come in peace >:)

That was funny! It's like the Death Star charging up just to fire a 9mm round! >:)

Mach 7 is about 8,000 km/h (5,000 mph).

Obviously the further away the target, the slower the projectile, and the less impact it will have.

I wonder what the cycle time will be (cooldown, recharge, reload, fire).
I can see this on a carrier-type ship.

Pretty damm cool.

#9 - I believe the point is accuracy, effectiveness, and efficiency.

Think of it like treating cancer. It used to be that doctors would only be able to poison the whole body with chemo in the hope of killing off the bad stuff before too much damage was done to the rest. As technology progresses, they're getting better at isolating and attacking the problem, while leaving the rest of the body relatively unharmed.

Looked like the machine actually took some slight damage firing the projectile.

If Aliens are able to travel to planet earth then their weaponry will certainly be more powerful than ours O:)

This is cool but nothing like being behind a .50cal machine gun. Shooting 2 armor piercing, 2 armor piercing incendiary and the 5th round being a tracer to see where you are shooting at night. Watching two tracer rounds ricochet off of a wave top and straight up into the night sky.

A tomahawk missile costs 6 million. But what about the electric bill for running this beast? :)

This tech. doesn't have to be a weapon you know, what about un-manned mining robots in the asteroid belt using this kind of thing to fire ore back into earth orbit? Of course it has to start somewhere. I know most people don't like to hear it but with out weapons development we wouldn't have a fraction of the technologies we enjoy today.

#27 The rail gun is being designed to be used on nuclear powered ships that have almost unlimited electrical capabilities,so no worry about that. Since the Navy has now made major advances in the FEL (laser cannon) ,it might see action before the rail gun does.
