The US Navy now has a rail gun.

...or at least they're testing one.

http://gizmodo.com/351467/navy-rail-gun-test-destroys-everything-it-touches-at-5640-mph

the 10-megajoule test fire launched it's 90mm projectile at 5,640mph.

wait, it gets better. this is only one third of the gun's 32-megajoule capacity.

ready? it gets better still. this gun's maximum power is only half of the target 64-megajoule capacity that the navy is aiming for.

the finished product is expected to be able to accurately hit a 5 meter target from 200 miles away. now, if you do the math, you'll realize that in it's current incarnation, that will take over 2 minutes. but. you crank that up to 64-megajoules, you'd theoretically be making it fire 6 times faster, and it should take about 21 seconds to hit the target.

the best part about the videos is that this thing is firing so fast that it looks it's using a chemical propellant to fire and that it has so much kinnetic energy that it looks like the projectile is explosive.

Very, very cool. Although the amount of power it seems to need would probably reserve it to nuclear-class battleships.

Plus, I'm glad something this powerful is being developed by the "drunk" part of the U.S. Military.

Interesting Tidbit: I talked to a navy recruiter the other day and he said I was qualified for nuclear management. Take that for what you will.

note to self, buy a bigger nerf gun than he used so it can have more power........
