DAHLGREN, Virginia — There wasn’t much left of the 23-pound bullet, just a scalded piece of squat metal. That’s what happens when an enormous electromagnetic gun sends its ammo rocketing 5,500 feet in a single second.

The gun that fired the bullet is the Navy’s experimental railgun. The gun has no moving parts or propellants — just a king-sized burst of energy that sends a projectile flying. And today its parents at the Office of Naval Research sent 33 megajoules through it, setting a new world record and making it the most powerful railgun ever developed.

Reporters were invited to watch the test at the Dalghren Naval Surface Warfare Center. A tangle of two-inch thick coaxial cables hooked up to stacks of refrigerator-sized capacitors took five minutes to power juice into a gun the size of a schoolbus built in a warehouse. With a 1.5-million-ampere spark of light and a boom audible in a room 50 feet away, the bullet left the gun at a speed of Mach 8.

All that energy was “dump[ed] in 10 milliseconds,” says Charles Garrett, project manager at Dahlgren for the railgun.

I wonder what the range is? :cool:

I bet youse guys could keep the Australians at bay with that - huh?

Heck fire, Uncle Jed - you've only gotta fire it once a day for effect!

1160993 2010-12-12 11:20:00 We don't need guns to keep the Aussies at bay. We just say 3 words...

"Pavlova"

"Phar Lap"

1160994 2010-12-12 17:22:00 mach 8, dang that could be some serious AA weapon, AWAC's wouldn't even see it coming to advise

Why does the US get all the cool toys for Christmas? They get a rail gun, we get budget week reports :p

1160996 2010-12-12 20:56:00 The American Navy already have a very successful railgun mounted on a battleship IIRC.

I know.

I saw it used in the Transformers movie! :D
