Don't stand in front of it!

Special delivery for the ancient denizens of The Arms Chest, from our bulging "Reach out and touch someone" file The Phantom Soapbox brings you: US Navy Rail Gun!

Navy scientists set a world record Friday during a test of an electromagnetic railgun, a tractor-trailer sized weapon that sends a 20-pound projectile rocketing through the air at seven times the speed of sound.
The futuristic gun was tested twice at the Naval Surface Warfare Center in Dahlgren, Va., and the first shot generated 33 megajoules of force out of the barrel, a world record for muzzle energy, the scientists said.

Their motto: velocitas eradico.

Oh yeah, baby.  Sign me up for one of these.  It won't fit in my truck, but I could tow it...
