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.
