Here are some photos of the Navy testing its new electromagnetic railgun at the Naval Surface Warfare Center. The railgun fires at 10.44 megajoules, with a muzzle velocity of 2520 meters per second. Click through for more details and a gallery of splodey pics.

Future Navy ships will use electric drive propulsion, making the electric-powered railgun possible. The railgun sends current along parallel rails, creating an electromagnetic force so powerful, it can shoot a metal projectile at record-breaking speeds. Photos by AP/U.S. Navy, John F.
