"Navy scientists with the Office of Naval Research (ONR) hit a new milestone, successfully firing their electromagnetic railgun for the 1,000th time as the state-of-the-art weapon edges closer to real world deployment.
A theoretical dream for decades, the railgun is unlike any other weapon used in warfare. And though still in testing, it's quite real, as the U.S. Navy proved in a record-setting test Monday, Oct. 31, in Dahlgren, Va.
Rather than relying on a explosion to fire a projectile, it uses an electomagnetic current to accelerate a non-explosive bullet at several times the speed of sound. The conductive projectile zips along a set of electrically charged parallel rails and out of the barrel at speeds up to Mach 7."
