NAVAL SURFACE WARFARE CENTER DAHLGREN, Va (Dec. 10, 2010) The Office of Naval Research Electromagnetic Railgun located at the Naval Surface Warfare Center Dahlgren Division, fired a world-record setting 33 mega-joule shot, breaking the previous record established Jan. 31, 2008. The railgun is a long-range, high-energy gun launch system that uses electricity rather than gunpowder or rocket motors to launch projectiles capable of striking a target at a range of more than 200 nautical miles with Mach 7 velocity. A future tactical railgun will hit targets at ranges almost 20 times farther than conventional surface ship combat systems. (US Navy video/Released)
