U.S. Navy photo Dec. 10, 2010, of a world-record setting 33 mega-joule Electromagnetic Railgun shot, breaking the previous record established Jan. 31, 2008. The Office of Naval Research system is being designed for a long-range, high-energy gun 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, according to the Navy.
