Electromagnetic (EM) Railgun &file=" /> Electromagnetic Railgun World Record Shot on December 10, 2010   The Office of Naval Research (ONR) sponsored Electromagnetic (EM) Railgun Innovative Naval Prototype will deliver hypervelocity projectiles 200 nautical miles (nmi) at a muzzle velocity of Mach 7.5. The EM Railgun uses high-power electromagnetic energy instead of explosive chemical propellants (energetics) to propel a projectile farther and faster than any preceding gun. The safety aspect of the Railgun is one of the greatest potential advantages of program. No propellant is required to fire the projectile, and no explosive rounds are stored in the ship’s magazine. On December 10, 2010, the U.S. Navy made history at the Naval Surface Warfare Center-Dahlgren Division with the BAE Systems developed Laboratory Railgun. A 33-Megajoule shot was fired, the energy equivalent of 110 nmi range.
