Electromagnetic Rail Gun
A railgun fires projectiles using electricity instead of chemical propellants. Magnetic fields created by strong electrical currents accelerate a sliding metal conductor between two rails to launch projectiles at about 7,200 to 9,000 kilometers per hour, compared to perhaps 5,400 kilometers per hour for a conventional gun. By equipping ships with railguns rather than standard artillery, the Navy could eliminate the hazards of having high explosives on board ships.
