Cool new toy

Navy builds railgun

The U.S. Navy yesterday test fired an incredibly powerful new big gun designed to replace conventional weaponry aboard ships. Sci-fi fans will recognize its awesome power and futuristic technology. The big gun uses electromagnetic energy instead of explosive chemical propellants to fire a projectile farther and faster. The railgun, as it is called, will ultimately fire a projectile more than 230 miles (370 kilometers) with a muzzle velocity seven times the speed of sound (Mach 7) and a velocity of Mach 5 at impact
