Navy Tests Incredible Sci-Fi Weapon

The U.S. Navy recently 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. The test-firing, captured on video, took place Jan. 31 in Dahlgren, Va., and Navy officials called it the "world's most powerful electromagnetic railgun." The Navy's current MK 45 five-inch gun, by contrast, has a range of less than 23 miles (37 kilometers). The railgun has been a featured weapon in many science fiction universes, such as the new "Battlestar Galactic" series. It has also achieved newfound popularity among the 20-something-and-under generation for its devastating ability to instantaneously shoot a "slug" through walls and through multiple enemies in video games such as the "Quake" series of first person shooters. The Navy's motivation? Simple destruction. The railgun's high-velocity projectile will destroy targets with sheer kinetic energy rather than with conventional explosives.
