U.S. Navy Invents Railgun

The mighty railgun, that hitherto-unfeasible weapon most beloved of gamers and geeks the world over, is now a functional reality thanks to the U.S. Navy, which has produced a working 8-megajoule electromagnetic mass driver.

Spotted at the Naval Surface Warfare Center in Virginia, the navy's new weapon of choice fires but a single shot at once, unlike the hypothetical counterpart featured in classic FPS Quake. But what a shot is is, offering a 250 nautical-mile range (with an apogee of 95 miles from the Earth's surface!) and enough kinetic energy to equal the destructive power of a million-dollar missile.
