a 33-megajoule firing -The Railgun Becomes Reality

...the Navy produced a 33-megajoule firing ....

A single megajoule is roughly equivalent to a 1-ton car traveling at 100 mph. Multiple that by

33 and you get a picture of what would happen when such a weapon hits a target....

A theoretical dream for decades, the railgun is unlike any other weapon used in warfare. And it's quite realtoo, as the U.S. Navy has proven in a record-setting test today in Dahlgren, VA.
Rather than relying on a explosion to fire a projectile, the technology uses an electomagnetic current to accelerate a non-explosive bullet at several times the speed of sound. The conductive projectile zips along a set of electrically charged parallel rails and out of the barrel at speeds up to Mach 7. 
The result: a weapon that can hit a target 100 miles or more away within minutes.....
