WASHINGTON -- The phrase "faster than a speeding bullet" just took on a whole new meaning.
"An electromagnetic rail gun is a gun that uses just electricity -- no gun powder -- and, oh, by the way, can shoot a projectile like this, well over 100 miles at Mach 7," said Rear Adm. Matthew Klunder, the Chief of Naval Research, which developed the rail gun. "Seven times the speed of sound."

Another interesting thing is that the US Navy just revealed its state of the art futuristic Zumwalt-class ship which also has been designed to support the US Navy's railgun I just talked about.
Could this be the beginning of the second Cold War?
