This link will take you to a web article by Telegraph that talks about a new weapon that is under testing to be used by the United States Navy. This new "Rail Gun" uses electromagnets and electric current to fire projectiles at about 5,600 mph! That was no typo, it is 7 times the speed of sound. This new will weapon will be able to hit targets up to 220 miles compared to the guns used now that have a effective range of 15 miles.
