The U.S. Navy has test fired a weapon straight out of a science fiction film called a rail gun. The weapon weapon can hit a target 100 miles or more away within minutes.
The military has been testing the weaponery and technology behind it for years. Electomagnetic current accelerates a non-explosive bullet at several times the speed of sound. The conductive projectile zips along a set of electrically charged rails and out of the barrel at speeds up to Mach 7.
The weapon generates so much heat it can melt the components inside.
