  military railgun test weapons

A weapons test at the Naval Surface Warface Centre made the news yesterday because a heretofore novel device was successfully tested: A railgun, more technically referred to as a Gauss-effect linear accelerator. Railguns are, conceptually, pretty simple devices: A ferrous projective rests inside a set of conductive metal rails, through which an electric current passes. When a sufficiently large pulse of electricity passes through the rails, the projectile goes out of the business end of the device at high velocity. Whatever is hit by the projectile either ceases to exist or has a very, very large hole through it due …
