US Navy receives EM railgun prototype

The US Navy (USN) has taken delivery and started testing a prototype electromagnetic (EM) railgun from BAE Systems as the service continues to develop a surface ship gun that can fire a projectile 50-100 n miles (93-185 km) without using propellants. General Atomics is due to deliver its competing prototype to the USN's Office of Naval Research (ONR) in April
