Reposted because this was deleted when posted in the original thread as a update.BATH, Maine (AP) — The U.S. Navy pulled the plug, for now, on a futuristic weapon that fires projectiles at up to seven times the speed of sound using electricity.
The Navy spent more than a decade developing the electromagnetic railgun and once considered putting them on the stealthy new Zumwalt-class destroyers built at Maine’s Bath Iron Works.

All told, the Navy spent about $500 million on research and development, according to Bryan Clark, an analyst at the Hudson Institute.

But there were a number of problems. Those included the range of about 110 miles in testing. A Navy vessel could not employ the gun without putting itself within range of a barrage of enemy missiles. And its usefulness for missile defense was also limited by range and rate of fire, Clark said.
