The wait is OVER! Get your very own Railgun!
The only problem is it’s over 20 feet long, and takes a LOT of electricity to run, but hey, no annoying bodies to dispose of…
From the website:
Picture this: A massive destroyer receives the location coordinates of an enemy headquarters more than 200 miles away. Instead of launching a million-dollar Tomahawk cruise missile, it points a gun barrel in the direction of the target, diverts electric power from the ship’s engine to the gun turret, and launches a 3-foot-long, 40-pound projectile up a set of superconducting rails. The projectile leaves the barrel at hypersonic velocity Mach 7-plus exits the Earth’s atmosphere, re-enters under satellite guidance, and lands on the building less than six minutes later; its incredible velocity vaporizes the target with kinetic energy alone.
