Wouldn't you have the upper hand if you had a small hovering robot that was capable of shooting down enemy ballistic missiles? While it sounds like science fiction - it's a reality. Meet the Multiple Kill Vehicle, a fast hovering robot that looks like something out of the Terminator movies. The Multiple Kill Vehicle or MKV for short, lifts off the ground moves left and right, and rapidly firing all while shooting thrusters on its bottom and sides for navigation.
The idea is to mount one or more MKV onto carrier missiles which could then be launched into space to engage enemy nuclear-tipped ballistic missiles at their peak or their trajectory arcs. This would be the highest point of the missile and could be safely destroyed at such heights.
Once in space, the MKV would break away from the carrier vehicle and then use highly accurate targeting computers to shoot kinetic interceptors to destroy enemy warheads before they drop down to Earth.
