Project Thor: applied the concept of kinetic bombardment to a global first-strike capable system. The weapon relied on 1'x20' tungsten carbide cylinders that could be forcibly de-orbited with pinpoint precision. Traveling at over 10 times the speed of sound, the kinetic energy released on impact would be equivalent to a small nuke and be capable of destroying bunkers far underground.
kinetic energy achieved by the rods falling to Earth. Despite this, the weapons theoretically could have a payload equal to that of a nuclear bomb, without any of the nasty nuclear fallout, since they’d be able to reach speeds upwards of Mach 10.
Kinetic bombardment. If you’ve seen Die Another Day, then you probably know what kinetic bombardment is all about. For those of you who haven’t seen the film just imagine the development of an international space weapon-satellite that can destroy anything on earth within a couple of seconds. Kind of scary, no?
