Flying Crowbars


We tested the US Military’s secret space weapon
Veritasium

I first came across the idea of using heavy metal rods dropped from space as a weapon in Footfall, a science fiction novel by Larry Niven and Jerry Pournelle. It sounded like a great idea, simple, inexpensive and devastatingly effective. Derek tries to demonstrate it but fails. He might have done better with some kind of guidance system and some steerable fins. However, while there might be cases where it could be useful, he goes on to explain that for any of the proposed uses, it's not going to be all that effective. I think the biggest objection is that pound for pound, nuclear weapons are much more devastating. An ICBM might carry a ten ton payload. That would be enough to launch one big tungsten rod or half a dozen nuclear weapons. And while you aren't going to get any radioactive fallout from a ten ton kinetic weapon, I'm not sure that argument will carry any weight when you are bent on destroying your enemy.

Take SpaceX's 1st stage re-entry guidance package, and mate it with tungsten rods 1/2 the size of telelphone poles, and put them into a deployment platfrom in orbit.
