How come we dont have satellites that drop tungsten rods like bombs? Seems it would work.

Why tungsten if I may be so bold?

RJ805: Anything else will burn up in the atmosphere
Captain: Search "Rods from God", it was experimented with at some point but they abandoned the idea because they're incredibly hard to aim.

OH cool thanks. I would think the guidance system would be the biggest issue.

Also getting them up there is quite expensive because getting weight into space is haha costly...

So I think the conclusion is that hypersonics are cheaper

Ok, forgive my ignorance.
The premise is dropping metallic spears through earth's atmosphere as a weapon of sorts?
Tungsten is vv heavy

Yea, because they pick up a lot of inertia while coming down.

But two problems:
1. Guidance is a bitch.
2. Getting them up there requires 1000x the energy that they end up releasing in the end because of the "you need fuel to move the fuel" problem that makes rocketry suck.

I had no idea this was a theory, wow.
The cost alone as it's fairly expensive to mine & refine first & foremost.
Learn something new every day..

Tungsten isn't that expensive, I mean, you don't build buildings out of it, but it's not precious or anything.

The major costs are the insane amount of rocket power for the ride up, and the crazy guidance system that can steer without burning the flaps off on the ride down...
