And why not just use... a bunker buster?

 

because bunker busters don't win the technological "I have a big dick" award.

 

As an intellectual aside, there would be a calculable shape/mass/velocity at which it became practical to use orbital bombardment weapons. The problem would be that it would probably be a pretty big thing, and only really useful in planet vs planet battles.

Yes it is. Especially when you use it to prove a penny dropped from the empire state building WOULDN'T kill you. It would give you a nasty bruise.

 

now apply this to your uranium rod scenario.

A space elevator would come in handy.

No, because when you go so fast with the uranium you can go hundreds of feet deeper into the ground, thus making bunkers obsolete.

Well, in orbit you are going 17,300 mph, and gravity would make it go a heck of a lot faster. Because typical bunker busters only go 5000. And uranium is more dense so it penetrates farther.

Where are you getting this 17,300 figure from?

At 200 mile altitude you must go 17300 mph to stay in orbit. Less, you go down and speed up. With more speed you go up and slow down.

Read "Do your ears pop in space?" for more.

the point is, you need to get it going at 17,300 mph in the direction of your target, otherwise the number is meaningless. for example the moon is going very fast, but it is not a big threat because it is in orbit.

 

so how are you going to accelerate it so it is going at 17,300 mph towards your target?
