And it doesn't have to be anything like that. Have none of you heard of "Thor"?
Thor is a theoretical space-based weapon which just sits in orbit once it is deployed. It consists of 10m iron rods equiped with attitude rockets for aiming purposes.
At need, Thor can be brought down on any building, destroying it only minutes after the decision is made. There is no real defense against this except a VERY DEEP bunker, maybe. Given the terminal velocity of the dumb iron, the force involved would be like a small nuke IIRC, but w/o radiation. It'd look like a nuke, too. And it should be fairly cheap.
Just about any kind of mass would work for this: rock, iron, frozen water, asteroid material, whatever.
