Re: Tungsten Rods / Orbital Weapon
Jerry Pournelle thought up the concept, but he'd most certainly read the "Doc".
The ones mooted for use by the USAF were 11.5 ton TNT equivalent, but would have a mass of 8 tons. Impact speed was Mach 10. A conventional bomb could do as much damage for less cost as the article points out.
A city rather than bunker buster would have to mass many tens of thousands if not millions of tons -- as the Chelyabinsk meteor demonstrated. It would take project Orion to heft that much stuff around so why no just use the nukes themselves.
