Regarding the tungsten rods from god (RFG), your specified 20x1 round would be about 24,000lbs. That means that you could put two shots up per Falcon 9 launch with hardly anything left to spare for anything non-tungsten (guidance, fuel). Just using launch capacity we can see that unless Starlink, and basically all of SpaceX, is a giant maskirovka, then the US hasn't fielded any such weapon in meaningful amounts.[0] The RFG sats would need to be LEO or some polar orbit to have some chance of not immediately being outed (a bigass GEO/GSO parked over Moscow would draw notice). Additionally LEO sats deorbit after a human-relevant-while so your rods from god would need to have and EOL plan or some way to do on orbit maintenance because if they deorbit from either EOL or guidance failure then they wouldn't burn up on the way down and could be catastrophic. Then let's also consider the risk that such a weapon draws an ASAT attack either wittingly or unwittingly from Russia or China. Now we have a cloud of tungsten flechettes in orbit. As much as I'd love to see some awesome space weapons, at the moment there's no way they're fielded and a big reason for that is that they'd basically be more of a liability than a capability at the moment. Also the ballistic missiles in question don't use (only) GPS for guidance, they also use inertial and celestial navigation which is pretty spoof-proof when you're aiming at a city. [0] also since we can track and even see starlink sats, we can be confident that none of those flights were used for RFGs, so that further reduces the hypothetical upper bound of the rounds in orbit.
