I have my doubts. You would have to stop it from orbiting first (8km/s). What kind of rocket would be needed to get 8km/s deceleration of 12 tons on LEO? And it would only gain 10km/s. Why not go directly from the ground then?

It doesn't even take 1km/s to deorbit.

Yeah but you'd want your orbital kinetic weapon to pass through as little atmosphere as possible to minimize aerodynamic breaking and to reduce the accuracy problems inherent in those aerodynamic effects. The steeper the reentry, the better, which means a greater delta-v requirement.

Maybe highly elliptical orbits?
