The very few that rely on any form of nuclear power, which is what I'm
guessing you think is involved, are carrying high power radar and have
enough trouble with drag from the large antenna panels

Eh? In a vaccuum?

Define a vacuum. At what height do you think there is one?


Effectively at about 60 miles up..

There's a difference between "effectively" and "none". There's still drag on
low earth orbit stuff.
