> GPS jamming protects Russia's command and control structures from American intermediate range cruise missiles that can be launched from Mk41 launchers in Romania and Poland

I don't think Mk41 are operating in these two countries.[0] They do have Aegis Ashore [1] though which is an anti-ballistic defense system. AA uses SM-3 missiles that in theory could reach Moscow though.
