>The US has had radio programmed artillery shells

These are just proximity fuses. I can find no reference to actual communication with in-flight artillery shells. Furthermore Nuclear Artillery shells were armed when loaded. They were one of the few systems outside of the two-man rule. As a single inferior officer would arm the shell when loading it.

I didn't mean radio programmed in flight just before they were loaded proximity fuses could be armed and configured via rf.
