Yes, it makes sense if such old stuff was experimented with in secret but then not used for decades. But since we are entertaining conspiracies, what if US also is using this weapon, then they won't want to admit it and give clues on how to prove it was used. My opinion(very uninformed) is that it is more probable that if a device is involved then it is some kind of spying/scanning tool and not a weapon.
