I was pretty shocked to find out that wire-guided missiles were(/are?) a thing. This seems easier than that.

Pretty sure they were in the thousand feet range, not multiple kilometers…

(Welp… 3 km range… though to me wire that long seems like it’d be easier than optical cable back in the 70s)

Wire guided is still the primary means of guiding torpedos from submarines, because it gives you an unjammable, un-interceptible, consistent communication interface, and in torpedoes the wire spools out for tens of kilometers.

If you want something really cool, look up old fashioned TV guidance. We built weapons that guided based a TV signal, and edge detection in that signal. In 1958.
