Yes, hence my initial doubt that SS4s were operational. When I looked at this properly about 5 years ago for my Masters I'm certain the outcome was that no SS4s or SS5s were in Cuba, just the FROGs and (unknown at the time) tac nukes. I still believe that to be the case, but can't find a good reference to hang on to.
Did you even read what I said? I'm saying that was completely wrong.
Hell, if there were no SS-4s or -5s in Cuba, then what pray tell did that U-2 photograph on October 14th?
