Why navies missed the guns-versus-missiles warning from Vietnam

Why did navies not draw the same guns-versus-missiles lesson from US air combat in Vietnam?

Their missiles were much larger, so planners assumed naval weapons were better and did not treat the fighter-combat warning as directly applicable.

Navies did not automatically carry the US air-combat lesson about guns and missiles into their own systems. Naval missiles were much larger, which encouraged the assumption that they were correspondingly better and that the analogy did not apply. That confidence filtered an outside warning through expectations about a different weapon scale. The compact exchange concerns institutional learning rather than a claim that every missile system shared the same fault.
