Yes. But radar is limited by the horizon in the same way our vision is. It only helps when it is dark or the weather is bad. So, to my understanding, in WWII they could only shoot at the targets in the open sea which were "geometrically" visible. That is not behind the horizon. Unlike in the land artillery or in the interesting case described by Trevor, where they shot from "closed position". I find the example of "navigation" described by Trevor very amazing. One thing I don't understand in this: at what distance you can hear and detect an underwater explosion? Can you indeed hear in England an explosion near Belgian coast? Alex.
