I never got that idea out of his posts. But it occurs to me that the Iowa class battleships were designed to withstand a one ton shell making a direct hit. IIRC one ton is close to the size of a large Soviet era antiship missile and cannon rounds reach up around Mach 2. Again about the speed of a Soviet antiship missile. So if the Iowa class vessel could withstand a one ton shell hitting at Mach 2, then chances are that in terms of kinetic energy transfer a Soviet antiship missile would not be that big a deal.
