Octuple 16-inch turrets against massed missile attacks

How dangerous would a four-turret battleship with octuple 16-inch mountings be if built with 1950s technology?

The turrets are judged mechanically impractical, while opinion differs over how many conventional missile hits the enormous hull could survive.

Four octuple 16-inch turrets would require an enormous beam and a hull large enough to carry their weight. The mountings are dismissed as liable to wreck themselves. Fleet expects missile boats to dispose of the ship, while Alex Clarke disputes how quickly a vessel he estimates at roughly 400,000 tons could be sunk. He expects its mass and armor to absorb numerous conventional missile hits, although he agrees that sufficiently large attacks could overwhelm it. Nuclear warheads provide another way of defeating that scale of protection.
