Anti-aircraft limits on a 70,000-ton battleship

How much anti-aircraft armament could a 70,000- to 80,000-ton battleship carry?

More than a smaller battleship, but not without limit: date, crew size, usable superstructure space, and firing arcs still govern the battery.

A 1939 design and a wartime refit lead to different batteries, with perhaps eight heavy AA mounts initially and sixteen after wartime growth. Even on a 70,000- to 80,000-ton ship, crew requirements, superstructure space, firing arcs, and interference between weapons impose practical limits.
