Heavy-cruiser calibre must preserve rate of fire

If 9.2-inch guns suited a heavy cruiser in a 12-inch-battleship world, were Alaskas under-gunned in a 16-inch world?

Larger guns reduce the rapid fire a cruiser needs against other cruisers. Alaska could defeat heavy cruisers and escort carriers, but that did not make it the best long-term solution for every role.

Heavier cruiser guns can be plausible in the right strategic setting, but rate of fire falls as calibre rises. The Dutch considered a 9.4-inch gun for a 1930s force built around paired cruisers and battlecruisers, a choice that might have encouraged other navies to explore similar weapons. The Alaska class could defeat heavy cruisers and still serve as a carrier escort, though Iowa-class battleships performed the escort role more effectively. Alaska's original anti-cruiser mission made sense when conceived, but wartime change reduced the need by the time the ships entered service. Gun size has to match the enemy a cruiser must fight and the rate of fire that fight demands. The availability of Iowa-class hulls also changes the case for a specialized Alaska as a carrier escort.
