What a modern 16-inch naval gun might become

What would a 16-inch gun look like if naval artillery development had continued?

The gun itself might look familiar, but its breech and loading system would probably be automated.

Heavy naval ammunition already depended on extensive machinery because shells and charges were too large for manual handling alone. A modern system would extend that mechanization into a true autoloader. The charges would probably be rigid or cased so machinery could select the correct quantity for the computed range. Breech operation, ammunition selection, loading angle, and firing would become one integrated sequence rather than separate manual evolutions.
