Postwar large naval guns refined more than they reinvented

How far have large naval guns developed from their Second World War counterparts?

Less than is often assumed; much of the change is repackaging, rebranding, and refinement rather than new core gun design.

Fundamental large-gun design changed much less after the Second World War than the elapsed decades might imply. Later systems often repackage earlier principles and refine features around the edges. A modern installation can therefore differ substantially in presentation and supporting systems without introducing a genuinely new ballistic or mechanical concept.
