Whether postwar super-battleships would lose guns

Why would the postwar Royal Navy remove guns from 70,000-ton super-battleships?

It might not; the decision would turn on strategic threats, replacement weapons, and the gap between wartime and peacetime crew strength.

A surviving 70,000-ton battleship might retain its battery if wartime performance preserved the type's capital-ship status or if Soviet construction demanded high readiness. It might instead shed guns when new systems offered more value or peacetime personnel ceilings made the turrets too expensive to crew, maintain, and supply.
