Would the replacement guns create a topweight problem?

How would the replacement armament affect the ships' topweight?

The proposed lighter installations are expected to fit the weight allowance released by removing the old six-inch guns.

The comparison includes the gun mount and associated equipment. The rough figures put a complete old six-inch installation around nine to ten tons and the proposed twin installation around four tons. On those figures, replacing the original battery should provide room for the new gun arrangement. This is the weight estimate used for the proposed conversion.
