Large shells must be moved, loaded, and aimed, so their weight affects the practical rate of fire. Early radar did not remove the need to range a target. Even late-war and Korean War fire-control systems used ranging shots, including against stationary shore targets, because information moved through delayed systems with several people in the loop. A larger gun therefore does not automatically deliver proportionate combat advantage.

Heavier shells slow fire control even with radar
Very heavy shells and ammunition handling reduce rate of fire, while early radar still required ranging salvos and human information chains.
