The two sets of sisters were exceptional capital assets rather than ordinary members of a large modern fleet. When radar or improved sensors became available, the Royal Navy directed the technology toward these four ships. That priority could keep a scarce hull tactically relevant even when it had not received the same structural reconstruction as its sister. Fleet scarcity influences modernization choices as well as deployment.

Renown, Repulse, Nelson, and Rodney received priority for radar and sensor improvements because Britain had so few comparable capital assets.
