How HMS Diana might have protected a larger Daring-class order

Could naming another 1949 Daring-class destroyer HMS Diana have protected the larger order from cancellation?

Possibly. Diana was a traditional D-class name, and its public association could have made cancelling that ship politically awkward.

Naming a ninth 1949 Daring-class destroyer HMS Diana might have made cancellation politically awkward because the public would connect the name with Diana. The Royal Navy could still point to Diana as a traditional D-class name. That combination would give the ship a contemporary public association and a defensible place in naval tradition. The proposal is speculative, but it shows how an inherited naval name can acquire political weight in a procurement debate.
