Postwar retirement saved money and opened promotion paths, but it also removed experienced officers. The Royal Navy used fleet exercises both to preserve institutional knowledge and to judge the next generation in peacetime.

Admiralty leaders repeatedly had to explain to politicians and Treasury officials why those visible costs were the price of combat readiness rather than proof of careless waste.
