Entering war can halt promising programmes just before they become operationally useful. As First Lord of the Admiralty, Winston Churchill paused capital-ship, carrier, cruiser, and other naval development to concentrate resources on the immediate fight. That policy suited the First World War context better than the differently structured Navy of 1939. Its procurement leadership had moved away from Jackie Fisher's approach and had already ordered many smaller ships, so interrupting the transition also delayed capabilities such as Torpex that were close to service.

Churchill's decision to pause construction and development repeated a First World War response even though the 1939 Royal Navy had invested more heavily in small ships and methodical procurement.
