The Royal Navy was synthesizing lessons from the 1920s while recognizing that aviation, submarines, communications, and night operations had changed the problem inherited from the First World War. Exercises produced more questions and improvement points than grounds for confidence, even in areas such as night fighting where the service compared well with other navies. That willingness to expose uncertainty mattered because the fleet still had a decade to refine doctrine before the Second World War. The service benchmarked itself against whichever navy or formation seemed most capable and demanded further progress from officers and formations instead of treating competence as enough.
