How navies carried lessons from one war into the next

How well did navies study earlier wars before the world wars, and did new technology make those lessons obsolete?

They studied them seriously, and lessons such as the Royal Navy's focus on night fighting still paid off despite technological change.

Technological change did not make earlier naval wars irrelevant. Major navies examined their previous operations in depth and carried selected lessons into new doctrine. The Royal Navy's emphasis on night fighting before and during the Second World War is one example of that institutional learning. New technology changed how the lesson was applied, but did not remove the value of studying the earlier experience.
