How a successful naval weapon becomes fleet standard

How much persuasion was needed to spread a successful weapon such as proximity-fuzed anti-aircraft shells across a fleet?

A senior officer still had to present evidence, but a responsive Admiralty could standardize a proven weapon far faster than an obstructive bureau.

Admiral Willis Lee's rank gave his recommendation unusual weight in the US Navy. A British officer could report successful evidence to the Admiralty and receive a fleet-standard decision. Junior innovators would face a harder route through hierarchy in either service. Institutional behavior determines whether working technology reaches ships in time.
