How ships of the same navy acknowledge one another

How do ships from the same navy greet one another when they meet in war or peacetime?

They follow established greeting and saluting protocols that determine which ship acknowledges the other first and how.

Ships of the same navy do not simply pass without acknowledgment in peace or war. Established protocols govern the greeting, including which vessel salutes first and how the salute is made. The brief exchange does not enumerate the rank rules, but routine fleet encounters are structured by formal naval etiquette.
