Was the first lieutenant the Royal Navy equivalent of an executive officer from 1850 to 1950?
Short answerOften on smaller ships, but titles and ranks varied with ship type and size.
NotesNo single title fits every Royal Navy ship across a century. A destroyer's first lieutenant could perform the function commonly called executive officer. On a battleship, the officer might hold the rank of commander or another senior appointment. Sources may call the same general role first officer, executive officer, first lieutenant, or simply the commander.
