Several officers aboard a French warship may hold a title translated as captain, but their full grades distinguish experience and the scale of unit they are qualified to command. The hierarchy grew from sailing-era vessel categories. Corvette, frigate, and ship-of-the-line grades therefore mark progressively different command expectations. That history gives the apparently repetitive system a practical logic and preserves command identity if a more junior captain succeeds a casualty.
