What rank corresponds to the highest Navy pay grade, O-11?

The rank that corresponds to the highest Navy pay grade, O-11, is the Fleet Admiral. This position is a four-star rank that is reserved for wartime use and is the pinnacle of naval ranks, reflecting both the individual’s extensive experience and the highest level of command responsibility within the Navy.

The Fleet Admiral rank was established during World War II, with notable holders including William D. Leahy, Ernest King, Chester W. Nimitz, and William Halsey Jr. Because it is only used in times of war and is not a permanent rank, it underscores the exceptional level of leadership and service provided by those who achieve this status.

Other ranks such as Admiral, Commander, and Rear Admiral do not reach the same pay grade or authority as Fleet Admiral. Admiral, for instance, is an O-10 rank, while both Commander and Rear Admiral have lower pay grades and command responsibilities.
