* Nimitz never held the rank of [[lieutenant junior grade]], as he was appointed a full lieutenant after three years of service as an ensign. For administrative reasons, Nimitz's naval record states that he was promoted to the rank of lieutenant junior grade and lieutenant on the same day.
* Nimitz was promoted directly from captain to rear admiral. During Nimitz's service, there was only one rank of [[rear admiral (United States)|rear admiral]], without the later distinction between upper and lower half, nor did the rank of commodore exist when Nimitz was at that stage of his career.
* By presidential appointment, he skipped the rank of [[vice admiral (United States)|vice admiral]] and became an admiral in December 1941.
* Nimitz's rank of [[Fleet admiral (United States)|fleet admiral]] was made permanent in the [[United States Navy]] on 13 May 1946, a lifetime appointment.<ref>Archival service record of Chester Nimitz, "Awards and dates of rank", [[National Personnel Records Center]], released 2008</ref>
