What is necessary for an officer to be appointed to the rank of Fleet Admiral?

The appointment to the rank of Fleet Admiral requires presidential approval, as this position is a special rank conferred by the President of the United States. As established by legislation, the rank is awarded during wartime and is not merely a reflection of time served or combat experience. It is a unique position intended to provide highly experienced naval leadership during exceptional circumstances, such as a significant conflict.

Other factors, while they may contribute to an officer's qualifications or overall career, do not have the same direct influence on the appointment to this specific rank. For example, although combat experience can enhance an officer's qualifications, it is not a formal requirement for the rank of Fleet Admiral. Furthermore, time served in the Navy reflects an officer's career but does not guarantee rank advancement without the necessary approvals. Similarly, commissioning from a military academy is part of the general path to becoming an officer but does not specifically relate to the appointment to Fleet Admiral.
