Fleet Admiral of the United States Navy (FADM) is a five-star flag officer and is the highest possible rank in the United States Navy. Fleet Admiral ranks immediately above an
Admiral and is equivalent to a General of the Army and a General of the Air Force; there is no established equivalent five-star rank in the other four uniformed services. The Fleet Admiral rank is reserved for war-time use only and the grade is not currently in use by the Navy.
The insignia for Fleet Admiral comprises five stars in a pentagon design with a thick rank stripe, below four smaller stripes, on the service dress blue uniform.
A close contender for the rank of Fleet Admiral was Raymond A. Spruance; however, U.S. Representative Carl Vinson, a strong supporter of William F. Halsey, was reported to have on several occasions blocked the final promotion of Spruance to Fleet Admiral.[citation needed]
Since the close of the Second World War, there have been no additional Fleet Admirals appointed in the United States Navy. However, the rank still remains listed on official U.S. rank insignia precedence charts and could be reestablished at the discretion of the United States Congress. Some Navy documents, especially those teaching new sailors the rank structure, have stated that the rank officially expired upon the death of Fleet Admiral Nimitz in 1966. Its reenactment will require another act of Congress.
U.S. Naval tradition holds that the rank Admiral of the Navy is considered senior to that of Fleet Admiral. The only person to ever hold the rank of Admiral of the Navy was George Dewey. Dewey was awarded the rank after his service in the Spanish-American War.
All five star officers are, technically, unable to retire from active duty. This is more of a convention of honor than a practical matter, as five star officers continue to be paid full salary for life, unless (as Dwight D. Eisenhower did upon his election to the Presidency) they formally resign their commission. President Eisenhower's commission was retroactively reinstated back to 1944 by an Executive Order of President John F. Kennedy after President Eisenhower left office.
