Fleet admiral (abbreviated FADM) is a five-star flag officer rank in the United States Navy whose rewards uniquely include active duty pay for life. Fleet admiral ranks immediately above admiral and is equivalent to General of the Army and General of the Air Force. It is the same as the discontinued Admiral of the Navy.
Although it is a current and authorized rank, no U.S. Navy officer holds it presently. Only four officers have ever held the rank, all in the World War II era: William D. Leahy, Ernest J. King, Chester W. Nimitz, and William Halsey Jr. Leahy, King, and Nimitz were promoted to the rank in December 1944, followed by Halsey in December 1945. While all four men effectively retired in the late 1940s, the rank of fleet admiral is for life. The last living fleet admiral was Nimitz, who died in 1966.
