Fleet admiral
Fleet admiral is a five-star US Navy rank created in the Second World War. The Department of Defense lists it as reserved for wartime only, and nobody holds it today.
How to read it
Congress created the grade on 14 December 1944, according to the Naval History and Heritage Command, and four officers held it: Ernest J. King, William D. Leahy and Chester W. Nimitz from December 1944, and William H. Halsey from December 1945. Each served in the grade until he died. The law included a sunset clause that ended the president’s power to appoint five-star officers six months after the formal end of hostilities, and none have been appointed since. The notes to the law that lists the Navy’s grades say fleet admiral is left out because the law authorising appointments to it was limited. The Department of Defense’s insignia chart shows it as O-11, above Admiral (O-10).

Ranks and insignia as the US Navy’s own uniform regulations and pages set them out. Pay grades are the Department of Defense’s.
Stripes on the sleeve
The Navy’s uniform regulations still describe the fleet admiral’s sleeve insignia: one 5 cm (2 in) gold stripe with four 13 mm (½ in) stripes above it, one more than an admiral.
The Army’s five-star rank
The same 1944 law created five-star ranks for Navy and Army officers. The Army’s is general of the Army, which the Department of Defense also lists as reserved for wartime.
