II by the following officers: The timing of the first three appointments was carefully planned, such that a clear order of seniority and a near-equivalence between the services was established for the Generals of the Army promoted at the same time. General Marshall was promoted to General of the Army on December 16, 1944; General MacArthur was promoted on December 18, 1944; General Eisenhower was promoted on December 20, 1944, and General Arnold was promoted on December 21, 1944. He would later be laterally promoted to General of the Air Force on May 7, 1949, after the Air Force was created as a separate service as part of the National Defense Act of 1947. The insignia for a fleet admiral is composed of five silver stars in a pentagonal design. Worn on the service dress blue uniform sleeve was a gold stripe two inches wide surrounding the sleeve two inches from the cuff with four half-inch stripes placed at inch intervals.

Purportedly U.S. Representative Carl Vinson, chairman of the House Armed Services committee and a strong supporter of Halsey, was responsible for blocking subsequent efforts to promote Spruance to fleet admiral (although his promotion continued to be blocked after Vinson retired). Instead, Spruance's achievements were recognized by the unique honor of a Special Act of Congress awarding him full four-star admiral's salary during the remainder of his life. Spruance expressed the following feelings over the issue: The first fleet admiral to leave active duty was Ernest King who retired immediately after the conclusion of World War II. Chester Nimitz and William Halsey both retired two years later while William Leahy was the last fleet admiral to leave active duty in 1949. According to Public Law 78-482, fleet admirals on active duty receive the same pay as a Rear Admiral, Upper Half (two star) plus a $5,000 personal allowance, and upon retirement were to receive 75% of their active duty pay. When Public Law 79-333 made the rank permanent for Leahy, King, Nimitz, and Halsey,
