it also provided for full pay and allowances once those officers retired. As with a general of the army, a fleet admiral was entitled to an office maintained by the Navy along with an aide (of the rank of Captain), a secretary, and an orderly. Three of the four fleet admirals died in the late 1950s and, by 1960, Chester Nimitz was the sole surviving U.S. Navy fleet admiral. He held a ceremonial post as Navy adviser to the Western Sea Frontier with his quarters based in San Francisco. Nimitz died in 1966 with no further fleet admirals appointed since. Modern usage No officers have been appointed to the rank of fleet admiral since William Halsey. The rank of fleet admiral is still maintained as a rank of the U.S. Navy, and could again be bestowed, pending approval of the United States Senate. However, the President, with consent from the Senate, may award a fifth star at any time they see fit. In the 1990s, there were proposals in Department of Defense academic circles to bestow a five-star rank on the office of the Chairman of the Joint Chiefs of Staff. As recently as the late 2000s, some commentators proposed that the military leader in the Global War on Terrorism be promoted to a five-star rank. Ranks senior to fleet admiral The Navy does not have an established rank senior to fleet admiral. The only officially recognized United States military rank senior to fleet admiral is General of the Armies when Congress passed in 1976, promoting George Washington to that rank and making him senior to all other grades of the Army, past or present.
