U.S. Air Force Flag
The U.S. Air Force flag consists of an ultramarine blue, which is the air force’s branch color. The flag is 4 feet 4 inches wide by 5 feet 6 inches in length. The indoor version of the flag has a 2 ½ inch yellow/gold border around the outer edge. The coat of arms of the Department of the Air Force is in the center of the flag.
The flag is always carried with streamers commemorating the air force’s battles and campaigns, starting with the Mexican Expedition in 1916-1917. The air force was a part of the army until 1947 and its battle streamers from that period are also flown with the US Army flag.
