The Bureau of Aeronautics (BuAer) was the U.S. Navy's material-support organization for naval aviation from 1921 to 1959. The bureau had "cognizance" (i.e., responsibility) for the design, procurement, and support of naval aircraft and related systems. Aerial weapons, however, were under the cognizance of the Navy's Bureau of Ordnance (BuOrd). Origins The USN's first attempt for naval aviation began in 1908 when it conducted observations of the Wright Brothers aircraft at Fort Myer, Virginia. First tests and Naval Aviation Corps The first test of an aircraft from naval vessel was in 1910 when a Curtiss Model D flown by Eugene Burton Ely took off from the USS Birmingham (CL-2) and again on USS Pennsylvania (ACR-4) in early 1911. These test was enough for the USN to establish naval aviation units in the summer of 1911. The purchase of the first naval aircraft in May 1911 and passage of naval appropriations act in August 1916 lead to the establishment of the Naval Reserve Flying Corps, which would train and deploy air corps for World War I. Formal Organization of Naval Aviation Congress established BuAer in 1921 in order to create a single organizational home for naval aviation. Prior to 1921, cognizance for aviation had been divided among various Navy bureaus and other organizations. The first Chief of BuAer was Rear Admiral William A. Moffett (1869–1933), a Medal of Honor recipient and battleship commander who had long supported the development of naval aviation. He served as bureau chief from 1921 until his death in 1933, in the crash of the airship USS Akron (ZRS-4). Working closely with RADM Moffett, CAPT Henry C. Mustin (1874–1923) served as BuAer's first Assistant Chief helping lead naval aviation to the forefront of American military strength. A talented administrator, Moffett ensured the continued independence of naval aviation during the 1920s, when Army Brig. Gen. Billy Mitchell and others sought to merge all U.S. military aviation into a single, independent air force. Upon Moffett's death, he was succeeded as Chief of the Bureau by Rear Admiral Ernest J. King, a future Fleet Admiral and Chief of Naval Operations during World War II. Other important bureau chiefs included Rear Admiral John S. McCain Sr., the grandfather of U.S. Senator John S. McCain III (R-Ariz.). During the 1930s, BuAer presided over rapid technological change in naval aircraft. The bureau's policy was to limit its own production, in order to support
