The Huff-Daland Type XV (ICAO: HFFD) is not a documented aircraft model within reputable historical aviation records, including major type lists and museum catalogs. While the designation appears in some modern administrative databases, there is no verifiable evidence in primary or secondary sources—such as the Smithsonian's National Air and Space Museum or Aerofiles—to confirm the existence of a specific airframe designated as the Type XV. Consequently, technical specifications, production numbers, and performance data for this specific model are unknown.
Despite the lack of data on the Type XV, the manufacturer, Huff-Daland Aero Corporation, played a significant role in early American aviation. Founded in 1920 as the Ogdensburg Aeroway Corporation in Ogdensburg, New York, by Thomas Huff and Elliot Daland, the company later moved its headquarters to Bristol, Pennsylvania. The firm specialized in the production of biplanes, which served various roles as trainers, observation aircraft, and light bombers for the U.S. Army and Navy during the 1920s. Many of these designs, such as the Petrel series, formed the basis for the company's later innovations.
One of the company's most enduring legacies was the development of the Huff-Daland Duster, designed between 1923 and 1925. This aircraft was a modification of the military Petrel biplane, equipped with a chemical hopper to facilitate aerial crop dusting. On March 2, 1925, the company incorporated Huff Daland Dusters, Inc., establishing the world's first aerial crop-dusting operation. Based initially in Macon, Georgia, and later Monroe, Louisiana, the company operated across the southern United States, extending its reach to California and Mexico. This operational entity was later acquired by C. E. Woolman and renamed Delta Air Service in 1928, eventually evolving into the modern Delta Air Lines. While the manufacturing arm of Huff-Daland was eventually absorbed into the Keystone Aircraft Corporation and is now defunct, the legacy of its agricultural designs survives; a restored 1925 Huff-Daland Duster is currently displayed in the "America by Air" gallery at the Smithsonian's National Air and Space Museum.
