Design
Project of Italian kite balloon type was assigned to Major Luigi Avorio, Chief of the Aeronautical Division of the Italian Army, and Dr. Eugenio Prassone, director of the Stabilimento costruzioni aeronautiche militari aircraft factory in Rome. The first prototype was finished in 1915, series production followed soon after. By its design the type followed the shapes of French Caquot kite balloon being more spherical, although it was still able to generate some aerodynamic lift and like the Caquot, had three fins for stability balance.Operational history
At the beginning of the war Avorio-Prassones were used exclusively by the Italian army, for example as anti-aircraft defence tools in Venice and other Italian cities. Some units were also produced in the United Kingdom under the license and at the end of the war used as a barrage balloons in London area.On 12 August 1918 Avoria and Prassone received an U. S. patent for their balloon unit. In the same month the U. S. Navy brought two of the units and put them under the tests in the military balloon school in Fort Omaha, Nebraska. At least thee other units were manufactured in Connecticut Aircraft Comp. factory in 1920 for the U. S. Navy. In 1930 U. S. military forces owned eight of Avorio-Prassone units.
