Operational history

The SIA.7 family aircraft were used for reconnaissance and bombing raids on Austro-Italian front. The SIA.7B2 entered service in March 1918. The SIA.9 managed to take part in World War I service as well. Because of unsatisfactory durability, from July 1918 SIA.7B and 7В2 were moved to training units. In 1917, the Italian government sent a pair of SIA 7B-1 aircraft to the United States for evaluation under a plan to mass-produce established European designs. The 7B-1 was not put into production in the US but 19 were bought in Italy for use by A.E.F. units sent there.
