The SIA.7B was accepted for the Italian Air Force in November 1917 and entered mass production. There were however revealed its shortcomings, like low wing structure durability and poor view.
[ Next variant SIA.7B2, developed in December 1917, had strengthened wings, slightly raised cockpits and stronger engine. Another variant, built in February 1918, was the SIA 9 with stronger 700 hp engine. There were built 501 SIA.7B, 71 SIA.7B2 and 62 SIA.9B.][SIA.7(9) at Ugolok Neba]
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.
