The SAI.7 racing aircraft first flew in 1939. Wartime advanced trainer and light fighter variants were unsuccessful, but 145 examples were built of the postwar S.7 trainer. Only two protypes were produced of the more powerful Super S.7, or Supersette. Before becoming the first Super S.7, this airframe flew as the S.7 Freccia, fitted with a 45 degrees swept wing and nosewheel gear to help design the Ambrosini Sagittario jet.

Built for an air race in 1939, the SAI.7 evolved into the SAI.7T and S.7 trainer and tourist aircraft during and after WW2. The final version, this Super S.7 armed trainer, never got further than two prototypes.
