[1] Designed for the 1926 Schneider Trophy contest held at Hampton Roads, Virginia, the AS.2 was inspired by the American Curtiss D-12 engine.

Unlike the D-12 the engine featured separate steel cylinders and cast aluminium alloy cylinder heads.

[2] The starting point for the Italian engine was the earlier Fiat A.22.

Despite the engine's technical problems it was successful at the Schneider Trophy event, winning on 13 November 1926, with a second AS.2 powered aircraft placing third.
