The SIAI S.17 was an Italian racing flying boat built by SIAI for the 1920 Schneider Trophy race.

Design and development

Although earlier SIAI aircraft had been employed as racers, the single-seat S.17 was SIAI's first specialized racing aircraft designed as such. Its 231 kW (310 hp) Ansaldo San Giorgio 4E-14 engine gave it a top speed of 290.9 km/h (157.1 kn; 180.8 mph).^[1][2]

Operational history

The S.17 participated in the 1920 Schneider Trophy races at Monaco, but crashed during the final take-off and did not finish.^[3]
