The Gabardini G.9 was an Italian single-seat biplane fighter prototype produced by Gabardini in 1923.

G.9

Gabardini designed the G.9 in parallel with its work on its first fighter design, the Gabardini G.8, which had a similar wing cellule. The G.9 was a metal, fabric-covered, single-bay biplane which differed from the unequal-span G.8 by having a shorter-span upper wing and less cabane bracing. It was powered by the 164-kilowatt (220-horsepower) SPA 6a engine - a more powerful engine than that of any G.8 variant, driving a two-bladed propeller.

The Regia Aeronautica (Italian Royal Air Force) did not place a production order for the G.9

G.9bis

Gabardini re-engined the G.9 with the 224-kilowatt (300-horsepower) Hispano-Suiza HS 42, replaced its frontal radiator with two radiators mounted on the sides of the fuselage above the leading edge of the wing, raised its cockpit, increased the gap between its fuselage and upper wing, and increased the height of its undercarriage to create the G.9bis. After Ing Filippo Zappata (1894-1994) joined Gabardini in 1923, he further modified the G.9bis; among various changes he made were an improved engine cowling intended to reduce aerodynamic drag and the mounting of a large propeller spinner.

In October 1923, Victor Emmanuel III (1869-1947), King of Italy (1900-1946), visited Cameri airfield, where he observed a demonstration of the G.9bis. Flown by Lodovico Zanibelli, the G.9bis achieved a maximum speed of 250 kilometers per hour (155 miles per hour) during the demonstration. However, the Regia Aeronautica was no more interested in the G.9bis version of the aircraft than it had been in the G.9 version, and no production order resulted.
