Spot it by:

French parasol monoplane fighter of the 1920s
Single-engine cantilever or wire-braced parasol wing
Exported to Switzerland and Turkey

A high parasol monoplane with a single strut-braced wing above the fuselage, open cockpit, fixed undercarriage, and a Hispano-Suiza or similar inline engine. The high-parasol configuration with the fuselage visibly below the wing is the key recognition feature.

History

Dewoitine developed the D.9 as one of his early parasol monoplane fighters, demonstrating the configuration's advantages in speed and visibility over contemporary biplanes. The type was produced for export and evaluation; Switzerland and Turkey were among the customers. It was part of the design lineage leading to the highly successful D.500 series a decade later.

Variants

The D.9 was related to the D.1 through D.12 series of Dewoitine parasol fighters, with differences in engine type and airframe details.

Where you'll see it

Operated in small numbers by Switzerland, Turkey, and potentially France; not adopted in large quantities but influential in demonstrating the parasol fighter concept.
