Fokker D.XXI

The Fokker D.XXI fighter was designed in 1935 for use by the Royal Netherlands East Indies Army Air Force. As such, it was designed as a cheap and small, but rugged aircraft, which had respectable performance for its time. Entering operational use in the early years of World War II, it provided yeoman service for both the Luchtvaartafdeling (Dutch Army Aviation Group) and the Finnish Air Force, and a few were built by the Carmoli factory before the factory fell into Nationalist hands during the Spanish Civil War.

Fokker D.XXI in The War That Came Early
The Fokker was the only fighter of the Dutch to give the Luftwaffe a challenge during the German invasion of the Netherlands in the final weeks of 1938. Hopelessly out classed, the fighters were thrown in because it was all the Dutch had.
