WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

A low-wing monoplane with a noticeably fixed and spatted undercarriage, a radial engine, and a relatively slender fuselage. The fixed gear immediately distinguishes it from near-contemporaries like the Hurricane or Spitfire. The tapered wings and rounded wingtips are characteristic.

History

Designed by Fokker for the Netherlands East Indies Army Air Service, the D.XXI also entered service with the Royal Netherlands Air Force and was licence-built in Finland. It saw intense combat during the Finnish Winter War (1939–40) against the Soviet Air Force, and Dutch D.XXIs fought briefly against the Luftwaffe during the May 1940 invasion. Despite its fixed undercarriage, its manoeuvrability allowed Finnish pilots to score significant victories.

Variants

The Finnish-built version used a Bristol Mercury engine rather than the original Mercury VIII; minor armament and equipment differences also existed.

Where you'll see it

Operated by the Royal Netherlands Air Force and the Finnish Air Force; Finnish aircraft remained in service into the Continuation War (1941–44), though increasingly relegated to secondary duties.
