The Fokker D.XXI is a fairly pleasurable aircraft to play. Its manoeuvrability is quite good, being able to outturn a lot of aircraft of this BR. Also, its climb rate is great for its BR. However, keep in mind that it it rather slow, and might not be able to keep up with other fighters.

The Fokker D.XXI is armed with:

  • 2 x 20 mm Oerlikon FF cannons, wing-mounted (60 rpg = 120 total)
  • 2 x 7.7 mm FN-Browning M.36 No.3 machine guns, nose-mounted (500 rpg = 1,000 total)

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons


  • Powerful armament consisting of 2 x 20 mms and 2 x 7.7 mms, can easily start fires and shred biplanes
  • Above average climb rate for its BR
  • Only one fuel tank, so fires usually would not be started if the aircraft was tailed
  • Great turn time (16 seconds in RB)
  • Engine takes a while to overheat on WEP
  • Does not rip or even compress at little over 600 km/h, allowing it to safely dive on its opponents
  • Short takeoff run
  • As a premium aircraft, has better SL and RP rewards than regular aircraft
  • Fixed landing gear makes landings easier and more simplified


  • Rather slow for its BR
  • Only has landing flaps
  • 20 mm cannons technically only have 60 rounds (60 rounds per gun, but they fire at the same time)
  • Cannons have a rather slow rate of fire
  • Cannons easily overheat after a short time of continuous firing
  • No armour



Development of what would become the Fokker D.XXI began in late 1934 with engineers at the Fokker company seeking to design a modern fighter aircraft, incorporating some of the latest aviation technologies. In 1935, the Dutch Air Force ordered the construction of a prototype which would be evaluated by its East Indies branch, as a result of the aircraft being seen as suitable for defending Dutch overseas assets.

Although its maiden flight in 1936 showed enough promise, the fate of the Fokker D.XXI was “hanging in the air” for a time due to a change in doctrine within the Dutch Air Force. As a result, Fokker began looking into promoting the aircraft on the export market, hoping to find foreign customers.

Fortunately, Fokker received interest from both Denmark and Finland to purchase a number of aircraft as well as rights to production. At the same time, domestic interest was also revived, resulting in the start of production in 1937.

Despite being a Dutch design, the Fokker D.XXI was predominantly produced and employed by Finland. Having built and operated around ⅔ of all D.XXIs, the Finnish Fokkers distinguished themselves during the Winter and Continuation War, although with less success in the latter due to their dated design. The Dutch Fokkers also put up a stiff resistance to the invading German forces in May 1940, shooting down a number of enemy aircraft, including several superior Messerschmitt Bf 109s. In the end, approximately 150 D.XXIs were built, serving up until 1949 with Finnish forces.
