Gun armonization of a Bf 109 E-7 and its MG FF/M cannons.

The MG FF is a German 20 mm autocannon derived from the Swiss Oerlikon FF autocannon. A further development with the acceptance of the Minengeschoß 20 mm shells had the weapon adapted to chamber the round, this was designated the MG FF/M.

History and development

The German drum-fed MG FF cannon was developed in 1936 by Ikaria Werke. Directly related to the Oerlikon FF 20mm, the MG FF was light and easy to mount on existing planes of the time. However, there were several disadvantages with this light cannon. It had a low rate of fire, and pilots complained about how the ammunition ran dry quickly. However, it was quickly adopted by the German Luftwaffe and mounted on early-stage Fw 190s and Bf 109s. The modified MG FF/M used more powerful explosive incendiary shells (known as "Minengeschoße" (literally "mine shells") and was superior to the MG FF. By 1943 the MG FF and its variants were phased out in favor of the faster-firing and more powerful MG 151 autocannon.

In War Thunder

The MG FF and MG FF/M cannons are for example mounted on the He 112 B-2, Bf 110 C-4, Do 217 J, BF-109 E-3, and Fw 190 A-1/A-4/A-5.

  • The MG FFs mounted on the He and Bf are poor. They have bad takedown capabilities, will jam and run out of ammunition too easily.
  • On the other hand, the MG FF/Ms on the FW 190 are fairly powerful. They can destroy about any plane with relative ease, thanks to their HE Minengeschoß rounds. Still, watch your ammo levels.
