The MG FF is a German 20mm autocannon used widely during the early stages of World War II. It was designed to be mounted in the wings of fighter planes, such as the Messerschmitt Bf 109E, being one of the first 20mm guns to be small and light enough for this purpose. The MG FF used a blowback mechanism and fired 20x80mm rounds from a drum magazine, which was limited to 60 or 90 shots. It had a rate of fire of about 520 rounds per minute and a muzzle velocity of 600 m/s. This autocannon was effective against lightly armoured targets but had limited range, accuracy and magazine size, also prone to jamming and overheating. The MG FF was introduced in 1937 and saw combat in the Spanish Civil War and the early stages of World War II, later being replaced by the more powerful and reliable MG 151/20/20 cannon, which used a different 20x82mm round.

Auto
This weapon is fully automatic, either inherently so or by the presence of a selective-fire mechanism.
EFFECT:
This weapon can fire more than one shot each time it is used. Each subsequent shot has a progressive penalty.
Automatic weapons are considered STABLE when they're mounted on a vehicle, tripod or turret. This is different from the Stabilised SA.
- Point Blank Range - No penalty.
- Close Range (≤10m / 2sq) -> -1
- Short Range (≤50m / 5sq) -> -2 (STABLE: -1)
- Average Range (≤200m / 10sq) -> -3 (STABLE: -1)
- Medium Range (≤500m / 20sq) -> -5 (STABLE: -1)
- Long Range (≤1000m / 50sq) -> -5 (STABLE: -3)
~ Beyond this point, automatic fire is unfeasible without a STABLE firing platform. ~ - Very Long Range (≤2000m) -> (STABLE: -3)
- Extreme Range (>2000m) -> (STABLE: -5)
