The 30 mm trades heavy firepower and rate of fire for low accuracy and muzzle velocity. While this is great against large, slow aircraft like attackers and bombers, this makes the 30 mm Mk 108 a rather poor armament against faster fighters, requiring a lot of lead. The low accuracy is also noticeable in that shells rarely fly straight past a distance. Because of that, the 30 mm should only be fired once within 600 meters of the target.

Description

The MK 108 was a German 30 mm autocannon developed for aircraft mounts. Built as a lighter 30 mm autocannon than the MK 103, the MK 108 presents a faster fire rate at a cost of accuracy and muzzle velocity.

Note: Gunpods containing MK 108 (30 mm) have reduced accuracy compared to those mounted conventionally

Comparison with analogues

Give a comparative description of cannons/machine guns that have firepower equal to this weapon.

Usage in battles

The 30 mm Mk 108 is a devastating weapon to use... if it manages to hit the target.

The 30 mm trades heavy firepower and rate of fire for low accuracy and muzzle velocity. While this is great against large, slow aircraft like attackers and bombers, this makes the 30 mm Mk 108 a rather poor armament against faster fighters, requiring a lot of lead. The low accuracy is also noticeable in that shells rarely fly straight past a distance. Because of that, the 30 mm should only be fired once within 600 m of the target.

Pros and cons

Pros:

  • Filled with a lot of HE filler, giving each impacting shell a serious punch
  • The Night belt consist of Minengeschoß rounds with tracers, making it easier to aim
  • Comes as an upgrade to both motorcannons or as gunpods on the later Bf 109 G series
  • Decent rate of fire for its calibre at 600 RPM
  • Decent ammo capacity
  • Excellent against bombers, heavy fighters and other large targets

Cons:

  • Slow muzzle velocity and poor ballistic coefficient makes it hard to use against targets beyond 500 m
  • Not ideal for dogfighting as it requires a lot of lead angle
  • In a high speed chase, shells may fail to detonate on target, doing little to no damage
  • Absolutely zero effectiveness against armour
  • Heavy recoil which can be dangerous if in a low energy state

The 30 mm shells fired out of the autocannon were relatively slow at around 500 m/s and had a drastic shell drop with range, forcing pilots to close in distance to make an accurate shot . The large 30 mm shells, especially so with the Minengeschoß shells, are able to down a bomber with a few shells. The MK 108 was able to reach a fire rate of 660 rpm, which allowed pilots to make the most out of a burst. The whole weapon was economical to make, being mostly constructed of stamped parts while remaining light and compact for aircraft mounts.

The MK 108 began seeing usage in late autumn 1943 on Bf 109 G fighters and Bf 110 heavy fighters.
