Description

The MG 151 was a 15 mm aircraft-mounted autocannon produced by Waffenfabrik Mauser. The one in-game is the MG 151/20, which is 20 mm version of this autocannon. Its origins stem from the period between WWI and WWII when the German single-engine fighter doctrine at the time mirrored that of the French. It called for a powerful autocannon between the cylinder banks of a V engine, which was known as a moteur-canon by the French. Though the cannon most preferred by the French at the time was the 20 mm Oerlikon FFS cannon, this was too large to fit into German aircraft in the propeller hubs, therefore, Mauser was given the task of developing a cannon which was small enough to fit and did not impact performance too greatly. For a time, the MG FF cannon was used as a stop-gap on German aircraft, unfortunately, its performance was mediocre. Eventually, in 1940, the first MG 151s were put into production. After evaluation of the 15 mm on the Bf-109 E-2, the decision was made to change it to 20 mm cartridges resulting in a re-designated the MG 151/20.

Note: Gunpods containing MG 151/20 cannons have reduced accuracy compared to those mounted conventionally.

Comparison with analogues

Usage in battles

This weapon is very dangerous to air targets due to the minengeschoß shell, which makes the MG 151/20 arguably the best 20 mm cannon against air targets. Unless other ammunition is needed for a specific reason, always choose the ammo belt with most minengeschoß available.

Pros and cons

Pros:

  • Minengeschoß shell (an improved HEI shell) provides a lot of hitting power against aircraft
  • Larger ammo count than the other German 20 mm cannons
  • Higher muzzle velocity than the other German 20 mm cannons
  • Faster firing and less prone to jamming than the Allied Hispano variants

Cons:

  • Still lower muzzle velocity compared to most machine guns
  • Ineffective against armoured ground targets, even with APHE shells
  • Tracer and HEI (minengeschoß) have slightly different trajectories which reiterate knowing your ammunition

History

Converted from the 15 mm-firing MG 151/15 cannon to a 20 mm after combat evaluation proved a larger high-explosive shell to be more effective than a high-velocity shell.

A large shipment of 800 guns was lend-leased to Japan using the Italian submarine Comandante Cappellini, arming 388 Japanese Ki-61-I hei fighter planes.
