The Mauser '''20 mm MG 151/20''' is a German 20 mm aircraft cannon converted from the 15 mm [[MG 151/15 (15 mm)|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.

The key features of the MG 151 is the special Minengeschoß (lit. "mine shell") high-explosive ammunition. This Minengeschoß round was specifically made with a thin tungsten casing to contain more explosive filler (usually 50% more than regular HE shell) and thus were extremely effective against enemy aircraft.

The 20 mm MG 151 is very dangerous against 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.

With "air targets" belt, it usually take a short burst of 20 - 30 rounds to take down an average fighter, 30 - 50 rounds for a heavy fighter or a ground attack aircraft, and 100 - 150 rounds for a heavy bomber. Due to the gun's fast rate of fire, however, it is quite easy to empty all of the ammo before you managed to finish the targets without proper aiming, especially without the help of gun pods. Thus, the MG 151 will often requires trigger discipline for better results, with an ace being achieveable in a single sortie with a proper ammo conservation.
 
−
 
 
−
However, despite the MG 151's stellar characteristics, the gun is also infamous due to its poor stock performances. Owing to the fact that only 1/4 of its stock belt contains the "Minengeschoß" round, while the other rounds were a near-useless incendiary shell with a performance akin to that of a practice shell found on the Hispano autocannons, as well as poor APHE rounds that often over-penetrates the enemy airframe and thus were unable not detonate. Due to this, it is best to treat the stock MG 151 like an oversized heavy machine gun. Firing a long burst to get more chance of hitting the enemy with Minengeschoß rounds until the upgraded belts are available.

The [[MG 151 (15 mm)|MG 151]] was originally developed for a 15 mm cartridge which was small enough to fit between the cylinder banks of their V-12 aircraft engines and offered a higher velocity compared to the 20 mm cannons of their Allied opponents. However, in 1941, Germany recognized that, in air combat, explosive power was more important than high velocity. As a result, in 1941, the MG-151 was re-chambered to fire a 20 mm shell based on the cartridge used by the [[MG FF (20 mm)|MG FF]], but necked up and with a longer case body meaning that the conversion mostly involved changing the barrel. The MG 151 was introduced on the [[Bf 109 F-4]], would remain one of the main fighter cannons for Germany during World War II, and would be popularly exported to other nations in the Axis, such as mounting on the Japanese [[Ki-61-I hei]], Italian [[Re.2005 serie 0]], and Romanian [[IAR-81C]] fighters. However, Germany's attempt to make an explosive shell for the MG 151 became its downfall. The Minengeschoß (Mine Shell) rounds were ineffective against the Allied heavy bombers taking about 15-20 hits to down one while a 30 mm cannon such as the [[MK 103 (30 mm)|MK 103]] needed only 3 or 4 hits to down. As a result, the MK 103 and its shorter-barrelled cousin the [[MK 108 (30 mm)|MK 108]] began to replace the MG 151 as the Luftwaffe's (German Air Force) main cannon near the end of the war and it was adapted by the Volkssturm (German national militia) for use as an anti-aircraft weapon along with being used to upgrade the 15 mm armed [[Sd.Kfz.251/21]]. After the war, the MG 151 was used by the French Armée de l'Air (Air Force) and Aviation légère de l'armée de Terre (Land Army Light Aviation). In both fixed and flexible configurations, the MG 151 was used by the French in multiple aircraft including helicopters such as their H-21C Workhorse and [[H-34 (France)|H-34]] helicopters used in Algeria. The flexible variants were modified with insulating sleeves to protect the user's hands. The MG 151 was also used in the Portuguese and Rhodesian versions of the [[SA 316B Alouette III]], and a variant of the cannon called the Vektor GA-1 was built by Denel in South Africa.

General info

Tell us about the tactical and technical characteristics of the cannon or machine gun.

Available shells

Describe the shells that are available for the cannon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).

Comparison with analogues

Give a comparative description of cannons/machine guns, that have firepower equal to these type of weapons.

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 20mm cannon against air targets. always choose the ammo belt with most Minengeschoß available.

Pros and cons

Pros:

  • Minengeschoß shell (an improved HEI shell) provides lots of hitting power against aircraft
  • Larger ammo count than the other German 20mm cannon
  • Higher muzzle velocity than the other German 20mm cannon

Cons:

  • Still lower muzzle velocity compare to most machine gun
  • Ineffective against armored ground target
  • Tracer and HEI(Minengeschoß) has slightly different trajectory which is sometimes confusing

History

Examine the history of the creation and combat usage of this weapon. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article.

Media

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
