The '''20 mm Type 99 Model 1''' is a Japanese aircraft cannon, one of the most commonly used by the IJN. It can be found on the defensive turrets of quite a few bombers, as well as many early fighters. The cannon is on par with those of other nations, and it has a decent damage potential while having a low rate of fire.

While all Type 99s are labeled as simply ''Type 99 Model 1'' (and ''Type 99 Model 2''), there are variants between them that mainly only reflect in ammo count:
 
−
* '''Type 99 Model 1, Mark 1''' - (30 - 45 - 60 rds Drum) Initial gun with 60 rds drum mag feeding from the top.
 
−
* '''Type 99 Model 1, Mark 2''' - (30 - 45 - 60 rds Drum) Inverted feeding so drum mags could be inserted from beneath, allowing for gunner line-of-sight.
 
−
* '''Type 99 Model 1, Mark 3''' - (100 rds Drum) Increased drum size.
 
−
* '''Type 99 Model 1, Mark 4''' - (125 - 250 Belt) Switched out to a belt-fed system making the gun heavier.

The Type 99 cannons are a bit tricky to use compared to German, Russian, or American counterparts. They have an extremely low rate of fire, of 450 rounds per minute, and poor velocity as well. Furthermore, the stock belts for these cannons are incredibly poor. However, these downsides come with advantages. These cannons have lots of explosive filler, especially in the Universal belt. They are potent WW2 cannons, due to the 12 grams of TNT inside the rounds. Moreover, the seemingly small ammo count is actually made copious by the cannons' low rate of fire.
 
−
 
 
−
These cannons are always mounted in the wings of fighters. As a result, you will need to set your gun convergence to 300 m or so, as these guns have low velocity. The guns are really good for dogfighting, as they are best used up close, as many Japanese aviators say.

Compared with guns like the MG 151, the Type 99 cannons are no match. However, these cannons have better damage output than most cannons of other nations. However, there is still ongoing debate regarding the Ho-5, Japan's land based fighter standard cannon. The Ho-5 performs consistently better than the type 99, as the Ho-5 is mounted in the nose, has double the rate of fire, and is excellent at sniping pilots. However, Ho-5's have poor ammo count, so the type 99 is better for pilots who want consistent, steady, slow damage.

The Type 99 model 2 cannon is arguably better than the model 1. Although it has a lower rate of fire, the Model 2 cannon has really good belts that rip through enemy fighters. The model 2 also has improved accuracy, due to the longer barrel of the cannon.

The cannon is very useful in close range dogfights, as the rounds usually rip a wing off very quickly. It is quite easy to land shots with these cannons. The Tracer Rounds (HEF-T) only have half the explosive mass of the standard (HEF) round. Tracers do not give good damage output for this reason, and the more viable belt would be Universal, or Stealth.

General info

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

Available ammunition

Describe the shells that are available for the weapon 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 this weapon.

Usage in battles

Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.

Pros and cons

Summarise and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

HEI has good stopping power

Cons:

low velocity even for 20mm standard

low ammo count

FI ammo lack damage output result in painful stock grind

low penetration thus ineffective in ground attack role

History

Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon 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></ref>, as well as adding them at the end of the article with <references />.

Media

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

See also

Links to the articles on the War Thunder Wiki that you think will be useful for the reader, for example:

  • reference to the article about the variant of the cannon/machine gun;
  • references to approximate analogues by other nations and research trees.

External links

  • topic on the official game forum;
  • encyclopedia page on the weapon;
  • other literature.
