Vehicles equipped with this weapon

General info

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

Available ammunition

Default

The default belt alternates between the API-T (Armour-piercing incendiary tracer) and HEF-I (High-explosive fragmentation incendiary) shells.

Air targets

The Air targets belt alternates between 2 HEF-I shells and 1 API-T shell.

Armoured targets

The Armoured targets belt alternates between 2 API-T shells and 1 HEF-I shell.

Comparison with analogues

Compared to the Russian Gsh-23L cannon, the Oerlikon supports a bigger penetrating power (29 mm to Oerlikon's 53 mm with the AP belts).

Usage in battles

Air-To-Air combat

The Oerlikon is great at dealing with enemy aerial targets. It has great fire rate and muzzle velocity making hitting the enemy much easier.

Ground targets

Due to the decent penetration the Oerlikon offers with the API-T shell, it can be used to deal with lightly armoured AFVs and can penetrate the tops of enemy MBTs.

Pros and cons

Pros:

  • Great damage against aerial targets
  • Good penetration values
  • Great firerate

Cons:

  • Usually hull mounted on a helicopter, making it hard to aim.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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

Excellent additions to the article would be video guides, screenshots from the game, and photos.
