Description

The 20 mm Akan m/45, short for Automatkanon m/45, was developed by Bofors during the Second World War and replaced Akan m/40, which had a low fire rate of only 360 rounds per minute, and Akan m/41, that suffered from unreliability and low ammo capacity. It only completed development after the war had ended, after which it was decided to purchase the cheaper British surplus Hispano Mk.II and Mk.V cannons along with de Havilland Vampires, thus the m/45 only saw service on the J21 and J21R series of aircraft.

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.

Cons:

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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

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
