General info

The 12.7mm Akan m/39A was basically a rebarrelled version of the 13.2mm Akan m/39A. The gun had all the same proportions and technical details but was rebarrelled to the more common Browning .50in (12.7x99mm) ammunition instead of the worldwide less common Hotchkiss caliber of .52in (13.2x99mm). Since 12.7 mm ammunition was cheaper to buy than the cost to produce new 13.2 mm ammunition, all 13.2 mm weapons were re-chambered during the post-war era, and after 1950 basically all Swedish weapons fired the new cartridge. Other specifications remained unchanged.

Commonly mistaken with the Browning M2 (due to the same caliber) the Akan m/39A featured a modified electrical firing mechanism rating it from 600rpm to 1500rpm. The gun was used as secondary armament for tanks with a reduced rate of fire (720rpm) as well as standard armament for a variety of swedish late- and post-WW2 aircraft such as the Saab 18, Saab 21, and the predecessor FFVS J22B with a rate of 1080rpm.

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 If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: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