Akan m/39A (12.7 mm)
Contents
Description
The 12.7 mm Akan m/39A is a Swedish aircraft machine gun. It is equipped on some of their early jet fighters.
The Akan m/39A, originally based on the Browning machine gun, was a conversion of the license-produced 13.2 mm Hotchkiss-cartridge chambered Akan m/39A back into the original 12.7x99 mm (or .50 BMG) cartridge.

General info
The 12.7 mm Akan m/39A was basically a rebarrelled version of the 13.2 mm Akan m/39A. The gun had all the same proportions and technical details but was rebarrelled to the more common Browning .50 cal (12.7 x 99 mm) ammunition instead of the worldwide less common Hotchkiss calibre of .52 in (13.2 x 99 mm). 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 calibre) the Akan m/39A featured a modified electrical firing mechanism rating it from 600 rpm to 1500 rpm. The gun was used as secondary armament for tanks with a reduced rate of fire (720 rpm) 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 1080 rpm.
