History

The Akan m/41A is a Swedish licensed version of the French Hispano 404 20mm autocannon. The 404 came into existence when Hispano-Suiza was assigned to develop a 20mm cannon that could fit through the propeller shaft of an inline aircraft engine. To accomplish this task, Hispano-Suiza used a modified version of the Oerlikon FF that was being produced under license that became the Hispano HS.9. However, Oerlikon entered a patent dispute with Hispano-Suiza and lost their license forcing the later company to restart development of the "moteur-canon" for the French. Marc Brikigt, Hispano's chief engineer used a new gas-operation locking bolt action for the cannon based on 1919 patent from an American machine gun designer for the 404 instead of the Oerlikon advanced primer ignition blowback action. The new cannon had a lighter bolt and was lighter in weight overall which made it ideal for mounting on ground vehicles as an anti-aircraft cannon. It was in this role the HS.404 got the attention of Sweden who received a license to make the cannon as the Lvakan m/41. An aircraft mounted variant the m/41A would followed and was used the T18B torpedo bomber and the J21A-1fighter plane.
