History
The Lvakan m/36 is the Swedish Army designation for the Bofors L/60 anti-aircraft auto-cannon which was originally built for the Swedish Navy. Based off the design of a 57mm anti-torpedo boat weapon from the late 1800s, the prototype of the Bofors L/60 was developed to replace the British 2pdr QF Mk.IIc "pom-poms" adopted by Swedish in 1922. It would take a decade of development before the Bofors company was able to make a reliable gun that could sustain a good rate of fire, but it was accepted in 1933 as the 40mm akan M/32. Firing a 2 pound 40x133mm high explosive shell at 2,960 feet per second, the gun had an advanced sighting system with a 6 Volt battery powered reflector sight and a simple mechanical computer that adjusted for lead. The official rate of fire was 120 rounds per minute, but the practical rate was closer to 80-100 rpm due to the gravity fed four clips needed to load the gun. Originally intended as a dual-purpose gun for submarines, the Swedish Navy ended up changing their minds and instead requested a smaller hand-traversed 25mm design. The first country to actually adopt the gun was the Netherlands who mounted the design on the cruiser the De Ruyter in August 1934. In April of 1935, Bofors presented their new carriage for a ground-based variant of the gun in Belgium. That August, they got orders from Poland, Finland and Norway, who all set up factories for licensed production. The next year, the gun would be adopted by the Swedish Army as the Lvakan m/36. During World War II Sweden would experiment with self-propelled anti-aircraft vehicles. Having no tank chassis capable of of supporting the Lvakan m/36, they mounted it on a Volvo truck to create the Lvtdgb m/40. The Bofors 40mm gun with its superior medium range capabilities, won against the smaller Pvlvv fm/42 with it smaller 20mm Lvakan m/40B Bofors gun, but development would continue until after the war. However, they would make the L-62 ANTI I and ANTI II which respectively saw service in Hungary and Finland during World War II.
