Tank origin

After canceling production on the Strv m/31, the Swedish company AB Landsverk started developing a new tank for export. Based on designs for the promising L-60 project, the vehicle’s dimensions were increased and its weight grew to 15 tons. The first plans for the vehicle appeared in 1936, and featured both the Austrian Böhler M35 47 mm anti-tank gun and the Schwarzlose M. 07/12 machine gun. The frontal armor was around 34 mm thick. Initially, the vehicle was designated as LAGO and intended for the Austrian army. Later, there were plans for it to be sent to Hungary with the same armament. However, none of these deals went through. The vehicle had similar characteristics to those of the German Pz.Kpfw. III and it had export potential, but by 1940, the original designs had undergone significant changes. A year later, the Swedish military showed interest in the vehicle.
