We recently told you about the Swedish “reserve”: the Strv m/31 light tank. Landsverk’s work on this tank resulted in a project with the factory designation L-60, where the mistakes the m/31’s trials had encountered were taken into consideration – including, among other things, problems with the suspension. The enhanced tanks were put into service under the designation Strv m/38, and Landsverk was commissioned to manufacture a series of these tanks. All 16 tanks of the m/38 series were Sweden’s only armoured vehicles when WWII erupted in Europe. However, the military wasn’t thoroughly satisfied with these vehicles – and, on top of that, they needed a whole lot more of them. The outcome of future upgrades in the L-60 project were two new models: the Strv m/39 and the Strv m/40. They received a turret with a new shape, a fully upgraded engine compartment, and a set of add-on hull armour. The m/40 was equipped with an automatic gearbox and an enhanced frontal turret section to which another machine gun, not paired to the cannon, was added. The Strv m/40 was manufactured until March 1942. A total of about 100 units of this modification were released.
