The Stormartillerivagn m/43 was a Swedish self-propelled assault gun. Developed in 1943 by the Swedish company Scania-Vabis, this vehicle was based on the Strv m/41 S-II chassis. The designers modified the fighting compartment, increased the thickness of the frontal armour from 25 mm to 55 mm, and installed a more powerful gun. Initially, it was planned to mount the 105 mm Bofors m/44 gun on the Sav m/43, but due to delays in the development of this gun, the first batch of vehicles in 1944 was equipped with the 75 mm Bofors m/02. A total of 36 vehicles were built. The first batch was re-equipped with 105 mm guns in 1946, and all remained in service until 1970. These self-propelled guns did not see combat.

Introduced in Update 1.97 "Viking Fury", the Sav m/43 (1946) is a fairly effective self-propelled artillery unit. It features all-round armour protection, along with good mobility and firepower, making it a powerful weapon in skilled hands, although its slow reload time somewhat offsets this.
