Stormartillerivagn m/43 (Sav m/43) (English: Assault artillery carriage model 1943) was an assault gun based on Stridsvagn m/41 SII chassis, a Swedish development of a license-built Czechoslovak TNH medium tank. The Sav m/43 was first armed with a 75 mm gun; later they were rearmed with a 105 mm m/44 gun.
The Sav m/43 was used by the artillery in A9 Regiment at Kristinehamn. In 1951, they were transferred to the armored forces. With one Sav m/43 used in training, they were allocated to infantry assault gun companies with six assault guns in each brigade. They were phased out of active service in 1973.
