Sturmhaubitze 42, Sd.Kfz 142/2 Initial Production

In 1942, a variant of the StuG III Ausf. F was designed with a 105 mm (4.1 in) howitzer instead of the 7.5 cm StuK 40 L/43 cannon. These new vehicles, designated StuH 42 (Sturmhaubitze 42, Sd.Kfz 142/2), were designed to provide infantry support with the increased number of StuG III Ausf. F/8 and Ausf. Gs being used in the anti-tank role. The StuH 42 mounted a variant of the 10.5 cm leFH 18 howitzer, modified to be electrically fired and fitted with a muzzle brake. Production models were built on StuG III Ausf. G chassis. The muzzle brake was often omitted due to the scarcity of resources later in the war. ~1,299 StuH 42 were produced by Alkett from March 1943 to 1945, the initial 12 vehicles were built on repaired StuG III Ausf. F and F/8 from autumn 1942 to January 1943.
