Design

The first prototype was completed in March 1942. Was based on the same hull and superstructure as the StuG III Ausf F, StuG III Ausf F/8, and StuG III Ausf G. The improvements made during production for the StuG III Ausf G were also made to the StuH 42. 10% of production was dedicated to the StuH 42.2

It originally had an electrically fired 10.5 cm 1918 light field howitzer, with a muzzle brake, installed.2 In 1944, the muzzle brake was deleted to economize on production.2

The 105 mm gun fired a 32.7 lb at a velocity of 1,772'/sec to a range of 9,077 yards.3
