Design

With the StuG IIIs getting the longer 7.5cm gun, there was still a need for close support weapons for anti-personnel.

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.

Armament

It originally had an electrically fired 10.5 cm 1918 light field howitzer (10.5 cm le FH18), with a muzzle brake, installed. In 1944, the muzzle brake was deleted to economize on production.

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

Prototype

The first prototype was completed in March 1942.

Production

  • StuH 42: 1,210
    • Production: 1942 - ?

Variants

  • StuH 42 Ausf F; Sturmhaubitze 42 Ausf F: Had the 10.5cm le FH 18 howitzer.
  • StuH 42 Ausf G; 10.5cm Sturmhaubitze 42 Ausf G; Sturmgeschütz III mit 10.5cm StuH 42 L/28.3; StuG III fur 10.5cm StuH 42: Had the 10.5 StuH 42 L/28. Late models had no muzzle brake. Had remote controlled machine gun. A few had the Saukopf gun matle.

Usage

From 1943 these were issued to Sturmgeschütz detachments. At Kursk there were 68 available to Army Groups Center and South.
