Dragon 1/72 Diecast Armor, 60357, German 10.5 cm StuH.42 Ausf G, Unidentified Unit, Germany, 1945

Design

With the StuG IIIs getting the longer 7.5cm gun, there was still a need for close support weapons for anti-personnel.4

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

Armament

It originally had an electrically fired 10.5 cm 1918 light field howitzer (10.5 cm le FH184), 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

Prototype

The first prototype was completed in March 1942.

Production

  • StuH 42: 1,210
    • Production: 1942 - ?4

Variants

  • StuH 42 Ausf F; Sturmhaubitze 42 Ausf F: Had the 10.5cm le FH 18 howitzer.4
