Historical Information for StuG IV

The Sturmgeschütz IV resulted from Krupp’s effort to supply an assault gun. As Krupp did not build Panzerkampfwagen III's they used the Panzerkampfwagen IV chassis in combination with a slightly modified Sturmgeschutz III superstructure. From December 1943 to May 1945, Krupp built 1,108 StuG IVs and converted an additional 31 from battle-damaged Panzer IV hulls.

The StuG IV became known as an effective tank killer, especially on the Eastern Front. The variant was constantly plagued by supply shortages due to other production lines and allied bombing runs. Losing favour with German industries due to devolpment costs and much needed proven designs such as the Sturmgeschütz III, production was slowed and the remaining uncompleted hulls at the factory sites were scrapped by allied forces in 1945.

It had a four-man crew, and was issued mainly to infantry divisions.

  • Commander in hull left rear
  • Gunner in hull left center
  • Loader in hull right rear
  • Driver in hull left front


To date it is known that 2 working StugIV’s are in existence.
