From December 1943 to May 1945, Krupp built 1,108 StuG IVs and converted an additional 31 from battle-damaged Panzer IV hulls. While the number is smaller than the 9000+ StuG III, the StuG IV supplemented and fought along with StuG III during 1944-45, when they were most needed.

- Initial Project The first known proposal for a Sturmgeschütz on the Panzer IV chassis is in Krupp drawing number W1468 dated February 1943. This initial drawing unitized the outdated Sturmgeschütz Ausf. F superstructure on a Panzer IV chassis 9. This proposal had a sloped front superstructure with a combat weight of 28.26 tons. Krupp abandoned it in February 1943 because it was too heavy. Plans for the StuG IV were halted.
- Another Project During the Führer Conference of August 19–22, 1943, after the battle of KurskBattle of KurskThe Battle of Kursk took place when German and Soviet forces confronted each other on the Eastern Front during World War II in the vicinity of the city of Kursk, in the Soviet Union in July and August 1943. It remains both the largest series of armored clashes, including the Battle of Prokhorovka,...
, Hitler had seen reports of the StuG III performing superior to the Panzer IV within certain restraints of how they were deployed. Convinced that a tank-hunter version would be superior to the tank version, Hitler planned to switch Panzer IV production to "Panzerjäger IV" production as soon as possible. It was to mount the same 7.5 cm L/70 used for the Panther. Another manufacturer, Vomag built a prototype Panzerjäger IV with 7.5 cm L/48 gun and demonstrated it on October 20, 1943. It was later re-designated as Jagdpanzer IVJagdpanzer IVThe Jagdpanzer IV, Sd.Kfz. 162, was a tank destroyer based on the Panzer IV chassis built in three main variants. As one of the casemate-style turretless Jagdpanzer designs, it was developed against the wishes of Heinz Guderian, the inspector general of the Panzertruppen, as a replacement for the...
Ausf. F. As the Jagdpanzer IV was already being produced by Vomag, the StuG IV may not have materialized, had it not been for the major disruption of StuG III production, and the scarce supply of the 7.5 cm L/70 gun designated for the Jagdpanzer IV.
- Restart of the StuG IV In November 1943, Alkett, a major StuG III manufacturer, was bombed. Alkett produced 255 StuG III in October 1943, but in December fell to just 24 vehicles. On December 6–7, 1943, at a conference with Hitler, he welcomed the suggestion of taking the StuG III superstructure and mounting it on a Panzer IV chassis. The StuG IV could be more quickly manufactured than the Jagdpanzer IV at the time. This re-started the Sturmgeschütz IV project. This time, the superstructure of the StuG III Ausf. G was mounted on a Panzer IV chassis 7, with a box compartment for the driver added. Combat weight was 23000 kg, lighter than the 23900 kg for the StuG III Ausf. G. On Dec. 16-17, 1943, Hitler was shown the StuG IV, and approved it. To make up for the large deficit in StuG III production, StuG IV production received full support.
From December 1943 to May 1945, Krupp built 1,108 StuG IVs and converted an additional 31 from battle-damaged Panzer IV hulls. While the number is smaller than the 9000+ StuG III, the StuG IV supplemented and fought along with StuG III during 1944-45, when they were most needed.

Surviving vehicles
There are presently three surviving examples of the StuG IV, two in Poland and one in Latvia. One vehicle held by the Muzeum im. Orla Bialego is a makeshift restoration using a StuG IV hull and various parts from Stug III:s and Pz IV:s. The other Polish StuG IV, held by the Museum of Armoured Weapon in Poznań, is complete and in running condition. In October 2011, a restored Latvian StuG IV of unknown provenance was offered for sale on milweb.net at an asking price of 490,000 Euros, although no engine or gearbox is included.External links
