In November 1943, Alkett, GmbH, a major StuG III manufacturer, was bombed as part of the RAF campaign against Berlin, and Alkett's StuG production declined from 255 StuG IIIs in October 1943, to just 24 vehicles in December. In a December 1943 conference, Hitler welcomed the suggestion of taking the StuG III superstructure and mounting it on a Panzer IV chassis to offset the loss of production of the StuG III. This restarted the Sturmgeschütz IV project, which had earlier been considered and rejected.
