In January 1942, Hitler ordered the development of a multi-purpose infantry support weapon that could also operate against tanks. The Hummel (bumblebee) emerged as an interim solution for this project. It is a hybrid design based on a Pz.Kpfw.III/IV chassis fitted with the huge 15cm sFH18/1 howitzer. It comprised three sections, from front to rear, driving compartment, engine room and finally open fighting compartment at rear.
It was intended as a long-range fire support weapon and given this role, there is scant information about their performance.
However, the Hummels continued to be used throughout the war on both western and eastern fronts which testifies to their value to German combat units.
