In 1943, the Wehrmacht were experiencing a dire shortage of StuG III tank destroyers because the joint U.S.A.-U.K. air raids caused considerable damage to the Alkett company's factory that produced these vehicles. December 1943, a decision was made to utilize the working capacities of the BMM company in Prague to start production of tank destroyers.
