The MP40, often synonymous with the mechanized horror of World War II, represents a distinct evolution in personal infantry weaponry. To understand its precise origin requires looking beyond the common misconception of its birth year and examining the specific context of its design and production. The question of when the MP40 was made is not a single date but a timeline stretching from early theoretical concepts in the aftermath of World War I to the final units rolling off the production lines in the closing years of the Second World War. Its creation was driven by a need for a more effective and efficient weapon for Germany's rapidly expanding army.
From Theory to Tactical Doctrine
Before the MP40 existed in its iconic form, German military theorists were already dissecting the lessons of the previous global conflict. The limitations of bolt-action rifles in the close-quarters chaos of trench warfare were evident, and the potential of submachine guns, like the British Sten and the German Bergmann MP18 from World War I, was being closely studied. The German Army, the Heer, began to formalize a new approach to infantry combat that emphasized speed, volume of fire, and maneuverability for non-commissioned officers and squad leaders. This evolving tactical doctrine created the precise battlefield role that the future MP40 was designed to fill, bridging the gap between a rifle and a true automatic weapon.
The Early Prototypes and the EMP36
The lineage of the MP40 can be traced back to the EMP36, a rather unconventional and expensive submachine gun designed by Heinrich Vollmer. Only a small number of these prototypes were ever produced, but they provided the crucial groundwork for what was to come. The lessons learned about balancing cyclic rate of fire, reliability with the 9x19mm Parabellum cartridge, and the overall handling characteristics were directly applied to the next generation of designs. This period of development in the late 1930s was about proving the concept of a mass-producible, high-rate-of-fire weapon that could be manufactured with the industrial capacity of Nazi Germany.
Enter the MP38: The Precursor
The first true step on the path to the MP40 was the Maschinenpistole 38, or MP38. Introduced in 1938, it was a revolutionary design for its time, largely constructed from stamped and machined steel components rather than the traditional milled wood and metal of earlier guns like the MP18. This innovative use of materials was not just a cost-saving measure; it was a strategic necessity to speed up production and conserve resources for a war that seemed increasingly inevitable. The MP38 was a complex and expensive weapon to produce, which is where its successor, the MP40, would bring further refinement.
The Refinement: The Birth of the MP40
The MP40 was not a radical redesign but a clever evolution, an exercise in simplification. Officially designated as the Maschinenpistole 40, its development and initial production ramped up significantly around 1940, hence the name. Engineers took the proven, successful MP38 design and methodically reduced its complexity. The most significant change was the replacement of the MP38’s wooden stock with a distinctive telescoping "paratrooper" stock made from metal stampings, and the careful substitution of more stampings for milled parts. This was done to further cut down on the use of skilled labor and precious materials like high-grade steel and wood, allowing for a much faster and cheaper manufacturing process.
