The German StG-44 assault rifle revolutionized warfare in 1943 — The Soviets drew inspiration from it for the AK-47

On October 15, 1943, on the Eastern Front at Velikiye Luki, Private Hans Strommeyer’s hands trembled as he inserted a curved, thirty-round magazine into a completely new weapon. This machine, officially designated the 43 submachine gun, weighed just over five kilograms and had a 419-millimeter barrel capable of firing six hundred rounds per minute.

This is neither a simple submachine gun nor a traditional rifle, but something radically new that is about to redefine the art of war. Strommeyer, who has been carrying a Karabiner 98K bolt-action rifle for two years, knows that battles rarely take place at the theoretical distances of eight hundred meters prescribed by the manuals.

The reality on the ground is far more brutal, with exchanges of fire occurring mostly at less than three hundred meters, and often even less than one hundred meters. At these short distances, the long-range, millimeter-precise accuracy of the old bolt-action rifle is irrelevant; only firepower and the volume of bullets fired matter.

The Red Army had understood this much earlier, equipping its infantrymen en masse with PPSH-41 submachine guns, which had seventy-one-round drum magazines. A single Soviet soldier could thus pin down an entire German squad, whose members had to manually cock their bolts between each shot.

The arrival of the MP43 in Strommeyer’s hands radically changed the game, as it finally offered a firing mode suited to every situation. The semi-automatic mode allowed for surgical precision, while the automatic mode ensured devastating suppression during close-quarters assaults.

The innovation also lies in its intermediate 7.92 x 33 mm cartridge, shorter than a standard rifle cartridge but more powerful than a pistol bullet. This ballistic compromise offers rifle-like range while allowing for fully controllable automatic fire by the shooter.

When Strommeyer switches the selector to automatic and pulls the trigger, the weapon rises slightly but remains stable, emptying its magazine in just three seconds. For the first time in military history, a single infantryman can deliver sustained and accurate automatic fire without needing a support team.

The assault rifle was born that day, and captured examples would soon be sent to Moscow for close study. At that time, a young tank mechanic named Mikhail Kalashnikov, recovering from his war wounds, would examine these German weapons with particular attention.

The First World War had already revealed that the rifles of the time were oversized for the actual conditions of trench warfare. Magnificent weapons like the British Lee-Enfield or the American Springfield were designed for targets located more than eight hundred meters away.

In practice, the infantry suffered sixty to seventy percent of its losses from artillery, and the remainder was primarily due to heavy machine guns. Individual rifle fire proved relatively ineffective, as the majority of engagements occurred within a radius of less than four hundred meters.

British studies conducted after 1918 confirmed that most fatal shots were fired at ranges of less than three hundred meters. The solution seemed obvious: reduce the power of the cartridge to match actual ranges, thus allowing for more ammunition to be carried.

However, military commands worldwide rejected this approach, clinging to high-powered cartridges purely out of military tradition. Germany, despite the restrictions of the Treaty of Versailles, quietly began studying intermediate munitions as early as the late 1930s.

Combat reports from Poland and France in 1939 confirmed that the Karabiner 98K had become obsolete for modern mechanized warfare. The Wehrmacht desperately needed a hybrid weapon, combining the rate of fire of a submachine gun with the stopping power of a battle rifle.

In April 1938, the army’s weapons bureau officially ordered the development of this revolutionary new weapon. The Magdeburg-based firm Polte developed the Kurz cartridge, a shortened version of the standard ammunition, offering less recoil but remaining effective at 400 meters.

Hugo Schmeisser, already famous for inventing the MP18 in 1918, then took over the development of the weapon at the Haenel company. The technical requirements were strict: the weapon had to be lighter than the K98K, accurate at medium range, and capable of firing rifle grenades.

The first prototypes, designated as the Machine Carabiner 42, emerged from the Haenel and Walther factories for testing on the Eastern Front. Approximately twelve thousand units were sent for real-world testing, and the reports from soldiers in the field were immediately and unanimously enthusiastic.

They particularly appreciated the superior firepower the weapon provided, as well as its legendary reliability in the mud and freezing cold of Russian winters. However, Adolf Hitler initially hated the project, firmly believing that victory could only be achieved through heavy weapons, tanks, and powerful artillery.

Considering the intermediate ammunition insufficient, he ordered an immediate halt to all development and demanded that the army continue using conventional ammunition. But field commanders, aware of the tactical advantage, decided to circumvent the ban through a brilliant bureaucratic ruse.

They renamed the weapon MP43, thus classifying it among the submachine guns whose global production Hitler himself had ordered to be increased. Under this code name, production could continue in secret without technically violating the Führer’s direct directives, who remained completely unsuspecting.

The final design of the MP43 incorporates major improvements such as closed-bolt firing, which greatly enhances accuracy in semi-automatic mode. Construction is simplified through the extensive use of stamped metal parts, a modern technique enabling accelerated mass production.

The first major test of its effectiveness took place in the Kholm pocket, where thirty-five parachuted prototypes enabled a small group to hold off superior Soviet forces. By the end of 1943, thousands of units had reached front-line units, and reports confirmed that the weapon functioned without any technical issues.

In April 1944, the weapon was officially renamed MP44, but the decisive turning point came during a weapons demonstration in front of Hitler himself. Impressed by the soldiers’ ability to saturate targets at four hundred meters with controlled bursts, the dictator abruptly changed his mind about the project.

It was Hitler himself who proposed the name “Sturmgewhr 44” or Assault Rifle 44, a powerful marketing term intended to galvanize the troops. This name perfectly described the weapon’s tactical role: an assault force storming enemy positions with overwhelming automatic firepower.

Between June 1943 and the end of the war in April 1945, Germany managed to produce approximately 424,000 StG-44 tanks in several different factories. While this figure seems significant, it fell far short of the initial target of four million units deemed necessary to turn the tide of the conflict.

The weapon arrived too late, just as Allied bombing raids were disrupting factories and raw materials like steel were becoming extremely scarce. Nevertheless, these 424,000 rifles were enough to forever transform the face of infantry warfare in all European theaters of operation.

The squads equipped with StG-44s demonstrated such firepower that the American and Soviet forces, still armed with older rifles, could not compete. The Soviets were the first to react seriously, studying captured examples from the initial trials by German troops as early as July 1943.

They immediately understood that the StG-44 was not a mere gadget, but a completely new category of weapon offering unique operational capabilities. The Soviet high command then ordered the immediate development of their own intermediate cartridge, the famous 7.62 x 39 mm.

As the Red Army advanced westward, it captured increasing amounts of German technical documentation and weapons engineers. By 1945, tens of thousands of Sturmgewehr assault rifles were being sent to Soviet design bureaus to be dissected by top national experts.

Mikhail Kalashnikov, born into a poor peasant family in Siberia with only seven years of education, was wounded in the shoulder in his T-34 tank in 1941. During his convalescence, a roommate asked him why the Russians only had one rifle for two men when the Germans had automatics.

The official story is that this issue inspired the wounded young man to design a revolutionary weapon out of pure patriotism from his hospital bed. While Kalashnikov possessed undeniable mechanical talent, the reality of the AK-47’s creation is far more nuanced and collaborative than is often portrayed.

In October 1946, the Soviet Union launched Operation Osoaviakhim, forcibly deporting more than two thousand German engineers and technicians to its research centers. Among them was Hugo Schmeisser himself, taken to Izhevsk, the USSR’s main center for the manufacture of small arms, where he would work until 1952.

Although Schmeisser was not technically a prisoner, he was not free to leave, and his expertise was an invaluable resource for the Soviets. Kalashnikov always denied receiving any assistance from German engineers, as propaganda demanded that the AK-47 be a purely socialist and working-class invention.

However, if we examine the evolution between the AK-46 prototype and the final production version of 1947, the similarities with the StG-44 become striking. The gas piston, initially separate, becomes integral to the bolt carrier, exactly as on the German model that Schmeisser had designed a few years earlier.

The design of the stamped metal receiver and the overall layout of the weapon betray a clear technical influence from already proven German solutions. It is not an exact copy, as the internal mechanisms differ, but rather an application of similar engineering and manufacturing principles.

The AK-47 is actually a brilliant hybrid, combining the rotating bolt of the American M1 Garand with the intermediate ammunition concept of the German StG-44. Kalashnikov managed to synthesize the best ideas from around the world to create a weapon of greater simplicity and reliability than any of its historical predecessors.

Officially adopted in 1949, the Kalashnikov rifle has become the most produced weapon in human history, with over one hundred million units in circulation. The legacy of the StG-44 is therefore not measured by its limited production, but by the pioneering concept it imposed on all modern armies.

Today, every modern assault rifle, whether it be the American M16, the French FAMAS or the Chinese Type 56, is a direct descendant of the Sturmgewehr 44. In 2017, a statue of Kalashnikov was erected in Moscow, but an embarrassing detail mistakenly showed the plans of the StG-44 instead of those of the AK-47.

This error, although quickly corrected with a grinder, reveals just how undeniable the visual and technical similarities between the two weapons remain to the discerning eye. Hugo Schmeisser died in 1953 without ever having spoken publicly about his years spent in Russia advising Soviet engineers of the time.

The StG-44 struck a perfect balance between long-range accuracy and firepower, filling the tactical gap that existed between the rifle and the submachine gun. It proved that a single soldier could change the course of a local engagement without systematically relying on heavy weaponry or a support team.

The history of these weapons is one of constant evolution, where engineering consists of taking the best existing ideas and perfecting them. The German rifle changed warfare in 1943, the Soviets drew inspiration from it for the AK-47, and together they defined modern warfare for centuries to come.

The impact of the StG-44 was not confined to the borders of Nazi Germany or the secret laboratories of Izhevsk, as its philosophy permeated every conflict since 1945. When Allied troops entered Germany, they discovered warehouses filled with these unusual weapons, whose silhouette defied the aesthetic norms of the time. American intelligence reports from 1945 described the Sturmgewehr as a weapon “clearly designed for cheap and rapid manufacture,” noting its crude and functional appearance.

However, behind this spartan appearance of stamped metal lay a profound understanding of terminal ballistics that the Americans would be slow to fully embrace. While the Soviets charged headlong into the era of intermediate ammunition with the AK-47, the United States remained shackled to the power of the .30-06 caliber, and later the 7.62 NATO. They still clung to the myth of the sniper capable of taking down an enemy at 500 meters, ignoring the lessons of the Wehrmacht regarding the volume of fire required in urban combat.

This Western cultural resistance led to the creation of the M14, a magnificent rifle but ill-suited to the jungles of Southeast Asia, where combat was fought at close range. Faced with the AK-47s supplied by the Soviets, American soldiers found themselves with a weapon that was too long, too heavy, and whose automatic fire was virtually impossible to control. It was the ghost of the StG-44 that returned to haunt the Pentagon in the rice paddies of Vietnam, forcing a belated and rushed adoption of the modern assault rifle concept.

Eugene Stoner’s switch to the 5.56mm caliber and the AR-15 was essentially a modernized and streamlined version of Hugo Schmeisser’s original 1942 design. It retained the high-capacity magazine, ergonomic pistol grip, and selective-fire capability, proving the German concept’s universal superiority. Even the straight stock design to compensate for recoil, already present on the FG-42 and perfected on the StG, became the undisputed global standard for small arms.

In the 1950s, Spain became an unlikely haven for this German technological legacy, welcoming engineers from Mauser who had fled denazification. Under the name CETME, these technicians developed a rifle that used a roller-locking system, a direct evolution of post-war research. This design was later acquired by Heckler & Koch in West Germany, giving rise to the renowned G3, one of the most robust rifles in the world.

The G3, although chambered in a high-powered caliber, retained the manufacturing DNA of the StG-44, utilizing stamped metal to enable efficient mass production. During the Cold War, the world was divided between AK-47 users in the East and G3 or FN FAL users in the West, all spiritual descendants of the Sturmgewehr. Every shot fired in Angola, Nicaragua, or Afghanistan carried within it the genes of this major technological innovation born in the Suhl factories.

The 7.92 mm Kurz cartridge also paved the way for a new science of ballistics, seeking the balance between ammunition weight and kinetic energy. Engineers realized that carrying twice as much lightweight ammunition was tactically more advantageous than carrying a few heavy, cumbersome bullets. This logic radically changed military logistics, allowing squads to remain self-sufficient longer on the battlefield without constant resupply.

Schmeisser’s influence extends even to the design of modern submachine guns, which had to adapt to avoid being overshadowed by the versatility of the assault rifle. The MP5, for example, although using pistol ammunition, retains the modular structure and manufacturing methods proven on the 1944 prototypes. The idea that a precision weapon could be assembled from folded sheets of steel was the true industrial revolution of the 20th century’s military.

Beyond its technical aspects, the StG-44 imposed a new tactical doctrine based on the “fire and movement” principle, pushed to its technological extreme. The infantryman was no longer a mere pawn awaiting orders, but a mobile firepower unit capable of saturating an area in seconds. This combat autonomy forced officers to rethink command at the section level, giving more responsibility to non-commissioned officers in the field.

The weapon’s aesthetics, with its banana-shaped magazine and aggressive silhouette, have become a cultural icon, symbolizing modern military power in the collective imagination. It appears in countless films and video games, often misidentified, but always recognized for its menacing and avant-garde appearance for its time. This enduring fascination proves that Schmeisser’s design captured the very essence of what the tool of the soldier of the future should be.

It is fascinating to note that even eighty years later, special forces around the world are using platforms that are merely refinements of the original concept. Modern optics, mounting rails, and composite materials have not altered the fundamental structure of the weapon conceived under the bombs in 1943. The Sturmgewehr was so far ahead of its time that it took several decades for global military doctrine to catch up with its actual capabilities.

Debates about the true origin of the AK-47 will continue to rage among historians, but the intellectual influence of the German model on Kalashnikov is a technical fact. Even if the internal locking mechanisms differ radically, the external architecture and ergonomics cannot be the result of pure chance or evolutionary convergence. Soviet engineering had the foresight not to blindly copy, but to adapt the concept to the brutal production realities of the Ural factories.

The legendary robustness of the AK-47 stems from the fusion of Schmeisser’s vision and the need for simplicity demanded by Stalin’s marshals. Where the StG-44 was still somewhat complex and prone to spring failures, the Russian model simplified every component, rendering it virtually indestructible. Perhaps the greatest tribute paid to the German inventor is seeing his idea brought to such widespread global adoption by his former enemy.

The StG-44 remains a silent witness to an era when technological necessity shattered the barriers of even the most conservative military traditions in history. It survived the fall of the Third Reich only to be reborn in a thousand different forms across all continents, from the Middle East to Latin America. Every assault rifle rolling off a modern assembly line today is a descendant, whether consciously or not, of that steel machine born in the turmoil of 1943.

Ultimately, the story of the Sturmgewehr 44 is that of an idea too powerful to be stifled by bureaucracy or the prejudices of a dictator. It now belongs to the world’s heritage of weaponry, a reminder that innovation is never the work of a single individual, but rather the result of a slow accumulation of knowledge. Strommeyer’s rifle at Velikiye Luki was merely the first cry of a new era that continues to resonate on the battlefields of the twenty-first century.
