StG 44

The StG 44 (abbreviation of Sturmgewehr 44, "assault rifle 44") is a German selective-fire assault rifle developed during World War II by Hugo Schmeisser. It is also known by its early designations as the MP 43 and MP 44 ("Maschinenpistole 43" and "44"). The StG 44 was an improvement of an earlier design, the Maschinenkarabiner 42(H).
The StG 44 was the first successful assault rifle, with features including an intermediate cartridge, controllable automatic fire, a more compact design than a battle rifle with a higher rate of fire, and being designed primarily for hitting targets within a few hundred metres. Other rifles at the time were designed to hit targets of over a thousand meters, but this was found to be in excess of the range in which most enemy engagements actually took place.
The StG 44 fulfilled its role effectively, particularly on the Eastern Front, offering a greatly increased volume of fire compared to standard infantry rifles. The StG largely influenced the Soviet AK-47, introduced three years after the war concluded. The StG's influence can still be seen in modern assault rifles, which, after World War II, became the global standard for infantry rifles.
Description.
MP 43, MP 44, and StG 44 were different designations for what was essentially the same rifle with minor updates in production. The variety in nomenclatures resulted from the complicated bureaucracy in Nazi Germany. Developed from the Mkb 42(H) "machine carbine", the StG 44 combined the characteristics of a carbine, submachine gun, and automatic rifle. StG is an abbreviation of "". According to one account, the name was chosen personally by Adolf Hitler for propaganda reasons and means "assault rifle" as in "to assault an enemy position", although some sources dispute that Hitler had much to do with coining the new name besides signing the order. After the adoption of the StG 44, the English translation "assault rifle" became the accepted designation for this type of infantry small arm. Over the course of its production, there were minor changes to the butt end, muzzle nut, shape of the front sight base and stepping of the barrel.
The rifle was chambered for the 7.92×33mm Kurz cartridge. This shorter version of the German standard (7.92×57mm) rifle round, in combination with the weapon's selective-fire design, provided a compromise between the controllable firepower of a submachine gun at close quarters with the accuracy and power of a Karabiner 98k bolt-action rifle at intermediate ranges. While the StG 44 had less range and power than the more powerful infantry rifles of the day, Army studies had shown that few combat engagements occurred at more than and the majority within . Full-power rifle cartridges were excessive for most uses for the average soldier. Only a trained specialist, such as a sniper, or soldiers equipped with machine guns, which fired multiple rounds at a known or suspected target, could make full use of the standard rifle round's range and power.
The British were critical of the weapon, saying that the receiver could be bent and the bolt locked up by the mere act of knocking a leaning rifle onto a hard floor. A late-war U.S. assessment derided the StG-44 as "mediocre", "bulky" and "unhandy", declaring it incapable of sustained automatic fire and prone to jamming, though the report accepted that its accuracy was "excellent for a weapon of its type".
History.
Background.
In the late 19th century, small-arms cartridges had become able to fire accurately at long distances. Jacketed bullets propelled by smokeless powder were lethal out to . This was beyond the range a shooter could engage a target with open sights, as at that range a man-sized target would be completely blocked by the front sight blade. Only units of riflemen firing by volley could hit grouped targets at those ranges. That fighting style was taken over by the widespread introduction of machine guns, which made use of these powerful cartridges to suppress the enemy at long range. Rifles remained the primary infantry weapon, but in some forces were seen as a secondary or support weapon, backing up the machine guns.
This left a large gap in performance; the rifle was not effective at the ranges it could theoretically reach while being much larger and more powerful than needed for close combat. Weapons for short-range use existed, initially semi-automatic pistols and, later, automatic submachine guns. These fired pistol rounds which lacked power, accuracy, and range. They were only useful at very short ranges of no more than . This led to extensive research into creating an intermediate round to fill this gap. This type of ammunition was being considered as early as 1892, but militaries at the time were still fixated on increasing the maximum range and velocity of bullets from their rifles.
Earlier development.
In early 1918, Hauptmann (Captain) Piderit, part of the "Gewehrprüfungskommission" ("Small Arms Examination Committee") of the German General Staff in Berlin, submitted a paper arguing for the introduction of an intermediate round in the German Army with a suitable firearm. He pointed out that firefights rarely took place beyond , about half the sight line range of the 7.92×57mm round from a Mauser Gewehr 98 rifle or less for MG 08 machine gun. A smaller, shorter, and less powerful round would save materials, allow soldiers to carry more ammunition, and increase firepower. Less recoil would allow semi-automatic or even fully automatic select-fire rifles, although in his paper he called it a "Maschinenpistole" (submachine gun). The German Army showed no interest, as it already had the MP 18 submachine gun firing 9 mm pistol rounds and did not want to create a new cartridge.
In 1923, the German Army set out requirements for a Gewehr 98 replacement. It had to be smaller and lighter than the Mauser, have similar performance out to , and have a magazine with a 20- or 30-round capacity. The Bavarian company Rheinisch-Westfälische Sprengstoff (RWS) experimented with rounds in the 1920s, and German companies developing intermediate ammunition for aerial machine guns showed interest. Development of the future infantry rifle did not start until the 1930s. RWS offered two rounds, one with a 7 mm bullet and one with an 8 mm bullet, both in a 46 mm case. The German company Deutsche Waffen und Munitionsfabriken had the 7×39.1mm round, and Gustav Genschow & Co (Geco) proposed a 7.75×39.5mm round. Geco's automatic carbine was the Model A35, a further development of the SG29 semi-automatic rifle. The weapon was complicated and unsafe to handle.
The German government started its own intermediate round and weapon program soon after. German ammunition maker Polte of Magdeburg was commissioned to develop the rounds in April 1938 and signed a contract with the Heereswaffenamt (HWA). At the same time, the HWA contracted C. G. Haenel of Suhl to create a weapon for the round. HWA requirements were for a rifle that was shorter and with equal or less weight to the Kar 98k and as accurate out to ; and be select-fire with a rate of fire under 450 rounds per minute. It should be rifle grenade compatible, reliable, maintainable, and have a "straightforward design". Fifty rifles were to be delivered for field testing in early 1942.
At the start of World War II, German infantry were equipped with weapons comparable to those of most other military forces. A typical infantry unit was equipped with a mix of bolt-action rifles and some form of light, medium or a general-purpose machine guns. A problem with this mix was that the standard rifles were too large to be effectively used by mechanized and armored forces, where they were difficult to maneuver in the cramped spaces of an armored vehicle. Submachine guns, such as the MP 28, MP 38, and MP 40 were issued to augment infantry rifle use and increase individual soldiers' firepower, but lacked range and accuracy beyond .
New requirements.
During the invasion of the Soviet Union, increasing numbers of semi-automatic Tokarev SVT-38 and SVT-40s were used by the Red Army – mostly elite units and non-commissioned officers – while some Soviet rifle companies were completely equipped with PPSh-41 submachine guns.
After experiencing high volumes of automatic fire from these weapons, German commanders re-thought their small arms requirements. The German army had been attempting to introduce semi-automatic weapons such as the Gewehr 41, but these proved troublesome in service, and production was insufficient to meet requirements. Several attempts had been made to introduce lightweight machine guns or automatic rifles, but recoil from the powerful 7.92×57mm Mauser round was too difficult to control in automatic fire.
By 1941, it was becoming clear that action needed to be taken. Although various experimental rounds had been developed to one degree or another by this point, the Army instead decided to select yet a new design, the Polte 8×33mm "" ("short cartridge"). This used a spitzer bullet and basic cartridge design of the standard 7.92×57mm Mauser rifle cartridge, cutting down the cartridge from the original 7.92×57mm Mauser to 7.92×33mm Kurz. It was understood that this was not ideal, but it would minimize logistical problems.
Design influences.
The German 7.92×57mm Mauser chambered FG 42 battle rifle/automatic rifle was one of the first inline firearms incorporating a "straight-line" recoil configuration and an elevated sight line over the bore axis. The inline design helps reduce muzzle rise during automatic fire.
MKb 42(H) & MKb 42(W).
Contracts for rifles firing the 7.92×33mm Kurz round were issued to both Walther and Haenel (whose design group was headed by Hugo Schmeisser), were asked to submit prototype weapons under the name ' 1942 ("machine carbine") or MKb 42"'. Both designs were similar, using a gas-operated action, with selective fire. Since both rifles shared the title of Maschinenkarabiner 42 the letters (H) and (W) were added to differentiate the two. In this case (H) and (W) were the first initial of each guns manufacturer "Haenel Waffen und Fahrradfabrik" and "Walther Waffenfabrik AG". The MKb 42(H) along with the less successful MKb 42(W) were predecessors of the later MP 43, MP 44, StG 44. The majority of the MP 43's features came from the MKb 42(H), with the hammer firing system and closed bolt coming from the MKb 42(W).
MP 43, MP 44, StG 44.
As work moved forward to incorporate this new firing system, development halted when Hitler suspended all new rifle programs due to administrative infighting within the Third Reich. Hitler ordered that newer submachine guns were to be built, and he strongly disagreed with the use of the "Kurz" ammunition. To keep the MKb 42(H) development program alive, the "Waffenamt" (Armament Office) re-designated the weapon as the Maschinenpistole 43 (MP 43) and, making a few improvements, billed the weapon as an upgrade to existing submachine guns.
Much time was wasted trying to make the MP 43 a replacement for the Karabiner 98k rifle. This goal was eventually realized to be impossible; the MP 43 cartridge was too weak to fire rifle grenades, too inaccurate for sniping, and the weapon was too short for bayonet fighting. In September 1943, it was decided that the MP 43 would supplement rather than replace the Kar 98k. As a result, the optical sight base, grenade-launching extended muzzle thread, and bayonet lug were removed.
Adolf Hitler eventually discovered the designation deception and halted the program again. In March 1943, he permitted it to recommence for evaluation purposes only. Running for six months until September 1943, the evaluation produced positive results, and Hitler allowed the MP 43 program to continue in order to make mass production possible. The weapon made extensive use of (for the 1940s) advanced cost-saving pressed and stamped steel components rather than machined parts. The first MP 43s were distributed to the Waffen-SS; in October 1943, some were issued to the 93rd Infantry Division on the Eastern Front. Production and distribution continued to different units. In April 1944, Hitler took some interest in the weapon tests and ordered the weapon (with some minor updates) to be re-designated as the MP 44. In July 1944, at a meeting of the various army heads about the Eastern Front, when Hitler asked what they needed, a general exclaimed, "More of these new rifles!". The exclamation caused some confusion (Hitler's response is reputed to have been "What new rifle?"), but once Hitler saw the MP 44 being demonstrated, he was impressed and gave it the title "Sturmgewehr". Seeing the possibility of a propaganda gain, the rifle was again renamed as the Sturmgewehr 44 (StG 44), to highlight the new class of weapon it represented. The designation translates to "Assault rifle, model 1944", thereby introducing the term "assault rifle".
A common belief of Hitler's influence over the Sturmgewehr was that he was against an intermediate rifle round. In reality, he could have ordered the project to be canceled entirely if he wanted to, especially if it had been hidden from him. Numerous reports and company correspondence reveal frequent presentation of the rifle's stages of development to Hitler. Rather than being opposed to the entire idea, his apprehension seemed to be from reluctance to send a new weapon to the front in too small numbers. Industry would not be able to replace some 12 million Kar 98k rifles in a short time, and the already strained logistics structure would have to support another cartridge. While the Sturmgewehr required specialized tooling to manufacture it, it consumed less materials and was faster and easier to make than a Kar 98k. Without suppliers to quickly produce components, companies could not manufacture sufficient numbers to replace the Kar 98k quickly. Introducing the new assault rifle in quantities that would not make an impression on the front would be counter-productive. Hitler instead wanted to introduce it on the largest scale possible, which has been misinterpreted as his resistance to new technology.
Production soon began with the first batches of the new rifle being shipped to troops on the Eastern Front. By the end of the war, a total of 425,977 StG 44 variants of all types were produced and work had commenced on a follow-on rifle, the StG 45. The assault rifle proved a valuable weapon, especially on the Eastern front, where it was first deployed. A properly trained soldier with a StG 44 had an improved tactical repertoire, in that he could effectively engage targets at longer ranges than with an MP 40, but be much more useful than the Kar 98k in close combat, as well as provide covering fire like a light machine gun. It was also found to be exceptionally reliable in extreme cold. The StG 44's rate of fire was 540 rpm.
A primary use of the MP 44/StG 44 was to counter the Soviet PPS and PPSh-41 submachine guns, which used the 7.62×25mm Tokarev round. These cheap, mass-produced weapons used a 71-round drum magazine or 35-round box magazine and though shorter-ranged than the Kar 98k rifle, were more effective weapons in close-quarter engagements. The StG 44, while lacking the range of the Kar 98k, had a considerably longer range than the PPS/PPSh submachine guns, more power, an ability to switch between a fully automatic and a default semi-automatic fire mode and surprising accuracy. The StG 44 was an intermediate weapon for the period; the muzzle velocity from its barrel was , compared to of the Karabiner 98k, of the British Bren, of the M1 carbine, and achieved by the MP40. Furthermore, the StG 44's inline design gave it controllability even on full-auto. In short, the StG 44 provided the individual user with unparalleled firepower compared to that of all earlier handheld firearms, warranting other countries to soon embrace the assault rifle concept.
The 1st Infantry Division of Army Group South and 32nd Infantry Division of Army Group North were selected to be issued the rifle, both being refitted from heavy losses on the Eastern Front; ammunition shortages meant the 1st ID was the only division fully equipped with it. The Kar 98k was retained as a specialist weapon for sniping and launching rifle grenades, while MP 40s were used by vehicle and artillery crews and officers. The StG 44 was issued to all infantry soldiers and employed for accurate short-range rapid-fire shooting (similar to how the MP 18 was used when it went into service). The assault rifles in a squad added firepower when the machine gun had to cease fire or move. When attacking a position, Kar 98k riflemen would use grenades against it at close-range, while StG 44 riflemen would fire in rapid semi-automatic or automatic bursts to keep the defenders suppressed. The magazine follower spring had a short service life, so soldiers were ordered to load no more than 25 rounds to reduce wear of the spring. In January 1945, a magazine was introduced fitted with a fixed plug to restrict its capacity to 25 rounds. While the StG 44 was capable of fully automatic fire, German soldiers were directed to use it primarily in semi-automatic mode. Fully automatic mode was to be used only in emergencies, for short bursts of two or three rounds.
One unusual addition to the design was the "Krummlauf"; a bent barrel attachment for rifles with a periscope sighting device for shooting around corners from a safe position. It was produced in several variants: an "I" version for infantry use, a "P" version for use in tanks (to cover the dead areas in the close range around the tank, to defend against assaulting infantry), versions with 30°, 45°, 60° and 90° bends, a version for the StG 44 and one for the MG 42. Only the 30° "I" version for the StG 44 was produced in any numbers. The bent barrel attachments had very short lifespans – approx. 300 rounds for the 30° version, and 160 rounds for the 45° variant. The 30° model was able to achieve a 35×35 cm grouping at 100 m.
Some StG 44s were fitted with the Zielgerät 1229 infra-red aiming device, also known by its codename "Vampir" ("vampire"). This device consisted of a large scope, rather like modern starlight scopes, and a large infra-red lamp on top, the scope being able to pick up the infra-red that would be invisible to the naked eye. The user had to carry a transformer backpack powered by a battery fitted inside the gas mask canister. Electric cables connected the power unit with the IR reflector, with the cathode ray tube mounted on the rifle imaging IR from the spotlight. The "Vampir" had only 15 minutes of battery life, but was able to sight within 200 meters in total darkness. A conical flash hider was added to the barrel to keep the muzzle flash from blinding the shooter.
At the end of the war, Hugo Schmeisser claimed that 424,000 MP 43/MP 44/StG 44 rifles were built between June 1943 and April 1945 in four plants: 185,000 by C.G. Haenel in Suhl; 55,000 by J.P. Sauer & Sohn in Suhl; 104,000 in Erfurt; and 80,000 by Steyr-Daimler-Puch AG in Steyr, Austria. This was fewer than the 1.5 million ordered, and far fewer than the 4 million planned.
Some 822 million rounds of 7.92×33mm Kurz ammunition were produced from 1942 to 1945. At the beginning of March 1945, the troops had 273.9 million rounds, with a replenishment reserve of 69.6 million rounds on standby.
Late prototypes.
In a somewhat unrelated development, Mauser continued design work on a series of experimental weapons in an effort to produce an acceptable service-wide rifle for the short cartridge system. One of these prototypes, a product of the engineers at the Light Weapon Development Group ("Abteilung 37") at Oberndorf, was the MKb "Gerät 06 ("Maschinenkarabiner Gerät 06" or "machine carbine device 06") first appearing in 1942. This gun used a unique gas piston-delayed roller-locked action derived from the short recoil operation of the MG 42 machine gun but with a fixed barrel and gas system. It was realized that with careful attention to the mechanical ratios, the gas system could be omitted. The resultant weapon, the Gerät 06(H)", was supposedly slated for adoption by the Wehrmacht as the StG 45(M). The operating principle lived on in postwar designs from CEAM/AME, CETME, and most famously, Heckler & Koch.
Towards the end of the war, there were last-ditch efforts to develop cheap so-called "Volksgewehr" rifles in the 7.92×33mm caliber. One of these, the VG 1-5 ("Volkssturmgewehr 1-5"), used a gas-delayed blowback action based on the Barnitzke system, whereby gas bled from the barrel near the chamber created resistance to the rearward impulse of the operating parts, which ceases when the projectile leaves the muzzle, allowing the operating parts to be forced rearward by the residual pressure of the cartridge case. This principle has been used most successfully in the P7 pistol.
Post-1945.
The Sturmgewehr remained in use with the East German Nationale Volksarmee with the designation "MPi.44" until it was eventually replaced with domestic variants of the AK-47 assault rifle. The "Volkspolizei" used it until approximately 1962 when it was replaced by the PPSh-41. It was still used by other public security formations thereafter. The ammunition was manufactured there at least until 1961. Other countries to use the StG 44 after World War II included Czechoslovakia (although it was not officially adopted) and Yugoslavia, where units such as the 63rd Paratroop Battalion were equipped with it until the 1980s, when the rifles were ultimately transferred to Territorial Defense reserves or sold to friendly regimes in the Middle East and Africa. France adopted captured StG 44 for colonial Foreign Legion units.
Argentina manufactured their own trial versions of the StG 44 made by CITEFA in the late 1940s and early 1950s, but instead adopted the FN FAL in 1955, because it used the then more common and powerful 7.62×51mm NATO round, which also lacked connections with the Third Reich.
New semi-automatic civilian reproductions of the MKb 42(H), MP 43/1, and StG 44 are being manufactured in Germany today by SSD (Sport Systeme Dittrich) and distributed by HZA Kulmbach GmbH in the original 7.92×33mm Kurz chambering and accepting the standard magazines. The PTR-44 by PTR Industries was produced for a short while, but was soon discontinued due to high prices and lack of demand. A .22 rimfire copy of the StG 44 by GSG (German Sports Guns) has also been manufactured in great quantity for a lower price, but it is the only widely available reproduction of the StG. Talks have been made by HMG (Hill & Mac Gunworks) to mass-produce a StG-44 replica in different calibers, including the original 7.92×33mm Kurz, but also more modern calibers, like 7.62×39mm, 5.56×45mm NATO and .300 AAC Blackout, but these have yet to be released.
7.92mm Kurz ammunition is currently manufactured by Prvi Partizan of Serbia.
Legacy.
The StG 44 was the first assault rifle-type weapon to be accepted into widespread service and put into mass production. "The principle of this weapon — the reduction of muzzle impulse to get useful automatic fire within actual ranges of combat — was probably the most important advance in small arms since the invention of smokeless powder." The StG 44's effect on post-war arms design was wide-ranging, as made evident by Mikhail Kalashnikov's AK-47, and later Eugene Stoner's M16 and its variants. The Soviet Union was quick to adopt the assault rifle concept. The AK-47 used a similar-sized intermediate round and followed the design concept, but utilized a rotating bolt as a part of its firing action. In 1944 the US added an automatic fire capability to the M1 carbine, and issued it as the M2 carbine with 30 round magazines, fulfilling much the same function. Kits were distributed to convert M1 carbines to M2s.
The extent to which the Sturmgewehr influenced the development of the AK-47 is not clearly known. Apart from external layout similarity and the gas-operation principle, the AK-47 was not a copy of the German gun because the AK-47 used a very different mechanism. However, tens of thousands of Sturmgewehrs were captured by the Soviets and were likely provided to Kalashnikov and his team, so it is likely that he knew of it while designing the AK-47. The 7.62×39mm cartridge, however, was more directly influenced by the 7.92×33mm cartridge used in the StG 44. In July 1943, the Soviet Technical Council of the People's Commissariat for Armament (NKV) met to consider new foreign weapons firing lower-powered rounds. Two rounds that were studied were the American .30 Carbine and German 7.92 Kurz, captured from MKb 42(H) rifles undergoing troop trials. The meeting concluded that the 7.92 mm cartridge was an important development and that the Soviets needed to design a reduced-power round. The first prototype 7.62 mm M1943 round was created a month later and used the 7.92 Kurz design method of using the same caliber bullet as their standard rifle round (7.62×54mmR) in a shorter case.
After World War II, many Western countries continued using their existing full-caliber rifles. Although the 7.62×51mm NATO round adopted post-war was still a full-power cartridge, the trend towards the adoption of less powerful rounds was already under way in the West. For example, the M1 Garand had initially been developed for the .276 Pedersen (7 mm) round, a cartridge less powerful than the standard .30-06 Springfield. The U.S. Army's adoption of the M1 carbine in 1941 proved the utility of a small, handy, low-powered rifle that required little training to use effectively. Franchi of Italy-based the actions of both the LF-58 carbine and the LF-59 battle rifle on the StG-44.
United States and, later, NATO developed assault rifles along a roughly similar path by at first adding selective-fire capability in a reduced power, full-caliber cartridge. The Soviet Union lightened the AK-47 and introduced the AKM. The U.S. developed the concept of small-caliber, high-velocity (SCHV) bullets and further reduced the weight of their firearms with the introduction of the M16 (5.56 mm). The Soviet armed forces followed suit with the introduction of the SCHV AK-74 rifle (5.45 mm).
Users.
Non-state groups.
Captured StG 44 were used by Polish partisan groups during World War II, including during the Warsaw Uprising in 1944, although they were not a commonly captured weapon. Relatively large numbers of StG 44 were used post-war by Polish anti-communist resistance groups until the 1950s.
After World War II, the Soviet Union and other Eastern Bloc states supplied allied regimes and guerrilla movements with captured German arms, such as the StG 44, along with newly manufactured or repackaged 7.92×33mm ammunition. French forces discovered many in Algeria and determined the origin to be from Czechoslovakia. Examples also found their way into the hands of the Viet Cong during the Vietnam War, and the PLO. It is still used in very limited numbers by militia and insurgent forces in the Middle East as well as some countries in the Horn of Africa. StG 44s have been confiscated from militia groups by U.S. forces in Iraq.
In August 2012, the Syrian Al-Tawhid Brigade posted a video clip on their YouTube channel showing a cache of StG 44s in their possession. They claimed to have captured 5,000 StG 44 rifles and ammunition from a weapons depot in the city of Aleppo. Photos later surfaced of the rebels using them in combat. In September 2013, a photo showed a Syrian rebel with a Sturmgewehr 44 hooked up to a makeshift remote weapon station. The gun was controlled by a wired joystick, vision was provided by a video camera mounted behind a scope, and the picture was displayed on an LCD screen.
