On February 26, 1939, by decree of the Defense Committee under the Council of People's Commissars of the USSR, a 12.7-mm heavy machine gun of the 1938 model DShK ("Degtyarev-Shpagina large-caliber") of the V. A. Degtyarev system with a drum receiver of the G. S. system was adopted for service. Shpagina. The machine gun was adopted on a universal machine of the I.N. system. Kolesnikov with detachable wheel travel and folding tripod. During the Great Patriotic War The DShK machine gun was used to combat air targets, lightly armored enemy vehicles, and enemy personnel at long and medium ranges, as weapons for tanks and self-propelled guns. At the end of the Great Patriotic War, designers K.I. Sokolov and A.K. Norov carried out a significant modernization of the heavy machine gun. First of all, the power mechanism was changed - the drum receiver was replaced with a slider one. In addition, the manufacturability of the weapon has been improved, the mounting of the machine gun barrel has been changed, and a number of measures have been taken to increase survivability. The reliability of the system has increased. The first 250 modernized machine guns were produced in February 1945 at the plant in Saratov. In 1946, the machine gun was put into service under the designation “12.7-mm machine gun mod. 1938/46, DShKM." The DShKM immediately became a tank anti-aircraft machine gun: it was installed on tanks of the IS series, T-54/55, T-62, on the BTR-50PA, modernized ISU-122 and ISU-152, and special vehicles on a tank chassis.
Because the differences are 12.7 mm heavy machine gun arr. 1938, DShK and a modernized machine gun mod. 1938/46 DShKM consist mainly in the design of the feed mechanism, let's look at these machine guns together.
The machine gun is automatic and operates by removing powder gases through a transverse hole in the barrel wall, with a long stroke of the gas piston. Gas chamber closed type reinforced under the barrel and equipped with a pipe regulator with three holes. The entire length of the barrel has transverse ribbing for better cooling; a single-chamber active-type muzzle brake is attached to the muzzle of the barrel. The barrel bore is locked by moving the bolt lugs to the sides. The DShK barrel was equipped muzzle brake active type, which was later replaced by a flat brake, also of the active type (such a muzzle brake was also used on the DShK, and became the main one for tank modifications).
The leading element of the automation is the bolt frame. A gas piston rod is screwed into the bolt frame at the front, and a firing pin is mounted on a stand at the rear. When the bolt approaches the breech of the barrel, the bolt stops, and the bolt frame continues to move forward, the firing pin rigidly connected to it with its thickened part moves forward relative to the bolt and spreads the bolt lugs, which fit into the corresponding recesses of the receiver. The lugs are brought together and the bolt is unlocked by bevels of the figured socket of the bolt frame as it moves backwards. Removal of the spent cartridge case is ensured by the bolt ejector; the cartridge case is removed from the weapon downwards, through the window of the bolt frame, using a spring-loaded rod reflector mounted at the top of the bolt. The return spring is placed on the gas piston rod and covered with a tubular casing. The buttplate contains two spring shock absorbers that soften the impact of the bolt carrier and bolt at the rearmost point. In addition, shock absorbers give the frame and bolt initial speed return movement, thereby increasing the rate of fire. The reloading handle, located at the bottom right, is rigidly connected to the bolt frame and is small in size. The reloading mechanism of the machine gun mount interacts with the reloading handle, but the machine gunner can directly use the handle, for example, by inserting a cartridge into it with the bottom of the cartridge case.
The shot is fired with the shutter open. The trigger mechanism allows only automatic fire. It is activated by a trigger lever hinged on the buttplate of the machine gun. The trigger mechanism is assembled in a separate housing and is equipped with a non-automatic safety lever that blocks the trigger lever (front position of the flag) and prevents spontaneous lowering of the sear.
The impact mechanism is powered by a return spring. After locking the barrel bore, the bolt frame continues to move forward, in the extreme forward position it hits the clutch, and the firing pin hits the firing pin mounted in the bolt. The sequence of operations of spreading the lugs and striking the firing pin eliminates the possibility of firing when the barrel bore is not fully locked. To prevent the bolt frame from rebounding after an impact in the extreme forward position, a “delay” is mounted in it, including two springs, a bend and a roller.

DShKM machine gun incompletely disassembled: 1 - barrel with gas chamber, front sight and muzzle brake; 2 - bolt frame with gas piston; 3 - shutter; 4 - combat stops; 5 - drummer; 6 - wedge; 7 - butt plate with buffer; 8 - trigger housing; 9 - cover and base of the receiver and feed drive lever; 10 - receiver.

The cartridges are fed by a belt feed, with a left-hand feed of a metal link belt. The tape consists of open links and is placed in a metal box mounted on the installation bracket. The visor of the box serves as the tape feed tray. The DShK drum receiver was driven by the bolt handle, moving backward, it bumped into the fork of the swinging feed lever and turned it. The dog at the other end of the lever rotated the drum 60°, which pulled the tape. Removing the cartridge from the belt link - in the lateral direction. In the DShKM machine gun, the slider-type receiver is mounted on top of the receiver. The slider with the feed fingers is driven by a bell crank rotating in a horizontal plane. The crank arm, in turn, is driven by a rocker arm with a fork at the end. The latter, as in the DShK, is driven by the bolt handle.
By flipping the slider crank, you can change the direction of the belt feed from left to right.
The 12.7 mm cartridge has several options: with an armor-piercing bullet, armor-piercing incendiary, sighting-incendiary, sighting, tracer, armor-piercing incendiary tracer (used against air targets). The sleeve does not have a protruding rim, which made it possible to use direct feeding of the cartridge from the tape.
For shooting at ground targets, a folding frame sight is used, mounted on a base on top of the receiver. The sight has worm mechanisms for installing the rear sight and introducing lateral corrections, the frame is equipped with 35 divisions (up to 3500 m in 100) and is tilted to the left to compensate for bullet derivation. The pin front sight with a safety device is placed on a high base in the muzzle of the barrel. When firing at ground targets, the dispersion diameter at a distance of 100 m was 200 mm. The DShKM machine gun is equipped with a collimator anti-aircraft sight, which facilitates aiming at a high-speed target and allows you to see the aiming mark and the target with equal clarity. The DShKM, installed on tanks as an anti-aircraft weapon, was equipped collimator sight K-10T. The optical system of the sight formed at the output an image of the target and an aiming reticle projected onto it with rings for shooting with lead and protractor divisions.

The DShK machine gun entered the Workers' and Peasants' Red Army back in February 1939, but despite the seven decades that have passed since then, it is still present among the staff heavy weapons in many armies. In this article we will briefly outline the history and design features of this outstanding example domestic design thought.

A product of the First World War. Initially, they were tasked with fighting the then weakly armored tanks, aircraft and infantry in light shelters. It was precisely these opportunities that the Red Army command craved to receive from the new domestic machine gun, issuing technical specifications for it to the designers. The DShK machine gun was born for ten whole years, one might say, when the most advanced and powerful domestic cartridge for its time, 12.7 x 108, was invented, which, by the way, is still actively used in modern rifle systems. However, for a long time Degtyarev was unable to create something acceptable for the army. The main disadvantage of the DK (Degtyarev large-caliber) model of 1930 was the drum magazine for thirty rounds and the low rate of fire, which did not allow the machine gun to be effectively used as an anti-aircraft gun. Only the involvement of another outstanding designer, G.S. Shpagin, in the development, made it possible to solve the problem. A drum-type chamber was installed on the Degtyarev machine gun for belt ammunition designed by Shpagin, as a result of which the machine gun acquired a very decent rate of fire of 600 rounds per minute, belt feeding and the now well-known name “DShK Machine Gun”. Since 1939, he entered combat units and since then has participated and is participating in all armed conflicts in the world. It is currently in service with forty armies. Produced by China, Iran, Pakistan and some other countries.

DShK heavy machine gun: design and modifications

The automatic machine gun operates on the common principle of removing expanding powder gases. The gas exhaust chamber is located under the barrel. Locking occurs with the help of two combat larvae, which cling to recesses machined in the opposite walls of the receiver. The DShK machine gun can only fire automatically; the barrel has a non-removable barrel and is air-cooled. The cartridge belt is fed from the left side to the drum, which has six open chambers. The latter, rotating, feeds the tape and at the same time removes cartridges from it. In 1946, changes were made to the design that affected the steel grades used, production technology and cartridge feeding device. The “drum” was abandoned and a simpler slider mechanism was used, which made it possible to use new cartridge belts, on both sides, and was lighter and more technologically advanced. The improved machine gun was called DShKM.

Conclusion

There are only two truly famous 12 mm machine guns in the world. These are the DShK and M2 machine guns, and the domestic machine gun, due to its more powerful cartridge and heavy bullet, is superior to its American counterpart. Until now, DShK fire is considered highly effective and terrifies the enemy.

The DShK heavy machine gun was developed 78 years ago. And if in our army the “Dashka” at the combat post was long ago replaced by “Utes” and even more modern ones, then in many “hot spots” of the planet the machine gun continues to fight. What the local “lefties” and “Kulibins” are doing with the DShK is worthy of a separate description.

A little history. An easel machine gun chambered for 12.7x108 mm, called DShK (Degtyarev-Shpagin large-caliber), was developed on the basis of the DK machine gun and put into service in February 1939. The weapon was used both on land and at sea: on ships, armored vehicles, the T-40 amphibious tank, the T-60 tank (experimental anti-aircraft gun with two twin DShK in an open turret), on self-propelled guns ISU-122, ISU-152, tanks IS-2, IS-3 (as an anti-aircraft gun), on armored trains and so on.

In the infantry version, on a wheeled machine with an armored shield, the machine gun was intended to fight infantry, light armored vehicles and enemy firing points.

The DShK also existed in various anti-aircraft versions. The photo shows a built anti-aircraft machine gun installation near the Metropol restaurant in Moscow.

After the war, “dashkas” were equipped with many Soviet tanks (T-54, T-55, T-62, IS-3, T-10), self-propelled guns (ASU-85), armored personnel carriers BTR-152, BTR-40. Later they began to be replaced new machine gun NSV "Utes", and in lately- “Cord.”

Now DShK in Russia can only be found in museums and mobile warehouses. At the same time, his American “classmate” - Browning M2 - is even older than his Soviet “colleague”. Subject to various upgrades, it has served and continues to serve in the US Army since 1932.

Naturally, the Soviet DShK was widely exported - both together with armored vehicles and separately - to many countries of the socialist camp, Asia and Africa. And its licensed or not so licensed release was established by China, Iran, Pakistan, Czechoslovakia, Romania, Yugoslavia and even Sudan.

Therefore, you can meet a “Dashka” in almost any theater of military operations of the 21st century. Despite the fact that the machine gun is quite heavy, it is simple, reliable, lethal, and getting cartridges for it is not difficult.

Most often, DShKs are installed on all-wheel drive pickup trucks and jeeps by militants of various paramilitary formations. The result is carts of modern times - the so-called “teknikals”. They first began to be used en masse in the war between Libya and Chad in 1987. The conflict was nicknamed the "Toyota War" due to the prevalence of this brand of military vehicles among Chadian military vehicles.

Then Chadian army units in several hundred SUVs equipped with heavy machine guns and Milan anti-tank systems were able to inflict a number of painful blows on the clumsy Libyan group.

IN civil war, which began in Libya in 2011, “technicals” became the main weapons and means of transportation of the “rebels”. Often they installed a famous DShK veteran.

The desert plains of Syria and Iraq also contributed to the fact that "teknikals" became a kind of business card militants of ISIS, Al-Nusra and other “armed opposition” groups.

But government forces also use it. This photo shows an epic combination of 14.5 mm KPV and 12.7 DShK in a twin.

In Ukraine they did not lag behind the general “fashion”.

DShKs are often used to enhance the armament of light armored vehicles. Sometimes you get interesting combinations like this: an American M113 armored personnel carrier with a DShK instead of the standard Browning M2 in Yemen.

And in Syrian Kurdistan, one of the Kurdish YPG units installed a DShK on an MTLB armored tractor.

The Ukrainian Armed Forces also arm the MTLB in a similar way.

The Ukrainian army, in principle, has a certain need for modern machine guns, including large-caliber ones. Therefore, old DShKs were removed from warehouses.

The task to create the first Soviet heavy machine gun, intended primarily to combat aircraft at altitudes of up to 1500 meters, was issued by that time to the already very experienced and well-known gunsmith Degtyarev in 1929. Less than a year later, Degtyarev presented his 12.7mm machine gun for testing, and in 1932, small-scale production of the machine gun began under the designation DK (Degtyarev, Large-caliber). In general, the DK was similar in design to the DP-27 light machine gun, and was fed from detachable drum magazines with 30 rounds of ammunition, mounted on top of the machine gun. The disadvantages of such a power supply scheme (bulky and heavy weight magazines, low practical rate of fire) forced to stop production of the recreation center in 1935 and start improving it. By 1938, designer Shpagin developed a belt feed module for the recreation center, and in 1939 the improved machine gun was adopted by the Red Army under the designation “12.7mm heavy machine gun Degtyarev-Shpagin model 1938 - DShK.” Mass release DShK was started in 1940-41. They were used as anti-aircraft weapons, as infantry support weapons, and installed on armored vehicles and small ships (including torpedo boats). Based on the experience of the war, in 1946 the machine gun was modernized (the design of the belt feed unit and barrel mount were changed), and the machine gun was adopted under the designation DShKM.
The DShKM has been or is in service with over 40 armies around the world and is produced in China (“type 54”), Pakistan, Iran and some other countries. The DShKM machine gun was used as an anti-aircraft gun Soviet tanks post-war period (T-55, T-62) and on armored vehicles (BTR-155). Currently, in the Russian Armed Forces, the DShK and DShKM machine guns have been almost completely replaced by the Utes and Kord large-caliber machine guns, which are more advanced and modern.

The DShK heavy machine gun is an automatic weapon built on the gas exhaust principle. The barrel is locked by two combat larvae, hinged on the bolt, through recesses in the side walls of the receiver. The fire mode is automatic only, the barrel is non-removable, finned for better cooling, and equipped with a muzzle brake. The feed is carried out from a non-scattered metal tape; the tape is fed from the left side of the machine gun. In DShK, the tape feeder was made in the form of a drum with six open chambers. As the drum rotated, it fed the tape and at the same time removed cartridges from it (the tape had open links). After the chamber of the drum with the cartridge arrived in the lower position, the cartridge was fed into the chamber by the bolt. The tape feeder was driven using a lever located on the right side, which swung in a vertical plane when its lower part was acted upon by the loading handle, rigidly connected to the bolt frame. In the DShKM machine gun, the drum mechanism has been replaced with a more compact slider mechanism, also driven by a similar lever connected to the loading handle. The cartridge was removed from the belt downwards and then fed directly into the chamber.
Spring buffers of the bolt and bolt frame are mounted in the buttplate of the receiver. The fire was fired from the rear sear (from the open bolt), two handles on the butt plate and evaporated triggers were used to control the fire. The sight was framed; the machine also had mounts for an anti-aircraft foreshortening sight.

The machine gun was used from a universal machine gun of the Kolesnikov system. The machine was equipped with removable wheels and a steel shield, and when using the machine gun as an anti-aircraft wheel, the shield was removed and the rear support was spread apart to form a tripod. In addition, the anti-aircraft machine gun was equipped with special shoulder rests. The main disadvantage of this machine was its high weight, which limited the mobility of the machine gun. In addition to the machine gun, the machine gun was used in turret installations, on remote-controlled anti-aircraft installations, and on ship pedestal installations.

With the start of work on a machine gun with a caliber of 12-20 millimeters in 1925, they decided to create it based on light machine gun magazine-fed to reduce the mass of the machine gun being created. Work began at the design bureau of the Tula Arms Plant on the basis of the 12.7-mm Vickers cartridge and on the basis of the German Dreyse (P-5) machine gun. The design bureau of the Kovrov plant was developing a machine gun based on the Degtyarev light machine gun for more powerful cartridges. A new 12.7-mm cartridge with an armor-piercing bullet was created in 1930, and at the end of the year the first experimental large-caliber Degtyarev machine gun with a Kladov disc magazine with a capacity of 30 rounds was assembled. In February 1931, after testing, preference was given to the DK (“Degtyarev large-caliber”) as easier to manufacture and lighter. The recreation center was put into service; in 1932, a small series was produced at the plant named after. Kirkizha (Kovrov), however, in 1933 only 12 machine guns were produced.

Experimental installation of the DShK machine gun

Military tests did not live up to expectations. In 1935, production of the Degtyarev heavy machine gun was stopped. By this time, a version of the DAK-32 had been created that had a Shpagin receiver, but tests in 1932-1933 showed the need to refine the system. Shpagin remade his version in 1937. A drum feed mechanism was created that did not require significant changes to the machine gun system. The belt-fed machine gun passed field tests on December 17, 1938. On February 26 of the following year, by resolution of the Defense Committee, they adopted it for service under the designation “12.7-mm heavy machine gun mod. 1938 DShK (Degtyarev-Shpagina large-caliber)” which was installed on the Kolesnikov universal machine. Work was also carried out on the DShK aircraft installation, but it soon became clear that a special large-caliber aircraft machine gun was needed.

The automatic operation of the machine gun was carried out due to the removal of powder gases. A closed gas chamber was located under the barrel and was equipped with a pipe regulator. The barrel had fins along its entire length. The muzzle was equipped with a single-chamber active-type muzzle brake. By moving the bolt lugs to the sides, the barrel bore was locked. The ejector and reflector were assembled in the gate. A pair of spring shock absorbers of the butt plate served to soften the impact of the moving system and give it an initial rolling impulse. A return spring, mounted on the gas piston rod, activated the impact mechanism. The trigger lever was blocked by a safety lever mounted on the buttplate (setting the safety to the front position).

Feeding – belt, feeding – from the left side. The loose tape, which has semi-closed links, was placed in a special metal box attached to the left side of the machine bracket. The bolt carrier handle activated the DShK drum receiver: while moving backward, the handle bumped into the fork of the swinging feed lever and turned it. A pawl located at the other end of the lever rotated the drum 60 degrees, and the drum, in turn, pulled the tape. There were four cartridges in the drum at a time. As the drum rotated, the cartridge was gradually squeezed out of the belt link and fed into the receiving window of the receiver. The shutter moving forward caught it.

The folding frame sight, used for firing at ground targets, had a notch up to 3.5 thousand meters in increments of 100 m. The machine gun’s markings included the manufacturer’s mark, year of manufacture, serial number (series designation - two-letter, serial number of the machine gun) . The mark was placed in front of the butt plate on top of the receiver.

During operation with the DShK, three types of anti-aircraft sights were used. The ring distance sight of the 1938 model was intended to destroy air targets flying at speeds of up to 500 km/h and at a distance of up to 2.4 thousand meters. The sight of the 1941 model was simplified, the range was reduced to 1.8 thousand meters, but the possible speed of the destroyed target increased (along the “imaginary” ring it could be 625 kilometers per hour). The sight of the 1943 model was of the foreshortening type and was much easier to use, but allowed firing at various target courses, including pitching or diving.

Heavy machine gun DShKM 12.7 model 1946

The universal Kolesnikov machine of the 1938 model was equipped with its own charging handle, had a removable shoulder pad, a cartridge box bracket, and a rod-type vertical aiming mechanism. Fire at ground targets was carried out from a wheeled vehicle, with the legs folded. To fire at air targets, the wheel drive was separated, and the machine was laid out in the form of a tripod.

The 12.7 mm cartridge could have an armor-piercing bullet (B-30) of the 1930 model, an armor-piercing incendiary bullet (B-32) of the 1932 model, sighting and incendiary (PZ), tracer (T), sighting (P), against anti-aircraft guns targets, an armor-piercing incendiary tracer bullet (BZT) of the 1941 model was used. The armor penetration of the B-32 bullet was 20 millimeters normal from 100 meters and 15 millimeters from 500 meters. The BS-41 bullet, whose core was made of tungsten carbide, was capable of penetrating 20 mm armor plate at an angle of 20 degrees from a range of 750 meters. The dispersion diameter when firing at ground targets was 200 millimeters at a distance of 100 meters.

The machine gun began to enter service with the troops in 1940. In total, in 1940, plant No. 2 in Kovrov produced 566 DShKs. In the first half of 1941 - 234 machine guns (in total, in 1941, with a plan of 4 thousand DShK, about 1.6 thousand were received). In total, as of June 22, 1941, the Red Army units had about 2.2 thousand heavy machine guns.

From the first days of the Second World War, the DShK machine gun proved itself to be an excellent anti-aircraft weapon. So, for example, on July 14, 1941, Western Front in the Yartsevo area, a platoon of three machine guns shot down three German bombers; in August, near Leningrad, in the Krasnogvardeisky area, the Second Anti-Aircraft Machine Gun Battalion destroyed 33 enemy aircraft. However, the number of 12.7-mm machine gun mounts was clearly not enough, especially considering the enemy's significant air superiority. As of September 10, 1941, there were 394 of them: in the Oryol zone air defense– 9, Kharkov – 66, Moscow – 112, on the South-Western Front – 72, Southern – 58, North-Western – 37, Western – 27, Karelian – 13.

Since June 1942, the staff of the anti-aircraft artillery regiment of the army included a DShK company, which was armed with 8 machine guns, and since February 1943 their number increased to 16 units. The anti-aircraft artillery divisions of the RVGK (Zenad), formed since November 42, included one such company per anti-aircraft small-caliber artillery regiment. Since the spring of 1943, the number of DShKs in Zenad decreased to 52 units, and according to the updated state of the 44th in the spring, Zenad had 48 DShKs and 88 guns. In 1943, the cavalry, mechanized and tank corps regiments of small-caliber anti-aircraft artillery were introduced (16 DShK and 16 guns).

Typically, anti-aircraft DShKs were used by platoons, often included in medium-caliber anti-aircraft batteries, using them to provide cover from air attacks from low altitudes. Anti-aircraft machine gun companies armed with 18 DShKs were brought into service at the beginning of 1944 rifle divisions. Throughout the war, losses of heavy machine guns amounted to about 10 thousand units, that is, 21% of the resource. This was the smallest percentage of losses in the entire system. small arms, however, it is comparable to losses in anti-aircraft artillery. This already speaks about the role and place of heavy machine guns.

In 1941, as German troops approached Moscow, backup factories were identified in case Factory No. 2 stopped producing weapons. The production of DShK was carried out in the city of Kuibyshev, where 555 devices and machines were transferred from Kovrov. As a result, during the war, the main production took place in Kovrov, and “duplicate” production took place in Kuibyshev.

In addition to easel ones, self-propelled units with DShK were used - mainly M-1 pickups or GAZ-AA trucks with a DShK machine gun installed in the body in the anti-aircraft position on the machine. “Anti-aircraft” light tanks on the T-60 and T-70 chassis did not advance further than prototypes. The same fate befell the integrated installations (although it should be noted that the built-in 12.7-mm anti-aircraft installations were used to a limited extent - for example, they served in the air defense of Moscow). The failures of the installations were associated, first of all, with the power system, which did not allow changing the direction of feed of the tape. But the Red Army successfully used 12.7-mm American quad mounts of the M-17 type based on the M2NV Browning machine gun.

The “anti-tank” role of the DShK machine gun, which received the nickname “Dushka,” was insignificant. The machine gun was used to a limited extent against light armored vehicles. But the DShK became a tank weapon - it was the main armament of the T-40 (amphibious tank), BA-64D (light armored car), in 1944 a 12.7-mm anti-aircraft turret was installed on heavy tank IS-2, and later on heavy self-propelled guns. Anti-aircraft armored trains were armed with DShK machine guns on tripods or stands (during the war, up to 200 armored trains operated in the air defense forces). The DShK with a shield and a folded machine could be dropped to partisans or landing forces in a UPD-MM parachute bag.

The fleet began receiving DShKs in 1940 (at the beginning of the Second World War there were 830 of them). During the war, industry transferred 4,018 DShKs to the fleet, and another 1,146 were transferred from the army. In the navy, anti-aircraft DShKs were installed on all types of ships, including mobilized fishing and transport ships. They were used on twin single pedestals, turrets, and turrets. Pedestal, rack and turret (coaxial) installations for DShK machine guns, adopted for service navy, developed by I.S. Leshchinsky, designer of plant No. 2. The pedestal installation allowed for all-round firing, vertical guidance angles ranged from -34 to +85 degrees. In 1939 A.I. Ivashutich, another Kovrov designer, developed a twin pedestal installation, and the later appeared DShKM-2 gave all-round fire. Vertical guidance angles ranged from -10 to +85 degrees. In 1945, the 2M-1 twin deck-mounted installation, which had a ring sight, was put into service. The DShKM-2B twin turret installation, created at TsKB-19 in 1943, and the ShB-K sight made it possible to conduct all-round fire at vertical guidance angles from -10 to +82 degrees.

For boats of various classes, open turret twin installations MSTU, MTU-2 and 2-UK were created with pointing angles from -10 to +85 degrees. The “naval” machine guns themselves differed from the base model. For example, in the turret version, a frame sight was not used (only a ring sight with a weather vane front sight was used), the bolt handle was lengthened, and the hook for the cartridge box was changed. The differences between machine guns for coaxial installations were the design of the butt plate with the frame handle and trigger lever, the absence of sights, and fire control.

The German army, which did not have a standard heavy machine gun, willingly used captured DShKs, which were designated MG.286(r).

At the end of the Second World War, Sokolov and Korov carried out a significant modernization of the DShK. The changes primarily affected the food system. In 1946 modernized machine gun under the DShKM brand was put into service. The reliability of the system has increased - if on the DShK according to the specifications 0.8% of delays during firing were allowed, then on the DShKM this figure was already 0.36%. The DShKM machine gun has become one of the most widely used in the world.
