Machine gun with a gentle name



Became a formidable means of dealing with the enemy in the air, on land and at sea

Among the various nicknames that are given to samples. weapons in the army, there is a very peaceful - "Dushka". So soldiers transformed the abbreviation DShK, belonging to a very serious large-caliber machine gun.

BIRTH OF DShK

History domestic heavy machine guns originated 27 October 1925, when the USSR Revolutionary Military Council proposed the Artillery Committee of the Red Army Artillery Directorate to 1 May 1927, to develop a machine gun caliber 12-20 mm. In the design bureau (PKB) of the First Tula Arms factories, under the leadership of I. A. Pastukhov, they created a machine gun based on the 12,7-mm cartridge "Vikkers" and the design of the Dreyze light machine gun with magazine supply. The sample received the designation P-5 - "5-linear machine gun" (i.e. X-inch caliber 0,5).

In 1928, the PKB of the Kovrov Plant No. 2 was instructed to develop a machine gun for a more powerful cartridge based on the VA Tegtyarev system machine gun, which had just been adopted, - the idea of ​​unifying machine-gun armament based on one system had already made its way. The Report of the Revolutionary Military Council of the USSR of December 1929 stated: “The adopted infantry system of the Red Army foresees the introduction of a semi-automatic self-loading rifle, self-loading pistol, submachine gun, large-caliber machine gun to combat armor, air caliper, caliper calibration, caliber gauge, caliper calibration, caliber gauge, calipers, calipers and air rifles, caliber guns, caliber guns, caliber guns, caliber guns, caliber guns, caliber guns, caliber guns, caliber guns, airborne weapons mm with a working rate of fire up to 18-20 shots ... "And yet the caliber 500 mm was chosen.

A new cartridge with an armor piercing bullet appeared in 1930, and at the end of the same year, the first prototype of a large-caliber Degtyarev machine gun with a flat disk design by A. S. Kladova with a capacity of 10 million was assembled at the workshop of the Bureau of the New Structures and Standardization. Xnumx ammo.

In February, 1931 of the year passed tests of two 12,7-mm machine guns - “Dreuze’s system for manufacturing TOZs on the Prilutsky machine and Degtyarev systems on Kolesnikov’s machine”. The commission that conducted the tests gave preference to “Degtyarev large-caliber” (DC) as being easier and simpler to manufacture. DK was commissioned, the production of small series began at the plant number 2 in Kovrov in 1932 year, but in 1933-m only 12 pieces were assembled, and in 1934-m production of Degtyarev-large-caliber was suspended.

The fact is that troop and additional ground tests of the DK in 1934 showed that the machine gun was unsuitable for combating fast-moving targets due to insufficient combat rate of fire caused by a low rate of fire, heavy and cumbersome shops. In 1935, the DK issue was completely stopped.

In 1937, G.S. Shpagin created a drum feed mechanism for a metal tape of an ingenious design, which did not require a substantial rework of the machine gun itself. In April, the 1938 machine gun with tape feed was successfully tested at the plant, 17 December - passed the test sites, and 26 February 1939, by the decision of the Committee of Defense at SNK of the USSR, adopted it as “12,7-mm heavy machine gun of the 1938 model, DSHK "(" Degtyarev-Shpagin large-caliber ").

DEVICE

Automatic machine gun operates by the removal of powder gases. The gas chamber of the closed type is equipped with a regulator with three holes of different diameters — the permutation of the regulator changed the amount of powder gases discharged to the gas piston. The fins for better cooling are made along the entire length of the barrel; a single-chamber muzzle brake of the active type is mounted on the muzzle of the barrel. The barrel was first supplied with a “parachute-shaped” muzzle brake of the active type, subsequently replaced with a flat-shaped brake.

The leading link of the automation is the slide frame. Locking the barrel is made using the lugs bolt, bred to the side. Return-combat spring is put on the gas piston rod. There are two spring dampers in the backplate, softening the impact of the bolt carrier and the bolt at the rearmost point. Dampers give the frame and bolt the initial speed of the return movement. This increased the rate of fire, but required the introduction of a counter-rebound device to prevent the frame from rebounding after impact in the extreme forward position.

The reloading handle is rigidly connected to the slide frame. The machine-gun reloading mechanism interacts with it, but the machine gunner can use it directly, for example, by inserting a cartridge cap with a cap.

The shot is made from the rear sear (from the open shutter). The trigger mechanism allows the maintenance of automatic fire only, is equipped with a flag non-automatic safety device that blocks the trigger lever and prevents the spontaneous lowering of the sear.

When the gate approaches the breech breech, it stops, and the bolt carrier continues to move forward. The drummer connected with it, with its thickened part, moves forward and spreads the lugs for the bolts, which are included in the corresponding receptions of the receiver. After locking the barrel bore, the bolt carrier continues to move forward, in the extreme forward position, the bolt bar driver strikes the striker mounted in the bolt. The reduction of the lugs and the unlocking of the bolt are made by beveling the bolt carrier when it is moved backwards.

Power supply with cartridges tape, with the left giving of a metal link tape. The tape consists of loose open links and is placed in a metal box, fastened to the installation bracket. The DShK's drum receiver is driven by the bolt carrier and, moving backward, it bumped into the fork of the swinging arm-feeder and turned it. The dog at the other end of the lever turned on the 60 of the drum, which stretched the tape. Removing the cartridge from the link tape - in the lateral direction. 12,7-mm cartridge has several options - with an armor-piercing, armor-piercing incendiary, sighting incendiary, sighting, tracer, armor-piercing incendiary tracer bullet.

For firing at ground targets, it is a folding frame sight, notched at a distance of up to 3500 m. The ZNXX model's antiaircraft ring distance sight served for firing at airplanes flying at speeds up to 1938 m. Later, the machine gun received a simplified sight of the sample 500 of the year: the firing range has decreased to 2400 m, but the target’s target flight speed has been increased to 1941 km / h. Then came the perspective anti-aircraft sight of the 1800 model of the year, which allowed firing at any course of the target, including diving or pitching, reflecting the experience of dealing with aircraft attacking at low altitudes.

Tripod in position for anti-aircraft shooting was not sufficiently stable. A special anti-aircraft gun with guidance mechanisms and a more convenient position of the sight would, of course, increase the effectiveness of anti-aircraft gunfire, but such installations did not go into the series. A number of integrated anti-aircraft installations were developed. Restrictedly used, for example, 12,7-millimeter built. The difficulties of their creation were primarily related to the power supply system - with the existing scheme, it did not allow, without significant alterations, to switch to feeding the tape from the other side.



IN MANUFACTURING AND IN FIGHT

Serial production of machine guns launched in 1939 year. The troops and the fleet of DShK began to arrive in 1940-m. Total for this year, plant number 2 them. K. O. Kirkizha produced 566 DShK, although the order plan of the People’s Commissariat of Defense for 1940 for the year was 900 machine guns plus 40 for the Navy Commissariat. The plan of orders for the 1940 year gives an idea of ​​the modifications in which the DShK was delivered to the army and the fleet: “The 12,7-mm heavy machine gun arr. 38 g. With shield, bracket for optical sight, shoulder pad, zenith. sight and with spare parts for univers. machine arr. 38 g. "," 12,7-mm machine gun arr. 38 g. On the turret mount with an MTU-2 with an annular angle sight "," 12,7-mm machine gun mod. 38 g. On sea tumbova ustan. with Kolesnikov's head with anti-aircraft sight ”,“ 12,7-mm machine gun arr. 38 without a machine ... (for tower and built installations) "," built large caliber. integrated 12,7-mm machine gun installation "," twin towers. is tired to 12,7 mm pool. arr. 38 g. With opt. scout SB-1 with mesh.

In the first half of 1941, the 234 DShK was released, although the overall plan for this year was 4000. The Navy had 830 machine guns at the beginning of the war, and in the course of the war he received 4018 units from industry and another 1146 was transferred to the fleet from the Red Army. And if the army and navy were sometimes provided with light and heavy machine guns, even beyond the state, then there was a clear lack of large-caliber weapons.

It is not by chance that in the first three months of the war, the release of large-caliber machine guns grew fivefold. The main production of DShK at factory No. 2 was duplicated in Kuibyshev, where 555 machines and accessories were transferred from Kovrov. We tried to reduce manufacturing costs: if 1941 needed 210 workers for 100 units to produce large-caliber machine guns, 1943 was required for 110 units. And if in the first six months of the war, the Armed Forces received XTC from the industry, and for the entire 1400 year, 1942 received 7400, 1943 14, 400 1944 in 14, and 800 in the first half of 1945.

The change in the share of large-caliber machine guns can be judged by the following figures: according to the staff of the December 1941, the rifle division of the Red Army had 12 large-caliber machine guns, from March 1942-xNUMX, and from December 9-1944.

The main role for large-caliber machine guns was the role of anti-aircraft installations - both in military air defense, and in the air defense system of the country, air defense of naval bases, etc. However, large-caliber machine guns were also used in the fight against ground targets. In the orders of the initial period of the war, when the German troops still widely used light Tanks in combat units, one can often find instructions on the "involvement" of heavy machine guns in the fight against tanks. Later, we also repeatedly see recommendations on the installation of DShK at the positions of anti-tank units, but already to protect them from attacks aviation enemy from low altitudes.

Fire on manpower and firing points DShK often led in urban battles. In the fight against the enemy, entrenched in fortified buildings, a large-caliber machine gun was often more effective than a machine gun of a normal caliber - due to the larger penetration effect of the bullet. This, for example, led to their use to support the actions of assault groups.

TACTICAL-TECHNICAL CHARACTERISTICS OF DShK (sample 1938)

Cartridge 12,7x108 DShK
Machine gun body weight without kg 33,4 tape
Mass machine gun with a ribbon on the machine Kolesnikov (without a shield) 148 kg
Body length machine gun 1626 mm
Barrel length 1070 mm
Initial bullet speed 850-870 m / s
The muzzle energy of a bullet 18 785-19 679 j
Firing rate 550-600 rds / min
Fighting rate of fire 80-125 rds / min
Sighting range 3500 m
Effective range 1800-2000 m
Shelling zone height 1800 m
The thickness of the pierced armor 15-16 mm at a distance 500 m
Power system metal tape on 50 cartridges

DShK played the role and tank machine gun. In 1939, it was the main armament of light tanks T-40 and T-40С, in 1942-m it was placed on light armored vehicles BA-64Д. In the 1944, the 12,7-mm turret anti-aircraft gun appeared on the IS-2 heavy tank. Heavy self-propelled guns of the ISU series were equipped with DShK turrets for firing at air and ground targets.

We must admit that the production of DShK in the conditions of war could not be deployed in accordance with the need. For comparison: in the United States over the same period, more than 400 thousands of 12,7-mm M2 machine guns of the Browning system of several modifications were launched. Therefore, when organizing supplies under Lend-Lease, we paid considerable attention to large-caliber machine guns and machine-gun installations.

By the way, the German army, which did not have regular large-caliber machine guns, readily used captured DShKs, to which the Wehrmacht Army Armaments Administration assigned the designation MG.286 (r). Also a confession.


MODERNIZATION

At the end of the Great Patriotic War, K. I. Sokolov and A. K. Norov conducted a substantial modernization of the DShK. First of all, she touched the power supply mechanism - a slider came to replace the drum receiver, which simplified the change of the tape feed direction from left to right. In addition, the manufacturability, survivability and reliability in work have improved, and the barrel mount has changed.

The first 250 modernized machine guns were released in February 1945-th at the plant in Saratov (there, as in Kuybyshev, back in 1941-m, part of the production of the Tula machine-building plant was evacuated). In 1946, the machine gun is adopted under the designation "12,7-mm machine gun rev.1938 / 46 of the GDQM" (despite the replacement of the receiver, the name Shpagin in the brand of machine gun was rightly preserved).

DShKM immediately became a tank anti-aircraft machine gun (DShKMT) - they were equipped with a series of tanks IC, T-54 / 55, T-62, BTR-50PA, upgraded ISU-122 and ISTU-152, special machines. He is one of the most widespread large-caliber machine guns in the world, along with his long-standing rival, the American 12,7-mm Browning, an 2-N American machine gun. DShKM is in service with more than 40 armies in the world. In addition to the USSR, it was produced in Czechoslovakia (DSK vz.54), Romania, China (Type 54 and modernized Type 59), Pakistan (Chinese version), Iran, Iraq, Thailand.

    At the end of the 80-x had a chance to shoot from him on the "educational air target," as such, acted lighting flare on a parachute. It turns out not so easy to get into, even though not far away. The rocket swings and falls at an angle. The most optimal mode of fire-short bursts of 2-3 shot, the rate of fire is not relatively high. If the queue is longer than the 5 shots, delays appear and dispersion increases.

          In our army, too, it still exists, with all the disadvantages of the DShK (large weight, low rate of fire, not very convenient loading), it has a universal machine, unlike NSV. Which allows firing at both ground and air targets. About a year ago, I observed the deployment of the C-300P battalion in the “field,” a cover from low-altitude attacks was carried out by MANPADS and DShK in the back of a KAMAZ vehicle.

    Great machine gun! In Afghanistan, in my company there were two types of large-caliber: captured Chinese DShK and easel 14,5 mm PKM. I had to shoot from both. The preference was given to DShK - simple, unpretentious, trouble-free. These two machine guns stood at outposts in the mountains. I remember at the “Fedotov” post for the DShK the lubrication was over and at the next cleaning after firing, the fat was still frozen from the stew and it lubricated all the moving parts in the receiver and the barrel. It worked like a clock. But after the battle, over the entire skyscraper, the smell of beef skewers floated. A pin broke on the bolt frame, cut the exact same one with an ax out of a nail-weave, and .. continued to shoot for a sweet soul. And RMB exhausted his soul. Everything was a little clogged: delays, poking, and platoon did not get. Of course the caliber of the go, the darlings immediately ran away as soon as they started shooting. And with the DShK, a whip is a kilometer long. Whom you want and how you want to bread. The beauty!

      With proper maintenance, any machine will be healthy. The DShK, of course, is no longer an ice - but it has no equal in reliability. It is heavy with the machine, you cannot drop more than one box of 50 rounds without overheating the barrel - but it’s VERY effective. legs tear off. No wonder they are still used as mobile firing points in the east.
      And the easel 14,5 mm PKM is a wonderful hybrid of PKM and KPVT, the best machine gun of Afghanistan.

          It may be a product of the First World War, but the Americans did not leave that they were not doing their job successfully for almost a century. And not only them. And this is a pretty accurate weapon apparently. I love the weapons created in the USSR and Russia as a whole, but during the same time, the Soviet and then the Russian army changed three heavy machine guns. I think that speaks enough for itself.

        Yes, yes it is his infantry version of the KPVT, on the machine. Three bags of stones were piled on each bipod so that it would not wind up on the recoil. Wow and capricious, but the caliber is solid, but with the MDZ cartridges it’s generally dead. The dushki in the current stones fidgeted so much, but how to concentrate the fire, at once with your feet in your hands and run.

    Unfortunately, during VOV, the DShK did not become an infantry weapon, basically all the machine guns went to the fleet as if they were an “ersatz” of the MZA and therefore could not show themselves, the situation was similar in air defense, where DShKs were used as a defensive weapon of batteries. Only in December 44 saturation of reconnaissance units with these weapons began (as machine arms). And in 45g, thanks to tankers and self-propelled guns, the machine gun really "realized" in urban battles and in densely built-up areas, being the most effective a means (in those conditions) of the fight against the "Fausniki". But time does not stand still, now in the RF Armed Forces, the DShK is more likely a "museum exhibit" if you meet it. It was replaced by the "Cliff" more "accurate" machine, but the returns are still too big (in my opinion). “Cords” are now arriving — let's hope they become worthy receivers devoid of the shortcomings of the “ancestors”.

    DShK is of course a very good weapon, superior in accuracy to its NSV heir, but certainly not without flaws. One disassembly, using a hammer means a lot ... in the field, and even more so in combat, this may well become a problem. But as a weapon he is of course "GOOD" ...

        NSV-12,7 was much lighter than its predecessor - the mass of 25 kg for a machine gun of this caliber with existing technologies is still the limit.

          The truth is yours. But you speak the words of the marketer and not a word about the combat use.

            So the combat use is the same - the defeat of technology and manpower of the enemy. What CORD is very good at.
            Z.Y. These are not the words of a marketer, but an engineer. You see, since 1932, technology and technological capabilities have changed somewhat. Accordingly, it became possible to make it simpler, easier and cheaper, without loss of performance.

              Provide feedback on the NSV in battle. Let the storming of Grozny be in December 1994, for many have seen and will not let lie.

                  You did not answer the question. Give feedback, and not only positive. Your answer is that it worked fine for me ... Tell me WHERE WHERE it worked for YOU "quite normally". In what combat conditions, in what weather. So? Drum roll, now anomalocaris user will share something mysterious in the work of the NSW ...

                    Sucks being stupid, baby. Now share your experience where the NSW worked abnormally?
                    And also share your impressions of dragging to the 4th floor of the DShK with the machine tool and the NSV with the machine tool.
