The role of large-caliber machine guns in the modern realities of armed conflict is increasing, which largely determines their creation in many leading countries, including Russia. At the same time, an analysis of the characteristics of Russian heavy machine guns in comparison with other most well-known and common foreign counterparts demonstrates that Russian-made machine guns outperform foreign ones in their weight and size characteristics, reliability of operation and rate of fire. First of all it concerns the newest large-caliber machine gun "Kord".
The Kord heavy machine gun is designed to destroy enemy personnel, combat fire weapons and lightly armored targets at a range of up to 2,000 meters, as well as hitting targets in the air at inclined distances of up to 1,500 meters. The Kord machinegun has a 12.7 caliber specifications. The main purpose of its creation was the need to replace in the army machine guns "cliff".
History of creation
The main reasons for replacing the gunner NSV 12.7 "Rock" after almost 20 years of its use on the machine gun "Kord" were:
- identified certain shortcomings of the cliff, in particular, the demonstrated accuracy of shooting did not meet modern requirements;
- after the collapse of the USSR, the production of machine guns NSV remained in the territory of Kazakhstan and Ukraine.
Work on the modernization of the machine gun "cliff" in the 1990s engaged in the SKB plant them. Degtyarev in Kovrov. This is Yu.M. gunsmiths. Bogdanov, V.I. Zhirohin, N.M. Obidin, A.A. Namitulin.
When creating a new weapon, gunsmith designers successfully solved 3 most important problems at once:
- increase the stability of the machine gun and reduce the recoil energy, which allowed us to create an infantry version of the Kord machine gun mounted on the bipod;
- to ensure the process of independence of actions of automation and mechanisms of the barrel, which positively affects the characteristics of firing accuracy and eliminates resonant oscillations of the machine gun;
- significantly increase the survivability of the barrel of the machine gun, so that the heavy machine gun could be completed with only one barrel.
The new machine gun was called the Kord, as well as an upgraded locking system, a new barrel with a muzzle brake-flame arrester.
Purposeful work on the creation of a new machine gun was completed in 1997, and in the following 1998 they adopted the Russian heavy machine gun "Kord" in the main 3 versions:
- tank - 6P49;
- infantry - 6P50;
- with left-handed power - 6P51.
The base version was a tank "Kord", equipped with electroshoot. It is installed on the tower of the T-90 tank. Infantry version is designed for installation on machines, as well as installations of machine-gun systems. The left-handed version is used for sharing with right-handed machine guns - in paired sea-based and land-based installations.
Performance characteristics
Machine gun "Kord" demonstrates the following mph:
- Caliber - 12.7 mm.
- The rate of fire - 600 shots per minute.
- The initial speed of the bullet is 820 - 860 m / s.
- Sighting range - 2000 m.
- The mass of the barrel - 9.25 kg.
- Machine gun body weight - 25.5 kg.
- The curb weight is 11.1 kg.
- The weight of the tape with 50 rounds is 7.7 kg.
- The angle of horizontal pickup of weapons on the bipod is ± 15 degrees.
- The accuracy of combat at a distance of 100 m is <300 mm.
- Technical resource - 10,000 shots.
- Penetration on 100 meters - up to 20 mm.
Ammunition
Ammunition includes 12.7-mm cartridges:
1. with armor-piercing incendiary bullets;
2. with incendiary tracer bullets.
In the "ZiD" main ammunition declared B-32 and BZT-44. At the same time, the Kord heavy machine gun can also use ammunition:
- incendiary instant action of MDZ;
- The armor-piercing incendiary BS-41, which has a bullet with a special tungsten core, it significantly increases the penetration rate.
The B-32 bullet can pierce 20 mm steel from 100 m, at the same time the bullet of the BS-41 cartridges will do the same from a distance of 750 m. A metal link is used to equip the tape.
Design features
- The kind of fire is performed in bursts. Single firing are jerky pressing the trigger lever.
- Open sight, mechanical, 2000 m. It is possible to install night and optical sights. For this, the light machine gun was supplied with a bracket for setting night and optical sights.
- Right-hand or left-handed feed tape (left-sided design is used in twin machine gun installations).
- The machine gun is built on the basis of vapor automation. The barrel is locked with a wedge gate. In the trigger mechanism is a fuse against accidental shots. It can be controlled manually (easel version - from the trigger), and from the electric trigger (if the tank version).
- Air-cooled barrel, quick-change, created by ZID technology, which provides uniform heating during firing, respectively - uniform thermal expansion of the barrel. As a result, the accuracy of shooting is increased by 1.5-2 times compared with NSV, and the circular probable deviation at a distance of 100 m leaves only 0.22 m.
In modern realities, the Kord heavy machine gun, used together with the AGS-30 30 mm grenade launcher, including the 12.7 mm sniper rifle, Igla-S MANPADS and Kornet-E "ATCM" ideally fit into the concept mobile units of special forces.
Sniper complex 6S8 "Kord"
In 2013, the Ministry of Defense after the State tests adopted the 12.7-mm sniper complex 6S8 "Kord". Sniper complex is designed for:
- damage to unarmored and light armored vehicles at distances up to 1000 m;
- damage to manpower in the means of body armor at distances up to 1500 m;
- combat snipers, which are armed with rifles of 9 or 7.62 mm caliber;
- to combat single and group goals.
The complex includes a sniper cartridge 7N34, 12.7-mm sniper rifle ASVK (6V7P), night or optical sight.
The sniper complex was created on the basis of the results of the creation of the Kord machine gun, as well as the study of combat experience gained during anti-terrorist and combat operations.
