Heavy machine gun NSVT: overview, features and description

The Guns while their appearance is not accidentally related to the category of artillery: the power of such weapons is striking to this day. Moreover, the heavy “stancati” allow even curtain fire, so artillery systems they can, albeit with a stretch, be attributed even today. Could not be better, this thesis confirms the legendary machine gun NSVT, aka “Rock”.

Basic information and purpose

Refers to large-caliber guns (12.7 mm). Created for the following purposes:

• The Suppression and destruction of emplacements and light armored vehicles.
• Work on clusters of light machinery and manpower of the enemy at distances up to one and a half-two kilometers.
• Possibility to use as air defenses to destroy targets flying at altitudes up to six kilometers.

Powerful Soviet cartridge 12,7h108 allows you to perform a whole range of different tasks, as produced in different variations (including standard and armor-piercing bullets):

• Bromelaine-zazhigatelnye.
• Traceroute-Bronevaya-zazhigatelnye.
• Special incendiary, instant action.

How to create this machine gun?

On a new machine gun was initiated in the early 60-ies of the last century, since by that time, finally there is a need to fully replace the outdated DShK (DSHKM). By the way, later authors took part in the competition for the creation of a single machine gun caliber 7,62x54r, but then won the Kalashnikov.

By the Way, where is the name of: "NSVT machine gun"? Decoding is simple because it's an acronym composed of the first letters of the names of the creators of this weapon: Nikitin, Sokolov, Volkov. The index of the “T” means “tank”, but often so called and the infantry option.

Especially for the production of new weapons from scratch the factory was built in the city of Uralsk. Moved a lot of workers, and “gun” of the towns: Tula, Izhevsk and Kovrov. Together they managed to create a totally unique technology for the creation of weapons, which until that day was not used anywhere:

• Rifling was prepared by electrochemical and mechanical processing. This enabled to minimize the likelihood of microscopic damage to the trunk, extend the duration of its use several times.
• Heat the vacation was carried out in a vacuum chamber, thereby to achieve uniform hardening without defects.
• Jet chrome plating the entire barrel channel is also repeatedly increased its combat survivability.

The design and first field tests in the design of “Rock” there have been many changes, most of them aimed at enhancing the combat survivability of the weapon and its maximum simplification.

Production site

Except the Soviet Union, produced a machine gun NSVT in India, Bulgaria and Poland. Incidentally, the license for the “Cliff” has handed over to them together with the right to manufacture T-72 tanks. It is known that a similar resolution has also received Iran but, apparently, difficult to establish the production of machine guns in its territory and did not work.

Military use

For the First time a machine gun NSVT was successfully tested in Afghanistan. In the first months of the war both sides used exclusively by the ANC (the spooks it was a Chinese copy). But soon our troops began to move EN masse on “Rocks”. Its huge advantage was a simple fire control system, precision and accuracy.

If our soldiers were spotted approaching the Outpost of the Afghans, those plans changed dramatically as to approach at a distance of aimed fire from the machine gun to the checkpoint, where there was a machine gun NSVT, was unreal. Originally used for these purposes tank option on the machine, but later the troops went purely infantry modification.

Soon the gun firmly “rooted” on all types of Soviet tanks, self-propelled guns and other armored vehicles. Fell in love with NSVT (machine gun) and in the Navy, where he massively installed on patrol boats as a simple and effective means of self-defense, including from low-flying enemy aircraft.

Key benefits

In both Chechen campaigns, and the gun also showed his best side. Moreover, there is “Cliff” has acquired the nickname “anti-sniper”. As this gun allows to fire at a distance of flesh to two kilometers of militant snipers just milled together with shelters. But even more appreciated by our soldiers of this technique, when the troops finally began to put and the normal sights:

• Standard stamps SPP.
• Night NSPU-3.
• Unique radar sight, which allows with exceptional accuracy to fire even in the dark, when the usual “lamp” have become almost useless due to blowing out.

Of Course, in the late 80-ies already acutely the need to replace the “Rock” for something more modern, but it still stands on the armament of our army. But the change of the machine gun is really decent – “Cord” production of the legendary Kovrov arms factory. What was so good from the structural point of view NSVT? This machine gun – whole “meeting” unique technical developments, in many ways ahead of his time.

Design Features

First, the weight. Only 25 pounds! For guns of this caliber it is today the minimum achievable weight, despite all the achievements of material science. Automation “Rock” is a classic, based on removal of powder gases. The locking shaft is carried by breech, with his earring, at this time hits the firing pin. So elegant and simple solution has greatly simplified the design of the weapon.

The Trigger mechanism is also very simple and allows only automatic fire. The arms can be connected by “block” or with a trigger or with electric drive (on the tanks). Arm to reload.

Almost all the internal moving parts fitted with rollers designed to minimize friction. To increase survivability mechanics, it is “fat” cadmium plated. Thanks to the elaborate scheme of Assembly and disassembly, the replacement of the barrel could easily carry out directly in the field, in the shortest possible time. For ease of replacement provided by the trunk handle. The muzzle-flash suppressor characteristic conical shape, which have been derived from the ANC.

Are There any differences in “armored” NSVT? Gun tank in its design is no different from a simple infantry varieties, with the exception of the trigger device. His role is a simple coil winding and a pull rod. When the device is supplied current, the latter starts to move, pressing on the “trigger”. Since the construction is simple to primitivism, it is extremely reliable, because there is nothing to break.

Bolt carrier with gas piston and the gate are connected pivotally. The ammunition supply – by means of the metal strips, it is possible to right and left options. The exclusive feature of “Rock” is a front ejection of spent cartridges, allowing you to use this weapon to create a paired gun emplacements. In particular, at the time, were produced in Tula. Efficiency paired “Rocks” little inferior to itself even at the Shilka, while the rate of the latter, of course, above.

Sighting mechanisms, and ammunition supply of the gun

As sighting devices include front sight and a folding strap, marked up to a distance of two kilometers. Originally folding was and fly, but experience has shown that this design is no good.

The ammunition supply of ribbon type coupling “crab”. Each piece consists of ten units. The design is such that it is possible to collect the tape of any arbitrary length (but not less than ten cartridges respectively). It is collapsible, in case you need the pieces quickly reteplase. Along the longitudinal edge of the interlocks applied white stripe, so in combat is not necessary to think long where to attach the additional pieces.

Press

Option for the infantry machine gun NSVT “Rock” is used with the machine brand 6T7. The machine is designed, provides excellent positional adaptability, allowing to conduct aimed fire from various positions. For convenience, the arrow is designed spring-loaded shoulder, which greatly softens the impact.

For anti-aircraft firing of infantry machine not intended. Thanks to its design as simple as possible, and weighs 18 pounds. In the transport position 12.7 mm machine gun NSVT it is removed, and the machine folds up and can be transferred to the hands.

Modifications

The Main modification – it is just the same NSVT, which was put on all the Soviet tanks, since the late variants of the T-64 and other booking...
