"It is forbidden to turn on during the day without a diaphragm and direct at a bright light": about the features of the NSP-2 night sight of the 1950s

39

"It is forbidden to turn on during the day without a diaphragm and direct into a bright light." This inscription is made on the device, which was one of the first devices, as they would say now, night vision - for a combat rifle weapons... We are talking about a device designated as NSP (NSP-2) - a night rifle scope.


For the first time, the NSP device was used on an automatic weapon, namely, on a Kalashnikov assault rifle in the 1950s. Speaking specifically about the NSP-2, it began to be installed in 1956 on a 7,62 mm Kalashnikov assault rifle of the AKMSN modification.

The night rifle scope made it possible to conduct aimed shooting at targets in the dark, which, for obvious reasons, increased the effectiveness of the use of firearms. However, this complex cannot be called easy to use. There are reasons for this.

For a start, it should be noted that the NSP (NSP-2) was used not only on Kalashnikov assault rifles. They were also equipped with RPDs (Degtyarev light machine guns), as well as anti-tank hand grenade launchers (RPG-2).

The principle of operation of the night rifle scope belongs to the principles typical of illuminated scopes. The target was illuminated by a powerful headlamp. For obvious reasons, the principle is not at all the same as is characteristic of night vision devices today.

The photographs show that the NSP (NSP-2) is a device of impressive dimensions. It was connected to an assault rifle, machine gun or grenade launcher using a special dovetail mount. At the same time, the night rifle scope itself weighed almost 5 kg (4,9 kg in firing position). For its operation, a rechargeable battery was required, the mass of which was about 2 kg. The total mass of the complex based on the AKMSN with all the aiming devices was 16 kg, unthinkable today. At the same time, firing using such an aiming system was limited to about 3,5 hours - after that it was necessary to change the battery.

Indicators of the field of view for NSP-2 - 8 degrees. In this case, the scattering angle of the searchlight, which was part of the complex, is up to 6 degrees.

The complete list of items included in the NSP-2 of the 1950 model is impressive in its vastness: in addition to the sight with the diaphragm itself, it is a power supply with a low-voltage converter and a 3SC-25 battery, a bag, a case, numerous spare parts and accessories, including a light filter, a frame , drying cartridge, RB-3 spark gap, spare battery, protector, two headlights, contact nuts to the battery.

There was a special regulator on the sighting system, which made it possible to adjust the modes of its operation depending on the approximate target range, where 1 - 100 m, 2 - 200 m, 3 - 300 m, 5,7,9 - 400, 500 and 600 m, respectively ... Moreover, such modes were used for the Kalashnikov assault rifle and RPD.

So that the power cord does not interfere with the shooter, if possible, it was attached to the body with a special bracket.

Such equipment for conducting aimed shooting at night was supplied, among other things, for the USSR Airborne Forces.

It is not hard to imagine how much effort it took to at least set up this entire sighting system for firing, not to mention how much effort was expended in carrying it as part of a soldier's general equipment.

    Here is archaic ... in comparison with modern night vision devices and thermal imagers heaven and earth. Carrying 16 kg of this miracle on your hump is a thankless task ... yes, with a bright flash in battle, it can get out of order. So much work and all in vain.

          Are you a US citizen while a very wealthy citizen, in order to use the Motorola DynaTAC 8000x, model of 1983 and cost at that time - 3995 $ (for the USA at that time an impressive amount, not taking into account the monthly fee for telephone calls)?

            Not ... there were Motorola of late models, probably Chinese crafts ... I was very dissatisfied with them.
            I don’t understand just where does Motorola and NVG of the first models have to do with it?

              To understand the clearly traceable connection of technical progress, in the movement from "archaic" to the latest models of technology (no matter which one), you need to compare old phonethat you were not happy with, and your current Android ...
              And the "archaic" NSP-2, a sample of the mid-50s of the twentieth century - with the current samples.

              They were firstborn, without which there would be no future generations. What phones, what night vision devices.

                Have you brought 16 kg of this load onto the battlefield, which will be out of order from the outbreak of a projectile, and what will you do with all this economy? You will no longer have time to repair and adjust in battle.

                  As far as I remember, with a strong flash, this sight was temporarily out of order. That is, there was a continuous flare, which passed for several minutes. No fix / tweak required. But for a few minutes, the sight was really useless. Shoot from the open.

                        Not everywhere. And not all. You just don't have to confuse purely military things and those that are useful not only in the army. The protection of especially important objects, for example, as the protection of closed cities, secret enterprises, etc., is in great need of such devices. These are not grandmas with revolvers from VOKHR.

                        How is your logic? Why do the guards, the protection of places of detention, have such sights? But the plant for the manufacture of nuclear warheads, storage sites for strategic reserves, including nuclear missiles, other factories and warehouses of the Strategic Missile Forces - they, as I understand your opinion, are just trifles. The main thing is to protect the convicts. Do you work for an hour outside the "memorial"? And then they also have such a stupidly perverted logic. They say that half of the country was in prison, half of the country was guarded, and only traitors, "dissidents" and other "unworthy" solos were and are the conscience of the nation. laughing

                        You are just an illiterate person. Maroon berets do not "graze" anyone at all. Their tasks are different. There are maroon berets, there are units for the protection of especially important objects / cargo, there are convoy units, there is a guard of places of deprivation of liberty, which does not apply to the explosives at all. Learn materiel. By the way, the main task of the units for the protection of especially important is to prevent outsiders from accessing objects / cargoes containing state secrets. To eliminate any spies, terrorists, saboteurs on the approaches to the guarded object.

But no one bothers me to think and remember information, somewhere it turns out very close to the truth in practice. In your opinion, the BB is guarding military facilities of special importance? You are mistaken, any military facility is listed as belonging to its own branch of the military, which has its own guard service and special forces, the explosives from objects of particular importance only have places of confinement. Other civilian objects of particular importance are supervised by the FSO. Or can you tell us about a miracle where the explosives are suddenly guarding the Institute of Nuclear Research, maybe a mobile rocket launcher, well, at least a nuclear power plant?

    The topic is interesting. The note is superficial. Was it really impossible to write that in the receiving part there was an image intensifier (image intensifier), using an external photoelectric effect, for which a high-voltage power supply was needed. Because of this, I had to carry such a lot of weight. Modern thermal imagers operate on an internal photoelectric effect and do not require backlighting.

      which needs high voltage power supply. Because of this, I had to carry so much weight.


      Well, the weight came from the power of the headlight. She ate 25 watts from a silver-zinc battery (4,5 volts) with a capacity of 25 ah. And they did not regret it, even though such batteries are only 25 cycles and are expensive, but light. Well, you need a high image intensifier. And the converter naturally weighed too. Then there was no aliexpress with DS-DS on a microcircuit laughing

        In the 80s, they were already considered obsolete. And at the rembaz they were running around. What to store in a warehouse what to junk.
        They were not massive. Mostly they were with officers and warrant officers from the divisions who used them and were engaged in repairs.

    For the first time, the NSP device was used on an automatic weapon, namely, on a Kalashnikov assault rifle in the 1950s.

    The sight was developed by V.I. Arkhangelsky.

    The PPN-1 sight (night machine gun sight, the first sample) is installed on the company machine gun mod. 1946 This is 1948.
