Silent mortar shot: what are the features of the new project for the APU

32

In recent years, Ukraine has repeatedly announced the success of its military industry. So, Design Bureau "Yuzhnoye" has patented a silent mortar fire system.


Recall that the Design Bureau "Southern" named after M.K. Yangel, like almost all the existing Ukrainian defense enterprises, was created in Soviet times and initially worked in the field of ballistic missile production. After the collapse of the USSR, Yuzhnoye Design Bureau was one of the few enterprises that did not stop their work. Moreover, in recent years it has been repeatedly marked by ambitious statements, for example - it announced the creation of a lunar base and a jumping lunar module.

But in addition to rocket and space technology KB them. Yangelya is also engaged in more “mundane” developments in the field of conventional weapons. One of these developments is the presented concept of silent mortar shooting. Recall that in 2018 at the Ukrainian exhibition “Weapon and safety ”Rubin company has already introduced the silent whisper mortar. Now, the Yuzhnoye Design Bureau has come up with a project for a silent shot for a mortar.

The effect of the absence of noise when firing a mortar gives the locking of the combustion products of the propellant charge inside the shell. As a result, the noise of a mortar shot will be about the same as the noise of firing small arms with a silencer. The Yuzhnoye design bureau concept provides for the possibility of changing the amount of charge and adjusting the mortar firing range.

Silent mortar shot: what are the features of the new project for the APU

Silent Whisper mortar at the 2018 exhibition

What is a silent mortar shot? This is a detachable shell consisting of a warhead, a discrete propellant charge, a shank with a stabilizer and a piston with an initiating device located inside the shank. The warhead consists of a thin-walled tube, on which a set of fragmentation rings with fragmentation concentrators is fixed. At the ends, threaded shoulders are made for connecting the pipe to the contact landing pad and the connecting housing in which the propellant charge is located. The amount of propellant charge can be adjusted.


The shank body has an external thread at the edges and an internal thread from the side of the stabilizer, connected to the deforming damper and stop. The central conical and end grooves are made in the piston. Also, an alignment ring is placed in the end of the shank body from the side of the stabilizer installation.

The possibility of a silent shot significantly increases the efficiency of using a mortar in combat conditions. In the patent, among such silent mortar firing systems is called the shot NR 208A3, which equips the silent portable mortar NR 8111A5 FLY-K.

But Ukrainian experts emphasize, among the shortcomings of this system, the impossibility of changing the amount of explosive in a propellant charge, and this feature, as we know, significantly reduces the possibility of changing the firing range. In the design of Yuzhnoye Design Bureau, this deficiency was eliminated: the amount of explosive in the charge can be adjusted.

But to talk about the receipt of a new system of silent shots in mass production is still premature. After all, the first tests of the prototype did not even pass. However, it should be noted that if the production process is established, the Armed Forces of Ukraine will be able to equip silent shells for mortars and grenade launchers.

      What's the point in noiselessness? Now there are a bunch of radar stations "artillery fire notches", some in dimensions of 25-40 kg, which are just designed for instant detection of the departure of a mine - they don't give a damn, whether there was a noise of a shot or not. For sabotage? To drag a heavy shnyaga (which later will have to be thrown, and it costs money) to release from two dozen mines brought in (it will be difficult for a small group to drag more) - is the game worth the candle? It is much easier to bring with you an RPG-7 type grenade launcher with the same number of shots or disposable ones. Or even better, if you need to quickly hit a point, protected ATGM target. The point in this "silent" shnyaga? Fired several pieces of "silent mines", received a notch from a counter-battery station and then a response from "loud" mortars, missile defense systems or enemy artillery?

      The range of the mines depends on the mounted powder charges, which are installed in front of the stabilizer mines.

      From the description of 82-mm mortars of the BM family on Wikipedia:
      For firing from an 82-mm mortar, high-explosive fragmentation shells, six-feather and ten-feather mines and six-feather smoke mines, as well as an agitation mine, were used.
      The 82-mm six-armed fragmentation mine O-832 weighed 3,31 kg (equipped with additional charges - 3,4 kg) and carried 400 grams of explosives. A mine explosion gave 400-600 fragments, which ensured the defeat of manpower within a radius of sixty meters from the gap.
      The 82-mm fragmentation ten-armed mine O-832D also weighed 3,31 kg (equipped with additional charges - 3,4 kg) and carried 400 grams of explosives.
      82-mm smoke six-armed mine D-832 weighed 3,67 kg.
      A 82-mm A-832 ​​propaganda mine weighed 4,6 kg.

      As you can see, for some reason they were busy.

      Russian silent mortar "Gall" copied in Ukraine
      Ukrainian "designers" continue to engage in shameless theft of Russian developments. So, at the exhibition "Arms and Security 2018" in Kiev, the 82-mm silent mortar "Whisper" was demonstrated.
      This development by one of the Ukrainian companies is very similar to the Russian 2B25 "Gall". Differences are only in small details.
      If we talk about the technical characteristics of the "novelty", it turns out that it is inferior to our sample. While the 2B25 has a maximum firing range of 1200 meters, the Whisper has 400 meters less.
      The rate of fire is indicated at the same -15 rounds per minute. The same vertical guidance angle - 45..85 degrees. If "Gall" weighs 13 kg, then its clone is 16,9 kg.
      Special mines are also very similar.
      a photo2B25 "Gall"

      The 82B Gall portable infantry 2 mm mortar is primarily intended for the destruction of enemy manpower in the open and in field-type fortifications (trenches and trenches). The main feature of the gall is its noiselessness, which allows a mortar crew of two people to secretly fire at enemy positions and quickly change their position.
      Silent and invisible 2B25 "Gall" is achieved by the absence of standard effects when fired (smoke, sound. Shock wave). Such characteristics were achieved thanks to the special 3VO35E fragmentation munition, which is used in the gall. The scheme of such firing was already applied earlier, but in a special self-loading pistol PSS. When a mortar is fired from a mortar with 3VO35E ammunition, the powder gases are locked in the tail of the mine and remain there, while there is no shot flame, smoke, sound and shock wave. Some experts note that the sound of volley from the 2B25 Gall mortar is comparable to a shot of a Kalashnikov assault rifle that is equipped with a silencer or a Makrov pistol shot. That is, you probably imagine that this is a fairly quiet and dull clap, which is almost indistinguishable at a distance of more than 100 m .. The mortar calculation of the gall allows you to hit the enemy at a distance of 100 to 1200 meters, at fairly good angles of +45 - + 85 degrees, horizontal angles of rotation of the installation vary from −4 to +4 degrees. As mentioned earlier, the 2B25 Gall combat crew is 2 people, and the ammunition caliber is 82 mm. The weight of the mortar is 13 kg, and the rate of fire varies around 15 rounds per minute.

      Caliber: 82 mm;
      Calculation: 2 people;
      Firing range: from 100 to 1200 m;

      There are measuring bags with gunpowder in the form of sausages, they are tied around the shank. Reinforced propellant like seems to be used since the Second World War at least.
      You can throw a mine further than the passport range, if the design of the mortar allows.

        In any case, this topic is not for mass use. As well as small arms silent weapons (by the way and according to the same principle of locking the powder gases in the case), did not become widespread. In single copies, for special forces. Apparently, "the game is not worth the candle" and the topic is good only from the point of view of "academic interest".

    The technical solution is, of course, interesting ... but what's the novelty? There is no particular novelty ... except perhaps a variable propellant charge! But even here everything was predictable! That is, the "design" of a variable propellant charge in a "silent" rod mortar, for example, was known to me from the moment the first reports about the "Gall" mortar appeared ... By the way, the idea of ​​"silent" (and not only "silent" ... ) rod mortars (and not only rod mortars ...) appeared much earlier than the appearance of the "Gall" mortars! "Similar" mortars were used back in WW1 ... they were also in WW2 (there was a similar mortar in the Red Army in WWII ...) From the post-war devices I remember the Georgian 60-mm mortar ... we are not talking about the "NATO" mortars yet, but and they are ...! In general, you can count 3 (!) fundamental technical solutions for creating "silent" mortars: 1. core; 2. With telescopic shank; 3. with a "choke" ...! As you know, "silent" mortars (especially the first two types ...) have a short firing range and "light" ammunition ... To "underestimate" these shortcomings, you can use active-jet mines, mines with longer shanks and mortars with longer barrels ... Among the advantages, one can even attribute not so much "noiselessness" as the low weight of the weapon, moreover, with the expected cheapness ...! In rod mortars, for example, you can use thin-walled aluminum barrels!
