Self-propelled guns 2S34 "Khosta" participate in the Special Operation

Self-propelled artillery of all main types plays an important role in the current Special Operation. The Ministry of Defense regularly demonstrates the combat use of various domestic self-propelled guns. A few days ago, for the first time during the operation, the combat work of 2S34 Khosta self-propelled guns and their crews was shown. Such SAOs, using a wide range of ammunition, support infantry and destroy enemy fortifications.

Unofficial data

As is now known, Khost self-propelled guns have been present in the zone of the Special Operation for a long time. However, for unknown reasons, until recently, their participation in battles was known only at the level of rumors and fragmentary data. Evidence of the use of such a technique appeared not so long ago.

In mid-January, a curious video, filmed at an unknown time and in an unknown place, was distributed on specialized resources - its authors took measures to protect sensitive information. A military echelon with a large number of armored vehicles, domestic and captured, got into the frame. Cars were taken inland for repairs and restoration.

Along with other objects, two 2C34 type SAOs were present on the echelon platforms. The letters "Z" and the call sign "Sword" were present on the sides of both cars. Self-propelled guns had obvious traces of long-term operation at the front, and damage to the undercarriage was also present.

Judging by the date of publication of the video, two Hosts arrived at the repair plant a long time ago. It is likely that they have already been restored and are ready to return to service, or even managed to get into the combat unit.

Two "Hosts" got into the frame for just a couple of seconds, but this is enough for conclusions. For the first time it became known that such equipment is also involved in measures to demilitarize the enemy. At the same time, her condition indicated that such participation had been going on for several weeks or even months.

Ministry of Defense informs

The first official announcement about the participation of the SAO "Khosta" in the Special Operation appeared only on February 16th. The Ministry of Defense said that self-propelled guns from one of the formations of the Central Military District are operating in the combat zone. Singly and in pairs, around the clock, they fire at enemy positions. Accurate fire is provided by reconnaissance and unmanned aviation.

Also posted a video with the work of gunners. The hero of the video was a combat vehicle with the call sign "New". Demonstrates how to get into position and prepare for firing, and then the CAO opens fire. All processes are shown outside and inside the fighting compartment. Also in the video you can see the explosions of shells on enemy positions. After firing, the self-propelled gun leaves the position.

The command platoon commander said that Khosta provides infantry support and fires at various targets, from fortifications to manpower. Ammunition is selected according to the type of target. Mines and shells in caliber 120 mm are used. In some situations, the crews have to conduct intense fire - up to 58-60 shots from one position.

For ground forces

The promising self-propelled artillery gun 2S34 "Khosta" was created in the nineties by the Motovilikhinskiye Zavody (Perm) by order of the Ministry of Defense. The aim of the project was to carry out a deep modernization of the serial self-propelled guns 2S1 "Gvozdika" with the replacement of the main armament. It was proposed to use the developments under the projects "Nona-S" and "Vienna" and equip the existing fighting compartment with a "universal" 120-mm system based on the so-called. ballistic scheme "gun-shot".

In the XNUMXs, the experienced Hosts passed the entire test cycle. The self-propelled gun confirmed the design characteristics and received a recommendation for mass production and adoption. By the beginning of the XNUMXs, Motovilikha Plants mastered the production of a new model of equipment and shipped the first self-propelled guns to the customer.

Product 2S34 is intended for artillery units of the ground forces. With its help, a gradual replacement of the old 122-mm Gvozdika systems is carried out. To date, according to various sources, at least several dozen Khosta self-propelled guns have been built, which made it possible to completely re-equip a number of units.

The gradual transition of artillery units from the 2S1 self-propelled guns to the 2S34 self-propelled guns has several positive consequences. First of all, this is a reduction in the age of equipment in service. The newest "Carnations" were built in the early nineties and, despite repairs and upgrades, are approaching the development of a resource. In addition, the 2S34 self-propelled gun has special weapons with advanced capabilities. In this respect, it is superior to the older 2C1.

Universal system

2S34 "Khosta" is an armored combat vehicle on a tracked chassis with a fully revolving turret equipped with weapons. Like other self-propelled guns, the Khosta is intended to destroy manpower, artillery batteries, command posts, etc. targets at the forefront and in the near rear of the enemy. At the same time, its complex of weapons makes it possible to more effectively solve such problems.

SAO 2S34 is built on the modernized Gvozdika chassis. It has a welded armored hull made of rolled steel sheets. Bulletproof / anti-fragmentation armor protection has been retained. The bottom of the hull has been reinforced to improve resistance to blasting. In the bow there is a YaMZ-238N engine with a power of 300 hp. and transmission. The undercarriage has seven road wheels with torsion bar suspension on board. On the highway, a speed of 60 km / h is reached. Like its predecessor, "Khosta" can swim.

A 2A80-1 universal gun with the functions of a cannon, howitzer and mortar is placed in the turret on a rocking mount. The gun has a rifled barrel of increased length with a developed muzzle brake, and is also equipped with a semi-automatic shutter. The rotation of the tower provides a circular aiming horizontally; vertical angles up to 80°.

40 shots of any type are transported on board the Hosta. The gun is capable of using a wide range of 120-mm ammunition of various types and purposes. High-explosive fragmentation, incendiary, etc. have been developed and introduced. shells. Massive 120 mm mines are also used. It is possible to use guided projectiles. Depending on the ammunition used, the firing range reaches 9-12 km.

The SAO is equipped with a modern fire control system capable of calculating data for firing all compatible ammunition within the entire range of ranges. The FMS includes an optical sight for direct fire and a panorama for working in closed positions.

In terms of dimensions, the Host is practically no different from the Carnation. The combat weight has increased to 16 tons. The crew, as before, includes four people. A driver works in the body of the vehicle, and in the fighting compartment there are places for the commander, gunner and loader.

Moment of glory

From the point of view of performance characteristics, operation features and combat capabilities, the 2S34 Khosta self-propelled gun is a modern and successful replacement for the well-deserved, but aging 2S1 Gvozdika installation. Obtaining such products has a positive effect on the fire capabilities and the overall potential of artillery subunits and units.

Together with other artillery systems, the Khosta SAO is used in the demilitarization of Ukraine. Such equipment has been present in the war zone for a long time, but it was officially shown only now. Calculations of self-propelled guns do their job and help achieve common goals. And it's good if they continue to receive their share of attention.

How, all the same, Russia is slowly re-equipping with modern models of military equipment (Su-57, Armata ...)!

[Amateur]

All these "Khosts", "Kudepstas" and other "Armata" are worthless in modern warfare if they aim with the help of an artillery compass, which was used by the grandfather of the current artilleryman.
TV "Zvezda" regularly shows in the news about the SVO how these compass are used to aim artillery. At least they didn’t show them, they didn’t disgrace themselves.

May I ask how far from the front line is the person who uses the compass?
Or ... How does he transmit the corrections to the commander at the firing positions?
Or ... How long will this group last in the shelter, shining with the lenses of the compass and heads?
Back in the 80s, there were topographic surveyors on command vehicles. We tried to move with their help ... It did not work out. According to the map it was one thing, but in kind it was another ...

[Vladimir 290]

the man with the compass is not "How does he transmit the corrections to the commander at the firing positions?" - he is located directly on the firing line, and the commander (batteries, divisions ...) controls the fire, who is located at his observation post at the forefront.

[insafufa]

Quote: Ivan 1980

Well, there is a solution already when instead of a compass they put a computer station and a Glonas receiver, and each gun counts and fires at the coordinates by itself. And there are fire control vehicles with the same stations for controlling the fire of 2C3 howitzers in 2001. They were and were used there; the compass is built in the form of a prism and allows you to aim even more accurately.

[Alexey Lantukh]

Well, there is a solution already when instead of a compass they put a computer station and Glonas

As a former topographer RV and A (service in the 70s), I understand in linking artillery positions and guidance. It is clear that the position coordinates are now easy to obtain via GLONASS, not that it used to be sometimes a problem. But, getting a direction (direction angle) using glonass is not so easy without dancing with a tambourine. You need either a gyrocompass (built into a self-propelled gun or separately) or the same universal non-electronic compass, which is not afraid of any interference. By the way, the compass, together with the rangefinder rail, can be used to determine the coordinates of the position, which was a rather gimmicky task.

[_RUSSIAN_BEAR_]

You shouldn't think so. In the conditions of modern man-made combat, all options for countering this technique will be used. One of them is computer jamming on the equipment itself.
And how will the gunners work?
In the old fashioned way, they will.

Do you know why the Americans defeated the Iraqi army, armed with Soviet-made weapons?
And for that too, BUT...
Iraqi soldiers and officers were lost in space, and could not determine which side the enemy was (without seeing him) and what to do (without receiving orders from the command) ...
The loss of command and control of the troops is the main reason for the defeat ...

[svoroponov]

The main reason is that they are not fighters, but historically traders and a donkey with gold for their command from the opposite side, won.
In order to judge that war, it is far from enough to read only the Americans, who write only in a light favorable to them. The Iraqis knew full well where the coalition was. The main defeat of their tanks was carried out by helicopters and aircraft. Tanks were just finishing off Iraqi equipment. You need to know that Iraqi aviation practically, except for individual cases, did not resist the Americans, but they simply took and flew to Iran, where they were interned by the Iranians.
I will give an example of a single resistance of the Iraqis. An Iraqi MiG-25, an interceptor carrying missiles, was sent to reconnoiter the enemy. To intercept it, the Americans sent two pairs of F-15s. The first pair fired missiles and missed, as the MiG noticed them in time and began to maneuver. An air battle ensued. One F-15 was shot down and another one was damaged and left the battle. The remaining two Americans, having used up all the possibilities of combat, requested help and, since the ammunition and fuel were running out, left the battle. MiG - similarly left the battle and began to leave in the direction of his own, also on the remnants of fuel. This is where the help of the Americans caught him and they got him.
It's true that's what they write. According to the Iraqis, their plane crashed after using up all the fuel and the pilot ejected and they were able to pick him up. Here is an example when the Iraqis provided worthy opposition to coalition aircraft.

[Proctologist]

the main reason is that they are not fighters but traders historically

- this is not a reason, this is an excuse, deliberately misleading. [Soviet] weapons are good, but Arabs don't know how to fight, cowards. Well, who was misled by this? Themselves?..

The Iraqi army fought with Iran for many years, had not just trained, but with current combat experience, acting officers and fighters, who used modern Soviet technology not in exercises, but in real battles.

[Aviator_]

The Iraqi army fought with Iran for many years, had not just trained, but with current combat experience, acting officers and fighters, who used modern Soviet technology not in exercises, but in real battles.

It, of course, seems to be so, but the Persians simply did not offer them money, since the Sunni Iranians could not take money from the Shiites of the Persians. And from the Americans - always and in large quantities.

[Aviator_]

I call, Sunnis are still Iraqis. and I blurted out "Iranians"

[Sergej1972]

In fact, more than half of Iraqi Arabs are Shiites. But under Saddam, the Sunnis dominated the power structures.

[Guran33 Sergey]

What are you arguing about here? In Iraq, everything was decided by "a donkey loaded with gold at the gates of the city." Most of the higher ranks simply merged the army .. For this they were not touched, and even for the first time, while the partisans were crushed from their posts, they did not remove

[Muromczev-2015]

After the suppression of Iraqi air defenses, the US had complete air supremacy, and missile support from the sea. Your example with Soviet weapons is completely incorrect: the US army was an order of magnitude more powerful than the Iraqi one, and no tanks would have helped here.

[UAZ 452]

And how will the gunners work?
In the old fashioned way, they will.

And then the infantry must be immediately armed with a club - no electronic warfare is terrible for such a weapon, and even if the enemy destroys the ammunition factories, it's okay.

[Guran33 Sergey]

As a result of this operation, where the electronic warfare installations did not really work, real products that are convenient and effective in combat conditions will appear .. And most likely the first samples of the new generation are already being made in hardware

[AlexVas44]

There are eternal values ​​..... I can assume that in 100 years the compass will remain.

[Georgy Sviridov_2]

Of course it will. This is universal crap, because GLONASS data can distort, or even destroy satellites ...
In the end, electronics can simply fail and the crew must be able to work without it ...
It is clear that it is more convenient and faster with him, here they are already returning to paper maps in NATO ...

[Andrey Georgich]

Well, fortunately, where the enemy is now, according to GLONASS, the artillerymen know. Commands for adjusting hits are received by radio. The ballistic computer allows you to make corrections with minimal errors. It seems like no one canceled gravity. If a person understands how the compass works and how to use it, he will a priori get both with and without a computer.

[Georgy Sviridov_2]

In Khost, unlike Gvozdika, you can aim without a compass. There, the machine is immediately tied to the coordinates, and the suo itself calculates both the azimuth and the elevation of the trunk. This is just their difference, unlike carnations.

[Bogalex]

Yeah. And how does the FCS calculate the azimuth of the car during the initial orientation? Also on GLONASS? Or do you think that the "Host" has a gyroscope?

[Alexey RA]

The self-propelled guns "Khosta" enters the troops under the index 2S34. As part of a deep modernization of the prototype, the 2S1 Gvozdika self-propelled guns, the Khost carried out work not only to replace the 2A31 howitzer with a semi-automatic gun that combines the capabilities of a mortar, howitzer and cannon, but also many other innovations. The most important of them are automatic recovery after a gun aiming shot (due to the installation of servo drives), the appearance of a gyroscope on the cradle of the artillery unit of the self-propelled guns, coupled with the CVC.

So they also show the wheels, which they invented a thousand years ago, maybe they don’t show it either? Well, are you a disgrace to your own heart with such posts?

I agree, but the compass should not be forgotten! Electronics is a good thing, but it is vulnerable and in the event of its failure - old-fashioned methods are just right.

Yeah ... July 12, 2022, the capital of the Czech Republic - Prague, an exhibition of captured Russian equipment captured by the Armed Forces of Ukraine and there was such an exhibit

does it remind anyone of anything?

The bottom of the hull has been reinforced to improve resistance to blasting.

How interesting! The Gvozdika bulletproof armor was taken and deeply modernized into the Hosta armor, which has a reliable and durable body with increased resistance to anti-tank mines ... And who checked this?
Maybe "Lepestkov" and other PPM?
All deep modernization of Soviet developments consists in replacing tube electronic devices with semiconductor ones with microcircuits from Taiwan ...
Deep modernization allows to reduce the number of crew members, increases operational characteristics, increases the firing range by at least 40% using a computer that provides instant topographic location and coordination of firing with various reconnaissance systems.
I am simply silent about various precision-guided munitions.

Excuse me, but how does "the firing range using computers increase by at least 40%" due to "instant topographic location and coordination of firing with various reconnaissance systems"? Can you explain?

"The aim of the project was to carry out a deep modernization of the serial self-propelled guns 2S1" Gvozdika "with the replacement of the main armament" ... They took and replaced a 122 mm cannon firing at 15 km, with a 120 mm mortar firing at 8 km. with the same ammunition .. And this is definitely a replacement for "Carnation" ?????

[Georgy Sviridov_2]

Not by 8, but by 13. Because 120 mines are much more powerful, plus 120mm guided projectiles are much more.

[Bogalex]

When they hit you from 15 km away, and you have nothing to answer with, will the higher power of your 120-mm shells calm you down and allow you to think that it's okay?

[Bogalex]

Relying on the stupidity of the enemy is not the best course of action. Talk to SVO members. They will tell you which of the scenarios happens more often. And even more precisely - which one happens with enviable regularity, and which one - almost never.

[nehist25]

Why do you think so? Mina 120mm with a maximum of 5 kg of explosives against 7 for a 122mm projectile. The range of 122mm is greater and who prevented guided projectiles for this caliber from being made? The benefit of systems 122mm caliber over dofiga was

[Georgy Sviridov_2]

It’s bad that the Host made a trial batch of 50 pieces and that’s all, then they were abandoned. And on the host is a modern suo, making them many times more effective than old carnations. Yes, and 120 mines are more powerful than 122 mm shells. And most importantly, there are many more high-precision kitolov-2 shells than high-precision kitolov - 1 (122mm), I haven’t even seen such ones at exhibitions ...
It is clear that during the NWO, carnations and d-30 will serve, but then the d-30 must be taken to the reserve, leaving a reasonable amount for the airborne forces.
But carnations cannot be written off, they must all be upgraded to Host.

[Bogalex]

And on the host is a modern suo, making them many times more effective than old carnations.

And if we ignore the seemingly axiom that the presence of an SLA is better than its absence, and go to the point, how exactly does the presence of an SLA make "Hosts" "many times more effective" than "Carnations"?

Yes, and 120 mines are more powerful than 122 mm shells.

Pretty controversial statement. Depends on the type of target and the task of shooting.

[Georgy Sviridov_2]

The presence of a self-propelled gun increases the speed of deployment and guidance, significantly increases the accuracy of firing, plus it allows you to fire at the enemy’s position in the art raid mode, when the self-propelled gun fires several volleys at the target (naturally not at maximum distance), with different elevation of the gun and charge, with such a calculation that they fall on enemy positions almost simultaneously, and at this time the complex itself turns off and changes its position. Plus, the suo allows you to work effectively on direct fire positions.
A mine, unlike a projectile, has a much larger canopy of explosives and creates more fragments.
The only thing, I don’t know why, but everywhere there is an emphasis that the host, unlike the vein (and lotus), cannot use cumulative shells ... This is really a minus ... But since veins / lotuses can, I think hosts can be finalized, so that they can.

[Bogalex]

Well, in order.
The FCS (in relation to the "Khosta" it would be more correct to call it ASUNO) improves the accuracy of firing only in the case of interaction with a vehicle from the fire control automation complex (KSAUO). Otherwise, she simply has nowhere to automatically receive installations for firing. Do you know at least one KSAUO battalion level? The tablets available in the troops mainly implement the tasks of calculating installations for firing and help gunners a lot, but are they able to interact with ASUNO "Khost"? As far as I know, no. Although maybe I'm behind the times.
Further. The accuracy of fire when using ASUNO increases, yes, but does it level the accuracy of firing of the Khosta gun itself in comparison with 2S1? The fact is that due to the design features of the projectile-barrel system, combined guns have obviously worse accuracy compared to classic rifled guns. Such was the price for "omnivorousness".
The Khosta's rate of fire is lower than that of the 2S1. This is due to the use of a very specific design of the propellant charge, which, moreover, is not protected by a sleeve and has much lower safety characteristics than the "classic" on 2C1.
To the implementation of the so-called. the "art raid" mode of the SLA has practically nothing to do with it. In manual mode, it is just as easy to implement and just as useless in practice as it is when using the SLA.
To be honest, I didn’t understand about the efficiency of direct fire with the FCS. There is nothing more effective for direct fire than an optical sight, and cannot be. SLA has nothing to do with it at all.

A mine, unlike a projectile, has a much larger canopy of explosives and creates more fragments.

I love false statements
In fact, the 122-mm projectile OF-462Zh carries 3,97 kg of explosives, OF56 projectile - 4 kg with kopecks. For comparison, the most widespread 120-mm mine OF-432 has in its composition 1,4 kg of TNT, more advanced OF34 - about 3,5. Do you feel the unconditional superiority of mines?
Fragments of a 120-mm mine weighing 16 kg also cannot create more than a projectile weighing more than 21,5 kg - the volume of the source material for the formation of a fragmentation field is obviously and noticeably smaller.
Another thing is that the conditions for the approach of a mine to a target are usually much better - fewer fragments go into the ground and their distribution over the affected area is much more effective. But for this, non-contact detonation can be used in artillery. With it, the described advantages of the mine are leveled.
"Khosta" cannot use cumulative projectiles due to the presence of a highly developed muzzle brake. Although I personally do not see any minus in this. "Lotus", by the way, can't either.

[Bad_gr]

The self-propelled guns "Khosta" enters the troops under the index 2S34. As part of the deep modernization of the prototype, the 2S1 Gvozdika self-propelled guns, Khost carried out work not only to replace the 2A31 howitzer with a semi-automatic gun that combines the capabilities of a mortar, howitzer and cannon, but also many other innovations. The most important of them automatic recovery after firing the aiming of the gun (due to the installation of servo drives), the appearance on the cradle of the artillery part of the self-propelled guns of a gyroscope associated with the central air control complex.

In the 2S34 self-propelled guns, other design solutions were adopted that are used in the promising sighting and navigation system 1V180-2, which is planned to be fully installed on the new 2S35 self-propelled guns (work on it is currently underway). All these improvements allow us to talk about a significant increase in the combat effectiveness of the new self-propelled guns in the 2S34 modification (almost three times).

2S34 "Khosta" can fire 120 mm ammunition, the effectiveness of which is comparable to high-explosive fragmentation shells of 155/152 mm caliber, all currently available mines of 120 mm caliber (manufactured by the USSR, Russia or NATO states), the latest guided high-precision projectiles of the type "Kitolov-2", equipped with a passive seeker. The design of the seeker allows you to receive signals from a laser designator reflected by the target.

For the first time on self-propelled guns of this class installed automated control system, which aims the gun in two planes according to the data for firing, previously calculated by the system itself. The ACS topographic and geodetic referencing system is duplicated (satellite and autonomous orientation). The accuracy and accuracy of firing has been significantly increased due to the installation of a new round-the-clock optoelectronic reconnaissance and target designation system.
The improvements carried out as part of the modernization allow us to say that the 2S34 Khosta self-propelled guns will still be among the most effective fire systems of its class in terms of their combat characteristics for a long time to come. Its aimed rate of fire has increased from 4 to 9 rds / min. The combat capabilities of the ammunition used have almost doubled. The minimum range of ricochet-free firing with high-explosive fragmentation shells was reduced from 4 to 1,5 km, mines - up to 0,4 km. At the same time, the maximum firing range remained unchanged.

Design solutions (installation of an overheating indicator on the barrel, its cooling systems, reduction of the gas contamination of the combat compartment, etc.) applied during the production of 2S34 had a positive effect on firing modes and reducing the time required for the calculation for the first shot. The calculation of "Hosts" received the possibility of two-way telecode communication with higher levels of control.
.........A full-scale modernization of the on-board equipment of the new self-propelled guns to the level of 2S34 is planned at the first stage only for command vehicles (from the battery commander and above). The rest of the self-propelled guns are equipped with an SLA in a somewhat truncated form (an analogue of the automated guidance and fire control system "Success-S").

As an option, the use of self-propelled guns 2S34 "Khosta" in conjunction with automated artillery fire control machines of the "Kapustnik-B" type and the "Zoo-1" complex, which carries out artillery reconnaissance, is being considered. The combat capabilities of installing vehicles that have undergone partial modernization are somewhat reduced without these units. However, they will still be an order of magnitude higher than 2C1.

When they talk about "Khost", they mention compatibility with 120mm caliber mines with NATO. They are also armed with the MO-120-RT-61 mortar by the French firm Thomson-Brandt.

The mortar began to enter service with the French army in 1973. Until 1982, 240 such mortars were delivered, and in subsequent years, about 300 more. The mortar is also in service with the armies of some other countries of the world, in particular, the Netherlands and Germany.
The mortar consists of a rifled barrel with a breech, a carriage with wheels and a base plate. The barrel has a length of 17,3 calibers (2080 mm). In the barrel bore, rifling is made like the barrel of a conventional artillery gun ...........
........... For firing from a mortar, special mines have been developed and are being produced in the form of an artillery shell. Compared to conventional drop-shaped mines, they are filled with more explosives and are characterized by increased accuracy of fire. The leading belts of these mines have ready ledges. When the mine moves in the bore under the influence of powder gases, the protrusions slide along the grooves of the bore, due to which the mine acquires a rotational motion that stabilizes it in flight.
_ The firing range of a high-explosive fragmentation mine weighing 15,7 kg (initial speed 365 m/s) is 8135 m. m/s. Grooves are made on the body of this mine to produce large fragments when ruptured, designed to destroy lightly armored combat vehicles. All mines of 13000-mm smoothbore mortars can also be used for firing from a mortar.
......... At Thomson-Brandt, work is also underway to create 120-mm mines with cluster warheads. In particular, one of the samples will have 20 cumulative fragmentation elements ejected from the mine body at a height of about 300 m and scattered over an area within a radius of 40 m. The company's specialists are also developing a new model of a 120-mm active-reactive mine with a firing range of up to 17 km (weight 24,5 kg, length 1,2 m). ....

According to rumors, this mortar served as a prototype for the creation of 2A80-1
Question:
is the Hosta compatible with this mortar in terms of ammunition?

[Bogalex]

"Khosta", like its predecessor, 2S9, is compatible with all foreign-made 120-mm mines. The only question is whether there are shooting tables for them.
Since foreign mines were not massively supplied to the Russian Federation (I remind you that more than half a thousand of them are required to shoot shooting tables), it is most likely that the ability to shoot foreign mines is nothing more than a PR move by Rosoboronexport. And for our guys with "crosses" on shoulder straps - another suitcase without a handle.

"Khosta", like its predecessor, 2S9, is compatible with all foreign-made 120-mm mines.

The Hosta, like the MO-120-RT-61 mortar, has a rifled barrel, part of the ammunition load, as I understand it, with pre-cut grooves for cutting the barrel - do they coincide with the Frenchman at the Hosta?

[Bogalex]

I can't say for sure about the shells. Most likely no.

[Georgy Sviridov_2]

Well, if some option is not available, then this is a minus. There is nothing wrong with cumulatives.
Mine and shells of low-ballistic guns, less thin-walled, as a result, when they break, a larger number, but smaller fragments are obtained ... If this were not the case, no one would ever use low-ballistic guns ...

[Nikolay Dyaglev]

Strange and incomprehensible praises. Why is it better than Cloves then? And there were videos from the front line a long time ago about the Host and its towed version. So-so article...

[Bogalex]

The Hosta does not have a towed variant.

Product 2S34 is intended for artillery units of the ground forces. With its help, a gradual replacement of the old 122-mm Gvozdika systems is carried out.

I wonder how in this way, given that the Gvozdika is a regimental weapon, and the Khost is a battalion weapon?

In addition, the 2S34 self-propelled gun has special weapons with advanced capabilities. In this respect, it is superior to the older 2C1.

Well, yes, well, yes ... The range of "Hosts", as the author himself writes, is up to 12 km. "Carnation" sends shells to 15 km. How "important" the difference in firing range is, the current hostilities have shown more than clearly.

From the point of view of performance characteristics, operation features and combat capabilities, the 2S34 Khosta self-propelled gun is a modern and successful replacement for the well-deserved, but aging 2S1 Gvozdika installation.

But it personally seems to me that the rejection of 122-mm guns with D-30 ballistics in favor of 120-mm combined guns of the 2A50 type was the deepest mistake of our Ministry of Defense.
Yes, "Khosta" is a very good CAO, but despite the much later completion date of the development and the presence of a number of undoubted improvements, it failed to achieve the performance characteristics of "Carnation". In terms of the totality of characteristics, it, alas, is not an adequate replacement for 2C1.

[Mikhail Maslov]

I completely agree with you. As an addition, yes, but not on the basis of the old chassis and cabin. That is, the self-propelled guns "Vienna", which they did not accept, but created such a monster.

As I understand it, 122mm caliber guns will gradually go into oblivion, they will be replaced by 152mm and 120mm.

[Bogalex]

This process has been going on for a long time. Back in the USSR, they tried to create 152-mm regimental-level guns under the code "Pat". But it didn't work out.
With the decrease in the strength of the RF Armed Forces in the 2000s, it became possible to simply replace the existing regimental 122-mm 2S1 and D-30 with the 152-mm "Acacias" released after the disbandment and downsizing of units and formations. But the battalion link was supposed to be "Vienna" and "Hosta". I emphasize that they were not going to replace the Gvozdik, but instead of the armament of mortar batteries of motorized rifle (tank) battalions - 2S12, 2S9, 2S14-1, etc. The 82 mm caliber was generally supposed to be left only for the Airborne Forces and mountain units.
But something, especially after February 2022, "went wrong"...

[Dimax-nemo]

There were no regiments, and the brigades had to arm themselves "like people." In the Soviet understanding - now not even "divisional", but "army" artillery. There was no place left there for either the D-30, or for Pat, or for Nona-SVK / Vienna / Hosta. And for the battalion, the toad strangled the last three.

[Mikhail Maslov]

I completely agree with you. As an addition, yes, but not on the basis of the old chassis and cabin. That is, the self-propelled guns "Vienna", which they did not accept, but created such a monster.

[Yaroslav Tekkel]

For the first time it became known that such equipment is also involved in measures to demilitarize the enemy.

I wonder why I have known about this since March, when the Armed Forces of Ukraine won the first "Khosta" and posted photos?

[leit]

It seems like a good tool. They knew how to do it, but now the Motovilikha plants went bankrupt and put up for auction and the final price is only 830 million rubles for the entire enterprise.

[steeldrone]

There are 2 questions:
1. Until now, starting from the 30s of the last century, the weight of "universal" guns ultimately lagged behind "clean" samples.
Does a gun + howitzer + mortar in one bottle really work well and justify itself?
2. 120mm should carry less explosive than 122mm - is it worth it?

[Sergey Aleksandrovich]

120-mm (SAU Nona) 3OF49 explosive weight - 4,9 kg,
122-mm (D-30 howitzer) 3VOF80 explosive weight - 4,31 kg.

And on the first question, there is an assumption that the barrel for ammunition with ready-made rifling will be much more durable, and the ammunition is cheaper.

[Dimax-nemo]

It seems that they wrote that they refused to "modernize" - it swayed too much when firing. In general, this only made sense for the unification of calibers, Gvozdika shoots further.

[Sergey Aleksandrovich]

They even abandoned the 2S31 Vena on a more stable BMP-3 chassis. They considered the tracked chassis for artillery and mortar installations too expensive. Perhaps they will begin to mass-produce the Phlox CJSC on a wheeled chassis.

[Dimax-nemo]

To them, the barrel itself with rifling, recoil devices and loading from the breech seems "too expensive" for the battalion.

[barbiturate]

When we wait for the elementary: self-propelled guns or MLRS are connected with the drone into a single system, the commander sees from the camera of the drone, a target has appeared - if it is moving, then the UAV will illuminate with a laser or give a lead point, stationary - the GPS coordinates will immediately throw off and after 10-20 seconds a shot, a guided projectile, let it be actively reactive, let the range be 60-70 km ... well, what's technically difficult? UAV? Communication channel with video skip to monitor? GPS detection, laser illumination? Make a projectile?
These howitzers would be scary 2 orders of magnitude stronger than the enemy, otherwise there are a lot of videos: an UAV is following the enemy, the enemy has already submerged, unloaded and has long been dispersed through the bushes in the trenches, then after 5 minutes bang bang, you can see anywhere and to no avail

[wladimirjankov]

12 km is now not enough for a 120 mm gun. For them, it is necessary to make guided missiles to increase the range and improve accuracy.

[Dimon-chik-79]

A few dozen? .. yes. this is all to that statement about more than 70% of new technology!
But the question here is different, but how does this installation meet the requirements of today? In my opinion, this instance was late for the troops for at least three decades! And then there are questions to the 120mm gun how much
its power is enough, and to the lack of automatic loading, i.e. to the rate of fire and to the sight, i.e. to accuracy.
It seems to me that the 120 mm artillery mount itself no longer meets the requirements of current realities. Even from the fighting in Ukraine, it can be seen that 152-155mm caliber guns have come to the fore and the one who has added accuracy to this caliber, relying on modern digital control systems and high-quality intelligence, has the advantage, and the creation of so-called "lunar landscapes" only devastates warehouses, overload logistics and production!
By the way, it's not entirely clear, so what changes "Host", "Nona" or "Carnation"?
No, if something 120 mm comes to the Airborne Forces to replace the Nona, which is made with all the consequences based on the BMD-2, but with a fast automatic loader and with a first-class modern sight, then this is a completely different matter. After all, the reformatting of the Airborne Forces with their cardboard combat vehicles is long overdue! It may be true that the amphibious equipment should be left to the paratroopers, and the airborne landing to the MTR units ?! Motorized riflemen, of course, need equipment with greater security (at the level of the Kurganets, but less expensive something like the BMP3 Dragoon with a rear ramp and to hell with this waterfowl) and support for mobile gun systems of 152mm caliber and more, which also have high accuracy and rate of fire.

[AlexisT]

Honestly, this is the first time I hear about the presence of 120-mm artillery in our army. Where did you put 2 mm?!

[Tank destroyerSU-100]

There are two questions. First: what is the maximum firing range of the 2S34 compared to 15300 meters for the 2S1? Second: what is the weight of the ammunition and its explosiveness compared to 21,76 kg of the weight of the 122-mm OF-462 projectile and 3,675 kg of explosives in it?
If the range is significantly lower, and the weight of the projectile and explosives is significantly less, then what is the deep meaning of such a replacement? We replace the 122-mm gun with a system that has less firepower, for what? Only the pursuit of the notorious air mobility in the light of the notorious fight against the notorious "international terrorism"? So after all, it is already completely clear that the war with the "barmaley" can no longer be considered the main task of the army. I had to face fortification a la "Mannerheim Line". And lightweight systems, sharpened for the fire destruction of openly located targets, are no longer in honor.

Quote: Amateur

All these "Khosts", "Kudepstas" and other "Armata" are worthless in modern warfare if they aim with the help of an artillery compass, which was used by the grandfather of the current artilleryman.
TV "Zvezda" regularly shows in the news about the SVO how these compass are used to aim artillery. At least they didn’t show them, they didn’t disgrace themselves.

It sucks not to know and forget that the compass is used not for aiming, but for orienting the guns in the main direction at the firing position. As well as for orienting observation devices. The aiming of the guns is carried out along the horizon using the panorama.

[George Sviridov]

Host class, as a matter of fact it is necessary to redo all 122. Leave only in the airborne forces, mountain brigades, and maybe the marines have towed (landing), self-propelled guns all converted into hosts ...
Minus 1 caliber is already good, plus high-precision 122 is almost never produced, concentrate on 120.
