Sprove self-propelled installation. Self-propelled anti-tank gun "Sprut-SD. Maybe you will be interested

In the 80s, NATO has begun intensive buildup of their weapons. It became a push for the Central Research Institute for the creation of a new concept for the development of military equipment for the USSR. In order to create an effective instrument capable of confrontation of NATO tanks, in the 90s, specially for the Airborne Forces of Russia, Volgograd Tractor Plant, was developed by a self-propelled anti-tank gun 2С25 "Sprut-SD".

About authors Development

"Sprut-SD" 2С25 is a Russian avidiate self-propelled anti-tank gun. A. V. Shabalin became the main designer who was engaged in the manufacture of chassis. The 125-millimeter gun 2A75 to the Sprut-SD 2C25 was developed by V. I. Nedkina. Work on the creation of this Russian anti-tank weapon was carried out in the TsNII of accurate engineering.

Getting started

In 1982, on the basis of the SAU 2C25 SPRU-SD layout, developed under the caliber of 125 mm. This has become a confirmation that using the nodes and aggregates of the landing machine, it is possible to create a new, very effective tool. The leadership of the CNII to the point decided that for the design of a easier chassis, a light tank "Object 934" can be used, which was equipped with a lightweight 100-millimeter rush gun with a charging automation, designed for 19 shots.

One of these tanks has become the basis for creating a sample of a 125 mm tool. The upgraded tank "Sprut-SD" has now equipped with a smooth-bore 125-mm cannon. In the process, a classic tower circuit was used. In addition, the designers were also considered options with weapons.

Testing

In 1984, the Sprut-SD 2C25 was transported for experienced shooters to the Cube Polygon. The test results of the new SAU have shown that it is not inferior to tank guns in the adhesion, and the load acting on the crew and the gun itself does not exceed the permissible limits. On October 20, 1985, the Military Industrial Commission decided to begin production of a 125mm gun for "Sprut-SD" 2С25.

What difficulties are the developers faced when creating targeting funds?

P260 tools that ensure the landing of the self-propelled installation, a number of disadvantages have shown during the test:

• their production was expensive;
• the use of P260 funds turned out to be complex.

As a result of work on parachute and reactive funds, it was discontinued, and the P260 was taken by the Formant setting system, which received the designation of P260 M.

What is "spruct-sd" 2c25? Design Description

It is a combat armored tracked floating machine that uses a powerful artillery-missile complex as weapon.

SAU consists of three parts - enclosures:

• The front is a clause that provides the control of the machine "Sprut-SD" 2S25. The photo below presents the features of the structure of self-propelled installation. This building is designed for three people: the commander of the self-propeller, the gunner and the driver-mechanic. In the roof of the crew combat vehicle there are built-in observational devices with day and night vision.

• In the middle case there is a tower of installation. This unit is combat. The sight designed for the older crew is a combined design: the sphere of its activity is distributed into two planes due to alignment with a laser sight. The guidance of a 125 mm projectile is provided with a laser beam.
• The rear is considered the place of the motor-transmission office.

Workplace arrangement for commander

At the workplace of the main crew, the design of the artillery installation provides for the presence of such devices:

• day monocular periscopic sight 1A40-M1 having a stabilizing field of view;
• night optical electronic complex TO1-CO1R;
• a laser rangefinder, with which the commander measures the distance to the target and produces a proactive angle during the shooting of a moving target;
• information channel with which guidance and start of a managed rocket is carried out;
• a duplicate ballistic and aiming device, which is used by the gunner;
• special console that performs autonomous control of automation during charging;
• drives providing the operational link between the commander and the nodder.

What tasks do the crew commander?

The main in the group with the help of night and day vision sights performs observation of the terrain. The commander of this self-propelled artillery installation, regardless of the gunner, can perform a targeted shooting of both machine gun and from the gun. This feature is provided at the expense of a computerized fire management system: if there are source data with a tank ballistic calculator, an automatic input of angles and proofs is carried out. At the expense of this function, the commander does not need to perform a rejection using rangefinder and targeted brands. The commander can freely perform shooting.

How is the tool created by the created?

Anti-tank - to such a class of guns was a combat machine "Sprut-SD" 2С25. The appointment and spectrum of the tasks performed by it were reduced to the fight against enemy tanks. Previously, this task was performed by such tanks as PT-76B and "Object 934". They were replaced with the advent of 2C25 "Sprut-SD". Fire support combat machine, unlike other lightweight tanks, has a higher firepower. The maneuverability and permeability of the new SAU corresponds to the indicators characteristic of the combat guns of light tanks. Sprut-SD is a modern and more advanced version of PT-76B.

In what conditions is operated?

"Sprut-SD" is able without refueling to overcome distances at least 500 kilometers. SAU transportation is carried out by military transport aircraft. Also for this purpose, landing ships can be used. For setting the installation, its developers provide landing and parachute methods. The crew of the combat vehicle at the same time is in its cabin. Having a high specific power, the Sprut-CD is suitable for conducting hostilities in both high-mountainous terrain and hot tropical climates.

SAU is able to withstand the high-filadged enemy technique, its fortified reference points and a vibrant strength. Overcoming water obstacles is possible, provided that the excitement does not exceed 3 points. Working on the water, artillery installation can at the expense of the installation equipped on the chassis, the installation is provided with water methods with the diameter of the working wheels 34 cm and support rollers. In the design of SAU there are closed air chambers. When water gets into the case, the pumping is carried out with a powerful water pump. Being afloat, "Sprut-SD" can lead shooting.

After performing its combat mission, the Sau is adapted to carry out an independent load from the water surface into the landing ship.

Especially for work in the snow-covered area are used snow farters and asphalt shoes. Sprut-SD is suitable for the terrain that has received radiation, chemical and biological infection. The safety of the crew provides protection against weapons of mass lesion.

Masked the combat artillery machine can with the help of a smoke curtain. For this purpose, the designers mounted on the feed sheet of the SAU brackets (2 pieces) tower, in which there are six grenade launchers 90V, using smoke grenades of 81 mm caliber.

For what purposes a combat was created?

Initially, SAU was designed to confront tanks, various armored vehicles and a vibrant strength. 2C25 "Sprut-SD" - a fighting machine of fire support - was intended only for the Airborne Forces. The task of the packed self-propelled artillery installation was to combat armored machinery in the enemy rear. Over time, it entered the marine infantry and special. The experience of using 2C25 showed that, interacting with the BMD-4 combat vehicle, equipped with a 100-mm gun and self-propelled FEDR "Cornet", "Sprut-SD" can be very effective not only in the rear of the enemy, but also in a direct combat clash, which The land forces of the Armed Forces of Russia are carried out.

In the interval from 2001 to 2006, after the additional tests of the Russian Federation, the combat machine "Sprut-SD" 2S25 was obtained in their location.

Main characteristics

The weight of the combat vehicle is 18 tons. The crew consists of three people. The stroke reserve is 500 km. The chassis consists of seven rubberized support rollers, six single rubberized rollers, a leading and guide wheels, steel double-grade caterpillars, in which rubberometallic hinges, and asphalt shoes are used. The SAU length with a cannon is 9.77 meters.

The combat vehicle is equipped with a six-cylinder four-stroke opposite diesel engine with a superior and direct injection of fuel for which liquid cooling is provided. 2V-06-2C - engine brand installed in "Sprut-SD" 2С25. Technical characteristics of the engine allow SAU to develop speed from 45 (medium) to 70 km / h.

SAU is equipped with anti-film armor. The frontal part is able to withstand direct hits of 23-millimeter shells from the distance to Polkilometer. In the process, the manufacture of armor for the combat vehicle was used aluminum alloys (for the CAU and its tower hull). The frontal part device was performed using steel linings. For combat vehicles, R-173 radio stations are provided for R-174 negotiations.

Aviation landing of the combat vehicle is carried out from IL-76 aircraft (models M and MD), An-124. The use of external suspension for the MI-26 helicopter also allows you to successfully carry out the direction of self-propelled installation "Sprut-SD" 2С25.

The armament of the Army of the Russian Federation has enriched a SAU equipped with a single smooth-bore cannon 2A75 and parsed with her machine gun of the PKT brand. The combat kit of the main tool 2a75 is designed for 40 shots. Mechanized styling contains 22 ammunition. Additional - 18. Machine gun caliber: 7.62 mm. One contains 2000 cartridges.

What projectiles are used?

The combat vehicle amplifier contains shells that make it possible to perform four types of shots:

• Collective-fugasny (20 shells).
• Armor-piercing (14 pieces). After performing the shooting of armor-piercing cut-free shells from a two-kilometer distance, a homogeneous armored steel can be triggered, the thickness of which does not exceed 23 cm.
• Cumulative shells (6 pieces). Punch homogeneous steel armor with a thickness of up to 30 cm.
• Equipped with armor, the thickness of which exceeds 35 cm.

Installation of the main equipment setting

Using the 2A46 tank gun and its modifications, 2C25 designers created an advanced 125-millimeter smooth-bore cannon 2A75. In order to reduce the power of resistance to rollbacks during shooting, the presence in the installation of a special muzzle brake was planned. But as a result of these works, there were problems with the impact of the guns, which were solved by increasing the length of rollback to 74 cm. Additionally, a hydropneumatic chassis suspension was developed, the mechanism of which absorbed the remnants from the recoil pulse.

The gun 2A75 is equipped with a charging automatic, which has a positive effect on the rapidness of the gun: 7 shots can be performed in one minute. This automation consists of:

• conveyor mechanism equipped with 22 cassettes;
• chain mechanism producing lifting cassettes;
• chain rate;
• the mechanism performing the removal from the combat part of the installation of the shooting sleeves.

Conclusion

The firing power of the Sprut-SD combat vehicle is not inferior to such tanks as the T-80 and T-90. High mobility both on land and on the water allowed SAU 2C25 to achieve the level of the BMD-3 combat vehicle. Due to the characteristics of the design - the capabilities of the tower in the SAU perform circular rotations and stabilization of weapons in two planes - "spruct-sd" can be effectively used as a light floating tank, which has not been created today.

The self-propelled artillery installation developed by Russian designers aroused interest among representatives of the Armed Forces of Korea and India.

Information about development

In the early 1990s, the Volgograd Tractor Plant, a new anti-propelled self-propelled gun 2С25, was created by the joint-stock company "Volgograd Tractor Plant" on the extended base of the BMD-3 combat vehicle. The artillery part for this machine was developed in Yekaterinburg Specialists of the Artillery Plant N 9, producing both tank guns and artillery caliber systems up to 152 mm.

Sprut's history leads from the "Object 934" developed in the late 70s, which was armed with a lightweight 100-mm rush gun 2A48 equipped with a 24 shots. The new light tank received a 125-mm smooth-bore tank gun 2A75, which can use the entire nomenclature of shots intended for the main combat tank, including a complex of managed rocket weapons. Given the need to install a gun on a lighter chassis, the specialists of the Artillery plant N 9 equipped the gun with the anti-reflective device of a new type.

Although the original self-propeller was intended for Russian airborne troops - it is designed for parachute landing with the crew on board from the IL-76 military transport aircraft, - currently it is also offered by marine infantry in order to provide anti-tank and fire support during landing operations . Unfortunately, at present, the Russian army does not have sufficient funds for the purchase of self-propelled artillery installation 2С25, but the interests of the Armed Forces of the Republic of Korea and India showed interest in it.

Firepower

In the front of the Self-propelled body, the control department is located, the combat compartment with the tower occupies the middle part of the car, in its feed there is a motor-transmission compartment. In a marching position, the machine commander sits on the right of the driver's mechanic, and the gunner is on the left. Each crew member has integrated observation instruments in the roof with day and night channels. The commander's combined sight is stabilized in two planes and is combined with a laser sight to guide 125-mm laser beam shells.

As an auxiliary weapon on the anti-tank self-propeller, a paired with a gun of 7.62-mm Machine gun with ammunition of 2,000 ammunition, equipped in one tape. Since SAU 2C25 was developed on the basis of the BMD-3, there are many nodes and aggregates of the undercarriage and the power plant of the base machine.

In combat department, a smooth-bore High Ballest Ballistic Caliber Ballistics was installed with a rollback size of no more than 700 mm, the gun is equipped with a computerized fire management system from the commander's workplaces and a member with the provision of their functional interchangeability, and with a stabilizer of weapons in 2 planes;

Reinforced parachute rating on BMD-4 with the support of self-propelled artillery on experienced tactical teaching. Dubrovichi Polygon, July 26, 2006

The fire capabilities of a parachute of the landing company, armed with modern BMD-4 combat machines and spruct-cd.

Complex "Stroy-P" (UAV), SPTP Sprut-C, -D and BMP-3M (BMP-4).

In the Pskov region at the Polygon of Strongs Red during the collection of artillery leadership of airborne troops, the possibilities of the newest self-propelled anti-tank gun (SPTP) "spruct-sdm-1".

The show of the possibilities of a promising combat complex was carried out with the participation of special and intelligence units of the artillery of the Pskov Division division of the Airborne Forces, which gave target designation and adjusted the fire of anti-tank funds using the OLD type "Orlan", radar complexes of "Aistenok" * and "Catolyatnik" **.

Self-propelled anti-tank gun 2c25m "Sprut-SDM-1" It is planned to replace the previous SPTP modification of 2C25, which is in service with the Airborne For more than 10 years.Spruct-SDM1 was first demonstrated at the Army-2015 International Military Technical Forum. Self-propeller is the development of the previous model 2С25 and after testing should be approved for airborne aircraft. According to military experts, this self-propelled installation is the best in the world and significantly exceeds all existing foreign analogues of this class.

"Afghanit" upset US stronger "Armat" \u003e\u003e

The main weapon - 125-mm gun 2A75M, capable of fire with armor-piercing subcaliber, cumulative, fragantive-fugasic shells and ammunition with a remote underproduction on the trajectory. In general, on the fireproof "Sprut-SDM1" corresponds to the level of the main Russian T-90 MS tank and is able to apply anti-tank armored arms for a distance of up to 5,000 m. In total, 2C25m has 40 shots, including 22 - in the mechanized wagging.

In addition to paired with a gun of the machine gun Pectm on a modernized car on the tower there is another such machine gun in a remotely controlled installation. Thus, the car commander got the opportunity to hit the revealed goals at the moment when the main weapon is already used by a gas-operator. Shared ammunition machine guns - 2 thousand cartridges.

Fire control system 2c25m also has a tank level. It includes the best in the world. operator's sight-operator "Pine-U" With television and thermal imaging channels, as well as a panoramic scope of the PCP commander with similar channels. Both targets have the ability to automatically accompany the target. In the event of damage to the main sights, an optical-electronic scope-dubler is used with a line of aiming stabilized in the vertical plane and autonomous power.

One of the main differences of the new car - This is a set of managed weapons (BUV) with a newest rocket that can destroy the tank with dynamic protection at a distance of 6 km.

The newest product is fully integrated with a digital fire control system (SWO), which not only increased the accuracy of the shooting "Sprut-SDM1", but also became possible shooting on low-tight and low-speed targets, such as opponent helicopters and unmanned aerial vehicles.

The new self-propeller received an upgraded rocket, which is shot through the gun barrel and created on the basis of the "Invo-M" shot. The cumulative charge is located in the nose part of the rocket and provides overcoming dynamic protection, including the embedded version. The main cumulative charge is striking directly. For the defeat of the fortified engineering structures, a rocket version with a fugasal combat part of thermobaric action was developed.

When modernizing at a 125-millimeter self-propelled anti-tank gun for "SPRUT-SDM1", a more perfect digital AUC with a combined gun gun with a thermal imaging channel of the night vision and the accommodation machine for targets was established. In addition, the commander "Sprut-SDM1" there was an opportunity to fire from an additional machine gun unit, including on the upper floors of buildings that dominate altitudes in mountainous areas and helicopters.

The modernized "spruct-sdm1" is unified by nodes and aggregates with the newly adopted military machine of the BMD-4M target. From this we can conclude that, as in the newest BMD-4M, the engine capacity of the engine is seriously increased, which significantly increases the mobility of the self-propelled gun both afloat and when moving around rough terrain.

Using the upgraded shooters of the type "Invo M" as part of the armament "SPRUT-SDM1", fundamentally new combat capabilities are obtained: the rocket firing range is 2.5 times higher than the distance of the response fire of any modern tanks, as the shell flies for 2000 m, and anti-tank The controlled rocket is 5,000 m. This allows you to win the fight before entering the effect of the effective fire of the enemy tanks.

The combat machine has a chassis information and control system that greatly facilitates operation, identifying faults. The newest communication complex has frequency modulation and technical masking. According to nodes and parts of the chassis, as well as on the Sprut-SDM motor-transmission compartment, the BMD-4M-4M martial vehicle is unified.

* Portable controlarian radar "Aisto" It is capable of providing reconnaissance of the enemy's firepoints, the calculation of the trajectors or rockets and the adjustment of the fire. Also, the complex allows you to control the airspace and watch the UAV.

Avax cheat in a whisper \u003e\u003e

At small distances, "Aisto" is able to track mortar shots by a caliber from 81 to 120 mm during flight flight, determining the trajectory of the flight and calculating the point of shot and falling the shell. The maximum range of detection of mortars is limited to 5 thousand meters. At such distances, "Aisto" is able to very accurately determine the ascending and downward trajectory of flight flights and calculate the coordinates of the enemymortar.

The minimum distance to determine the enemy mortars is 750 meters. At the same time, the target detection accuracy is several tens of meters and depends on the type of purpose. Calculation of the coordinates from where the shot is produced allows you to accurately apply confruders on enemy mortars and adjust your own fire.

The weight of the reconnaissance complex "Aisto", developed by the Almaz-Antey concern, is 135 kg. This is a bit for systems of this type and allows reconnaissions without much effort to move it both on a combat machine and manually with the help of three people. The set of modular system includes seven elements:

Support-swivel device with tripod,

receptionist with antenna,

Power Supply,

Primary information processing unit

Electrical unit

Radio station and control panel.

For a complete assembly of the "Aistote" modules and its preparation, only five minutes is required.The control panel made in the form of a laptop displays color information about the functioning of the device. Data on detected purposes are transmitted through the installed radio station of the centimeter range. "Aistotel "N. e has its own turning mechanism, but this deficiency is compensated by a 60-degree sector of observation in azimuth beam width. The definition of the enemy calculations is carried out by detecting the place of shot and calculating the trajectory of the projectile. The target detection range is from 2 hundred meters to 20,000.

**, artillery, reactive systems of salvo fire and the starting positions of tactical enemy rockets on a shot. In addition, to control the accuracy of shooting shock installations.Until recently, in the Russian army, the most modern complex of ground electronic intelligence was the PSNR-8 and PSNR-8M devices, which are preparing to give way to the latest electronic reconnaissance - the product "1-L277". His second name is "Cooked". Itused when fixing the direction of firing from the mortar, and even for finding drones flying at low distances from the ground. A distinctive feature of the product "1-L277" is the use of a phased antenna lattice, broadband pulse lfm signal to detect moving goals and removal of shells (min), as well as to detect fixed objects.

Russian special forces are equipped with a new AK-400 automatic machine \u003e\u003e

Military constructors added an automated primary data processing unit to the PSNR-8M station, freeing the operator of the scout station from the detection process of military objects and the living force of the enemy. At the same time, the distance of the electronic scout has significantly increased - its "hypodiness" increased to 30 km.

The PSNR-8M has only 500 hours of continuous operation, "1-L277" can work without breakdowns from 1500 to 2000 hours. That is, the reliability of the new scout rose 4 times.The PSNR-8 and PSNR-8M stations were 3 large drawbacks: the power of their impulse radiation was 1 kV, simply, the enemy was not so difficult to "throw out". The second disadvantage was the so-called mechanical scan of the locality, i.e. The antenna was rotated around his axis during operation. The engine that brought it into motion quickly failed, and it was necessary to change it. Therefore, the military issued a technical basis, which stated that these work techniques should be improved. Did not suit the military and the weight of the reconnaissance station. It was 62 kg, so its combat calculation was 3 people.

In the park "Patriot" for the first time will show the rockets "Granite" \u003e\u003e

The "chatter" carries out electronic scanning, due to which the antenna no longer need to rotate around its axis and change its engine from time to time. The weight of the station fell to 36 kg, and now its calculation consists of only 2 people. But the most important thing - the station practically turned into a "invisible", since its impulse radiation is now less than a mobile phone.

The resolution of the new reconnaissance station increased five times - with 50 to 10 meters. This made it possible to raise informativeness, and the operator got the opportunity to read targets in the column, i.e. distinguish individual goals. "PSNR-8M" squeezed a long strip on the screen, and the "Chatter" are separate items. Moreover, the new product has received an automated target recognition algorithms by criteria: man - car. By improving the new electronic scout, we can detect moving goals against the background of powerful reflections from the surface of the Earth.Thus, now the operator got the opportunity to see the movement of equipment and people on the screen of his monitor. The safety of the operator itself also increased due to the length of the cable connecting the monitor with an antenna, up to 30 meters. That is, in the case of an enemy attempt to destroy the station, the operator has more chances to remain unharmed.

A new product is able to detect live enemy strength at a distance of 6 km. The "Catolybnik" has a more complex signal with an intrapulse linear modulation frequency, which made it possible to reduce the peak radiation power to 8 watts. This sharply increased the stealth of this electronic scout.Some types of weapons are easily conjured with this station especially these machine guns, such as "Pecheneg »and" Cord " This allows it to be present in hostilities and at the same time be not noticeable if, of course, there is no optical observation.

As part of the creation and development of equipment for airborne troops, a new modification of the SPRUT-SD spripal gun was developed. To date, the renewed machine called "Sprut-SDM1" has been published on the test and passes all the necessary checks. In the foreseeable future, this self-gun can be adopted with the subsequent serial construction and supply of equipment for troops.

The existing armored vehicle 2C25 "Sprut-SD" was developed from the middle of the eighties, but due to various reasons was adopted only in 2006. The project meant the use of the existing caterpillar chassis "Object 934", which should be mounted a new combat department. SAU / SPTP "SPRUT-SD" is equipped with a smooth-bore canter 2A75 caliber 125 mm, which allows the use of the same ammunition as in the case of tanks available in service. Comparatively small dimensions and weight allow parachute towing technique.

Serial production of the Sprut-SD machines was conducted from 2005 to 2010. After that, it was decided to suspend the assembly of new techniques before the new project of modernized self-propelled. The new project of the renewed self-propelled gun was obtained 2C25M "SPRUT-SDM1". Its development was engaged by specialists of several enterprises from the concern "Tractor Plants". The task of this project was to increase the main combat characteristics through the application of a number of new equipment, first of all, other target devices and fire management tools. In addition, the revision of the existing chassis with the wide use of existing components and aggregates, aimed at maximizing the unification with the other technique of airborne troops was proposed.

As part of the modernization of self-propelled, it was decided to preserve the existing armor units. The housing and the tower of the original and modernized machine almost do not have differences. Applied modifications affected only some details and are connected only with the need to apply new nodes. The overall architecture, layout and other features of the car, however, did not change.

The most notable external difference between the SPTP "Sprut-SDM1" from the basic "spruct-SD" is the use of a new chassis. In order to simplify and reduce the simultaneous production of several samples of equipment for the Airborne Forces, it was decided to equip the self-propelled for the chassis, based on the aggregates of the Battle Machine of the BMD-4M. It is noteworthy that such a unification does not have a significant impact on the general parameters of the new car chassis. After updating, the self-propeller receives seven support rollers of small diameter with individual torsion suspension and hydraulic surfactants on each board. The ability to change the clearance due to adjusting the suspension parameters.

Also, in the composition of the undercarriage, there are feed leading wheels of the valve engagement, the front guides with the tension mechanism and several supporting small-diameter rollers designed to hold the upper branch of the caterpillars in the correct position.

The unification of the newest equipment for airborne troops also affected the power plant and transmission of the new self-propelled anti-tank gun. The SPRUT-SDM1 machine receives a new diesel engine of the UTD-29 capacity of 500 hp. Instead of the initial 450-strong 2B-06-2. Also, self-propeller receives a transmission borrowed from the existing target of the landing. Such refinement to some extent increase the specific power of self-propelled and, as a result, should have a positive effect on its mobility.

Noticeable refinement within the framework of the modernization project, a combat department was subjected. According to available data, SAU / SPTP SPRUT-SDM1 receives an updated fire management system with a number of new systems and targeted equipment with elevated characteristics. Now the machine has combined sights with television and thermal imaging channels, allowing weapons to apply at any time of the day. Also provides for an automatic support for targets that increase common combat characteristics.

New radio electronic equipment of the updated machine includes communication tools integrated into a unified tactical control system, which allows the crew to transfer data about various purposes to other machines, as well as receive targeting and other information. Such equipment is intended to increase the effectiveness of the joint combat work of several self-propelled.

Due to the updated fire management system, Sprut-SDM1, retains the possibility of applying an existing ammunition nomenclature. In addition, compatibility with programmable explosives of the remote bending on the specified area of \u200b\u200bthe trajectory is provided. Also, self-propelled crew can use controlled missiles of several types, launched from the barrel of the main tool.

The "main caliber" of the machine remained the same - 125-mm gun 2A75, which is the development of the 2A46 tank system. The gun with a length of 48 caliber barrels is installed on the stabilized system and can be guided in a horizontal plane in any direction. The elevation angles vary in the range from -5 ° to + 15 °. The tool is equipped with a charging machine, self-feeding the intersection of the desired type in Kamor. Amusement "Sprut-SDM1", as in the predecessor, consists of 40 shells of various types.

The new project implies the strengthening of additional machine-gun weapons. A 7.62 mm mounted molding of a 12.62 mm duct is added to the 20,62 mm PCT, mounted on a remotely controlled combat module. The module is proposed to be mounted in the aft of the tower, the management of them should be carried out from the battlepoints. In the boxes for the combat module ammunition, 1000 rounds are placed. The presence of an additional machine gun makes it possible to improve the capabilities of the technique in self-defense from infantry and unprotected enemy machines, and the placement of such weapons on the remotely controlled combat module, in turn, sharply reduces the risks for the crew.

The modernized SPRUT-SDM1 self-propeller has a combat lot at 18 tons. The dimensions of the machine in comparison with the basic version did not change. Mobility also remained on the existing level. The maximum speed on the highway is 70 km / h. With the help of feed aquets, self-propelled can cross water obstacles at a speed of up to 7 km / h. Driving the machine must create a crew of three: mechanics - driver, commander and flooring operator.

The first prototype of the new SAU / SPTP 2C25M SPRUT-SDM1 was built last year. Concern "Tractor Plants" for the first time introduced this car to the general public as part of the exhibition "Army 2015". At the same time, the main features of the new project were announced and some characteristics of the updated car were named. At that time, modernized armored vehicles were considered as a replacement for existing equipment.

A few days ago at the polygon of the red (Pskov region), the collection of the artillery of airborne troops took place. The military orders of the Airborne Forces were able to exchange experience and learn the last in artillery. In addition, during the collection, a demonstration show of the new SPTP "Sprut-SDM1" with the conduct of shooting was held. The press service of the ministry reports that not only new self-propeller was used during the demonstration shooting, but also some auxiliary means. So, in providing shooting with the help of targeting and adjustment of fire, unmanned aerial vehicles "Orlan", as well as radar stations "Aistenok" and "Catolyatnik" participated.

According to reports, the self-propelled anti-tank gun of a new type is still tested and is not yet ready for the beginning of mass production in the interests of airborne troops. Nevertheless, the authors of the project are already building relevant plans. According to the domestic press, the Sprut-SDM1 machines should go to the series in 2018. Soon after that, the troops will be able to get new armored vehicles with increased combat characteristics. According to the latest reports, representatives of the Airborne Forces have already become familiar with the new self-propeller. This event, as well as the continuation of work on a new project in one way or another, accelerates the adoption of new techniques for weapons.

The development of a light tracked self-propelled plant with a 125-millimeter tank gun was ordered by Russian paratroopers at Kurganmashzavod OJSC. According to Izvestia, with reference to the representative of the Airborne Party, participating in the works, the new car must be packed and replaced by the artillery settings "Sprut-SD", from which the Airborne Forces refused in 2010, when after the parade of May 9 due to the fuel leakage burned one Such self-propelled artillery installation with anti-tank cannon. Having received a new car, the Airborne Forces will find a weapon to fight the American tanks "Abrax" and Israeli Ott "Merkawa," the publication writes.

Earlier it was reported that on May 9, 2010, after a passage along the Red Square, the engine caught fire from one of the Spruit-SD. Later, the car was recognized as an emergency hazard and decided to stop further purchases of the "spruits".

The decision to develop a new artist, was adopted in February 2013 by the Deputy Minister of Defense of Russia Yuri Borisov.

As reported by the publication, the new SAU will be created on the basis of the BMD-4 martial vehicle. Instead of a 100mm gun on the same platform, a 125-mm tank ARTSISTER 2A46M-5 will be installed, which, in particular, armed tanks T-90. The tool will be able to fire armor-piercing projectiles, including lead, and anti-tank missiles. The guidance system will include the thermal imager and the accompanying machine of the target, which is able to measure the range independently and calculate the trajectory.

The length of the new car will be a little more than seven meters, and the weight will be about 18 tons, that is, self-propelled installation will be able to transport Il-76 military transport aircraft and Mi-26 helicopters without any problems. The new artist should move around the water, and will also be able to overcome the rise of up to 35 degrees.

Light tanksTo which the new Sau will relate, becoming increasingly popular in the world's armies. Such machines are created in Sweden, Poland, China. A lightweight tank is required in mountainous areas, in swamps where heavy equipment does not have the opportunity to pass. It can be delivered by air, and the infantry immediately appears a combat vehicle capable of conducting powerful fire. The new self-propelled installation in the Airborne Forces will be needed not only to combat tanks, but also to destroy the shelters of the enemy, fortified buildings. When the long-range artillery can not hit the target, the new saau will destroy the direct vendor.

Self-propelled artillery installation 2c25 "Sprut-SD" (SD - self-propelled landing) was developed as early as early 1990s. 125-mm Self-propelled anti-tank gun 2C25 "Sprut-SD" is intended for damage to technology, including the armored, and the living force of the enemy under action as part of the units of land and airborne troops, as well as marines. Externally, the car is similar to the usual tank and combines the capabilities of the landing floating BMD with the main combat tank. SAU "SPRUT-SD" can be transported by aircraft of the BTA and landing ships, landing with a parachute way with the crew inside the car and without preparation to overcome water obstacles.

125-mm Smooth-bore Gun 2A75 is the main armament of the CAU "Sprut-SD", created on the basis of 125-mm tank gun 2A46, which is installed on T-72, T-80 and T-90 tanks. When installing on a lighter chassis, the gun was equipped with a new type anti-reflective device that reduces no more than 700 mm. The car with a length of about 7 m, a width of 3.2 m and height of 2.9 m has a mass of 18 tons, can develop speed up to 70 km / h, the stroke reserve is 500 km. Supplies 2C25 in troops began in 2008; A total of 24 cars received the airborne.
