Tass

Self-propelled anti-tank gun 2C25 "Sprut-SD" was created in the early 90s. On an extended (for two rolled rolled), the base of the military machine of the landing of the BMD-3 joint-stock company "Volgograd Tractor Plant", and the artillery part to it is at the Artillery Plant N9 (Yekaterinburg). Unlike the towed artillery system "Sprut-B", the new SAU received the name "Sprut-SD" ("self-propelled", "landing").

SAU 2C25 Sprut-SD - Video

Initially intended for the Airborne Forces and designed for parachute landing with the crew from the IL-76 military transport aircraft, now the gun is offered and marine infantry in order to provide anti-tank and fire support during landing operations.

One of its first ideas was held on May 8, 2001. On the Tank Polygon "Prudbuby" of the North Caucasus Military District for representatives of the power ministries of Russia and the Foreign Military Diplomatic Corps from 14 foreign countries of Southeast Asia, the Middle East, Africa and South America.

Purpose

125-mm Self-propelled anti-tank gun 2C25 "Sprut-CD" is intended for damage to technology, including armored, and alive enemy power under action as part of units of land and airborne troops, as well as marines.

Externally, it looks like a regular tank and combines the capabilities of the landing the floating martial car of the landing with the main combat tank. Externally, the "spruct-sd" is no different from the usual tank and has no analogues abroad.

Key Features

According to experts, the new SAU, in appearance and firing power, is comparable to the tank, characterized by the maneuverable capabilities of the landing BMD-3 and has no analogues abroad. In addition, the "Sprut-SD" is equipped with a unique hydropneumatic chassis that allows a combat vehicle smoothly and quickly moved to off-road at speeds up to 70 km per hour, which significantly improves the conditions for maintaining fire in motion.

In addition, the Sprut-SD is able to overcome water obstacles at a speed afloat to 10 km per hour. This was confirmed by the tests in the North Sea, when at a storm up to 3 points BM confidently led fire on the appointed goals. The car can land with cargo ships on the water surface and independently returns to the ship. The marked and other qualities in combination with the circular rotation of the tower and the stabilization of weapons in two planes allow you to use the "spruct-sd" as a light floating tank.

General device

BM Case is divided into control unit (front part), combat compartment with tower (middle part) and motor-transmission compartment (stern).

In a marking position, the machine commander is located to the right of the driver's mechanic, and the gunner 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. Powder sight with laser range finder stabilized in a vertical plane.

Armament

125 mm Smooth-bore Gun 2A75 is the main armament of CAU "SPRUT-SD". The gun was created on the basis of a 125-mm tank gun 2A46, which is installed on T-72 tanks, T-80 and T-90, when installed on a lighter chassis, the gun was equipped with a new-type anti-reflective device that provides a rollback of no more than 700 mm. Installed in the combat department, a smooth-borne gun of high ballistics is equipped with a computerized fire control system from the workplaces of the commander and aneck, which are functionally interchangeable.

As an auxiliary armament of SAU "SPRUT-SD" is equipped with a paired with a gun of 7.62-mm machine gun with ammunition of 2000 ammunition, cut into one tape.

The gun without a muzzle brake is equipped with an ejector and thermal insulation casing. Stabilization in vertical and horizontal planes allows you to fire 125 mm ammunition of separate-gilz charging. Sprut-SD can use all kinds of 125-mm domestic ammunition, including armor-piercing podkalibernochy shells and tank ptthys. In the ammunition of the gun (40,125-mm shots, of which 22 in the machine charging) can include a laser guidance projectile, which ensures the defeat of the target for a distance of up to 4000 m. The gun can fire on the way with an excitement of up to 3 points in the ± 35 sector Grad., Maximum rapidity - 7 shots per minute.

Horizontal carousel type gun charging machine set behind the tower of the machine. It is a set of nodes and mechanisms - a rotating conveyor with 22 ready-to-use shots, a chain mechanism for lifting a cassette with a shot, the removal mechanism for the removal pallets with a catcher, a chain rate of shot of a cassette in a cannon, drive of the hatch cover of the sleeve and a movable tray, electromechanical Breakie stopper on charging charcoal, control unit. Cassettes, with separately placed shells and charges placed in them, installed in the conveyor of the charging machine at an angle equal to the corner of the gun charge. When charging, a projectile is first supplied to the executive part of the toilet, then a throwing charge in a semi-portable sleeve-carriage. In case of failure of the charging machine, it is possible to charge guns manually.

To ensure an enlarged rollback, the charging machine has an extended frame of the cassette lift. The capture and removal removal removal mechanism provides the ability to temporarily overlap the rear side of the end of the bundle of the gun in it. This allows, with the subsequent movement of the shooting pallet, the cleaning system is purified by air the branches of the guns and the crew workplaces using the rotating device. In the lower part of the combat department, a driving machine-rotating axis is installed around the vertical axis, allowing the crew members to move inside the car from the combat compartment to the control unit and back along the sides of the case.

Fire control system

Includes aiming flooring complex (night and day sights with vertical stabilization of the field of view, a digital ballistic calculator, a laser rangefinder); The commander's sight combined with a day / night sight function with a laser rangefinder and a stabilized field of view in two planes, as well as a guide to the target of the controlled rockets 9k119m; A set of sensors for automatic input of the amendments, taking into account the parameters of the atmosphere, charge temperature, wear and curvature of the trunk, etc.

The computerized fire management system from the workplace of the commander provides observation of the terrain with a stabilized field of view, the search for the goal and the target designation using the optical system of the commander sight; Combination in the commander's sight of the start and control functions of a rocket with a sight shooting artillery shells; duplication of the ballistic computing device of the instrument complex of the gunner; autonomous inclusion and control of guidance drives and gun charging machine; The operational transmission of the control complex from the gunner to the commander and vice versa.

Power installation and chassis

It has a lot in common with the BMD-3, the base of which was used in the development of SAU 2C25 "Sprut-SD". Multi-fuel diesel engine 2B06-2C with a maximum power of 510 kW is styled with a hydromechanical transmission, a hydraulic transmission mechanism and power selection for two water meters. Automatic gearbox has five transmissions forward and as much reverse gear.

Individual, hydropneumatic, with a clearance-driver changeable with a mechanic-driver (for 6-7 ° C from 190 to 590 mm) chassis suspension provides high permeability and smoothness. The chassis for each board includes seven single-sized rubber rinks, four supporting rollers, the leading wheel of the rear and the guide wheel of the front location. There is a hydraulic mechanism for tensioning steel, double-grade, laid gearing tracks with a rubber-metal hinge that can be equipped with asphase shoes.

When making a march to 500 km, the car can move along the highway with a maximum speed of up to 68 km / h, on dry dirt roads - at an average speed of 45 km / h.

Two water vessels allow SAU 2C25 vehicle by water at a speed of up to 10 km / h. To increase buoyancy, the support rollers with closed air chambers and powerful water pumps, pumping water from the housing, are installed. The car has good nautical qualities and can effectively operate afloat, including leading aiming fire in the front sector of shelling at 70 degrees., With an excitement of 3 points.

In addition to the specified standard machine equipment, the machine includes a mass lesion protection system and a set of night vision instruments.

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.

The army of many countries of the world recently pay special attention to legogencies of a legitimized combat technology as the basis of rapid response forces. The fight against international terrorism and operations to maintain peace in local conflict zones demanded the creation of highly mobile and functionally flexible "combat systems of the future".

In this regard, according to foreign specialists, it is Russia who has the greatest opportunities in the field of creating a legogencies of a legogencies of a palace technique. The Armed Forces of the Russian Federation are already equipped with effective samples of easy (up to 18 tons), highly expensive, air transportation armored vehicles capable of performing tasks autonomously, in the separation of the main forces and rear parts, as well as in any conditions (including in difficult and remote areas, in the mining terrain, in the conditions of the desert and on the coast).

In addition, according to specialists, this class of combat vehicles has significant export potential. It is these machines that can be used as a basis for equipping the mobile component of the armed forces and special services of any state.

The legality of this opinion confirms SAU "Sprut-SD". After her demonstration at the landfill, many military attache recognized that in combat and operational capabilities, it exceeds all existing foreign counterparts. So, no car in the world can be used in the mountains at an altitude of up to 4000 meters, change the clearance of 400 mm, swim with the sea excitement to 3 points, go away and go from the water to the landing ship and landing along with the crew.

Tests and adoption

In 1984, a tactical and technical task was approved for the creation of a 125-mm paratable self-propelled anti-tank gun "Sprut-SD", on October 20, 1985, the decision of the military-industrial commission of the Council of Ministers of the USSR was officially launched the development of a new 125-mm SPTP for the Airborne Forces of the USSR. In February 1986, the development of means of landing for SAU 2C25 was launched. Means of landing obtained the designation of P260 and were created on the basis of parachute reactors of P235, intended for landing BMP-3. In the period from 1990 to 1991, state tests of SAU 2C25 were conducted. However, the tests of the P260 system revealed its disadvantages, the main of which were: complexity in operation, the high cost of manufacture, the complexity of the cassette block of the parachute-reactive brake engine. On May 30, 1994, by the decision of the Air Force of the Russian Federation, the Airborne Department of the Russian Federation and the developer of landing - the Moscow plant "UNIVERSAL" - the development of parachute reactive means of landing P260 was canceled, the development of a free entry system of P260m "Sprut-PDS" was launched. In 2001, additional tests of SAU 2C25 were conducted. On January 9, 2006, the order of the Minister of Defense of the Russian Federation, the self-propelled anti-tank gun 2C25 was adopted by the Russian army.

Serial production and modifications

In addition to the main version of SAU "SPRUT-SD" for the Airborne Forces, a variant of the 125-mm self-propelled anti-tank gun for the land forces was also developed, which received the name "Sprut-SS". Unlike SPTP SPRUT-SD, SAU "SPRUT-CES" was not able to land targeting, and as a basic Multi-purpose chassis "Planer", developed in the design bureau of the Kharkov Tractor Plant and intended for replacement in the land forces of tracked tractors MT -LB and MT-Luba. Work on the creation of SPTP "Sprut-CER" on the manufacture and testing of prototypes did not advance. In addition to the caterpillar option, for the land forces, under the name "Sprut-K", a variant of placing the combat department of SAU 2C25 on the wheelbase of the armored personnel carrier BTR-90 was also worked out, however, and this option was not adopted by the Russian army.

Evaluation of the car

Despite the fact that the self-propelled gun 2С25 refers to the class of anti-tank SAU, in its capabilities and the spectrum of solved tasks "Sprut-SD" is a slight tank. The reason why SAU 2C25 is initially classified as a anti-tank gun, it was the fact that the ordered control of the experimental design work was a grain that did not have authority to develop tanks. The main representatives of the previous generation of this class of technology are lightweight PT-76B tanks and an object 934. The test results of the Tank 934 tank showed that it was superior to the PT-76B tank in both weapons and waterfrost. In turn, SAU 2C25 combines the firing power of the main tank with the high characteristics of the maneuverability and the passability of the light tank, which allows it to be a modern replacement for the PT-76 tank in the divisions of the marines and the ground troops. The use of SPTP SPRUT-SD in airborne divisions allows us to solve the task of dealing with the tanks of the enemy.

Tentization of SAU 2S25 Sprut-SD

You have no rights to post comments

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.

2C25 "Sprut-SD" ("Object 952") - the Russian self-propelled anti-tank gun (SPTP), which refers to the category of sau. It is a slight airborne floating machine, the main purpose of which is the destruction of armored rolling purposes. The machine can be used to destroy defensive structures and supporting points, also for the implementation of fire support for the landing units of marines and airborne courses at any time of the day.

As a chassis for "SD-SD", the base of the BMD-3 extended by two rollers is used, equipped with a hydro-pneumatic chassis of a new design. The SPTP is able to handle independently with cargo ships, lead fire on the way and return back to the landing vessel.

BM has a classic layout. In front of the car there is a control department, then a combat compartment with a gun tower is underway, the motor-transmission compartment is located in the stern part. When making a march, the router is located to the left of the driver mechanic, and the commander is to the right.

Each of the three crew members have individual observation devices that operate in the "Day - Night" mode. The new SEO on SPTP consists of a sighting complex of a gunner combined by a commander stabilized in two planes and combined with a laser rangefinder, a kit for guiding the UR, which are included in the 9k119m complex, sets from several sensors that provide automatic input to other SPTP equipment.

The SUO, mounted at the workplace of the commander, is fully automated and provides him with circular observation of the terrain, stabilizing the translated image in two planes, the search for targets and the issuance of target designations using the optical system of sight of the commander. In the 2C25 project, the task of combining two functions in the commander of two functions is solved: Start and UR management, organization of aiming shooting by artillery shots.

To increase the reliability, the ballistic calculator installed in the instrument complex of the gunner is duplicated. Backup control is also provided for a gun charging machine (control of guidance and autonomous inclusion drives). All this allows you to quickly transmit the management of the Commander or Petrol Complex.

Chassis and power plant SPTP are much identical to the prototype ("Object 934"). Engine - multi-fuel diesel. There is a power take-off box for two water commentors. The automatic transmission box has five transmissions for the front and reverse. Hydropneumatics, individual for each trading, for a few seconds it allows you to change the clearance "Sprut-SD", and the suspension design gives a high smoothness of the stroke and permeability.

To increase the buoyancy design of the Svetp, equipped with support rollers having closed air chambers, pumps for pumping water. The car has sufficiently high seaworthy qualities, is able to effectively act on the way. For example, by excitement by force in 3 spruct-cd scores, aiming fire may lead in the front sector of the shelling (± 35 °). The regular set of cannons also includes a system of collective protection against the OMP and several sets of night vision instruments.

The design and mass boiler characteristics of the SPTP allow it to deliver it to the fighting area of \u200b\u200bboth aircraft of military transport aircraft and landing ships. It can be asphaned by a parachute (without crew and with it). The machine can independently overcome water obstacles without prior preparation for their forcing.

Artillery shells used for shooting, after a shot can be guided on a laser beam target using a commander sight. Real-time target data is formed by a laser rangefinder of the gunner and enter the ballistic calculator. The main weapon of SPTP is a smooth-bore tank gun, the prototype of which was a gun 2A46, used to armared the main combat tanks of Russia. Since the SVTP chassis is much easier than tank, a number of major changes made a number of serious changes. An ejector was installed, a new anti-type device, a thermal insulation casing. The muzzle brake is absent. The gun is structurally stabilized in two planes and is designed to run a fire by any type of ammunition of a 125 mm caliber, belonging to the shots with separate-guilty charging. The projectiles inscribed on the laser beam are capable of hitting the armored properties of up to 4 km. Maximum rapidity is 7 shots / min. The gun is charging using a horizontal charging machine, which is installed behind the artillery tower. The machine is equipped with 22 artillery shots, fully ready for immediate use. If the machine fails, the cannon can be charged manually. With a gun, the PKT machine gun (SPTP auxiliary weapon). For protection, a smoke grenade starter is used.

The driving automatic conveyor rotates around the vertical axis. It is mounted at the bottom of the combat department. This allows SPTP crew members to move from the first to the second branch and back along the sides. Sprut-SD is equipped with a system of forced ventilation of the crew and execution of guns.
