Description
ZIS-30 (57 mm anti-tank gun) - Soviet light anti-tank self-propelled guns open type. Created by a team of developers of plant No. 92 under the leadership of P. F. Muravyov. Machines of this brand were mass-produced at artillery plant No. 92 in the second half of 1941 by open installation of the ZIS-2 anti-tank gun on the T-20 Komsomolets artillery tractor. In total, about 100 ZIS-30 self-propelled guns were produced, which participated in the battles of 1941-1942. and were well received by the troops due to the effectiveness of the ZIS-2 gun. However, due to the small number, breakdowns and combat losses, they did not have any noticeable impact on the course of the war.

History of creation and combat use
The shortage of anti-tank self-propelled units The Soviet Army began to experience already at the very beginning of the Great Patriotic War. In July 1941, the High Command issued a decree to develop self-propelled guns armed with a 57-mm ZiS-2 gun as soon as possible. At plant No. 52, a group of designers was urgently assembled, headed by engineer P.F. Muravyov, and a month later the serial assembly of the ZiS-30 self-propelled guns began. The car was a tracked tractor "Komsomolets", which housed the ZiS-2 anti-tank gun designed by V.G. Grabin. The engine was located in the aft part of the self-propelled gun, and in the front - the transmission and controls. The front hull plate also had a 7.62 mm DT defensive machine gun. In total, about 100 ZiS-30 self-propelled guns were produced, which were literally distributed piece by piece among the tank brigades of the Western Front. For the first time, these self-propelled guns were used during the Battle of Moscow, where they proved to be excellent, successfully destroying any type of German tanks and armored vehicles. However, over time, the shortcomings of the ZiS-30 were also revealed. The car was extremely unstable, the undercarriage was overloaded (especially the rear rollers), the armor also left much to be desired. In addition, the self-propelled guns had a small power reserve and a scanty portable ammunition load, which amounted to only 20 shells. Nevertheless, despite all the shortcomings, the ZiS-30 continued to participate in battles until the summer of 1942, when there were practically no vehicles left in the troops. Some of the machines failed due to technical breakdowns, the rest were lost in battle. However, due to their small number, the ZiS-30 self-propelled guns did not have any noticeable effect on the course of the war.
Here is the news today:
Artillery units of the Eastern Military District (VVO) received a batch of 203-mm Pion self-propelled artillery mounts.
This was reported to Interfax-AVN on Thursday by the head of the press service of the district, Colonel Alexander Gordeev. »Today, the Pion self-propelled gun is considered the most powerful self-propelled artillery mount in the world. Its main armament is a 203-mm cannon, weighing more than 14 tons. It is located in the aft part of the installation. The gun is equipped with a semi-automatic hydraulic loading system, which allows this process to be carried out at any elevation angles of the barrel,” A. Gordeev said.
He noted that in the development of the undercarriage of the installation, components and assemblies of the T-80 tank were used. “The self-propelled gun has an individual torsion bar suspension,” the officer specified.

On August 29, 1949, the first Soviet atomic bomb: both opposing groups began to possess nuclear weapons. With the build-up by both sides of the conflict of strategic nuclear weapons it became clear that an all-out nuclear war was unlikely and pointless. The theory of "limited nuclear war» with limited use of tactical nuclear weapons. In the early 1950s, the leaders of the opposing sides faced the problem of delivering these weapons. The main means of delivery were B-29 strategic bombers, on the one hand, and Tu-4, on the other; they could not effectively strike at the advanced positions of enemy troops. Hull and divisional artillery systems, tactical missile systems and recoilless guns were considered as the most suitable means.
The first Soviet artillery systems armed with nuclear weapons were the 2B1 self-propelled mortar and the 2A3 self-propelled gun, but these systems were bulky and could not meet the high mobility requirements. With the onset of rapid development rocket technology in the USSR, work on most of the samples of classical artillery was stopped at the direction of N. S. Khrushchev.

After Khrushchev was removed from the post of First Secretary of the Central Committee of the CPSU, work on artillery topics was resumed. By the spring of 1967, a preliminary design of a new heavy-duty self-propelled artillery mount (ACS) based on the Object 434 tank and a full-size wooden model were completed. The project was a self-propelled gun of a closed type with a cutting installation of a tool designed by OKB-2. The layout received negative feedback from representatives of the Ministry of Defense, however, the Ministry of Defense of the USSR became interested in the proposal to create an ACS of special power, and on December 16, 1967, by order No. 801 of the Ministry of Defense Industry, research work was started to determine the appearance and basic characteristics of the new ACS. The main requirement put forward for the new ACS was maximum range shooting - at least 25 km. The choice of the optimal caliber of the gun, at the direction of the GRAU, was carried out by the M. I. Kalinin Artillery Academy. In the course of the work, various existing and developed artillery systems were considered. The main ones were the 210 mm S-72 gun, the 180 mm S-23 gun and the 180 mm MU-1 coastal gun. According to the conclusion of the Leningrad Artillery Academy, the ballistic solution of the 210-mm S-72 gun was recognized as the most suitable. However, despite this, the Barrikady plant, in order to ensure the continuity of manufacturing technologies for the already developed B-4 and B-4M guns, proposed reducing the caliber from 210 to 203 mm. This proposal was approved by the GRAU.
Simultaneously with the choice of caliber, work was carried out on the choice of chassis and layout for the future self-propelled guns. One of the options was the chassis of the MT-T multi-purpose tractor, made on the basis of the T-64A tank. This option received the designation "Object 429A". A variant based on the T-10 heavy tank was also worked out, which received the designation "216.sp1". According to the results of the work, it turned out that an open installation of the gun would be optimal, while none of the existing types chassis, due to the high recoil resistance force of 135 tf when firing. Therefore, it was decided to develop a new undercarriage with the maximum possible unification of the nodes with the tanks in service with the USSR. The resulting studies formed the basis of the R&D under the name "Peony" (GRAU index - 2C7). "Pion" was supposed to enter service with the artillery battalions of the reserve of the Supreme High Command to replace the 203-mm B-4 and B-4M towed howitzers.

Officially, work on the new self-propelled guns of special power was approved on July 8, 1970 by the Decree of the Central Committee of the CPSU and the Council of Ministers of the USSR No. 427-161. He was appointed the lead developer of 2S7 Kirov Plant, the 2A44 gun was designed at OKB-3 of the Volgograd plant "Barricades". March 1, 1971 were issued, and by 1973 approved tactical and technical requirements for a new self-propelled guns. According to the assignment, the 2S7 self-propelled gun was supposed to provide a ricochet-free firing range from 8.5 to 35 km with a high-explosive fragmentation projectile weighing 110 kg, while it should have been possible to fire a 3VB2 nuclear round intended for the 203 mm B-4M howitzer. The speed on the highway had to be at least 50 km / h.
The new chassis with a stern gun mount received the designation "216.sp2". In the period from 1973 to 1974, two prototypes of the 2S7 self-propelled guns were manufactured and sent for testing. The first sample passed sea trials at the Strugi Krasnye training ground. The second sample was tested by firing, but could not fulfill the requirements for the firing range. The problem was solved by selecting the optimal composition of the powder charge and the type of shot. In 1975, the Pion system was adopted by the Soviet army. In 1977, at the All-Union Scientific Research Institute of Technical Physics, nuclear weapons were developed and put into service for the 2S7 self-propelled guns.

Mass production SAU 2S7 was launched in 1975 at the Leningrad plant named after Kirov. The 2A44 gun was produced by the Volgograd plant "Barricades". 2S7 production continued until the collapse of the Soviet Union. In 1990 in Soviet troops the last batch of 66 2S7M vehicles was transferred. In 1990, the cost of one 2S7 self-propelled artillery mount was 521,527 rubles. Over 16 years of production, more than 500 2C7 units of various modifications were produced.
In the 1980s, there was a need to modernize the ACS 2S7. Therefore, development work was started under the code "Malka" (GRAU index - 2S7M). First of all, the question was raised about replacing the power plant, since the B-46-1 engine did not have sufficient power and reliability. For the Malka, the V-84B engine was created, which differed from the one used in the T-72 tank by the features of the engine layout in the engine compartment. With the new engine, the self-propelled guns could be refueled not only with diesel fuel, but also with kerosene and gasoline.

The undercarriage of the car was also upgraded. In February 1985, self-propelled guns with a new power plant and upgraded undercarriage passed the test. As a result of the modernization, the ACS motocross resource was increased to 8,000-10,000 km. To receive and display information from the car of the senior officer of the battery, the gunner's and commander's seats were equipped digital indicators with automatic data reception, which made it possible to reduce the time for transferring the vehicle from traveling to combat position and vice versa. Thanks to the modified design of the stowage, the ammunition load was increased to 8 rounds. The new loading mechanism made it possible to load the gun at any angle of vertical pumping. Thus, the rate of fire was increased by 1.6 times (up to 2.5 rounds per minute), and the mode of fire - by 1.25 times. To monitor important subsystems, routine control equipment was installed in the car, which carried out continuous monitoring of weapon components, the engine, the hydraulic system and power units. Serial production of self-propelled guns 2S7M began in 1986. In addition, the crew of the car was reduced to 6 people.
In the late 1970s, on the basis of the 2A44 gun, a project was developed for a shipborne artillery mount under the code "Pion-M". The theoretical weight of the artillery mount without ammunition was 65-70 tons. The ammunition load was to be 75 rounds, and the rate of fire was up to 1.5 rounds per minute. The Pion-M artillery mount was supposed to be installed on Project 956 ships of the Sovremenny type. However, due to the fundamental disagreement of the leadership of the Navy with the use of a large caliber, they did not advance beyond the project of work on the Pion-M artillery mount.

The 2S7 Pion self-propelled gun was made according to a turretless scheme with an open installation of the gun in the aft part of the self-propelled guns. The crew consists of 7 (in the modernized version 6) people. On the march, all crew members are housed in the ACS hull. The body is divided into four sections. In the front part there is a control compartment with a place for a commander, a driver and a place for one of the crew members. Behind the control compartment is the engine compartment with the engine. Behind the engine-transmission compartment there is a calculation compartment, in which the stacks with shells are located, the gunner's place for the marching and places for 3 (in the modernized version 2) members of the calculation. In the aft compartment there is a folding coulter plate and a self-propelled gun. The hull 2S7 is made of two-layer bulletproof armor with a thickness of outer sheets of 13 mm, and internal sheets of 8 mm. The calculation, being inside the self-propelled guns, is protected from the consequences of the use of weapons of mass destruction. The case weakens the effect of penetrating radiation by a factor of three. The loading of the main gun during the operation of the self-propelled guns is carried out from the ground or from a truck using a special lifting mechanism installed on the platform, on the right side of the main gun. In this case, the loader is located to the left of the gun, controlling the process using the control panel.

The main armament is a 203-mm 2A44 cannon, which has a maximum rate of fire of 1.5 rounds per minute (up to 2.5 rounds per minute on the upgraded version). The gun barrel is a free tube connected to the breech. A piston valve is located in the breech. The barrel of the gun and recoil devices are placed in the cradle of the swinging part. The swinging part is fixed on the upper machine, which is mounted on the axis and fixed with basting. The recoil devices consist of a hydraulic recoil brake and two pneumatic knurlers located symmetrically with respect to the bore. Such a scheme of recoil devices makes it possible to reliably hold the recoil parts of the gun in the extreme position before firing a shot at any angles of vertical guidance of the gun. The recoil length when fired reaches 1400 mm. Lifting and turning mechanisms of the sector type provide gun guidance in the range of angles from 0 to +60 degrees. vertically and from -15 to +15 degrees. along the horizon. Guidance can be carried out both by hydraulic drives powered by pumping station SAU 2S7, and with the help of manual drives. The pneumatic balancing mechanism serves to compensate for the moment of imbalance of the swinging part of the tool. To facilitate the work of crew members, the self-propelled guns are equipped with a loading mechanism that ensures that shots are fed to the loading line and delivered to the gun chamber.
The hinged base plate, located in the stern of the hull, transfers the forces of the shot to the ground, providing greater stability to the self-propelled guns. On charge number 3, "Pion" could fire direct fire without installing an opener. The portable ammunition of the Pion self-propelled gun is 4 shots (for the modernized version 8), the main ammunition of 40 shots is transported in the transport vehicle attached to the self-propelled guns. The main ammunition includes 3OF43 high-explosive fragmentation shells, in addition, 3-O-14 cluster shells, concrete-piercing and nuclear ammunition can be used. Additionally, the 2S7 self-propelled guns are equipped with a 12.7 mm NSVT anti-aircraft machine gun and portable anti-aircraft guns. missile systems 9K32 "Strela-2".

To aim the gun, the gunner's position is equipped with a PG-1M panoramic artillery sight for firing from closed firing positions and an OP4M-99A direct-fire sight for firing at observed targets. To monitor the terrain, the control department is equipped with seven TNPO-160 prismatic periscope observation devices, two more TNPO-160 devices are installed in the hatch covers of the calculation department. For operation at night, some of the TNPO-160 devices can be replaced by TVNE-4B night vision devices.
External radio communication is supported by the R-123M radio station. The radio station operates in the VHF band and provides stable communication with stations of the same type at a distance of up to 28 km, depending on the height of the antenna of both radio stations. Negotiations between crew members are carried out through the intercom equipment 1V116.

The 2C7 used a V-shaped 12-cylinder four-stroke V-46-1 liquid-cooled supercharged diesel engine with an HP 780 power as a power plant. The V-46-1 diesel engine was created on the basis of the V-46 engine installed on the T-72 tanks. Distinctive features B-46-1 were small layout changes associated with its adaptation for installation in the engine compartment of the 2S7 self-propelled guns. Of the main differences was the changed location of the power take-off shaft. To facilitate starting the engine in winter conditions, a heating system was installed in the engine compartment, developed on the basis of a similar system of the T-10M heavy tank. In the course of modernization on self-propelled guns 2S7M power point was replaced by a V-84B multi-fuel diesel engine with an HP 840 power. The transmission is mechanical, with hydraulic control and a planetary rotation mechanism. It has seven forward and one reverse gears. The engine torque is transmitted through a bevel gear with a gear ratio of 0.682 to two onboard gearboxes.

Chassis 2S7 is made on the basis of the main tank T-80 and consists of seven pairs of dual rubber-coated support rollers and six pairs of single support rollers. In the rear of the machine are the guide wheels, in the front - the drive. In the combat position, the guide wheels are lowered to the ground to make the ACS more resistant to the loads during firing. Lowering and raising is carried out with the help of two hydraulic cylinders fixed along the axles of the wheels. Suspension 2C7 - individual torsion bar with hydraulic shock absorbers.
Photo 12. 
The preparation of the position for firing was carried out with the help of an opener in the aft part of the self-propelled guns. Raising and lowering the coulter was carried out using two hydraulic jacks. Additionally, the 2S7 self-propelled gun was equipped with a 9R4-6U2 diesel generator with an HP 24 power. The diesel generator was designed to ensure the operation of the main pump of the ACS hydraulic system during parking, when the vehicle's engine was turned off.
In 1969, in the Tula NIEMI, by decree of the Central Committee of the CPSU and the Council of Ministers of the USSR of May 27, 1969, work began on the creation of a new S-300V front-line anti-aircraft missile system. Studies conducted at the NIEMI together with the Leningrad VNII-100 showed that there was no chassis suitable for carrying capacity, internal dimensions and cross-country ability. Therefore, KB-3 of the Kirov Leningrad Plant was given the task of developing a new unified crawler chassis. The requirements for development were: full mass- no more than 48 tons, carrying capacity - 20 tons, ensuring the operation of equipment and crew in the conditions of the use of weapons of mass destruction, high maneuverability and maneuverability. The chassis was designed almost simultaneously with the 2S7 self-propelled gun and was unified with it as much as possible. The main differences include the rear location of the engine compartment and the drive wheels of the caterpillar mover. As a result of the work carried out, the following modifications of the universal chassis were created.
- "Object 830" - for self-propelled launcher 9A83;
- "Object 831" - for self-propelled launcher 9A82;
- "Object 832" - for the radar station 9S15;
- "Object 833" - in the basic version: for the multi-channel missile guidance station 9S32; performed by "833-01" - for the radar station 9S19;
- "Object 834" - for command post 9C457;
- "Object 835" - for launchers 9A84 and 9A85.
Production of prototypes of universal chassis Leningrad plant named after Kirov. Serial production was transferred to the Lipetsk Tractor Plant.
In 1997 by order Engineering Troops The Russian Federation developed a high-speed trench machine BTM-4M "Tundra" for making trenches and digging in frozen soil.
After the collapse of the Soviet Union in Russia, the financing of the armed forces was sharply reduced, and military equipment practically ceased to be purchased. Under these conditions, a conversion program was carried out at the Kirov Plant military equipment, within the framework of which, on the basis of the ACS 2S7, civil engineering machines were developed and began to be produced. In 1994, the highly mobile crane SGK-80 was developed, and four years later its modernized version appeared - SGK-80R. The cranes weighed 65 tons and had a lifting capacity of up to 80 tons. By order of the Department of Traffic Safety and Ecology of the Ministry of Railways of Russia, in 2004, self-propelled tracked vehicles SM-100 were developed, designed to eliminate the consequences of rolling stock derailments, as well as to carry out emergency rescue operations after natural and man-made disasters.

During the period of operation in the Soviet army, Pion self-propelled guns were never used in any armed conflict, however, they were intensively used in high-capacity artillery brigades of the GSVG. After the signing of the Treaty on Conventional Armed Forces in Europe, all Pion and Malka self-propelled guns were withdrawn from service. armed forces Russian Federation and relocated to the Eastern Military District. The only episode of the combat use of the 2S7 self-propelled guns was the war in South Ossetia, where the Georgian side of the conflict used a battery of six self-propelled guns 2S7. During the retreat, Georgian troops hid all six self-propelled guns 2S7 in the Gori region. One of 5 discovered Russian troops ACS 2S7 was captured as a trophy, the rest were destroyed.
In November 2014, in connection with the armed conflict, Ukraine began the reactivation and bringing into combat condition of its existing 2S7 installations.
In the 1970s, the Soviet Union attempted to re-equip the Soviet army with new models artillery weapons. The first example was the self-propelled howitzer 2S3, presented to the public in 1973, followed by: 2S1 in 1974, 2S4 in 1975, and in 1979 the 2S5 and 2S7 were introduced. Thanks to new technology Soviet Union significantly increased the survivability and maneuverability of their artillery troops. By the time the mass production of the 2S7 self-propelled guns began, the 203-mm self-propelled gun M110 was already in service with the United States. In 1975, the 2S7 was significantly superior to the M110 in terms of the main parameters: the firing range of the OFS (37.4 km vs. 16.8 km), the ammunition load (4 shots vs. 4), however, at the same time, the 2S7 self-propelled guns served 7 people against 5 on the M110. In 1977 and 1978, the US Army received improved M110A1 and M110A2 self-propelled guns, which were distinguished by a maximum firing range increased to 30 km, however, they could not surpass the 2S7 self-propelled guns in this parameter. An advantageous difference between the Pion and the M110 self-propelled guns is a fully armored chassis, while the M110 only has an armored engine compartment.
In North Korea, in 1978, on the basis of the Type 59 tank, a 170-mm self-propelled gun "Koksan" was created. The gun made it possible to fire at a distance of up to 60 km, but had a number of significant drawbacks: low barrel survivability, low rate of fire, low chassis mobility and the lack of portable ammunition. In 1985, an improved version was developed, this gun resembled the 2S7 self-propelled gun in appearance and layout.
Attempts to create systems similar to the M110 and 2C7 were made in Iraq. In the mid-1980s, the development of the 210 mm AL FAO self-propelled gun began. The gun was created as a response to the Iranian M107, and the gun had to be significantly superior to this self-propelled gun in all respects. As a result, a prototype ACS AL FAO was manufactured and demonstrated in May 1989. The self-propelled artillery mount was a G6 self-propelled howitzer chassis, on which a 210-mm gun was mounted. The self-propelled unit was capable of speeds up to 80 km/h on the march. The barrel length was 53 caliber. Shooting could be carried out both with conventional 109.4-kg high-explosive fragmentation shells with a bottom notch and a maximum firing range of 45 km, and shells with a bottom gas generator with a maximum firing range of up to 57.3 km. However, following in the early 1990s economic sanctions against Iraq prevented the further development of weapons, and the project did not go beyond the stage of prototypes.
In the mid-1990s, the Chinese company NORINCO based on the M110 developed a prototype 203-mm self-propelled gun with a new artillery unit. The reason for the development was the unsatisfactory firing range of the M110 self-propelled guns. The new artillery unit made it possible to increase the maximum firing range of high-explosive fragmentation shells to 40 km, and of active-reactive shells to 50 km. In addition, the self-propelled guns could fire guided, nuclear projectiles, as well as cluster anti-tank mines. Further, the production of a prototype development did not advance.
As a result of the completion of the Pion R&D, the Soviet Army received an SPG, which embodied the most advanced design ideas self-propelled guns high power. For its class, the 2S7 self-propelled guns had high performance characteristics (maneuverability and a relatively short time for transferring self-propelled guns to a combat position and back). Thanks to the caliber of 203.2 mm and the maximum firing range of high-explosive fragmentation shells, the Pion self-propelled gun had a high combat effectiveness: so, in 10 minutes of a fire raid, self-propelled guns are capable of "delivering" about 500 kg of explosive to the target. The modernization carried out in 1986 to the level of 2S7M allowed this self-propelled guns to meet the requirements for advanced artillery weapons systems for the period up to 2010. The only drawback noted by Western experts was the open installation of the gun, which did not allow the crew to be protected from shell fragments or enemy fire when working in position. Further improvement of the system was proposed to be carried out by creating guided projectiles of the "Smelchak" type, the firing range of which could be up to 120 km, as well as improving the working conditions of the ACS crew. In fact, after the withdrawal from the Armed Forces of the Russian Federation and redeployment to the Eastern Military District, most of the self-propelled guns 2S7 and 2S7M were sent for storage, and only a small part of them remained in operation.

But look at what an interesting sample of weapons:
Photo 16. 
Experimental self-propelled artillery mount. The development of the self-propelled guns was carried out by the Central Design Bureau of the Uraltransmash plant, the chief designer was Nikolai Tupitsyn. The first prototype of the self-propelled guns was built in 1976. In total, two copies of the self-propelled guns were built - with a gun from the Acacia self-propelled guns of 152-mm caliber and with a gun of the Hyacinth self-propelled guns. ACS "object 327" was developed as a competitor to the ACS "Msta-S", but turned out to be very revolutionary, it remained an experimental self-propelled gun. ACS was different a high degree automation - the reloading of the gun was carried out regularly by an automatic loader with an external location of the gun with the placement of the ammunition rack inside the body of the self-propelled guns. During tests with guns of two types, the self-propelled guns showed high efficiency, but preference was given to more "technological" samples - 2S19 "Msta-S". Testing and design of ACS were discontinued in 1987.
The name of the object "puck" was unofficial. The second copy of the self-propelled guns with the 2A37 gun from the self-propelled guns "Hyacinth" since 1988 stood at the training ground and was preserved in the Uraltransmash museum.
There is also such a version that the prototype of the self-propelled guns shown in the photo is the only mock-up image that was also worked out on the topics “object 316 ″ (prototype self-propelled guns “Msta-S“), “object 326″ and “object 327″. During the tests, guns with different ballistics were installed on a rotating platform tower. The presented sample with a gun from the self-propelled gun "Hyacinth" was tested in 1987.

Look at the self-propelled guns, but recently. Look at and how it looked before The original article is on the website InfoGlaz.rf Link to the article from which this copy is made -Self-propelled artillery mounts
Self-propelled unit ZIS-30
Light anti-tank self-propelled guns of open type. Created on an emergency basis at plant No. 92 (Gorky) using a rotating part of a 57-mm cannon and a semi-armored artillery tractor T-20 Komsomolets; it was mass-produced there from September 21 to October 15, 1941. 101 units were made.
Serial modification: in the aft part of the tractor body, a 57-mm gun is installed behind a standard shield. For greater stability when firing, the machine was equipped with folding coulters. On the roof of the cabin, a mounting bracket for the gun was mounted in a stowed position. The rest of the base machine remained unchanged.
Self-propelled guns ZIS-30 began to enter the troops at the end of September 1941. They were equipped with anti-tank batteries 20 tank brigades Western and Southwestern fronts. For all its shortcomings (poor stability, overloaded undercarriage, low power reserve, etc.), the ZIS-30, due to the presence of a powerful artillery system, quite successfully fought enemy tanks. However, by the summer of 1942, there were practically no such vehicles left in the troops.

Self-propelled gun SU-76
Light self-propelled guns for infantry escort, created on the basis of the T-70 tank with the use of the ZIS-Z divisional field gun. The most massive soviet self-propelled guns Second World War. Serial production was carried out by plants No. 38 (Kirov), No. 40 (Mytishchi) and GAZ. From December 1942 to June 1945, 14,292 units were manufactured.
Serial modifications:
SU-76 (SU-12) - a fixed armored cabin closed from above is installed above the aft part of the hull, which is elongated compared to the base tank. A ZIS-Z gun is mounted in the embrasure of the frontal cutting sheet. The power plant consisted of two engines connected to the power transmission in parallel. The units of the latter were also paralleled and connected at the level of the main gears. The driver was located in the bow of the car, and the gun crew of three people was in the wheelhouse. Combat weight 11.2 tons. Dimensions 5000x2740x2200 mm. 360 units made.
SU-76M (SU-15) - an armored cabin open at the top and partially behind. The power plant and transmission are borrowed from the T-70M tank. The layout and chassis remained unchanged. 13,932 units manufactured.
The first batch of self-propelled guns SU-76 (25 units) was manufactured by January 1, 1943 and sent to the training center self-propelled artillery. At the end of January, the first two self-propelled artillery regiments of a mixed organization - the 1433rd and 1434th were sent to the Volkhov Front to participate in breaking through the blockade of Leningrad. In March 1943, two more regiments were formed - the 1485th and 1487th, which participated in the battles on the Western Front.
In 1943, the light self-propelled artillery regiment had 21 self-propelled guns SU-76M. At the end of 1944 and at the beginning of 1945 for rifle divisions 70 self-propelled artillery battalions SU-76M were formed (16 self-propelled guns in each). In the first half of 1944, the formation of light self-propelled artillery brigades of the RVGK (60 SU-76M and 5 T-70) began.
By the end of the war, the Red Army had 119 light self-propelled artillery regiments and 7 light self-propelled artillery brigades.
Self-propelled guns SU-76M took part in the hostilities until the end of the Great Patriotic War, and then in the war with Japan. 130 self-propelled guns were handed over to the Polish Army.
In the post-war period, the SU-76M were in service Soviet army until the beginning of the 50s, and in the armies of a number of countries even longer. In the army of the DPRK, they took part in the war in Korea.

The first SU-122 self-propelled guns entered service with the 1433rd and 1434th self-propelled artillery regiments along with the SU-76. The baptism of fire took place on February 14, 1943, during a private operation of the 54th Army of the Volkhov Front in the Smerdyn region.
Since April 1943, the formation of self-propelled artillery regiments of a homogeneous composition began. They had 16 SU-122s, which until the beginning of 1944 continued to be used to escort infantry and tanks. However, such an application was not effective enough due to the low initial velocity of the projectile - 515 m / s and, consequently, the low flatness of its trajectory.

Self-propelled gun SU-85
The first Soviet full-fledged anti-tank self-propelled guns, designed to fight the new German heavy tanks. Created on the basis of the T-34 tank and self-propelled guns SU-122. Adopted by the Red Army by GKO Decree No. 3892 of August 7, 1943. During serial production from August 1943 to October 1944, 2644 units were manufactured at UZTM.
Serial modifications:
SU-85 (SU-85-11) - identical in design, layout and armor to SU-122. The main difference in armament is that instead of a 122-mm howitzer, an 85-mm cannon with the ballistics of an anti-aircraft gun 52K model 1939 was installed. The design and location of the commander's cupola were changed. 2329 units were made.
SU-85M-SU-85 with SU-100 hull. Manufactured 315 units.
The baptism of fire of the SU-85 took place in the fall of 1943 during the fighting in the Left-Bank Ukraine and for the liberation of Kyiv. Basically, SU-85s were used to escort T-34 tanks. In addition, self-propelled artillery regiments, which were part of some anti-tank brigades, were armed with them. The SU-85 was capable of fighting German Tiger and Panther tanks at a distance of 600 - 800 m.
SU-85 took part in the fighting until the end of the war.
In addition to the Red Army, vehicles of this type entered service with the Polish Army (70 units) and the Czechoslovak Corps (2 units). In Poland, SU-85s were operated until the end of the 50s, some of them were converted into ARVs.

Self-propelled gun SU-100 (object 138)
The most heavily armed medium anti-tank self-propelled guns of World War II. Developed on the basis of the T-34-85 tank and the SU-85 self-propelled guns. Adopted by GKO Decree No. 6131 of July 3, 1944. From September 1944 to the III quarter of 1945 UZTM produced 2495 units.
Serial modification:
in terms of design and layout, it is generally identical to the SU-85. A 100-mm cannon with the ballistics of a B-34 naval gun was installed. A new one was introduced commander's cupola, the thickness of the frontal armor has been increased, the ventilation of the fighting compartment has been improved, the suspension of the front road wheels has been strengthened.
SU-100s were used by the Red Army in the battles of the autumn-winter campaign of 1944 and at the final stage of the war in 1945. In terms of firepower, the SU-100 surpassed the best anti-tank self-propelled guns of the Wehrmacht "Jagdpanther" and was capable of hitting enemy heavy tanks at a distance of up to 2000 m.
Sufficiently large-scale SU-100 were used in repelling the German counteroffensive near about. Balaton (Hungary) in March 1945. In other sectors of the front, the use of the SU-100 was limited.
Production of the SU-100 in the USSR continued until 1947
(a total of 2693 units were produced). In the 50s, under a Soviet license, these self-propelled guns were produced in Czechoslovakia.
In the post-war period, the SU-100 was in service with the Soviet Army (until the end of the 70s), the armies of the countries participating in the Warsaw Pact, as well as many countries in Asia, Africa and Latin America. They were used in combat operations in the Middle East, in Angola, etc.

Self-propelled gun SU-152 (KV-14, object 236)
The first heavy self-propelled guns of the Red Army. Created on the basis heavy tank KV-1s using the oscillating part of a 152 mm hull howitzer-gun. Developed at plant number 100 (Chelyabinsk). Adopted by the GKO decree of February 14, 1943. Serial production was carried out at ChKZ. From February to December 1943, 671 units were manufactured.
Serial modification: the chassis and hull of the base tank remained unchanged. In front of the hull, a closed fixed box-shaped cabin is mounted, in the frontal sheet of which a tool is installed.
In July 1943, heavy self-propelled guns took part in the battles on the Kursk Bulge and became an unpleasant surprise for the Germans. The hit of an armor-piercing projectile weighing 48.8 kg with initial speed 600 m / s and even fragmentation weighing 43.5 kg with an initial speed of 655 m / s into the turret of the German Tiger tank tore it off the tank hull. As a result, these self-propelled guns, created as "pillbox fighters", were often used as anti-tank ones.
In 1943, the RVGK heavy self-propelled artillery regiment had 12 SU-152 units.

Developed to replace the SU-152 due to the withdrawal of the KV-1s tank from production. In general, it is similar in design and armament, but the base of the IS heavy tank is used. Serially produced at ChKZ and LKZ. From November 1943 to the III quarter of 1945, 4635 units were manufactured.
Serial modifications:
ISU-152 (object 241) - the chassis of the base tank has not changed much. An armored cabin is mounted in the front of the hull, in the front plate of which a ML-20S howitzer-gun is installed. Compared to the SU-152, the sight, swivel mechanism and some other details have been improved. Enhanced armor protection.
ISU-122 (object 242) - similar in design to ISU-152. Armed with a 122 mm A-19 hull gun mod. 1931/37 with piston lock. The cradle and recoil devices of the A-19 gun are the same as those of the ML-20 howitzer gun, which allowed the manufacturer to use the barrel of any of these calibers. Dimensions 9850x3070x2480 mm. Ammunition 30 shots.
ISU-122S (ISU-122-2, object 249) - 122 mm gun D-25S mod. 1943 wedge bolt. Dimensions 9950x3070x2480 mm.
ISU-152
The ISU self-propelled guns entered service with the heavy self-propelled artillery regiments of the RVGK (21 installations of 8 each) and were used to fight tanks and destroy enemy fortifications. Until the end of the war, 53 such regiments were formed. In March 1945, a heavy self-propelled artillery brigade (65 ISU-122) was formed.
Heavy self-propelled guns were used especially effectively during the assault on Koenigsberg and Berlin.
The Polish Army received 10 ISU-152 and 22 ISU-122 from the USSR.
After the Second World War, heavy self-propelled guns, mainly ISU-152, were repeatedly modernized and operated in the Soviet Army until the mid-60s. In addition to the USSR and Poland, they were in service with the Egyptian army and took part in the Arab-Israeli wars of 1967 and 1973.
In the post-war period, a significant number of tractors, ARVs and launchers of tactical and operational-tactical missiles were built on the basis of the decommissioned self-propelled guns.

The branch of pumped tank destroyers in the USSR will be subject to serious changes. In particular, a new TOP is introduced into the game: Object 268 4 variant. Consequently, the rest of the technique is shifted down, which leads to changes in some technical parameters. In addition, the weak and unplayable SU-101M1 will completely disappear from the branch. Let's see what awaits us.
Level 9: Object 263 performance characteristics, armament (a 122 mm M62-S2 gun is installed). 
Level 8: SU-122-54. The description of the vehicle and weapons are also changed here. In particular, the PT is losing a 100mm D54s gun. 
Level 7: SU-101. For the machine, it is also expected to change the performance characteristics and descriptions of equipment in the hangar. In addition, the PT loses two guns at once: a 122-mm D-25S model of 44 years, and a 122-mm M62-S2. Instead of them, more suitable weapons will be added.
Removed from the game, for vehicles below the seventh level, the change is not expected.
What is it for? The main goal of the developers is to optimize this branch of Soviet ATs for the current requirements of the game in order to make the gameplay more balanced and rich. Moreover, the introduction of a new tank into the game should arouse interest among tankers in this unpopular branch of development. Tanks with aft turrets require some skill to play, so many prefer to take the easier route.
The self-propelled anti-aircraft gun was created on the basis of the SU-76M self-propelled guns and was put into service in 1944. It had an open turret with circular rotation, was equipped with a rangefinder and a radio station. A total of 75 cars were produced.

The open-type self-propelled guns were created by installing the ZIS-2 anti-tank gun on the T-20 Komsomolets artillery tractor and put into service at the end of 1941. For greater stability when firing, the machine was equipped with folding coulters. On the roof of the cabin, a mounting bracket for the gun was mounted in a stowed position. A total of 101 cars were produced. TTX ACS: length - 3.5 m; width - 1.9 m; height - 2.2 m; weight - 4 tons; booking - 7-10 mm; engine type - 6 cylinder carburetor; power - 50 hp; specific power - 12 hp / t; speed on the highway - 60 km / h; power reserve - 250 km; main armament - 57-mm gun ZiS-2; additional - 7.62 mm DT machine gun; crew - 4 - 5 people.
