Heavy tank T-35

41
T-35 - a heavy tank of the 30s, produced in the USSR. It is the only five-tower in the world a tank serial production (in the period from 1933 to 1939 61 cars were produced). It was the most powerful tank of the Red Army of the 30s. Until 1941, he did not participate in battles, but was used during military parades, being a visible embodiment of the military power of the Soviet Union. T-35 participated in the battles of the initial stage of the Second World War, however, they were quickly lost, but, according to reports, mainly due to malfunctions.

Heavy tank T-35


Development and production

Work on a heavy tank in the USSR began at the end of the 20-ies, but the lack of the necessary experience in this area among domestic designers did not allow the development of a full-fledged combat vehicle. The way out of this situation was to invite German designers under the leadership of Edward Grotte, who arrived in the Soviet Union in 1930 and, together with young engineers, began to design a heavy tank. And although the TG tank created under the leadership of Grotte did not go into the series, the Soviet designers were able to gain invaluable experience, which was used in the design of domestic heavy combat vehicles.



After the work on the TG KB tank, which consisted of Soviet engineers working with Grote, was stopped under the guidance of N. Barykov, they began to develop their own heavy tank. The assignment was issued by the Office of Mechanization and Motorization of the Workers 'and Peasants' Red Army and it said: “By 01.08.1932, develop and build an 35-ton breakout tank of the TG type”. During the design of the T-35, the designers used the one and a half year experience of working on the TG tank, the test results of the German Grostruktor at Kazan and the materials of the commission for the purchase of armored vehicles in the UK.

The assembly of the first prototype, which received the designation T-35-1, ended 20 August 1932, and on September 1 the tank was shown to representatives of the UMM RKKA. The tank's weight was 42 tons, armor thickness — 30 — 40 millimeters; weapons included: one 76-millimeter and two 37-millimeter cannons (instead of 76-mm guns on the T-35-1 the layout was installed) and three machine guns. The crew of the tank consisted 10 — 11 man. Tank dimensions: length 9720 mm; width 3200 mm; height 3430 mm. Power reserve 150 km (on the highway). The 500-powerful M-17 engine allowed the tank to reach speeds of up to 28 kilometers per hour. The ground pressure was less than 0,7 kg / cm². Basic rollers grouped in pairs of three trucks on one side. The top of the main tower had a rounded shape.



The T-35-1 showed good results during the tests of the 1932 of the past year in the fall and met the military, however, there were several shortcomings in the power plant of the tank. In addition, the design of the pneumatic control and transmission actuators was too complicated and expensive for mass production. The designers proposed to refine the project on the identified deficiencies, to strengthen the armament and also to unify some details (for example, the main bashi) with the medium T-28 tank.

Tank production of the plant "Bolshevik" in February 1933 was allocated in a separate plant number 147 them. KE Voroshilov, while the Barykov Design Bureau was reformed into the OKMO (Experimental Engineering Machine Building Department), which began to refine the T-35-1.



The second sample, designated T-35-2, was assembled in April 1933, and on May 1 it was attracted to participate in a parade on Uritsky Square (former Palace) in Leningrad. The tank was different from the T-35-1, not only the main turret, but also the installation of another engine, the form of a bulwark and some other minor details.

In parallel, the design bureaus in the design bureau of the production tank T-35А. The T-35A tank had significant differences from the T-35-1 (2). The chassis was lengthened by one trolley, small machine-gun turrets had a different design, medium turrets having an enlarged shape were equipped with 45K 20-mm cannons, the hull shape was changed, besides, there were other minor differences. All this caused difficulties in manufacturing, since the T-35A tank was essentially a completely new machine.



Serial production of the T-35 tank was entrusted to the Kharkov Locomotive Plant to them. Comintern. Work on the improvement of the tank began in 1932, the head of the work was N. V. Tseyts. The 11.08.1933 T-35 was put into service, and with the 1934 the tank began to enter the troops.

In 1933, the 2 serial models were launched, and in 1934 they began small-scale production. In various years, the following number of tanks was launched: 1933 - 2; 1934 - 10; 1935 - 7; 1936 - 15; 1937 - 10; 1938 - 11; 1939 - 6.

In total, the 1933 prototype and the 1939 serial machine were released from 2 to 61 years.



During production, changes were made to the structure many times. For example, in 1937, the thickness of the side, upper and lower front plates was increased, the armor of the towers and the stern was made of 23-mm armor plates; engine power has been increased to 580 l. with.; tank weight increased to 52, and then to 55 tons. The number of crew members is from 9 to 11 people. The last six cars, released in 1938 — 1939, had conical towers, improved hull seals and a modified design of the side screens. Suspension elements were also strengthened.

Tank design

T-35 was a heavy tank of the classic layout, five-turreted, with a two-tier arrangement of guns and machine guns. Reserving a tank was adequate for the time it was created (it should be noted that it was not inferior to most tanks during the initial period of World War II), but it was not enough to accomplish the breakthrough task by the start of the war.



Chassis

The tank had a box-shaped body of complex configuration. The hull was welded (partially riveted) of armor plates of 10 thickness - 50 millimeters. The thickness of the armor of the T-35 tank was mainly millimeters 20 (bottom of the front, side and stern). The towers were made of armor thickness 25 — 30 millimeters. On the left, in the forward part of the hull, there was a driver's access hatch having a viewing slot covered with a glass block. During the march, the hatch could remain open (the opening was made upwards, a screw mechanism was used for fixation). To enter / exit the driver used a roof hatch located above his workplace. Initially, the hatch was made as a double wing, but was later replaced by a single folding one. A later modification of the tank, which has conical towers, had an oval hatch, made similar to the design of the BT-7 turret hatch. The main tower had a six-sided pedestal - the so-called “hexagon”. On its sides were located boxes designed to accommodate smoke curtain making devices. Behind the aft towers, air intake louvers were fitted, which were covered with armored screens, as well as the engine access hatch. The silencer was located behind the hatch. In the top sheet of the stern was made a round hole designed to install the fan. The hole was covered with a removable armored cap having blinds.



The main tower T-35 and the tower of the T-28 tank of the first releases were identical in design (until the introduction of the conical towers, the main tower did not have a full-time ball mount machine gun). It had a cylindrical shape and a developed feed niche. In the front of the axle mounted 76-millimeter gun, it was located to the right of the machine gun. For the convenience of the crew, the tower was equipped with a suspended floor.

The construction of medium-sized towers is identical to the towers of the BT-5 tank, but without a stern niche. The shape of the towers is cylindrical, with two hatches for crew access. The 45-mm cannon and the machine gun paired with it were mounted in its front part.



Small machine-gun turrets had the same design as the machine-gun turrets of the T-28 tank, however, unlike them, they were equipped with ring eyes used for dismantling. The cylindrical turrets in the bow had a projection shifted to the right. A DT machine gun in a ball mounting was placed in its front sheet.

The last production T-35 tanks had conical towers, while the design of their main tower was identical to the T-28 turret.



weaponry

Armament T-35 housed in two tiers of five towers. The 76,2-mm KT-28 27 / 32 model cannon was installed in the central turret (it was planned that PS-3 would be installed), which was a tank version of the regimental gun mod. 1927 d. Barrel length 16,5 caliber. The initial speed of the ammunition - 381 meters per second. As sighting devices used tank periscope arr. 1932 and telescopic sight arr. 1930 d. To the right of the gun was mounted a DT machine gun in a ball independent installation. In the tower niche a slot was made for the skid-mounted installation of the second DT machine gun. The slit was closed with a special armored flap. On some tanks, a standard ball mount was used to install the stern machine gun. Also, on the hatch of the tower with the help of the turret was installed another DT used for firing at air targets.

A pair of 45-mm guns 20K arr. 1932 was installed in small cannon turrets, which were located diagonally (right-front and left-rear). The initial velocity of the armor-piercing projectile was 760 m / s. The guns paired with DT machine guns were fixed on the axles in the movable armor. In machine-gun turrets, located diagonally (left-front and right-rear) were used to install DT machine guns.



The ammunition consisted of: 96 rounds for the 76-mm gun, 220 rounds for the 45-mm guns and 10 thousand rounds for machine guns.

Thus, the T-35 was armed with approximately one medium tank T-28 and two light tanks T-26.

Engine and transmission

V-shaped twelve-cylinder carburetor engine M-17 with liquid cooling, was installed in the rear of the case. Engine power at 1450 rpm was 500 l. with. This allowed the tank to reach speeds of up to 30 km / h on the highway and around 12 km / h on rough terrain. Fuel tanks with a capacity of 910 liters were provided with a power reserve of up to 150 km along the highway. The engine and manual five-speed gearbox were connected through the main clutch. The turning mechanism served as side clutches with band brakes.



Chassis

Each side of the caterpillar propulsion unit consisted of: eight rubber-coated small-diameter support rollers, six supporting rollers with rubber tires, guide wheels equipped with a screw tension mechanism, driving rear wheels with removable gear rims, open-wheel track chains with open hinges. The tracks were connected by fingers, which were locked with cotter pins. Tension rollers were installed between the front support rollers and the guide wheels, which prevent the front branches of the tracks from sagging during the overcoming of vertical obstacles.

Suspension - blocked, two rollers in the cart; suspension by means of two coil springs. The undercarriage was covered with 10-mm armored screens. The tank was able to climb up to 36 °, a ford 1,2 m deep, vertical walls 1,2 m high, ditches 3,5 m wide. The specific ground pressure was 0,78 kg / cm². The maneuverability of the tank was adversely affected by the large value of the ratio of its length to width (> 3).



Electric equipment

The tank was equipped with a radio station 71-TK-1, which has a hand-held antenna around the main tower, a telephone intercom for seven subscribers, a smoke suppression system. Electrical equipment was carried out on a single-wire circuit with a voltage network 12В.

Crew accommodation

During production, the number of crew members of the T-35 tank ranged from 9 to 11 people, depending on the design features of a particular series. In most cases, the crew accommodation looked like this. At the top - the main tower, which was unified with the T-28 tower, housed three crew members: a commander (also performing the functions of a gunner), a machine gunner, and a radio operator (also performing the functions of a loader). In the two towers in which 45-millimeter cannons were installed, there were two people each - a machine gunner and a gunner, in a machine-gun towers - one gunner. The main tower from the rest of the combat compartment was fenced off by a partition. The rear and front towers communicated in pairs. Between the tracks, in front of the tank, there was a department of management in which the driver was placed (had limited visibility due to the fact that the tracks of the tracks strongly came forward, often driving the machine almost blindly).



Equipment developed on the basis of the T-35 tank

Tank T-35 as a base was used to create an experimental heavy SAU (self-propelled artillery mount) SU-14. On the tank, instead of the towers, a spacious wheelhouse was installed offset to the stern. A 203- or 152-millimeter cannon was located in the wheelhouse. Both self-propelled built in a single copy. They were not accepted for service. In the winter of 1941, during the battle for Moscow, these vehicles, along with the T-100-U, were consolidated into a separate heavy company of SAU and sent to the front. Information about the combat use of the SU-14 was not found, but these machines have been preserved and are being exhibited today in Kubinka in the Museum of armored vehicles.



Combat use and service

The first T-35 tanks met the operational and technical requirements that were imposed on the heavy tanks of the Red Army. In addition, the fire power of the T-35 exceeded the power of any tanks in the world. Five machine guns (located in five rotating towers) and three guns provided a massive circular fire in all directions at the same time, which gave certain advantages in the fight against enemy infantry in the depths of his defense. However, this was the reason for the complexity of the design and required an increase in the number of crew members. Traction and dynamic qualities of the tank were insufficient, which especially affected when turning. The combination of these shortcomings did not allow to fully carry out the tasks that were assigned to a heavy tank. A large number of towers was the reason that the commander could not carry out effective fire control. Poor booking was the reason that the tank was vulnerable to artillery, and its low mobility and huge size made it an excellent target.



It was clear that a new concept of a heavy tank was needed. Experimental tanks QMS, and T-100 created in the framework of this new concept. The KV tank became the ancestor of the first successful Soviet series of heavy tanks.

Thus, the T-35 to the 1941 year was morally obsolete, but it was not removed from service. As of 22.05.1941, the Red Army had 48 T-35 tanks, which were in service with the sixty-seventh and sixty-eighth tank regiments of the thirty-fourth tank division of the Kiev Special Military District. Others were at the disposal of test sites and military schools. All T-35, which were at the disposal of the 34-th tank division, were located in the area of ​​Rava-Russkaya by the beginning of the war and were almost immediately lost. At the same time, all 7 machines were lost directly in the battles, 6 was under repair at the time of the outbreak of hostilities, and other 35s failed due to malfunctions, broke down during the march and were destroyed or abandoned by crews. The last use of two T-35 - in the battle of Moscow. Interestingly, there are great photos of abandoned T-35 tanks that were made by the Germans - simple soldiers and panzerwa tankers liked to be photographed around the “miracle of hostile technology”.



In the first weeks of the Second World War, the T-35 tank, fully operational and probably abandoned due to a fuel shortage, was sent by the Germans to the Kummersdorf test site, where it was carefully studied by German engineers. At the same time, they noted that there were difficulties with transporting the car - the tank did not fit into the railway envelope, and switching levers is an incredibly difficult and exhausting business. The further fate of this tank is unknown. The last case of the combat use of the T-35 tank was the use by the Germans at the end of April of the 1945 of one trophy T-35 during the defense of Berlin. This vehicle was transferred from the Zossen test site and incorporated into the fourth company of the eleventh tank regiment. As part of the company he participated in battles around the landfill, where he was soon shot down.

Tank T-35 as a symbol of the power of the Red Army

As already noted, until the beginning of the Second World War, the T-35 tank did not take part in the hostilities. T-35 periodically used in military maneuvers, but the main of the "battlefield" were the squares of Kiev and Moscow. T-35 became a truly visible embodiment of the power of the Red Army. Starting from the 33 year and up to the Second World War, the T-35 tanks took part in all parades. True, the number of tanks participating in the parade was small. For example, on November 7 40, the entire 20 machines were displayed at parades (10 in each city).



In addition, T-35 depicted on campaign posters. An interesting fact is that the image of the T-35 tank is present on the poster of 43. There was not a single T-35 in the troops at that time, but the “land battleship”, bristling with cannons, continued to carry out a propaganda function, personifying the might of the Red Army.

In addition, a simplified image of the T-35 tank was used in the design of the medal "For Courage".

    What can I say to all the tanks, it’s a pity that he only stayed along the roadsides in the 1941. Someone very poorly took into account the experience of the combat use of tanks in Spain and the operating experience.

              I will not argue, it seems that "one field is a berry", but only the T-35 was mass-produced, therefore it was brought to mind. It was in service until the Second World War, 48 tanks were part of the 34td KoVO (the area of ​​deployment of Rava-Russkaya. They were going to use them and, in comparison with a considerable part of the German tanks that were part of the 1st TGr Kleist, they did not look wretched, out of 822 tanks, 265 were T -I and T-II, and 66 more were commanders.

    Kars,

    I, of course, am not an expert on BT, but I will express my bewilderment.
    For the 30s, probably "a tank for all tanks." But how he could effectively fight in the Great Patriotic War I can't imagine. The speed and maneuverability are low, the range is small, the silhouette is huge. In terms of size and armament, it is a land dreadnought, and the booking leaves much to be desired.
    Breakthrough tank? No.
    Infantry support on the battlefield? Yes. Until then, until three and a half meters catch a few shells. Yes, and patency probably was not up to par.

          On 25 of April 1940 of the year, Gruppe Pellangahr (created from units of the 196 Infantry Division and Special Forces PzAbt zbV 40) moved to the English fortified positions near the village of Kvarn, held by the 1th Battalion of the Royal Yorkshire Infantry. The British did not have heavy weapons except two 3-inch mortars and five 25mm. French anti-tank guns Hotchkiss. In the German vanguard 3 tanks were moving. At least one of them was NbFz VI. The British did not open fire until the German tanks came at a distance of 150 meters. Having opened fire from such a short distance, the British did not allow the German tanks to maneuver. It was at this moment that the shell of one of the anti-tank guns immobilized NbFz VI. The Germans stopped the attack and called in aircraft. The British held out until the evening of April 26, then retreated. The remains of NbFz VI (part of the differential) can still be seen today in a small museum in the village of Kvarn. And until the end of the 1980's at the place where the English left him in April 1940, one could see the well-preserved 25mm. anti-tank gun.


          In principle, I still have not given up hope to collect the T-28 and T-35, although the quality of the models is not for me.

    The idea of ​​creating a sort of land all-destroying battleship excited the military in all militarily developed countries. And the scope of industrialization, the craving for gigantomania and the general enthusiasm in the young USSR led to the birth of the five-tower land "dreadnought" T-35. At a time when cavalry was the dominant force on the battlefield, and anti-tank artillery was essentially absent, an attractive perspective would seem to be waiting for such a tank.


    Work on the creation of heavy tanks began in the USSR in December 1930, when the Office of Motorization and Mechanization (UMM) of the Red Army signed an agreement with the Chief Design Bureau of the Gun-Weapon and Machine Gun Association to develop a project for a heavy breakthrough tank, designated T-30. It was supposed that it would be a 50-ton machine, armed with two 76-mm guns and five machine guns. But the lack of domestic experience in tank building did not even allow the creation of a full-fledged combat vehicle project of this class. In early 1932, after sketching and building a wooden model of the tank, all work on the T-30 was discontinued, due to its complete failure, as a combat vehicle.

    The attempt by the Autotank-Diesel Department of the OGPU Economic Administration (ATDU ECU OGPU) (the prison design department where the arrested designers worked) was not successful until 1931 to develop a project for a breakthrough tank weighing 75 tons. Like the T-30, this project had many shortcomings that precluded the possibility serial construction of such a machine.

    Only the intervention of foreign specialists moved the matter off the ground. In March 1930, a group of engineers headed by Edward Grotte arrived in the Soviet Union from Germany. At the Leningrad plant "Bolshevik" they formed the design bureau AVO-5, which included this group. In addition to German engineers, the group also included young Soviet engineers. After the TG-1931 tank was built in August 1 and tested, Grotte and German engineers refused further services for a number of reasons. AVO-5 was reorganized, and it was headed by a young and energetic engineer N.V. Barykov, who previously worked as Grotte's deputy.

    The new design bureau received from the UMM RKKA the task "By August 1, 1932, to develop and build a new 35-ton TG-type breakthrough tank." This machine was assigned the T-35 index. The work on the tank was personally monitored by M. Tukhachevsky, who initiated the creation of tank corps. When designing the T-35, one and a half years of experience on the TG-1 were taken into account, as well as the results of tests of German tanks "Grosstraktor" at the proving ground near Kazan and materials (intelligence) of the commission for the purchase of armored vehicles in Great Britain.

    Two prototypes T-35-1 and T-35-2 were successively created, differing from each other by engines (M-6 and M-17, respectively), transmission, gearbox design and bulwark shape. Also, at the personal direction of I.V. Stalin made the unification of the main towers of the developed heavy T-35 and medium T-28 (three-tower). Both prototypes participated in the military parade on May 1, the T-35-1 in Moscow, and the T-35-2 in Leningrad.
    In parallel with the assembly of the T-35-2 in Leningrad, the development of drawings of the serial T-35A tank was underway. Moreover, the T-35-2 was considered only as a transitional model, identical to the serial model only in the transmission part. In accordance with the Decree of the Government of the USSR in May 1933, serial production of the T-35 was transferred to the Comintern Kharkov Locomotive Plant (KhPZ). There, in early June 1933, the T-35-2 machine and all the working documentation for the T-35A, which had not yet been tested, were urgently sent.

    The design of the latter was significantly different from both prototypes. The tank had a chassis extended by one bogie, new small machine gun turrets, oversized medium turrets with 45 mm 20K guns, a modified hull shape, etc. In essence, this was already a new machine, which caused a number of difficulties in its manufacture. Several factories were connected to the production of the T-35, including Izhora (armored corps), Krasny Oktyabr (gearboxes), Rybinsk (engines). The T-35 was manufactured according to the nodal principle (9 nodes), while the final assembly of the first machine was carried out on special goats (slipways). It began on October 18, 1933 and ended by November 1. After preliminary running-in, the tank took part in a festive parade in Kharkov (at that time the capital of Ukraine) on November 7. On the same day, both prototypes, the T-35-1 and T-35-2, were shown at the parade in Moscow. Serial production began in 1934. The repression of the engineering and technical workers that began did not contribute to the rapid development of the production of the T-35. For example, in March 1934, the KhPZ received an instruction "about the need for a thorough check of design calculations, especially for the gearbox, since the designer Andrykhevych, now arrested, took part in its design."

    The T-35 was grandiose for its time not only in size, but also in financial costs for its development, construction and operation (the T-35A cost the treasury 525 thousand rubles; for the same money it was possible to build nine light tanks BT-5 )

    The design of the T-35.

    The heavy five-turret T-35 tank was created to qualitatively strengthen the combined arms forces during the breakthrough of the enemy’s particularly strong and well-fortified defensive lines and entered the reserve of the High Command. The T-35 had a classic layout layout. The control compartment was located in front, the combat - in the middle, and the motor-transmission - in the stern. This provided a good overview of the terrain, and significantly reduced the space to be shot in the forward direction.

    It was a five-tower combat vehicle with a two-tier arrangement of weapons. A 76,2-mm cannon and machine gun were installed in the central upper tower, there were also three crew members: a commander (aka gunner), a machine gunner and a radio operator, who was also loading. The central tower was equipped with a hanging shelf, which housed part of the ammunition, which greatly improved the working conditions of the crew, and had a circular rotation in the horizontal plane. For the rest, the firing sectors are limited by angles of 165 ° -235 °. Two diagonally located towers housed a 45-mm cannon and machine gun, and two crew members - a gunner and a machine gunner. In machine-gun towers, one machine gunner was also located. The central tower was separated from the rest of the fighting compartment by a partition. The front and rear towers were paired with each other, the control compartment was in the front and connected to the battle via the side hatch in the partition. Separate units of the vehicle are unified with units of the T-28 tank.

    The T-35 was produced in several small series, while its design was repeatedly amended. In 1937, increased the thickness of the armor of the upper and lower frontal and side sheets. feed and towers from 20 to 25 mm., the checkpoint, side clutches, oil tank, electrical equipment were modernized, the bulwark design was changed, special seals were designed and installed on the machines to protect the machine from getting into water. In addition, the silencer was removed inside the case, and only the exhaust pipes closed by armored covers were brought out. Thanks to this modernization, the reliability of the tank has greatly increased. The maximum engine power was increased to 580 hp. The mass of the tank increased to 52, and then to 55 tons. The number of crew members on vehicles of different series ranged from 9 to 11 people. The last batch of 6 cars produced in 1939 had conical towers, a redesigned side screens, and improved hull seals. As of January 1, 1941, there were 56 T-35 tanks of various modifications in the Red Army. A total of 1933 tanks were manufactured from 1939 to 61.

    Reservations.

    Reservation of the tank provided protection for the crew and internal equipment at all distances from the fire of heavy machine guns and fragments of shells, mines and bombs. Armored rolled sheets with a thickness of 15-35mm. connected by electric welding and partially rivets. In the front of the case, they were tilted at relatively large angles to a vertical plane, which increased their protective properties.

    Armament.

    The artillery armament consisted of a 76 mm short-barreled gun mounted in the mask of the central turret (unified with the T-28) and two 45 mm tank guns located in the front right and rear left towers (similar to BT-5 towers). Machine-gun armament was represented by two 7,62-mm tank DT machine guns paired with 45-mm guns, and three more were located in the ball bearings of the central and machine-gun turrets (similar to BT-2 towers). The cannon and machine gun mounted in the central tower comprised the upper tier of armament, while the guns and machine guns of the towers located around the central one were the lower one.
    The 76,2 mm KT-28 gun had a 16,5-caliber barrel, could fire with armor-piercing and high-explosive fragmentation shells (weight 6,5 kg, initial velocity 381 and 530 m / s, respectively). Its rate of fire was 3-4 rounds per minute. The effect of the shells was quite effective. So, when a fuse of a high-explosive fragmentation projectile was mounted on a fragmentation effect, at break it created an area of ​​actual destruction along the front 30 and to a depth of 5 m; when the fuse was set to high explosive, a funnel with a diameter of 1,5 and a depth of 0,5 m formed in medium-density soil.

    45-mm guns had barrel lengths of 46 calibers. They could fire armor-piercing and fragmentation shells (mass of 1,42 and 2,13 kg, initial velocity of 760 and 335 m / s, respectively). The rate of guns was 8-12 rounds / min. Armor-piercing shells at a firing range of 500 m and at a meeting angle with a 90 ° obstacle penetrated armor up to 43 mm thick.

    The ammunition load consisted of 96 rounds for the 76,2-mm cannon, 220 rounds for the 45-mm cannons and 10000 rounds for machine guns (158 magazines). Observation in a combat situation was carried out through viewing slots with glass blocks, periscopes, periscopic and telescopic sights. It should be noted that in terms of the caliber of the gun installed in the central tower and the total number of guns, the T-35 was superior to the same type 5-turret British Independent, MkI and MkII Vickers tanks, which had a 47-mm tank gun and a German 3-turret PzKpfwV "Rheinmetall", armed with 75-mm and 37-mm twin tank guns.

    The composition and placement of T-35 weapons are optimal for a multi-tower tank. Five towers located in two tiers made it possible to concentrate massive fire from 76-mm, one 45-mm guns and three machine guns forward backward or on any side. However, such great firepower required an increase in the number of crew members and the complexity of the tank design.
    Equipment.

    The electrical equipment was made according to a single-wire circuit with a voltage of 12 V. The ignition system was powered by two magnetos, each of which served six candles in two rows of cylinders. System wires are shielded. The reliability of its work was ensured by the installation of two candles on each cylinder. The machine was equipped with manual fire extinguishers and a chimney device DPT-3.

    External communication was carried out by a tank receiving-transmitting telephone and telegraph simplex radio station 71-TK-1 with a handrail antenna mounted on the central tower. It provided communications at a distance of 15 km on the go and up to 30 km in the parking lot. On tanks of the latest releases, it was replaced by a 71-TK-3 radio with a whip antenna, which was less vulnerable in battle. For internal communications there was a tank intercom TPU-7 for seven subscribers.

    Engine and transmission.

    The machine was equipped with a 12-cylinder V-shaped carburetor aircraft engine of liquid cooling M-17T with a capacity of 500 hp, which allowed to reach speeds of up to 30 km / h. It was located longitudinally in the engine-transmission compartment, with the tip of the crankshaft toward the aft. The engine had relatively small overall dimensions (500 kg at 1634x866x1172 mm). Aviation gasoline was used for its work. The engine was started using an electric starter. The mechanical transmission consisted of a multi-disc main dry friction clutch, a four-speed gearbox, side clutches with floating belt brakes (turning mechanisms), and two-stage final drives. Some of its units and components were subsequently used in the manufacture of an open heavy self-propelled gun SU-14-1, armed with a 203-mm howitzer B-4 of the 1931 model.

    The caterpillar mover (for one side) consisted of
    small-chain track chain of the pin chain with an open joint, eight double track rollers included in four bogies, six double track rollers, a guide wheel with a track tension mechanism and a rear-wheel drive with removable ring gears. A tension roller was installed between the guide wheel and the front track roller, which prevents the front branch of the track chain from deflecting when overcoming profile obstacles. Track rollers had an external cushioning in the form of rubber bandages.

    The suspension of the tank is blocked by two rollers. The suspension of each trolley was carried out by two coil springs. The chassis was covered with 10-mm armor screens. The patency of the tank was not bad for its type, and the maneuverability was insufficient. The machine could not turn in place due to the fact that the ratio between the length of the supporting surface of the tracks and track was violated (2,52, instead of permissible 2). The specific pressure was 0,78 kgf / cm2. When driving on the highway, one gas station was enough for 150 km.

    For Kibb, and in the background the T-28, it’s not clear what kind of modification.
    The main modifications of the T-35 tank.

    In the mid and late 30s, on the basis of the T-35 (using a number of units of the T-28 tank), a self-propelled artillery installation with a 203-mm howitzer B-4 (SU-14) and a 152 mm gun B -10 (SU-14A). After changes and improvements, the SU-14 became known as the SU-14-1 and in 1936 it was tested by firing and mileage at the training ground. At the end of 1939, one of the SU-14 vehicles with the 152-mm Br-2 gun (SU-14Br-2) was additionally booked and sent to the Karelian Isthmus for firing at Finnish pillboxes.

    Analysis of the design and concept of the T-35 tank.

    The T-35 was an unenviable fate. It was at that moment when he began to enter the arsenal of the Red Army, on the battlefields in Spain his brothers passed a stern exam. Anti-tank artillery appeared on the battlefield, at once ending with bulletproof armor, and, as a result of this, with the very concept of multi-tower tanks. It was obvious that it was impossible to defend multi-tower land dreadnoughts with any serious armor protection. The required weight and mass characteristics of the tank and, accordingly, the required engine power, capable of providing acceptable mobility on the battlefield (the requirements for which also increased sharply), caused only hysterical laughter among the designers of the late 30s. T-35, as an expression of the idea of ​​a multi-tower tank, died immediately after its birth. In fairness, we note that all other representatives of the tank family of the early 30s also died suddenly.

    The inconsistency of the idea of ​​dispersal of fire, which was addressed in connection with unsuccessful attempts to create a viable central aiming system (similar to dreadnoughts), also became visible. The tank commander could not give timely directions to all the towers. Single shooters in the towers with insufficient means of observation did not have the opportunity to choose the main target. Since targeted fire was carried out from short stops, the driver is not able to fulfill the requirements of all gunners, except to completely stop the tank. But then the tank itself turned into a motionless target.

    The appearance of attack aircraft and dive bombers capable of “planting” a bomb precisely at a target, alas - sedentary, made multi-towered heavy mastodons no more than “whipping boys” on the battlefield, which had changed so much over some five years.

    In most modern publications, this is why the T-35 tanks, as the most colorful representative of the multi-turret concept, are given a humiliating and destructive assessment of their combat capabilities.
    But, for the sake of truth, I would like to say good words to him and to those people who conceived, designed, built and fought on it.

    What was the use of tanks supposed to look like in the early 30s? Like that:

    A) T-28 medium tanks break through the enemy’s defenses.
    B) the heavy T-35s provide their combat stability, suppressing, due to its more powerful weapons, its defense units and neutralizing possible tank counterattacks.
    C) T-26 infantry escort tanks help this infantry completely crush resistance and develop success by suppressing individual firing points.
    D) wheeled and tracked tanks BT-2, BT-5 and BT-7 develop initial success and break free into the operational space.
    D) machine-gun tanks T-37, T-38, and T-27 tankettes as part of horse-mechanized units break into the depths of defense and act against operational reserves and the environment.

    So, the T-35 was entrusted with the task of breaking through the front line of the enemy’s defense, “breaking” its defense, suppressing firing points, destroying the enemy’s manpower, i.e. the crushing of the insurmountable duet for the infantry “machine gun + barbed wire”. According to the designers, three guns and five machine guns were supposed to provide the possibility of conducting massive and highly maneuverable circular fire simultaneously in all directions, which is very important in the fight against infantry in the depths of the enemy’s defense. That is why the tank had so many machine guns, guaranteed to "clear" the space around the tank (and therefore - before the advancing infantry) from enemy shooters who were seated in the trenches. The main caliber - 76mm., Was intended to suppress the fortifications of the field or village type. And completed the picture two 45mm guns that provide anti-tank defense.

    The infantry, which at that time did not have effective anti-tank weapons (there were no anti-tank artillery yet!), Had no chance of encountering this armada.

    Consider the main disadvantages of the T-35 tank, but - in relation to the conditions of warfare for which this tank was created.

    Low speed - up to 30km / h. For a machine whose operational-tactical purpose is to “crack” the defense and clear the path for infantry, it should be recognized as sufficient. For operations on the operational expanse in the T-34 style - yes, it’s not enough, but in order to get ahead of the infantry, “roll” the enemy machine gunners in the trenches in their own trenches - completely. And others should have developed success - BT-shki.

    Low maneuverability. For a tank not intended for oncoming maneuvering tank battles with its own kind, and it was difficult to even imagine such a form of battle in the early 30s, it was simply not required. And to hide behind the folds of the terrain or to go around anti-tank defense nodes was not required, again, in the absence of such, as such.
    Bulletproof armor. The armor protection corresponded to the level generally accepted at that time. There were no mention of any anti-tank rifles, faustpatrons or bazookas.

    Weak main caliber (76mm short-barreled.). It was enough to break through the front line, suppress machine-gun nests and destroy the infantry. For more serious fortifications, the concept of an artillery-air strike was developed, with 122-mm and 152-mm guns and TB-3 and SB-2 bombers.

    Aircraft engine. Just remember about American tanks with the same engines. And - with star-shaped, but not in-line! Yes - 10 years later.

    Great crew. Yes, 11 people (9 on the last vehicles) are the infantry squad. But! In the FIVE turret tank. Quite single-tower KV-1 had a crew of 5 people.

    Unreliable transmission. Yes, there is, the fact is there. Admittedly, the KV and even the T-34 had an unreliable transmission. Therefore, this drawback is more likely than accidental. The absence in the USSR of highly qualified specialists and engineers made itself felt.

    Therefore, it is safe to say that for the conditions of hostilities of the early 30s, the T-35 tank was a very successful project. And, once again, only the appearance of anti-tank artillery and the associated change in battle tactics determined the instant obsolescence of the T-35. Although he managed to fight in the 41st. His peers by that time had long since become scrap metal. The loss of fifty tanks in the first two weeks of the war fades before the stunning losses of the Red Army in all types of equipment and weapons at that time. It was not a matter of technology, but of the inability to correctly command troops.

      It could very well be. In principle, I already wrote that modern MBT needs a powerful, independent anti-aircraft defense (not just air defense, but the top) firing point. That would be a minimum of two fire channels. And with the development of remote control, it can be fit into small dimensions and placed in the stern of the tower.

    The history of the use and service of the T-35 tank.

    The lessons of the Spanish Civil War have been taken into account. On June 27, 1940, a meeting "On the Red Army Armored Weapons System" was held in Moscow, at which the issue of promising types of tanks and the removal of old models from service was considered. With regard to the T-35, opinions were divided, but in connection with the reorganization of the Red Army tank forces and the formation of mechanized corps, the T-35 decided to “remain in service until complete wear and tear, having studied the issue of enhancing their reservation (by the method of mounted armored screens) to 50 - 70 mm

    As a result, almost all of the vehicles ended up in the 67th and 68th tank regiments of the 34th Panzer Division of the 8th Mechanized Corps of the Kiev Special Military District. Several cars were in various military schools. The combat career of the T-35 was very short.

        Why, from CT it is impossible to break through the concrete bunker, even built in haste. You can get into the embrasure, but you need to approach 150-200 meters, and here the armor and dimensions of the machine will not allow, but from ZiS 5 you can shoot from 700 meters and get there if the gunner is normal and the sight is not yellow-green. And here the KV armor will work, because it’s unrealistic to pierce it from 700 meters in 41-42 with an instrument that they could put in the bunker - the FlACs did not put in the bunkers

          They didn’t fall into the embrasure directly from the 45, and they didn’t put armor-piercing guns in the 1934-40 either. (We won’t touch the maginot)
          Yes, and not in the pillboxes, but in the Tiger. With its 35 mm, the T-45 could have wrestled with its modern tanks until the 40 of the year. From 1933 by 1939 - 6 of years, 40-43 -3 of the year in KV.

              So from a cannon it is possible, but the KT that stood in the "big tower" of the T35 at that time is no longer a cannon, even, it is rather a howitzer, so why do you need to make a five-turret tank if you can make a dozen conventional ones instead, for example T50 with the same 45mm cannons , which by the way are the same PAK, only with bored barrels
