No one at the Krupp plant in 1936 could have imagined that this massive vehicle, equipped with a short-barreled infantry support gun and considered auxiliary, would be so widely used. With a final total of 9,000 units, it became the most mass-produced tank ever produced in Germany , the production volumes of which, despite the shortage of materials, grew to the very last days World War II in Europe.

Wehrmacht workhorse

Despite the fact that they appeared combat vehicles, more modern than the German T-4 tank - “Tiger”, “Panther” and “Royal Tiger”, it not only accounted for most weapons of the Wehrmacht, but was also part of many elite SS divisions. The recipe for success was probably the large hull and turret, ease of maintenance, reliability and robust chassis, which allowed for an expanded array of weapons compared to the Panzer III. From the Model A to the F1, early versions using a short 75 mm barrel were gradually replaced by the "long" ones, F2 to H, with a very effective high-velocity gun inherited from the Pak 40, which could cope with the Soviet KV-1 and T -34. In the end, the T-4 (photo presented in the article) completely surpassed the Panzer III both in numbers and in its capabilities.

Krupp prototype design

It was originally assumed that the German T-4 tank, specifications which were determined in 1934 by the Waffenamt, will serve as an “accompanying vehicle"to hide his true role, prohibited by the terms of the Treaty of Versailles.

Heinz Guderian took part in the development of the concept. This new model was supposed to become an infantry support tank and be placed in the rearguard. It was planned that at the battalion level there should be one such vehicle for every three Panzer IIIs. Unlike the T-3, which is equipped with a variant of the standard 37 mm Pak 36 gun with good anti-tank characteristics, the short barrel of the Panzer IV howitzer could be used against all types of fortifications, blockhouses, pillboxes, anti-tank guns and artillery positions.

Initially, the weight limit for a combat vehicle was 24 tons. MAN, Krupp and Rheinmetall-Borsig created three prototypes, and Krupp received the main contract. The suspension was initially completely new, with six alternating wheels. Later the Army required the installation of rod springs, which provided better vertical deflection. Compared to the previous system, this made the ride smoother, but the need for a new tank stopped further development. Krupp returned to a more traditional system with four twin-wheel bogies and leaf springs for easier servicing. A crew of five was planned - three were in the turret (commander, loader and gunner), and the driver and radio operator were in the hull. Combat compartment was relatively spacious, with improved sound insulation in the rear engine compartment. The inside of the German T-4 tank (photos in the material illustrate this) was equipped with an onboard communication system and radio.

Although not very noticeable, the Panzer IV's hull is asymmetrical, with the turret offset 6.5 cm to the left and the engine 15 cm to the right. This was done in order to directly connect the turret ring to the transmission for faster rotation. As a result, the ammunition boxes were located on the right.

The prototype, developed and built in 1936 at the Krupp AG plant in Magdeburg, was designated Versuchskraftfahrzeug 622 by the Army Weapons Office. However, in the new pre-war nomenclature it quickly became known as the Pz.Kpfw.IV (Sd.Kfz. 161).

The tank had a Maybach HL108TR gasoline engine with a power of 250 hp. s., and a SGR 75 gearbox with five forward and one reverse gears. The maximum speed tested on a flat surface was 31 km/h.

75 mm gun - low-velocity Kampfwagenkanone (KwK) 37 L/24. This weapon was intended for firing at concrete fortifications. However, some anti-tank capability was provided by the Panzergranate armor-piercing projectile, whose speed reached 440 m/s. It could penetrate a 43 mm sheet of steel at a distance of 700 m. Two MG-34 machine guns completed the armament, one coaxial and the other at the front of the vehicle.

In the first batch of Type A tanks, the thickness of the hull armor did not exceed 15 mm and the turret armor did not exceed 20 mm. Although it was hardened steel, such protection could only withstand light firearms, light artillery and grenade launcher fragments.

Early "short" preliminary episodes

The German T-4 A tank was a kind of preliminary series of 35 units produced in 1936. The next was the Ausf. B with a modified commander's canopy, a new Maybach HL 120TR engine developing 300 hp. pp., as well as a new transmission SSG75.

Despite the extra weight, maximum speed increased to 39 km/h, and protection was strengthened. The thickness of the armor reached 30 mm in the front inclined part of the hull and 15 mm in other places. In addition, the machine gun was protected by a new hatch.

After the production of 42 vehicles, production switched to the German T-4 C tank. The thickness of the armor on the turret increased to 30 mm. Total weight amounted to 18.15 tons. After delivery of 40 units in 1938, the tank was improved by installing a new Maybach HL 120TRM engine for the next hundred vehicles. It is quite logical that modification D followed. The Dora can be distinguished by the machine gun newly installed on the hull and the embrasure placed outside. The thickness of the side armor increased to 20 mm. A total of 243 vehicles of this model were manufactured, the last of which was at the beginning of 1940. Modification D was the last pre-production one, after which the command decided to increase the scale of production.

Standardization

The German T-4 E tank was the first large-scale series to be produced during the war. Although many studies and reports point to the lack of penetration of the Panzer III's 37mm gun, replacing it was not possible. Looking for a solution to conduct testing on one prototype Panzer IV Ausf. D, a modification of the Pak 38 medium-velocity 50 mm cannon was installed. The initial order for 80 units was canceled after the end of the French campaign. In tank battles, in particular against the British Matilda and the French B1 bis, it finally became clear that the thickness of the armor was insufficient and the penetrating power of the gun was weak. In Ausf. E retained the short-barreled KwK 37L/24 gun, but the thickness of the front armor was increased to 50 mm, with 30 mm steel plate overlays as a temporary measure. By April 1941, when this modification was replaced by Ausf. F, its production reached 280 units.

The last "short" model

Another modification significantly changed the German T-4 tank. The characteristics of the early F model, renamed F1 when the next one was introduced, changed due to the replacement of the front cover plate with a 50 mm plate and an increase in the thickness of the side parts of the hull and turret to 30 mm. The total weight of the tank increased to over 22 tons, which forced other changes such as increasing the width of the tracks from 380 to 400 mm to reduce ground pressure, with a corresponding change in the two idler and drive wheels. The F1 was produced in 464 units before its replacement in March 1942.

The first "long"

Even with the armor-piercing Panzergranate round, the Panzer IV's low-velocity gun was no match for heavily armored tanks. In the context of the upcoming campaign in the USSR, a decision had to be made on a major upgrade of the T-3 tank. The now available Pak 38L/60 gun, the effectiveness of which has been confirmed, was intended for installation in the Panzer IV turret. In November 1941, the prototype was completed and production was scheduled. But during the first battles with the Soviet KV-1 and T-34, production of the 50 mm gun, also used in the Panzer III, was discontinued in favor of a new, more powerful model from Rheinmetall based on the 75 mm Pak 40L/46 gun. This led to the development of the KwK 40L/43, a relatively long caliber equipped to reduce recoil. The initial velocity of the Panzergranade 39 projectile exceeded 990 m/s. It could penetrate 77 mm armor at a distance of up to 1850 m. After the creation of the first prototype in February 1942, mass production of the F2 began. By July, 175 units had been manufactured. In June, the German T-4 F2 tank was renamed T-4 G, but for the Waffenamt both types were designated as Sd.Kfz.161/1. In some documents the model is called F2/G.

Transitional model

The German T-4 G tank was an improved version of the F2 with changes to save metal through the use of progressive frontal armor, thicker at the base. The frontal glacis was reinforced with a new 30mm plate, increasing the thickness to a total of 80mm. This was enough to successfully counter the Soviet 76 mm gun and 76.2 mm anti-tank gun. At first they decided to bring only half of production to this standard, but in January 1943 Adolf Hitler personally ordered a complete transition. However, the weight of the car increased to 23.6 tons, revealing limited opportunities chassis and transmissions.

The German T-4 tank has undergone significant changes inside. Turret inspection slits have been eliminated, engine ventilation and ignition at low temperatures improved, additional holders for spare wheels and brackets for track links on the glacis were installed. They also served as temporary protection. The headlights were updated, the armored dome was strengthened and modified.

Later versions in the spring of 1943 added side armor on the hull and turret, as well as smoke grenade launchers. But most importantly, a new, more powerful KwK 40L/48 gun has appeared. After the production of 1,275 standard and 412 improved tanks, production shifted towards the Ausf.H model.

Main version

The German T-4 N tank (photo below) was equipped with a new long-barreled KwK 40L/48 gun. Further changes concerned ease of production - the side inspection slots were removed, and spare parts common to the Panzer III were used. In total, until the next modification of Ausf. J in June 1944, 3774 vehicles were assembled.

In December 1942, Krupp received an order for a tank with fully sloped armor, which due to the additional weight required the development of a new chassis, transmission and possibly engine. However, production began with an updated version of the Ausf.G. The German T-4 tank received a new ZF Zahnradfabrik SSG-76 gearbox, a new set of radio stations (FU2 and 5, and internal communication). The thickness of the frontal armor increased to 80 mm without overlay plates. The weight of the H reached 25 tons in combat gear, and the maximum speed was reduced to 38 km/h, and in real combat conditions to 25 km/h, and much less over rough terrain. By the end of 1943, the German T-4 N tank began to be coated with Zimmerit paste, the air filters were updated, and an anti-aircraft machine for the MG 34 was installed on the turret.

Latest simplified model

The last tank, the German T-4 J, was assembled at the Nibelungwerke in St. Valentin, Austria, as Vomag and Krupp now had other missions, and was subject to simplifications aimed at greater mass production and which rarely found support among the crews. For example, the electric drive of the turret was removed, aiming was done manually, which made it possible to increase the volume of the fuel tank by 200 liters, increasing the operating range to 300 km. Other modifications included the removal of the turret's viewing window, loopholes and anti-aircraft gun in favor of mounting a smoke grenade launcher. "Zimmerit" was no longer used, as were the Schürzen anti-cumulative "skirts", replaced by cheaper mesh panels. The engine radiator housing has also been simplified. The drive has lost one return roller. Two mufflers with flame arresters appeared, as well as a mount for a 2-ton crane. In addition, the SSG 77 transmission from the Panzer III was used, although it was clearly overloaded. Despite these sacrifices, due to constant Allied bombing, deliveries were in jeopardy, and in total only 2,970 tanks were built out of a planned 5,000 by the end of March 1945.

I must say that big number The Panzer IV tanks that survived the Second World War were not lost or scrapped, but were used for their intended purpose in countries such as Bulgaria and Syria. Some of them were equipped with the new Soviet heavy machine gun. They took part in the battles for Golan Heights during the 1965 war and in 1967. Today, German T-4 tanks are part of museum displays and private collections around the world, and dozens of them are still in working order.

Attempts to improve the tank's protection led to the appearance of the "Ausfuhrung G" modification at the end of 1942. The designers knew that the limit of mass that could be withstood chassis, had already been selected, so we had to make a compromise solution - dismantle the 20-mm side screens that were installed on all “fours”, starting with the “E” model, while simultaneously increasing the base armor of the hull to 30 mm, and using the saved weight, install it in the front parts are overhead screens 30 mm thick.

Another measure to increase the tank's security was the installation of removable anti-cumulative screens ("schurzen") 5 mm thick on the sides of the hull and turret; adding screens increased the weight of the vehicle by about 500 kg. In addition, the gun's single-chamber muzzle brake was replaced with a more effective two-chamber one. The appearance of the vehicle also underwent a number of other changes: instead of a rear smoke launcher, built-in blocks of smoke grenade launchers began to be mounted in the corners of the turret, and launch openings were eliminated flares in the driver's and gunner's hatches.

By the end serial production Pz tanks Kpfw IV"Ausfuhrung G" their standard main weapon became a 75-mm gun with a barrel length of 48 calibers, the commander's cupola hatch became single-leaf. The PzKpfw IV Ausf.G tanks of later production are almost identical in appearance to the early vehicles of the Ausf.N modification. From May 1942 to June 1943, 1687 tanks of the Ausf.G model were manufactured, an impressive figure considering that in five years, from the end of 1937 to the summer of 1942, 1300 PzKpfw IV of all modifications were built (Ausf.A -F2), chassis No. - 82701-84400.

In 1944 it was manufactured tank PzKpfw IV Ausf.G with hydrostatic drive of the drive wheels. The drive design was developed by specialists from the Tsanradfabrik company in Augsburg. The main Maybach engine drove two oil pumps, which in turn activated two hydraulic motors connected by output shafts to the drive wheels. All power point was located in the rear part of the hull, respectively, and the drive wheels had a rear location, rather than the front one that is usual for the PzKpfw IV. The speed of the tank was controlled by the driver, controlling the oil pressure created by the pumps.

After the war, the experimental machine came to the USA and was tested by specialists from the Vickers company from Detroit, this company at that time was engaged in work in the field of hydrostatic drives. The tests had to be interrupted due to material failures and a lack of spare parts. Currently, the PzKpfw IV Ausf.G tank with hydrostatic drive wheels is on display in the US Army Tank Museum, Aberdeen, USA. Maryland.

Tank PzKpfw IV Ausf.H (Sd.Kfz. 161/2)

The installation of a long-barreled 75 mm gun turned out to be a rather controversial measure. The gun led to excessive overload of the front part of the tank, the front springs were under constant pressure, and the tank acquired a tendency to sway even when moving on a flat surface. It was possible to get rid of the unpleasant effect with the “Ausfuhrung H” modification, which was put into production in March 1943.

On tanks of this model, the integral armor of the frontal part of the hull, superstructure and turret was strengthened to 80 mm. The PzKpfw IV Ausf.H tank weighed 26 tons and even despite the use of the new SSG-77 transmission, its characteristics turned out to be lower than those of the “fours” of previous models, so the speed of movement over rough terrain decreased by no less than 15 km, the specific pressure on the ground, the acceleration characteristics of the vehicle dropped. On experimental tank The PzKpfw IV Ausf.H was tested with a hydrostatic transmission, but tanks with such a transmission did not go into mass production.

During the production process, many minor modifications were introduced to the Ausf.H model tanks, in particular, they began to install all-steel rollers without rubber, the shape of the drive wheels and idlers changed, a turret for the MG-34 anti-aircraft machine gun appeared on the commander's cupola ("Fligerbeschussgerat 42" - installation of an anti-aircraft machine gun), the tower embrasures for firing pistols and the hole in the roof of the tower for launching signal flares were eliminated.

Ausf.H tanks were the first "fours" to use Zimmerit antimagnetic coating; Only the vertical surfaces of the tank were supposed to be covered with zimmerit, but in practice the coating was applied to all surfaces that could be reached by an infantryman standing on the ground; on the other hand, there were also tanks on which only the forehead of the hull and superstructure were covered with zimmerit. Zimmerit was applied both in factories and in the field.

Tanks of the Ausf.H modification became the most popular among all PzKpfw IV models, 3,774 of them were built, production ceased in the summer of 1944. Factory chassis numbers - 84401-89600, some of these chassis served as the basis for the construction of assault guns.

Tank PzKpfw IV Ausf.J (Sd.Kfz.161/2)

The last model launched into the series was the modification "Ausfuhrung J". Vehicles of this variant began to enter service in June 1944. From a design point of view, the PzKpfw IV Ausf.J represented a step back.

Instead of an electric drive for turning the turret, a manual one was installed, but it became possible to install an additional fuel tank with a capacity of 200 liters. The increase in the cruising range on the highway from 220 km to 300 km (on the off-road - from 130 km to 180 km) due to the placement of additional fuel seemed extremely important decision, since panzer divisions increasingly played the role of “fire brigades”, which were transferred from one sector of the Eastern Front to another.

An attempt to somewhat reduce the weight of the tank was the installation of welded wire anti-cumulative screens (such screens were called “Tom screens”, after the surname of General Tom). Such screens were installed only on the sides of the hull, and the previous screens made of sheet steel remained on the towers. On tanks of late production, three rollers were installed instead of four, and vehicles were also produced with steel road wheels without rubber.

Almost all modifications were aimed at reducing the labor intensity of manufacturing tanks, including: the elimination of all embrasures on the tank for firing pistols and extra viewing slots (only the driver's, in the commander's cupola and in the frontal armor plate of the tower remained), installation of simplified towing loops , replacing the muffler with an exhaust system with two simple pipes. Another attempt to improve the vehicle's security was to increase the armor of the turret roof by 18 mm and the rear armor by 26 mm.

Production of PzKpfw IV Ausf.J tanks ceased in March 1945; a total of 1,758 vehicles were built.

By 1944, it became clear that the design of the tank had exhausted all reserves for modernization; a revolutionary attempt to increase the combat effectiveness of the PzKpfw IV by installing a turret from the Panther tank, armed with a 75-mm gun with a barrel length of 70 calibers, was not crowned with success - the chassis turned out to be too overloaded. Before installing the Panther turret, the designers tried to squeeze the Panther cannon into the turret of the PzKpfw IV tank. Installation wooden model The gun showed the complete impossibility of crew members working in the turret due to the tightness created by the breech of the gun. As a consequence of this failure, the idea was born to mount the entire turret from the Panther on the Pz.IV hull.

Due to the constant modernization of tanks during factory repairs, it is not possible to accurately determine how many tanks of one modification or another were built. Very often there were various hybrid options, for example, turrets from Ausf.G were installed on the hulls of the Ausf.D model.

Less is more—at least sometimes. A smaller caliber can indeed sometimes be more effective than a larger caliber - even if at first glance this statement seems paradoxical.

On the threshold of 1942, German designers armored vehicles were under enormous pressure. Over the past few months, they have significantly improved the modification of the existing German T-4 tanks, increasing the thickness of the lower frontal plate to 50mm, as well as equipping the vehicles with additional frontal plates 30mm thick.

Due to the 10% increase in the tank's weight, which now amounted to 22.3 tons, it was necessary to increase the track width from 380 to 400 mm. To do this, it was necessary to make changes to the design of the guides and drive wheels. In the automotive industry, they like to call such improvements a model change—in the case of the T-4, the modification designation changed from “E” to “F.”

However, these improvements were not enough to turn the T-4 into a full-fledged rival to the Soviet T-34. First of all, weak point these vehicles were their weapons. Along with the 88 mm anti-aircraft gun, as well as captured guns from the reserves of the Red Army - 76-mm guns, which the Germans called “rach-boom” - in the autumn and summer seasons, only the 50-mm Pak 38 anti-tank gun proved its effectiveness, since it fired blanks with a tungsten core.

The Wehrmacht leadership was well aware of the existing problems. Back at the end of May 1941, before the attack on the Soviet Union, there was discussion about urgently equipping the T-4 tank with a Pak 38 cannon, which was supposed to replace the short 75-mm KwK 37 tank gun, called “Stummel” (Russian cigarette butt). The caliber of the Pak 38 was only two-thirds larger than that of the KwK 37.

Due to the length of the gun at 1.8 m, it was impossible to impart sufficient acceleration to the shells, since their initial speed was only 400-450 m/s. The initial speed of Pak 38 projectiles, despite the fact that the gun caliber was only 50 mm, reached more than 800 m/s, and later almost 1200 m/s.

In mid-November 1941, the first prototype of the T-4 tank, equipped with a Pak 38 cannon, was supposed to be ready. However, shortly before that it was discovered that the envisaged modification of the T-4, which was considered a temporary solution on the way to creating a tank capable of resisting the T-34 tank, impossible to implement: Germany did not have enough tungsten to begin mass production of ingots.

On November 14, 1941, a meeting was held at the Fuhrer's headquarters that cost German engineers a quiet Christmas. Because Hitler ordered a complete reorganization of the production of armored vehicles as soon as possible. From now on, it was planned to produce only four types of machines: light reconnaissance tanks, medium battle tanks based on the previous T-4, new heavy tanks ordered for production at the end of June 1941, T-6 Tiger tanks, as well as additional “heavy” tanks.

Four days later, an order was given to develop a new 75 mm gun, the barrel of which was lengthened from 1.8 m to 3.2 m and which was supposed to serve as a replacement for the Stummel. The initial velocity of the projectile increased from 450 to 900 m/s - this was enough to destroy any T-34 from a distance of 1000-1500 m, even using high-explosive shells.

At the same time, there were also tactical changes. Until now, T-3 tanks formed the basis of the combat equipment of German tank divisions. They had to fight enemy tanks while more heavy tanks T-4s were initially developed as auxiliary vehicles for destroying targets that small-caliber guns could not cope with. However, even in battles against French tanks It turned out that only the T-4 could become a serious opponent.

Every German tank regiment nominally had 60 T-3 tanks and 48 T-4 tanks, as well as other tracked vehicles of a lighter design, some of which were produced in the Czech Republic. However, in fact, on the entire eastern front on July 1, 1941, only 551 T-4 tanks were at the disposal of the 19 fighting tank divisions. Despite the fact that a continuous supply of armored vehicles in the amount of about 40 vehicles per month was carried out from factories in Germany for the three army groups participating in the fighting in the Soviet Union, due to war-related supply interruptions, the number of tanks increased by the spring of 1942 only up to 552.

Nevertheless, according to Hitler's decision, T-4 tanks, which in the past were auxiliary vehicles, were to become the main combat vehicles of tank divisions. This also affected the subsequent modification of German combat vehicles, which at that time was at the development stage, namely the T-5 tank, known as the “Panther”.

This model, which began to be developed back in 1937, was put into production on November 25, 1941 and managed to gain experience in countering T-34 tanks. It was the first German tank to have front and side armor plates mounted at an angle. However, it was clear that the supply of tanks of this model in more or less sufficient quantities could not be realized earlier than 1943.

Meanwhile, T-4 tanks had to cope with the role of the main combat vehicles. Engineers from companies involved in the development of armored vehicles, primarily Krupp in Essen and Steyr-Puch in St. Valentin (Lower Austria), managed to increase production by the new year and at the same time reorient it to the production of the F2 model, equipped with an extended Kwk gun 40, supplied to the front since March 1942. Earlier, in January 1942, the production of 59 T-4 tanks per month for the first time exceeded the established norm of 57 tanks.

Now the T-4 tanks were approximately equal in artillery to the T-34 tanks, but were still inferior to the powerful Soviet cars in mobility. But at that time, another existing drawback was more important - the number of cars produced. For the entire 1942, 964 T-4 tanks were produced, and only half of them were equipped with an extended cannon, while the T-34 was produced in quantities of more than 12 thousand vehicles. And here even new guns could not change anything.

The Maybach HL 120TR 12-cylinder carburetor engine (3000 rpm) had a power of 300 hp. With. and allowed the tank to reach a maximum speed on the highway of up to 40 - 42 km/h.

All Pz Kpfw IV tanks had a 75 mm caliber tank gun (7.5 cm in German terminology). In series from modification A to F1, short-barreled 7.5cm KwK37 L/24 guns were installed initial speed armor-piercing projectile 385 m/s, which were powerless against the armor of Soviet T-34 and KV tanks, as well as against most British and American tanks. Since March 1942, the last vehicles of modification F (175 vehicles designated F2), as well as all tanks of modifications G, H and J, began to be armed with long-barreled 7.5cm KwK40 L/43 or L/48 guns. (The KwK 40 L/48 gun was installed on parts of the G series vehicles, and then on modifications H and J.) Pz Kpfw IV tanks, armed with KwK40 guns with an initial armor-piercing projectile speed of 770 m/s, gained some fire superiority over the T-34 time (2nd half of 1942 - 1943)

Tanks Pz Kpfw IV were also armed with two MG 34 machine guns. In modifications B and C there was no radio operator's machine gun; instead there is a viewing slot and a pistol embrasure.

Combat use of medium tanks Pz Kpfw IV

Before the invasion of France, the troops had 280 Pz Kpfw IV Ausf A, B, C, D tanks.

Before the beginning Operation Barbarossa Germany had 3,582 combat-ready tanks. Consisting of 17 tank divisions deployed against Soviet Union, there were 438 tanks Pz IV Ausf B, C, D, E, F. Soviet tanks The KV and T-34 had an advantage over the German Pz Kpfw IV. Shells from KV and T-34 tanks penetrated the armor of the Pz Kpfw IV at considerable distances. The armor of the Pz Kpfw IV was also penetrated by 45-mm Soviet anti-tank guns and 45-mm guns of light tanks T-26 and BT. And the short-barreled German tank gun could only effectively deal with light tanks. Therefore, during 1941, 348 Pz Kpfw IVs were destroyed on the Eastern Front.

In June 1942 years there were 208 tanks on the Eastern Front Pz Kpfw IV Ausf B, C, D, E, F1 and about 170 Pz Kpfw IV Ausf F2 and Ausf G tanks with a long-barreled gun.

In 1942 tank battalion Pz Kpfw IV should have consisted of four tank companies 22 Pz Kpfw IV each plus eight tanks in the regiment's headquarters company.

Spring 1943

(Pz.III), the power plant is located at the rear, and the power transmission and drive wheels are located at the front. The control compartment housed the driver and gunner-radio operator, firing from a machine gun mounted in a ball joint. The fighting compartment was located in the middle of the hull. A multifaceted welded turret was mounted here, which housed three crew members and installed weapons.

T-IV tanks were produced with the following weapons:

• modifications A-F, assault tank with 75 mm howitzer;
• modification G, tank with a 75-mm cannon with a 43-caliber barrel;
• modifications N-K, a tank with a 75 mm cannon with a barrel length of 48 calibers.

Due to the constant increase in the thickness of the armor, the weight of the vehicle during production increased from 17.1 tons (modification A) to 24.6 tons (modifications NK). Since 1943, to enhance armor protection, armor screens were installed on tanks for the sides of the hull and turret. The long-barreled gun introduced on modifications G, NK allowed the T-IV to withstand enemy tanks of equal weight (a 75-mm sub-caliber projectile at a range of 1000 meters penetrated armor 110 mm thick), but its maneuverability, especially the overweight latest modifications, was unsatisfactory. In total, about 9,500 T-IV tanks of all modifications were produced during the war.

Tank PzKpfw IV. History of creation.

In the 20s and early 30s, the theory of the use of mechanized troops, in particular tanks, developed through trial and error; the views of theorists changed very often. A number of supporters of tanks believed that the appearance of armored vehicles would make positional warfare in the style of battles of 1914-1917 tactically impossible. In turn, the French relied on the construction of well-fortified long-term defensive positions, such as the Maginot Line. A number of experts believed that the main armament of a tank should be a machine gun, and the main task of armored vehicles is to fight enemy infantry and artillery; the most radically thinking representatives of this school considered a battle between tanks pointless, since, supposedly, neither side would be able to cause damage to the other. There was an opinion that the victory in the battle would be won by the side that could destroy the largest number of enemy tanks. Special guns with special shells - anti-tank guns with armor-piercing shells - were considered as the main means of fighting tanks. In fact, no one knew what the nature of hostilities would be in a future war. Experience civil war in Spain also did not clarify the situation.

The Treaty of Versailles prohibited Germany from having tracked combat vehicles, but could not prevent German specialists from working on studying various theories of using armored vehicles, and the creation of tanks was carried out by the Germans in secrecy. When Hitler threw away the restrictions of Versailles in March 1935, the young Panzerwaffe already had all the theoretical developments in the field of application and organizational structure tank regiments.

In mass production under the guise of "agricultural tractors" there were two types of light armed tanks, PzKpfw I and PzKpfw II.
The PzKpfw I tank was considered a training vehicle, while the PzKpfw II was intended for reconnaissance, but it turned out that the “two” remained the most popular tank of the panzer divisions until it was replaced by the PzKpfw III medium tanks, armed with a 37 mm cannon and three machine guns.

The development of the PzKpfw IV tank dates back to January 1934, when the army issued a specification to industry new tank fire support weighing no more than 24 tons, the future vehicle received the official designation Gesch.Kpfw. (75 mm)(Vskfz.618). Over the next 18 months, specialists from Rheinmetall-Borzing, Krupp and MAN worked on three competing designs for the battalion commander's vehicle (Battalionführerswagnen, abbreviated as BW). The VK 2001/K project, presented by the Krupp company, was recognized as the best, with a turret and hull shape similar to the PzKpfw III tank.

However, the VK 2001/K did not go into production, since the military was not satisfied with the six-wheel chassis with medium-diameter wheels on a spring suspension; it needed to be replaced with a torsion bar. The torsion bar suspension, compared to the spring one, ensured smoother movement of the tank and had a greater vertical travel of the road wheels. Krupp engineers, together with representatives of the Arms Procurement Directorate, agreed on the possibility of using an improved design of spring suspension on the tank with eight small-diameter road wheels on board. However, the Krupp company largely had to revise the proposed original design. In the final version, the PzKpfw IV was a combination of the hull and turret of the VK 2001/K with a chassis newly developed by Krupp.

When the Pz.IV tank did not yet exist

The PzKpfw IV tank is designed according to the classic layout with a rear engine. The commander's position was located along the axis of the tower directly under the commander's cupola, the gunner was located to the left of the breech of the gun, and the loader was to the right. In the control compartment, located in the front part of the tank hull, there were workstations for the driver (to the left of the vehicle axis) and the radio operator (to the right). Between the driver's and gunner's seats there was a transmission. Interesting feature The design of the tank was to shift the turret approximately 8 cm to the left of the longitudinal axis of the vehicle, and the engine - 15 cm to the right to allow passage of the shaft connecting the engine and transmission. This design decision made it possible to increase the internal reserved volume on the right side of the hull to accommodate the first shots, which could be most easily reached by the loader. The turret rotation drive is electric.

The suspension and chassis consisted of eight small-diameter road wheels grouped into two-wheeled bogies suspended on leaf springs, drive wheels, sloths installed in the rear of the tank, and four rollers supporting the track. Throughout the entire history of operation of the PzKpfw IV tanks, their chassis remained unchanged, only minor improvements were introduced. The prototype of the tank was manufactured at the Krupp plant in Essen and was tested in 1935-36.

Description of the PzKpfw IV tank

Armor protection.
In 1942, consulting engineers Mertz and McLillan conducted a detailed examination of the captured PzKpfw IV Ausf.E tank, in particular, they carefully studied its armor.

Several armor plates were tested for hardness, all of them were machined. The hardness of the machined armor plates on the outside and inside was 300-460 Brinell.
- The 20 mm thick applied armor plates, which enhance the armor of the hull sides, are made of homogeneous steel and have a hardness of about 370 Brinell. The reinforced side armor is not capable of "holding" 2 pound shells fired from 1000 yards.

On the other hand, shelling of a tank carried out in the Middle East in June 1941 showed that a distance of 500 yards (457 m) can be considered as the limit for effectively hitting a PzKpfw IV in the frontal area with fire from a 2-pounder gun. A report on the armor protection of a German tank prepared in Woolwich notes that “the armor is 10% better than similar treated mechanically English, and in some respects even better homogeneous."

At the same time, the method of connecting armor plates was criticized; a specialist from Leyland Motors commented on his research: “The welding quality is poor, the welds of two of the three armor plates in the area where the projectile hit came apart.”

Power point.
The Maybach engine is designed to operate in moderate climatic conditions, where its characteristics are satisfactory. At the same time, in tropical or highly dusty conditions, it breaks down and is prone to overheating. British intelligence, after studying the PzKpfw IV tank captured in 1942, concluded that engine failures were caused by sand getting into the oil system, distributor, dynamo and starter; air filters are inadequate. Celebrated frequent cases sand getting into the carburetor.

The Maybach engine operating manual requires the use of only 74 octane gasoline with a complete lubricant change after 200, 500, 1000 and 2000 km. Recommended engine speed at normal conditions operation - 2600 rpm, but in hot climates (southern regions of the USSR and North Africa) this number of revolutions does not provide normal cooling. Using the engine as a brake is permissible at 2200-2400 rpm; at a speed of 2600-3000 this mode should be avoided.

The main components of the cooling system were two radiators installed at an angle of 25 degrees to the horizontal. The radiators were cooled by an air flow forced by two fans; The fans are driven by a belt from the main engine shaft. Water circulation in the cooling system was ensured by a centrifuge pump. Air entered the engine compartment through an opening on the right side of the hull, covered by an armored damper, and was exhausted out through a similar opening on the left side.

The synchro-mechanical transmission proved efficient, although pulling force in high gears was low, so 6th gear was used only for highway driving. The output shafts are combined with the braking and turning mechanism into a single device. To cool this device, a fan was installed to the left of the clutch box. The simultaneous release of the steering control levers could be used as an effective parking brake.

On tanks of later versions, the spring suspension of the road wheels was heavily overloaded, but replacing the damaged two-wheeled bogie seemed to be a fairly simple operation. The track tension was regulated by the position of the idler mounted on the eccentric. On the Eastern Front, special track extenders, known as "Ostketten", were used, which improved the maneuverability of tanks in winter months of the year.

An extremely simple but effective device for putting on a slipped track was tested on an experimental PzKpfw IV tank. It was a factory-made tape that had the same width as the tracks and was perforated to engage with the drive wheel ring gear. One end of the tape was attached to the slipped track, and the other, after it was passed over the rollers, to the drive wheel. The motor turned on, the drive wheel began to rotate, pulling the tape and the tracks attached to it until the rims of the drive wheel entered the slots on the tracks. The whole operation took a few minutes.

The engine was started by a 24-volt electric starter. Since the auxiliary electric generator saved battery power, it was possible to try to start the engine more times on the “four” than on the PzKpfw III tank. In case of starter failure, or when the lubricant thickened in severe frost, an inertial starter was used, the handle of which was connected to the engine shaft through a hole in the rear armor plate. The handle was turned by two people at the same time; the minimum number of turns of the handle required to start the engine was 60 rpm. Starting the engine from an inertia starter has become commonplace in the Russian winter. The minimum temperature of the engine at which it began to operate normally was t = 50 degrees C with a shaft rotation of 2000 rpm.

To facilitate engine starting in the cold climate of the Eastern Front, a special system was developed known as a "Kuhlwasserubertragung" - a cold water heat exchanger. After starting and warming up to normal temperature engine of one tank, warm water from it was pumped into the cooling system of the next tank, and cold water came to an already running motor - an exchange of coolants between the running and non-running motors took place. After the warm water warmed up the engine somewhat, you could try starting the engine with an electric starter. The "Kuhlwasserubertragung" system required minor modifications to the tank's cooling system.
