Modifications of the tank t 4. Medium German tank Tiger Panzerkampfwagen IV

The production of this tank, created by Krupp, began in 1937 and continued throughout the Second World War.
Like the T-III tank (Pz.III), power point is located at the rear, and the power transmission and drive wheels are at the front. The department of management housed a driver and a gunner-radio operator, firing from a machine gun mounted in a ball bearing. The fighting compartment was in the middle of the hull. A multifaceted welded tower, 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, a tank with a 75-mm cannon with a barrel length of 43 caliber;
- 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 (modification H-K). Since 1943, to enhance armor protection, armored screens were installed on the sides of the hull and turret. The long-barreled gun introduced on modifications G, H-K allowed the T-IV to withstand enemy tanks of equal weight (a 75-mm sub-caliber projectile pierced 110-mm armor at a distance of 1000 meters), but its maneuverability, especially overweighted latest modifications, was unsatisfactory. In total, about 9,500 T-IV tanks of all modifications were produced during the war years.

Tank PzKpfw IV. History of creation.

In the 1920s and early 1930s, the theory of the use of mechanized troops, in particular tanks, was developed by trial and error, the views of theorists changed very often. A number of tank supporters believed that the appearance of armored vehicles would make positional warfare in the style of fighting 1914-1917 impossible from a tactical point of view. 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 the tank should be a machine gun, and the main task of armored vehicles is to fight the infantry and artillery of the enemy, the most radically thinking representatives of this school considered the battle between tanks to be pointless, since, allegedly, neither side could inflict damage on the other. There was an opinion that the side that could destroy the largest number of enemy tanks would win the battle. As the main means of fighting tanks, special weapons with special shells were considered - anti-tank guns with armor-piercing shells. In fact, no one knew what the nature of hostilities would be in future war. An experience civil war in Spain also did not clarify the situation.

The Treaty of Versailles forbade Germany to have combat tracked vehicles, but could not prevent German specialists from working on studying various theories of the use of armored vehicles, and the creation of tanks was carried out by the Germans in secrecy. When in March 1935 Hitler abandoned the restrictions of Versailles, the young "Panzerwaffe" already had all the theoretical studies in the field of application and organizational structure of tank regiments.

There were two types of light armed tanks PzKpfw I and PzKpfw II under the guise of "agricultural tractors" in serial production.
Tank PzKpfw I was considered a training vehicle, while the PzKpfw II was intended for reconnaissance, but it turned out that the "two" remained the most massive tank of panzerdivisions until it was replaced by medium tanks PzKpfw III, armed with a 37-mm cannon and three machine guns.

The beginning of the development of the PzKpfw IV tank dates back to January 1934, when the army gave the industry a specification for a new fire support tank 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 projects for the battalion commander's vehicle ("battalionführerswagnen" abbreviated as BW). The VK 2001/K project, presented by Krupp, was recognized as the best project, the shape of the turret and hull is close to the PzKpfw III tank.

However, the VK 2001 / K machine did not go into series, because the military was not satisfied with the six-support undercarriage with medium-diameter wheels on spring suspension, it needed to be replaced with a torsion bar. The torsion bar suspension, compared to the spring suspension, provided a smoother movement of the tank and had a greater vertical travel of the road wheels. Krupp engineers, together with representatives of the Arms Procurement Administration, agreed on the possibility of using an improved spring suspension design with eight small-diameter road wheels on board on the tank. However, Krupp had to largely 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 vehicle with a chassis newly developed by Krupp.

The PzKpfw IV tank was designed according to the classic layout scheme with a rear engine. The commander's place was located along the axis of the tower directly under the commander's cupola, the gunner was located to the left of the cannon breech, the loader was to the right. In the control compartment, located in front of the tank hull, there were jobs for the driver (to the left of the vehicle axis) and the radio operator's gunner (to the right). Between the driver's seat and the arrow was the transmission. An interesting feature The design of the tank was to shift the turret by about 8 cm to the left of the longitudinal axis of the vehicle, and the engine - by 15 cm to the right to pass the shaft connecting the motor and transmission. Such a constructive solution made it possible to increase the internal reserved volume on the right side of the hull for the placement of the first shots, which the loader could most easily get. Turret turn drive - electric.

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

Description of the tank PzKpfw IV

armor protection.
In 1942, consulting engineers Mertz and McLillan conducted a detailed survey 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 outside and inside was 300-460 Brinell.
- Overhead armor plates with a thickness of 20 mm, with which the armor of the hull sides is reinforced, are made of homogeneous steel and have a hardness of about 370 Brinell. The reinforced side armor is unable to "hold" 2-pound projectiles fired from 1000 yards.

On the other hand, a tank attack conducted in the Middle East in June 1941 showed that a distance of 500 yards (457 m) can be considered as the limit for effective frontal engagement of a PzKpfw IV with a 2-pounder gun. A report prepared in Woolwich on the study of armor protection of a German tank notes that "armor is 10% better than similarly processed mechanically English, and in some respects better homogeneous."

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

Power point.

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

The Maybach engine manual requires the use of gasoline only with an octane rating of 74 with a complete lubricant change after 200, 500, 1000 and 2000 km of run. Recommended engine speed at normal conditions operation - 2600 rpm, but in a hot climate (southern regions of the USSR and North Africa), this speed does not provide normal cooling. The use of 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 horizon. The radiators were cooled by an airflow forced by two fans; fan drive - belt driven from the main motor shaft. The circulation of water in the cooling system was provided by a centrifuge pump. Air entered the engine compartment through a hole covered with an armored shutter from the right side of the hull and was thrown out through a similar hole on the left side.

The synchro-mechanical transmission proved to be effective, although pulling power in high gears was low, so 6th gear was only used on the highway. 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 disengagement 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 tension of the caterpillar was regulated by the position of the sloth mounted on the eccentric. On the Eastern Front special track expanders, known as "Ostketten", were used, which improved the patency of tanks in the winter months of the year.

An extremely simple but effective device for dressing a jumped caterpillar was tested on experimental tank PzKpfw IV. It was a factory-made tape that had the same width as the tracks, and perforation for engagement with the gear rim of the drive wheel. One end of the tape was attached to the track that had come off, the other, after it was passed over the rollers, to the drive wheel. The motor was turned on, the drive wheel began to rotate, pulling the tape and the tracks fastened to it until the rims of the drive wheel entered the slots on the tracks. The whole operation took several 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 the event of a starter failure, or when the grease thickened in severe frost, an inertial starter was used, the handle of which was connected to the engine shaft through a hole in the aft 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 inertial starter has become commonplace in the Russian winter. The minimum temperature of the engine, at which it started to work normally, was t = 50 ° C when the shaft rotated 2000 rpm.

To facilitate starting the engine in the cold climate of the Eastern Front, a special system was developed, known as the "Kuhlwasserubertragung" - a cold water heat exchanger. After starting up 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 working motor - there was an exchange of refrigerants between the working and non-working motors. After the warm water warmed up the motor a little, it was possible to try to start the engine with an electric starter. The "Kuhlwasserubertragung" system required minor modifications to the tank's cooling system.

Modern battle tanks of Russia and the world photos, videos, pictures to watch online. This article gives an idea of ​​the modern tank fleet. It is based on the classification principle used in the most authoritative reference book to date, but in a slightly modified and improved form. And if the latter in its original form can still be found in the armies of a number of countries, then others have already become a museum exhibit. And all for 10 years! To follow in the footsteps of the Jane's guide and not consider this combat vehicle (quite by the way, curious in design and fiercely discussed at the time), which formed the basis of the tank fleet of the last quarter of the 20th century, the authors considered it unfair.

Films about tanks where there is still no alternative to this type of weapon ground forces. The tank was and probably will remain a modern weapon for a long time due to the ability to combine such seemingly contradictory qualities as high mobility, powerful weapons and reliable crew protection. These unique qualities of tanks continue to be constantly improved, and the experience and technologies accumulated over decades predetermine new frontiers of combat properties and military-technical achievements. In the age-old confrontation "projectile - armor", as practice shows, protection from a projectile is being improved more and more, acquiring new qualities: activity, multi-layeredness, self-defense. At the same time, the projectile becomes more accurate and powerful.

Russian tanks are specific in that they allow you to destroy the enemy from a safe distance, have the ability to perform quick maneuvers on impassable roads, contaminated terrain, can “walk” through the territory occupied by the enemy, seize a decisive bridgehead, induce panic in the rear and suppress the enemy with fire and caterpillars . The war of 1939-1945 became the most difficult test for all mankind, since almost all countries of the world were involved in it. It was the battle of the titans - the most unique period that theorists argued about in the early 1930s and during which tanks were used in large numbers by almost all the warring parties. At this time, a "check for lice" and a deep reform of the first theories of the use of tank troops took place. And it is the Soviet tank forces all of which are the most affected.

Tanks in battle that became a symbol of the past war, the backbone of the Soviet armored forces? Who created them and under what conditions? How did the USSR, which lost most of his European territories and with difficulty recruiting tanks for the defense of Moscow, was he able to release powerful tank formations on the battlefield already in 1943? This book, which tells about the development of Soviet tanks "in the days of trials", from 1937 to early 1943. When writing the book, materials from the archives of Russia and private collections of tank builders were used. There was a period in our history that was deposited in my memory with some depressing feeling. It began with the return of our first military advisers from Spain, and stopped only at the beginning of forty-third, - said the former general designer of self-propelled guns L. Gorlitsky, - there was some kind of pre-stormy state.

Tanks of the Second World War, it was M. Koshkin, almost underground (but, of course, with the support of "the wisest of the wise leader of all peoples"), who was able to create the tank that, a few years later, would shock German tank generals. And what’s more, he didn’t just create it, the designer managed to prove to these stupid military men that it was his T-34 that they needed, and not just another wheeled-tracked “highway”. The author is in slightly different positions that he formed after meeting with the pre-war documents RGVA and RGAE Therefore, working on this segment of the history of the Soviet tank, the author will inevitably contradict something "generally accepted". this work describes history Soviet tank building in the most difficult years- from the beginning of a radical restructuring of the entire activity of design bureaus and people's commissariats as a whole, during a frantic race to equip new tank formations of the Red Army, the transfer of industry to wartime rails and evacuation.

Tanks Wikipedia the author wants to express his special gratitude for the help in the selection and processing of materials to M. Kolomiyets, and also to thank A. Solyankin, I. Zheltov and M. Pavlov, the authors of the reference publication "Domestic armored vehicles. XX century. 1905 - 1941" because this book helped to understand the fate of some projects, unclear before. I would also like to recall with gratitude those conversations with Lev Izraelevich Gorlitsky, the former Chief Designer of UZTM, which helped to take a fresh look at the entire history of the Soviet tank during the Great Patriotic War of the Soviet Union. Today, for some reason, it is customary to talk about 1937-1938 in our country. only from the point of view of repressions, but few people remember that it was during this period that those tanks were born that became legends of the wartime ... "From the memoirs of L.I. Gorlinkogo.

Soviet tanks, a detailed assessment of them at that time sounded from many lips. Many old people recalled that it was from the events in Spain that it became clear to everyone that the war was getting closer to the threshold and it was Hitler who would have to fight. In 1937, mass purges and repressions began in the USSR, and against the backdrop of these difficult events, the Soviet tank began to turn from a "mechanized cavalry" (in which one of its combat qualities protruded by reducing others) into a balanced combat vehicle, which simultaneously had powerful weapons, sufficient to suppress most targets, good cross-country ability and mobility with armor protection, capable of maintaining its combat effectiveness when shelling a potential enemy with the most massive anti-tank weapons.

Large tanks were recommended to be added to the composition only special tanks- floating, chemical. The brigade now had 4 separate battalions of 54 tanks each and was reinforced by the transition from three-tank platoons to five-tank ones. In addition, D. Pavlov justified the refusal to form in 1938 to the four existing mechanized corps three more additionally, believing that these formations are immobile and difficult to control, and most importantly, they require a different organization of the rear. The tactical and technical requirements for promising tanks, as expected, have been adjusted. In particular, in a letter dated December 23 to the head of the design bureau of plant No. 185 named after. CM. Kirov, the new chief demanded to strengthen the armor of new tanks so that at a distance of 600-800 meters (effective range).

The latest tanks in the world when designing new tanks, it is necessary to provide for the possibility of increasing the level of armor protection during modernization by at least one step ... "This problem could be solved in two ways. Firstly, by increasing the thickness of the armor plates and, secondly," by using increased armor resistance". It is easy to guess that the second way was considered more promising, since the use of specially hardened armor plates, or even two-layer armor, could, while maintaining the same thickness (and the mass of the tank as a whole), increase its durability by 1.2-1.5 It was this path (the use of specially hardened armor) that was chosen at that moment to create new types of tanks.

Tanks of the USSR at the dawn of tank production, armor was most massively used, the properties of which were identical in all directions. Such armor was called homogeneous (homogeneous), and from the very beginning of the armor business, the craftsmen strove to create just such armor, because uniformity ensured stability of characteristics and simplified processing. However, at the end of the 19th century, it was noticed that when the surface of the armor plate was saturated (to a depth of several tenths to several millimeters) with carbon and silicon, its surface strength increased sharply, while the rest of the plate remained viscous. So heterogeneous (heterogeneous) armor came into use.

In military tanks, the use of heterogeneous armor was very important, since an increase in the hardness of the entire thickness of the armor plate led to a decrease in its elasticity and (as a result) to an increase in brittleness. Thus, the most durable armor, other things being equal, turned out to be very fragile and often pricked even from bursts of high-explosive fragmentation shells. Therefore, at the dawn of armor production in the manufacture of homogeneous sheets, the task of the metallurgist was to achieve the highest possible hardness of the armor, but at the same time not to lose its elasticity. Surface-hardened by saturation with carbon and silicon armor was called cemented (cemented) and was considered at that time a panacea for many ills. But cementation is a complex, harmful process (for example, processing a hot plate with a jet of lighting gas) and relatively expensive, and therefore its development in a series required high costs and an increase in production culture.

Tank of the war years, even in operation, these hulls were less successful than homogeneous ones, since for no apparent reason cracks formed in them (mainly in loaded seams), and it was very difficult to put patches on holes in cemented slabs during repairs. But it was still expected that a tank protected by 15-20 mm cemented armor would be equivalent in terms of protection to the same, but covered with 22-30 mm sheets, without a significant increase in mass.
Also, by the mid-1930s, in tank building, they learned how to harden the surface of relatively thin armor plates by uneven hardening, known since the end of the 19th century in shipbuilding as the "Krupp method". Surface hardening led to a significant increase in the hardness of the front side of the sheet, leaving the main thickness of the armor viscous.

How tanks shoot videos up to half the thickness of the plate, which, of course, was worse than carburizing, since despite the fact that the hardness of the surface layer was higher than during carburizing, the elasticity of the hull sheets was significantly reduced. So the "Krupp method" in tank building made it possible to increase the strength of armor even somewhat more than carburizing. But the hardening technology that was used for sea armor of large thicknesses was no longer suitable for relatively thin tank armor. Before the war, this method was almost never used in our serial tank building due to technological difficulties and relatively high cost.

Combat use of tanks The most developed for tanks was the 45-mm tank gun mod 1932/34. (20K), and before the event in Spain, it was believed that its power was enough to perform most tank tasks. But the fighting in Spain showed that the 45-mm gun can only satisfy the task of fighting enemy tanks, since even the shelling of manpower in the conditions of mountains and forests turned out to be ineffective, and it was only possible to disable a dug-in enemy firing point in the event of a direct hit. Shooting at shelters and bunkers was ineffective due to the small high-explosive action of a projectile weighing only about two kg.

Types of tanks photo so that even one hit of a projectile reliably disables an anti-tank gun or machine gun; and thirdly, to increase the penetrating effect of a tank gun on the armor of a potential enemy, as in the example French tanks(already having an armor thickness of the order of 40-42 mm) it became clear that the armor protection of foreign combat vehicles tends to be significantly strengthened. There was a right way to do this - increasing the caliber of tank guns and simultaneously increasing the length of their barrel, since a long gun of a larger caliber fires heavier projectiles at a higher muzzle velocity over a greater distance without correcting the pickup.

The best tanks in the world had a large caliber gun, also has big sizes breech, significantly more weight and increased recoil reaction. And this required an increase in the mass of the entire tank as a whole. In addition, the placement of large shots in the closed volume of the tank led to a decrease in the ammunition load.
The situation was aggravated by the fact that at the beginning of 1938 it suddenly turned out that there was simply no one to give an order for the design of a new, more powerful tank gun. P. Syachintov and his entire design team were repressed, as well as the core of the Bolshevik Design Bureau under the leadership of G. Magdesiev. Only the group of S. Makhanov remained at liberty, who from the beginning of 1935 tried to bring his new 76.2-mm semi-automatic single gun L-10, and the team of plant No. 8 slowly brought the "forty-five".

Photos of tanks with names The number of developments is large, but in mass production in the period 1933-1937. not a single one was accepted ... "In fact, none of the five air-cooled tank diesel engines, which were worked on in 1933-1937 in the engine department of plant No. 185, was brought to the series. Moreover, despite the decisions on most upper levels on the transition in tank building exclusively to diesel engines This process was hampered by a number of factors. Of course, diesel had significant efficiency. It used less fuel per unit of power per hour. Diesel fuel is less prone to ignition, since the flash point of its vapors was very high.

Even the most finished of them, the MT-5 tank engine, required reorganization of engine production for serial production, which was expressed in the construction of new workshops, the supply of advanced foreign equipment (there were no machine tools of the required accuracy yet), financial investments and strengthening personnel. It was planned that in 1939 this diesel engine with a capacity of 180 hp. will go to mass-produced tanks and artillery tractors, but due to investigative work to find out the causes of tank engine accidents, which lasted from April to November 1938, these plans were not fulfilled. The development of a slightly increased six-cylinder gasoline engine No. 745 with a power of 130-150 hp was also started.

Brands of tanks with specific indicators that suited the tank builders quite well. Tank tests were carried out according to a new methodology, specially developed at the insistence of the new head of the ABTU D. Pavlov in relation to combat service in war time. The basis of the tests was a run of 3-4 days (at least 10-12 hours of daily non-stop traffic) with a one-day break for technical inspection and restoration work. Moreover, repairs were allowed to be carried out only by field workshops without the involvement of factory specialists. This was followed by a "platform" with obstacles, "bathing" in the water with an additional load, simulating an infantry landing, after which the tank was sent for examination.

Super tanks online after the improvement work seemed to remove all claims from the tanks. And general course tests confirmed the fundamental correctness of the main design changes - an increase in displacement by 450-600 kg, the use of the GAZ-M1 engine, as well as the Komsomolets transmission and suspension. But during the tests, numerous minor defects again appeared in the tanks. Chief designer N. Astrov was suspended from work and was in custody and under investigation for several months. In addition, the tank received a new improved protection turret. The modified layout made it possible to place on the tank a larger ammunition load for a machine gun and two small fire extinguishers (before there were no fire extinguishers on small tanks of the Red Army).

US tanks as part of modernization work, on one serial model of the tank in 1938-1939. the torsion bar suspension developed by the designer of the Design Bureau of Plant No. 185 V. Kulikov was tested. It was distinguished by the design of a composite short coaxial torsion bar (long monotorsion bars could not be used coaxially). However, such a short torsion bar did not show good enough results in tests, and therefore the torsion bar suspension did not immediately pave its way in the course of further work. Obstacles to be overcome: rises not less than 40 degrees, vertical wall 0.7 m, overlapping ditch 2-2.5 m.

Youtube about tanks work on the production of prototypes of D-180 and D-200 engines for reconnaissance tanks is not being carried out, jeopardizing the production of prototypes. 10-1), as well as the amphibious tank version (factory designation 102 or 10-2), are a compromise solution, since it is not possible to fully meet the requirements of the ABTU.Variant 101 was a tank weighing 7.5 tons with a hull according to the type of hull, but with vertical side sheets of case-hardened armor 10-13 mm thick, because: "Sloped sides, causing serious weighting of the suspension and hull, require a significant (up to 300 mm) broadening of the hull, not to mention the complication of the tank.

Video reviews of tanks in which the power unit of the tank was planned to be based on the 250-horsepower MG-31F aircraft engine, which was mastered by the industry for agricultural aircraft and gyroplanes. Gasoline of the 1st grade was placed in a tank under the floor of the fighting compartment and in additional onboard gas tanks. The armament fully met the task and consisted of coaxial machine guns DK caliber 12.7 mm and DT (in the second version of the project even ShKAS appears) caliber 7.62 mm. The combat weight of a tank with a torsion bar suspension was 5.2 tons, with a spring suspension - 5.26 tons. The tests were carried out from July 9 to August 21 according to the methodology approved in 1938, with special attention paid to tanks.

The German army entered the Second World War with a rather strange situation in the system of tank weapons. The medium tank Pz.Kpfw.III, which was created as the main one, in fact at that time turned out to be the smallest in the Wehrmacht. As for the other medium tank, the Pz.Kpfw.IV, it was designed as a support vehicle, but at the same time, there were almost four times more such vehicles in the troops than the Pz.Kpfw.III. The German industry was able to equalize the number of tanks of these two types in the army only at the very end of 1939. By this time, the series had already gone a new version support tank - Pz.Kpfw.IV Ausf.D, moreover, in a sense, it became a return to the original concept.

Return of the course machine gun

The spring of 1938 turned out to be decisive for the further fate of the Pz.Kpfw.IV. The fact is that the 6th department of the Arms Administration seriously thought about removing the brainchild of the Krupp concern from the production program. Instead of the Pz.Kpfw.IV, it was supposed to create a support tank based on the Pz.Kpfw.III, thus unifying both medium tanks in terms of the main components and assemblies.

On the one hand, the idea was sound. However, it should be noted that the Pz.Kpfw.III at that time was far from experiencing better times. And the production of the Pz.Kpfw.IV was not without problems, but it still went on, and the Krupp designers got into the weight category determined by the customers from the first time.

Thus, when on May 2, 1938, Erich Wolfert, Krupp's chief engineer, sharply criticized the idea of ​​\u200b\u200bcombining two tanks on one platform, victory was on his side. The 6th department of the Armaments Directorate was forced to give in, because behind Wolfert was not only an industrial giant, but also common sense.

The lesson, however, did not benefit, and the 6th Department of the Armaments Directorate continued to compete with the idea of ​​​​a single chassis for two types of tanks throughout the war. This impulse, one of the initiators of which was Heinrich Ernst Kniepkamp, ​​with enviable constancy turned into a rake race, and each time the proper conclusions were not drawn from what had happened before.

Pz.Kpfw.IV Ausf.D in original configuration. In metal, the car looked a little different.

The requirements for a support tank, meanwhile, continued to grow. Back in early January 1938, discussions began on the characteristics of the fourth modification of the tank, which received the designation 4.Serie / B.W.

One of the first items on the agenda was the return to the place of the course machine gun. Someone upstairs finally realized that you can’t even shoot much from the pistol port, let alone hit somewhere. It was decided to use the Kugelblende 30 mount, developed for the Z.W.38 (future Pz.Kpfw.III Ausf.E). It had much more successful protection than the Pz.Kpfw.IV Ausf.A ball mount. In connection with the return of the course machine gun, the front plate of the turret box again received a characteristic step.

On March 10, 1938, a meeting was held in Berlin, where employees of the Krupp concern and the 6th department of the Arms Administration discussed the possibility of strengthening the tank's armor. The thickness of the side armor of the hull, turret box and turret, which was 14.5 mm, was considered insufficient. It was necessary to increase it to 20 mm, so that at long distances the tank would not be hit by the fire of 20 mm automatic guns. In addition, the military asked to increase the thickness of the bottom from 8 to 10 mm.

The answer to the new requirements came on April 12. According to the calculations of engineers, the increase in the thickness of the armor increased the combat weight of the tank by 1256 kg, to almost 20 tons. This was followed by changes in individual elements of the hull. The hatches in the area of ​​the support rollers received a different shape, the air intakes of the engine compartment have changed. At the end of April, tracks with increased teeth were developed, and the number of suspension travel stops was increased to five per side (one each for the three front bogies and two for the rear).

Certain changes were made to the design of the tower. First of all, the armor of the gun system was reworked. The fact is that the previously used design turned out to be very vulnerable to enemy fire. A bullet or a fragment of a projectile, falling into the gap between the elements of the armor, could well jam the gun in a vertical plane. At the end of May 1938, development began new protection for the gun. The new armor of the system was located on the outside of the tower and coped with its task much better. The thickness of the armor has been increased to 35 mm.

In addition, viewing devices on the side hatches and sides of the tower were replaced.

When, on July 4, 1938, a contract was finally signed with the Krupp concern for the manufacture of tanks of the 4.Serie / B.W. modification, the car changed quite a lot. According to the contract, the factories of Grusonwerk, one of the divisions of Krupp, were to produce 200 tanks of this series. In October, the contract was extended. The SS troops ordered 48 tanks, which received the designation 5.Serie/B.W. In fact, they were no different from the 4.Serie/B.W. By the way, in the end, these vehicles did not get into the SS unit, since it was decided to order StuG III assault self-propelled guns instead.

Tanks of the 4th and 5th series received the designation Pz.Kpfw.IV Ausf.D. The machines were assigned serial numbers in the range 80501–80748.

Based on the experience of the first two campaigns

Serial production of the Pz.Kpfw.IV Ausf.D began in October of 1939. Unlike the Pz.Kpfw.III, whose production was accelerated by manufacturers, there were no special breakthroughs in the production of support tanks. Until the end of 1939, 45 tanks were assembled, later the volumes averaged 20-25 vehicles per month. In total, by May 1, 1940, 129 machines of this modification were manufactured.

Meanwhile, back in March of 1939, it was decided that in the future the Wehrmacht would continue to order these tanks, and the vehicles of the 6th series (6.Serie / B.W.) would henceforth be designated as Pz.Kpfw.IV Ausf.E. A new contract for the manufacture of 223 tanks of this type was signed in July 1939. In general, this tank was supposed to repeat its predecessor, but already in May some changes began to appear.

To begin with, it was decided to change the driver’s viewing device, which did not change from the Pz.Kpfw.IV Ausf.B, to the Fahrersehklappe 30. This device was distinguished by the fact that instead of massive parts going up and down, it used an “eyelash” thick 30 mm. It covered the viewing slot covered with glass block much more reliably, and its design turned out to be much simpler.

A rather large ventilation hatch from the roof of the tower also disappeared, and a fan appeared instead. A hatch for signal flags has moved to the place of the periscope device. The shape of the commander's cupola has also changed.

It became clear after the Polish campaign in September 1939 that the Ausf.E would not go into production as planned, and that the Ausf.D would also undergo certain changes. The fact is that Polish troops massively used 37-mm anti-tank guns Armata przeciwpancerna 37 mm wz against German tanks. 36 Bofors. Even though the Polish shells were not of the best quality, they confidently pierced German vehicles in all projections. The strengthening of the frontal part up to 30 mm did not help much here either.

In the autumn of 1939, studies began to be carried out to identify the possibility of additionally loading the Pz.Kpfw.IV with another 1.5 tons of armor and bringing its combat weight to 21.4 tons. Tests have shown that the tank quite easily tolerates such an increase in mass.

On December 18, 1939, the 6th Department of the Ordnance Directorate adjusted the task for 4.Serie / B.W. and 5.Serie/B.W. The last 68 tanks were to receive hulls with front plates reinforced to 50 mm. But by the start of the campaign in France, which began on May 10, 1940, the Pz.Kpfw.IV Ausf.D still continued to be produced with a 30 mm thick front plate.

The very first battles showed that such slowness is extremely reckless. Of course, the 37-mm short-barreled guns that were installed on a number of French tanks, including the FCM 36 and Renault R 35, could not penetrate 30 mm thick frontal armor. But they were not at all the main opponents of German tanks. The French were doing well with anti-tank artillery, and for her armor 30 mm thick was by no means something outrageous. Even worse for the Germans was that a number of French tanks had 47 mm guns as their main armament.

The losses of the Pz.Kpfw.IV in France were even higher than in September 1939 in Poland. Of the 279 Pz.Kpfw.IVs available in units on May 10, 1939, 97, that is, more than a third, were irretrievably lost. The battles of May-June 1940 also showed that the 75-mm short-barreled gun was almost powerless against tanks with anti-cannon armor.

It became clear that the problem must be solved, and solved quickly. On May 15, the Krupp concern reported that shielding for the hull and turret box had been manufactured and tested. The forehead of the turret box received additional sheets 30 mm thick, due to which their total thickness increased to 60 mm. The sides were reinforced with 20 mm thick screens. Later, in addition to these screens, a reinforcement was made for the frontal hull sheet, while corners appeared at the top and bottom for additional reinforcement.

Nevertheless, until the end of the French campaign, the troops did not receive a single shielding kit. Deliveries began only on June 25, when they were already, in general, not really needed. From July 1940, tanks began to be equipped with screens as standard. At the same time, the thickness of the front hull plate, turret and armor of the gun mantlet increased to 50 mm.

Another serious metamorphosis with the Pz.Kpfw.IV Ausf.D happened in August 1940. According to the decision made on June 3 of the same year, the last 68 4.Serie / B.W. and 5.Serie/B.W. were made with turrets and turret boxes 6.Serie/B.W. The last such vehicles were delivered to the troops in October 1940, after which tanks of the Pz.Kpfw.IV Ausf.E modification went into production.

The machines of this series received serial numbers 80801-81006. They can be distinguished from the latest 68 Pz.Kpfw.IV Ausf.Ds only if the vehicle's serial number is known. Additional confusion in what is happening is the fact that not all Pz.Kpfw.IV Ausf.E, not to mention Ausf.D, received screens on the frontal part of the turret box.

At the beginning of 1941, some tank units tried to do shielding on their own, but an order came from above to stop this activity. However, another modification was born, also known as the Vorpanzer. It differed in that quite massive screens were attached to the front of the tower. They were installed on tanks of the Ausf.D, E and F modifications. Apparently, the Vorpanzer were used exclusively by the Grossdeutschland (Großdeutschland) Panzer Division. It is believed that the division used them only in exercises, but there are also front-line photographs that refute such claims.

For crossings and other purposes

Orders for Pz.Kpfw.IV tanks of the 4th, 5th and 6th series were not fulfilled in full. Some of total number ordered Pz.Kpfw.IV Ausf.D went to other targets. 16 chassis produced in March-April 1940 went to the manufacture of bridge tanks Brückenleger IV b. These vehicles were included in the engineering battalions assigned to tank divisions. They were used as part of the units that fought during the May-June 1940 campaign in France.

Meanwhile, in the summer of 1940, Krupp produced 16 sets of turret boxes and turrets. Later, three bridge tanks with numbers 80685, 80686 and 80687 were converted into regular Pz.Kpfw.IV Ausf.D. According to a report for May 1941, out of 29 Pz.Kpfw.IVs produced, 13 belonged to 4.Serie/B.W. Thus, 247 vehicles of the Ausf.D modification nevertheless went to the troops as ordinary tanks. The last, 248th car with serial number 80625 was used as a test chassis.

A slightly different situation developed with the Pz.Kpfw.IV Ausf.E. Instead of the 223 tanks that were originally planned to be built, 206 vehicles were produced in one form or another, of which 200 were ordinary tanks. In January 1941, 4 chassis 6.Serie/B.W. was sent to Magirus, where they were built bridge layers Brückenleger IV c. Like the vehicles of the previous series, they went to the 39th tank engineering battalion, attached to the 3rd tank division. In this form, they participated in the battles on the Eastern Front in the summer of 1941.

The fate of the last two tanks of the 6th series, numbers 81005 and 81006, turned out to be even more interesting. On December 14, 1940, the 6th Department of the Armaments Directorate gave the go-ahead to the Krupp concern to develop a new undercarriage. Its main difference was that the diameter of the road wheels grew to 700 mm, and in order for all of them to fit, they had to be placed in a checkerboard pattern. The width of the tracks at the same time increased to 422 mm. During 1941-42, these vehicles were actively tested, and then tank 81005 ended up in the Wünsdorf training center. Also, at least one tank was converted into an ammunition carrier for the Gerät 040 ("Karl") heavy self-propelled mortar.

Finally, some of the serial tanks were converted into very specific special vehicles. In August-July 1940, 48 Pz.Kpfw.IV Ausf.Ds were converted into Tauchpanzer IV, a tank for crossing rivers along the bottom. Attachments for special sealed covers were installed on the tank, and covers were also placed on the air intakes. In addition, a special hose with a float was used, through which air was supplied to the machine. Similarly, a number of Pz.Kpfw.IV Ausf.Es produced in January-March 1940 were redone. Similar vehicles were used in June 1941 as part of the 18th Panzer Division.

Blitzkrieg support vehicle

In April 1941, production of 7.Serie/B.W., aka Pz.Kpfw.IV Ausf.F., began. This tank was created taking into account the experience of the campaigns of the first two years of the war. But it only became the main support tank for the German army in the fall of 1941. Of the 441 Pz.Kpfw.IV, which by June 22, 1941 concentrated on the border with the USSR, they were a minority. The basis was Pz.Kpfw.IV Ausf.D and Ausf.E.

By that time, the tanks of these modifications had changed somewhat. On February 14, 1941, the first German tanks arrived in Tripoli, and on the 16th, the Afrika Korps was formed. In this regard, back in early February, a “tropical” set for the ventilation system was developed.

Since March, they began to put a turret box for personal belongings on tanks. Since it was originally designed for the Afrika Korps, it was nicknamed the "Rommel box". It was not placed on all tanks. On many tanks, boxes on the turrets were not installed at all, and instead of them, an analogue was placed on the side of the hull. And in some units they developed their own "Rommel Box", which differs in shape from the regular one.

And this was only the beginning of all sorts of alterations that were introduced at the level of tank divisions, and sometimes even at the level of battalions. The body kit itself, which the Pz.Kpfw.IV received only in 1941, is a topic for a separate large material.

The Pz.Kpfw.IVs that ended up in Africa found themselves, figuratively speaking, in greenhouse conditions. In February 1941, 20 tanks were sent there, 3 of which were lost on the way, 20 more units arrived in April. The only truly dangerous enemy for them was the Matildas, which was primarily due to the thick armor of these English tanks. The 2-pounder (40-mm) guns on the British vehicles could only penetrate the shielded forehead of the Pz.Kpfw.IV at point-blank range, and such cases were rare.

Quite different conditions turned out to be on the Eastern Front. During the fighting at the end of June 1941, only 15 Pz.Kpfw.IVs were irretrievably lost. This is largely due to the fact that their opponents were T-26 and BT, who performed in a completely different weight category. The atmosphere of complete confusion in the first weeks of the Great Patriotic War also contributed. However, already in July, 109 tanks, that is, a quarter of the original number, were scrapped. In August, 68 more cars were added to them. In total, in 1941, the Germans lost 348 Pz.Kpfw.IVs on the Eastern Front, that is, more than 3/4 of their original number.

The German tank crews could quite rightly blame the 6th department of the Arms Directorate for such significant losses, which approached the issue of strengthening the armor very lightly. In fact, the shielding installed on the tanks corresponded to the experience of the September 1939 campaign. At the same time, the fact that the French already had 47-mm tank and anti-tank guns was ignored. And this was done completely in vain: even a 47-mm SA 35 tank gun with a barrel length of 32 calibers, as tests in the USSR showed, pierced 50 mm armor of German tanks at a distance of 400 meters without any problems.

Even more depressing for the Germans were the characteristics of the 47 mm Canon de 47 Mle.1937 anti-tank gun, in which the barrel length was 50 calibers. At a distance of a kilometer, she pierced armor with a thickness of 57 mm. The Germans could reasonably assume that the French were not the only ones with more powerful anti-tank artillery and tank guns than the Poles.

Ultimately, the Wehrmacht had to pay for the miscalculations of the military leadership in assessing the weapons of the enemy with tanks and their crews. While the main opponents of the Pz.Kpfw.IV were the T-26 and BT, everything was shaping up for German tankers relatively good. In the future, more and more often they had to deal with the T-34 and KV-1, armed with 76-mm guns. In addition, some of the tanks ended up with only partially thickened armor, which significantly reduced the chances of surviving even under fire from 45-mm tank and anti-tank guns.

Made a certain contribution and heavy tanks KV-2. The hit of his 152-mm projectile on a German tank turned it into a pile of scrap metal. However, penetration by other shells did not bring anything good. Cases of ammunition detonation were quite common for the Pz.Kpfw.IV. It is worth noting that German tanks were almost powerless against the T-34 and KV-1. Regular armor-piercing shells had almost no effect against new Soviet tanks, and the 7.5 cm Gr.Patr.38 Kw.K. Hitler allowed the use only in February 1942.

Already in August 1941, the captured Pz.Kpfw.IV Ausf.E from the 20th Panzer Division was delivered to the site of the Scientific Research Testing Institute armored vehicles(NIIBT Polygon) to Kubinka. The car was quite badly damaged: there were several hits in the frontal part of the hull, and the shielding in the area of ​​​​the driver's viewing device was also partially shot down. The staff of the Polygon compiled a brief description, according to which the combat weight of the tank, designated as the “Medium Tank T-IV of the 1939-40s”, was estimated at 24 tons, and the maximum speed was 50 km / h. After preliminary calculations, the following conclusions were made:

.“The armor protection of the T-IV tank is affected by artillery of all calibers.

The tank turret, inspection hatches, ball mount of the radio operator's machine gun are affected by large-caliber small arms.

Captured Pz.Kpfw.IV from the end of 1941 became a fairly frequent occurrence. Nevertheless, the NIIBT Polygon did not engage in bringing the tank captured back in the summer of 1941 into working condition or trying to get a running trophy.

This is largely due to the fact that the Soviet military did not show much interest in the tank. It seems that they considered it as an addition to the Pz.Kpfw.III, despite the fact that the combat weight and engine of the two medium tanks were similar. For approximately the same reasons, the StuG III Ausf.B was not restored to running condition. Studying the driving characteristics of the captured PzIII and Pz38(t) was considered a more important task, and spending time on secondary vehicles was considered a pointless exercise.

In September 1942, tests took place, during which captured tank was fired from various weapons. First of all, he was fired upon DShK machine gun. It turned out that the side of the DShK turret did not penetrate even from a distance of 50 meters, but at a distance of 100 meters it was possible to break through the side and rear of the hull.

Much more interesting were tests by shelling from a 45-mm cannon installed in the T-70 tank. At a distance of 50 meters, a frontal hull sheet 50 mm thick was pierced. It is worth noting that the same gun did not penetrate the captured StuG III self-propelled guns. Boards with a thickness of 40 mm (20 + 20 mm) were pierced at a distance of 400 meters.

The final verdict on the German tank was the shelling of the 76-mm F-34 cannon mounted in the T-34 medium tank. The front plate was pierced at a distance of 500 meters (inlet diameter of the through hole - 90 mm, output - 100 mm). The next shot, made from a distance of 800 meters, split the sheet into two parts. When firing from a distance of 800 meters into the side of the hull, the projectile pierced the 40-mm armor on the right side, exploded inside and exited from the left side. When firing a high-explosive projectile on the side, the side turret hatch was torn off by the first hit, the commander's turret was torn off by the second projectile, and hitting the side of the engine compartment (20 mm thick) led to a breach measuring 130 × 350 mm. It was decided not to fire from long distances - and so everything was clear.

In addition to shelling, NII-48 specialists studied the design of the hull and turret.

In July 1942, the few Ausf.D and Ausf.E tanks remaining in service were upgraded. Instead of a regular gun, they installed a long-barreled 7.5 cm KwK 40 gun. In addition, from May 1943, side screens began to be installed on the hull and turret. By that time, these machines had been withdrawn from the first line and transferred to training units, including the institutions of the NSKK (National Socialist Mechanized Corps).

Such tanks were also part of tank units stationed in France. One of them (Pz.Kpfw.IV Ausf.D, serial number 80732, released in July 1940) was captured by the British in the summer of 1944. It is now on display at the Bovington Tank Museum.

Description

Panzerkampfwagen IV (7.5 cm) Ausführung F2 or Pz.Kpfw. IV Ausf. F2 - medium tank of the armed forces of the Third Reich. Unlike previous modifications, it was armed with a long-barreled 75-mm KwK 40 gun with a barrel length of 43 calibers and improved armor protection. It became the first German tank capable of standing up to the Soviet T-34 and KV-1 tanks on an equal footing, but this only applied to weapons, in terms of armor protection it was still inferior to its rivals and could easily be destroyed by Soviet tank 76-mm guns. For this reason, the armor of the vehicle was often reinforced by the crew itself by attaching spare tracks and other improvised means.

Issue Pz.Kpfw. IV Ausf. F2 lasted from April to July 1942. During this period, 175 units were built and another 25 vehicles were converted from the F1 modification. The tank was used mainly on the Eastern Front, part of the vehicles of this modification was sent to the African Corps, where it was used to suppress the firing points and manpower of the allies, due to the shortage of armor-piercing shells. The tank played a significant role in the war, counteracting the tanks and armored vehicles of the Allies, which the rest of the German tanks, which had weaker weapons, could not cope with. After the production of the F2 modification was discontinued, the vehicle gave way to more advanced modifications of the Pz.Kpfw medium tank. IV.

Main characteristics

Armor protection and survivability

The location of the crew and modules inside the Pz.Kpfw. IV Ausf. F2

Pz.Kpfw. IV Ausf. The F2 does not have the best armor protection among similar tanks on its battle rating (BRe). The entire frontal armor of the tank has a thickness of 50 mm, except for the armor section under the driver's slot, which has a thickness of 20 mm, but is located at an angle of inclination of 73 degrees, which gives the reduced armor thickness the same 50 mm. In addition, having studied the modification "Applied Armor", the frontal armor is reinforced with additional tracks 15 mm thick. The side and rear armor of the turret and hull is 30 mm and is easily hit even by heavy machine guns. The tight layout of the crew and modules negatively affects the survivability of the tank. The downside is the high commander's cupola, which can protrude from behind cover, even if the tank is completely hidden from the eyes of opponents.

Mobility

Pz.Kpfw. IV Ausf. F2 has high speed and mobility. The maximum speed of the car is 48 km / h, it is gained quickly and is almost not lost from small obstacles. The rear speed is 8 km / h and it is quite enough to roll back after a shot or to pass backwards to drive behind cover. The maneuverability of the car is good both from a standstill and while driving. From a standstill, the tank turns around briskly, even better and faster on the move, but noticeably loses speed. Patency Pz.Kpfw. IV Ausf. F2 high.

Armament

main gun

The most important advantage of the Pz.Kpfw. IV Ausf. F2 is its long-barreled 75 mm KwK40 L43 gun with 87 rounds of ammunition. The gun has simply amazing armor penetration. Due to the length of the barrel, unlike previous modifications with short-barreled guns, the KwK40 L43 has good projectile ballistics. In terms of armored action, Pz.Kpfw. IV Ausf. F2 is inferior to T-34 and KV-1 shells, but it is quite enough to destroy most of the enemy with one accurate hit. Gun reload is fast. Elevation angles range from -10 to +20 degrees, which allows you to fire from behind hills and obstacles hiding the hull behind them. The turret rotates at an average speed, so sometimes you will have to turn your body towards an enemy that suddenly appears.

Five types of shells are available for the tank:

• PzGr 39- an armor-piercing projectile with an armor-piercing tip and a ballistic cap. It has excellent armor penetration and good armor action. Recommended as the main projectile for this tank.

• Hl.Gr 38B- cumulative projectile. It has less armor penetration than the PzGr 39, but retains it at all distances. Recommended for shooting at enemies at very long distances.

• PzGr 40- armor-piercing sub-caliber projectile. It has the highest armor penetration, but much less armor penetration than the PzGr 39, and also significantly loses its armor penetration at long distances. In addition, the projectile is not very effective against opponents with sloped armor. Recommended for use at close range against heavily armored opponents.

• Spgr. 34- high-explosive fragmentation projectile. It has the lowest armor penetration of all the presented shells. Can be effective against non-armored vehicles, such as anti-aircraft self-propelled units(ZSU) based on trucks.

• K.Gr.Rot Nb.- smoke projectile. It does not have armor penetration, it can cause damage only by hitting directly on the enemy crew. Temporarily releases a large cloud of smoke through which it will be impossible for the enemy to see the actions and movement of the player.

Machine gun armament

Pz.Kpfw. IV Ausf. The F2 is armed with a 7.92mm MG34 machine gun with 3,000 rounds of ammunition coaxial with a 75mm gun. Can incapacitate the crew on vehicles that do not have armor, for example, ZSU based on trucks.

Use in combat

To protect the vulnerable hull of the Pz.Kpfw. IV Ausf. F2, it is better to choose such positions that would completely cover the body from enemy shells

Playing on Pz.Kpfw. IV Ausf. F2, you should always be aware of its weak armor and high vulnerability. Thanks to its high speed, the Pz.Kpfw. IV can be one of the first to arrive at the capture point, but if there are no shelters on the point, then you can be an easy prey for enemy tanks. The same applies to the attack, you need to avoid open areas of the terrain where the vehicle will be easily destroyed and move only from cover to cover, destroying enemy tanks because of them. Well suited to the car and the role of a sniper. A good car for flanking detours, fast speed will allow you to easily go into the flank or rear of the enemy, and the effect of surprise and good tool will cause significant damage to the enemy team.

Advantages and disadvantages

The armor does not have rational angles, so turn the hull a little, but not too much, so as not to expose even weaker sides, good dynamics and mobility will allow you to take important positions quickly, and the UVN will shoot in most situations.

Advantages:

• Excellent armor penetration
• High flatness
• Good armor action of shells
• Remarkable speed and maneuverability
• Good cross
• Fast reload

Flaws:

• Weak booking
• Tight layout

History reference

In January 1934, the German War Department's Ordnance Department held a design competition for a new medium tank. Krupp, MAN, Daimler-Benz and Rheinmetall took part in the competition. The competition was won by the Krupp project, under the designation VK 2001(K). The new tank was conceived by the German command as a support tank for attacking forces, its main task was to suppress enemy firing points, mainly such as machine gun nests and anti-tank gun crews, as well as to fight enemy light armored vehicles. In terms of its design and layout, the tank was made in the classic German style - with the location of the control and transmission compartment in the front, the fighting compartment in the middle and the engine compartment in the rear of the hull. The tank was armed with a short-barreled 75-mm gun. Initially, observing the secrecy from the prohibitions of the Treaty of Versailles, the new vehicle was designated as Bataillonsführerwagen or B.W., which means "battalion commander's vehicle", later the tank received its final designation - Pz.Kpfw. IV (Panzerkampfwagen IV) or Sd.Kfz. 161, in Soviet and domestic sources T-4 or T-IV.

The first modification of the tank Pz.Kpfw. IV Ausf. A

The first pre-production samples of the Pz.Kpfw. IV, designated Ausf.A, they were produced in late 1936/early 1937. At the time of the outbreak of hostilities by Germany, on September 1, 1939, there were only 211 Pz.Kpfw tanks in the Wehrmacht tank fleet. IV of all modifications. Although these vehicles did not meet worthy rivals in the Polish campaign, the small-caliber anti-tank artillery Polish troops inflicted serious losses on German tanks. For this reason, urgently, measures were taken to strengthen the armor protection of tanks. The French campaign, where German tank forces clashed with French and British armored vehicles, only confirmed that the Pz.Kpfw. IV still did not have sufficient armor, in addition, it also showed that short-barreled 75-mm guns were powerless against heavy British tanks"Matilda". But the final cross on the production of Pz.Kpfw. IV with short-barreled guns was delivered by the campaign against the USSR, which began on June 22, 1941. Already in July of the same year, faced with heavy tanks KV-1 and medium T-34, the Germans realized that short guns could not do anything to new Soviet tanks, even with a point-blank shot.

Pz.Kpfw. IV Ausf. F1 with a short gun

For this reason, in the late autumn of 1941, a hasty development of a new, long-barreled 75-mm tank gun began, which could successfully withstand the Soviet T-34 and KV-1. The idea of ​​installing a 50 mm gun with a barrel length of 42 calibers was previously put forward, but the experience of the war on the Eastern Front showed that the Soviet 76 mm guns were superior to the German 50 mm in all respects. To install a new gun, a modification of the Pz.Kpfw. IV Ausf. F, which was produced from April 1941 and was the result of an analysis of the course of hostilities in Poland and France. Unlike all previous modifications, the Ausf. F armor thickness of the forehead of the turret and hull increased to 50 mm, the sides to 30 mm, the frontal hull plate became straight, single-leaf hatches on the sides of the turret were replaced with double-leaf ones. Due to the increased mass of the tank and the specific pressure on the ground, the vehicle received new tracks 400 mm wide, instead of 360 mm, as on all previous modifications.

With the installation of a 75-mm long-barreled gun KwK 40 with a barrel length of 43 calibers on the tank, the designation of the tank Pz.Kpfw. IV Ausf. F, at the end, the numbers 1 and 2 were added, where the number 1 - meant that the car was with a short-barreled gun, and 2 - with a long-barreled gun. The combat weight of the tank reached 23.6 tons. Production Pz.Kpfw. IV Ausf. F2 began in March 1942 and ended in July of that year, giving way to other, more advanced modifications. During this period, 175 Ausf vehicles were produced. F2 and 25 more were converted from F1. With the advent of long-barreled guns, Pz.Kpfw. IV got the opportunity to compete on equal terms with Soviet heavy and medium tanks, but this only concerned weapons, in terms of armor protection the vehicle was inferior to the Soviet T-34 and, even more so, the KV-1. In addition, the increased weight of the vehicle reduced its speed and maneuverability, and the installation of a long-barreled gun increased the weight on the front of the hull, which led to rapid wear of the front rollers and led to a strong buildup of the tank during a sharp stop and after a shot.

PzKpfw IV ausf F2 review by CrewGTW

No one at the Krupp factory 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 in the battle. With a final total of 9000 units, it became the most bulk tank, ever produced in Germany, whose production volumes, despite the lack of materials, grew to the most last days World War II in Europe.

Wehrmacht work horse

Despite the fact that there were combat vehicles more modern than the German T-4 tank - "Tiger", "Panther" and "King Tiger", it not only made up the majority of the Wehrmacht's weapons, 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 a wider array of weapons than the Panzer III. From Model A to F1, the early modifications using the short 75mm barrel were gradually replaced by the "long" ones, F2 to H, with a very effective high-velocity cannon inherited from the Pak 40 that could deal 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

Initially, it was assumed that the German T-4 tank, the technical characteristics of which were determined in 1934 by the Waffenamt, would serve as an “escort vehicle to hide his true role, forbidden by the terms of the Treaty of Versailles.

Heinz Guderian took part in the development of the concept. This new model was supposed to be an infantry support tank and placed in the rear. It was planned that at the battalion level one such vehicle should be for every three Panzer IIIs. Unlike the T-3, which was equipped with a variant of the standard 37 mm Pak 36 gun with good anti-tank performance, 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 of the combat vehicle was 24 tons. MAN, Krupp and Rheinmetall-Borsig produced three prototypes and Krupp received the main contract. The suspension was brand new at first, with six alternating wheels. Later, the army demanded the installation of rod springs, which provided better vertical deflection. Compared to the previous system, this made for a smoother ride, but the need for a new tank stopped further development. Krupp reverted to a more traditional system with four twin wheeled bogies and leaf springs for ease of maintenance. A crew of five was planned - three were in the tower (commander, loader and gunner), and the driver with a radio operator was in the hull. The fighting compartment was relatively spacious, with improved soundproofing in the rear engine compartment. The German T-4 tank inside (photos in the material illustrate this) was equipped with an on-board communication system and a 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 turning. As a result, ammunition boxes were located on the right.

The prototype, designed and built in 1936 at the Krupp AG factory in Magdeburg, was designated Versuchskraftfahrzeug 622 by the Army Ordnance Department. Nevertheless, it quickly became known as Pz.Kpfw.IV (Sd.Kfz. 161) in the new pre-war nomenclature.

The tank had a Maybach HL108TR gasoline engine with an HP 250 power. with., and the SGR 75 box with five forward and one reverse gears. The maximum speed on tests on a flat surface was 31 km / h.

75 mm gun - low speed Kampfwagenkanone (KwK) 37 L/24. This gun was intended for firing at concrete fortifications. Nevertheless, some anti-tank capability was provided by the armor-piercing Panzergranate projectile, whose speed reached 440 m/s. It could penetrate 43 mm steel sheet at a distance of 700 m. Two MG-34 machine guns completed the armament, one coaxial and the other in 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 did not exceed 20 mm. Although it was hardened steel, such protection could only withstand light firearms, light artillery and fragments of grenade launchers.

Early "short" pre-series

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 dome, a new Maybach HL 120TR engine developing 300 hp. s., and also new transmission SSG75.

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

After the release of 42 vehicles, production switched to the German T-4 C tank. The thickness of the armor on the turret increased to 30 mm. The total weight was 18.15 tons. After the 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 brought out. The thickness of the side armor has increased to 20 mm. A total of 243 machines of this model were manufactured, the last of which was at the beginning of 1940. Modification D was the last pre-production, 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 speak of the lack of penetrating power of the 37 mm Panzer III gun, its replacement was not possible. Looking for a solution to test one Panzer IV Ausf. D, a modification of the medium-velocity 50 mm Pak 38 gun 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 turned out that the thickness of the armor was insufficient, and the penetrating power of the gun was weak. In Ausf. E retained the KwK 37L/24 short 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 the Ausf. F, its production reached 280 units.

Latest "short" model

Another modification significantly changed the German T-4 tank. Characteristics early model F, renamed F1 when the next one appeared, have changed due to the replacement of the front patch plate with a 50 mm plate and the increase in the thickness of the sides of the hull and turret to 30 mm. The total weight of the tank grew to over 22 tons, which prompted other changes such as an increase in track width from 380 mm to 400 mm to reduce ground pressure from appropriate replacement two tension and driving wheels. The F1 was produced at 464 before being replaced in March 1942.

The first "long"

Even with the armor-piercing Panzergranate projectile, the Panzer IV's low-velocity cannon was no match for heavily armored tanks. In the context of the upcoming campaign in the USSR, a decision was to be made on a major upgrade of the T-3 tank. The now available Pak 38L/60 gun, the effectiveness of which was 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, the manufacture of the 50 mm gun, also used in the Panzer III, was discontinued in favor of a new, more powerful Rheinmetall model based on the 75 mm Pak 40L / 46 gun. This led to the KwK 40L/43, a relatively long caliber equipped to reduce recoil. The muzzle 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 were manufactured. In June, the German T-4 F2 tank was renamed to T-4 G, but for the Waffenamt both types were designated as Sd.Kfz.161/1. In some documents, the model is referred to as F2/G.

transitional model

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

The German T-4 tank has undergone significant changes inside. Tower viewing slots were 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.

In later versions in the spring of 1943, side armor appeared on the hull and turret, as well as smoke grenade launchers. But most importantly, a new, more powerful KwK 40L / 48 gun appeared. After 1275 standard and 412 improved tanks, production shifted towards the Ausf.H.

Main version

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

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

Latest simplified model

The last tank, the German T-4J, was assembled at the Nibelungwerke in St. Valentin, Austria, as Vomag and Krupp were now on different missions, and were subjected to simplifications geared towards more mass production and rarely supported by crews. For example, the turret electric drive was removed, aiming was carried out 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 observation window, slits and anti-aircraft machine in favor of mounting a smoke grenade launcher. "Zimmerit" was no longer used, as well as anti-cumulative "skirts" Schürzen, replaced by cheaper mesh panels. The engine radiator housing has also been simplified. The drive has lost one return roller. There were two silencers with flame arresters, 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 casualties, deliveries were in jeopardy due to constant Allied bombing, and a total of only 2,970 out of 5,000 planned tanks were completed by the end of March 1945.

Modifications

German tank T-4: performance characteristics

It must be said that a large number of Panzer IV tanks that survived after 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 the 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 condition.
