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 was mounted here, in which three crew members were accommodated and weapons were installed.

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;
- N-K modifications, 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 of the 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 supporters of tanks believed that the appearance of armored vehicles would be made with tactical point view of the impossible trench warfare in the fighting style of 1914-1917. 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 a 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 mass production.
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 massive tank of panzer divisions 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 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 projects for a 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 Directorate, 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 chassis 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 plant 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 captured tank PzKpfw IV Ausf.E, 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 at Woolwich on the study of armor protection of a German tank notes that "armor is 10% better than similar machined English, and in some respects even better than 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 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. 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. The recommended engine speed under normal operating conditions is 2600 rpm, but in hot climates (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 maneuverability of tanks in 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. Minimum temperature engine, at which it began to work normally was t=50 gr.C with a shaft rotation of 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 the engine of one tank was started and warmed up to normal temperature, warm water from it was pumped into the cooling system of the next tank, and cold water was supplied to the already running engine - the refrigerants of the working and idle engines were exchanged. 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.

"Panzerkampfwagen IV" ("PzKpfw IV", also "Pz. IV"; in the USSR it was also known as "T‑IV") - medium tank armored troops of the Wehrmacht during the Second World War. There is a version that the Pz IV was originally classified by the German side as a heavy tank, but it has not been documented.

The most massive tank of the Wehrmacht: 8,686 vehicles were produced; serially produced from 1937 to 1945 in several modifications. The ever-increasing armament and armor of the tank in most cases allowed the PzKpfw IV to effectively resist tanks of a similar class. The French tanker Pierre Danois wrote about the PzKpfw IV (in modification, at that time, still with a short-barreled 75-mm gun): “This medium tank was superior to our B1 and B1 bis in all respects, including weapons and, to some extent, armor ".

History of creation

Under the terms of the Treaty of Versailles, defeated in the First World War, Germany was forbidden to have armored troops, with the exception of a small number of armored vehicles for the needs of the police. But despite this, since 1925, the Reichswehr Armaments Office has been secretly working on the creation of tanks. Until the early 1930s, these developments did not go beyond the construction of prototypes, both because of the insufficient performance of the latter, and because of the weakness of the German industry of that period. However, by the middle of 1933, German designers managed to create their first production tank- Pz.Kpfw.I and during 1933-1934 start its mass production. The Pz.Kpfw.I, with its machine gun armament and crew of two, was seen as only a transitional model on the way to building more advanced tanks. The development of two of them began back in 1933 - a more powerful "transitional" tank, the future Pz.Kpfw.II and a full-fledged battle tank, the future Pz.Kpfw.III, armed with a 37-mm cannon, designed mainly to fight other armored vehicles.

Due to the initial armament limitations of the Pz.Kpfw.III, it was decided to supplement it with a fire support tank, with a longer-range cannon with a powerful fragmentation projectile capable of hitting anti-tank defenses beyond the reach of other tanks. In January 1934, the Armaments Department organized a project competition for the creation of a machine of this class, whose mass would not exceed 24 tons. Since work on armored vehicles in Germany at that time was still carried out in secret, the new project, like the rest, was given the code name “support vehicle” (German: Begleitwagen, usually abbreviated to B.W .; incorrect names are given in a number of sources of German. Bataillonwagen and German Bataillonfuehrerwagen). From the very beginning, the firms Rheinmetall and Krupp took up the development of projects for the competition, later they were joined by Daimler-Benz and M.A.N. Over the next 18 months, all firms presented their developments, and the Rheinmetall project under the designation VK 2001 (Rh) was even made in metal in the form of a prototype in 1934-1935.

Tank Pz.Kpfw. IV Ausf. J (Armoured Vehicles Museum - Latrun, Israel)

All presented projects had a chassis with a staggered arrangement of large diameter road wheels and no carrier rollers, with the exception of the same VK 2001 (Rh), which, on the whole, inherited the chassis with small diameter road wheels interlocked in pairs and side screens from the experimental heavy tank Nb.Fz. As a result, the Krupp project - VK 2001 (K) was recognized as the best of them, but the Arms Administration did not satisfy its spring suspension, which they demanded to be replaced with a more advanced torsion bar. However, Krupp insisted on the use of a running gear with medium-diameter rollers interlocked in pairs on a spring suspension, borrowed from the rejected Pz.Kpfw.III prototype of its own design. In order to avoid the inevitable delays in the processing of the project for a torsion bar suspension with the start of production of a tank badly needed by the army, the Ordnance Department was forced to agree to the Krupp proposal. After the subsequent refinement of the project, Krupp received an order for the production of a pre-production batch of a new tank, which by that time had received the designation "armored vehicle with a 75-mm gun" (German: 7.5 cm Geschütz-Panzerwagen) or, according to the end-to-end designation system adopted at that time, "experimental model 618" (German: Versuchskraftfahrzeug 618 or Vs.Kfz.618). From April 1936, the tank acquired its final designation - Panzerkampfwagen IV or Pz.Kpfw.IV. In addition, he was assigned the index Vs.Kfz.222, previously owned by Pz.Kpfw.II.

Mass production

Panzerkampfwagen IV Ausf.A - Ausf.F1

The first few Pz.Kpfw.IV "zero" series were manufactured in 1936-1937 at the Krupp factory in Essen. The serial production of the first series, 1.Serie / B.W., was launched in October 1937 at the Krupp-Gruson plant in Magdeburg. In total, until March 1938, 35 tanks of this modification were produced, designated as Panzerkampfwagen IV Ausführung A (Ausf.A - “model A”). According to the unified designation system of German armored vehicles, the tank received the index Sd.Kfz.161. The Ausf.A tanks were in many ways still pre-production vehicles and carried bulletproof armor that did not exceed 15-20 mm and weakly protected observation devices, especially in the commander's cupola. At the same time, the main design features of the Pz.Kpfw.IV had already been determined on the Ausf.A, and although the tank was subsequently upgraded many times, the changes mainly boiled down to the installation of more powerful armor and weapons, or to an unprincipled alteration of individual units.

Immediately after the end of production of the first series, Krupp began production of an improved 2.Serie / B.W. or Ausf.B. The most noticeable outward difference of the tanks of this modification was a straight upper frontal plate, without a prominent driver's cabin and with the elimination of the course machine gun, which was replaced by a viewing device and a hatch for firing personal weapons. The design of viewing devices was also improved, primarily the commander's cupola, which received armored shutters, and the driver's viewing device. According to other sources, the new commander's cupola was already introduced during production, so some of the Ausf.B tanks carried the old-style commander's cupola. Minor changes also affected the landing hatches and various hatches. Frontal armor on the new modification was brought up to 30 mm. The tank also received a more powerful engine and a new 6-speed gearbox, which made it possible to significantly increase its maximum speed, and its cruising range also increased. At the same time, the ammunition load of the Ausf.B was reduced to 80 rounds for the gun and 2,700 machine gun rounds, instead of 120 and 3,000 rounds for the Ausf.A, respectively. Krupp was given an order for the production of 45 Ausf.B tanks, but due to a shortage of components, only 42 vehicles of this modification were actually produced from April to September 1938.

The first relatively massive modification was 3.Serie/B.W. or Ausf.C. Compared to the Ausf.B, the changes in it were insignificant - externally, both modifications are distinguishable only by the presence of an armored casing for the barrel of a coaxial machine gun. The rest of the changes came down to replacing the HL 120TR engine with an HL 120TRM of the same power, as well as the beginning of installing a fender under the gun barrel on part of the tanks to bend the antenna located on the hull when the turret turns. In total, 300 tanks of this modification were ordered, but already in March 1938 the order was reduced to 140 units, as a result of which, according to various sources, 140 or 134 tanks were produced from September 1938 to August 1939, while 6 chassis were transferred for conversion into bridgelayers.

Museum Pz.Kpfw.IV Ausf.D with additional armor

Machines of the next modification, Ausf.D, were produced in two series - 4.Serie / B.W. and 5.Serie/B.W. most notable external change there was a return to the broken upper frontal plate of the hull and the course machine gun, which received enhanced protection. The inner mantlet of the gun, which proved vulnerable to lead spatter from bullet hits, was replaced with an outer one. The thickness of the side and rear armor of the hull and turret was increased to 20 mm. In January 1938, Krupp received an order for the production of 200 4.Serie / B.W. and 48 5.Serie/B.W., but during production, from October 1939 to May 1941, only 229 of them were completed as tanks, while the remaining 19 were allocated for the construction of specialized variants. Some of the late production Ausf.D tanks were produced in a "tropical" version (German tropen or Tp.), with additional ventilation holes in the engine compartment. A number of sources speak of armor reinforcement carried out in 1940-1941 in parts or during repairs, which was carried out by bolting additional 20-mm sheets to the upper side and frontal plates of the tank. According to other sources, later production vehicles were regularly equipped with additional 20 mm side and 30 mm frontal armor plates of the Ausf.E type. Several Ausf.Ds were re-armed with KwK 40 L/48 long guns in 1943, but these converted tanks were only used as training tanks.

The appearance of a new modification, 6.Serie/B.W. or Ausf.E, was caused primarily by the lack of armor protection of vehicles early series, demonstrated during Polish campaign. On Ausf.E, the thickness of the lower frontal plate was increased to 50mm, in addition, it became standard to install additional 30mm plates above the upper frontal and 20mm above the side plates, although on a small part of the tanks of early production, additional 30mm plates were not were established. The armor protection of the tower, however, remained the same - 30 mm for the frontal plate, 20 mm for the side and aft plates and 35 mm for the gun mantlet. A new commander's cupola was introduced, with a vertical armor thickness of 50 to 95 mm. The inclination of the aft wall of the turret was also reduced, now made of a single sheet, without the "influx" for the turret, and on late production vehicles, an unarmored equipment box was attached to the stern of the turret. In addition, the Ausf.E tanks featured a number of less noticeable changes - a new driver's viewing device, simplified drive and steering wheels, an improved design of various hatches and inspection hatches, and the introduction of a turret fan. The order for the sixth series of Pz.Kpfw.IVs amounted to 225 units and was completed in full between September 1940 and April 1941, in parallel with the production of Ausf.D tanks.

Pz.Kpfw.IV Ausf.F. Finland, 1941.

Shielding with additional armor (on average by 10-12 mm), used on previous modifications, was irrational and was considered only as a temporary solution, which was the reason for the appearance of the next modification, 7.Serie/B.W. or Ausf.F. Instead of using hinged armor, the thickness of the frontal top plate of the hull, the frontal plate of the turret and the mantlet of the gun was increased to 50 mm, and the thickness of the sides of the hull and the sides and rear of the turret was increased to 30 mm. The broken upper frontal plate of the hull was again replaced by a straight one, but this time with the preservation of the course machine gun, and the side hatches of the turret received double doors. Due to the fact that the mass of the tank increased by 22.5% compared to the Ausf.A after the changes made, wider tracks were introduced to reduce ground pressure. Other, less noticeable changes included the introduction of ventilation air intakes in the middle frontal plate to cool the brakes, a different arrangement of silencers and slightly modified viewing devices due to the thickening of the armor, and the installation of a course machine gun. On the Ausf.F modification, other firms, in addition to Krupp, joined the production of Pz.Kpfw.IV for the first time. The latter received the first order for 500 machines of the seventh series, later orders for 100 and 25 units were received by Vomag and Nibelungenwerke. Of this number, from April 1941 to March 1942, before switching production to the Ausf.F2 modification, 462 Ausf.F tanks were produced, 25 of which were converted to Ausf.F2 at the factory.

Panzerkampfwagen IV Ausf.F2 - Ausf.J

Although the main purpose of the 75 mm Pz.Kpfw.IV cannon was to destroy unarmored or lightly armored targets, the presence of an armor-piercing projectile in its ammunition load allowed the tank to successfully fight armored vehicles protected by bulletproof or light anti-ballistic armor. But against tanks with powerful anti-cannon armor, such as the British Matilda or the Soviet KV and T-34, it proved to be completely ineffective. Back in 1940 - early 1941, the successful combat use of the Matilda intensified work on re-equipping the Pz.Kpfw.IV with a gun with better anti-tank capabilities. On February 19, 1941, on the personal order of A. Hitler, work began on arming the tank with a 50-mm Kw.K.38 L / 42 cannon, which was also installed on the Pz.Kpfw.III, and further work to strengthen the armament of the Pz.Kpfw. IV also advanced under his control. In April, one Pz.Kpfw.IV Ausf.D was re-armed with the newest, more powerful 50 mm Kw.K.39 L/60 gun for demonstration to Hitler on his birthday, April 20th. It was even planned to produce a series of 80 tanks with such weapons from August 1941, but by that time the interest of the Ordnance Department (Heereswaffenamt) had shifted to a 75-mm long-barreled gun and these plans were abandoned.

Since the Kw.K.39 had already been approved as a weapon for the Pz.Kpfw.III, it was decided to choose an even more powerful gun for the Pz.Kpfw.IV, which could not be installed on the Pz.Kpfw.III with its smaller turret ring diameter . Since March 1941, Krupp, as an alternative to the 50 mm cannon, has been considering a new 75 mm cannon with a barrel length of 40 calibers, intended to rearm StuG.III assault guns. At a distance of 400 meters, it pierced 70 mm armor at a meeting angle of 60 °, but since the Ordnance Department demanded that the gun barrel did not protrude beyond the dimensions of the tank hull, its length was reduced to 33 calibers, which led to a decrease in armor penetration to 59 mm under the same conditions. It was also planned to develop a sub-caliber armor-piercing projectile with a detachable pallet, penetrating 86-mm armor under the same conditions. Work on re-equipping the Pz.Kpfw.IV with the new gun was going well, and in December 1941 the first prototype was built with a 7.5 cm Kw.K. L/34.5.

Tank Pz.Kpfw.IV Ausf.F2. France, July 1942.

In the meantime, the invasion of the USSR began, during which German troops encountered T-34 and KV tanks, which were slightly vulnerable to the main tank and anti-tank guns of the Wehrmacht and at the same time carried a 76-mm cannon that pierced the frontal armor of German tanks, which were then practically in service with the Panzerwaffe. at any real combat distances. The Special Tank Commission, sent to the front in November 1941 to study this issue, recommended the re-equipment of German tanks with such a weapon that would allow them to hit soviet cars from great distances, remaining outside the radius of the effective fire of the latter. On November 18, 1941, the development of a tank gun was initiated, similar in its capabilities to the new 75-mm Pak 40 anti-tank gun. Such a gun, originally designated Kw.K.44, was developed jointly by Krupp and Rheinmetall. The trunk passed to him from anti-tank gun unchanged, but since the shots of the latter were too long for use in a tank, a shorter and thicker cartridge case was developed for the tank gun, which led to a reworking of the breech of the gun and a reduction in the overall length of the barrel to 43 calibers. Kw.K.44 also received a single-chamber muzzle brake of a spherical shape, different from the anti-tank gun. In this form, the gun was adopted as the 7.5 cm Kw.K.40 L/43.

The Pz.Kpfw.IVs with the new gun were originally designated as "refitted" (German 7.Serie/B.W.-Umbau or Ausf.F-Umbau), but soon received the designation Ausf.F2, while the Ausf.F vehicles with the old guns were called Ausf.F1 to avoid confusion. The designation of the tank according to a single system changed to Sd.Kfz.161/1. With the exception of a different gun and related minor changes, such as the installation of a new sight, new shot stowage and slightly modified gun recoil armor, the early production Ausf.F2s were identical to the Ausf.F1 tanks. After a month-long break due to the transition to a new modification, the production of Ausf.F2 began in March 1942 and continued until July of the same year. A total of 175 tanks of this variant were produced and another 25 converted from the Ausf.F1.

Tank Pz.Kpfw. IV Ausf. G (tail number 727) of the 1st Panzergrenadier Division "Leibstandarte SS Adolf Hitler". The vehicle was shot down by artillerymen of the 4th battery of the 595th anti-tank artillery regiment in the area of ​​st. Sumy in Kharkov, on the night of March 11-12, 1943. On the frontal armor plate, almost in the center, two inlets from 76-mm shells are visible.

The appearance of the next modification Pz.Kpfw.IV was not initially caused by any changes in the design of the tank. In June - July 1942, by orders of the Ordnance Department, the designation Pz.Kpfw.IV with long-barreled guns was changed to 8.Serie / B.W. or Ausf.G, and in October the Ausf.F2 designation was finally abolished for previously produced tanks of this modification. The first tanks produced as the Ausf.G were thus identical to their predecessors, but more and more changes were made to the design of the tank during the course of further production. Ausf.G of early releases still carried the index Sd.Kfz.161/1 according to the end-to-end notation, which was replaced by Sd.Kfz.161/2 on later releases. The first changes, made already in the summer of 1942, included a new two-chamber pear-shaped muzzle brake, the elimination of viewing devices in the front side plates of the turret and the observation hatch for the loader in its frontal plate, the transfer of smoke grenade launchers from the rear of the hull to the sides of the turret, and a system to facilitate launching in winter conditions .

Since the 50 mm frontal armor of the Pz.Kpfw.IV was still insufficient, not providing adequate protection against 57 mm and 76 mm guns, it was again reinforced, by welding or, on later production vehicles, by bolting additional 30 mm mm plates above the upper and lower end plates of the hull. The thickness of the frontal plate of the turret and gun mantlet, however, was still 50 mm and did not increase in the process of further modernization of the tank. The introduction of additional armor began on the Ausf.F2, when 8 tanks with increased armor thickness were produced in May 1942, but progress was slow. By November, only about half of the vehicles were produced with enhanced armor, and only from January 1943 did it become the standard for all new tanks. Another significant change introduced to the Ausf.G in the spring of 1943 was the replacement of the Kw.K.40 L/43 cannon with the Kw.K.40 L/48 gun with a 48-caliber barrel, which had slightly better armor penetration. Production of the Ausf.G continued until June 1943, with a total of 1,687 tanks of this modification produced. Of this number, about 700 tanks received enhanced armor and 412 received the Kw.K.40 L/48 cannon.

The next modification, Ausf.H, became the most massive. The first tanks under this designation, which rolled off the production line in April 1943, differed from the last Ausf.G only in the thickening of the front turret roof sheet up to 16 mm and the rear up to 25 mm, as well as reinforced final drives with cast drive wheels, but the first 30 tanks Ausf.H, due to delays in the supply of new components, received only a thickened roof. Since the summer of the same year, instead of an additional 30 mm hull armor, solid-rolled 80 mm plates were introduced to simplify production. In addition, hinged anti-cumulative screens made of 5 mm sheets were introduced, which were installed on most Ausf.H. In this regard, as unnecessary, viewing devices in the sides of the hull and turret were eliminated. Since September, the tanks have been coated with vertical armor with zimmerite to protect against magnetic mines.

Late production Ausf.H tanks received a turret mount for the MG-42 machine gun at the commander's cupola hatch, as well as a vertical stern plate instead of the inclined one that was on all previous tank modifications. In the course of production, various changes were also introduced to reduce the cost and simplify production, such as the introduction of non-rubbered support rollers and the elimination of the driver's periscope viewing device. Since December 1943, the front plates of the hull began to be connected to the side connection "into a spike", to increase resistance to projectile hits. Production of the Ausf.H continued until July 1944. Data on the number of produced tanks of this modification, given in various sources, vary somewhat, from 3935 chassis, of which 3774 were completed as tanks, to 3960 chassis and 3839 tanks.

Destroyed on the Eastern Front, the German medium tank Pz.Kpfw. IV lying upside down on the side of the road. Part of the caterpillar in contact with the ground is missing, in the same place there are no rollers with a fragment of the lower part of the hull, the bottom sheet is torn off, the second caterpillar is torn off. The upper part of the machine, as far as one can judge, does not have such fatal damage. A typical picture during a land mine explosion.

The appearance of the Ausf.J modification on the assembly lines since June 1944 was associated with the desire to reduce the cost and simplify the production of the tank as much as possible in the face of the deteriorating strategic position of Germany. The only but significant change that distinguished the first Ausf.J from the latest Ausf.H was the elimination of the electric turret traverse and the associated auxiliary carburetor engine with a generator. Soon after the launch of the new modification, the pistol ports in the stern and sides of the turret were eliminated, which were useless because of the screens, and the design of other hatches was also simplified. Since July, on the site of the liquidated auxiliary engine began to install an additional fuel tank with a capacity of 200 liters, but the fight against its leakage dragged on until September 1944. In addition, the 12-mm roof of the hull began to be reinforced by welding additional 16-mm sheets. All subsequent changes were aimed at further simplifying the design, the most notable among them being the abandonment of the zimmerite coating in September and the reduction of the number of carrier rollers to three per side in December 1944. The production of Ausf.J modification tanks continued almost until the very end of the war, until March 1945, but the slowdown in production due to the weakening of the German industry and difficulties in the supply of raw materials led to the fact that only 1758 tanks of this modification were produced.

Production volumes of the T-4 tank

Design

The Pz.Kpfw.IV had a layout with a combined transmission compartment and control compartment in the front, the engine compartment in the aft, and the fighting compartment in the middle part of the vehicle. The crew of the tank consisted of five people: a driver and gunner-radio operator, located in the control compartment, and a gunner, loader and tank commander, who were in a triple tower.

Armored corps and turret

The turret of the PzKpfw IV tank made it possible to upgrade the tank gun. Inside the tower were the commander, gunner and loader. The commander's seat was directly under the commander's turret, the gunner was located to the left of the cannon breech, the loader was to the right. Additional protection was provided by anti-cumulative screens, which were also installed on the sides. The commander's cupola at the rear of the turret gave the tank good visibility. The tower had an electric turn drive.

Means of observation and communication

The tank commander in non-combat conditions, as a rule, conducted observation, standing in the hatch of the commander's cupola. In battle, to view the area, he had five wide viewing slots around the perimeter of the commander's cupola, which gave him an all-round view. The viewing slots of the commander, like those of all other crew members, were equipped with a protective triplex glass block on the inside. On the Pz.Kpfw.IV Ausf.A, the viewing slots did not have any additional cover, but on the Ausf.B, the slots were equipped with sliding armor shutters; in this form, the commander's viewing devices remained unchanged on all subsequent modifications. In addition, on tanks of early modifications in the commander's cupola there was a mechanical device for determining the heading angle of the target, with the help of which the commander could carry out accurate target designation to the gunner who had a similar device. However, due to excessive complexity, this system was eliminated starting with the Ausf.F2 modification. Viewing devices for the gunner and loader on the Ausf.A - Ausf.F consisted of, for each of them: a viewing hatch with an armored cover without viewing slots, in the frontal plate of the tower on the sides of the gun mantlet; inspection hatch with a slot in the front side plates and a viewing slot in the side hatch cover of the tower. Starting with the Ausf.G, as well as on parts of the late production Ausf.F2, viewing devices in the front side plates and the loader's viewing hatch in the frontal plate were eliminated. On the part of the tanks of modifications Ausf.H and Ausf.J, in connection with the installation of anti-cumulative screens, viewing devices in the sides of the tower were completely eliminated.

The main means of observation for the driver of the Pz.Kpfw.IV was a wide viewing slot in the frontal plate of the hull. From the inside, the slit was protected by a triplex glass block, from the outside, on the Ausf.A it could be closed with a simple folding armored flap, on the Ausf.B and subsequent modifications with a replaced Sehklappe 30 or 50 sliding flap, also used on the Pz.Kpfw.III. A periscopic binocular viewing device K.F.F.1 was located above the viewing slot on Ausf.A, but it was eliminated on Ausf.B - Ausf.D. On Ausf.E - Ausf.G, the viewing device appeared already in the form of an improved K.F.F.2, but starting with Ausf.H, it was again abandoned. The device was brought out through two holes in the frontal plate of the hull and, if it was not needed, was moved to the right. The gunner-radio operator on most modifications did not have any means of viewing the frontal sector, in addition to the sight of the course machine gun, but on the Ausf.B, Ausf.C and part of the Ausf.D, in place of the machine gun, there was a hatch with a viewing slot in it. Similar hatches were placed in the side plates on most Pz.Kpfw.IVs, being eliminated only on Ausf.J in connection with the installation of anti-cumulative screens. In addition, the driver had a turret position indicator, one of two lights warned of the turret turning to one side or another, in order to avoid damage to the gun when driving in cramped conditions.

For external communications, Pz.Kpfw.IV platoon commanders and above were equipped with a Fu 5 VHF radio station and a Fu 2 receiver. Line tanks were equipped only with a Fu 2 receiver. The FuG5 had a transmitter power of 10 W and provided a communication range of 9.4 km in telegraph and 6.4 km in telephone mode. For internal communication, all Pz.Kpfw.IVs were equipped with a tank intercom for four of the crew members, with the exception of the loader.

Good day! The ACES.GG team is with you, and today we will talk about the German medium tank of the fifth level Pz.Kpfw. IV Ausf. H. Consider its weak and strengths, we will analyze the performance characteristics, as well as the methods and tactics of using this machine in combat.

Tier 5 German medium tank Pz.Kpfw. IV Ausf. H can be opened with the tier 4 medium tank Pz.Kpfw. IV Ausf. D for 12,800 experience, as well as with the help of a light tank of the fourth level Pz.38 nA, but already for 15,000 experience. It will cost 373,000 credits at the time of purchase.

Let's analyze the performance characteristics of the Pz.Kpfw. IV ausf. H

Pz. IV H has an average HP of 480 at its level. Of course, this is not very much, but if you do not waste them, then it is quite enough. The dynamics of the tank is acceptable, it does not cause much discomfort. The tank is gaining its 40 km / h quite well. If we talk about armor, then the tank is not the best, especially in the stern and on the sides. But the tank may well take a hit, with proper use, from vehicles of its level and below. Also, the car has an acceptable visibility at its level, which is 350 meters.

Pz.Kpfw guns. IV ausf. H

Now let's talk about the guns, the tank has three of them to choose from.

The first is the 7.5 cm Kw.K. 40L/43. It is given to us in the stock configuration of the tank at the time of purchase. This weapon has no special advantages, not counting its rate of fire. But we will have to play with him until we open one of the following weapons.

Second gun 7.5 cm Kw.K. 40L/48. It can be considered the top one for this tank, of course, if you are not a fan of high explosives. This gun has acceptable armor penetration for its tier. Not the best, but still good accuracy, as well as a good rate of fire. The average damage per shot is 110 units, which is not too much, but again, for its level, this is quite an acceptable indicator.

And the third gun 10.5 cm Kw.K. L/28. The main advantage of this weapon is its cumulative shells. Penetration is 104 mm, which is enough to annihilate most of the enemies that the Pz.Kpfw will meet. IV Ausf. H. Also, do not forget about land mines, with the help of them we will be able to destroy weakly armored targets with one shot. Do not forget that this weapon has very poor accuracy, so it is advisable to always bring it to the end.

Equipment for Pz.Kpfw. IV ausf. H

The standard for me and the standard for many medium tanks

medium-caliber gun rammer, improved ventilation and reinforced aiming drives.

Skills and abilities of the Pz.Kpfw. IV ausf. H

Standard and good choice will be:

Commander - Sixth Sense, Repair, Combat Brotherhood.
Gunner - Repair, Smooth turn of the tower Combat Brotherhood.
Driver - Repair, Smooth running, Combat brotherhood.
Radio operator - Repair, Radio interception, Combat brotherhood.
Loader - Repair, Non-contact ammo rack, Combat Brotherhood.

My choice:

The choice of equipment Pz.Kpfw. IV ausf. H

Here is another standard, namely: a small repair kit, a small first aid kit and a hand-held fire extinguisher. I advise you to use premium equipment, which is quite expensive, but can significantly increase the survivability of your vehicle in battle. So feel free to put a large repair kit, a large first aid kit and an automatic fire extinguisher on your tank. You can also put a chocolate bar instead of an automatic fire extinguisher.

Tactics and style of play Pz.Kpfw. IV ausf. H

Tactics of the game on Pz. IV H depends on what levels of tanks you have to fight.

Pz.Kpfw. IV ausf. H in the top

On Pz. IV H in the top is best to take at the beginning of the battle good position at medium or long range, and shoot enemies caught in the light. You can also take part in the rush, if one is planned. The main thing to keep in mind is that there should be allies next to you who can cover you, as well as shelters for which you can leave after the shot in order to reload. Thanks to the rate of fire of the 7.5 cm gun, you can do quite good damage to the enemy, and with the 10.5 cm gun it will be possible to destroy lightly armored tanks with one shot. The main thing with all this is to try not to be substituted for the enemy’s shots.

Pz.Kpfw. IV ausf. H vs. sixth levels

In battles against the sixth levels, you can also act aggressively or passively. With an aggressive play style, it will be possible to support the allied rush by shooting at the enemies from behind the backs of the allies, or simply illuminate enemy tanks for allied vehicles. And with a passive style, you will need to take a place in the bushes and shoot damage at enemies caught in the light. Most importantly, we will need to avoid vehicles with high average damage per shot, such as the KV-2, KV-85 with a 122mm gun, and the like. After all, if they don’t kill us with one shot, they will make us crippled until the end of the battle.

Pz.Kpfw. IV ausf. H vs seventh levels

We will have nothing to do against the seventh levels on the front line, so it will be best to act from behind the backs of the allies on the second or third line. So we will be able to deal damage to enemies, while not receiving it ourselves, because many tanks of the seventh level will kill us with one or two shots. Well, if you don’t like this kind of gameplay, then you can try to gently drive forward towards fate, which will decide whether you bend over or just merge. But seriously, on the first line we will need to act very carefully, because in which case we will simply simply turn into an easy frag. Therefore, this tactic is extremely risky, but if everything is done correctly, then it can bear fruit.

Well, most importantly in any battle, you will need to be able to correctly analyze the map, team lineups, and the departure of your allies. Based on the analysis, it is already worth choosing the tactics and direction in which you will act. Also, do not forget to look at the minimap, so that if something happens, timely move to one or another direction where our help will be needed.

Outcome

Pz. IV H is a typical representative of medium tanks at their level, which are quite well balanced and deliver a lot of pleasant experience from playing them. The tank has quite a good potential, thanks to which it will be possible to influence the outcome of the battle. Also Pz. IV H, like many vehicles of the fifth level, is able to farm credits quite well and bring its owner a lot of pleasure from playing on it.

The first tanks Pz. 4 entered the Wehrmacht in January 1938. The total order for combat vehicles of this type included 709 tank units weapons.

The plan for 1938 provided for the settlement- rate of 116 tanks, and the firm Krupp almost you - filled it up by handing over 113 vehicles to the troops. The first "combat" operations with fate- eat Pz. IV became the Anschluss of Austria and the capture of the Sudetenland of Czechoslovakia in 1938. In March 1939, they marched through the streets of Prague.

On the eve of the invasion of Poland on September 1- In 1939, there were 211 tanks in the Wehrmacht Pz. four modifications A, B and C. According to the current staff, a tank division should have consisted of 24 tanks Pz. IV, 12 cars in each regiment. One- to the full state, only the 1st and 2nd tank regiments of the 1st tank were completed- division howl (1. Panzer Division). The Training Tank Battalion also had a full staff(Panzer Lehr Abteilung), attached 3rd tan- kov division. In other compounds, there were only a few Pz. IV, which - ry in armament and armor protection surpassed all types of opposing them Polish tanks. However, for the time- During the Polish campaign, the Germans lost 76 tanks of this type, 19 of them irretrievably.

By the beginning of the French campaign Pan- the cervaffe already had 290 Pz. IV and 20 bridge layers based on them. Like Pz. lll they were concentrated in the divisions operating in the directions of the main attacks. In the 7th Panzer Division of General Rommel, for example, there were 36 Pz. IV. During the fighting, the French and the English- we managed to knock out 97 tanks Pz. IV. Without - the return losses of the Germans amounted to only 30 combat vehicles of this type.

In 1940, the proportion of tanks Pz. IV in the tank formations of the Wehrmacht increased slightly. On the one hand, due to an increase in production, and on the other, due to a decrease in- Decreases the number of tanks in the division to 258 units.

To the beginning of Operation Barbarossa Ver- maht had 439 tanks Pz. IV, by the end of 1941, 348 of them were lost without return- military. Pz. IV, armed short barrel- guns, could not effectively- swarm with Soviet medium and heavy- our tanks. Only with the advent of the long-barrel modification did the situation level off. By the middle of 1943 Pz. IV became the main German tank on Vos- exact front. The staff of a German tank division included a two-battalion tank regiment. In the first battalion, two companies were armed Pz. IV, in the second, only one company. In general, the division- believed 51 tanks Pz. IV combat battalions - nah. In Operation Citadel, they were- whether almost 60% of the tanks that took part- tie in combat operations.

AT North Africa, up to the capital- battles of the German troops, Pz. IV successfully resisted all types of Union tanks- nicknames. Greatest Success these tanks reached in the fight against the British cray- Seri tanks A.9 and A. 10 - move- nym, but lightly armored. The first modification machines F 2 delivered to

North Africa in the summer of 1942. At the end of July, Rommel's African Corps- thought only 13 tanks Pz. IV , of which 9 were F 2. AT English documents that period they were called Panzer IV Special.

Despite the defeat at El Alamein, the Germans began to reorganize- stationing its forces in Africa. On December 9, 1942, the 5th Panzer Army was formed in Tunisia, in which, among- sneeze entered transferred from France

10th Panzer Division, which had- weapons tanks Pz. IV Ausf. G. These tanks participated in the defeat of the American troops at Kasserine on February 14, 1943. However, this was the last successful operation.- walkie-talkie of the Germans on the African continent- those - already on February 23 they were forced- we went on the defensive, their forces were rapidly dwindling. On May 1, 1943 in the German troops- kah in Tunisia there were only 58 tanks - of which 17 Pz. IV.

In 1944, the organization of the German tank- howling division has undergone significant changes. The first battalion of the tank regiment received tanks Pz. V "Panther", WTO - the swarm was completed Pz. IV. In fact, the "panthers" entered the army- not all tank divisions of the Wehrmacht- that. In a number of formations, both battalions had only Pz. IV.

In the summer of 1944, German troops Terpe- whether defeat after defeat, as per- pade, so in the East. I comply- there were also losses: only in two- six months - August and September - 1139 tanks were hit Pz. IV. However, me- her, their number in the troops continued to- be significant. In November 1944 Pz. IV accounted for 40% of German tanks on the Eastern Front, 52% - to the West- nom and 57% - in Italy.

The last major operations of the German army involving Pz. IV began a counteroffensive in the Ardennes in December 1944 and a counterattack of the 6th tank army SS in the area of ​​Lake Balaton in January - March 1945, ended Provo- scrap. During January 1945 alone, 287 Pz. IV, of which revolt - renovated and returned to service May 53- tires.

Pz. IV took part in the fighting before last days war, including street fighting in Berlin. On the territory of Czechoslovakia, fighting with fate- The use of tanks of this type continued until May 12, 1945.

tank losses Pz. IV amounted to 7636 units.

Pz. IV in much larger quantities- wah than other German tanks, postav- went for export. According to the German hundred- statistics, the allies of Germany, as well as Turkey and Spain received in 1942 - 1944. 490 combat vehicles. Beyond Ger- Mania Pz. IV were in service in Hungary (74, according to other sources - 104 units), Romania (142), Bulgaria (97), Fin- Landia (14) and Croatia.

Based on the Pz. IV produced self-propelled artillery mounts, commanders- kie tanks, advanced artillery vehicles- Russian observers, evacuation tractors and bridge tanks.

After the surrender of Germany, a large batch of 165 Pz. IV was handed over to Che- Khoslovakia. Having undergone repairs, they are- whether in service with the Czechoslovak army until the early 1950s. Except Czechoslovakia in the post-war years Pz. IV operated in the armies of Spain, Turkey, France, Finland, Bulgaria and Syria.

No one at the Krupp factory in 1936 could have imagined that this massive vehicle, equipped with a short-barreled infantry support cannon and considered auxiliary, would be so widely used in bulk tank ever produced in Germany, whose production volumes, despite the shortage of materials, grew until the very last days of the Second World War in Europe.

Wehrmacht work horse

Despite the fact that combat vehicles appeared that were more modern than the German T-4 tank - Tiger, Panther and King Tiger, it not only amounted to most weapons of the Wehrmacht, but was also part of many elite divisions of the SS. 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 armaments than the Panzer III. From Model A to F1, the early modifications that used a short 75mm barrel were gradually replaced by "long" ones, F2 to H, with a very effective high-velocity cannon inherited from the Pak 40, which 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

It was originally assumed that the German tank T-4, specifications which were identified in 1934 by the Waffenamt, will serve as "accompanying 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 to become an infantry support tank and be 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 the move smoother, but the need for a new tank stopped further developments. Krupp is back for more traditional system with four twin wheel bogies and leaf springs for easy 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 by the Ordnance Department ground forces as Versuchskraftfahrzeug 622. Nevertheless, in the new pre-war nomenclature, it quickly became known as Pz.Kpfw.IV (Sd.Kfz. 161).

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 velocity 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. with., as well as the 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. Total weight amounted to 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 for testing one Panzer prototype 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 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. The characteristics of the early F model, renamed F1 when the next one appeared, changed due to the replacement of the front appliqué plate with a 50 mm plate and the increase in the thickness of the hull and turret sides to 30 mm. The total weight of the tank grew to over 22 tons, which caused other changes, such as an increase in the width of the tracks from 380 to 400 mm to reduce ground pressure, with a corresponding replacement of the two idlers and drive 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 gun could not resist well 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, whose effectiveness 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 production 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. starting speed 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 strengthened with a new 30 mm plate, which in total increased the thickness to 80 mm. This turned out to be 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 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. Turret viewing slots were eliminated, engine ventilation and ignition at low temperatures were improved, additional holders for spare wheels and cleats 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 cannon KwK 40L/48. 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.

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.
