The Germans themselves did not have a high opinion of the fighting qualities of the Pz.lV. Here is what Major General von Mellenthin writes about this in his memoirs (in 1941, with the rank of major, he served on Rommel’s headquarters): “The T-IV tank gained a reputation among the British as a formidable enemy mainly because it was armed with a 75-mm cannon However, this gun had a low muzzle velocity and weak penetration, and although we used the T-IV in tank battles, they brought much greater benefit as a means of fire support for infantry." Pz.lV began to play a more significant role in all theaters of military operations only after the acquisition " long arm" - 75-mm KwK 40 guns (F2 series). On the Eastern Front, Pz.lV Ausf.F2 also appeared in the summer of 1942 and took part in the attack on Stalingrad and the North Caucasus. After production of the Pz.lll "four" ceased in 1943 gradually becoming the main German tank in all theaters of combat. However, in connection with the start of production of the Panther, it was planned to stop production of the Pz.lV, however, thanks to the tough position of the Inspector General of the Panzerwaffe, General G. Guderian, this did not happen. Subsequent events showed that that he was right..

Increased sharply combat characteristics Pz.IV after installing a long-barreled gun. Not inferior to enemy tanks in all other respects, the “four” turned out to be capable of hitting Soviet and American tanks out of range of their guns. We are not talking about English cars - for four years of the war the British were marking time. Until the end of 1943, the combat characteristics of the T-34 remained virtually unchanged, with the Pz.IV taking first place among medium tanks. Since 1942, the tactical and technical characteristics of the Pz.IV have not changed (except for the thickness of the armor) and during the two years of the war they remained unsurpassed by anyone! Only in 1944, having installed a 76-mm long-barreled gun on the Sherman, did the Americans catch up with the Pz.IV, and we, having launched the T-34-85 into production, overtook it. The Germans no longer had any time or opportunity left for a worthy response. Comparing the characteristics of WWII tanks, we can conclude that the Germans, before others, began to consider the tank as the main and most effective anti-tank weapon, and this is main trend post-war tank building.

In general, it can be argued that of all the German tanks of the Second World War, the Pz.IV was the most balanced and versatile. In this car various characteristics harmoniously combined and complemented each other. The "Tiger" and "Panther", for example, had a clear bias towards protection, which led to their overweight and deterioration in dynamic characteristics. The Pz.III, with many other characteristics being equal to the Pz.IV, did not match it in armament and, having no reserves for modernization, left the stage. The Pz.IV, with a similar Pz.III, but a slightly more thoughtful layout, had such reserves in full least. This is the only wartime tank with a 75 mm cannon, whose main armament was significantly strengthened without changing the turret. The turret of the T-34-85 and Sherman had to be replaced, and, by and large, these were almost new vehicles. The British went their own way and, like a fashionista, changed not the towers, but the tanks! But “Cromwell,” which appeared in 1944, never reached the “four,” as did “Comet,” released in 1945. Only the post-war Centurion was able to bypass the German tank, created in 1937.

From the above, of course, it does not follow that the Pz.IV was an ideal tank. Let's say it had insufficient engine power and a rather rigid and outdated suspension, which negatively affected its maneuverability. To some extent, the latter was compensated for by the lowest L/B ratio of 1.43 among all medium tanks. The equipping of the Pz.lV (as well as other tanks) with anti-cumulative screens cannot be considered a successful move by German designers. In droves cumulative ammunition were rarely used, the screens increased the dimensions of the vehicle, making it difficult to move in narrow passages, blocked most surveillance devices, and made it difficult for the crew to board and disembark.
However, an even more pointless and rather expensive measure was coating the tanks with Zimmerit (anti-magnetic painting, against magnetic mines). But perhaps the biggest mistake the Germans made was trying to switch to a new type of medium tank - the Panther. It did not take place as the latter, joining the Tiger in the class of heavy vehicles, but it played a fatal role in the fate of the Pz.lV. Having concentrated all their efforts on creating new tanks in 1942, the Germans stopped seriously modernizing the old ones. Let's try to imagine what would have happened if not for the Panther? The project of installing a “Panther” turret on the Pz.lV is well known, both standard and “close” (Schmall-turm). The project is quite realistic in size - the clear diameter of the turret ring for the Panther is 1650 mm, for the Pz.lV it is 1600 mm. The tower stood up without expanding the turret box. The situation with the weight characteristics was somewhat worse - due to the long reach of the gun barrel, the center of gravity shifted forward and the load on the front road wheels increased by 1.5 tons. However, it could be compensated for by strengthening their suspension. In addition, it must be taken into account that the KwK 42 cannon was created for the Panther, and not for the Pz.IV. For the "four" it was possible to limit ourselves to a gun with smaller weight and dimensions, with a barrel length of, say, not 70, but 55 or 60 calibers. Even if such a weapon would require replacing the turret, it would still make it possible to get by with a lighter design than the Panther one. The inevitably increasing (by the way, even without such a hypothetical rearmament) weight of the tank required replacing the Engine. For comparison: the dimensions of the HL 120TKRM engine installed on the Pz.IV were 1220x680x830 mm, and the Panther HL 230P30 - 1280x960x1090 mm. The clear dimensions of the engine compartments were almost identical for these two tanks. The Panther's was 480 mm longer, mainly due to the inclination of the rear hull plate. Consequently, equipping the Pz.lV with a higher power engine was not an insurmountable design task. The results of this, of course, far from complete, list of possible modernization measures would be very sad, since they would nullify the work on creating the T-34-85 for us and the Sherman with a 76-mm cannon for the Americans. In 1943-1945, the industry of the Third Reich produced about 6 thousand “Panthers” and almost 7 thousand Pz.IV. If we take into account that the labor intensity of manufacturing the Panther was almost twice that of the Pz.lV, then we can assume that during the same time German factories could produce an additional 10-12 thousand modernized "fours" that would be delivered to the soldiers anti-Hitler coalition much more trouble than the Panthers.

Combat use of medium tanks Pz Kpfw IV

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

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

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

In 1942 tank battalion Pz Kpfw IV was to consist of four tank companies of 22 Pz Kpfw IV plus eight tanks in the regiment's headquarters company.

Characteristic features of the turret of the Pz.IV Ausf.J tank

The given production data for Pz.IV, unfortunately, cannot be considered absolutely accurate. IN different sources Data on the number of cars produced vary, and sometimes noticeably. So, for example, I.P. Shmelev in his book “Armored Vehicles of the Third Reich” gives the following figures: Pz.IV with KwK 37 - 1125, and with KwK 40 - 7394. Just look at the table to see the discrepancies. In the first case, insignificant - by 8 units, and in the second, significant - by 169! Moreover, if we sum up the production data by modification, we get the number of 8714 tanks, which again does not coincide with the total of the table, although the error in this case is only 18 vehicles.

Pz.IV was exported in much larger quantities than other German tanks. Judging by German statistics, Germany's allies, as well as Turkey and Spain, received 490 combat vehicles in 1942–1944.

The first Pz.IV was received by the most faithful ally of Nazi Germany - Hungary. In May 1942, 22 Ausf.F1 tanks arrived there, and in September - 10 F2. The largest batch was delivered in the fall of 1944 - spring of 1945; according to various sources, from 42 to 72 vehicles of the H and J modifications. The discrepancy occurred because some sources question the fact that the tanks were delivered in 1945.

In October 1942, the first 11 Pz.IV Ausf.Gs arrived in Romania. Subsequently, in 1943–1944, the Romanians received another 131 tanks of this type. They were used in combat operations both against the Red Army and against the Wehrmacht, after Romania switched to the side of the anti-Hitler coalition.

A batch of 97 Ausf.G and H tanks was sent to Bulgaria between September 1943 and February 1944. From September 1944 they accepted Active participation in battles with German troops, being the main striking force of the only Bulgarian tank brigade. In 1950, the Bulgarian army still had 11 combat vehicles of this type.

In 1943, Croatia received several Ausf.F1 and G tanks; in 1944 14 Ausf.J - Finland, where they were used until the early 60s. At the same time, the standard MG 34 machine guns were removed from the tanks, and Soviet DTs were installed instead.

PRODUCTION Panzer TANK IV

DESIGN DESCRIPTION

The layout of the tank is classic, with a front-mounted transmission.

The control compartment was located in front of the combat vehicle. It housed the main clutch, gearbox, turning mechanism, controls, control instruments, a directional machine gun (with the exception of modifications B and C), a radio station and workplaces for two crew members - the driver and the gunner-radio operator.

The fighting compartment was located in the middle part of the tank. Here (in the turret) there was a cannon and a machine gun, observation and aiming devices, vertical and horizontal aiming mechanisms and seats for the tank commander, gunner and loader. The ammunition was placed partly in the turret and partly in the hull.

In the engine compartment, at the rear of the tank, there was an engine and all its systems, as well as an auxiliary engine for the turret rotation mechanism.

FRAME The tank was welded from rolled armor plates with surface cementation, generally located at right angles to each other.

In the front part of the roof of the turret box there were manholes for the driver and gunner-radio operator, which were closed with rectangular covers that hinged. Modification A has double-leaf lids, while the others have single-leaf lids. Each cover had a hatch for launching signal flares (with the exception of options H and J).

Pz.IV Ausf.F1. The hatch covers (driver and machine gunner) with round hatches for launching signal flares are clearly visible. A half-cylinder welded to the side of the body before laying the spare rollers closes the exhaust hole of the brake cooling system.

In the frontal plate of the hull on the left there was a driver's viewing device, which included a triplex glass block, closed by a massive armored sliding or folding flap Sehklappe 30 or 50 (depending on the thickness of the frontal armor), and a binocular periscope observation device KFF 2 (for Ausf. A - KFF 1). The latter, when there was no need for it, moved to the right, and the driver could observe through the glass block. Modifications B, C, D, H and J did not have a periscope device.

On the sides of the control compartment, to the left of the driver and to the right of the gunner-radio operator, there were triplex viewing devices, covered with hinged armored covers.

There was a partition between the rear of the hull and the fighting compartment. There were two hatches in the roof of the engine compartment, closed with hinged covers. Starting with Ausf.F1, the covers were equipped with blinds. In the reverse bevel of the left side there was an air inlet window to the radiator, and in the reverse bevel of the right side there was an air outflow window from the fans.

Layout of the Pz.IV tank:

1 - tower; 2 - commander's cupola; 3 - equipment box; 4 - rotating floor of the fighting compartment; 5 - fans; 6 - engine; 7 - fan drive pulley; 8 - exhaust manifold; 9 - muffler for turret rotation engine; 10 - muffler; 11 - guide wheel; 12 - suspension trolley; 13 - cardan shaft; 14 - gearbox; 15 - gear shift lever; 16 - drive wheel.

Reservation scheme for the Pz.IV medium tank.

TOWER- welded, hexagonal, mounted on a ball bearing on the turret plate of the hull. In its front part, in the mask, there was a cannon, a coaxial machine gun and a sight. To the left and right of the mask there were observation hatches with triplex glass. The hatches were closed with external armored flaps from inside the turret. Starting with modification G, the hatch to the right of the gun was missing.

The tower was driven by an electromechanical turning mechanism with a maximum speed of 14 degrees/s. A full revolution of the tower was carried out in 26 s. The flywheels of the turret's manual drive were located at the gunner's and loader's workstations.

The rear part of the Ausf.E modification turret.

At the rear of the tower roof there was a commander's cupola with five viewing slots with triplex glass. From the outside, the viewing slots were closed with sliding armor flaps, and the hatch in the turret roof, intended for the tank commander to enter and exit, was closed with a double-leaf lid (later - single-leaf). The turret had a dial-hour type device for determining the target location. A second similar device was at the gunner’s disposal and, having received an order, he could quickly turn the turret towards the target.

At the driver's seat there was a turret position indicator with two lights (except for Ausf.J tanks), thanks to which he knew what position the turret and gun were in (this is especially important when driving through wooded areas and populated areas).

For boarding and disembarking crew members, there were hatches on the sides of the turret with single-leaf and double-leaf (starting with version F1) covers. Inspection devices were installed in the hatch covers and sides of the tower. The turret's rear plate was equipped with two hatches for firing personal weapons. Due to the installation of screens, some vehicles of modifications H and J were missing inspection devices and hatches.

Hitler, surrounded by senior Wehrmacht and SS officers, inspects one of the first Ausf.F2 tanks, Berlin, April 4, 1942.

WEAPONS. The main armament of tanks of modifications A - F1 is a 7.5-cm KwK 37 cannon of 75 mm caliber from Rheinmetall-Borsig. The length of the gun barrel is 24 caliber (1765.3 mm). Gun weight - 490 kg. Vertical aiming - ranging from -10° to +20°. The gun had a vertical wedge breech and an electric trigger. Its ammunition included smoke rounds (weight 6.21 kg, starting speed 455 m/s), high-explosive fragmentation (5.73 kg, 450 m/s), armor-piercing (6.8 kg, 385 m/s) and cumulative (4.44 kg, 450...485 m/s) shells.

On January 11, 1934, at a meeting of the Wehrmacht Armament Directorate, the basic principles of arming tank divisions were approved. Soon after this, a prototype of the future was born tank PzKpfw IV, which for conspiracy purposes was called the already familiar definition of “medium tractor” - Mittleren Tractor. When the need for secrecy disappeared and the combat vehicle began to be openly called the tank of the battalion commander - Batail-lonfuhrerswagen (BW).

This name lasted until the introduction of a unified designation system for German tanks, when BW finally became medium tank PzKpfw IV. Medium tanks were supposed to serve as infantry support. The weight of the vehicle was not supposed to exceed 24 tons, and it was supposed to be armed with a short-barreled 75-mm cannon. It was decided to borrow the general layout, the thickness of the armor plates, the principle of crew placement and other characteristics from the previous tank - PzKpfw III. Work on creating a new tank began in 1934. The Rheinmetall-Borsig company was the first to present a plywood model of the future machine, and the following year a real prototype appeared, designated VK 2001/Rh.

The prototype was made of mild welded steel and weighed approximately 18 tons. No sooner had he left the walls of the manufacturing plant than he was immediately sent for testing to Kummersdorf. (It was in Kummersdorf that Adolf Hitler first became acquainted with Wehrmacht tanks. During this familiarization trip, Hitler showed great interest in the issues of motorization of the army and the creation of armored forces. Chief of Staff of the Armored Forces Guderian arranged demonstration tests of motorized mechanized forces for the Reich Chancellor. Hitler was shown motorcycle and anti-tank platoons , as well as platoons of light and heavy armored vehicles. According to Guderian, the Fuhrer was very pleased with the visit.)

PzKpfw IV and PzKpfw III tanks at Tankfest in Bovington

Daimler-Benz, Krupp and MAN also built their prototypes of the new tank. Krupp presented combat vehicle, almost similar to the prototype of the platoon commander’s vehicle they had previously proposed and rejected. After the tests, the technical department of the tank forces chose the VK 2001/K version, proposed by Krupp, for mass production, making minor changes to its design. In 1936, the first prototype of the 7.5 cm Geschiitz-Panzerwagen tank (VsKfz 618) was built, an armored vehicle with a 75 mm cannon (experimental model 618).

The initial order was for 35 vehicles, which were produced by the Friedrich Krupp AG factories in Essen between October 1936 and March 1937. Thus began the production of the most massive German tank, which remained in service with the armored forces of the Third Reich until the very end of the war. The PzKpfw IV medium tank owes its high combat characteristics entirely to the designers, who brilliantly coped with the task of enhancing the armor and firepower of the tank without making significant changes to the basic design.

MODIFICATIONS OF THE PzKpfw IV TANK

Tank PzKpfw IV Ausf A became the model for the creation of all subsequent modifications. The armament of the new tank consisted of a 75mm KwK 37 L/24 cannon, coaxial with a turret machine gun, and a front-mounted machine gun located in the hull. The power plant was a 12-cylinder carburetor liquid-cooled Maybach HL 108TR engine, which developed a power of 250 hp. The hull also housed an additional engine that drove an electric generator, which provided power to the electric drive for rotating the turret. The combat weight of the tank was 17.3 tons, the thickness of the frontal armor reached 20 mm.

A characteristic feature of the Pz IV Ausf A tank was the cylindrical commander's cupola with eight viewing slots covered with armored glass blocks.

Chassis applied to one side, it consisted of eight road wheels, interlocked in pairs into four bogies, suspended on quarter-elliptical leaf springs. There were four small road wheels on top. Drive wheel - front location. The guide wheel (sloth) had a mechanism for tensioning the tracks. It should be noted that this design of the chassis of the PzKpfw IV Ausf A tank was practically not subject to significant changes in the future. Tank PzKpfw IV Ausf A - the first serial tank of this type.

The following tank modification: PzKpfw IV Ausf B- featured an improved Maybach HL 120TRM engine with a power of 300 hp. at 3000 rpm and a new six-speed ZFSSG 76 gearbox instead of the five-speed SSG 75. The main difference between the PzKpfw FV Ausf B was the use of a straight body plate instead of the broken one of its predecessor. At the same time, the front-mounted machine gun was dismantled. In its place was a radio operator’s viewing device, which could fire personal weapons through the loophole. Frontal armor increased to 30 mm, due to which the combat weight increased to 17.7 tons. The commander's cupola also underwent changes, whose viewing slots were covered with removable covers. The order for the new “four” (still called 2/BW) was 45 vehicles, however, due to a lack of necessary parts and materials, the Krupp company was able to produce only 42.

German medium tank PzKpfw IV Ausf B

Tanks PzKpfw IV version Ausf C appeared in 1938 and differed very little from the Ausf B vehicles. Externally, these tanks are so similar that it can be very difficult to distinguish them. An additional similarity with the previous version is given by a straight frontal plate without an MG machine gun, instead of which an additional viewing device has appeared. Minor changes affected the introduction of an armored casing for the barrel of the MG-34 machine gun, as well as the installation of a special bumper under the gun, which bent the antenna when turning the turret, preventing it from breaking. In total, approximately 140 units of 19-ton Ausf C tanks were produced.

German medium tank PzKpfw IV Ausf C

Tanks of the next model - PzKpfw IV D- received an improved design of the gun mantlet. The practice of using tanks forced a return to the original design of a broken front plate (as on the PzKpfw IV Ausf A tanks). The front machine gun mount was protected by a square armor casing, and the side and rear armor increased from 15 to 20 mm. After the new tanks were tested, the following entry appeared in the military circular (No. 685 dated September 27, 1939): “PzKpfw IV (with a 75-mm cannon) SdKfz 161 is from now on declared suitable for successful use in military formations.” .

German medium tank PzKpfw IV Ausf D

A total of 222 Ausf D tanks were produced, with which Germany entered the Second World War. world war. During the Polish campaign, several “fours” ingloriously returned from the battlefields to their homeland for repairs and modifications. It turned out that the thickness of the armor of the new tanks was insufficient to ensure their safety, so additional armor plates were urgently required to protect the most important components. It is curious that in the reports of the English military intelligence At that time, there was an assumption that the strengthening of the combat armor of tanks often took place “illegally”, without corresponding orders from above, and sometimes even in spite of it. Thus, an order from the German military command intercepted by the British strictly prohibited the unauthorized welding of additional armor plates onto the hulls of German tanks. The order explained that “makeshift* fastening of armor plates does not increase, but reduces the protection of the tank, therefore the Wehrmacht command ordered commanders to strictly follow the instructions regulating the work to enhance the armor protection of combat vehicles.

German medium tank PzKpfw IV Ausf E

Soon the long-awaited “quartet” was born PzKpfw IV Ausf E, the design of which took into account all the previously identified shortcomings of the PzKpfw IV Ausf D. First of all, this related to increased armor protection. Now the 30 mm frontal armor of the hull was protected by additional 30 mm plates, and the sides were covered with 20 mm sheets. All these changes led to the fact that the combat weight increased to 21 tons. In addition, the Pz-4 Ausf E tanks had a new commander's cupola, which now almost did not extend beyond the turret. The course machine gun received a Kugelblende 30 ball mount. A box for spare parts and equipment was mounted on the rear wall of the turret. The chassis used new simplified drive wheels and wider tracks of a new type with a width of 400 mm instead of the old ones with a width of 360 mm.

German medium tank PzKpfw IV Ausf F1

The next option was a tank PzKpfw IV Ausf F1. These tanks had a solid front plate 50 mm thick and 30 mm sides. The forehead of the turret also received 50 mm armor. This tank became latest model, armed with a short-barreled 75 mm cannon with a low muzzle velocity.

German medium tank PzKpfw IV Ausf F2

Soon, Hitler personally ordered the replacement of this ineffective gun with a long-barreled 75-mm KwK 40 L/43 - thus the medium tank was born PzKpfw IV F2. The new weapon required changes to the design of the turret's fighting compartment in order to accommodate the increased ammunition load. 32 shots out of 87 were now placed in the turret. The initial speed of a conventional armor-piercing projectile has now increased to 740 m/s (versus 385 m/s for the previous gun), and armor penetration has increased by 48 mm and amounted to 89 mm versus the previous 41 mm (with an armor-piercing projectile at a range of 460 meters at an impact angle of 30°) . The new powerful weapon immediately and forever changed the role and place of the new tank in the German armored forces. In addition, the PzKpfw IV received a new Turmzielfernrohr TZF Sf sight and a gun mantlet of a different shape. From now on, the PzKpfw III medium tank fades into the background, content with the role of an infantry support and escort tank, and the PzKpfw IV for a long time becomes the main “assault” tank of the Wehrmacht. In addition to Krupp-Gruson AG, two more enterprises joined the production of PzKpfw IV tanks: VOMAG and Nibelungenwerke. The appearance on the stage of the theater of operations of the modernized Pz IV “fours” significantly complicated the position of the allies, since new gun allowed the German tank to successfully fight against most of the armored vehicles of the USSR and coalition member countries. In total, 1,300 early Ausf fours (from A to F2) were produced during the period until March 1942.

PzKpfw IV is called the main tank of the Wehrmacht. More than 8,500 “fours” formed the basis of the Wehrmacht’s tank forces, its main striking force.

The next large-scale version was the tank PzKpfw IV Ausf G. From May 1942 to June 1943, much more of them were created than vehicles of previous modifications, more than 1,600 units.

German medium tank PzKpfw IV Ausf G

The very first Pz IV Ausf Gs were practically no different from the PzKpfw IV F2, but during the production process numerous changes were made to the basic design. First of all, this concerns the installation of a 75-mm KwK 40 L/48 cannon with a two-chamber muzzle brake. The upgraded version of the KwK 40 tank gun had an initial projectile speed of 750 m/s. The new model of the Quartet tank was equipped with additional 5-mm protective screens to protect the turret and sides of the hull, which received the humorous nickname “apron” among the troops. The Pz Kpfw IV Aufs G tank, produced since March 1943, was armed with a 75-mm cannon with a barrel length of L/48 instead of the previous one with a barrel length of 43 calibers. A total of 1,700 vehicles of this modification were produced. Despite the increased armament, the PZ-4 still could not compete with the Russian T-34.
Weak armor protection made them too vulnerable. In this photo you can see how the Pz Kpfw IV Ausf G tank uses sandbags as additional protection. Of course, such measures could not significantly improve the situation.

The most popular series was the tank PzKpfw IV Ausf N, more than 4,000 of them were produced, including various self-propelled guns created on the T-4 (“four”) chassis.

German medium tank PzKpfw IV Ausf H

This tank was distinguished by the most powerful frontal armor (up to 80 mm), the introduction of 5-mm side screens of the hull and turret, the MG-34 -Fliegerbeschussgerat 41/42 anti-aircraft machine gun mount mounted on the commander's turret, a new, improved ZF SSG 77 gearbox and minor changes in the transmission. The combat weight of this modification of the Pz IV reached 25 tons. The latest version of the Quartet was the tank PzKpfw IV J, which continued to be produced until March 1945. From June 1944 to March 1945, more than 1,700 of these vehicles were produced. Tanks of this type were equipped with high-capacity fuel tanks, which increased the cruising range to 320 km. However, in general, the latest “fours” have been significantly simplified compared to previous models.

DESCRIPTION OF THE PzKpfw IV TANK DESIGN

TURRET AND HULL OF TANK Pz IV

The hull and turret of the Pz-4 tank were welded. There were evacuation hatches on each side of the tower for boarding and disembarking crew members.

The tower was equipped with a commander's cupola with five viewing slots equipped with armored glass blocks - triplex and protective armor covers, which were lowered and raised using a small lever located under each slot.

The tower's pole rotated with her. The armament consisted of a 75-mm (short-barreled KwK 37 or long-barreled KwK 40) cannon and a coaxial turret machine gun, as well as an MG course machine gun mounted in the frontal armor of the hull in a ball mount and intended for the radio operator. This armament scheme is typical for all modifications of the “fours” with the exception of version C tanks.

Layout of the PzKpfw IV tank- classic, with front transmission. Inside, the tank hull was divided into three compartments by two bulkheads. The rear compartment contained the engine compartment.

As in other German tanks, a cardan shaft was thrown from the engine to the gearbox and drive wheels, running under the turret floor. Next to the engine was an auxiliary engine for the turret rotation mechanism. Because of this, the turret was shifted to the left along the axis of symmetry of the tank by 52 mm. Three fuel tanks with a total capacity of 477 liters were installed on the floor of the central fighting compartment, under the floor of the turret. The fighting compartment turret housed the remaining three crew members (commander, gunner and loader), weapons (a cannon and a coaxial machine gun), observation and aiming devices, vertical and horizontal guidance mechanisms. The driver and radio operator firing from a machine gun mounted in a ball joint were located in the front compartment of the hull, on both sides of the gearbox.

Armor thickness of the PzKpfw IV tank was constantly increasing. The frontal armor of the T-4 was welded from rolled armor plates with surface cementation and was usually thicker and stronger than the side armor. Additional protection using armor plates was not used until the creation of the Ausf D tank. To protect the tank from bullets and cumulative shells, zimmerit coating was applied to the lower and side surfaces of the hull and the side surfaces of the turret. Testing of the T-4 Ausf G carried out by the British using the Brinell method gave the following results: front front plate in an inclined plane (outer surface) - 460-490 HB; front vertical plate (outer surface) - 500-520 HB; inner surface-250-260 HB; tower forehead (outer surface) - 490-51 0 HB; hull sides (outer surface) - 500-520 HB; inner surface - 270-280 HB; tower sides (outer surface) -340-360 HB. As mentioned above, on the “fours” latest versions additional armored “screens” were used, made of steel sheets measuring 114 x 99 cm and mounted on the sides of the hull and turret, at a distance of 38 cm from the hull. The turret was protected by 6 mm thick armor plates attached around the rear and sides, and the protective screen had hatches located exactly in front of the turret hatches.

TANK ARMAMENT.

The PzKpfw IV Ausf A - F1 tanks were equipped with a short-barreled 75-mm KwK 37 L/24 cannon with a 24-caliber barrel length, a vertical bolt and an initial projectile velocity not exceeding 385 m/s. The PzKpfw III Ausf N tanks and StuG III assault guns were equipped with exactly the same guns. The gun's ammunition included almost all types of shells: armor-piercing tracer, armor-piercing tracer sub-caliber, cumulative, high-explosive fragmentation and smoke.

To rotate the gun by the required 32° (from -110 to +21, 15 full revolutions were required. The Pz IV tanks used both an electric drive and a manual drive for turning the turret. The electric drive was powered by a generator driven by a two-cylinder two-stroke water-cooled engine. For rough For target designation, a dial-clock type system was used. For this, the angle of horizontal fire of the tank's turret gun, equal to 360°, was divided into twelve divisions, and the division corresponding to the traditional position of the number 12 on the clock dial indicated the direction of movement of the tank. Another transmission via a hinge shaft drove the gear ring in the commander's cupola was set in motion, this ring was also graduated from 1 to 12 a. In addition, the external scale of the cupola, corresponding to the dial of the main gun, was equipped with a fixed pointer.

Thanks to this device, the commander could determine the approximate location of the target and give appropriate instructions to the gunner. The driver's position was equipped with a turret position indicator (with two lights) on all models of the PzKpfw IV tank (except Ausf J). Thanks to this device, the driver knew the location of the turret and tank gun. This was especially important when moving through the forest and in populated areas. The gun was mounted together with a coaxial machine gun and a TZF 5v telescopic sight (on early modifications of tanks); TZF 5f and TZF 5f/l (on tanks starting with PzKpfw IV Ausf E tanks). The machine gun was powered from a flexible metal strip, and the shooter fired using a special foot pedal. The telescopic 2.5x sight was equipped with scales of three ranges (for the main gun and machine gun).

View of the front part of the turret of the Pz IV tank

The MG-34 course machine gun was equipped with a KZF 2 telescopic sight. The full ammunition load consisted of 80-87 (depending on modification) artillery rounds and 2,700 rounds of ammunition for two 7.92 mm machine guns. Starting with the Ausf F2 modification, the short-barreled gun is replaced by a more powerful long-barreled 75-mm KwK 40 L/43 cannon, and the latest modifications (starting with Ausf H) receive an improved L/48 gun with a barrel length of 48 calibers. The short-barreled guns had a single-chamber muzzle brake, while the long-barreled ones had to be equipped with two-chamber ones. Increasing the barrel length required a counterweight. To achieve this, the latest modifications of the Pz-4 were equipped with a heavy compression spring installed in a cylinder attached to the front of the rotating turret floor.

Engine and transmission

The first versions of the PzKpfw IV were equipped with the same engine as the tanks of the PzKpfw III series - the 12-cylinder Maybach HL 108 TR with a power of 250 hp, which required gasoline with an octane rating of 74. Subsequently, they began to use the tank as a power plant. improved Maybach HL 120 TR and HL 120 TRM engines with 300 hp power. The engine as a whole was distinguished by its high reliability and resistance to temperature changes, but this did not apply to the conditions of the African heat and the sultry regions of southern Russia. To avoid the engine boiling, the driver had to drive the tank with all possible caution. In winter conditions, a special installation was used that made it possible to pump heated liquid (ethylene glycol) from a working tank into a tank that needed to be started. Unlike PzKpfw tanks III engine in the T-4 it was located asymmetrically, on the right side of the hull. The small-link caterpillars of the T-4 tank consisted of 101 or 99 links (starting from F1) with a width (variants) of the PzKpfw IV Ausf A -E 360 mm, and in the Ausf F-J - 400 mm, their total weight was close to 1300 kg. The tension of the caterpillar was adjusted using rear guide wheel mounted on an eccentric axis. The ratchet mechanism prevented the axle from turning backward and causing the track to sag.

TRACK REPAIR.
Each crew of the Pz IV tank had at its disposal an industrial belt of the same width as the tracks. The edges of the belt were perforated so that the holes coincided with the teeth of the drive wheel. If the track failed, a belt was attached to the damaged area, passed over the support rollers and attached to the teeth of the drive wheel. After this, the engine and transmission were started. The drive wheel turned and pulled the track and belt forward until the track caught on the wheel. Anyone who has ever pulled off a heavy long caterpillar the “old-fashioned way” - using a piece of rope or fingers, will appreciate what a salvation this simple scheme was for the crew.

BATTLE RECORD OF Pz IV TANK

The “four” began their combat journey in Poland, where, despite their small numbers, they immediately became a noticeable striking force. On the eve of the invasion of Poland, there were almost twice as many “fours” in the Wehrmacht troops as “threes” - 211 versus 98. The fighting qualities of the “fours” immediately attracted the attention of Heinz Guderian, who from that moment on would constantly insist on increasing their production. Of the 217 tanks lost by Germany during the 30-day war with Poland, there were only 19 “fours”. In order to better imagine the Polish stage of the PzKpfw IV’s combat path, let’s turn to the documents. Here I want to introduce readers to the history of the 35th Tank Regiment, which took part in the occupation of Warsaw. I present to your attention excerpts from the chapter dedicated to the assault on the Polish capital, written by Hans Schaufler.

“It was the ninth day of the war. I have just joined the brigade headquarters as a liaison officer. We were standing in the small suburb of Ochota, located on the Rawa-Ruska-Warsaw road. Another attack on the Polish capital was coming. The troops are on full alert. The tanks were lined up in a column, with infantry and sappers behind them. We are waiting for the order to advance. I remember the strange calm that reigned among the troops. No rifle shots or machine gun fire were heard. Only occasionally the silence was broken by the rumble of a reconnaissance aircraft flying over the column. I was sitting in the command tank next to General von Hartlieb. To be honest, it was a bit cramped in the tank. The brigade adjutant, Captain von Harling, studied the topographic map with applied furnishings. Both radio operators clung to their radios. One listened to the message from the division headquarters, the second kept his hand on the key to immediately begin transmitting orders to the units. The engine purred loudly. Suddenly a whistle cut through the silence, the next second drowned out by a loud explosion. First it hit the right, then the left of our car, then from behind. Artillery came into action. The first groans and cries of the wounded were heard. Everything is as usual - the Polish artillerymen send us their traditional “hello”.
Finally the order was received to go on the offensive. The engines roared and the tanks moved towards Warsaw. Quite quickly we reached the suburbs of the Polish capital. Sitting in the tank, I heard the chatter of machine gun fire, the explosions of hand grenades and the clicking of bullets on the armored sides of our vehicle. Our radio operators received one message after another. “Forward to the street barricade*,” was transmitted from the headquarters of the 35th regiment. “Anti-tank gun - five tanks destroyed - there is a mined barricade ahead,” neighbors reported. “Order for the regiment! Turn straight south!" - thundered the general's bass. He had to yell above the hellish noise outside.

“Pass the message to division headquarters,” I ordered the radio operators. -We approached the outskirts of Warsaw. The streets are barricaded and mined. Turn right*. After some time, a short message comes from the regiment headquarters: -The barricades have been taken*.
And again the sound of bullets and loud explosions to the left and right of our tank... I feel like someone is pushing me in the back. “The enemy’s positions are three hundred meters ahead,” the general shouted. - Turn right!* The terrible grinding of caterpillars on the cobblestone street - and we enter a deserted square. -Faster, damn it! Even faster!* - the general shouts furiously. He's right, you can't hesitate - the Poles shoot very accurately. “We came under heavy artillery fire,” reports from the 36th Regiment. *3b regiment! - the general answers immediately. “Demand artillery cover immediately!” You can hear stones and shell fragments hitting the armor. The blows are getting stronger. Suddenly, a monstrous explosion is heard very close by, and I smash my head into the radio. The tank is tossed up and thrown to the side. The engine stalls.
Through the hatch cover I see a dazzling yellow flame.

Tank PzKpfw IV

IN fighting compartment everything is turned upside down, gas masks, fire extinguishers, camp bowls, and other little things are lying everywhere... A few seconds of eerie numbness. Then everyone shakes themselves, looks at each other anxiously, and quickly feels themselves. Thank God, alive and well! The driver engages third gear, we wait with bated breath for the familiar sound and take a breath of relief when the tank obediently moves away. True, there is a suspicious tapping noise coming from the right track, but we are too happy to take such trifles into account. However, as it turned out, our misfortunes were far from over. Before we had time to drive a few meters, a new strong shock shook the tank and threw it to the right. From every house, from every window we were bombarded with furious machine-gun fire. From the roofs and attics, the Poles threw hand grenades and incendiary bottles with condensed gasoline at us. There were probably a hundred times more enemies than there were, but we did not turn back.

We stubbornly continued to move in a southerly direction and neither the barricades of overturned trams, twisted barbed wire and rails dug into the ground could stop us. Every now and then our tanks came under fire anti-tank guns. “Lord, make sure they don’t knock out our tank!”- we silently prayed, fully aware that any forced stop would be the last in our lives. Meanwhile, the sound of the caterpillar became increasingly loud and threatening. Finally we drove into some kind of orchard and hid behind the trees. By this time, some units of our regiment managed to break through to the outskirts of Warsaw, but further advance became more and more difficult. Disappointing messages came over the radio every now and then: “The offensive was stopped by heavy enemy artillery fire - the tank hit a mine - the tank was hit by an anti-tank gun - artillery support is urgently required”.

We also did not manage to take a proper breath under the shade of the fruit trees. The Polish artillerymen quickly found their bearings and brought down a barrage of fierce fire on us. With every second the situation became more and more frightening. We tried to leave the shelter that had become dangerous, but it turned out that the damaged track had completely failed. Despite all our efforts, we could not even move. The situation seemed hopeless. It was necessary to repair the track on site. Our general could not even temporarily leave command of the operation; he dictated message after message, order after order. We sat idle... When the Polish guns fell silent for a while, we decided to take advantage of this short respite to inspect the damaged chassis. However, as soon as we opened the hatch cover, the fire resumed. The Poles settled somewhere very close and, remaining invisible to us, turned our car into an excellent target. After several unsuccessful attempts, we managed to climb out of the tank and, taking cover in the thorny blackberries, were finally able to inspect the damage. The results of the examination were most disappointing. The inclined frontal plate, bent by the explosion, turned out to be the most insignificant of all the damages. The chassis was in the most deplorable condition. Several sections of the tracks fell apart, with small metal parts getting lost along the way; the rest were kept on their word of honor. Not only the tracks themselves were damaged, but even the road wheels. With great difficulty, we somehow tightened up the loose parts, removed the tracks, fastened the torn tracks with new pins... It was obvious that even with the most favorable outcome, these measures would give us the opportunity to walk another couple of kilometers, but nothing more could be done in such conditions it was impossible. I had to climb back into the tank.

Even more unpleasant news awaited us there. The division headquarters reported that air support was impossible, and the artillery was not able to cope with the superior enemy forces. Therefore, we were ordered to return immediately.

The general led the retreat of his units. Tank after tank, platoon after platoon, ours retreated, and the Poles showered them with ferocious fire from their guns. In some areas, progress was so difficult that for some time we forgot about the deplorable condition of our tank. Finally, when the last tank got out of the suburb that had become hell, it was time to think about itself. After consulting, we decided to retreat along the same route we came in. At first everything went calmly, but in this calmness we felt some kind of hidden danger. The ominous silence got on the nerves much more than the sounds of cannonade that had become familiar. None of us doubted that it was no accident that the Poles were hiding, that they were waiting for the right moment to end our lives. Slowly moving forward, we felt with our skin the hateful gaze of an invisible enemy fixed on us... Finally we got to the place where we received the first damage. A few hundred meters away lay the highway leading to the division's location. But the path to the highway was blocked by another barricade - abandoned and silent, like the rest of the surrounding area. We carefully overcame the last obstacle, entered the highway and crossed ourselves.

And then a terrible blow fell on the poorly protected stern of our tank. It was followed by another and another... Four strikes in total. The worst thing happened - we came under targeted fire from an anti-tank gun. The engine roared and the tank made a desperate attempt to escape from the shelling, but in the next second we were thrown to the side by a strong explosion. The engine stalled.
The first thought was - it’s all over, the Poles will destroy us with their next shot. What to do? They jumped out of the tank and rushed to the ground. We are waiting for what will happen... A minute passes, then another... But for some reason there is no shot. What's the matter? And suddenly we look - there is a column of black smoke above the stern of the tank. The first thought is that the engine is on fire. But where does this strange whistling sound come from? We took a closer look and couldn’t believe our eyes - it turns out that a shell fired from the barricade hit smoke bombs located at the rear of our vehicle, and the breeze blew the smoke to the skies. What saved us was that a black cloud of smoke hung just above the barricade and the Poles decided that the tank was on fire.

Revived PzKpfw IV tank

*Brigade headquarters - division headquarters* - the general tried to get in touch, but the radio was silent. Our tank looked terrible - black, dented, with a mangled rear. The completely fallen off caterpillar was lying nearby... No matter how hard it was, I had to face the truth - I had to abandon the car and try to get to my people on foot. We pulled out machine guns, took walkie-talkies and folders with documents and last time looked at the mutilated tank. My heart sank with pain... According to the instructions, the damaged tank was supposed to be blown up so that it would not fall to the enemy, but none of us could decide to do this... Instead, we disguised the vehicle as best we could with branches. In our hearts, everyone hoped that if circumstances were favorable, we would soon return and tow the car to our people...
To this day I remember with horror the way back... Covering each other with fire, in short dashes, we moved from house to house, from garden to garden... When we finally got to ours in the evening, we immediately collapsed and fell asleep .
However, I never managed to get enough sleep. After some time, I opened my eyes in horror and went cold, remembering that we had abandoned our tank... I could see it standing, defenseless, with an open turret, right opposite the Polish barricade... When I woke up again from sleep, then I heard the hoarse voice of the driver above me: “Are you with us?” I didn’t understand, half asleep, and asked: “Where?” “I found a repair car,” he explained shortly. I immediately jumped to my feet, and we went to rescue our tank. It would take a long time to tell how we got there, how we labored over the resuscitation of our mangled car. The main thing is that that night we still managed to put our command “four” into action (The author of the memoirs is most likely mistaken in calling his tank “four”. The fact is that the Pz. Kpfw. IV tanks began to re-equip command vehicles only since 1944. Most likely we're talking about about the command tank based on Pz. Kpfw. III version D.)
When the awakened Poles tried to stop us with fire, we had already finished our work, so we quickly climbed into the tower and left. We were happy in our souls... Even though our tank was knocked out and badly damaged, we still could not abandon it to the joy of the triumphant enemy! A month-long campaign in conditions of poor Polish roads and loose, swampy soil had the most unfavorable effect on the condition of German tanks. The cars were in urgent need of repair and restoration. This circumstance, among others, influenced the postponement of the Hitler invasion to Western Europe. The Wehrmacht command was able to learn lessons from the experience of the war in Poland and made significant changes to the previously existing scheme for organizing the repair and maintenance of combat vehicles. About efficiency new system repair and restoration of Wehrmacht tanks can be judged by a newspaper article published in one of the German newspapers and reprinted in England in May 1941. The article was called “The Secret of the Combat Power of German Tanks” and contained a detailed list of measures to organize the uninterrupted operation of the repair and restoration service, which was part of in each tank division.
“The secret of the success of German tanks is largely determined by the impeccably organized system of evacuation and repair of damaged tanks, which allows all necessary operations to be carried out in the shortest possible time. The greater the distances that tanks have to cover during the march, the greater the importance of a flawlessly adjusted repair mechanism and technical support broken down machines.
1. Each tank battalion has at its disposal a special repair and restoration platoon for emergency care for minor damage. This platoon, being the smallest repair unit, is located in close proximity to the front line. The platoon includes engine repair mechanics, radio mechanics and other specialists. The platoon has at its disposal light trucks for transporting the necessary spare parts and tools, as well as a special armored repair and recovery vehicle, converted from a tank, for transporting these parts to the disabled tank. The platoon is commanded by an officer who, if necessary, can call for help from several such platoons and send them all together to the area where emergency assistance is required.

It should be especially emphasized that the efficiency of the repair and restoration platoon directly depends on the availability of the necessary spare parts, tools and appropriate transport. Since time is worth its weight in gold in combat conditions, the chief mechanic of a repair platoon always has at his disposal a supply of basic components, assemblies and parts. This allows him, without wasting a second, to be the first to go to the damaged tank and begin work, while the remaining supply of necessary materials is carried on the truck. If the damage received by the tank is so serious that it cannot be repaired on site, or repairs require for a long time, the car is sent back to the manufacturer.
2. Each tank regiment has at its disposal a repair and restoration company, which has everything necessary equipment and tools. In the mobile workshops of the repair company, experienced craftsmen carried out charging batteries, welding work and complex engine repairs. The workshops are equipped with special cranes, milling, drilling and grinding machines, as well as special tools for plumbing, carpentry, painting and tinsmithing. Each repair and restoration company includes two repair platoons, one of which can be assigned to a specific battalion of the regiment. In practice, both platoons are constantly moving around the regiment, ensuring the continuity of the recovery work cycle. Each platoon had its own truck for transporting spare parts. In addition, the repair and restoration company necessarily included a platoon of emergency repair and recovery vehicles, which deliver failed tanks to a repair shop or collection point, where the tank repair platoon or the entire company was then sent. In addition, the company also includes a weapons repair platoon and radio repair shops.

3. If well-equipped repair shops exist behind the front line or in territory occupied by us, troops often use them to save transport and reduce the volume of railway traffic. In such cases, all necessary spare parts and equipment are ordered from Germany, and a staff of highly qualified craftsmen and mechanics is assigned.
It can be said with all certainty that without a thoroughly thought-out and clearly functioning scheme for the work of repair units, our valiant tankers would not have been able to cover such vast distances and win such brilliant victories in a real war*.

Before the invasion of Western Europe, the Fours still constituted an absolute minority of Panzerwaffe tanks - only 278 out of 2,574 combat vehicles. The Germans were opposed by more than 3,000 Allied vehicles, most of which were French. Moreover, many french tanks at that time, they were significantly superior to even the “fours” so beloved by Guderian, both in terms of armor protection and weapons efficiency. However, the Germans had an undeniable advantage in strategy. In my opinion, the essence of "blitzkrieg" is best expressed in short phrase Heinz Guderian: “Don’t touch with your fingers, but hit with your fist!” Thanks to the brilliant implementation of the “blitzkrieg” strategy, Germany easily won the French campaign, in which the PzKpfw IV was very successful. It was at this time that German tanks managed to create a formidable reputation for themselves, many times exceeding the real capabilities of these weakly armed and insufficiently armored vehicles. There were especially many PzKpfw IV tanks in Rommel's Afrika Korps, but in Africa they were assigned an auxiliary role of infantry support for too long.
In February 1941, a review of the German press, regularly published in the British press, published a special selection dedicated to the new PzKpfw IV tanks. The articles indicate that each Wehrmacht tank battalion has at its disposal a company of ten PzKpfw IV tanks, which are used, firstly , as an assault artillery gun, and secondly, as essential element rapidly advancing tank columns. The first purpose of the PzKpfw IV tanks was explained simply. Since field artillery is not able to instantly support armored forces in one direction or another, the PzKpfw IV took on its role with its powerful 75 mm cannon. Other advantages of using the Quartet stemmed from the fact that its 75 mm gun, with a maximum firing range of more than 8,100 m, could dictate the time and place of battle, and the speed and maneuverability of the gun made it an extremely dangerous weapon.
The articles, in particular, contain examples of how six PzKpfw IV tanks were used as an artillery formation against the advancing Allied column, and how they were also used as weapons for counter-battery warfare, and also acted from an ambush, in which British tanks were lured by several German armored vehicles. In addition, PzKpfw IVs were also used in defensive operations, an example of which is the following episode of the African campaign. On June 16, 1941, the Germans surrounded British troops in the Capuzzo area. This was preceded by an unsuccessful attempt by the British to break through to Tobruk and recapture the fortress besieged by Rommel’s troops. On June 15, they rounded the mountain range southeast of the Halfaya pass and advanced northward through Ridot ta Capuzzo almost to Bardia. This is how a direct participant in the events from the British side recalls it:

“Armored vehicles stretched out along a wide front. They moved in twos or threes, and if they met serious resistance, they immediately turned back. The vehicles were followed by infantry in trucks. This was the start of a full-scale attack. Tank crews fired to kill, the fire accuracy was 80-90%. They positioned their tanks so that their front and sides faced our positions. This allowed the Germans to effectively hit our guns while remaining motionless. They rarely fired while moving. In some cases, PzKpfw IV tanks suddenly opened fire from their guns, and they did not shoot at any specific target, but simply creating a wall of fire as they moved at ranges of 2000-3600 m. All this was done in order to terrify the our defenders. To be honest, they succeeded quite well.”

The first clash between American and German troops in Tunisia occurred on November 26, 1942, when troops of the 190th Tank Battalion of the Afrika Korps in the Mateur area came into contact with the 2nd Battalion of the 13th Regiment of the 1st Tank Division. The Germans in this area had approximately three PzKpfw III tanks and at least six new PzKpfw IV tanks with long-barreled 75-mm KwK 40 guns. This is how this episode is described in the book “Old Ironsides”.
“While enemy forces were gathering from the north, Waters’ battalion wasted no time. Having dug deep lines of defense, camouflaged their tanks and done other necessary work, they not only had time to prepare for the meeting with the enemy, but even carved out an extra day of respite for themselves. The next day the head of a German column appeared. Siglin's company prepared to rush towards the enemy. An assault gun platoon under the command of Lieutenant Ray Wasker moved forward to intercept and destroy the enemy. Three 75-mm howitzers on the chassis of half-track armored personnel carriers, located on the edge of a dense olive grove, allowed the Germans to approach approximately 900 m and opened rapid fire. However, hitting enemy tanks was not such an easy task. The Germans quickly retreated and, almost completely hidden by clouds of sand and dust, responded with volleys of their powerful guns. The shells exploded very close to our positions, but for the time being did not cause any serious damage.

Soon Wasker received an order from the battalion commander to set fire to smoke bombs and withdraw his self-propelled guns. artillery installations to a safe distance. At this time, Siglin's company, consisting of 12 M3 General Stewart light tanks, attacked the enemy's western flank. The first platoon managed to break through closest to the enemy positions, but the Italo-German troops were not at a loss, quickly found the target and brought down the full power of their guns on it. In a matter of minutes, Company A lost six of its tanks, but despite this, it still managed to push back the enemy vehicles, turning them with their rear towards the positions of Company B. This played a decisive role in the battle. Company B brought down the fire of its guns on the most vulnerable spots of the German tanks and, without allowing the enemy to come to their senses, disabled six PzKpfw IVs and one PzKpfw III. The remaining tanks retreated in disarray (In order for the reader to feel the severity of the situation in which the Americans found themselves, it makes sense for comparison to cite the main performance characteristics of the M 3 Stuart light tank: combat weight - 12.4 tons; crew - 4 people; reservation - from 10 to 45 mm; armament - 1 x 37 mm tank gun; 5 x 7.62 mm machine guns; engine "Continental" W 670-9A, 7-cylinder, carburetor power 250 hp; speed - 48 km/h ; power reserve (on the highway) - 113 km.).
To be fair, it should be noted that the Americans did not always emerge victorious from fights with German tank forces. Much more often, circumstances turned out exactly the opposite, and the Americans had to suffer serious losses in military equipment and people. However, in this case they actually won a convincing victory.

Despite the fact that on the eve of the invasion of Russia, Germany significantly increased the production of PzKpfw IV tanks, they still accounted for no more than one sixth of all Wehrmacht combat vehicles (439 out of 3332). True, by that time the number of obsolete light tanks PzKpfw I and PzKpfw II had decreased significantly (thanks to the actions of the Red Army), and the majority of the Panzerwaffe began to be made up of Czech LT-38 (PzKpfw 38 (1) and German “troikas”. With such forces, the Germans began to implement "Barbarossa" plan. The certain superiority of the Soviet Union in military equipment did not confuse the strategists from the OKW too much, they had no doubt that German vehicles would quickly cope with this gigantic fleet of obsolete Russian tanks. At first it turned out that way, but the appearance on the stage of the theater of operations of a new Soviet medium tank T-34 and heavy KV-1, radically changed the situation. Before the creation of the Panthers and Tigers, not a single German tank could withstand competition with these magnificent tanks. At close ranges they literally shot weakly armored German technology. The situation changed somewhat with the appearance in 1942 of a new “four”, armed with a long-barreled 75-mm KwK 40 cannon. Now I want to introduce you to an excerpt from the memoirs of a former tankman of the 24th Tank Regiment, which describes the duel of the new “four” "with a Soviet tank in the summer of 1942 near Voronezh.
“There were bloody street battles for Voronezh. Even by the evening of the second day, the valiant defenders of the city did not lay down their arms. Unexpectedly, Soviet tanks, which were the main force of defense, attempted to break through the ring of troops closed around the city. A fierce tank battle ensued." The author then quotes in detail
Sergeant Freyer's report: “On July 7, 1942, on my PzKpfw IV, armed with a long-barreled cannon, I took a position at a strategically important crossroads in Voronezh. Well disguised, we hid in a dense garden near one of the houses. A wooden fence hid our tank from the street side. We received orders to support the advance of our light combat vehicles with fire, protecting them from enemy tanks and anti-tank guns. At first everything was relatively calm, except for a few clashes with scattered groups of Russians, but nevertheless the battle in the city kept us in constant suspense.

It was a hot day, but after sunset it seemed to get even hotter. At about eight o'clock in the evening a Russian T-34 medium tank appeared to our left, clearly intending to cross the intersection we were guarding. Since the T-34 was followed by at least 30 other tanks, we could not allow such a maneuver. I had to open fire. At first, luck was on our side; with the first shots we managed to knock out three Russian tanks. But then our gunner, non-commissioned officer Fischer, radioed: “The gun is jammed!” Here it is necessary to explain that our front sight was completely new, and there were often problems with it, namely that after firing every second or third shell, the empty cartridge case got stuck in the breech. At this time, another Russian tank was fiercely pouring fire on the entire space around itself. Our loader, Corporal Groll, was seriously wounded in the head. We pulled him out of the tank and laid him on the ground, and the radio operator took the vacated loader’s place. The gunner extracted the spent cartridge case and resumed firing... Several more times, NCO Schmidt and I had to feverishly pick at the barrel with an artillery banner under enemy fire in order to pull out the stuck cartridges. The fire from Russian tanks smashed the wooden fence to pieces, but our tank still did not receive a single damage.

IN total we knocked out 11 enemy vehicles, and the Russians managed to break through only once, at the moment when our gun jammed again. Almost 20 minutes passed from the start of the battle before the enemy was able to open targeted fire on us from their guns. In the falling twilight, shell explosions and roaring flames gave the landscape some kind of eerie supernatural look... Apparently, it was from this flame that our people found us. They helped us get to the location of the regiment, stationed on the southern outskirts of Voronezh. I remember that, despite being tired, I could not sleep because of the sweltering heat and stuffiness... The next day, Colonel Rigel noted our merits in the order for the regiment:
"Fuhrer and Supreme Command sergeant of the 4th platoon Freyer is awarded the Knight's Cross. In the battle of Voronezh, Sergeant Freyer, commander of the PzKpfw IV tank, destroyed 9 medium Russian T-34 tanks and two light T-60 tanks. This happened at a time when a column of 30 Russian tanks was trying to break into the city center. Despite the overwhelming majority of the enemy, Sergeant Freyer remained faithful to his military duty and did not leave his post. He allowed the enemy to approach and opened fire on him from his tank. As a result, the Russian tank column was scattered and partially destroyed. Meanwhile, our infantry, after heavy bloody battles, managed to occupy the city.
In front of the entire regiment, I want to be the first to congratulate Sergeant Freyer on his high award. The entire 24th Tank Regiment is proud of our Knight's Cross and wishes him continued success in future battles. I would also like to take this opportunity to express special gratitude to the other members of the brave tank crew:
To gunner non-commissioned officer Fischer
Driver-mechanic non-commissioned officer Schmidt
Loading Corporal Groll
Radio operator Corporal Muller

and convey your admiration for their actions on July 7, 1942. Your feat will go down in the golden chronicle of the glory of our valiant regiment.”

The decision to create a medium tank with a short-barreled 75 mm gun was made in January 1934. Preference was given to the Krupp project, and in 1937 - 1938 it produced about 200 vehicles of modifications A, B, C and D.

These tanks had combat mass from 18 to 20 tons, armor up to 20 mm thick, speed on the highway no more than 40 km/h and cruising range on the highway 200 km. A 75-mm gun with a 23.5-caliber barrel length, coaxial with a machine gun, was installed in the turret.

During the attack on Poland on September 1, 1939, the German army had only 211 T-4 tanks. The tank showed itself well and was approved as the main one along with the T-3. Since December 1939, its mass production began (in 1940 - 280 pieces).

By the beginning of the campaign in France (May 10, 1940) in German tank divisions in the West there were only 278 T-4 tanks. The only result of the Polish and French campaigns was an increase in the thickness of the armor of the frontal part of the hull to 50 mm, side armor to 30 and turret to 50 mm. The weight reached 22 tons (modification F1, produced in 1941 - 1942). The width of the tracks was increased from 380 to 400 mm.

From the first days of the war, Soviet T-34 and KV tanks (see below) demonstrated the superiority of their weapons and armor over the T-4. Hitler's command demanded that their tank be re-equipped with a long-barreled gun. In March 1942, he received a 75 mm cannon with a 43-caliber barrel length (vehicle modification T-4F2).

In 1942, vehicles of the G modifications were produced, from 1943 - H and from March 1944 - J. The tanks of the last two modifications had 80 mm frontal hull armor and were armed with guns with a barrel length of 48 calibers. The weight increased to 25 tons, and the cross-country ability of the vehicles deteriorated noticeably. On modification J, the fuel supply was increased and the range increased to 300 km. Since 1943, 5-mm screens began to be installed on tanks, protecting the sides and turret (side and rear) from artillery shells and anti-tank rifle bullets.

The welded tank hull of a simple design did not have a rational slope of the armor plates. There were many hatches in the hull, which made access to units and mechanisms easier, but reduced the strength of the hull. Internal partitions divided it into three compartments. In front, in the control compartment, there were final drives, the driver (on the left) and the gunner-radio operator, who had his own surveillance devices, were located. The fighting compartment with a multifaceted turret housed three crew members: a commander, a gunner and a loader. The turret had hatches in the sides, which reduced its resistance to projectiles. The commander's cupola is equipped with five viewing devices with armored shutters. There were also viewing devices on both sides of the gun mantlet and in the side hatches of the turret. The rotation of the turret was carried out by an electric motor or manually, vertical aiming was carried out manually. The ammunition included high-explosive fragmentation and smoke grenades, armor-piercing, sub-caliber and cumulative shells. An armor-piercing projectile (mass 6.8 kg, initial speed - 790 m/s) penetrated armor up to 95 mm thick, and a sub-caliber projectile (4.1 kg, 990 m/s) - about 110 mm at a distance of 1000 m (data for a gun in 48 calibers).

A 12-cylinder water-cooled Maybach carburetor engine was installed in the engine compartment at the rear of the hull.

The T-4 turned out to be a reliable and easy-to-control vehicle (it was the Wehrmacht's most popular tank), but poor maneuverability, a weak gasoline engine (the tanks burned like matches) and undifferentiated armor were disadvantages over Soviet tanks.
