Characteristics turrets of the tank Pz.IV Ausf.J.

The given production data for the Pz.IV, unfortunately, cannot be considered absolutely accurate. AT 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. It is enough to 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 modifications, 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 in significantly large quantities, than other German tanks, was exported. Judging by German statistics, 490 combat vehicles were delivered to the allies of Germany, as well as to Turkey and Spain in 1942-1944.

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

In October 1942, the first 11 Pz.IV Ausf.G arrived in Romania. Later, in 1943-1944, the Romanians received another 131 tanks of this type. They were used in hostilities both against the Red Army and against the Wehrmacht, after the transition of Romania 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 took Active participation in battles with German troops, being the main strike force 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 beginning of the 60s. At the same time, the regular MG 34 machine guns were removed from the tanks, and Soviet diesel engines were installed instead.

PRODUCTION OF TANKS Panzer IV

DESIGN DESCRIPTION

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

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

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

In the engine compartment, in the aft part of the tank, were the engine and all its systems, as well as auxiliary engine turret slewing mechanism.

FRAME the tank was welded from rolled armor plates with surface carburizing, mostly located at right angles to each other.

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

Pz.IV Ausf.F1. Manhole covers (driver and machine gunner) with round hatches for launching signal rockets are clearly visible. A semi-cylinder welded to the side of the hull closes the exhaust port of the brake cooling system before storing the spare rollers.

In the frontal hull sheet on the left was the driver’s viewing device, which included a triplex glass block closed by a massive armored sliding or folding shutter Sehklappe 30 or 50 (depending on the thickness of the frontal armor), and a KFF 2 binocular periscope observation device (for Ausf. A-KFF 1). The latter, if 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 closed by folding armored covers.

Between the stern of the hull and the fighting compartment was a partition. In the roof of the engine compartment there were two hatches 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 to the radiator, and in the reverse bevel of the starboard side there was an air outlet from the fans.

The layout of the tank Pz.IV:

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

Armor scheme for a medium tank Pz.IV.

TOWER- welded, hexagonal, mounted on a ball bearing on the turret hull sheet. In its front part, in a 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 shutters from inside the tower. Starting with modification G, the hatch to the right of the gun was missing.

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

Aft part of the turret modification Ausf.E.

In the rear part of the roof of the tower was a commander's cupola with five viewing slots with triplex glass. Outside, the viewing slots were closed with sliding armored shutters, and the hatch in the roof of the turret, designed for the entry and exit of the tank commander, was a double-leaf lid (later a single-leaf). The turret had a dial-hour type device for determining the location of the target. The second such device was at the disposal of the gunner and, having received an order, he could quickly turn the turret on 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 along wooded area and settlements).

For boarding and disembarking crew members on the sides of the tower there were hatches with single-leaf and double-leaf (starting with the F1 variant) covers. Viewing devices were installed in the manhole covers and sides of the tower. The aft sheet of the tower was equipped with two hatches for firing personal weapons. On some machines of modifications H and J, in connection with the installation of screens, viewing devices and hatches were absent.

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 gun of 75 mm caliber from Rheinmetall-Borsig. The length of the gun barrel is 24 calibers (1765.3 mm). Gun weight - 490 kg. Vertical aiming - in the range from -10 ° to + 20 °. The gun had a vertical wedge gate and electric trigger. Its ammunition included shots with smoke (weight 6.21 kg, muzzle velocity 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.

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

Return of the course machine gun

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

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

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

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

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

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

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

Diagram showing the internal structure of the tank

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

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

Serial Pz.Kpfw.IV Ausf.D, spring 1940

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

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

Mounting a large number of spare tracks was a very common occurrence.

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

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

Based on the experience of the first two campaigns

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

Broken turrets were a fairly common occurrence for the Pz.Kpfw.IV Ausf.D. France, May 1940

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

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

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

Pz.Kpfw.IV Ausf.D, issued in April 1940, with shielding of the turret box, and at the same time additional armor of the frontal hull plate

It became clear after Polish campaign September 1939. The fact is that Polish troops massively used 37-mm anti-tank guns Armata przeciwpancerna 37 mm wz against German tanks. 36 Bofors. Even though the Polish shells were not the most best quality, they confidently punched german cars in all projections. The strengthening of the frontal part up to 30 mm did not help much here either.

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

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

Pz.Kpfw.IV Ausf.E from the 20th Panzer Division, summer 1941

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

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

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

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

As you can see, not all Pz.Kpfw.IV Ausf.E received screens

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

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

Pz.Kpfw.IV Ausf.D with additional Vorpanzer armor, 1942

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

For crossings and other purposes

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

Brückenleger IV b, in the spring of 1940 a series of 16 of these vehicles was produced

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

Brückenleger IV c from the 39th tank engineer battalion, 1941

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

This is what Pz.Kpfw.IV Ausf.E 81005 and 81006 looked like with a new chassis

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

Tauchpanzer IV from the 18th Panzer Division

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

Blitzkrieg support vehicle

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

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

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

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

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

The result of the meeting of the Pz.Kpfw.IV with the KV-2, summer 1941

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

The German tank crews could quite rightly blame the 6th department of the Armaments Directorate for such significant losses, which approached the issue of strengthening the armor very lightly. In fact, the shielding installed on the tanks corresponded to the experience of the September 1939 campaign. At the same time, the fact that the French already had 47-mm tank and anti-tank guns was ignored. And this was done in vain: even a 47-mm SA 35 tank gun with a barrel length of 32 caliber, as shown by tests in the USSR, could easily penetrate 50 mm armor of German tanks at a distance of 400 meters.

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

Captured Pz.Kpfw.IV Ausf.E from the 20th Panzer Division, NIIBT Polygon, August 1941

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

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

The same car in front. Hits and a split screen are visible in the area of ​​\u200b\u200bthe driver's viewing device

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

.“Armor protection tank T-IV hit by artillery of all calibers.

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

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

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

Unlike the StuG III, the frontal armor of the captured Pz.Kpfw.IV Ausf.E was quite tough for a 45mm shell.

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

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

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

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

One of the Pz.Kpfw.IV Ausf.Ds re-armed with the 7.5 cm KwK 40 cannon and fitted with side screens

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

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

Attempts to improve the protection of the tank led to the appearance at the end of 1942 modification "Ausfuhrung G". The designers knew that the mass limit that the undercarriage could withstand had already been chosen, so they had to make a compromise solution - to dismantle the 20-mm side screens that were installed on all "fours", starting with the "E" model, while simultaneously increasing the base armor of the hull to 30 mm, and due to the saved mass, install overhead screens 30 mm thick in the frontal part.

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

By the end serial production tanks PzKpfw IV "Ausfuhrung G" their regular main weapon was a 75-mm gun with a barrel length of 48 calibers, the commander's cupola hatch became single-leaf. Late production PzKpfw IV Ausf.G tanks are outwardly almost identical to the early Ausf.N. From May 1942 to June 1943, 1,687 Ausf.G tanks were manufactured, an impressive number, given that in five years, from the end of 1937 to the summer of 1942, 1,300 PzKpfw IVs of all modifications (Ausf.A -F2), chassis no. - 82701-84400.

In 1944 was made tank PzKpfw IV Ausf.G with hydrostatic drive wheels. The design of the drive was developed by specialists from the firm "Zanradfabrik" in Augsburg. The Maybach's main engine drove two oil pumps, which, in turn, activated two hydraulic motors connected by output shafts to the drive wheels. All power point located in the aft part of the hull, respectively, and the drive wheels had a rear, and not the front, usual for the PzKpfw IV. The speed of the tank was controlled by the driver, controlling the oil pressure created by the pumps.

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

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

The installation of a long-barreled 75 mm gun proved to be a rather controversial measure. The cannon led to an excessive overload of the front of the tank, the front springs were under constant pressure, the tank acquired a tendency to swing even when moving on a flat surface. It was possible to get rid of the unpleasant effect on the modification "Ausfuhrung H", put into production in March 1943.

On tanks of this model, the integral armor of the frontal part of the hull, superstructure and turret was reinforced up to 80 mm. The PzKpfw IV Ausf.H tank weighed 26 tons, and even despite the use of the new SSG-77 transmission, its characteristics turned out to be lower than those of the "fours" of previous models, so the speed of movement over rough terrain decreased by at least 15 km, and the specific pressure on the ground, the acceleration characteristics of the machine fell. A hydrostatic transmission was tested on the PzKpfw IV Ausf.H experimental tank, but tanks with such a transmission did not go into mass production.

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

The Ausf.H tanks were the first "fours" to use zimmerite anti-magnetic coating; only the vertical surfaces of the tank were supposed to be covered with zimmerite, however, in practice, the coating was applied to all surfaces that an infantryman standing on the ground could reach, on the other hand, there were also tanks on which only the forehead of the hull and superstructure was covered with zimmerite. Zimmerite was applied both in factories and in the field.

The tanks of the Ausf.H modification became the most massive among all PzKpfw IV models, 3774 of them were built, production was discontinued in the summer of 1944. Chassis serial numbers are 84401-89600, some of these chassis served as the basis for the construction of assault guns.

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

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

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

An attempt to somewhat reduce the mass of the tank was the installation of welded wire anti-cumulative screens; such screens were called "Thoma screens", after the name of General Tom). Such screens were placed only on the sides of the hull, and the former screens made of sheet steel remained on the towers. On tanks of late production, instead of four rollers, three were installed, and vehicles with steel track rollers without rubber were also produced.

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

The production of PzKpfw IV Ausf.J tanks ceased in March 1945, with a total of 1,758 vehicles built.

By 1944, it became clear that the design of the tank had exhausted all reserves for modernization, a revolutionary attempt to increase the combat effectiveness of the PzKpfw IV by installing a turret from the Panther tank, armed with a 75-mm gun with a barrel length of 70 calibers, was unsuccessful - the undercarriage was too overloaded. Before proceeding with the installation of the Panther turret, the designers tried to squeeze the gun from the Panther into the turret tank PzKpfw IV. The installation of a wooden model of the gun showed the complete impossibility of the crew members working in the turret due to the tightness created by the breech of the gun. As a result of this failure, the idea was born to mount the entire turret from the Panther on the Pz.IV hull.

Due to the constant modernization of tanks in the course of factory repairs, it is not possible to determine with accuracy how many tanks of one or another modification were built. Very often there were various hybrid variants, for example, turrets from Ausf.G were placed on the hulls of the Ausf.D model.

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. 4 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.

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.

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. First Battalion tank regiment got 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 by the 6th SS Panzer Army in the area of ​​Lake Balaton in January - March 1945, which ended in- scrap. During January 1945 alone, 287 Pz. IV, of which revolt - renovated and returned to service May 53- tires.

Pz. IV took part in hostilities until the last days of the 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 issued self-propelled artillery installations, 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.

The decision to develop a medium tank (also called an artillery support tank) with a short-barreled gun was made in January 1934. The following year, Krupp-Gruson, MAN and Rheinmetall-Borsig presented their prototypes for testing. The army team liked the Krupp project. Modification A machines were produced in 1937, modifications B (the so-called installation batches) - in 1938. During next year built 134 tanks of modification S.

Combat weight of tanks 18.4 - 19 tons, armor thickness up to 30 millimeters, maximum speed on the highway - 40 km / h, cruising range - 200 kilometers. The turret was equipped with a 75 mm long L / 24 gun (24 caliber) and a coaxial machine gun. Another one was located on the right in the frontal sheet of the hull in a ball mount. In terms of design and layout, the tank basically repeated the medium Pz Kpfw III.

As of September 1, 1939, the Wehrmacht had 211 Pz Kpfw IV tanks. The tank proved to be excellent during the Polish campaign, and along with the Pz Kpfw III medium tank, it was approved as the main one. Its mass production began in October of the same year. Already in the 40th year, 278 pieces were produced. modifications D and E.

AT tank divisions In Germany, at the time of the French invasion, there were about 280 Pz Kpfw IV tanks in the Western Theater. Operation in combat conditions has shown that the armor protection is insufficient. As a result, the thickness of the sheets of the frontal part was increased to 60 mm, the sides - up to 40 mm, the turret - up to 50 mm. As a result, the combat weight of modifications E and F, which were produced in 40-41, increased to 22 tons. To keep the specific pressure within acceptable limits, the width of the tracks was slightly increased - up to 400 millimeters from 380.

The German “fours” lost firefights with Soviet-made KB and T-34 tanks due to inadequate weapon characteristics. Starting in the spring of 1942, 75-mm long-barreled guns (L / 43) began to be installed on the Pz Kpfw IV. The initial speed of the sub-caliber projectile was 920 meters per second. This is how the Sd Kfz 161/1 (modification F2) appeared, which surpassed even the T-34-76 in armament. Modification G was produced in 1942-1943, H - from 43rd and J - from June 44th (all modifications were coded as Sd Kfz 161/2). The last two modifications were the most perfect. The thickness of the frontal armor plates was increased to 80 millimeters. The power of the gun increased: the barrel length was 48 calibers. Weight increased to 25 thousand kg. Ausf J at one gas station could move along the highway for a distance of up to 320 kilometers. Since 1943, 5-millimeter screens have become mandatory on all tanks, which protected the sides and the turret behind and on the side from bullets from anti-tank rifles and cumulative projectiles.

The welded hull of the tank was simple in design, although it did not differ in the rational slope of the armor plates. A large number of hatches facilitated access to various mechanisms and assemblies, but at the same time reduced the strength of the hull. Partitions divided the interior into three compartments. The control compartment occupied the front compartment, which housed the gearboxes: onboard and general. The driver and radio operator were located in the same compartment, both had their own observation devices. The multifaceted turret and the middle compartment were assigned to the fighting compartment. The main armament, ammunition rack and other crew members: loader, gunner and commander were located in it. Ventilation was improved by hatches on the sides of the turret, but they reduced the projectile resistance of the tank.

The commander's cupola had five viewing devices with armored shutters. There were also viewing slots in the side hatches of the tower and on both sides of the gun mantlet. The gunner had a telescopic sight. The tower rotated manually or with the help of an electric motor, the vertical aiming of the gun was carried out only manually. The ammunition included smoke and high-explosive fragmentation grenades, cumulative, sub-caliber and armor-piercing shells.

In the engine compartment (stern of the hull) housed a 12-cylinder water-cooled carburetor engine. AT undercarriage included eight rubber-coated road wheels of small diameter, which were interlocked in two. Leaf springs were elastic suspension elements.

The medium tank Pz Kpfw IV proved to be an easy-to-handle and reliable vehicle. However, its cross-country ability, especially for the overweight tanks of the latest releases, was rather poor.
