The first Pz tanks. 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 village- 116 tanks, and the company Krupp almost you - completed it by transferring 113 vehicles to the troops. The first "combat" operations involving- eat Pz. IV became the Anschluss of Austria and the seizure 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 1 September- In 1939, the Wehrmacht had 211 tanks Pz. 4 modifications A, B and C. According to the then existing staff, a tank division should have consisted of 24 tanks Pz. IV, 12 vehicles in each regiment. One- but only the 1st and 2nd tank regiments of the 1st tank were fully staffed- howl division (1. Panzer Division). The Training Tank Battalion also had a full staff(Panzer Lehr Abteilung), attached 3rd tan- war division. In the remaining formations there were only a few Pz. IV, which - they were superior in armament and armor protection to all types of those opposing them Polish tanks. However, over time- During the Polish campaign, the Germans lost 76 tanks of this type, 19 of them irretrievably.

To the beginning of the French Pan campaign- cervaffe already had 290 Pz. IV and 20 bridge laying machines at their base. Like Pz. lll they were concentrated in divisions operating in the directions of the main attacks. General Rommel's 7th Panzer Division, for example, had 36 Pz. IV. During the battles, the French and English- we managed to knock out 97 tanks Pz. IV. Without - The return losses of the Germans amounted to only 30 combat vehicles of this type.

In 1940 specific gravity tanks Pz. IV in Wehrmacht tank formations increased slightly. On the one hand, thanks to the growth of production, and on the other, due to the decrease- reducing the number of tanks in the division to 258 units. During a short-lived operation in the Balkans in the spring of 1941. Pz. IV, participation - who fought in battles with the Yugoslav, Greek- mi and British troops, no losses- carried

To the beginning of Operation Barbarossa Ver- Macht had 439 tanks Pz. IV, by the end of 1941, 348 of them were lost without recovery- military. Pz. IV, armed short-barreled- guns, could not effectively- rummage with Soviet medium and heavy- mi tanks. Only with the advent of the long-barreled modification did the situation level out. By mid-1943 Pz. IV became the main German tank on Vos- exact front. The staff of the German tank division included a tank regiment of two battalions. In the first battalion, two companies armed themselves Pz. IV, in the second, only one company. Overall, the race division- I thought there were 51 tanks Pz. IV combat battalions - nah. In Operation Citadel they made up- or almost 60% of the tanks that took part- ity in combat.

In North Africa, up to the capital- lation of German troops, Pz. IV successfully resisted all types of Union tanks- nicknames Best of luck these tanks achieved in the fight against the British- Ser tanks A.9 and A. 10 - mobile- new, but lightly armored. First modification cars F 2 was delivered to

North Africa in the summer of 1942. At the end of July, Rommel's Afrika Korps raced- I thought there were only 13 tanks Pz. IV, of which 9 were F 2. In English documents of that period they were called Panzer IV Special.

Despite the defeat at El Alamein, the Germans began to reorganize- tion of their forces in Africa. On December 9, 1942, the 5th Tank Army was formed in Tunisia, which included- sneeze entered transferred from France

The 10th Panzer Division, which had- weapons of tanks Pz. IV Ausf. G. These tanks took part in the defeat American troops at Kasserine on February 14, 1943, however, this was the last successful operation- German radio on the African continent- those - already on February 23 they were forced- We went on the defensive, their forces were quickly melting away. On May 1, 1943 in German troops- kakh in Tunisia there were only 58 tanks - of which 17 Pz. IV.

In 1944, the organization of the German tank- howl division has undergone significant changes. The first battalion of the tank regiment received tanks Pz. V "Panther", second - the swarm was complete Pz. IV. In fact, the "panthers" entered military service- not everyone's life tank divisions Wehrmach- ta. In a number of formations, both battalions had only Pz. IV.

In the summer of 1944, German troops- whether defeat after defeat, as in Za- pada, and in the East. I comply- There were also significant losses: in only two months- Syatsa - August and September - 1139 tanks were destroyed Pz. IV. However, me - no, their number in the troops continued to increase- to be significant. In November 1944 Pz. IV accounted for 40% of German tanks on the Eastern Front, 52% in 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 failure- scrap. During January 1945 alone, 287 were shot down. Pz. IV, from them rose - refurbished and returned to service 53 ma- tires.

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

major tank losses Pz. IV amounted to 7636 units.

Pz. IV in significantly larger quantities- wow, than other German tanks, having delivered- was intended for export. Judging by the German hundred- tistics, Germany's allies, as well as Turkey and Spain arrived in 1942 - 1944. 490 combat vehicles. Besides Ger- Pz mania. IV were in service in Hungary (74, according to other sources - 104), Romania (142), Bulgaria (97), Fin- Land (14) and Croatia.

Based on Pz. IV were produced self-propelled artillery installations, commander- such tanks, advanced artillery vehicles- Riy 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- was in service with the Czechoslovak army until the early 1950s. Except for Czechoslovakia in the post-war years Pz. IV were used in the armies of Spain, Turkey, France, Finland, Bulgaria and Syria.

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 initial speed projectile 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 performance characteristics Pz.IV did not change (except for the thickness of the armor) and during two years of the war 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 security, which led to their overweight and deterioration 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 en masse cumulative ammunition was rarely used, but 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 new type medium tank - "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 required replacing the turret, it would still cost more lightweight design than "Panther". 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 as much as 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", which would be delivered to the soldiers of the anti-Hitler coalition much more trouble than the Panthers.

Production of this tank, created by Krupp, began in 1937 and continued throughout the Second World War.
Like the T-III tank (Pz.III), power point located at the rear, and the power transmission and drive wheels at the front. The control compartment housed the driver and gunner-radio operator, firing from a machine gun mounted in a ball joint. Combat compartment was located in the middle of the body. A multifaceted welded turret was mounted here, which housed three crew members and installed weapons.

T-IV tanks were produced with the following weapons:

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

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

Tank PzKpfw IV. History of creation.

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

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

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

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

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

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

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

Description of the PzKpfw IV tank

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

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

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

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

Power point.

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

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

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

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

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

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

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

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