German anti-tank gun pack 40. Anti-tank guns. Weight in combat readiness, kg

7.5 cm Kw.K.40 / 7.5 cm Stu.K.40- a family of German 75-mm tank (KwK 40) and assault guns (StuK 40), based on the 75-mm PaK 40 (PaK 44 L / 46) field anti-tank gun. Samo PaK gun 40 appeared in the game later than the KwK 40, and in terms of its game characteristics, before patch 1.49, it was a complete copy of the long-barreled version of the KwK 40 L/48 / StuK 40 L/48.

History reference

The most massive tank gun of the Wehrmacht. It was created by the Krupp and Rheinmetall design bureaus on the basis of the 75 mm PaK 40 anti-tank gun, to replace the KwK37. Produced from 1941 to 1945. The gun received an electric ignition device and a semi-automatic wedge gate. The length of the shells and the breech of the gun also had to be reduced, which resulted in a slight drop in the initial velocity of the projectile compared to the PaK 40. The gun was produced in several modifications, mainly differing in different barrel lengths and some mechanisms depending on the target vehicle. Guns mounted on tank destroyers received the name StuK40, and on tanks - KwK 40.

By the beginning of Operation Barbarossa, Germany had not a large number of anti-tank PaK guns 40, which was due to the weak armor of enemy tanks. But in battles with the latest Soviet T-34s and heavy KV-1 tanks, most of the other Wehrmacht guns proved to be ineffective. The tank commission headed by Guderian decided to develop a long-barreled gun based on PaK 40 for installation on tanks and self-propelled units. The development of the gun was carried out by two firms: the design bureau Krupp was responsible for the ballistics of the gun, and Rheinmetall was responsible for its design. Since PaK 40 was very heavy gun, then the development of a lightweight version for installation on tanks took long time and entailed a slight deterioration in the shooting characteristics of the gun. The recoil distance of the original PaK 40 (~900 mm) and the length of the shells (969 mm) were too long for the cramped tank house. Therefore, the designers had to reduce the recoil distance of the gun (up to ~ 520 mm) and shorten the length of the shells (up to ~ 495 mm), and in order to maintain a comparable amount of propellant explosive, the diameter of the shells had to be increased. At the same time, the gun barrel remained unchanged, the same as on the PaK 40 L/46, with a length of 2470.5 mm. The barrel had progressive rifling in increments of 6° to 9°. The result was the initial version of the KwK 40 L / 43 gun with a 43 caliber (3225 mm) barrel. Reducing the breech of the gun freed up space for additional ammunition, and a shortened charging chamber with a large diameter simplified loading and increased the rate of fire.

Due to the large amount of propellant explosive in the projectiles used, the gun had problems, especially with its first versions. Often, after a shot, the cartridge case got stuck in the breech of the gun, blocking the ability to reload the gun or fire from it. To remove the cartridge case, the crew had to get out of the tank and push the cartridge case out of the gun through the barrel with a ramrod. This took considerable time, and in combat conditions it put the crew in danger. To solve this problem, it was necessary to reduce the amount of explosive in the propellant charge and change the design of the muzzle brake. As a result, there was little difference between previously produced shells and guns and their later versions.

By the spring of 1942, the original version was ready for installation on Pz.Kpfw tanks. IV. And already the first use of Pz.Kpfw. IV Ausf. F2 showed the undeniable superiority of the new gun over the guns of the enemy, allowing you to destroy enemy tanks at such distances at which the enemy was simply not able to inflict significant damage. With the advent of the enemy guns of larger caliber, this advantage came to naught. Nevertheless, various modifications of the PaK 40 remained quite effective until the very end of the war.

KwK40 L/43 (75 mm)

The original version of the German 75 mm KwK 40 cannon with a barrel length of 43 calibers (3225 mm). The gun did an excellent job both with the latest Soviet T-34 tanks, and with heavy KV-1 and KV-2 tanks. From April 1942 to June 1943 it was installed on Panzer IV medium tanks. In the version for Pz.Kpfw. IV Ausf. The F2 had a single-chamber ball-shaped muzzle brake, while the later versions had a two-chamber muzzle brake.

Gun ballistics provides high precision projectile hits, which allows you to target modules or vulnerabilities in the enemy’s armor. The armor penetration of a chamber shell is sufficient to penetrate the frontal armor of most medium tanks, but may not be enough to penetrate the front projection of the turret of late medium tanks. Entry-level heavy tanks can be dealt with with a sub-caliber projectile. The most effective tactic against armored targets would be to flank and attack the side of the hull or turret. Vertical angles aiming allows you to target enemies from hills and other uneven surfaces, but it will not work to full use. Due to the low armor effect of all 75-mm shells, only the chamber PzGr.39 and the sub-caliber PzGr.40 will be really useful. The HEAT projectile Gr.38 HL/B has insufficient armor penetration and poor ballistics, while the high-explosive fragmentation Sprgr.34 will only be effective against unarmored vehicles.

Although the gun slightly surpasses the comparable guns of the USSR and the USA in terms of armor penetration of the main projectile, it is inferior to them in the armor impact of shells. Which may require several hits to destroy the enemy. It follows that in order to successfully destroy the enemy, you need to fire the first shot and, if possible, hit vulnerable spot, destroying or depriving the enemy tank of the ability to shoot back.

History reference

The KwK40 L/43 gun became the most massive tank gun (including other modifications). The gun made it possible to destroy all tanks of that time (1942-1943) at a distance of about 1500 meters. It was installed on new modifications of the Panzer IV tank, which led to its mass character. Since it was an intermediate modification, its production was soon stopped in favor of a long-barreled version. Tanks with this gun participated in the battles until the very end of the war and found well-deserved fame among the Wehrmacht tankers and their allies. But with the advent of more powerful weapons and new armored tanks at the enemy, KwK40 L / 43 could no longer hit the enemy so confidently.

For the first time tanks Pz.Kpfw. IV Ausf. F2s with the new 75mm KwK40 L/43 cannon were used by Rommel during Operation Venice in Libya in May 1942 against the British 8th Army. The front-line units received only a few new tanks, and even then with a delay to the start of the operation, which were nicknamed "special" by the soldiers. At the same time, the newest "pilot" Grant tank in the amount of 138 units entered the 8th Army for testing. German intelligence then mistakenly believed that “pilot” was the name of the new British tank. From the August reports of the German Afrika Korps, it became clear that the new "Special" tank easily destroyed any enemy tank from a distance of 1500 meters or more, including the "Pilot". Tests have shown that main problem The guns had a muzzle brake. Due to its design, the shot produced a bright flash of flame and a noticeable puff of smoke, unmasking the position. In subsequent versions of the gun, the design of the muzzle brake was changed.

KwK40 L/48 (75 mm)

Long-barreled variant of the 75 mm KwK 40 gun with a 48 caliber (3600 mm) barrel length. An increase in the barrel length offset the drop in the muzzle velocity of the projectile compared to the PaK 40, which slightly increased the armor penetration of the projectiles and the accuracy of fire. This version of the gun became the most widespread and was installed on Panzer IV tanks from March 1943 to April 1945, allowing them to destroy enemy tanks of comparable class at distances of 1000-1500 m, remaining out of reach of enemy guns. But with the advent of more powerful guns from the Allies, this advantage came to naught.

In the game, the weapon is present on:

• For all 3774 pcs. Pz.Kpfw. IV Ausf. H
• For all 1758 pcs. Pz.Kpfw. IV Ausf. J
• For all 105 pcs. Panzerbefehlswagen IV converted from Pz.Kpfw. IV Ausf. J (17 units) and restored Panzer IVs (88 units)
• On the captured tanks Panzerkampfwagen KV-1B 756(r)

The ballistics of the gun ensures high accuracy of projectile hits, which allows you to target modules or vulnerabilities in the enemy’s armor. The armor penetration of a chamber shell is sufficient to penetrate the frontal armor of most medium tanks, but may not be enough to penetrate the front projection of the turret of late medium tanks. Entry-level heavy tanks can be dealt with with a sub-caliber projectile. The most effective tactic against armored targets would be to fly from the flag and attack the side of the tank or turret. Good elevation angles allow you to attack enemies from hills and other uneven surfaces. Due to the low armor effect of all 75-mm shells, only the chamber PzGr.39 and the sub-caliber PzGr.40 will be really useful. The HEAT projectile Gr.38 HL/B has insufficient armor penetration and ballistics, while the high-explosive fragmentation Sprgr. 34 will only be useful against unarmored vehicles.

Although the gun slightly surpasses the comparable guns of the USSR and the USA in terms of armor penetration of the main projectile, it is inferior to them in the armor impact of shells. Which may require several hits to destroy the enemy. It follows that in order to successfully destroy the enemy, you need to make the first shot and, if possible, hit the weak spot, destroying the enemy tank or depriving him of the ability to shoot.

But with the advent of more powerful guns and new armored tanks from the enemy, the KwK40 L / 48 could no longer hit the enemy so confidently. After the war, the surviving tanks with this gun were in service with the USSR until the end of 1949. And in 1967, several tanks took part in the Six Day War.

Advantages and disadvantages

The gun is well suited to destroy most medium and some heavy tanks at a distance of up to 1000 m. Although it can hit a target at a distance of 1500 m, due to the low armor penetration of shells at such a distance, it will not be able to penetrate the armor of most tanks.

Advantages:

• High rate of fire
• Ability to hit medium tanks at a distance of 1000 m
• Comfortable elevation angles

Flaws:

• Weak armor action of shells
• Low armor penetration makes it easy to destroy heavy tanks at medium and long distances

StuK40 L/43 (75mm)

The original version of the German assault 75 mm StuK 40 gun with a barrel length of 43 calibers (3225 mm). The StuK 37 L/24 assault gun proved to be excellent both against enemy infantry and against the new Soviet T-34 tanks. But the troops needed a weapon capable of dealing with enemy tanks at a long distance. Despite the fact that Krupp had already developed and tested a prototype of the 7.5 cm Kanone L / 40 gun, in November 1941 the command ordered all work to be curtailed. Adolf Hitler demanded that assault tanks be equipped with a long-barreled 75-mm cannon with a high muzzle velocity, capable of fighting heavy KV tanks at long distances. Based on his requirements, the command ordered the development of such a weapon from Rheinmetall, which produced field anti-tank gun PaK 40, which has already proven itself in the field. Since the PaK 40 was a very heavy gun, the development of a lighter version for mounting on assault tanks took a long time and resulted in a slight deterioration in the shooting characteristics of the gun. The recoil distance of the original PaK 40 (~900 mm) and the length of the projectiles (969 mm) were too long for the cramped cabin. Therefore, the designers had to reduce the recoil distance of the gun and shorten the length of the shells. At the same time, the gun barrel remained unchanged, the same as on the PaK 40 L/46, with a length of 2470.5 mm. The barrel had progressive rifling in increments of 6° to 9°. The result was a StuK 40 L / 43 gun, 43 calibers long (3225 mm). Reducing the breech of the gun freed up space for additional ammunition, and a shortened charging chamber with a large diameter simplified loading and increased the rate of fire. The gun received an electric ignition device, a semi-automatic wedge gate and a cylindrical two-chamber muzzle brake, damping up to 58% of the recoil. The gun was mounted on a solid frame along with guidance devices. Which provided vertical pointing angles of -6° ~ +20° and horizontal -12° ~ +12°. The gun coped well with both the latest Soviet T-34 tanks and heavy KV-1 and KV-2 tanks. The first three guns were ready in February of 1942, although mass production began in April. And the first units to receive Stug III F assault tanks with a new gun were the Great Germany division and the 1st tank division SS Leibstandarte SS Adolf Hitler.

In the game, the weapon is present on:

The first units to receive Stug III F assault tanks with the new gun in early 1942 were the Grossdeutschland division and the 1st SS Panzer Division Leibstandarte SS Adolf Hitler. Soon they took part in the summer offensive German troops. And although the gun made it possible to easily destroy any enemy tank from a distance of 1000 meters or more, the limited aiming angles did not allow effective offensive operations. At the same time, vehicles with this gun proved to be excellent in defense, and in fact moved from the class of assault guns to tank destroyers.

By the beginning of Operation Citadel, more than 700 StuG long-barreled assault guns were in service. And although the operation failed, StuG III proved to be very successful. So, according to the countdown of the 11th Assault Gun Division for August 1943, they managed to destroy 423 enemy tanks, irretrievably losing only 18 assault guns. The September command report stated that the gun could easily hit any Soviet tank below the tiger class. It was noted that soviet tanks often panicked when fighting German assault tank destroyers. And from the orders intercepted by intelligence, it followed that Soviet tankers were forbidden to engage in battle with German assault guns.

The production of guns and tanks continued until the very end of the war. And in 1967 several assault tanks took part in the Six Day War.

Available projectiles

The KwK 40 / StuK 40 gun from PaK 40 inherited a whole family of 75 mm ammunition. While the shells remained unchanged, the cartridge case had to be reduced in length and increased in diameter. As a result, the amount of propellant charge in the cartridge case became less than in PaK 40, which led to a slight deterioration in ballistics and armor penetration of shells for the new gun. And due to the fact that there was still quite a lot of propellant charge in the sleeve, after the shot, the sleeve sometimes got stuck in the breech of the gun, jamming it. This forced the crew to leave the car and push the cartridge case manually through the gun barrel with a ramrod. This problem was solved by reducing the explosive in the propellant charge and changing the muzzle brake. Therefore, shells produced in different time have different characteristics.

The armor-piercing projectile had a thick steel body, inside which was placed an explosive charge, a bottom fuse and a tracer. He could penetrate armor plates of considerable thickness and hit the internal elements of the tank with an explosion.

The sub-caliber projectile was made of solid metals(usually made of tungsten carbide or hard steels) armor-piercing core, which was fixed on a pallet in the projectile body. Such a projectile was lighter than a conventional armor-piercing projectile and had a higher muzzle velocity. Due to this, its armor-piercing ability was also higher, since only one core pierced the armor.

A cumulative projectile could penetrate armor due to the fact that waves of gases formed during the explosion were concentrated at the point where the projectile met the armor. Its armor-piercing ability did not depend on the firing range, however, its damaging effect inside the tank was smaller than other anti-tank shells. To prevent the body of the projectile from being destroyed before the explosive charge worked, it was necessary to reduce the speed of the projectile at the moment it hit the surface of the armor. In addition, the penetrating power of the HEAT projectile dropped significantly due to the rotation of the projectile in flight, to reduce which it was necessary to reduce the muzzle velocity of the projectile. As a result, the firing range of HEAT projectiles did not exceed 1500-2000 m. To prevent the body of the projectile from being destroyed before the explosive charge worked, it was necessary to reduce the speed of the projectile at the moment it hit the surface of the armor. In addition, the penetrating power of the HEAT projectile dropped significantly due to the rotation of the projectile in flight, to reduce which it was necessary to reduce the muzzle velocity of the projectile. As a result, the firing range of cumulative projectiles did not exceed 1500-2000 m.

High-explosive fragmentation projectile equipped with a head fuse of instant and inertial action with a deceleration setting. Used to engage infantry and lightly armored targets.

The smoke projectile was filled with a smoke-forming composition and supplied with an impact fuse. The smoke cloud was small, about 30 m in diameter, and lasted about 30 seconds. These shells were very rarely used by tanks.

German 75-mm armor-piercing tracer chamber projectile with armor-piercing and ballistic tip model 1939 - 7.5 cm. Panzergranate 39. The most common German armor-piercing projectile, produced in various modifications for guns ranging in caliber from 20 mm to 128 mm. With the exception of the caliber, the differences were minimal, mainly in the quality of the steel and the number of guide rings. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge. Cartridges with a propellant charge differed in length and diameter depending on the design of the breech of the gun (even in guns of the same caliber).

The sleeve with a length of 495 mm contained 2.15 kg of smokeless powder, a dibasic mixture of nitrocellulose and diethylene glycol dinitrate, as the main propellant charge. The propelling charge is made in the form of pressed cylindrical tubes 370 mm and 420 mm long, placed in a rayon bag. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St. and a subversive charge weighing 0.315 kg, initiating the detonation of the main propellant charge.

The projectile consists of a steel body, in the head part of which there is a soft armor-piercing tip covered with a ballistic cap. The armor-piercing tip is attached to the head of the projectile by soldering with fusible solder. In the lower part of the projectile there was a chamber with 0.017 kg of explosive (phlegmatized RDX) and a Bdz 5103* detonator combined with a tracer. The projectile received rotation due to the friction of the copper guide ring on the rifled barrel of the gun. When fired, a tracer ignited, allowing you to track the flight of the projectile. The ballistic cap provided a high speed of the projectile over a long distance. The soft armor-piercing tip took over kinetic energy collision of the projectile with the armor, thereby protecting it from destruction and breaking the integrity of the armor, making it easier for the main projectile. At high angles of attack, the armor-piercing tip also ensured the normalization of the projectile. The sharp-headed steel projectile, crushing the soft armor-piercing tip, crashed into the weakened armor and pierced it, forming a cloud of armor fragments. Cocked on impact, the gas-dynamically retarded bottom detonator detonated the explosive charge when the projectile had already pierced the armor and flew some distance away from it.

There was a training version of the PzGr. 39 Ub.

Verdict
The main armor-piercing projectile. High muzzle velocity provides good ballistics and armor penetration of the projectile. The amount of explosive, although small, allows you to inflict additional damage to the crew and flammable modules. With the help of a tracer, you can track the trajectory of the projectile and more accurately adjust the sight, but the enemy will also know from which side they are firing at him. In patch 1.47, the range of fragments during the explosion of the chamber was increased by almost 2 times, which slightly increased the armor effect of the projectile, increasing the area of ​​destruction.

Advantages

• Good armor penetration and ballistics
• The presence of a chamber with explosive

Flaws

• Moderate armor action

Spr Gr. 34

German 75-mm high-explosive fragmentation projectile model 1934 - 7.5 cm. Sprenggranate 34. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge. Cartridges with a propellant charge differed in length and diameter depending on the design of the breech of the gun. The 5.74 kg projectile is painted dark olive except for the copper guide ring. The chamber occupies almost the entire volume of the projectile and has an exit hole in the front of the projectile. The walls of the projectile at its base are thicker than in the front. One of the modifications of the Kl.A.Z 23 instantaneous or delayed fuse with a deceleration of 0.15 seconds is installed in the head of the projectile. The projectile is stuffed with 0.68 kg of ammotol 40/60 (or TNT) and a red phosphorus smoke bomb.

The sleeve with a length of 495 mm contained 0.78 kg of smokeless powder, a dibasic mixture of nitrocellulose and nitroguanidine, as the main propellant charge. The propelling charge is placed in a bag of rayon. In the center of the bag was a long cylindrical tube of compressed diethylene glycol dinitrate, reaching to the base of the projectile. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St.

There was a training version of the Sprgr. 34 Ub.

Verdict
The only use of a high-explosive fragmentation projectile is firing at unarmored vehicles or at the crew in an open wheelhouse. Despite 700 g of explosive, the explosion radius barely exceeds half a meter, and not so numerous fragments cannot penetrate even thin armor.

Advantages:

• Good at destroying unprotected crew
• High chance to start a fire

Flaws:

• Disgusting armor penetration
• Small explosion radius
• Short range

Gr. 38 Hl/B

German 75 mm HEAT tracer M1938, modification B - 7.5 cm. Granate Hohlladung 38/B. A common German cumulative projectile, produced in various modifications for 75 mm guns. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge. Cartridges with a propellant charge differed in length and diameter depending on the design of the breech of the gun.

The sleeve with a length of 495 mm contained 0.43 kg of smokeless powder, a dibasic mixture of nitrocellulose and nitroguanidine, as the main propellant charge. The propelling charge is placed in a bag of rayon. In the center of the bag was a long cylindrical tube of compressed diethylene glycol dinitrate, reaching to the base of the projectile. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St.

The 4.57 kg projectile is painted dark olive except for the copper guide ring. The chamber occupies almost the entire volume of the projectile. The walls of the projectile at its base are thicker than in the front. One of the modifications of the Kl.A.Z 38 instantaneous fuse is installed in the head of the projectile. The projectile head itself is made of brittle cast iron and is screwed into the steel body of the projectile. The projectile is stuffed with 0.5 kg of Phlegmatized RDX packaged around a central aluminum tube. The top of the explosive charge has a cup-shaped notch, and most of the projectile head is hollow. A perforated aluminum disk was installed at the boundary between the charge and the cavity in the head of the projectile. When a projectile collided with an obstacle, the fuse was triggered, it initiated the explosive charge detonator at the rear of the projectile. During the detonation of the explosive, a compacted gas-dynamic jet was created, which entered the armor through the head of the projectile that collapsed from the impact. The huge pressure of the gas jet greatly exceeds the yield strength of the armor metal, which is why the armor behaves like a liquid and the jet pierces it without any problems. The main striking elements are a hot gas jet and red-hot fragments ("drops") of armor.

Verdict
Like all early HEAT rounds, Gr. Hl. 38/B has a low initial flight speed and therefore poor ballistics. Instantaneous fuse Kl.A.Z 38 gives premature operation when struck by protective screens, trees or fences. The cumulative jet is inferior in terms of armor penetration to an armor-piercing projectile, but has a huge chance of causing a fire or detonation of the module. The presence of a large amount of explosive allows the projectile to be used not only as a cumulative, but also as a high-explosive, albeit with less effect. In polygon conditions, the projectile pierced a 75-mm armor plate at an angle of 30 ° from the normal. The armor penetration of the projectile in the game is slightly lower compared to the German tests - this is essential for hitting heavily armored tanks (such as the KV, T-44 or the T-34-85 turret). The armor effect of a HEAT shell is actually higher than in the game, but it strongly depends on the thickness of the armor that has been pierced. The penetrating power of the cumulative jet drops significantly when flying in the air and drops catastrophically when a projectile is detonated on the screen - up to 5 ~ 10 mm in the main armor behind the screen.

Advantages:

• High chance to cause a fire or explosion of the module
• Ability to use as a high-explosive projectile

Flaws:

• Bad ballistics
• Reduced armor penetration
• Detonation against any obstacle
• Extremely weak armor effect
• Cannot penetrate armor behind the screen

Pzgr. 40

German 75-mm armor-piercing tracer projectile with a ballistic tip, model 1940 - 7.5 cm. Panzergranate 40. A common German armor-piercing sub-caliber projectile. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge.

The sleeve with a length of 495 mm contained 2.18 kg of smokeless powder, a dibasic mixture of nitrocellulose and nitroguanidine, as the main propellant charge. The propelling charge is made in the form of pressed cylindrical tubes 370 mm and 420 mm long, placed in a rayon bag. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St. and a subversive charge weighing 0.315 kg, initiating the detonation of the main propellant charge.

Externally, the projectile looks like a PzGr. 39, but inside it consists of a steel body (serving as a pallet), in the central part of which there is a solid core of tungsten carbide, covered with a ballistic cap. At the bottom of the projectile is a tracer. The projectile received rotation due to the friction of the guide ring on the rifled barrel of the gun. When fired, a tracer ignited, allowing you to track the flight of the projectile. The pallet carried out the centering of the projectile when fired from a cannon and stored kinetic energy for flight. And in combination with a ballistic cap, it provided a high projectile flight speed over a long distance. Upon impact, the steel body of the projectile deformed, releasing a small-caliber hard, pointed tungsten core, which, separated from the pallet, easily pierced the armor.

Verdict
The projectile is not filled with explosives, but due to the high muzzle velocity and small caliber armor-piercing core has excellent ballistics and armor penetration. Ideal for shooting fast moving targets at long range. Weak armor effect may require several hits to destroy the enemy. Like most sub-caliber shells, it has a high cost per unit. Was reduced in patch 1.49 starting speed(L/48) from 990 m/s to 930 m/s and (L/43) from 930 m/s to 919 m/s.

Advantages:

• High armor penetration
• Excellent ballistics and flight speed
• Suitable for hitting heavily armored targets

Flaws:

• Weak armor action
• High price

Pzgr. 40W

German 75-mm armor-piercing tracer with a ballistic tip, model 1940, modification W - 7.5 cm. Panzergranate 40W. A relatively rare German armor-piercing projectile, produced in a limited batch as a cheap replacement for the expensive and scarce PzGr 40 sub-caliber projectile. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge.

The sleeve with a length of 495 mm contained 2.18 kg of smokeless powder, a dibasic mixture of nitrocellulose and nitroguanidine, as the main propellant charge. The propelling charge is made in the form of pressed cylindrical tubes 370 mm and 420 mm long, placed in a rayon bag. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St. and a demolition charge that initiates the detonation of the main propellant charge.

The projectile weighing 4.1 kg consists of a solid steel flat-headed body covered with a ballistic cap. A tracer was screwed into the base of the projectile. The projectile itself was made from blanks for the PzGr. 40 without tungsten core.

Verdict
At its core, it is a solid projectile with a ballistic cap. There is no explosive in it, just as there is no high armor penetration of the Pzgr 40 sub-caliber projectile. Due to the high muzzle velocity, it has good ballistics. It was in service with KwK 40 before patch 1.40.13.0 and is not currently used in the game.

Advantages:

• Good ballistics
• Increased chance to start a fire

Flaws:

• Very weak armor action
• Low armor penetration

K. Gr. rot Pz.

German 75 mm armor-piercing tracer chamber round with armor-piercing and ballistic tip. Sometimes referred to as Pz. Gr. 38 rot or 7.5 Gr. Patr. 38 kwk. When the KwK 40 gun had just left the conveyors, there were not enough new Pzgr. 39. Therefore, at first, a large number of K.Gr. rot Pz. for short-barreled gun 7.5 cm KwK 38 L/24. Namely, a cartridge case with a propellant charge was replaced with a cartridge case for KwK 40. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge.

A 495 mm long cartridge case contained, as the main propellant charge, presumably 2.15 kg of smokeless powder - a dibasic mixture of nitrocellulose and diethylene glycol dinitrate. The propelling charge is made in the form of pressed cylindrical tubes 370 mm and 420 mm long, placed in a rayon bag. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St. and a subversive charge weighing 0.315 kg, initiating the detonation of the main propellant charge.

The projectile consists of a steel body, in the head part of which there is a soft armor-piercing tip covered with a ballistic cap. The armor-piercing tip is attached to the head of the projectile by soldering with fusible solder. In the lower part of the projectile there was a chamber with 0.08 kg of explosive (pressed TNT) and a Bdz detonator combined with a tracer. The projectile received rotation due to the friction of the copper guide ring on the rifled barrel of the gun. When fired, a tracer ignited, allowing you to track the flight of the projectile. The ballistic cap provided a high speed of the projectile over a long distance. The soft armor-piercing tip took on the kinetic energy of the collision of the projectile with the armor, thereby protecting it from destruction and breaking the integrity of the armor, making it easier for the main projectile to work. At high angles of attack, the armor-piercing tip ensured the normalization of the projectile. The sharp-headed steel projectile, crushing the soft armor-piercing tip, crashed into the weakened armor and pierced it, forming a cloud of armor fragments. Cocked on impact, the gas-dynamically retarded bottom detonator detonated the explosive charge when the projectile had already pierced the armor and flew some distance away from it.

Verdict
The shell served as a temporary replacement for the Pzgr. 39.

Advantages:

• More explosives compared to Pzgr 39

Flaws:

• Higher chance of ricochet and projectile destruction than Pzgr 39
• Less armor penetration compared to Pzgr 39

Gr. 38 Hl

German 75 mm HEAT tracer M1938 - 7.5 cm. Granate Hohlladung 38. A common German cumulative projectile, produced in various modifications for 75 mm guns. The projectile was used to a limited extent for firing from this gun. Mostly at the first stages, until mass production of more advanced modifications for this weapon was launched. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge. Cartridges with a propellant charge differed in length and diameter depending on the design of the breech of the gun.

The 4.4 kg projectile is painted dark olive except for the copper guide ring. The chamber occupies almost the entire volume of the projectile. The walls of the projectile at its base are thicker than in the front. One of the modifications of the Kl.A.Z 38 instantaneous fuse is installed in the head of the projectile. The projectile head itself is made of brittle cast iron and is screwed into the steel body of the projectile. The projectile is stuffed with 0.54 kg of a phlegmatized mixture of RDX and TNT, packaged around a central aluminum tube reaching the fuse. The upper part of the explosive charge has a goblet-shaped notch, and the part of the projectile head is hollow. When a projectile collided with an obstacle, the fuse was triggered, it initiated the explosive charge detonator at the rear of the projectile. When the explosive was detonated, a gas-dynamic jet was created, which entered the armor through the head of the projectile that collapsed from the impact. The huge pressure of the gas jet greatly exceeds the yield strength of the armor metal, which is why the armor behaves like a liquid and the jet pierces it without any problems. The main striking elements are a hot gas jet and fragments (“drops”) of armor.

Verdict
The game is missing.

Gr. 38 Hl/C

German 75 mm HEAT tracer M1938, modification C - 7.5 cm. Granate Hohlladung 38/C. A common German cumulative projectile, produced in various modifications for 75 mm guns. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge. Cartridges with a propellant charge differed in length and diameter depending on the design of the breech of the gun.

A sleeve 495 mm long contained 0.5 kg of smokeless powder, a dibasic mixture of Nitrocellulose and Nitroguanidine, as the main propellant charge. The propelling charge is placed in a bag of rayon. In the center of the bag was a long cylindrical tube of compressed diethylene glycol dinitrate, reaching to the base of the projectile.

The walls of the projectile at its base are thicker than in the front. One of the modifications of the Kl.A.Z 38 instantaneous fuse is installed in the head of the projectile. The projectile head itself is made of brittle cast iron and is screwed into the steel body of the projectile. The projectile is stuffed with 0.5 kg of Hexogen-TNT alloy packaged around a central solid aluminum tube. The top of the explosive charge has a cup-shaped notch, and most of the projectile head is hollow. A perforated aluminum disk and a cardboard guide nozzle were installed at the boundary between the charge and the cavity in the head of the projectile. During the detonation of the explosive, a compacted gas-dynamic jet was created, which entered the armor through the head of the projectile that collapsed from the impact.

The main striking elements are a hot gas jet and red-hot fragments ("drops") of armor.

Verdict

Flaws:

• The KwK 40 is not in service

Nb Gr. 40

German 75 mm smoke round 7.5cm Nebel-granate. In its structure, it almost does not differ from the high-explosive fragmentation projectile Sprgr. 34, except for the filler and additional recess in the base. In the wall of the projectile there was a clogged hole for filling the projectile with a smoke-forming mixture. It was a unitary projectile consisting of a shot and a cartridge case with a propellant charge. Cartridges with a propellant charge differed in length and diameter depending on the design of the breech of the gun. The 6.2 kg projectile is painted dark olive except for the copper guide ring. The chamber occupies almost the entire volume of the projectile and has an exit hole in the front of the projectile. The walls of the projectile at its base are thicker than in the front. One of the modifications of the Kl.A.Z 23 Nb instantaneous or delayed fuse is installed in the head of the projectile. The projectile is stuffed with 0.068 kg of picric acid in a cardboard tube running along the center of the chamber from the top of the projectile to its base. The rest of the space is filled with a smoke-forming mixture.

A sleeve 495 mm long contained 0.8 kg of smokeless powder, a dibasic mixture of nitrocellulose and nitroguanidine, as the main propellant charge. The propelling charge is placed in a bag of rayon. In the center of the bag was a long cylindrical tube of compressed diethylene glycol dinitrate, reaching to the base of the projectile. At the base of the sleeve there was an electric ignition mechanism C / 22 or C / 22 St.

Use in combat

This is the most massive tank gun of the Wehrmacht, which fought until the very end of the war and many years later. It has seen almost every possible enemy it has. In the game, tanks with this gun (including the PaK 40) usually face opponents with a combat rating between 2.0 and 6.0. In this range there is a huge number of armored vehicles of various classes and designs. There is no reasonable way to describe the tactics of combat on each machine against all enemies, so the section will be limited to only general guidelines. And for a detailed guide, refer to the corresponding section of the article about the technique using this tool.

Choice of ammunition

There are 4 types of ammunition available for the gun: armor-piercing chamber, high-explosive fragmentation, fragmentation-cumulative and sub-caliber. You definitely should not take a full ammunition load, since if an ammunition rack is hit, it can most likely be detonated (up to 95%). Since it is impossible to remove an already loaded shell from the gun, you should not take all 4 types of shells - you will quickly use up ammunition by firing "inappropriate" shells. It is recommended to take only 2 types of shells - Pzgr. 39 and Pzgr. 40. The first is filled with explosives and is able to deal with lightly armored vehicles, and the second has a huge armor penetration and will allow you to deal with heavily armored vehicles. High-explosive fragmentation projectile Sprgr. 34 is practically useless, since it cannot penetrate the armored shields of light vehicles that pose a danger to you. A machine gun will better cope with this task, or if you don’t have one, then the usual armor-piercing-chamber projectile Pzgr. 39. High-explosive fragmentation impact of the Gr. HL 38/B is slightly weaker than Sprgr. 34, so it works even worse against light vehicles. The cumulative jet, although it has a high chance of setting fire to / blowing up a gas tank / ammo rack, is still inferior to the same effect from the explosion of the Pzgr chamber. 39, and insufficient armor penetration and armor effect do not make the projectile so effective.

Combat tactics

Equipment with this gun has weak armor, and the gun itself has good ballistics at a distance of 1000-1500 meters. Projectiles don't have a lot of armor penetration, so don't expect to take out a target with one shot and be prepared to land another one or retreat to cover.

If you knocked out the barrel, use the mount to fight the enemy.

• Your main friend is distance. At a distance it's easier for you to hit most enemies than them you.
• The gun elevation angles on tanks allow you to shoot behind hills.
• Take cover behind a hill and use your binoculars to safely reconnoiter surrounding area and "jump out" of the ambush, finding the enemy.
• Staying in cover behind the hill, use the binoculars for aiming and "mounted" shooting.
• The most vulnerable enemy module is the ammo rack, try to hit it.
• Shooting at the side of the enemy's turret will allow you to hit several key modules at once - the crew, ammunition rack, breech and turret drive system.
• For shooting at fast moving targets, it is best to use sub-caliber shells Pzgr 40 with high speed, but also armor-piercing chamber Pzgr 39.
• The engine of most enemies can be destroyed with a single Pzgr 39 hit.
• If you have a heavily armored tank in front of you, whose armor you cannot penetrate, then try to destroy its barrel - this will give you time to change position or allow you to hit it in a weak spot. To destroy the enemy's barrel, three Pzgr 39 shells are fired.
• When fighting against high-level vehicles, try to flank them, as such vehicles can destroy you from a long distance.
• Your rate of fire is faster than most enemies, but your projectiles are weaker.
• Win.
• The Pzgr 39 can be used against most targets, and the Pzgr 40 against the most heavily armored.
• Work in a team.

Low level light armored vehicles This includes small-caliber tanks and light anti-aircraft guns. They pose a danger only to close range (<500 метров). В то же время, вы можете поразить их с любой дистанции. Стоит опасаться фланговых атак такой техники.

Light armored vehicles of medium and high level This includes light tanks and self-propelled guns, as well as large-caliber anti-aircraft guns. Of particular danger are high-speed anti-aircraft guns that can penetrate your armor at a distance of up to 1000 m. Try to determine their location by sound and tracers and catch them by surprise or cover them with artillery support.

medium tanks This includes medium tanks of initial and medium levels with a comparable gun. You are dangerous to each other, but you have a higher rate of fire and more accurate guns. Take advantage of this. If your armor allows, then try to "diamond" at a distance or try to go from the flank.

High Tier Medium Tanks This includes medium tanks that can confidently hit you at a distance of 1000 m. They are extremely dangerous and can destroy you with one shot. Try to shorten the distance and enter from the flag. Another tactic might be a well-laid ambush, but don't expose yourself until the enemy is within safe range.

Self-propelled guns This includes Soviet self-propelled guns: both short-barreled (for example, SU-122) and long-barreled (for example, SU-85). They are deadly even at long distances. The angles of inclination and the thickness of the frontal armor will not allow you to easily hit the fighting compartment of the self-propelled gun. Armor-piercing shells will penetrate your armor even at a distance of 1800 m, and high-explosive high-explosive shells can destroy you even if they hit you next to a tank. Deadly in a head-on collision at close range, but vulnerable to outflanking. It is most effective to hit the side, which almost always leads to the destruction of self-propelled guns with one shot.

Medium Heavy Tanks This includes heavy tanks, which you can penetrate without much difficulty with the main projectile (KV-1 and M6A1). These tanks are capable of destroying you from a distance, while their armor will protect you from your projectiles. To defeat heavy tanks, it is better to get close to them at least at an average distance and target weak points in the armor. To defeat enemies at long distances, it would be better to use a sub-caliber projectile. Like any other tanks, they are vulnerable to flank attacks. Your advantage is maneuverability and sometimes rate of fire.

High Tier Heavy Tanks This includes heavy tanks with frontal armor above the Pzgr 39 armor penetration limit (IS and Sherman Jumbo). Extremely dangerous. Part of the tanks can be hit in the weak spots of the armor or on the side. The best way to do this is to ambush and flank. You can also try to immobilize a heavy tank and cover it with artillery. You can also try to knock out his barrel, making it an easy target for other members of your team.

Aviation For experienced pilots, you are not a priority target, but a frag is a frag. Hide from aircraft in the woods and between buildings. Don't move in a large group, especially near heavy tanks. In some cases, you can destroy a low-flying enemy aircraft with a projectile, in particular, an aircraft approaching you. Remember that the rate of fire of the gun is enough for you only for one shot.

tank bots It will not be easy for you to destroy the enemy tank bots, since the KwK 40 shells have a weak armor effect, and the bots do not have an ammo rack. Try to hit the tank crew or use artillery against enemies standing still. If your ammo is low, then ignore the bots.

Artillery and other stationary targets Computer artillery is dangerous for you, but you can destroy it with any projectile. Therefore, use binoculars for reconnaissance of the location of the artillery. Large groups of enemies can be covered with artillery strikes.

History of creation
The development of the PaK40 began in 1938 according to the terms of reference issued by two firms, Krupp and Rheinmetall. The pace of creation was initially low, only in 1940 were prototypes of guns presented, of which the Rheinmetall gun was recognized as the best. Compared to the 37-mm anti-tank gun already adopted by the Wehrmacht. PaK40 turned out to be heavy and not so mobile, requiring a specialized artillery tractor for transportation, especially on soils with weak bearing capacity. She did not fit into the concept of "blitzkrieg" and therefore an order for mass production in 1940 was not followed. On the other hand, the battles in France with the Allied S-35, B-1Bis and Matilda tanks, which had anti-projectile armor, demonstrated the need for a gun with the characteristics of PaK40. However, in the subsequent campaigns of the Wehrmacht in Yugoslavia and Crete, the purposes for which the PaK40 might be needed were not found, and the question of organizing its serial production was postponed to the future.

The situation changed after the invasion of Nazi Germany into the territory of the Soviet Union. The Wehrmacht's 37mm guns were more than successful against the lightly armored Soviet BT and T-26 tanks, but were virtually useless against the new T-34s and KVs. The introduction of the 50-mm PaK38 anti-tank gun somewhat improved the Wehrmacht's ability to fight new Soviet tanks, but this gun also had significant drawbacks. The most important of them are:
Only a 50-mm sub-caliber projectile could confidently penetrate the armor of a T-34 or KV, and according to reports from TsNII-48, the armor action of the ceramic-metal core of this projectile was weak (it crumbled into sand and sometimes a regular tanker jacket was enough to protect against this sand) . According to the statistics of defeats of the T-34 tank in late 1941 - early 1942. 50% of the hits of 50-mm shells were dangerous, and the probability of incapacitating the T-34 with one hit of a 50-mm shell was even lower.
Tungsten was used as the material for the ceramic-metal core, and its stocks in the Third Reich were very limited.
Weak action PaK38 on unarmored targets.

However, while there was still hope for a "blitzkrieg", the Wehrmacht leadership was in no hurry to adopt the PaK40. But by the end of the autumn of 1941, it became clear to the German military that the disorganization of the Soviet troops was largely overcome and the number of T-34s on all fronts began to increase steadily. This made them a very dangerous adversary and the existing means to deal with them were officially recognized as insufficient. As a result, the PaK40 was put into service in November 1941, and the first mass-produced guns were delivered to the anti-tank artillery of the Wehrmacht.

In 1942, the gradual re-equipment of all parts of the Wehrmacht anti-tank artillery with PaK40 began, which was finally completed by the beginning of 1943. Reports from the Soviet tank troops in early 1943 emphasize that the main caliber of German anti-tank artillery is 75 mm, and the percentage of defeats with smaller calibers is such that it can be ignored. All hits of the 75 mm caliber in the T-34 were considered dangerous. The PaK40 thus ended the dominance of the T-34 on the battlefield.

The gun in 1942-45 was an effective tool against any Allied medium tank that fought, so its production continued until the very end of World War II. Reliable protection against its fire was realized only in the IS-2 and T-44 tanks (the latter did not take part in hostilities). As for the first, the statistics on irretrievably disabled IS-2s was such that 75 mm caliber accounted for 14% of losses (the rest was 88 mm caliber and cumulative Faustpatrons). During the war, the British did not manage to create a tank with reliable anti-shell armor; in the USA, it was the M26 Pershing, which was resistant to PaK40 fire.

The PaK40 anti-tank gun was supplied to Germany's allies - Hungary, Finland, Romania and Bulgaria. With the transition of the last three in 1944 to the anti-Hitler coalition, PaK40 in the armed forces of these countries were used against the Germans. These guns were in service with their armies after the end of World War II. Captured PaK40s were also actively used in the Red Army.

Tool production

In total, 23,303 PaK40 towed guns were produced in Nazi Germany and about 2,600 more barrels were mounted on various self-propelled gun carriages (for example, Marder II). It was the most massive weapon produced in the Reich. The cost of one gun was 12,000 Reichsmarks.

Also guns were mounted on some different types of chassis:
Sd.Kfz.135 Marder I - in 1942-1943, 184 self-propelled units were manufactured on the basis of the French Lorraine semi-armored tractor.
Sd.Kfz.131 Marder II - in 1942-1943, 531 self-propelled units were manufactured on the basis of the light tank Pz.IIA and Pz.IIF.
Sd.Kfz.139 Marder III - in 1942-1943, on the chassis of the Czech tank 38 (t), 418 installations were manufactured in the "H" variant (engine in the stern) and 381 installations in the "M" variant (engine in the front of the chassis).

Combat use

PaK40 was used in the vast majority of cases as an anti-tank gun, firing at its targets with direct fire. In terms of armor-piercing action, the PaK40 was superior to the similar Soviet 76.2 mm ZiS-3 gun, but this was largely due to the better quality and production technology of German shells compared to Soviet ones. On the other hand, the ZiS-3 was more versatile and had better action against unarmored targets than the PaK40.

Toward the end of the war, the production of anti-tank guns in Nazi Germany was given one of the highest priorities. As a result, the Wehrmacht began to experience a shortage of howitzers. For at least some of their replacement, PaK40 began to be used for firing from closed positions on the model of the ZiS-3 divisional cannon in the Red Army. This decision had another advantage - in the event of a deep breakthrough and the tanks reaching the positions of German artillery, the PaK40 again became an anti-tank gun. However, estimates of the scale of the combat use of PaK40 in this capacity are very controversial.

In 1939, Rheinmetall-Borsig began designing a 75 mm anti-tank gun, called the 75 mm PaK-40. The first 15 guns of the Wehrmacht unit, located on the Eastern Front, received only in February 1942. The main purpose of the gun was to fight tanks and armored vehicles, however, a sufficiently large caliber and the presence of a high-explosive fragmentation projectile in its ammunition load made it possible to use the gun to suppress firing points, destruction various light obstacles and for the destruction of enemy manpower. In total, more than 23,303 PaK-40 guns were manufactured during the war years.

More PaK-40 anti-tank guns were produced than any other Reich guns. The table below shows this.

production of the 75 mm PaK-40 gun:

1942	2114 pieces;
1943	8740 pieces;
1944	11728 pieces;
1945	721 pieces;
Total:	23303 pcs.

In addition to the wheeled carriage of the PaK-40 gun in 1942-1944. installed on several types of chassis:
1. Sd.Kfz.135 "Marder I" on the chassis of the French tank "Laurent". In 1942-1943. 184 self-propelled units were manufactured;
2. Sd.Kfz.131 "Marder II" on the chassis of the T-PA and T-PR tanks. In 1942-1943. 531 self-propelled units were manufactured;
3. Sd.Kfz.139 "Marder III" on the chassis of the tank 38(t). In 1942-1943 418 self-propelled units were manufactured in the "H" variant (engine in the stern) and 381 units in the "M" variant (engine in the front);
4. 39 H(f) on a Hotchkiss chassis. In 1943-1944. 24 self-propelled units were manufactured;
5. On the R.S.M. (f) chassis in 1943-1944. 10 self-propelled units were manufactured;
6. 164 self-propelled guns were made on the chassis of the PzKpfw IV tank;
7. On the chassis of the caterpillar tractor K50;
8. On the chassis of the semi-tracked medium armored personnel carrier SM 251/22;
9. On the chassis of a wheeled (4x2) armored personnel carrier CM 234/4.

The main parts of the PaK-40 gun are: a barrel with a bolt, a cradle with recoil devices, an upper machine, lifting, turning and balancing mechanisms, a lower machine with undercarriages, shield cover and sights. The monobloc barrel is equipped with a highly effective muzzle brake, which absorbs a significant part of the recoil energy. The carriage with sliding beds provides the possibility of firing at elevation angles from -3 ° 30 "to +22 °. The angle of horizontal fire is 58 ° 30". When the gun is rolled by the calculation forces, the trunk part of the gun is installed on the guide wheel. In this case, the gun moves muzzle forward. One person guides the implement using the guide arm.

For transporting the implement using a tractor, it is equipped with pneumatic marchingbrakes, which are controlled from the cab of the tractor. In addition, you can brake using levers located on both sides of the gun carriage. The shield cover is similar in design to the cover of the PaK-38 gun and consists of an upper and lower shield. The upper shield is fixed on the upper machine and consists of two sheets - rear and front. The lower shield is fixed on the lower machine and has a folding part. The shutter of the gun is equipped with semi-automatic, which provides a fairly high rate of fire - 12-14 rounds per minute. The ammunition load of the PaK-40 cannon includes cartridge-loading shots with the following types of projectiles:
- high-explosive fragmentation grenade;
- armor-piercing tracer projectile mod. 39;
- armor-piercing tracer sub-caliber projectile mod. 40;
- cumulative projectile.

For firing at heavily armored targets at short ranges (up to 600 m), cumulative projectiles weighing 4.6 kg were used. At an encounter angle of 60°, these shells pierced 90 mm thick armor, which made it possible to successfully use the PaK-40 cannon to combat a significant part of the armored vehicles of the USSR and its allies.

PaK-40 losses were enormous. Until March 1, 1945, Germany lost 18,096 of these guns. Only in 1944 the losses amounted to:

period - losses:

September 1944	669 pieces;
October 1944	1020 pieces;
November 1944	494 pieces;
December 1944	307 pcs.

The gun was produced until the end of the Second World War. Its carriage was also used to create a modernized 105-mm light field howitzer mod. 18/40 and 75 mm PaK-97/40 anti-tank gun, which was an overlay of the barrel of a 75 mm French gun mod. 1897 on the gun carriage PaK-40.

75 mm anti-tank gun Rak 40

The Pak 38 was still being tested, and the Rheinmetall-Borsig designers in 1938 began designing an even more powerful 75-mm anti-tank gun. At first, they tried to get by with what is called “little blood” - the first samples of the new gun were a proportionally enlarged Pak 38 gun. carriage of a 50-mm gun, and above all - tubular beds, could not withstand the sharply increased loads. It was necessary to completely redesign the gun, but the work was carried out at a slow pace - simply, the Wehrmacht did not feel the need for an anti-tank gun more powerful than the Pak 38.

The impetus to accelerate work on the 75-mm gun was given by the start of the war against the USSR, namely, the collision with the T-34 and KV tanks, which we have repeatedly mentioned. The company was instructed to urgently complete the refinement of the Pak 40. In December 1941, prototypes of the guns were tested, serial production began in January of the following year, and already in February the first 15 Pak 40s entered the troops.

105 mm leFH18 anti-tank gun

The weight of Pak 40 in combat position was 1425 kg. The gun had a monoblock barrel with a highly effective muzzle brake. The barrel length was 3450 mm (46 calibers), and its rifled part was 2461 mm. The horizontal wedge semi-automatic shutter provided a rate of fire of 12-14 rds / min. The maximum firing range was 10,000 m, the direct firing range was 2,000 m. The carriage with sliding beds provided a horizontal aiming angle of 58 °, vertical - from -6 ° to + 22 °. The carriage had sprung wheels with solid rubber tires (there were two types of wheels - with solid discs with lightening holes and spoked). Permissible towing speed - 40 km / h. The gun was equipped with pneumatic marching brakes, which were controlled from the cab of the tractor. It was possible to brake manually - by means of two levers located on both sides of the gun carriage. The calculation of the gun - eight people.

Ammunition Rak 40 consisted of unitary shots with the following types of projectiles:

SprGr - fragmentation projectile weighing 5.74 kg. The initial speed of the projectile - 550 m / s;

PzGr 39 - armor-piercing tracer weighing 6.8 kg. Initial speed - 790 m / s, armor penetration - 132 mm at a distance of 500 m and 116 - at 1000 m;

PzGr 40 is an armor-piercing 4.1 kg sub-caliber projectile with a tungsten core. Initial speed - 990 m / s, armor penetration - 154 mm at a distance of 500 m and 133 mm at 1000 m;

HL.Gr - cumulative projectile weighing 4.6 kg. It was used to destroy armored targets at distances up to 600 m.

The cost of the Pak 40 gun was 12,000 Reichsmarks. Pak 40 was the most successful and most massive anti-tank gun of the Wehrmacht. The scale of its production is evidenced by the figures of the average monthly production, which in 1942 amounted to 176 guns, in 1943 - 728 and in 1944 - 977. The largest monthly production was recorded in October 1944, when 1050 Pak 40 were manufactured. In 1945, due to the destruction of a significant part of the industrial potential of the Third Reich, the rate of production of Pak 40 decreased significantly - from January to April inclusive, 721 such guns were manufactured. The total production of Pak 40 amounted to 23,303 units, of which more than 3,000 were used in self-propelled guns.

In 1942, on the basis of Rak 40, Gebr. Heller, a 75-mm anti-tank gun Pak 42 was developed, which was distinguished by a longer barrel (71 calibers instead of 46). Only 253 of these cannons were made on a field carriage. Subsequently, Pz.IV(A) and Pz.IV(V) tank destroyers were armed with Pak 42 guns without a muzzle brake.

In 1944, an attempt was made to create a lightweight version of the 75 mm anti-tank gun. The new gun, which received the designation Cancer 50, had a barrel shortened to 30 calibers, superimposed on the carriage of a 50-mm Cannon Cannon 38. At the same time, it was not possible to manage with a minimum of alterations - the aluminum frames of the original sample had to be replaced with steel ones. As a result, the weight of the gun decreased, but not to the extent that was expected (up to 1100 kg), but the armor penetration significantly decreased and amounted to 75 mm for the PzGr 39 projectile at a distance of 500 m. The gun ammunition included the same types of shells as for Pak 40, but the size of the cartridge case and powder charge were reduced. The production of Pak 50 lasted from May to August 1944, and the production volume was relatively small - 358 units.

"Pak-35/36" is the result of a modification of the "Pak-29" gun, produced in 1935-1936. The new gun had a light two-wheeled carriage with sliding beds, a sprung wheel travel, metal wheels with rubber tires, a horizontal wedge horizontal shutter with an automatic closing mechanism. The recoil brake is hydraulic, the knurler is spring. The carriage is equipped with wheels with rubber tires. Based on the Pak-35/36, the KwK-36 L/45 tank variant was produced, which was used to arm the early models of the PzKpfw-III tank. "Pak-35/36" was installed on a large number of different (including trophy) chassis. The gun ammunition consisted of caliber armor-piercing, sub-caliber armor-piercing, cumulative and fragmentation shells.

Many countries purchased from Germany either the guns themselves or a license for their production, in particular, Turkey, Holland, Japan, Spain, Italy. A total of 16.5 thousand guns were fired. TTX guns: caliber - 37 mm; length - 3.4 m; width - 1.6 m; height - 1.2 m; clearance - 270 mm; barrel length - 1.6 m; weight - 440 kg; calculation - 5 people; rate of fire - 15 rounds per minute; armor penetration - 25 mm at a distance of 500 m at a meeting angle of 60 °; transportation speed on the highway - up to 50 km / h; the height of the line of fire - 620 mm.

The 42-mm gun of the 1941 model of the Rheinmetall company with a conical bore was put into service in 1941. The gun was used by the airborne troops. The initial diameter of the barrel is 40.3 mm, the final one is 29 mm. The gun was mounted on a gun carriage from the Pak-35/36 gun. The shield cover consisted of two 10-mm armor plates. A total of 313 guns were made. TTX guns: caliber - 40.3 mm; length - 3.6 m; width - 1.6 m; height - 1.2 m; barrel length - 2.2 m; weight - 642 kg; ammunition - 42 × 406R weighing 336 g; effective firing range - 1000 m, road transport speed - 50 km / h. The initial speed of the armor-piercing projectile was 1265 m/s. At a distance of 500 m, it pierced 72 mm armor at an angle of 30 °, and along the normal - 87 mm armor.

The gun was manufactured by Rheinmetall and put into service in 1940. The gun had upper and lower armored shields. The top shield is double of two steel sheets 4 mm thick each. When moving the "Pak-38" manually, a light front end with one guide wheel was connected to the gun. The gun was supplied with unitary shots: armor-piercing shells, sub-caliber and fragmentation. A total of 9.5 thousand guns were manufactured. TTX guns: caliber - 50 mm; length - 4.7 m; width - 1.8 m; height - 1.1 m; barrel length - 3 m; weight - 930 kg; clearance - 320 mm; calculation - 5 people; rate of fire - 14 rounds per minute; initial speed - 550 - 1130 m / s, depending on the type of projectile; maximum firing range - 9.4 km; projectile weight - 2 kg; armor penetration - 95 mm at a distance of 500 m at a meeting angle of 60 °; transportation speed - up to 35 km / h.

The gun was an overlay of the swinging part of the 75-mm Schneider cannon of the 1897 model on the carriage of the German Pak-38 anti-tank gun. The prerequisite for this was the capture of captured 75-mm divisional guns mod. 1897 in Poland and France. In addition to the main variant, 160 7.5-cm Pak-97/40 guns were fired, representing the imposition of the barrel of a French gun on the carriage of the Pak-40 anti-tank gun. The gun had sliding beds, sprung wheels, metal wheels with rubber tires. The barrel was equipped with a muzzle brake. The guns were provided with cumulative shells that pierced 90 mm armor at a distance of 1000 m at an angle of 90°. The gun was used in Romania and Finland. A total of 3.7 thousand guns were fired. TTX guns: caliber - 75 mm; length - 4.6 m; width - 1.8 m; height - 1 m; barrel length - 2.7 m; weight in the stowed position - 1.2 tons, in combat - 1.1 tons; rate of fire - 14 rounds per minute; calculation - 6 people; the speed of transportation on the highway is 35 km / h.

The development of the PaK-40 began in 1938 by Rheinmetall, however, the weapon was adopted only in November 1941, which put an end to the dominance of the T-34 on the battlefield. The gun was supplied to Germany's allies: Hungary, Finland, Romania and Bulgaria. About 2 thousand guns were installed on various types of self-propelled chassis under the designation Marder (I-III). A total of 23.3 thousand guns were manufactured. TTX guns: caliber - 75 mm; length - 5.7; width - 2 m; height - 1.25 m; clearance - 320 mm; weight - 1500 kg; barrel length - 3.4 m; armor penetration of a projectile weighing 6.8 kg with an initial speed of 790 m / s - 85 mm at a distance of 1000 m; rate of fire - 15 rounds per minute; calculation - 8 people; the speed of transportation on the highway is 40 km/h.

"Pak-36 (r)" was a deep modernization of the Soviet 76-mm divisional gun model 1936 (F-22). The gun had sliding beds, sprung wheels, metal wheels with rubber tires. The Pak-36 (r) limber was not completed and moved exclusively on mechanical traction. Most of the guns were adapted for installation on Marder-II / III anti-tank self-propelled guns. For these guns, 2.9 million high-explosive fragmentation shells and 1.3 million armor-piercing shells were produced. As a result of the modernization of the gun, the armor penetration of a caliber projectile at a distance of 900 m at a meeting angle of 90 ° reached 108 mm, and a sub-caliber projectile - 130 mm. In total, about 1,300 units were rebuilt. TTX guns: caliber - 76.2 mm; barrel length - 3.8 m; weight - 1.7 tons; rate of fire - 12 rounds per minute; fire line height - 1 m; transportation speed on the highway - up to 30 km / h.

A gun with a conical bore (from 75 to 55 mm) was produced in 1941-1943. A feature of the design of the gun was the absence of the upper and lower machines of the usual design. The lower machine gun was a shield, consisting of two parallel armor plates, reinforced to increase rigidity by intermediate bulkheads. A cradle with a ball segment, a course with a suspension mechanism and guidance mechanisms were attached to the shield. The system was transported by mechanical traction. The stroke is equipped with a pneumatic brake controlled by the tractor driver. The wheels are metal with solid rubber tyres. A total of 150 guns were made. TTX guns: caliber - 75 mm; length - 4.3 m; width - 1.9 m; height - 1.8 m; weight in the stowed position - 1.8 tons, in combat - 1.3 tons; clearance - 320 mm; ammunition - 75 × 543R; fire line height - 0.9 m; effective firing range - 2 km; rate of fire - 14 rounds per minute; armor penetration of a projectile weighing 2.6 kg with an initial speed of 1125 m / s - 143 mm at a distance of 1000 m; calculation - 5 people.

The 8H.63 gun was created by Rheinmetall and was produced from December 1944. It was a smooth-bore anti-tank gun with a double chamber. The cannon fired feathered projectiles. A total of 260 guns were fired. TTX guns: caliber - 81.4 mm; gun length - 5.2 m; width - 1.7 m; height - 1.9 m; barrel length - 3 m; weight - 640 kg; calculation of 6 people; rate of fire - 8 rounds per minute; ammunition weight - 7 kg; projectile weight - 3.7 kg; explosive mass - 2.7 kg; initial speed - 520 m / s; rate of fire - 8 rounds per minute; barrel recoil length - 670 mm; effective firing range - 1.5 km; calculation - 6 people.

The 88-mm Pak-43 anti-tank gun was developed on the basis of the Flak-41 anti-aircraft gun and was put into service in 1943. The Pak-43 gun was placed on a four-axle carriage, which made it possible to fire at armored vehicles in all directions. The carriage carriage had independent suspension for each wheel. When transferred from a marching to a combat gun, it was lowered onto four supports, which gave it stability during firing in any direction and at all elevation angles.

In order to simplify the design and reduce the dimensions of the Pak-43, the gun barrel was mounted on a single-axle carriage, similar in type to the Pak-40 gun. This variant was designated "Pak-43/41". Based on the Pak-43, the KwK-43 tank gun and the StuK-43 gun for self-propelled guns were developed. These guns were armed with a heavy tank PzKpfw VI Ausf B "Tiger II" ("Royal Tiger"), tank destroyers "Ferdinand" and "Jagdpanther", self-propelled guns "Nashorn" ("Hornisse"). The gun was equipped with ammunition with armor-piercing (projectile weight - 10 kg, muzzle velocity - 810-1000 m / s, armor penetration - 100 mm at a distance of 1000 m at a meeting angle of 90 °), sub-caliber (weight - 7.5 kg, muzzle velocity - 930 -1130 m / s, armor penetration - 140 mm at a distance of 1000 m at a meeting angle of 90 °), cumulative (7.6 kg, initial speed - 600 m / s, armor penetration - 90 mm at a distance of 1000 m at a meeting angle of 90 °) and high-explosive (weight - 7.6 kg, initial speed - 600 m / s) shells. In total, 3.5 thousand guns were made. TTX guns: caliber - 88 mm; rate of fire - 6-10 rounds per minute; barrel length - 6.2 m; weight in the stowed position - 4.9 tons, in combat - 4.4 tons, firing range - 8.1 km.

The 128 mm gun was put into service in 1944 and was manufactured by Krupp. Depending on the purpose and design changes, the gun was known as: "K-44", "Pak-44", "Kanone-81", "Pak-80" and "Pjk-80". The gun was mounted on a special carriage of circular rotation, which provided an angle of maximum elevation of 45 °. The gun had a shield cover. The cannon was armed with self-propelled guns Jagdtiger (Sd.Kfz 186). A total of 51 guns were fired. TTX guns: caliber - 128 mm; weight - 10.1 tons; barrel length - 7 m; projectile weight - 28 kg; initial speed - 935 m / s; maximum firing range - 24 km; rate of fire - 4-5 rounds per minute; clearance - 320 mm, armor penetration - 200 mm at a distance of 1000 m and 148 mm at a distance of 2000 m; calculation - 9 people.
