203 mm howitzer of the sample of 1931, known under the factory designation B-4-4It became one of the most powerful artillery pieces of the Red Army during the Great Patriotic War. Developed on the basis of captured guns First World WarThis howitzer combined unique for its time range (up to 18 km) with the destructive power of a projectile weighing almost 100 kg. Its creation was a response to the need for heavy artillery, capable of penetrating the long-term defensive structures of the enemy.
Although B-4 was in the category of artilleryIt was often involved in strategic tasks, from the destruction of fortified points to counter-battery warfare. The gun was actively used from the 1930s until the end of World War II, and individual copies remained in service with some countries until the 1970s. Today, the B-4 is not only a museum exhibit, but also an object of close attention of military equipment collectors, historians and modelers.
History of creation and modification of howitzer B-4
Work on the Soviet 203-mm howitzer began in the late 1920s on the basis of captured guns German firm Kruppcaptured during the First World War. The chief designer of the project became B.I. ShavyrinUnder the leadership of which was created a tool that surpasses foreign analogues in a number of parameters. The first prototypes were received for testing in 1930, and mass production was launched in 1931. Perm plant No. 172 (now the Motovilikhin factory).
Over the years of release, the B-4 howitzer has undergone several modifications:
- ๐น B-4 (1931) - Basic version with muzzle brake and separate sleeves.
- ๐น B-4M (1936) - Modernized model with reinforced carriage and improved ballistics.
- ๐น B-4-20 (1941) - an option with an increased range of fire (up to 20 km) due to new powder charges.
Production of the B-4 was suspended in 1941 due to the evacuation of factories, but resumed in 1942. Ural Plant of Transport Machinery Engineering. In total, during the war, about 900 units were produced, which made it one of the most massive heavy howitzers of the USSR.
Technical specifications and device
Howitzer B-4 belonged to the class field-artillery and had the following key parameters:
| Parameter | Meaning |
|---|---|
| caliber | 203 mm |
| The length of the barrel | 50 calibers (10.15 m) |
| Mass in combat position | 17.7 t |
| Maximum range of fire | 18,000 m (B-4) / 20,000 m (B-4-20) |
| Rate of fire | 1 shot at 2-3 minutes |
Structurally, the B-4 consisted of the following main nodes:
- ๐ง Gun - monoblock, with muzzle brake to reduce rollback.
- ๐ง Lafette
- ๐ง Shutter. - piston, with semi-automatics (opened automatically after the shot).
- ๐ง Targeting devices - Hertz panorama and mechanical quadrant.
The B-4 feature was split-case loaderwhere the projectile and charge were placed in a brass sleeve. This simplified recharging, but required high calculus qualification. For transportation, the gun was disassembled into two parts: a barrel and a carriage, which were transported on special roller-box or squatters of the "Voroshilovets".
When shooting at maximum range, the calculation of the B-4 used variable-charge (up to 15 kg of gunpowder), which required special care when loading due to the risk of sleeve burnout.
Combat use and tactics of use
B-4 howitzers were actively used in all major operations of the Great Patriotic War, starting with the war. defense of Leningrad and ending storm-storm. Their main objectives are:
- ๐ฅ Destruction of long-term defensive structures (DOTs, DZOTs).
- ๐ฅ Counter-battery fighting is the suppression of enemy artillery positions.
- ๐ฅ The shelling of clusters of equipment and manpower at a long range.
- ๐ฅ Participation in artillery preparation before the offensive (for example, in Operation Bagration).
The tactics of using the B-4 had its nuances. Due to their heavy weight and low mobility, guns were usually placed in pre-arranged firing positions, masking them from aerial reconnaissance. Calculation from 10โ12 people He could fire until there was a threat of a counterattack. In such cases, the howitzer was evacuated with the help of tractors or even T-34 tanksTo which special towing devices were attached.
โ ๏ธ Attention: When firing on full charges, the recoil of the barrel of the B-4 reached 1.2โ1.5 mThis required a reliable fixation of the carriage in the ground. Failure to comply with this rule could lead to the rollover of the gun or damage to the stanzas.
Interesting fact: in The Battle of Stalingrad B-4 howitzers were used to shell German positions on the other side of the Volga River. Their shells penetrated the walls of houses and bunkers, which greatly complicated the defense of the 6th German Army.
Comparison with foreign analogues
In its characteristics, the B-4 was not inferior, and in some respects surpassed heavy howitzers of other countries. For clarity, we will give a comparative table:
| Model | Country. | caliber | Range, m. | Mass of projectile, kg |
|---|---|---|---|---|
| B-4-4 | USSR | 203 mm |
18 000โ20 000 |
97โ100 |
| sFH 18 | Germany | 150 mm |
13 325 |
43,5 |
| BL 8-inch Howitzer | UK | 203 mm |
16 970 |
90,7 |
| M115 | USA | 203 mm |
16 916 |
90,7 |
As you can see from the table, the Soviet howitzer won against the German sFH 18 the range and power of the projectile, and the American M115 The maximum distance of shooting. ~British BL 8-inch It was very similar in performance, but was inferior in mobility due to the lack of muzzle brake.
Benefits of B-4:
- โ
High penetration (concrete shell punched to the point of collapse)
1.5 m of reinforced concrete). - โ The ability to fire from closed positions due to the long range.
- โ Relative simplicity of design, facilitating repair in the field.
Among the shortcomings stood out low-rate (due to manual loading) and transportation (A powerful tractor or disassembly into parts was required).

Where can I see the B-4 in action?
Every year, at the training ground in Alabino (Moscow region) there are demonstrations of historical equipment, where they sometimes demonstrate firing from restored B-4 howitzers. However, due to the rarity of ammunition, such events are held no more than 1-2 times a decade.
For collectors and restorers, the B-4 is of particular value. At auctions of military equipment, individual gun components (for example, a shutter or sighting devices) can cost up to 50 thousand rubles - 100 thousand rublesAnd the full line is over. 5 million rubles.
Modeling and replicas: how to build B-4 with your own hands
The B-4 howitzer is popular among modelers due to its recognizable shape and historical significance. There are several ways to create a smaller copy:
- Ready kits companies Zvezda (Russia) and ICM Ukraine to produce plastic models of B-4 on a scale
1:35and1:72. - 3D printing - digital models for printing on a 3D printer are available on the Internet (for example, on the Internet) Thingiverse or Cults3D).
- Homemade lines - enthusiasts make copies of wood, metal or foam with subsequent painting.
To build an accurate model will require:
โ๏ธ What you need to build a model B-4
Particular attention in modeling is paid to:
- ๐จ Muzzle brake - should have characteristic slits.
- ๐จ Lafette - Stans are often depicted with bent elements that simulate combat damage.
- ๐จ Targeting devices It is better to highlight them with silver paint.

Interesting facts and myths about howitzer B-4
With howitzer B-4 associated with many legends and little-known facts:
- ๐ฃ "Earthquake shell" - the so-called high-explosive projectile B-4 because of its ability to cause seismic fluctuations when hit. V Kursk These shells were used to destroy German tank ambushes.
- ๐ Railway version In 1943, an experimental version of the B-4 was created on a railway platform.TM-1-203), but he didn't go into the series.
- ๐ฏ Record shot In 1944, a B-4 crew under the command of Senior Lieutenant Ivanov struck the German headquarters at a distance.
20 300 mThis is an absolute record for this weapon.
There is a myth that the B-4 could have shot. nuclear-armed. In fact, although in the post-war years experiments were conducted with artillery nuclear munitions (for example, for the purpose of the nuclear weapons). 280mm Br-5 mortars), for the B-4, such projectiles were never developed due to insufficient power.
Another misconception is that the B-4 howitzer was self-propelled. In fact, self-propelled variants on its basis were not created, although in the 1940s a project was considered to install the barrel of the B-4 on the chassis of the tank. IS-2 German analogue Hummel).
The B-4 howitzer remains the only Soviet 203 mm gun that was actively used in all major operations of the Great Patriotic War and has survived in significant numbers to this day.
