Multiple launch rocket system BM-13 "Katyusha" - one of the most famous Soviet weapons of the Second World War - was developed by a team of engineers led by Andrey Kostikov and Georgy Langemak. The first prototypes appeared back in 1938–1939, but mass production was launched only in 1941, when the USSR urgently needed mobile and powerful weapons to counter the Wehrmacht. The Katyusha design was based on a modified truck chassis ZiS-6, and rockets M-13 were developed in parallel at NII-3 under the leadership Ivana Gvai.
Despite myths about its “handicraft” origins, the system was the result of many years of research in the field of rocket artillery, which began back in the 1920s. Played a key role Jet Research Institute (RNII), where not only Kostikov and Langemak worked, but also such specialists as Boris Petropavlovsky (launcher developer) and Valentin Artemyev (guide designer). The first combat tests took place in June 1941 near Orsha, where the Katyushas proved their effectiveness against concentrations of enemy equipment and infantry.
Today “Katyusha” is associated with victory in the Great Patriotic War, but its creation was overshadowed by repressions: Langemak was shot in 1938 on false charges of “sabotage,” and Kostikov miraculously escaped arrest. However, their development was a breakthrough - for the first time in the world it was created mobile jet system, capable of striking at a distance of up to 8.5 km with minimal training.
Key figures: who was behind the creation of Katyusha
The main contribution to the development was made by engineering teams RNII (Jet Research Institute) and NII-3. The main architects of the project were:
- 🔧 Andrey Kostikov — project manager, author of the launcher concept. It was he who suggested using truck chassis for system mobility.
- 💡 Georgy Langemak - specialist in jet engines, developed the basics of the projectile
M-13. Repressed in 1937, rehabilitated posthumously. - 📏 Ivan Gwai - Leading designer of projectiles, optimized their ballistic characteristics.
- 🚛 Boris Petropavlovsky - Responsible for the mechanics of launchers, including the guidance system.
Interestingly, prisoners also participated in the development sharashki - secret design bureaus in the Gulag systems. For example, Valentin Glushko (future chief designer of Soviet cosmonautics) worked on jet engines in one of these groups in the 1930s, although he was not directly involved in Katyusha.
It is important to note that the project was interdisciplinary: not only artillerymen worked on it, but also chemists (developing fuel for shells), metallurgists (light alloys for guides), as well as automotive engineers who adapted the chassis ZiS-6 under the weight of the installation.
Technical features: why Katyusha was a breakthrough
The design of the BM-13 combined several innovative solutions:
- Reactive principle: shells
M-13were accelerated by a jet engine, and not by a powder charge, as in traditional artillery. This made it possible to fire from open positions no rollback. - Volley fire: 16 guides ensured the simultaneous launch of all projectiles in 7–10 seconds, covering an area of up to 4 hectares.
- Mobility: the unit was mounted on a chassis ZiS-6 (later on Studebker US6 under Lend-Lease), which made it possible to quickly change positions.
| Parameter | BM-13 (Katyusha) | Traditional artillery (e.g. 122mm howitzer) |
|---|---|---|
| Firing range | 8.5 km | 11–12 km |
| Salvo time | 7–10 seconds | 1–2 shots per minute |
| Damage area | up to 4 hectares | pinpoint lesion |
| Preparing to shoot | 3–5 minutes | 15–30 minutes (deployment) |
The main disadvantage of the Katyusha was low accuracy: shells were scattered over an area of up to 200x100 meters. However, this was compensated psychological effect — the sound of the volley and the density of shelling demoralized the enemy. By the way, the name “Katyusha” appeared unofficially: the soldiers called the installation by markings K on the ammunition (factory code) and a woman’s name in the manner of a song "Katyusha" Matvey Blanter.
To distinguish the original BM-13 from later modifications (for example, BM-8 or BM-31), pay attention to the number of guides: the Katyusha always has 16 of them, and the caliber of the shells is 132 mm.
Evolution of the project: from drawings to mass production
The development of Katyusha took place in several stages:
- 📅 1920–1930s: theoretical studies of rocket artillery in Gas Dynamic Laboratory (GDL) and RNII. The first experimental projectiles were created.
- 🔨 1937–1938: the arrests of key specialists (Langemak, Kleymenov) slowed down the work, but Kostikov continued the project in secrecy.
- 🚀 1939–1940: successful testing of prototypes at the test site in Shchurovsky (near Moscow). A design with 16 guides has been approved.
- ⚡ June 1941: urgent deployment of production to Voronezh plant named after. Comintern and Moscow "Compressor". The first combat salvoes were fired on July 14, 1941 near Orsha.
Production was complicated by a shortage of materials: the guides were made from aviation steel, and the chassis was taken from truck conveyors. By the end of 1941, about 40 units were produced, by 1945 - more than 10 thousand. I wonder what German engineers tried to copy "Katyusha", but their analogues (Nebelwerfer) were inferior in range and reliability.
The myth of artisanal production
The common misconception that Katyushas were assembled “on the knee” from scrap materials is incorrect. In fact, production was strictly standardized: for example, guides were made on machines with an accuracy of 0.1 mm, and projectiles underwent strict quality control. “Craftsmanship” refers only to field repairs, when soldiers adapted installations for captured chassis or improvised with mounts.
The role of "Katyusha" in the Great Patriotic War
The system received a baptism of fire July 14, 1941 near Orsha, where the captain's battery Ivan Flerov fired a salvo at a concentration of German equipment. The effect exceeded expectations: in 15 seconds, up to 20 armored vehicles and up to an infantry battalion were destroyed. After this, Katyushas became a symbol of Soviet resistance.
Key operations involving BM-13:
- 🏆 Battle for Moscow (1941): used for counterattacks under Naro-Fominsk and Klinsky directions.
- 🔥 Battle of Stalingrad (1942–1943): salvoes of Katyushas suppressed German positions in the area Mamayev Kurgan.
- 💥 Kursk Bulge (1943): massive use in Operation Kutuzov to destroy the defensive lines of the Wehrmacht.
- 🚁 Berlin operation (1945): used to storm the city, including shelling Reichstag.
The Germans nicknamed it "Katyusha" "Stalin's organ" for the characteristic sound of a salvo and destructive power. Soviet soldiers valued her for ease of maintenance: a crew of 5 people could fire a salvo and change position in 3-5 minutes, while traditional artillery took much longer.
The main advantage of the Katyusha is its combination of mobility and firepower. It could strike areas where targeted hits were ineffective (for example, against trenches or columns of equipment).
Myths and legends: what’s wrong with popular stories about “Katyusha”
There are many myths around the Katyusha, some of which are far from reality:
⚠️ Attention: There is a widespread myth that Katyusha was invented by one person - supposedly it was Mikhail Koshkin (creator of the T-34 tank). In fact, Koshkin had nothing to do with the project. The authorship belongs to the RNII team.
- 🚫 “Katyusha was made in a month”: in fact, development has been going on since the 1930s, and in 1941 they only accelerated mass production.
- 🚫 “The shells were unreliable”: the proportion of misfires was less than 1%, which was an excellent indicator for jet technology of that time.
- 🚫 “The Germans copied Katyusha exactly”: them Nebelwerfer had a shorter range (6.5 km) and a complex reloading system.
Another misconception is that “Katyusha” was first in the world reactive system. In fact, similar developments were carried out in Germany (project «Nebelwerfer» since 1933) and USA (experiments with rocket artillery in the 1920s). However, it was the Soviet system that became the first mass and mobile, which provided her advantage.
Modern heritage: where you can see Katyusha today
Today, the original BM-13s are preserved as museum exhibits and monuments. Where you can see them:
- 🏛️ Central Museum of the Armed Forces (Moscow): One of the first mass-produced installations is on display.
- 🎖️ Victory Museum on Poklonnaya Hill: reconstruction of a combat position with a Katyusha.
- 🌍 Memorial "Brest Fortress" (Belarus): installation as a symbol of defense in 1941.
- 🚜 Military-technical museums in Verkhnyaya Pyshma and Kubinka: functional instances.
In addition, "Katyusha" became the prototype for modern MLRS, such as "Grad", "Hurricane" and "Tornado". The principle of multiple rocket launchers and mobility remains relevant: for example, in "Tornado-S" (modification of the Grad) uses the same concept, but with digital guidance and increased range (up to 120 km).
☑️ How to distinguish the original BM-13 from a replica
FAQ: answers to frequently asked questions about Katyusha
Why wasn't Katyusha used at the beginning of the war?
The first production units were ready only by July 1941. Before this, only prototypes existed, and mass production began after the evacuation of factories to the east (for example, in Sverdlovsk). In addition, the Soviet command was initially skeptical about jet weapons as “exotic”.
How many shells could a Katyusha fire in one salvo?
The standard BM-13 had 16 guides and fired all projectiles M-13 in 7–10 seconds. Reloading took 5–7 minutes (depending on the preparation of the crew). Later modifications, e.g. BM-31-12, had 12 guides for projectiles M-31 caliber 300 mm.
Is it true that Katyusha could be installed on any truck?
Theoretically, yes, but in practice only chassis with sufficient load capacity were used: ZiS-6 (6×4), Studebker US6 (under Lend-Lease), and later - ZiS-151. For example, installation attempts on GAZ-AA led to capsizing due to the weight of the installation (about 2 tons).
What was the maximum speed of the Katyusha?
The speed depended on the chassis: on ZiS-6 - up to 55 km/h on the highway, on Studebker US6 - up to 70 km/h. However, due to the weight of the installation and poor roads, the actual speed of movement rarely exceeded 30–40 km/h.
Why wasn’t Katyusha exported to other countries?
During the war, the USSR did not supply Katyushas to its allies in the anti-Hitler coalition due to the secrecy of the technology. The first export deliveries of jet systems (more modern ones, for example BM-21 "Grad") began only in the 1960s and 1970s in the Warsaw Pact countries and the Middle East.
