Although it was the first "Katyusha" of the Soviet army to be used in modern practical combat, the ancient Chinese used this weapon to war very early. As early as 969 AD, my country made the world's first gunpowder-powered rocket. At that time, the rocket was very simple, tied the cartridge to the arrow, ignited the cartridge, and sprayed the gunpowder gas backwards, using the reaction force of the jet to push the arrow forward. According to this principle, during the Song Dynasty, 32 rockets were made with volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of volleys of

In 1805, Congliff used new gunpowder to create a practical rocket, weighing 14.5 kilograms, arrows 1.06 meters long and 0.1 meters in diameter, and equipped with a 4.6-meter-long balance rod with a range of up to 1,800 meters. This rocket made outstanding achievements in the British war to defeat Napoleon's army. Due to Congliff's contribution to the rocket, the British government awarded him the title in 1814 and was elected as a member of parliament in 1817. However, Congliff rockets had not yet solved the guidance and control problems and had poor accuracy. In 1844, William Hall of the United Kingdom invented a spin stabilizer and used to improve the Congliff rocket. Although all these rockets were very simple and not widely used, their appearance played the overture for the birth of the modern rocket.

The rocket developed by Congrif has improved in terms of range, accuracy and stability methods, and its performance has almost reached the limit of gunpowder rockets. Due to its huge lethality, countries have begun to pay attention to the research and use of rockets. Since then, another major advancement of war rockets is the improvement of stability. In the mid-19th century, British inventor William Hale installed three inclined stable spiral plates on the tail of the rocket. When the rocket was launched, the rocket itself rotated due to the aerodynamic effect, thus achieving stability. Until World War II, the development of gunpowder rockets had been improved. Its basic structure is a rocket launcher equipped with gunpowder, with launching drugs as propellant in the middle, high-explosive and fuses on the head, and a spout at the tail. In addition, the tail stabilized wings used to stabilize, and a launcher or launcher was used on the launch device. The more famous is the Soviet rocket launcher - Katyusha.

In 1939, the former Soviet Union made the B, M13 rocket launcher, commonly known as the "Katyusha" rocket launcher. This rocket launcher uses a multi-rail directional device, which can fire 16 rockets with a 132mm diameter in one volley. The bomb has a speed of 70 meters/sec, a maximum speed of 355 meters/sec, and a maximum range of 8.5 kilometers. It can launch all 16 rockets in 7 to 10 seconds, and it takes about 5 to 10 minutes to load it again. An artillery battalion composed of 18 Bmiii3 rocket launchers can fire 288 rockets in one volley, which can effectively kill the enemy. On July 14, 1941, the former Soviet army used this powerful weapon of destruction on the battlefield for the first time.

China developed rocket launchers much later than the Soviet Union, but earlier than the West expected. In 1948, the People's Liberation Army expert Zhong Lin formed a rocket technology room in Hebei and began to develop A3 6-barrel 102mm field rocket launcher, and then transferred to the 52 factory to continue its development. On the third day of the birth of New China, the gun was reported and performed in the Lugou Bridge area of ​​Beijing, and Commander-in-Chief Zhu De praised it. In 1951, China successfully developed the Type 427 and Type 488 102mm rockets with a maximum range of 5 kilometers. Since China later unified the use of Soviet-made equipment, which is the so-called "standardization", the field rocket launcher was not included in the equipment sequence and was transferred to the Vietnamese army, but it gave the Chinese rocket launcher a good start.

China Type 63 107mm rocket launcher:

The Type 63 107mm 12-pipe rocket launcher was developed in 1961, designed and finalized in 1963 and put into mass production, and equipped the troops in large quantities.

In fact, the 107mm rocket launcher is a highly user-friendly fine artillery, and various parameters have been repeatedly optimized. First of all, the rocket is designed to be 18.8 kilograms, and one person can carry one, which can also be withstood long-distance marching in complex terrain. The 107mm rocket launcher is not only light in total, but also can be quickly decomposed and combined. The weight of a single component after disassembly does not exceed 30 kilograms. In order to meet the requirements of the human back, the decomposed part has the following characteristics in terms of structural size: the upper part is not the neck (easy to raise the head), the lower part is not the hip (easy to step), the wider part is not the shoulder (easy to pass), and the center of gravity is close to the body (preventing to twist the waist). In addition, it can be said that any rocket launcher in the world can be compared with the 107 rocket launcher.

Unlike the active rockets in the United States and the Soviet Union, the 107mm rockets are stable in flight using turbine rotation. The centerline of the rockets is deflected at a small angle. After the rocket is ignited, the gas pushes the rocket forward while pushing the rockets forward like ordinary rifled guns to ensure the stability of the shells during flight. If necessary, the 107mm shells can be placed directly on the ground without a launch device. After aiming, they can be launched with several ordinary batteries and two ordinary wires or wires. Generally speaking, the target distance of 1000-1500 meters is better when firing easily. What's more, it was reported that the Afghans used stones to smash the back cover of the 107mm rockets, placed in a row on the ground, and then directly ignite the fire to launch.

The rocket launcher appeared in the article only began to test equipment after a complete set of processing machinery and mature launchers appeared. This article will strive to be rigorous in conception, because it is superficial, except for the relevant background, other things will be different from history. By the way, Lanshan is based on the background of the Taihang Mountains, and all the mineral resources in it are real and there is no fiction. If you are interested, you can check it out. As for the chief engineer of the steel plant, it is taken from the legendary life of a technical engineer of a modern large steel plant. He left Beijing before the outbreak of the Anti-Japanese War, and later actively participated in industrial saving of the country in the Kuomintang-controlled area and served as the chief engineer of the steel plant. Until he returned to Beijing after liberation, he continued to serve as the technical work of a large steel plant.

The rocket launcher that appears in the article is completely possible from a technical perspective. Of course, its power may not be as advanced as modern times, but I believe this will change the way of war in the past with Xiaomi and rifles. Those who like real history can read the war history. This article is thinking about a war that does not rely on major powers of various countries to win this war independently. See how our country will be worse than the Japanese if it is planned reasonably. The Japanese are accustomed to plagiarizing scientific and technological achievements and returning them to their own. This time, let me give it back.
