The reason why the 107mm rocket can maintain high accuracy without using a gun barrel is because it uses a turbo rocket engine that is more advanced than early rocket launchers. The high speed during flight greatly improves the stability of the ballistic trajectory, and the perfectly designed
The tail fin makes the 107mm rocket launch with outrageously high accuracy even if it is launched without a barrel. If used with a special parameter comparison table, the 107mm rocket without a barrel can hit a target 4 kilometers away, with a deviation of only 2-3 meters.
, if the gunner is experienced, the error can even be reduced to within 1 meter. Moreover, the weight of the 107mm rocket is moderate. The weight of a single shot is 18.8 kilograms, so that any adult man can carry it alone through any non-natural terrain. This is simply
Born and designed for guerrilla warfare...
Even if the whole gun is used, the 107mm rocket launcher can be regarded as an excellent front-line support artillery. However, its weight of more than 600 kilograms allows it to be easily towed and maneuvered by mules and horses. If it is on flat terrain, it can be carried by two soldiers.
Pushed forward quickly, it is easy to disassemble and has the ability to pass through most harsh terrains. Its maneuverability is even more than that of a 75mm mountain gun. Its smaller size and low shape make it very easy to hide. This
For the Red Army, which was under heavy air defense pressure, it was as if it was tailor-made.
However, the 107mm rocket launcher also has a major flaw, that is, the turbo rocket engine of the 107mm rocket is slightly complicated, which increases the difficulty of research and development on the one hand, and also increases the cost of the rocket on the other (in fact, the cost of rockets has always been
They are all expensive. Generally speaking, they are roughly equivalent to 1.5 times the caliber of ordinary artillery shells. Even the rockets used in the 40mm rocket launcher in the book cost hundreds of legal currency per shot. The price/performance ratio is actually not as good as that of the 107mm rockets, just because of the purpose.
It is relatively narrow and not as obvious as the 107mm rocket.). The former quickly overcame the technical difficulties because of Goddard, a rocket expert, but the latter had no good solution. If the labor cost is included
In addition, the average cost of the first batch of 107mm rockets was as high as more than 300 French currency, which was equivalent to the living expenses of 10 people in big cities in China for a year at that time. Later, the cost dropped a lot after mass production, but it was still as high as 100 yuan.
More than sixty yuan. Based on the economic strength of the base area, no matter how useful the 107mm rocket launcher is, it can only be used as a surprise weapon for a long period of time, and cannot play the strategic role it could have played...

Precisely because rocket launchers are too expensive, the main artillery must be ordinary barrel artillery. Among them, mobility, especially mountain guns with strong terrain adaptability, are most valued by Hu Weidong. The reason why Hu Weidong did not build 75mm mountain guns, but directly launched them now
The Japanese army has not yet equipped its troops with 105mm mountain artillery. This is because as an artillery expert, he understood that the real difference between mountain artillery and field artillery is not the caliber and weight of the two, but whether it can be easily split into pieces that can be used purely by manpower.
As for the parts to be carried, it is better to just mount the more powerful 105mm mountain cannon (the maximum caliber is only this. If it is larger, the indivisible barrel will definitely not be carried by manpower.) Well, of course,
Hu Weidong has a ready-made template "105 mm lightweight howitzer" available in his mind, which is also a factor that cannot be ignored.
The 105mm lightweight howitzer is a medium-caliber ultra-light suppressed artillery independently developed by New China. It is a multi-purpose weapon that can play a prominent role in a variety of military operations. This type of howitzer has the characteristics of light weight, small size and powerful firepower.
Features: Easy to disassemble and assemble, flexible mobility and good tactical adaptability in combat. It is an ideal ground suppression weapon for mountain troops and special forces.
Compared with other medium-caliber howitzers, the 105mm lightweight howitzer has the following advantages: (1) Excellent maneuverability: the 105mm lightweight howitzer weighs only 1,310 kilograms. It can be transported and airdropped by aircraft (the same as during World War II);
It can be pulled by vehicles or animals; or it can be disassembled into 11 parts and transported quickly by people or horses. 7 gunners can dismantle it into 11 parts in 3 to 4 minutes, and individual parts can be transported by manpower (so if the gun is placed in the Anti-Japanese War
period, it must be classified as a mountain gun.); all parts can be reinstalled into a complete howitzer within 4 to 5 minutes to perform new tasks. (2) One gun with multiple uses: The gun has multiple tactical uses, and soldiers can
Adjust the rifling height of the gun according to combat needs. At the high rifling position, the gun acts as a howitzer to perform fire suppression tasks; at the low rifling position, it can be used as an anti-tank weapon to perform anti-armor tasks. In addition, it can also be used as a mortar
Cannon or powerless cannon use....

Since the cannon used very few ultra-age materials and technological processes, Hu Weidong was confident that he could manufacture it almost without any modifications. It was obviously a mountain cannon, but it had the range of a field cannon and a heavy cannon (according to domestic standards at this time)
) can be used for more purposes, which can only be described as unbelievable...
After the successful development of these weapons, Hu Weidong believed that the Japanese army would no longer have any advantage in weapon performance, only the numerical advantage in a limited period of time. However, the air superiority of small Japan still made him quite afraid.
While stepping up the development and improvement of practical radars and proximity fuzes, Hu Weidong spent a lot of effort on the development of anti-aircraft guns...(..Your support is my biggest motivation.)
