A friend who is familiar with domestic light weapons said that due to the large base of domestic equipment, domestic light weapons often need a lot of equipment after completion, and I know it is very difficult. This will also lead to the success or failure of the machine gun model, which is considered to be related to whether it can really meet the requirements of 10 years or even longer equipment cycle.
Domestic light machine guns, especially domestic light machine guns, have also gone through many detours in the development process. At this point, QJB20 1 and the new children's stories basically began to look back, but it was almost 20 years in the middle. Of course, this problem can be traced back to 1980 s and 90 s. The main fire support weapons of local army units are Type 89 12.7 mm heavy machine guns and Type 88 5.8 mm general-purpose aircraft, which have not been approved yet.
The caliber of this weapon is large enough, but the machine gun group occupies too many facilities, and the problem of ammunition puller is also obvious. When carrying, there are three ammunition boxes behind the gunner, and there are 1 machine guns. There are only 200 rounds of ammunition in total, which can be changed into low ammunition when loaded high.
The reason why this happens is that the relevant domestic forces have accepted the so-called "medium caliber uselessness theory", and accordingly the development of medium caliber general machine guns and sniper rifles has completely stopped. This transformation has produced a new generation of small caliber weapons, including automatic rifles, general-purpose aircraft, passenger planes and sniper rifles.
The advantages and disadvantages of small-caliber ammunition are not repeated here, but only one point is mentioned. Many military fans will suggest a specific test of Type 95 rifle to illustrate the benefits of small caliber bullets. But in fact, the biggest problem with small caliber is that it can't meet the requirements of long-range shooting, but it shortens the combat distance of light weapons and will be injured in actual combat. 7.6239 medium power bomb is the same, except that 7.6254R/5 1 full power bomb is suitable for small teams to support firepower.
The initiator of small caliber weapons, the "medium caliber uselessness theory" was developed by the United States. In 1970s and 1980s, some light weapons theorists in the United States, Soviet Union and Europe believed that 12.7mm machine gun did not need to be used as a medium caliber light weapon to replace the 7.62mm infantry machine gun. Based on this situation, infantry can use smaller caliber machine guns, carry more ammunition, gain better maneuverability and facilitate rapid breakthrough.
According to a large amount of information published now, this military theory may have been deliberately "established" by the United States in order to influence the development of light weapons in the Soviet Union. In fact, the Soviet Union was not deceived, and this theory was continued by the Soviet Union, because China and the Soviet Union were in a hostile state and both sides were in danger of nuclear war. Affect us. But we accepted the theory that the Soviet Union did not accept. Because of learning from the west, the research and development of medium caliber weapons completely stopped.
On the other hand, it is clearly recorded in Liu Xuechang's paper "The History of Guns" that the United States and the Soviet Union did not reload small-caliber weapons with him. China clearly stipulates that medium-sized machine guns cannot use small caliber. Unfortunately, the state does not attach importance to it.
Until 20 17, the United States proposed a new machine gun scheme to the US military. The M240L modified machine gun used temporarily was actually a medium caliber MG5 machine gun installed in Germany in 20 14. However, after many practical tests in the 1990s, there are many shortcomings in small caliber general machine guns. It can be said that the Soviet Union and the United States, which advocated medium caliber, actually did not abolish medium caliber, but gave up medium caliber after learning from the Soviet Union and the United States.
Of course, the situation has changed a lot. Even the latest class machine gun QJB20 1 has a caliber of 5.8mm, but if we insist on using ammunition, we can still solve the problem of insufficient long-range shooting to some extent. At the same time, QJB20 1 has been completely lightweight, and even the same 5.8mm bullet will have a loading capacity of more than 1000 rounds.
Another 7.62 mm general-purpose machine gun will completely reverse the trend of small-caliber machine guns started in the 1980s. Here, I want to emphasize once again that this machine gun is not the firepower of the 7.639 Zhongwei machine gun unit, but a 7.6254R full-power machine gun, not something carried by infantry, but a company-level support firepower of 800,-1200. 7.62 mm is superior to the current 5.8 mm in firepower, suppression level and range, especially when the actual range far exceeds the set highland, which provides a strong guarantee in infantry operations.
Generally speaking, from 1980s to 1990s, the international situation has undergone earth-shaking changes. During this period, not only our country, but also all countries in the world were in turmoil, and armaments were adjusted frequently. It was not until the 1990s that the country entered a period of relative peace, and it was inevitable that the development direction of light weapons would deviate.
With the change of the overall situation today, the practicality, attack ability and firepower level of light weapons have become more important, and we also believe that this will be realized. Get rid of the shackles of the past, create products that meet the needs, and realize the new situation of domestic light weapons in line with international standards.
