Foreword:
In the US military decided to purchase 5000 8After the 6-mm medium-caliber machine gun, the Chinese new generation 12The 7mm lightweight large-caliber machine gun was also unveiled in a low-key manner. Both China and the United States are pursuing more powerful and lighter infantry with suppressive firepower, but there are differences in development ideas. This article will ** the technical route of these two heavy machine guns, who is superior and who is inferior.
One: 86 mm medium-caliber machine gun.
Before the invention of machine guns, armies of various countries used "skirmishers" formations, and machine guns came into being to deal with this combat formation. With the advent of rapid-fire guns, heavy machine guns had to be constantly reduced in weight in order to increase battlefield mobility. However, the heavy machine guns carried by infantry are difficult to move in difficult terrain such as mountainous terrain, especially in battlefields such as Afghanistan, where soldiers have high loads and slow maneuvers.
The traditional infantry heavy machine guns of the US military are medium-caliber machine guns such as the Maxim and Browning. In the Afghan War, light machine guns became a more suitable choice because infantry often had to engage their opponents at long distances in highland terrain. However, the existing light machine guns had a limited firing range and could not meet the need for long-range suppression.
In order to increase the power, the US military adopted the M2 type 127 mm large-caliber machine gun with powerful long-range suppression. However, the M2HB type 12The 7-mm machine gun weighed 382 kg, which requires a Humvee to handle, limits mobility. Although weight loss has been attempted, the effect of weight loss is limited due to technical limitations.
After continuous attempts, the U.S. military put forward the purchase of new machine guns, requiring the weight of empty guns to be less than 109 kg, launch ratio 7.The 62mm NATO standard bullet is twice as powerful as the Norma-Magnum 0338-inch NM gun cartridges. The difficulty of this requirement was enormous, however, the General Dynamics LWMMG medium machine gun successfully met this need, becoming a machine gun that was both light and capable of suppressing the opponent.
Two: 12 of the People's Liberation Army7 mm large-caliber machine gun.
The machine gun company of the PLA infantry battalion was armed with 762 mm heavy machine guns, but in the Vietnamese self-defense counterattack, the Vietnamese army often used anti-aircraft machine guns to carry out flat fire outside the light range of the infantry, making it difficult for the PLA infantry to return fire. In this context, the first industry began to develop 127 mm large-caliber machine gun, emphasizing weight reduction and flat fire.
89 Formula 12The 7mm heavy machine gun is a success, using aluminum alloy and other materials to reduce weight, and the total weight is only 263 kg, making it the lightest 127 mm heavy machine gun. However, due to the pursuit of weight reduction, the shooting accuracy is poor, and the use of certain ammunition types needs to be avoided as much as possible.
On the basis of lessons learned, the PLA launched a new generation 127 mm lightweight mountain large-caliber machine gun. The machine gun is made of titanium alloy for the bolt, bolt frame, receiver, buttstock, and floating seat parts, and the whole gun weighs only 185 kg, the service life is increased by 1 compared with the 89 type5-2 times. The tripod is made of carbon fiber composite material and weighs only 6 kilograms, maintaining high strength and shock absorption. By improving the muzzle brake and the floating structure of the gun body, the recoil force was successfully reduced by 80%, which significantly improved the problems existing in the previous heavy machine gun.
Conclusion:
The competition between China and the United States in the field of heavy machine guns is starting a new round of military science and technology disputes. Although each has different technical routes and challenges, they are all striving for lighter and more effective infantry suppression firepower. In the future, this will be a high-profile field, and the technological competition between the two countries will also promote the continuous progress of military science and technology.
The article details the technological development and competition between China and the United States in the field of heavy machine guns, and presents their respective research and development directions, challenges and achievements. This triggered me to think deeply about the relationship between military scientific and technological progress, research and development and actual combat application.
First of all, from the perspective of the United States, the article mentions the challenges faced by the U.S. military in the war in Afghanistan, that is, the limited mobility of infantry carrying heavy machine guns in complex terrain such as mountains. The U.S. military's technical response is manifested in reducing the weight of machine guns and increasing the power of firepower. In particular, the LWMMG medium machine gun launched by General Dynamics successfully met the needs of the US military for a lightweight and high-power machine gun. This reflects the flexibility and adaptability of military science and technology in actual combat needs.
Second, the article mentions the threat of flat-fire fire faced by the PLA in Vietnam's self-defense counterattack, which has promoted China's research and development12The direction of the 7-mm large-caliber machine gun. This development shows that lessons learned in the field play a crucial role in promoting the development of armament technology. Through the research and development of new machine guns, the PLA focuses on reducing weight and improving shooting accuracy to better meet the needs of modern and complex battlefields.
In the competition between China and the United States, it is not only a competition of the power and weight of machine guns, but also technological innovation and rapid response to actual combat needs. The technical challenges covered in the article, such as weight reduction and shooting accuracy, reflect the importance of the ability to solve real problems in the competition in the field of science and technology. This is also one of the core challenges in the field of military science and technology, that is, to achieve accurate solutions to realistic combat needs in technological innovation.
Finally, the battle for military technology mentioned in the article is not only a technological competition between the two countries, but also part of the global military power balance. This competition has far-reaching implications for the global arms landscape. The competition between China and the United States in the field of machine guns reflects the unremitting pursuit of military science and technology by all countries in the world, and also highlights the rapid evolution of armament technology.
On the whole, the article not only provides detailed information on the development of heavy machine gun technology between China and the United States, but also triggers in-depth thinking about the competition in military science and technology. This competition is not only a competition of technological level, but also a manifestation of the cognition and response to the form of modern warfare, and it has also shaped a new military pattern on a global scale.
