CCTV's first large-scale popular science program broadcasts a section on the contents of China's tank armor-piercing projectiles: China's 59-type tank armor-piercing projectile instantly penetrates ten layers of steel plates, with a total wear depth of 1500mm. Therefore, for the most advanced 99A tanks in China, which are superior to the performance of the 59-2 tank, if it is a 125mm tungsten alloy armor-piercing projectile, the piercing depth should be greater than 1500mm.
Military experts said that China's strength in the field of armor-piercing has reached the world's advanced level! So, how powerful is our main battle tank? Can the 99A tank launch a tungsten alloy armor-piercing projectile with a penetration depth of 1500mm?
As is well known, in general, the unit indicating the depth of piercing of armor piercing is - mm / mm. However, many military enthusiasts should also know that the M829A3 depleted uranium alloy armor-piercing project equipped with the US M1A2 tank has been occupying the world's strongest wear-through. It is known as the "king of the active service". Deep can reach about 720-770mm. However, there should be some knowledge of depleted uranium alloys. Although, compared with tungsten alloy armor-piercing projectiles, depleted uranium alloy armor-piercing projectiles probably have a depth advantage of more than 10%, but at the same time, they are caused once. Damage and secondary killing can not be ignored!

How come a injury, a second kill? Against the enemy? To yourself? During the war, both the enemy and the combatants and the theater personnel have an impact! Because uranium is very reactive, it reacts violently with oxygen in high heat. Therefore, the depleted uranium alloy armor-piercing projectiles often wear more scorching flames and radioactive dust after piercing the armor. The most direct result is an injury that is caused or irreversible to personnel in the armored vehicle. And no matter which side of the wounded inhaled these radioactive dusts, it will cause extremely long and serious radiation in the body, which is a much more serious secondary killing than the tungsten alloy armor-piercing projectile. Moreover, the range of firepower that is deeply affected by depleted uranium artillery fire is even larger. It is not only the charcoal of life, but also the continuous chemical pollution problem. There is no humanitarian point!
Therefore, the whole world has given up using depleted uranium bombs! Today, the United States is the only country in the world that uses depleted uranium. This is not a good color, it is not worth boasting, but it should be a good idea. Therefore, for China using tungsten alloy armor-piercing projectiles, it is not excessively boastful. However, under the self-sharp effect, the tungsten alloy armor-piercing projectile can still achieve good results, which is a very proud thing!
Type 99A Tank Picture
Previously, CCTV's first large-scale popular science program broadcasted a section on the contents of China's tank armor-piercing projectile: China's 59-type tank armor piercing project instantly penetrated ten layers of steel plates (each layer thickness is about 15cm, or 1500mm). It is really shocking! Among them, the tank used in this experiment is a relatively old and improved 59-2 tank in China, using a 105mm line gun. In other words, this test only represents the level of China's 105mm armor-piercing projectile.
In terms of fire performance, the 59-2 tank is still a huge generation difference compared with the most advanced 99A tank in China (using a 125mm main gun). There are still gaps between the ten steel plates in this experiment, and there is bound to be energy loss. The true armor thickness of the 59-2 tank launch armor-piercing projectile must be greater than 1500mm. Therefore, if the 99A tank, which is the king of China's land warfare, launches a 125mm tungsten alloy armor-piercing projectile, its wearing depth should be greater than 1500mm.
In any case, in order to achieve a large armor piercing depth and high armor-piercing armor-piercing projectile, the tungsten alloy for armor-piercing projectile needs to meet the following conditions: high strength, good shape, toughness, easy to process into a large length, large length-to-fine ratio core. , better end ballistic power, acceptable cost. In the course of research, researchers in China found that if the adiabatic shear rate is too high, the "self-sharpness" problem cannot be achieved. Ultra-fine grain tungsten alloy can effectively reduce the adiabatic shear rate of tungsten alloy, so ultra-fine grain tungsten alloy has become a research hotspot of tungsten alloy armor-piercing projectile. Of course, the large slenderness ratio ultra-fine grain tungsten alloy can also be applied to all kinds of anti-tank gun armor-piercing projectiles, high-speed kinetic energy missiles, and tungsten arrow bombs in the tactical missile warhead. As for the current situation, can the M1 tank equipped with depleted uranium armor hold the frontal strike of the 99A tank tungsten alloy armor-piercing projectile? What do you think?
