The near-anti-aircraft is a short-range defensive weapon. It is mainly used to intercept anti-ship missiles and rockets, missiles or aircraft that attack our ships. It can also shoot at sea targets. It is the last barrier of military defense. Therefore, it is necessary to kill and completely destroy the weapons and equipment. Otherwise, they will still cause damage to our army by virtue of superior inertia and kinetic energy. Based on this situation, it is necessary to use the most lethal projectiles. China's near-anti-guns generally use tungsten alloy armor-piercing projectiles. Some people may ask: Why not use depleted uranium bombs, high-explosive bombs, training bombs, steel core bombs, grenades and other shells, and only have a special liking for expensive tungsten alloy armor-piercing bullets?

The near-anti-aircraft gun has a strong anti-cruise missile and low-altitude aircraft capability. It is generally equipped on the aircraft carrier and is also equipped on various destroyers and frigates of our army. Its caliber is small, the range is close, and it has the characteristics of high power, fast response, high hit accuracy, many locking targets, and good reliability.

The so-called near-anti-gun is a cannon with a close range and a defensive ding. The bombardment of high-explosive bombs and steel core bombs is too low. Even if the weapons and equipment are destroyed, the wreckage will hit our warships due to inertia and kinetic energy. Broken enemy weapons and equipment, to avoid the shells that continue to collide with the wreckage.

Tungsten alloy armor-piercing projectile is a kind of high-specificity tungsten alloy product with military significance. It is an excellent kinetic energy armor-piercing projectile developed after the 1970s. It adopts the principle of shelling and high-density tungsten alloy. It penetrates the armored projectile with the strength, weight and speed of the core. It has large initial kinetic energy, high initial velocity, good vertical armor piercing performance, large direct shooting distance, short flight time and shooting accuracy. High-level advantages, and can hardly and effectively deal with multiple targets for rapid movement and a fatal blow to armor.

The tungsten alloy armor-piercing projectile is mainly composed of a hood, a core, an elastic body and a tracer. It is a projectile that relies on the kinetic energy of the tungsten alloy core to penetrate the armor and destroy the target. The core is made of high-density tungsten alloy and is the main body of the armor-piercing projectile. Its diameter is small, so the shape of the armor-piercing projectile can be designed to be streamlined. The tungsten alloy armor-piercing projectile also relies on its core to penetrate the armor and destroy the target. The projectile is made of low carbon steel or aluminum alloy and is mainly used to support the core. There is a guide belt on it to ensure the stability of the projectile rotation. The tungsten alloy core is fixed in the middle of the projectile. When the armor is hit, the body will burst instantly and then pierce. Because tungsten alloy has high density, high hardness, good thermal stability, and no compression resistance, it does not deform substantially during piercing. After breaking through the armor, high-speed splashing of armor debris, armor-piercing projectile fragments, etc. kills the personnel in the armor target and destroys the equipment.
