Tungsten alloy rotationally stable dehulling armor piercing has a large proportion, high hardness, the power of wear armor, high hit rate. It uses a decanted structure, reducing air resistance and slowing down the speed attenuation of the flight part on the outer ballistic. At the same time, the small density of aluminum alloy cartridge is used to reduce the mass of the projectile, so that the initial velocity of the projectile can be improved, so as to improve the long-distance armor penetration ability.
As the length and diameter ratio of the tungsten alloy rotationally stable dehulling armor piercing is limited by the flight stability, its power is difficult to be further improved, and it is unable to deal with modern armor such as large normal angle thick armor and composite armor of modern tanks. Therefore, the tungsten alloy tail fin stabilizer shell piercing ammunition was developed and equipped on the large-bore barrel gun.
