The bullets under the size 3BM-42 Mango fired a 125 mm smooth tanker gun officially into the Soviet Army staff since 1986 and remained the main energy-penetrating projectile of the Russian Army and many other countries current time.
Structure of piercing bullet 3BM-42 Mango consists of 2 cores (bar piercing) made from high-strength tungsten alloy with serial structure, integrated with ballistic cap and special vibration reduction mechanism to limit impact Destroy the bullet structure too soon before it hits the target.
The barrel tip of Mango 3BM-42 bullets reaches 1,700 m / s, it penetrates 500 mm of homogeneous steel (RHA) after explosive reaction armor (ERA) when fired from a distance of 2,000 m at a contact angle of 0 degrees.
According to calculations when shot from a distance of 2,000 m, at the target collision, the speed of the 3BM-42 Mango bullet is about 1,000 m / s. With a bar length of 570 mm, it will take more than 1 / 2,000 seconds to pass through the outer surface of the reactive armor, too short to detonate the block and knock the rod through.
However, due to the long-established birth of Mango 3BM-42 bullets, it was judged to be somewhat backward, it would be significantly reduced if it encountered the advanced reactive 3rd generation explosive reactors such as Nozh's. Ukraine or Relikt made by Russia.

Before this situation, Tekhmash will officially introduce bullets under size 3BM-44-1 Mango-M at the 2019 Army Exhibition this year, this is the modernized version of 3BM-42 Mango bullets, the ability to penetrate armor Rostec announced a 20% increase.
The 3BM-44-1 Mango-M dynamic ballistic bullet is suitable for all types of integrated automatic reloaders on the old T-90 and T-72 main battle tanks, no need to edit any What details of the load mechanism.
There is a noticeable detail on the newly-produced T-90S / SK or T-90MS and T-90M tanks equipped with a new generation loader, which allows the loading of high-power ballistic bullets with bars For a longer time, to take advantage of this advantage, Russia produced a caliber bullet named Svinets.
This is an advanced bullet with a length of 740 mm and an initial velocity of 1,850 m / s, its kinetic energy is much larger than Mango, able to defeat the most heavily protected tanks.
Two versions of the trans-Svinets include the use of poor uranium cores 3BM-60 Svinets-2 and tungsten carbide core bullets 3BM-59 Svinets-1.
Test results showed that at a distance of 2,000 m and 60 degree angle, 3BM-42 Mango bullets penetrated 230 mm, this figure at 3BM-44-1 Mango-M was 280 mm, while 3BM-60 Svinets-2 up to 300 mm.
New types of new generation kinetic energy bullets to be released under evaluation will help Russian tanks maintain superiority in modern battlefields.
