TsNIItochmash developed an armor-piercing cartridge for silent shooting

The Central Scientific Research Institute of Precision Engineering (TSNIITOCHMASH), part of Rostec, has developed a new 9 mm caliber armor-piercing cartridge for silent shooting. This was reported by the press service of the state corporation.


The new cartridge was developed as part of the development work of the Boa constrictor to create the pistol complex of the same name. Despite the noiseless and flameless firing, the new ammunition is capable of penetrating bulletproof vests of the second protection class.

Previously, ammunition for silent shooting could not penetrate body armor of the 2nd class, since the speed of the bullet was insufficient for this (200-300 m / s). At the same time, bullets capable of breaking through a bulletproof vest of this class fly at a speed of more than 400 m / s and are not suitable for silent shooting.

According to the developers, a combination of noiselessness and armor-piercing was achieved by increasing the mass of the bullet cartridge and adding a cutting edge of two flat faces to the front end of its core. Thus, the new cartridge at a relatively low bullet speed has increased armor penetration.

The Russian pistol Udav was developed at TsNIITochmash for the army and the Ministry of Internal Affairs. Its dimensions: length 206 mm, height 145 mm, width 36 mm. The equipped weight of the pistol is 980 g. The pistol magazine holds 18 rounds of 9x21 mm caliber.

      And when they could not, or did not want to? So to speak. "Can when necessary." In TSNIITOCHMASH, developed ammunition, probably for all occasions. I suspect that for many, we will not find out for a long time.

        They are the most. The noiselessness is relative, but nonetheless surprising. T.N. "cats" have already sulked. Do not buzz. Wonder who stayed. :)

        So, "noiselessness" here is implied, most likely, relative! And from the description it’s clear, due to which, having “preserved” the relatively low speed of the bullet, they increased armor penetration ...

        In fact, there are two types of them 7N42 and 7U4 with a reduced bullet speed for silent shooting.

    At one time, the CP-1 pistol (ATP, "Vector" and read the names) created under the 9 x 21 cartridge was not widely used just because of the high cost of the cartridge used. I would like to believe that this problem (the high cost of ammunition) has been solved!

    Such forms were written in the article Vedernikov Yu.A., Khudyakov Yu.S. "Search for rational forms of spatial penetrators", Izvestiya SB SSSR, series of technical sciences, 1983, N 8, issue 3.

    Holes without too much noise can be made with crowbars.

      There will be a noise when you drop it on the leg.
