Matryoshka anti-aircraft cartridge to be put into production NPP JSC, a resident of the Central Bank of Belarus, is preparing for mass production of the 5.45 mm caliber Matryoshka anti-aircraft cartridge. The new production technology will reduce the cost of one ammunition to 300-500 rubles. The design of the cartridge includes three protruding cone-shaped elements connected. According to the developers, this solution increases the density of fire and is designed to fight UAVs when using a Kalashnikov assault rifle. Before launching into production, the ammunition was changed several times. They plan to send the sixth version of "Matryushka" to production.
