This is a relatively new Russian development from 2003.
The mine is designed to protect military and civilian facilities from helicopter attacks, to protect areas of the sea coast where helicopter landings are possible, to protect minefields from helicopter demining, to block the runways of enemy airfields, to block places where reserve airfields can be deployed, and to psychologically influence the helicopter pilot in order to force him to fly at high altitudes.
The mine works against low-flying aircraft (aircraft, helicopters, UAVs) moving at speeds up to 100 m/s (360 km/h). The target is hit by a SBE UYa projectile flying towards the target at a distance of up to 150 meters. The target sensor is a combined acoustic-infrared one, with a sensitivity of no more than 0.6 decibels, which allows you to detect and confidently identify the noise of hang glider engines at a distance of 0.6 km, and helicopters at a distance of up to 3.2 km. The noise selection system allows you to distinguish the sound of an airplane or helicopter engine against the background of the noise of ground equipment engines, explosions, and gunfire. If the noise is recognized as the noise of an air target engine, then when the target approaches a distance of less than 1 km, the warhead is turned towards the target and the target's IR sensors (4–6 sensors) are turned on, which determine the exact direction to the target and the distance to it. Recapture of another target at this time is excluded. The combination of simultaneous operation of acoustic and IR sensors excludes the mine's reaction to thermal anti-missile traps fired by the target. When the target enters the impact zone (hemisphere with a radius of 150 meters), the mine is detonated, and the SBE UYA, moving at a speed of about 2500 km/h, hits the target. The target is considered to be a source of sound and IR radiation at the same time (aircraft engine). The charge is aimed at the upper hemisphere of the helicopter (at the engine and blades). If the target has not entered the impact zone, then when it is removed by a distance of more than 1 km, the IR sensors are turned off, and the mine again enters the target waiting state.
The mine is equipped with a remotely activated non-extraction system.
The self-destruction system provides for the self-destruction of the mine after a specified period or when the power supply voltage drops below the operating standard.
The mine is placed on the ground only manually and is stabilized on the ground with the help of four spring-loaded legs. There is also a variant of the mine with remote installation using helicopters.
At the moment, it is unknown, due to the fact that the mine has not yet been launched into production, undergoing test and field trials.
