Yolka

Ukrainian defense advisor Serhii “Flash” Beskrestnov has published technical details of a little-known Russian interceptor drone known as “Yolka.” According to Beskrestnov, the Yolka interceptor operates only during daylight and cannot be used in rainy conditions. Its effective range is approximately 3 kilometers, with a stated speed of up to 200 km/h. The system is designed to function in wind conditions of up to 8 meters per second. “Yolka works only during the day, cannot be used in rain, and is designed for flight at wind speeds up to 8 meters per second,” Beskrestnov said. He added that the drone has no warhead in its baseline configuration and relies on kinetic interception. The system is optimized for engaging targets moving at speeds up to 80 km/h regardless of angle, while faster targets require trajectory and angle adjustments. The drone also shows reduced performance under certain visual conditions. According to the data, it operates poorly in high-contrast cloud cover and bright direct sunlight. If the interceptor loses its target, it climbs to around 50 meters and then glides down. Technical details from the released schematic provide additional insight into the system’s construction. The airframe is built from carbon fiber components, including an 8×100 mm carbon tube and carbon frame elements, along with 3D-printed airframe parts. The structure includes forward wings, side fairings, and multiple aerodynamic surfaces designed for stability and maneuverability. The onboard electronic component base includes several control boards, specifically a charging board, gyro board, Hall sensor board, and a power management unit (PMU), supported by a 30×10 mm 5V cooling fan. These systems handle flight control, stabilization, and power distribution. The optical system consists of interchangeable lenses, including 4.35 mm and 12 mm options, a head-mounted camera board, M12 locking hardware for lenses, and an aluminum camera mount. This configuration suggests a focus on visual tracking and targeting of aerial objects. The propulsion and control group includes Skystars KOKO RS 2275 1950KV motors, Skystars KM60A AM32 electronic speed controllers, and BLUEARROW D0576 HS MG HV servos. The drone uses a set of four iFlight Nazgul 5R V2 propellers and is powered by a Gaoneng GNB2200 6S lithium-polymer battery. The system also integrates a processing module identified as “Igolka,” described as a signal processor with an integrated AI module and machine learning algorithms. This suggests onboard assistance for target tracking or engagement. Russian sources describe the drone as a “very simple and effective means of intercepting unmanned aerial vehicles at short distances,” noting its use in both offensive roles, such as covering infantry from drones, and defensive roles protecting infrastructure, including in urban areas. According to these sources, the drone is manufactured at a facility in Moscow and has been developed in multiple configurations based on battlefield experience. There are two main versions: one without a warhead that performs kinetic interception, and another equipped with a fragmentation warhead weighing 360 grams. Russian sources report that the Yolka system is currently considered one of the more advanced counter-drone solutions in service and has been deployed with high-priority protection units, including elements tasked with securing Russian President Vladimir Putin.
