The Ukrainian military intelligence agency, HUR, has disclosed that Russia has been utilizing an upgraded version of its Geran-4 drone, equipped with advanced navigation and targeting systems. According to the HUR, the drone features a small magnetic sensor from American manufacturer PNI Sensor, which enables the device to detect changes in position and correct navigation errors. This revelation highlights the ongoing presence of foreign components in Russian military technology.
The HUR has previously reported the presence of American components in Russian arms, with a total of 5,816 foreign components identified in 202 Russian systems as of August 2026. These components are sourced from Europe, Asia, and North America through "grey" circuits and third-party countries, despite international sanctions. The use of foreign components in Russian military equipment has been a consistent concern for Ukrainian authorities.
The upgraded Geran-4 drone features a PNI5GA magneto-inductive magnetometer integrated into a new module, which works in conjunction with the SADRA inertial navigation system to correct gyroscope drift. Additionally, the drone is equipped with the "Susanin" autonomous navigation system, which compares recorded images with reference images in its memory to maintain its trajectory to the target. This allows the drone to operate without relying on satellite signals.
The modernized Geran-4 drone boasts several key upgrades, including a new warhead designed to damage bridges and power line supports. The drone's engine, previously sourced from Chinese manufacturer Telefly, has been replaced with a Russian equivalent produced in Alabouga. However, the electronic components remain largely identical to those used in previous Geran drones.
Ukrainian intelligence has noted that some components used in Russian drones are remarkably recent, with American parts manufactured as late as late 2025 found in Shahed drones used in late March 2026. This suggests that Russia continues to access foreign components despite international sanctions. The HUR's findings highlight the complexities of Russia's military supply chain and its reliance on foreign technology.
The use of foreign components in Russian military equipment has significant implications for international relations and the ongoing conflict in Ukraine. The Ukrainian government has repeatedly raised concerns about the presence of foreign parts in Russian arms, citing the potential risks to national security. The international community has imposed sanctions on Russia in an effort to restrict its access to foreign technology.
The upgraded Geran-4 drone represents a notable advancement in Russia's military capabilities, with enhanced navigation and targeting systems. However, the reliance on foreign components raises questions about the long-term sustainability of these upgrades. As the conflict in Ukraine continues, the use of foreign technology in Russian military equipment is likely to remain a contentious issue.
