 Russian stealth kamikaze drone undergoes tests in Ukraine operation. A loitering kamikaze quadcopter with a low radar signature is undergoing tests in the zone of the special military operation in Ukraine. Vitaly Dolgov, head of the Laboratory of External Piloting and UAV operation in the Kartsev Research Institute of Computer Systems, told TAS. The loitering kamikaze has been sent for tests to the zone of the special military operation and currently two of our drones are being employed there. The drone has proven its worth. The drone's hull has been created using special radar absorbing material that makes it almost invisible to enemy electronic warfare systems. The coating is added to composite materials in making the drone's frames. It absorbs up to 50% of radar electromagnetic emissions, the researcher said. The latest drone is capable of carrying a 4kg payload, he specified. The loitering kamikaze has two objectives. It can be used as a loitering munition and can deliver and drop explosives. The drone can easily carry a payload of 4kg to a distance of 10km. We keep upgrading the aerial vehicle and are currently working on the system of dropping as many as 6 munitions. Dolgov said, the Kartsev Research Institute earlier unveiled a grumb mobile folding quadcopter designed to ferret out targets and drop munitions.
