Footage of the assembly and launch of the Russian KUB drone, manufactured by ZALA AERO. The KUB drone is less expensive than the Lancet drone and has been in use since 2022. In the US, it has been dubbed "Ukraine's nightmare." Most often, the drone is used to destroy enemy structures and personnel, and is primarily equipped with a high-explosive fragmentation warhead containing HMX. The drone may already be equipped with a terminal targeting system. The KUB drone is constantly being improved, and its specifications are evolving. Currently, it is known that the KUB drone weighs between 10 and 15 kg, and its flight range already exceeds 50 km. It reaches speeds of up to 130 kilometers per hour and carries a payload of 3 kg. Its flight endurance is 30 minutes, at altitudes of up to 1,000 meters.
