As part of another drone attack on Crimea, Ukrainian drones hit, m.in example, elements of the S-400 anti-aircraft system, including its most crucial element, i.e. the 92N6E rocket guidance radar. This is the heart of all S-400 battery. The radar guides the rocket at air targets. Without it, the full battery is useless. The second component hit was a mobile power plant (generator) on a trailer and a truck, which supplies electricity to the full complex.
