 Ukrainian defenders destroyed an expensive Russian S-400 air defense system. Ukrainian defenders destroyed the Russian S-400 Triumph air defense system consisting of a 5P85 SM-2-01 launcher and a 9-2N6E radar. As Ukrainian military expert Alexander Kovalenko noted, according to verified data, this is already the second S-400 air defense system destroyed. It is also important to understand that this air defense system is located deep in the rear, he added. S-400 Triumph is a Russian long range and medium range anti-aircraft missile system. S-400 is designed to destroy all modern and promising means of aerospace attack. The contract value of one division of four vehicles of the S-400 anti-aircraft missile system is about $1,250,000,000 or more than 97 billion rubles. At the end of last year, Belarus announced that the first S-400 and Iskandar complexes received from the Russian Federation were put on combat duty. Ukrainian military expert Oleg Zdanov predicted that there was a threat of S-400 missiles from the territory of Belarus in the Kiev region in response to the counter-offensive of Ukrainian forces. In particular, the total combat losses of the Russian army from February 24, 2022 to July 11, 2023 approximately amounted to 414 air defense systems.
