The Kinzhal was first used in the zone of the special military operation on March 18, 2022, to destroy the underground military arsenal of the Ukrainian Armed Forces in the Ivano-Frankivsk region. The rocket managed to penetrate the concrete walls of the well-fortified underground weapons storage and blow it up.
On March 9, the Kinzhal hit and destroyed a Ukrainian underground bunker located near Lvov at a depth of 120 meters that served as the headquarters of the Ukraine Armed Forces and NATO. Reportedly, the strike killed 200 officers and generals.
In May, the Russian Air Forces knocked out the US-made Patriot air defense system with a Kinzhal missile in Kiev. Footage of the strike appears to indicate that the MIM-104 Patriot fired a whopping 32 missiles to intercept the Kinzhal but missed the target. Eventually, the Russian hypersonic missile smashed the US-made air defense system.
