 Ukrainians use Hymars to destroy Russian S-400 air defence command post. According to images posted on the Special Curson CAT Twitter account on May 30, 2023, Ukrainian soldiers using US-supplied Hymars multiple launch rocket systems have for the first time destroyed a Russian 55K-6E command post of an S-400 Triumph air defence missile system. The S-400 Triumph is Russia's most advanced operational air defence system according to Army recognition. One of the key components is the 9-1N-6E, Big Bird Acquisition and Battle Management radar. The radar system serves as the eyes of the S-400 scanning the airspace for potential threats within a range of several hundred kilometres. It detects and tracks multiple targets simultaneously including aircraft, drones and ballistic missiles. The 55K-6E command post is another crucial part of the system. This is where all the data from the radar units is analysed and decisions are made about how to respond to the threat. The command post ensures that the system operates coherently and coordinates the launch of the missiles. Speaking of missiles, the S-400 system utilises several different types each designed for a specific range and type of target. Finally, the system includes logistical support vehicles.
