Russian S-400 System's Command Post Destroyed by Rocket Fired from HIMARS

A command post of the Russian S-400 air defense system (ADS) was destroyed in mid-May during an attack on a temporary weapons storage facility in the Kherson region of Ukraine
A hit made by a HIMARS rocket strike destroyed the Russian 55K6E command and control center of the S-400 air defense system.
A pro-Ukrainian Telegram channel Dosye Shpiona released pictures of the hit. However, there is no information regarding the missile launch vehicle which should have been nearby.
Several photos of the alleged hit have been published on social media.
In addition, the S-400 is almost always guarded by the Pantsir-S short range air defense system which is intended to shoot at missiles, helicopters and drones which may come to attack S-400.
The Ukrainian air force has not confirmed the hit at the time of writing.
