Media coming in from Crimea show explosions and fire in Dzhankoi, Crimea. Secondary explosions appear to be visible in the video, indicating that at the least, TELs for an air defense system may have been struck.
Previous analysis conducted in March did reveal an S-400 in the location of the explosions.
The Ukrainian GUR released more information about the attack on Dzhankoy air base in occupied Crimea, which Ukraine struck, reportedly with ATACMS.
4 S-400 launchers, 3 radar stations, an air defense control center and airspace surveillance equipment (FUNDAMENT-M) were destroyed or critically damaged.
The number of damaged or destroyed Russian aviation facilities and the number of casualties among Russian army personnel is being clarified, they add.

Shows location of new S-400 site. I'm skeptical of it being a decoy because of the nature of the fire and explosions.
