Ukrainian forces struck the Yenisei radar station, a component of Russia's advanced S-500 air defense system, in Russian-occupied Crimea, Ukraine's military intelligence (HUR) confirmed on Aug. 8.
The agency's drones attacked multiple high-value Russian military targets in occupied Crimea, including a fast assault landing craft and three radar stations, the day prior.
During a "recent" operation, military units from the "Prymary (Ghosts in English)" division, operating under HUR, struck "one of the most valuable radar stations in Russia's arsenal," the 98L6 Yenisei, according to a statement that did not specify the date of the attack.
The Yenisei radar station is used not only in Russia's S-500 air defense system but also as part of the S-400 system, HUR said.
The agency described the Ukrainian strike as a "significant blow" to the capabilities of Russian forces in occupied Crimea.
