Fourth battalion of S-400 Triumph air defense missile systems were deployed to Crimea’s Dzhankoy city on Thursday.
According to Russia’s Ministry of Defense, the system is expected to be operational by the end of the year.
The move comes amid heightened tensions between Ukraine and Russia after the Kerch Strait incident.
Crimea received its first S-400 battalion in January 2017 in Feodosia. The other two battalions are located in Sevastopol and Yevpatoria.
