The second S-400 regiment, or “regimental set,” hasn’t commenced combat duty at Dmitrov after all.
This was supposed to happen on May 15, but didn’t. According to RIA Novosti, a VVS spokesman said the official commencement of combat duty was postponed [again] from July 17 until the last ten days of this month.
The news agency says the ceremony will take place on Peremilovskaya Height, outside Dmitrov.
Newly-minted VVS Main Staff Chief and First Deputy CINC, General-Major Viktor Bondarev said in June that a third S-400 regiment will become operational this fall.
