McKenzie noted that the Russian owned and operated S-300V4 and S-400 systems stationed in Syria did not attempt to engage the incoming cruise missiles. “In the attack on Friday night, Russian air defenses were energized,” McKenzie said. “They were scanning, they had a [Beriev A-50] Mainstay air defense aircraft up. They did not choose to engage, so I can‘t speculate about why they did or didn‘t do that.”
