russia responds to it's downed planes

Military Times | New Russian surface-to-air missiles in Syria, DoD confirms

U.S. pilots flying over Syria and Turkey will be in range of advanced Russian-made surface-to-air defense systems, Pentagon officials said.

U.S. intelligence shows that Russia is following through on plans to send S-400 missile systems into its military base in Syria, the officials said.

With a reported range of up to 248 miles, those missiles could put at risk most U.S. combat aircraft flying over Syria.

Russian President Vladimir Putin ordered the S-400 missiles to Syria one day after a Turkish F-16 aircraft shot down a Russian Su-24 jet last Tuesday. Turkish officials said the Russian aircraft veered into Turkish airspace for less than 30 seconds and was fired upon only after repeated verbal warnings.
