MOSCOW (Sputnik) — He said the systems "reliable ensure the safety of our servicemen" in Syria.
"Regardless of today's US attack on the Syrian air force air base, our air base [in Hmeymim] and logistics center in Tartus are secured from the sea and from the air by S-300 and S-400 systems," Ozerov said.
Earlier in the day, the Russian Defense Ministry announced its plans to bolster and increase the effectiveness of the air defense system in Syria after the United States carried out attacks against a Syrian armed forces airfield.
On Thursday night, the United States launched 59 Tomahawk cruise missiles at the Syrian military airfield in Ash Sha’irat, located about 40 kilometers (25 miles) from the city of Homs. US President Donald Trump said the attack was a response to the alleged chemical weapon use in Syria's Idlib on T uesday, which Washington blames on the Syrian government.
The S-400 system was deployed at the Hmeymim following the Turkish Air Force's November 2015 downing of a Russian Su-24 bomber on the Syrian-Turkish border.
In October 2016, the Russian Defense Ministry said that a S-300 system was sent to Syria to ensure the safety of the Russian naval base in Tartus. According to media reports, the system deployed in Syria is S-300V4 — NATO designation SA-23 Gladiator — that is capable of striking tactical and strategic aircraft, medium-range ballistic missiles, tactical missiles as well as cruise missiles.
