Russia is technically capable of providing its air defense systems S-300 to Syria within one month, a military-diplomatic source has told TASS, adding that for this the launchers already at the Defense Ministry’s disposal might be used after the required reconfiguration, a military-diplomatic source has told TASS.

According to the official, there are two options of delivering the S-300 to Syria. One is Russia may provide to Syria the export configuration of the air defense launchers. In that case Syria will get them in 18 to 24 months from now. The other possibility is the available systems may be retrieved from the Defense Ministry’s reserves. Those replaced by S-400 in the Russian army might be use, too.

"Naturally, the used S-300 systems that may be taken to Syria will have to be reconfigured to suit the standards of the Syrian air defense. This work may take about a month," the source said.

TASS has no official confirmation of this.

Earlier, the daily Kommersant quoted its own sources as saying that Russia in the near future might start the delivery of S-300 Favorit air defense systems to Syria.
