On October 19, a Russian military-diplomatic source told the TASS news agency that Russian specialists are converting S-300PM air defense systems, which had been delivered to Syria, into the S-300PMU-2 Favorit version.
“In October, three battalions of S-300PM systems and their ammunition load were delivered to Syria. Later, a regimental command post was brought to the country. All the hardware makes part of the S-300PM equipment set, except for the reconnaissance and air target detection radar of the regiment’s command post, which is part of the S-300PM-2,” the source told TASS.
According to the source, the specialists will change codes and letter frequencies of the ground interrogator and the letter frequencies of the radar for Syrian versions. The specialists work will reportedly end before November.
The S-300PM version uses domestic Russian codes and letter frequencies, which can’t be shared with any other country. However, the S-300PMU-2 Favorit is the export version, which will allow Syria to use its own codes and letter frequencies and integrate the systems into its air defense network.
Russia decided to supply Syria with the S-300 systems following the downing of the Il-20 intelligence plane last month. The step will enhance the capabilities of the Syrian Arab Air Defense Forces (SyAADF) and improve the security of Russian troops deployed in Syria.
