Russian Defense Minister Sergei Shoigu on Monday said that Syria's air defense forces would be armed with S-300 air defense systems and that Russia's radio-electronic warfare units will jam satellite navigation, onboard radars and communication systems of combat aircraft attacking targets in Syria.
The Kremlin also accused Israeli pilots of "premeditated actions", warning the incident would harm relations between the two countries.
"A modern S-300 air defense missile system will be transferred to the Syrian armed forces within two weeks", he added.
Israel's military said in a statement its jets "did not hide behind any aircraft and that the Israeli aircraft were in Israeli airspace at the time of the downing of the Russian plane". Russia blamed Israel for the incident, which led to the deaths of more than a dozen Russian airmen.
The Kremlin insisted that the weapons delivery was not directed at any third country. Moscow blamed the friendly fire incident on Israeli pilots using the larger Russian plane as "cover".
However, defense analysts have questioned whether an S-300 system in Syrian, not Russian, hands could threaten Israel's air power in the region and prevent it from being able to conduct strikes against targets in Syria.
Earlier Monday, Moscow announced new security measures to protect its military in Syria, including supplying the Syrian army with an S-300 air defense system and jamming radars of nearby warplanes.
The missile system, originally developed by the Soviet military but since modernised, fires missiles from trucks and is created to shoot down military aircraft and short- and medium-range ballistic missiles.
"Supplying S-300 increases risk by unprofessional Syrian operators first and foremost to the Russian air force, to Israel, the United States and the coalition as well as to civil aviation", Yadlin said. But the Russian military came out on Sunday, renewing the accusations against Israel. Earlier in the war, Russian Federation suspended a supply of S-300, which Israel feared Syria could use against it.
Russian Federation has given Assad crucial support throughout the war in Syria, which began with a government crackdown on protesters in March 2011.
Bolton told reporters in New York: "There shouldn't be any misunderstanding here ..."
Israel's former Military Intelligence chief Amos Yadlin, who now heads the influential Institute for National Security Studies in Tel Aviv, said he assumed the air force would work quickly to destroy the S-300, if it were indeed handed over to Syria. "We're not going to leave as long as Iranian troops are outside Iranian borders, and that includes Iranian proxies and militias".
