Iran announced that S-300 air defense systems were to be deployed countrywide
Iran started to use S-300 air defense systems along the Caspian Sea immediately after purchasing from Russia. According to TASS, a Russian news agency, Iran entered into agreement on the procurement of S-300PMU2 air defense systems with Russia in 2015.
The Russia Federal Service for Military-Technical Cooperation said that Russia completed the delivery of S-300 systems to Iran in October 2016.
This deployment may have resulted from the fires and blasts that took place in one of the secret Iranian facilities operable in the military sector, possibly related to nuclear activity. Some sources state that these explosions and fires in Iran were ignited by Israel.
Currently, S-300 systems are known to be the systems with the longest rage and most modern air defense system in Iran’s inventory. S-300 (NATO Code: SA-10 Grumble) is a series of Soviet and later Russian long-range surface-to-air missile systems produced by NPO Almaz based on the first S-300P version.
The S-300 system was first deployed by the Soviet Union and was designed for air defense of large industrial and administrative facilities, military bases and control of airspace against enemy attack aircraft. It also allows manual surveillance and operation, but is fully automated. The components can be stationed near the central command post or up to 40 km away. Each radar provides target identification for the central command post. The command center is able to filter and compare the data received from targeting radars up to 80 km. The command center also has both active and passive target detection modes.
The developer of the S-300 is Almaz-Antey. S-300 uses missiles developed by both MKB “Fakel” and NPO Novator design bureaus (separate government corporations previously called “OKB-2” and “OKB-8”).
