Iran deploys S-300 air defense missile systems in the Islamic Republic

The Iranian army began urgently deploying S-300 air defense systems recently received from Russia across the Caspian Sea. According to the Russian press agency TASS, In 2015, Iran has signed a contract with Russia for the delivery of S-300PMU2 air defense missile systems. Russia’s Federal Service for Military and Technical Cooperation said in October 2016 that Russia had completed the delivery of S-300 systems to Iran.

One may assume this deployment is the result of a fire and explosion that recently occurred at one of the secret Iranian plants involved in the military sector, possibly linked to nuclear activity. Several experts then expressed the opinion that this could well be the result of an attack by Israeli aircraft, which is denied by the Iranian government and, of course, not commented by the Israeli one.

Currently, S-300 systems are the most long-range and modern weapons in the arsenal of Iranian air defense. The S-300 (NATO reporting name: SA-10 Grumble) is a series of initially Soviet and later Russian long range surface-to-air missile systems produced by NPO Almaz, based on the initial S-300P version. The S-300 system was developed to defend against aircraft and cruise missiles for the Soviet Air Defense Forces. Subsequent variations were developed to intercept ballistic missiles.

The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defense of large industrial and administrative facilities, military bases and control of airspace against enemy strike aircraft. The system is fully automated, though manual observation and operation are also possible. Components may be near the central command post, or as distant as 40 km. Each radar provides target designation for the central command post. The command post compares the data received from the targeting radars up to 80 km apart, filtering false targets, a difficult task at such great distances.[citation needed] The central command post features both active and passive target detection modes.

The project-managing 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 named "OKB-2" and "OKB-8").
