[Ed. – It isn’t clear what the Iranians still lack to have a fully functional battery. They may lack nothing — to have at least one. They’re still awaiting deliveries later this year, but that doesn’t mean they are unable to field a complete system now. If the Iranians are willing to have it known that they’ve received the missiles, they’re not trying to hide from potential preemptive attack at this point. The S-300 is a relatively simple mobile system, reportedly easy for operators to learn. It won’t require a lengthy ramp-up to get to “initial operational capability” (IOC). In the worst case — if not the most likely — the first battery up could be as early as September.]
Russia has delivered the missile part of S-300 surface-to-air defense system to Iran, Tasnim news agency reported on Monday, moving to finish the delivery of all divisions of the system to Tehran by the end of this year.
“The first shipment of missiles of S-300 missile system has recently entered Iran that shows Iran’s determination to equip its air defense circle with this system,” Tasnim news agency, which is close to the Revolutionary Guards, reported.
Russia’s agreement to provide Iran with S-300 has sparked concern in Israel, whose government Iran has said it aims to destroy.
