The Iranian military has acknowledged that its new air defense missile systems are operational.

Iran has successfully tested its Russian-supplied S-300 air defense system this month.

Air defenses around the Fordow uranium enrichment facility have purportedly been reinforced by Russian SAMs.

The first batch of missiles for the S-300 air defense system has recently been delivered, Iran claims.

The Kremlin expects the rest of the air defense systems to be supplied by the end of 2016.

Sources in Moscow and Tehran confirmed that the first batch of S-300 missile systems arrived in Iran.

A Russian diplomat expects the first S-300 delivery to take place in the coming days.

Russia has announced it will supply the missile system to Iran, but Moscow may have another objective in mind.

The controversial weapon systems could already be delivered by the end of this year.
