Iran has reportedly received missile part of S-300 surface-to-air defense system from Russia, moving to finish the delivery of all divisions of the system by yearend.
"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, Tasnim news reported Monday.
Iran displayed part of the Russian-made S-300 air defense missile system that included 2 radar systems of S-300, its carrier and command vehicles as well as the crane for lifting its missiles in a military parade held in Tehran to mark its National Army Day in April this year.
A contract for the supply of five battalions of S-300 systems was signed by both the countries in 2007. The $800 million contract was cancelled in 2010 by the then Russian President Dmitry Medvedev and money returned following UN sanctions imposed on Iran.
In January 2015, Russian Defense Minister Sergei Shoigu and his Iranian counterpart, Defense Minister Hossein Dehghan, agreed to move forward with the sale of five S-300PMU-1/SA-20 Gargoyle SAM systems (40 launchers) for $800 million.
