According to Iranian sources, the second batch of S-300 surface-to-air missile systems will be delivered in the near future.
Under a contract signed back in February between Iran and Russia, the missile systems will be delivered to Iran in two parts. Iran took delivery of the first consignment in mid-April.
Two radar systems together with its carrier and command vehicle, as well as a crane belonging to the S-300 system were seen in a military parade in Tehran on April 17.
Iran had purchased the S-300 from Russia in 2007.
