Russian presidential aide on military-technical cooperation Vladimir Kozhin said that Iran will receive advanced anti-aircraft missile systems S-300. Reported RIA Novosti .
According Kozhin since the conclusion of the contract between the two countries in 2007 the complex is obsolete so it was decided to modify specifically for Iranian customers.
In May 2015 reported that Iran will receive from the Russian missile and anti-aircraft complexes directly from the factory. It was also noted that the prices will be modified to reflect changes in exchange rates.
