The contract for selling S-300 to Iran was concluded back in 2007 and resumed in 2015
MOSCOW, October 13. /TASS/. Russia has supplied the last air defense systems S-300 to Iran it was obliged to provide under a bilateral contract, the Federal Service for Military-Technical Cooperation said
“Yes, it is through with the supplies,” the FSMTC official said in reply to a question.
Iranian Defense Minster Hossein Dehghan late last August said Tehran hoped the supplies would be completed within a month.
The contract for selling S-300 to Iran was concluded back in 2007 only to be suspended in 2010. In the spring of 2015 Russian President Vladimir Putin lifted the ban from the sale of S-300 to Iran. The contract took effect in November 2015.
