The Ministry of Defense rejected speculations about procedure for delivery of S-300 missile defense.
S-300 missile system is designed for defensive objectives to protect industrial bodies, military sites and state organizations against enemies' air strikes.
In 2007, Russia and Iran signed an $800-million deal for the delivery of five S-300 missile defense.
Moscow suspended the deal after the UN Security Council issued an arms embargo on Tehran amid allegations that Iran is planning to produce nuclear arms.
Russian President Vladimir Putin lifted the ban on delivery of S-300 missile defense in April, shortly after the P5+1 and Iran struck the nuclear deal -- Joint Comprehensive Plan of Action.
