“All divisions have been supplied,” Fomin said as cited by Russia’s RIA Novosti news agency on Thursday.
On April 17, Iran displayed part of the sophisticated missile system in a military parade in Tehran, held to mark the National Army Day.
Later in July, Iran received the first batch of missiles of the Russian-made air defense system.
The gear unveiled in the ceremony included 2 radar systems of S-300, its carrier and command vehicles as well as the crane for lifting its missiles.
Under an initial contract signed in 2007, Russia was required to provide Iran with at least five S-300 defense system batteries. But the contract, worth more than $800 million, was revoked after then-President Dmitry Medvedev banned the supply of those systems to Tehran in 2010.
Later, Iran lodged a $4 billion lawsuit at an international court in Geneva against Russia’s arms export agency. However, Russian President Vladimir Putin decided in April last year to lift the ban on the S-300 missile system delivery to Iran.
Back in July, Iran’s Air Defense Commander Brigadier General Farzad Esmaili said S-300 would be fully brought into operation until the end of the current Iranian year (March 20, 2017).
