Tehran is likely to receive Russian S-300 air defence systems in 2015, Iranian Ambassador to Russia Mehdi Sanayee has said.
"I hope Russia will deliver this defence system to Iran in 2015," Iran's FARS News Agency reported Ambassador Sanayee saying during a press conference in Moscow.
In January, Tehran and Moscow signed an agreement to broaden their defensive cooperation and also resolve the problem with the delivery of Russia's S300 missile defence systems to Iran.
Iranian Defence Minister Brigadier General Hossein Dehqan and visiting Russian counterpart General Sergei Shoigu signed the agreement during a meeting in Tehran.
The Iranian and Russian defence ministers agreed to resolve the existing problems which have prevented the delivery of Russia's advanced air defence systems to Iran in recent years.
In 2007, Iran signed a contract worth $800 Million to buy five Russian S300 missile defence systems. The deal was scrapped in 2010 by the then-Russian President Dmitry Medvedev, who was unilaterally expanding on sanctions against Iran imposed by the UN Security Council.
Iran filed a $4 Billion lawsuit against Russia in the international arbitration court in Geneva, which is currently pending review.
Moscow has struggled to have the lawsuit dropped, including by offering the Tor anti-aircraft systems as replacement, media reported in August, adding that the offer was rejected by Tehran.
The S-300 is a series of Russian long range surface-to-air missile systems produced by NPO Almaz, all based on the initial S-300P version. The S-300 system was developed to defend against aircraft and cruise missiles for the Soviet Air Defence Forces. Subsequent variations were developed to intercept ballistic missiles.
The S-300 system was first deployed by the Soviet Union in 1979, designed for the air defence of large industrial and administrative facilities, military bases, and control of airspace against enemy strike aircraft.
