There are Russian reports quoting Iranian Brigadier General Ahmad Reza Purdastan as revealing that Iran and Russia are working a deal involving the T-90 tank. The deal could include production of the T-90 in Iran (the T-90 is no longer Russia’s most advanced tank).
Iran is still awaiting delivery of now outdated Russian S-300 anti-aircraft system, which was put on hold by UN sanctions. In April this year Russian President Vladimir Putin ordered the delivery of the S-300 system to begin. As of today no deliveries have actually transpired.
So far there’s no mention by Iranian news media of any deal to buy T-90s.
