Iran signed a secret missile agreement worth approximately €500 million (approximately $589 million) with Russia in order to rebuild its air defense system, the Financial Times claimed in a report published on Sunday, Anadolu reports.

An agreement was signed between Iran and Russia in Moscow in Dec. 2025, according to information obtained by the newspaper.

Under the agreement, Russia is expected to deliver 500 Verba portable launch units and 2,500 9M336-type missiles to Iran within three years.

As part of the roughly €500 million deal, the missiles are planned to be delivered to Iran in three separate phases between 2027 and 2029.

Some sources indicated that certain systems may have been delivered to Iran earlier than the scheduled timeline, according to the daily.
