Russia stopped Iran’s S-300s for five years. Then it reopened the deal.

The 2007 contract was suspended in 2010 and reinstated in 2015. The reviewed reporting does not document a technology transfer or a specific shipment.

Iran signed a reported $800 million contract for Russian S-300 air-defence systems in 2007. Three years later, Russia stopped the delivery under a ban connected to UN sanctions. A contract remained on paper. The launchers did not move.

The interruption lasted until April 2015, when President Vladimir Putin lifted the ban. Al Jazeera reported that Russia would now supply Iran with a missile-defence system. The reversal made the contract politically available again, but it did not turn an announced supply decision into a documented deployment.

Russia’s own officials added a complication. The original S-300 model was no longer in production, and an S-300VM alternative was under discussion. That is more than a naming detail. A buyer returning to an old agreement may receive a different configuration from the one first negotiated, with fresh questions about price, integration, training and support.

This was a supplier-government decision, not a manufacturing failure. Russia could sign the contract, suspend delivery and lift the restriction years later. Iran had no unilateral way to convert the 2007 agreement into shipments while the Russian ban remained in force.

The saved reporting does not identify a quantity, delivery date, specific shipment or technology-transfer agreement. It does not say whether Iran received the proposed alternative, how the system was supported, or when it entered service. The concrete record is the five-year switch in access: a Russian ban stopped the S-300 route in 2010; a Russian presidential decision reopened it in 2015.
