- 06Russia may hesitate to supply the advanced systems to Iran due to its own ongoing military commitments in Ukraine.
- 07No official agreement has been confirmed between the two nations, though Iranian officials express optimism about securing the deal.
To advance the deal, Iranian Supreme Leader Mojtaba Khamenei dispatched Mohsen Rezaei, the secretary of Iran's Supreme National Security Council, to the Kremlin on Thursday, November 5, 2026. Rezaei delivered a personal letter from Khamenei to Putin, with the primary request being the supply of the S-400 systems. The S-400 is capable of detecting and intercepting aerial threats, including aircraft, drones, and missiles, over hundreds of kilometers.
Tehran's renewed push for these systems follows previous American and Israeli strikes that reportedly destroyed Iran's existing air defense infrastructure, including radars and anti-aircraft batteries. While Iran has previously received older S-300 systems from Russia, there is no official confirmation of an agreement for the S-400s, and Russia may hesitate to supply them due to its own military commitments in Ukraine.
