Report: Russia Helping Iran to Develop a Supersonic Anti-Ship Missile

Russia is assisting Iran in developing a supersonic anti-ship cruise missile, according to a Financial Times report. The cooperation, under Project C430L, has involved Russian comments on Iranian flight test telemetry, with the bulk of research and development taking place in Iran. The report notes that no developmental milestone has been achieved and operational deployment is not imminent.

Why it matters: This development bears on the theme of maritime security and the balance of naval power in the Gulf of Oman, where US Navy ships are enforcing a blockade against Iran.
