Russia secretly aids Iran in supersonic missile development
Russia has secretly helped Iran develop supersonic cruise missiles since 2023 through a program codenamed C430L, focusing on creating a ramjet engine for high-speed flight. The collaboration involved Russian engineers from Rosoboronexport and NPO Mashinostroyeniya, who analyzed Iranian test data and provided technical advice, though it remains unclear if the missiles have been deployed.
Consensus
- Russia has been involved in a secret program since 2023 to help Iran develop supersonic cruise missiles.
- The program, codenamed C430L, focuses on developing a ramjet engine enabling flight at several times the speed of sound.
- Rosoboronexport and NPO Mashinostroeniya coordinated and executed the project from the Russian side.
- Russian specialists analyzed Iranian test data and provided technical recommendations.
- Iran has built and tested the ramjet engine, but there is no evidence that the completed missile has been deployed or accepted into service.
- The cooperation continued at least through 2026, including after the outbreak of hostilities between Iran and the U.S. and Israel.
- The program required high-level political approval in Russia.
- Experts consider the technology strategically significant and potentially threatening to U.S. naval assets in the region.
