Russia Helps Iran Develop Supersonic Missiles

Russia has allegedly been secretly helping Iran develop advanced supersonic cruise missiles under a multi-year covert programme. The programme, codenamed C430L, began in 2023 and involves some of Russia's most experienced missile specialists. The aim is to help Iran develop a ramjet propulsion system that could enable cruise missiles to travel at several times the speed of sound.

According to an investigation by the Financial Times, the programme continued during the US-Israeli conflict against Iran. The investigation was based on leaked Russian correspondence, travel records, and analysis of military patents. Experts believe that the programme would require political clearance from the very top in Russia.

The ramjet technology could be used in anti-ship and land-attack cruise missiles. Supersonic cruise missiles combine high speed with the ability to fly at low altitude, reducing the time available for air and missile defence systems to detect and intercept them. This technology could be particularly significant for Iran in the Gulf, where US and allied forces operate advanced land- and sea-based defensive systems.

Iran has already built and flight-tested the ramjet propulsion system, although there is no evidence that a Russian-assisted supersonic cruise missile has been deployed. The leaked correspondence reviewed by the Financial Times indicates that discussions over the programme continued into this summer.

The reported cooperation comes amid increasingly close strategic and military ties between Russia and Iran. Tehran has supplied Russia with Shahed attack drones, which have been used in the conflict in Ukraine. The development of supersonic cruise missiles would give Iran a qualitatively new strategic weapon system that could threaten US Navy vessels.

Experts believe that the transfer of this technology from Russia to Iran is one of the most significant known transfers of strategic military technology from Moscow to Tehran. The development of supersonic cruise missiles would be a significant escalation in the region, particularly given the already heightened tensions between the US and Iran.

The US has been conducting strikes against Iran, and the development of supersonic cruise missiles would give Iran a new capability to counter US naval power in the region. The situation is being closely watched by experts, who believe that the development of these missiles could have significant implications for the balance of power in the region.

In conclusion, the reported cooperation between Russia and Iran on the development of supersonic cruise missiles is a significant development that could have major implications for the region. The development of these missiles would give Iran a new capability to counter US naval power, and could lead to a significant escalation in the conflict between the US and Iran.
