Multiple outlets report that Russia is helping Iran develop supersonic cruise missiles through a programme reportedly known by the codename C430L. The accounts say the arrangement involves the transfer of sensitive military technology that Iran has sought for years, with the missiles intended to be capable of high-speed strike missions.

One report says the project focuses on the transfer of “highly strategically sensitive” technology and frames it as part of a broader effort to accelerate Iranian missile capabilities. Another source describes the initiative as being arranged by Russia’s state arms exporter, Rosoboronexport, in coordination with NPO Mashinostroyenia, an entity under US sanctions. The reports also say the programme begins in 2023, but they do not provide further publicly verifiable technical details or confirm deployment plans.

Across the coverage, the main points are consistent about a Russian-Iranian missile technology cooperation labelled C430L, its claimed start in 2023, and the involvement of Russian state-linked arms channels. However, the sources differ in emphasis, with some focusing on the purported strategic sensitivity and end-use implications, while others highlight the named organizations and procurement pathway.
