A Financial Times report is claiming that Russia has been secretly helping Iran develop advanced supersonic cruise missiles under a programme codenamed ‘C430L’. The multiyear programme began in 2023, claimed the report, which cited leaked Russian communications, travel documents and defence patent analysis. The programme allegedly involves Russian missile specialists, technical exchanges and assistance with a ramjet propulsion system that could allow missiles to travel at several times the speed of sound, the FT investigative report published on Tuesday (Sep 1) said.<h2>How C430L began</h2>According to the report, the defence programme was arranged by Russia’s state arms exporter Rosoboronexport in coordination with NPO Mashinostroyenia, which is a Russian design bureau sanctioned by the US since 2014.Russian arms-export officials and senior NPO Mashinostroyenia engineers repeatedly travelled to Iran before a formal agreement was signed with Iran’s Ministry of Defence and Armed Forces Logistics in November 2023, said the report.Senior NPO engineers with expertise in cruise missiles and air-breathing propulsion, including a specialist in supersonic ramjet technology were involved, it claimed.<h2>Supersonic missile for Iran? The ramjet technology&nbsp;</h2>Ramjet engines use a technology specifically designed for supersonic speeds. A ramjet propulsion system is at the centre of the C430L programme. Unlike conventional rocket propulsion, a ramjet uses the missile’s forward speed to compress incoming air before combustion, allowing sustained high-speed flight within the atmosphere.Military experts told FT this tech was almost certainly for anti-ship and land-attack cruise missiles. If developed, these weapons could threaten US aircraft carriers, warships and other military assets in the Middle East.Ramjet tech is covted for long by Iran, which built and flight-tested it.

Inside C430L: The alleged secret Russian mission to help Iran with supersonic missiles

Iranian Foreign Minister Abbas Araghchi on Monday (Apr 27) blamed the United States for the failure of peace talks in Pakistan. He made the remarks after arriving in Saint Petersburg for the scheduled talks with Russian President Vladimir Putin. Araghchi also stressed that safe passage through the Strait of Hormuz is an important issue as tensions continue to flare in West Asia, with the US and Iran ramping up their blockade in the world’s most strategic waterway.“The US approaches caused the previous round of negotiations, despite progress, to fail to reach its goals because of the excessive demands,” Araghchi was quoted as saying by Iranian state media.He added that “safe passage through the Strait of Hormuz is an important global issue.”While an Iranian delegation arrived in Pakistan earlier to hold high-level Pakistani officials as part of their efforts in ongoing mediation of the war, Foreign Ministry Spokesperson Esmaeil Baqaei said that no meeting was planned to take place between Iran and the US.Meanwhile, US President Donald Trump on Saturday said that he had cancelled Steve Witkoff and Jared Kushner’s trip to Pakistan for the peace talks after being unimpressed with Iran’s position. The tensions in West Asia continue to rise amid a fragile ceasefire, with uncertainty looming over peace negotiations.<h2>Araghchi to meet Putin</h2>The Iranian foreign minister is set to hold talks with Putin. After arriving in Russia, he noted that Tehran and Moscow have always held consultations on various issues.“As you see, we have always held close consultations with Russia on a wide range of issues, particularly regional ones, and also held constant bilateral talks,” he said in a video posted on his Telegram channel.Speaking about talks in Pakistan, Araghchi said, “We held good consultations with our friends in Pakistan… The trip was successful. We assessed the outcome of our recent [meetings] and discussed in what direction and under what conditions talks can move on.”He also mentioned the talks held in Oman, saying that “Oman is a friendly country that is close to us; it has taken a very good stance in the war… We and Oman are the two coastal states of the Strait of Hormuz so we needed to hold consultations on the matter. The safe passage of ships through the strait is an important global issue and as the two countries that control the strait, we and Oman need to maintain close coordination to ensure our mutual interests.”Disclaimer: WION takes utmost care to accurately and responsibly report ongoing conflicts in West Asia involving Israel, Iran, the US, Gulf nations and non-state actors like Hezbollah, Hamas, Houthis, Islamic State, and others.
