Iranian-supplied drones are being used by Moscow to terrorise Ukrainian civilians and to strike at the country’s electricity generating and distribution system

For years the headlines have covered the controversies over advanced Russian air defence systems heading to Iran. But now the arms traffic is very much in the other direction, writes Jonathan Marcus of the Strategy and Security Institute, University of Exeter.

Russia’s predicament in Ukraine has prompted Moscow to turn to Tehran for stocks of precision-guided weapons. Its own arsenals are fast running out.

There have been a number of instances where coastal defence and air defence missiles have been used by the Russians to strike at land targets in Ukraine – a role for which they are not best suited.

Transport flights have been monitored heading from Iran to Russia. Reports from US sources suggest that Iranian trainers from the IRGC – the Iranian Revolutionary Guard Corps – have deployed to a base in Crimea to teach Russian personnel how to operate the systems.

Wreckage from drones that have been shot down – both Iranian Shahed-131 loitering munitions (colloquially known as kamikaze drones) and the larger Shahed-136 – has been analysed. There is no doubt that Tehran, despite its denials, is compensating for a significant shortfall in Russia’s arsenal.

What is Russia's 'kamikaze' drone?

This is clearly not good news for Ukraine. While a significant number of the Iranian-supplied drones have been shot down there could be worse to come.

Iran has more capable loitering munitions in its arsenal. And there are fears that even more dangerous Iranian weapons – ballistic missiles – could soon be on their way to Russia.

These carry much larger warheads than the drones and Ukraine’s anti-ballistic missile capability is limited. This could add a new level of complexity to Western efforts to bolster Ukraine’s anti-air and anti-missile defences.
New tensions

But what of the wider ramifications of this deepening relationship between Moscow and Tehran?

There could be implications for the future of the moribund nuclear agreement between the international community and Tehran. Furthermore the delicate balance of forces in Syria could be altered with significant consequences for Israel and, in turn, for its relationship with Moscow.

Clearly both Russia and Iran need friends. They are both isolated and embattled.

Russia is facing economic sanctions due to its aggression against Ukraine, a war which is not going well for Moscow. Iran’s regime is also under sanction for its nuclear programme and human rights record, and it is facing massive discontent at home.

They are both part of a small “club” of authoritarian nations, along with China, that seek not just to pursue their own regional strategic goals but also, more broadly, to strike back against what they see as a US-dominated global order.

Iran’s security clamp-down at home has already drawn additional economic sanctions from the West. Now its weapons transfers to Russia are being seen by the United Kingdom and France as a breach of UN Security Council resolution 2231 that was passed in the wake of the 2015 nuclear deal.

This could potentially lead to some nuclear-related sanctions being restored. These new tensions will further undermine efforts to return to the JCPOA, the international deal designed to constrain Iran’s nuclear activities which was abandoned by the Trump Administration in May 2018.

Efforts to restore the deal have lapsed at least until after the US Mid-Term elections on 8 November. Meanwhile Iran has continued to make progress in its enrichment activities.

The Iran nuclear dossier is a looming shadow for the West as its focus is firmly fixed upon Ukraine. Russia – one of the key parties to the original deal – is hardly going to pressure its new arms supplier to give ground.
Syria factor

Nonetheless, the relationship between Moscow and Tehran is driven by circumstance rather than any deep ideological bond.

Russia’s relationship with Iran has long had a measure of ambivalence; a good example is their differing ambitions in Syria.

Russia’s military intervention saved the Assad regime. Iranian manpower, weaponry and militias were also crucial to his survival.

But Russia, which still maintains a presence in Syria, has never been enthusiastic about Tehran’s regional ambitions there. However it has not acted to contain Iranian influence in quite the way Israel would have wished. That said, it has done little to thwart Israeli air strikes aimed at reversing Iran’s build-up in Syria.

Israel’s tricky balancing act over Ukraine

Could the new dynamic in Russia-Iranian relations change this? While some Russian air defences and troops have been removed from Syria Moscow still has the capacity to interfere with Israeli operations.

This has been one of the guiding concerns influencing Israel’s tentative support for Ukraine.

But what of the future? Suppose for example that Russia decided to transfer even more advanced weaponry to Iran in return for its assistance, what then? Might this prompt a shift in Israel’s attitude to Kyiv?

That for now, with an Israeli general election looming, seems unlikely. But the new Russia-Iran relationship has the potential to impact global affairs way beyond the war in Ukraine.
