Iran taught Russia to build Shaheds. Russia industrialised the design and shipped upgraded versions back at 1,000 per day.

Key takeaway

Industrial-scale drone production reshapes the war's attritional arithmetic against depleting defences.

Russia shipped upgraded Geran-2 drone variants to Iran via sea, with delivery completed by end of March . President Zelensky confirmed the transfer. Russia also provided satellite targeting data, according to the Washington Post. Russia builds roughly 1,000 Geran-2s per day. 1

The reversal is strategically remarkable. Iran supplied Russia with the original Shahed-136 drones for use in Ukraine. Russia industrialised the design, upgraded it with jet propulsion and improved guidance, and is now shipping the product back. Iran's single-day intercept numbers on 3 April (47 drones in one UAE engagement alone) may reflect this expanded supply. With THAAD and Arrow stocks depleting, the attritional arithmetic favours the side that can produce munitions at industrial scale.

Deep Analysis

In plain English

Iran originally designed a cheap drone called the Shahed-136 and gave the design to Russia for use in Ukraine. Russia built a factory and upgraded the design, producing 1,000 of them a day. It then shipped upgraded versions back to Iran. This matters because Iran's missiles and drones are being intercepted at high rates, burning through expensive US and Israeli defensive rockets. With Russia supplying cheap drones faster than defences can be rebuilt, the war of attrition favours Iran.

Deep Analysis
Root Causes

Russia's incentive is threefold: degrade US military capacity and attention, test upgraded drone variants in live combat, and deepen Iran's strategic dependency for oil and political cover.

The Geran-2 improvement over the Shahed-136 includes jet propulsion and improved guidance, making it harder to intercept and more accurate. At 1,000 per day, Russia can sustain Iranian strike capacity indefinitely against depleting THAAD and Arrow stocks.

What could happen next?
  • Consequence

    Russian industrial supply allows Iran to sustain drone strike rates indefinitely, accelerating Arrow-3 and THAAD depletion beyond RUSI's March projections.

  • Precedent

    The Shahed-Geran supply loop creates a precedent for reverse-technology transfer between Russia and Iran that will outlast this conflict and reshape both arsenals.

Different Perspectives
Lloyd's of London war-risk underwriters
Lloyd's of London war-risk underwriters
Lloyd's kept its Hormuz war-risk designation unchanged at $10-14 million per voyage even as Brent spiked 7%, holding the split from futures that has run since late May. Underwriters require a Security Council resolution or government certification, not a presidential phone call.
Gulf Cooperation Council states
Gulf Cooperation Council states
Gulf states, having written to the IMO rejecting Iran's Hormuz transit authority, watched a fresh missile exchange land on Kuwaiti soil. Riyadh and Abu Dhabi remain caught between US security guarantees and Iranian fire, with no Gulf state co-belligerent except Kuwait.
China
China
Beijing stayed out of the diplomatic rupture, sending no envoy and offering no public position on the suspended talks. China keeps its bilateral energy corridor with Tehran while declining the exposure of a mediating role Trump barred it from anyway.
Kuwait
Kuwait
Kuwait's air defences engaged two Iranian ballistic missiles aimed at US forces late on 31 May, the second interception in days after invoking Article 51. Repeated strikes test whether Kuwait's politics can sustain hosting US forces as a de facto co-belligerent.
Lebanon and Hezbollah
Lebanon and Hezbollah
Lebanon announced a partial ceasefire under which Hezbollah pledged to stop attacking Israel, the concrete output of Trump's call. Beirut heads to Washington on 3 June with Israeli forces still inside the south, testing whether the truce survives contact.
Israel under Netanyahu
Israel under Netanyahu
Netanyahu stood down the planned Beirut operation under Trump's pressure but kept his ground advance running toward the Zaharani river, the deepest incursion in 25 years, and disputed Trump's claim that troops had turned around. Israel signalled the halt is tactical, not a wind-down.
