Key takeaway

Iran's drone campaign proved the cost-exchange crisis is operational, not theoretical.

CSIS published its first detailed analysis of Iran's drone campaign in the Gulf on 3 April 2026. Since Operation Epic Fury began on 28 February, Iran has launched 4,446 drones and 1,725 missiles. 71% of recorded strikes were drone-based. ¹

The UAE absorbed 55% of all incoming strikes. The initial wave on 1 March comprised 1,206 strikes; sustained pressure continued at 190 to 392 per day. CSIS framed the campaign as a deliberate cost-imposition strategy: a Shahed-136 costs between $20,000 and $50,000, while defending against it with a Patriot missile costs 80 to 200 times more. ²

The report recommended adopting Ukraine's approach (cheap interceptor drones at $2,000 to $4,000 per unit) rather than missile-based defence . CSIS also noted evidence of possible Russian Geran-2 variants in Iranian stocks, suggesting reciprocal Iran-Russia technology transfer. ³ The data gives the Pentagon's Drone Dominance programme its most concrete demand signal yet: the threat is not hypothetical, and the current arsenal is orders of magnitude too small.

Deep Analysis

In plain English

Iran has been firing hundreds of low-cost drones at US allies in the Gulf every day for five weeks. Each drone costs roughly the same as a family car. To shoot them down, the US has been using missiles that cost more than a luxury house. CSIS, a Washington think tank, counted the numbers: 4,446 Iranian drones launched, the UAE taking 55 per cent of the hits. The report confirmed what many had feared: Iran is winning the economics of this conflict even if it is not winning tactically. The suggested fix is to stop using expensive missiles and start using cheap counter-drones instead, costing $2,000 to $4,000 each, similar to what Ukraine has been doing.

Deep Analysis

Root Causes

Iran developed its Shahed programme specifically in response to US precision-strike dominance, mirroring the logic of anti-ship missiles used to threaten carrier groups: impose unacceptable costs on a superior adversary rather than match them platform-for-platform.

The UAE's 55% share of incoming strikes reflects its role as the primary forward base for US forces in the Gulf, making it the highest-value target set for cost-imposition.

Evidence of Russian Geran-2 variants in Iranian stocks suggests the Iran-Russia technology transfer relationship is reciprocal: Russia received Shahed-136 designs for use in Ukraine; Iran received upgraded variants in return, deepening the campaign's industrial underpinning.

What could happen next?

CSIS data provides the Pentagon's Drone Dominance programme with a concrete demand signal, likely accelerating Gauntlet II timelines and funding.
Evidence of Russian Geran-2 variants in Iranian stocks will intensify pressure on Gulf states to accept tighter sanctions enforcement on Iran-Russia technology transfer.

Source Landscape

This story draws on mixed-leaning sources from United States

United States

Primary parallel: Germany's V-1 flying bomb campaign against Britain in 1944-45 established the first modern precedent for mass-produced expendable weapons overwhelming fixed defences: the UK spent approximately £350 on each interception while Germany spent £125 per V-1 produced, a 2.8:1 ratio that forced the development of proximity-fuze anti-aircraft shells.

Counter-parallel: The Gulf War (1991) showed that concentrated air defence, including Patriot batteries, could achieve high intercept rates against ballistic missiles at acceptable cost when stocks were pre-positioned; the Iran campaign differs because stocks were not adequate for a five-week high-intensity campaign.

At $20,000 to $50,000 per Shahed-136 and a $4 million Patriot intercept, Iran is generating a cost ratio of 80:1 to 200:1 against US missile defences. The 4,446 drones launched represent between $89 million and $222 million in Iranian expenditure. The intercept bill on the US-allied side, if primarily missile-based, would range from $7 billion to $18 billion depending on mix.

CSIS's recommendation to adopt Ukraine-style cheap interceptors at $2,000 to $4,000 each would reduce the ratio to 5:1 to 25:1, still unfavourable but sustainable rather than catastrophic.

Consensus view: CSIS analysts Seth Jones and Tom Karako characterised the 71% drone fraction as confirmation that Iran deliberately designed the campaign to impose maximum cost on missile-based defences, following lessons from Houthi operations in 2023-25 that proved the strategy effective at a smaller scale.

Counter-view: Iranian state media framed the campaign's scale as evidence of strategic self-sufficiency: Iran has the industrial capacity to sustain a 190-to-392-drone daily sortie rate against peer-level defences without foreign resupply, a capability the US has not yet demonstrated in reverse.

Key tension: Whether the Russian Geran-2 variant evidence indicates genuine Iran-Russia technology co-production or simply Iranian reverse-engineering, which has different implications for sanctions enforcement and supply chain interdiction.

Different Perspectives

Anduril

Anduril views consolidated procurement as enabling rapid scaling — the $20 billion enterprise contract replaces 120 separate Army contracts with a single vehicle. Arsenal-1's early opening positions it to argue manufacturing readiness that CCA competitors cannot yet demonstrate.

Ukrainian drone manufacturers

Ukrainian firms have battle-tested interceptors priced at $2,100–$2,500 per unit and demand from 11 nations, but the wartime export ban forces partnerships with Western firms rather than direct sales.

IISS

IISS characterises drone innovation in the Russo-Ukrainian war as adaptation within existing military paradigms rather than a transformation of warfare — a more cautious assessment than the Pentagon's procurement urgency suggests.

US Pentagon, Anduril and Shield AI

The Pentagon awarded Anduril a $20 billion enterprise vehicle and confirmed Gauntlet II's live EW red team, prioritising procurement speed over competition; Anduril began YFQ-44A production four months early. Shield AI countered by raising $2 billion and validating Hivemind on a European airframe, betting multi-platform interoperability hedges against Anduril's platform lock.

Volodymyr Zelenskyy / Ukraine

Zelenskyy publicly disclosed that 10 shadow drone factories have been built abroad to circumvent Ukraine's wartime export ban, signed 10-year defence deals with Saudi Arabia and Qatar, and deployed 228 specialists across five Gulf states. The disclosure is a calculated signal that the ban is fracturing and Kyiv is seeking revenue structures independent of Western aid.

Saudi Arabia

Saudi Arabia signed a 10-year defence deal with Ukraine and accepted the deployment of Ukrainian counter-drone specialists the US declined to partner on in August 2025. The Gulf pivot reflects Riyadh's assessment that Ukrainian combat-proven doctrine at $2,500 per interceptor is more cost-effective than Patriot-dependent air defence.
