Use of Russian drone technology in Iran

Friday 13 March 2026

The invasion of Ukraine has become the largest laboratory of drone warfare in modern history. No conflict since the Second World War has produced such a dense operational environment for unmanned aerial vehicles, nor such an enormous accumulation of tactical data. Hundreds of thousands of drones have been used in Ukraine for reconnaissance, attack, electronic warfare and air defence suppression. In this environment both Russia and Ukraine have learned extremely rapidly, adapting designs and operational doctrines in months rather than years.

A natural question therefore arises: to what extent might Russia now be transferring the lessons she has learned in Ukraine to Iran, her strategic partner in the Middle East? The answer appears to be that such transfers are not only plausible but already underway, though the relationship between Moscow and Tehran remains complex and reciprocal.

The origins of the drone partnership

The starting point for this relationship lies in Iran’s earlier role as Russia’s supplier. When Russia’s invasion of Ukraine began in February 2022, Moscow possessed limited stocks of inexpensive loitering munitions, the type of drone designed to circle above a battlefield before diving onto a target. Iran however had spent years developing precisely such systems.

The result was a substantial arms arrangement. Iran supplied Russia with the Shahed-136 attack drone and associated technologies, enabling Moscow to deploy large waves of inexpensive one-way attack drones against Ukrainian cities and infrastructure. The agreement included not merely delivery of drones but also the transfer of technical documentation allowing them to be produced inside Russia under the name Geran-2. 

Iranian advisers reportedly assisted Russian forces in Crimea and other occupied territories with training and deployment, embedding Tehran directly into Russia’s war effort. 

From Moscow’s perspective the advantage was obvious. Cheap drones could overwhelm Ukrainian air defences, forcing Kyiv to expend expensive interceptor missiles. This asymmetry has been one of the defining tactical features of the war.

Russia’s transformation of Iranian technology

The relationship did not remain one-sided for long. Once Russian engineers began producing Shahed-derived drones domestically, they began modifying and improving them. Russian factories now manufacture large numbers of these drones each month, having integrated the Iranian design into their own defence industry. 

The battlefield environment of Ukraine has forced continuous innovation. Russian drones have evolved in several respects:

1. Mass deployment: drones launched in coordinated waves to saturate air defences.

2. Navigation and electronic protection: systems designed to resist Ukrainian electronic warfare.

3. Modified propulsion: new variants, including jet-powered versions with longer range and heavier payloads. 

4. Operational integration with missiles and artillery to create combined strike packages.

These improvements are not theoretical. They are the product of daily combat experience against a technologically capable opponent. Russia has launched tens of thousands of such drones during the war, producing an unprecedented data set on drone effectiveness, survivability and counter-measures. 

In effect Ukraine has become a proving ground in which Iranian designs have been subjected to the stress of a modern industrial war.

Evidence of reverse technology transfer

Increasingly there are signs that Moscow is sharing the lessons learned in Ukraine with Tehran. Western intelligence sources report that Russia has begun advising Iran on drone tactics derived from the Ukrainian battlefield. 

This assistance appears to include:

• Guidance on flight profiles, including low-altitude approaches designed to evade radar and air-defence systems.

• Coordinated swarm tactics, where multiple drones attack simultaneously from different directions.

• Targeting methods refined during Russia’s strikes against Ukrainian infrastructure.

British defence officials have suggested that Iran’s recent drone operations show clear signs of Russian tactical influence, particularly in how drones are flown to evade air defences. 

In some cases physical components may also be transferring in the opposite direction. Investigators examining debris from drones used in Middle Eastern attacks have reportedly found Russian electronic protection equipment integrated into Iranian systems. 

The pattern suggests not merely a supplier-customer relationship but an iterative collaboration, in which each country learns from the other’s operational experiences.

Strategic motivations for Russia

Russia’s incentives for sharing such knowledge are not difficult to discern.

First, Iran is one of the few major states willing to provide Moscow with military support in her war against Ukraine. Maintaining that partnership is therefore strategically valuable.

Secondly, Iranian pressure on Western interests in the Middle East serves Russia’s geopolitical purposes. If the United States and her allies must divert military resources to the Persian Gulf or the eastern Mediterranean, fewer resources remain available to assist Ukraine.

Thirdly, the relationship forms part of a broader geopolitical alignment amongst states dissatisfied with Western dominance of international institutions. Russia and Iran have formalised this alignment through a long-term strategic partnership agreement, deepening cooperation in defence and technology. 

From Moscow’s viewpoint, exporting battlefield knowledge from Ukraine may therefore be a relatively inexpensive way of strengthening a strategic ally.

Iran’s strategic gains

For Tehran the benefits are equally substantial. Iran has long invested heavily in asymmetric warfare technologies, particularly missiles and drones. Yet her forces have rarely fought a technologically advanced opponent on the scale seen in Ukraine.

Russia’s war provides precisely that testing ground. By analysing Russian experience against Ukrainian air defences, electronic warfare systems and Western-supplied technologies, Iran gains insight into how her own drones might perform in future conflicts.

This knowledge is particularly valuable in scenarios involving Israel, the United States or Gulf states, all of whom possess sophisticated air-defence networks.

Indeed analysts increasingly argue that the tactics first refined in Ukraine are already appearing in Iranian operations elsewhere. The widespread use of cheap, mass-produced drones in regional conflicts suggests the emergence of a new doctrine of attritional drone warfare. 

Hence Ukraine’s battlefield lessons may be shaping not merely one regional conflict but the future of military doctrine across several theatres.

Limits and tensions in the partnership

Nevertheless the Russia–Iran relationship should not be overstated. There are signs of friction between the two states, particularly regarding intellectual property and the sharing of technological improvements. Some analysts suggest Russia has retained the most advanced modifications of Iranian drones for herself while providing relatively limited technology transfers in return. 

Furthermore Russia’s ability to supply Iran with advanced military systems remains constrained by her own wartime needs. Even if Moscow wished to provide Tehran with large numbers of improved drones or missile technologies, her domestic military requirements might prevent it.

The partnership therefore appears pragmatic rather than ideological. Each side cooperates where interests align but retains its own strategic priorities.

The wider implications

The exchange of drone knowledge between Russia and Iran has implications far beyond either country.

For Ukraine the consequences are immediate. Iranian support enabled Russia to develop her current drone-strike strategy. If Russia now feeds combat experience back to Tehran, the cycle of innovation may accelerate.

For the Middle East the implications are equally significant. States that previously faced relatively simple drone threats may now confront tactics refined against one of Europe’s most sophisticated air-defence environments.

Finally there is the broader lesson that modern warfare increasingly functions as a network of shared experience. Conflicts are no longer isolated laboratories. Instead tactical lessons learned in one theatre rapidly migrate to another.

Where next?

The war in Ukraine has transformed drone warfare from a peripheral capability into a central instrument of modern conflict. In doing so it has generated an immense reservoir of operational knowledge.

Iran originally supplied Russia with the technology that made large-scale drone warfare possible in Ukraine. Yet after years of combat Moscow has adapted and refined that technology, producing new doctrines and improvements derived from the pressures of a major industrial war.

Evidence now suggests that some of those lessons are being transmitted back to Tehran. Tactical advice, technological components and operational insights appear increasingly to flow from the Ukrainian battlefield into the strategic calculations of Iran.

The invasion of Ukraine is not merely a European war. It has become a crucible of military innovation whose consequences are already reshaping conflicts far beyond the front lines of the Donbas. Hence Russian expertise is no longer just a problem for Ukraine; it is a problem for the United States, Israel and the Gulf States in the ongoing conflict in the Middle East.
