Iran & HESA: Shahed-136 Technology Transfer to Russia

Origins: Iran, HESA and the Shahed-136

The Shahed-136 is a delta-wing loitering munition built around a small piston engine, a satellite-and-inertial guidance package and a warhead in the region of 40–50 kg. It is cheap, slow and unsophisticated by the standards of cruise missiles, but it can be launched in large salvos to saturate and exhaust an opponent's air defenses. Iran developed the airframe, and the state-linked Iran Aircraft Manufacturing Industrial Company — HESA — is widely identified as its manufacturer.

Russia began using the type against Ukraine in the autumn of 2022, initially relying on Iranian-supplied airframes. The early drones were imported as finished or near-finished units. What turned a niche export into a strategic weapon was the decision to move production inside Russia, removing the logistical bottleneck of cross-border deliveries and the political exposure of relying on a single foreign supplier.

From Exports to Technology Transfer

The relationship evolved in stages: finished-drone sales, then knock-down kits for local assembly, then full localization. Leaked internal Alabuga documents reported by researchers and journalists indicate Iran provided Russia with design data, including guidance on producing the printed circuit boards used in the drone, plus a list of the production equipment and machinery required to build the airframe domestically. Reporting suggests the localization effort targeted roughly 90% domestic content over time.

This is a textbook case of military technology transfer rather than a simple arms sale. By 2025, reporting indicated that Russia had become substantially self-sufficient in airframe and engine production — to the point that some accounts described Moscow sidelining Tehran in parts of the supply chain. The Institute for Science and International Security documented new construction and engine-production buildings at the site, consistent with deepening localization.

Iran's gain was strategic and financial; Russia's was a sovereign, scalable production line for a weapon it could fire daily. The transfer also illustrates how sanctioned states pool capabilities: design from one, manufacturing scale from another, and dual-use microelectronics sourced through third countries.

The Alabuga Plant in Tatarstan

Alabuga is a Special Economic Zone in Yelabuga, in the Russian republic of Tatarstan, originally established to attract civilian industry. Satellite imagery analysis and leaked documents show parts of it were converted into the principal Russian assembly — and increasingly manufacturing — site for the Geran-2 / Shahed-136. Analysts at ISIS-online and CSIS Beyond Parallel have tracked the expansion of production halls, dormitories and, critically, a building commissioned to produce the drone's gas-piston engine.

The plant became notorious for more than drones: reporting documented the recruitment of a young and at times coerced workforce, including foreign labour, to staff the assembly lines. That human dimension underlines how seriously Russia treated scaling output. For Ukraine, Alabuga is a strategic target set; for analysts, it is the single most important node in the Shahed supply chain to monitor.

Production Ramp Estimates

Output figures are opaque and contested, and should be read as intelligence ranges rather than audited numbers. The original Alabuga contract reportedly aimed to produce 6,000 units by around September 2025 — a target that Ukrainian military intelligence and open-source analysts said was reached well ahead of schedule. By late 2025, Ukrainian and Western assessments pointed to monthly Shahed-class output running into the thousands, a step change from the dozens per month seen early in the campaign.

⚠ Figures are approximate and come from intelligence services and OSINT analysis (IISS, ISIS-online). They are uncertain and shift over time. Not investment advice.

Western Components & Data Limits

Despite localization, the Shahed-136 still depends on imported microelectronics. Investigations co-authored by IPHR, NAKO, Truth Hounds and Global Diligence, alongside teardown work by Conflict Armament Research, have repeatedly recovered Western-made parts inside downed airframes: microprocessors, semiconductors, memory chips and other dual-use electronics. Researchers have identified components from more than a dozen firms based in the United States, Japan, Canada and Switzerland, with a large share originating in the US.

This matters for two reasons. First, it shows that sanctions enforcement against dual-use chips can raise the cost and complexity of production even where it cannot stop it. Second, it cautions against treating Russia's drone industry as fully self-contained: the airframe may be Russian-built, but the brains often are not.

All figures here carry real limitations. Production estimates derive from intelligence assessments and satellite analysis, not company disclosures; component findings reflect specific recovered samples, not every drone. Read every number with its source and as-of date, and treat single precise figures with caution.
