The Shahed-136 is an Iranian-designed, one-way attack loitering munition that has become central to Russia’s sustained strikes on Ukraine. What follows is confined to what the verified programme record supports.
What the record confirms
The Shahed-136 is manufactured by HESA (Iran Aircraft Manufacturing Industrial Co.) and was introduced in 2021. It is a fixed-wing, delta-wing airframe classified as Group 3, with a length of 3.5 metres and a wingspan of 2.5 metres. Maximum take-off weight is 200 kg, with a maximum payload capacity of 50 kg, of which the recorded warhead itself is the stated 50 kg payload, with a reported variant carrying up to 90 kg. Maximum speed is 185 km/h, cruise speed 150 km/h, maximum range 2,000 km, and endurance is recorded at 4 hours.
Propulsion is a single piston engine, recorded as the MD-550, a reverse-engineered version of the Limbach L550E, producing 37 kW (50 hp). It is launched from a rail using a rocket-assisted booster and has no recovery method, being an expendable, one-use munition by design. Its control and autonomy level is recorded as fully autonomous waypoint navigation, and it is not satcom-capable. The airframe carries no dedicated ISR sensor payload (the munition itself is the payload), although some variants are recorded as carrying an electro-optical seeker.
Unit cost is recorded at approximately $35,000. Known operators are Iran, Russia and Houthi forces in Yemen. The verified record notes that Russia builds a locally produced version under the designation Geran-2, and that the type has been central to Russia’s strikes on Ukraine since 2022.
The record’s classification of the Shahed-136 as Group 3 places it in a lower-size category than the Group 5 long-endurance ISR and strike platforms more commonly discussed in defence AI commentary. This classification distinction is itself analytically significant: the Shahed-136’s strategic effect is achieved through low unit cost and volume of production and use, rather than through the sophisticated payload or endurance associated with larger platforms, and any assessment of the type’s impact must account for that difference in operating logic rather than treating it as a smaller version of a long-endurance strike drone.
What this does and does not establish
The verified specification confirms that the Shahed-136 is a real, mass-produced, long-range, autonomously navigating one-way attack munition with a low unit cost relative to conventional cruise missiles, and that it has been employed at scale by more than one state actor. It confirms the type’s autonomy is classified at the waypoint-navigation level rather than the munition requiring continuous human piloting.
The identified source does not provide a verified account of guidance accuracy, terminal seeker performance beyond the general note of an EO seeker on some variants, or production volume figures, and no claim is made here about those matters. It also does not establish combat effectiveness rates, interception rates, or the proportion of variants fitted with the electro-optical seeker versus those without, and none of that should be inferred from what is available.
Why it is being watched closely
Three factors explain the Shahed-136’s prominence in discussion of mass autonomous strike warfare. First, cost asymmetry: at roughly $35,000 per unit, it is priced to be employed in large numbers against targets that would otherwise require far more expensive interceptors or cruise missiles to counter, creating a persistent cost-exchange problem for any defender. Second, range and autonomy: a stated 2,000 km range combined with fully autonomous waypoint navigation allows strikes to be launched well behind the front line without a remote pilot in continuous control. Third, proliferation: recorded use by Iran, Russia and Houthi forces, plus Russian domestic production as Geran-2, indicates the design has moved from a single state’s arsenal into wider use and local manufacture.
What would change this assessment
Three categories of additional evidence would materially change what can be said about the Shahed-136 with confidence:
- Guidance and seeker detail. A primary-source technical description of terminal guidance accuracy and the prevalence of the electro-optical seeker variant across the fielded fleet, which the identified source does not quantify.
- Operational data. Verified figures on production volume, strike employment numbers and interception rates, distinguishing confirmed outcomes from contested battlefield claims.
- Independent verification. A second, independent source corroborating or updating the specification data above, since the identified source for this entry is a single reference.
Until such evidence is identified and verified, this article’s conclusions are limited to the specification and programme status set out above.
