“Shahed drone” gets used as a catch-all term, but it actually describes an expanding family of distinct aircraft with meaningfully different capabilities, roles, and guidance systems. Understanding the lineup matters, because the newest variants represent genuine design evolution, not simply more of the same airframe.
The Baseline: Shahed-136 and Shahed-131
The Shahed-136 is the variant most people picture when they hear the name — a delta-wing loitering munition launched from angled racks mounted on trucks or trailers, requiring no runway or prepared airbase, navigating via satellite positioning and onboard inertial guidance to a pre-programmed target. It first demonstrated its strategic relevance publicly in the 2019 Abqaiq-Khurais attacks on Saudi oil infrastructure, and became globally familiar after 2022, when large numbers were transferred to Russia and redesignated Geran-2 for sustained use against Ukrainian infrastructure. The smaller Shahed-131 shares the same basic design philosophy at a reduced scale.
The Newest Evolution: Going Electric
In March 2026, analysts identified a new electric-propulsion variant of the Shahed-101, using battery power instead of the small piston engines that give earlier Shahed models their distinctive engine drone. The design tradeoff is straightforward: reduced acoustic signature during low-altitude attack profiles, at the cost of some range compared to fuel-powered variants — reportedly still up to around 1,500 kilometers, carrying a warhead in the 5 to 8 kilogram class, smaller than the Shahed-131’s payload but still capable of damaging radar arrays, communications infrastructure, and other exposed, sensitive equipment. The shift to electric propulsion is a direct response to how effectively acoustic and simple visual detection have worked against the earlier, noisier variants — a real technical adaptation, not just an incremental update.
The Extremes: Shahed-149 and Shahed-147
At the larger end of the family, the Shahed-149 “Gaza” is a substantially bigger aircraft — a reported 21-meter wingspan, up to 2,500 kilometers of range, capable of carrying up to 13 munitions or roughly 500 kilograms of payload, with an endurance around 24 hours. That endurance and payload profile pushes it closer to a persistent strike and surveillance platform than a simple one-way loitering munition. The Shahed-147, unveiled at a military exhibition with a reported 26-meter wingspan, is described as capable of reaching altitudes around 60,000 feet — comparable to the operating altitude of the US RQ-4 Global Hawk — positioning it more as a high-altitude, long-endurance surveillance platform than an attack drone in the traditional Shahed mold.
Guidance Is Getting More Sophisticated Too
The newest turbojet-powered variant, the Shahed-238, reportedly offers a choice of guidance packages — satellite navigation, electro-optical terminal guidance, or radar-homing — the latter suited specifically to suppression-of-enemy-air-defense missions, where the drone homes in on an active radar emission rather than a fixed pre-programmed coordinate. That’s a meaningfully different mission profile than the original Shahed-136’s simple point-to-point strike, and it reflects an active, iterating weapons program rather than a single design being produced unchanged at scale.
What the Product Line Says About the Manufacturing Philosophy
The breadth of this lineup — from a simple $20,000-class strike drone up to a 24-hour-endurance, half-a-tonne-payload persistent platform, all under variations of the same family name — reflects a deliberate design philosophy rather than scattered experimentation. Iran’s drone program has consistently prioritized rapid, low-cost iteration and mass producibility over the kind of individually exquisite engineering that characterizes most Western strike drone programs. Each new variant tends to reuse airframe and production techniques from earlier models while changing propulsion, guidance, or payload to address a specific operational gap identified in prior use — the electric Shahed-101 answering the acoustic-detection problem, the radar-homing Shahed-238 answering the suppression-of-air-defense mission specifically, the larger Shahed-149 answering a demand for longer-endurance persistent strike capability. That iterative, needs-driven production model is arguably as significant to understanding the program’s trajectory as any single variant’s individual specifications.
Why the Family Tree Matters
Treating every Iranian loitering munition as “a Shahed” the way the term gets used casually flattens a genuinely evolving weapons program into a single static threat — which understates both how the design is adapting to counter-measures already fielded against it, and how differently the various roles within the family need to be defended against. A radar-homing Shahed-238 aimed at air defense radar and a slow, quiet, battery-powered Shahed-101 aimed at soft infrastructure are different problems for a defender, even though both get reported under the same name.
