Iranian-designed one-way attack drone (loitering munition) with delta-wing configuration, extensively used by Russia under the designation Geran-2 in mass strikes against Ukrainian infrastructure.

Shahed-136

System Overview

What It Is

The Shahed-136 is an Iranian-manufactured delta-wing one-way attack unmanned aerial vehicle (OWA-UAV), sometimes called a loitering munition or "kamikaze drone." It is designed to be produced cheaply in large numbers and launched in saturation attacks to overwhelm air defenses. Russia designates its variant the Geran-2.

How It Works

The Shahed-136 is launched from a ground-based rail system, typically mounted on a truck chassis carrying five units. After launch, it follows a pre-programmed GPS waypoint route at low altitude to its target area. The small piston engine provides a distinctive moped-like sound. On reaching the target coordinates, the drone enters a terminal dive, detonating its warhead on impact. It has no real-time operator control or ability to re-target in flight.

Primary Capability

Long-range one-way attack against fixed targets including critical infrastructure, military positions, and energy facilities using GPS-guided terminal dive.

Combat Record / Operational History

First combat use attributed to Houthi attacks on Saudi Arabia and UAE in 2022. Russia began large-scale use of the Shahed-136 (as Geran-2) against Ukraine in September 2022, launching hundreds per month in waves targeting electrical grid infrastructure, heating plants, and civilian areas. During winter 2022-2023, Russia used Shahed-136 swarms alongside cruise missiles to systematically attack Ukrainian energy infrastructure. By early 2024, Russia was reportedly launching 2,000-3,000 Shaheds per month. Ukraine has shot down the majority (claimed 80%+ intercept rate) using a combination of mobile fire groups with machine guns, Gepard self-propelled anti-aircraft guns, and electronic warfare. Despite high intercept rates, the economic asymmetry heavily favors the attacker.

Overview

The Shahed-136, designated Geran-2 by Russia, is an Iranian-produced one-way attack drone that has become one of the most consequential weapons of the war in Ukraine. Designed as an inexpensive, mass-producible loitering munition, the Shahed-136 embodies a philosophy of overwhelming air defenses through sheer numbers rather than individual sophistication. Its delta-wing planform, simple piston engine, and GPS-guided navigation allow it to be manufactured for an estimated $20,000-$50,000 per unit — a fraction of the cost of cruise missiles.

Technical Details

The Shahed-136 features a distinctive triangular delta wing with a wingspan of approximately 2.5 meters and a total length of about 3.5 meters. It is powered by a Mado MD-550 four-cylinder piston engine producing around 50 horsepower, giving it a cruise speed of roughly 185 km/h and a range of 2,000 to 2,500 kilometers. The aircraft carries a 40-50 kg high-explosive fragmentation warhead. Navigation relies on a combination of inertial guidance and GPS, with waypoints programmed before launch. The drone is launched from a truck-mounted rail system that typically carries five units, enabling rapid salvo launches.

Combat History

The Shahed-136 first appeared in combat during Houthi attacks on Saudi Arabia and the UAE. However, it gained global prominence when Russia began mass deployment against Ukraine starting in September 2022. Russia launched waves of Shahed-136 drones, often at night, to target Ukrainian energy infrastructure during the winter of 2022-2023 in an attempt to collapse the electrical grid. The attacks caused widespread blackouts and damage to power stations, transformer substations, and heating facilities. By 2023-2024, Russia had scaled production dramatically, with monthly launch rates reportedly reaching 2,000-3,000 units. Ukraine developed a multi-layered response including mobile fire groups armed with heavy machine guns, Gepard SPAAG systems, electronic warfare units, and adapted air defense missiles, claiming intercept rates above 80%.

Proliferation and Strategic Impact

Iran has transferred Shahed-136 technology to Russia, which has established domestic production lines reportedly in the Alabuga special economic zone in Tatarstan. The system has also proliferated to non-state actors including Houthi forces and Hezbollah. The Shahed-136 represents a paradigm shift in modern warfare: it forces defenders to expend interceptors costing $100,000-$500,000+ to defeat drones worth $20,000-$50,000, creating an unsustainable cost exchange ratio. This has driven urgent development of cheaper counter-UAS solutions including directed energy weapons and low-cost interceptors.
