First Operational Use and Combat Deployment
The Shahed 136 first made headlines in 2019 when it was reportedly used in a strike on a Saudi oil facility, an incident that exposed vulnerabilities in high-value infrastructure to drone attacks. Officially, it entered service with Iran’s armed forces in 2021, but by 2022, large shipments were sent to Russia, where it was rebranded as the Geran-2. Russia has since deployed the Shahed 136 extensively during the Ukraine conflict, often targeting critical energy and civilian infrastructure.
Design Overview: Structure and Propulsion
The Shahed 136 features a delta-wing airframe, bearing resemblance to the smaller Shahed 131 model, though it is differentiated by its wingtip stabilizers for enhanced flight stability.
It is powered by a MADO MD-550 piston engine, an unlicensed Iranian replica of the German Limbach L550E, delivering around 50 horsepower. The engine is mounted at the rear, giving the drone a pusher-propeller configuration, propelling it forward at speeds up to 185 km/h.
Range, Speed, and Altitude
While exact range figures remain classified, various estimates suggest the Shahed 136 can fly between 1,000 km and 2,500 km, offering considerable operational flexibility. Its maximum flight ceiling is approximately 4,000 meters (13,000 feet)—high enough to evade low-tier air defenses but within range of modern radar systems.
Explosive Payload and Warhead
Equipped with a high-explosive fragmentation warhead, the Shahed 136 carries between 36 kg to 50 kg of explosives. Its destructive power surpasses that of a 155 mm artillery shell, making it capable of causing significant damage to stationary ground targets such as power stations, warehouses, and command centers.
Guidance System and Navigation
The drone uses a simple inertial navigation system (INS) combined with consumer-grade GPS to guide it toward pre-designated coordinates. It lacks any form of real-time remote control, which limits its use to fixed, non-mobile targets. However, this simplicity reduces its cost and makes it less vulnerable to electronic countermeasures.
Notably, Russian versions (Geran-2) are believed to feature GLONASS satellite navigation, offering improved accuracy over Iran’s baseline version.
Launch Mechanism and Mobility
The Shahed 136 is launched from a multi-drone rack system, typically mounted on military or commercial trucks. Each rack can hold up to five drones, which are launched using rocket-assisted take-off, giving them initial thrust to become airborne nearly horizontally. When covered, these trucks resemble standard logistical vehicles, aiding in concealment and mobility.
Components and Supply Chain Circumvention
Analyses of downed Shahed 136 drones in Ukraine have uncovered the use of Western and Chinese components, including processors from Altera Corporation (USA). Despite international sanctions, Iran has managed to circumvent technology embargoes, integrating restricted parts into its drone programs—highlighting gaps in global export controls.
Operational Effectiveness and Battlefield Impact
Strengths
- Inexpensive to produce and deploy: Estimated cost ranges from $20,000 to $50,000 per unit.
- Swarm tactics: When used in groups, these drones can overwhelm enemy air defenses.
- High cost-effectiveness: Shooting down a single Shahed 136 often requires missiles that are many times more expensive.
Weaknesses
- Not stealthy: The loud piston engine emits a sound similar to a moped or lawnmower, giving it the nickname "flying moped" in Ukraine.
- Slow and vulnerable: Its speed and flight profile make it susceptible to modern air defense systems.
- Limited against military targets: Primarily useful against fixed infrastructure, rather than mobile units or armored formations.
Role in the Russia-Ukraine Conflict
Russia’s acquisition of over 2,400 Shahed 136 drones in 2022 marked a significant uptick in their usage. The Geran-2 was heavily deployed against Ukrainian civilian infrastructure, particularly electrical power plants, in an attempt to cripple the country’s energy grid. Despite Ukrainian air defenses intercepting approximately 85% of these drones, several still penetrated through to cause significant damage, proving the danger of mass deployment tactics.
Psychological and Strategic Warfare
The loud, persistent buzzing of the Shahed 136 creates a psychological impact on civilians and military personnel alike. Its low cost allows it to be expendable, forcing defenders to use expensive SAMs (surface-to-air missiles) on low-value targets—a war of attrition tactic favoring the attacker.
Moreover, its proven ability to saturate air defense systems creates windows of opportunity for follow-on strikes by cruise missiles or manned aircraft.
Variants and Modifications
- Geran-2 (Russian variant): Features GLONASS-based navigation and slightly modified internal components to suit Russian operational needs.
- Future upgrades: May include improved navigation systems or integration into more sophisticated swarm attack strategies.
