Shahed Drone
Overview
The Shahed Drone (샤헤드 드론) is a series of one-way attack drones (loitering munitions) developed by Iran's state-owned aerospace company, Iran Aircraft Manufacturing Industries (HESA). 'Shahed' means 'witness' or 'martyr' in Persian. These drones, with their low cost and simple structure enabling mass production, have introduced a new paradigm on the modern battlefield. They gained global attention especially after Russia's invasion of Ukraine in 2022, when the Russian military adopted them on a large scale.

Development Background
The Shahed drone began development in the early 2010s as part of Iran's indigenous defense industry advancement strategy. Despite long-term international sanctions, Iran has developed advanced weapon systems domestically, particularly excelling in drone technology. The Shahed series is based on existing reconnaissance drone technology, enhanced with attack capabilities, designed to strike key enemy infrastructure at low cost.
Major Models
- Shahed-136: The most widely known model, a small drone with a delta-wing shape. It is approximately 3.5m long, with a wingspan of 2.5m, weighing about 200kg, and carries a 40–50kg warhead. Its range is estimated at 1,000–2,500km, using GPS and inertial navigation system (INS) for precision strikes.
- Shahed-131: A smaller model than the Shahed-136, with a range of about 900km and a warhead weight of 15–20kg. It is primarily used for short-range strikes.
- Shahed-238: The latest model, equipped with an infrared seeker to track moving targets. It also uses a jet engine, boasting higher speeds (up to 500km/h).
Operational Method
Shahed drones operate in a 'one-way attack' mode. That is, they are not recovered after launch but crash into the target and self-destruct. This is similar to cruise missiles, but they are much cheaper (approximately $20,000–$50,000 per unit) and can be mass-produced. The drones fly along pre-programmed routes, with mid-course corrections via GPS and inertial navigation. Launchers are mounted on trucks or ships for mobile operation, and multiple drones can be launched simultaneously.
Tactical Features
- Swarm Attack: The tactic of launching multiple Shahed drones simultaneously to saturate enemy air defenses is commonly used. Their low cost allows for mass deployment, effectively exhausting expensive air defense missiles.
- Low-Altitude Penetration: They fly at low altitudes (about 100–300m) to evade radar detection. Their small size and slow speed (about 180km/h) also make them difficult for existing air defense systems to detect.
- Night Operations: They are more effective at night due to low noise and small thermal signature.
Impact
Shahed drones have been used in the Russo-Ukrainian War to attack Ukraine's power grid, substations, and military bases, causing significant damage. In response, Ukraine introduced Western air defense systems (e.g., NASAMS, IRIS-T), but complete defense has been difficult due to the low cost and mass production capability of Shahed drones. These drones have also been used in the Middle East, such as by Yemen's Houthi rebels to attack Saudi Arabian oil facilities.
Latest Trends
Since 2024, Shahed drone technology has continued to advance. Iran has introduced jet engines in the Shahed-238, improving speed and maneuverability, and equipped it with an infrared seeker to enhance strike accuracy against moving targets. Additionally, Russia, through cooperation with Iran, has established its own production line, mass-producing Shahed drones under the name 'Geran-2'. In 2025, the use of Shahed drones on the Ukrainian battlefield is expected to increase further, prompting Ukraine to focus on developing electronic warfare systems and laser weapons. The international community is also strengthening sanctions to limit Iran's drone technology exports, but this has not fully prevented the spread of the technology.
