The Iron Dome is an advanced, mobile all-weather air defense system developed by Rafael Advanced Defense Systems and Israel Aerospace Industries (IAI). It is designed to intercept and destroy short-range rockets, artillery shells, and mortars (SRAM) fired from distances of 4 to 70 km. Here’s a detailed breakdown of its technical aspects and other relevant details:
Technical Data
- Manufacturer: Rafael Advanced Defense Systems (Israel)
- Type: Short-range air defense system (SRAD)
- First Deployment: 2011
- Components:
- Detection and Tracking Radar: Manufactured by Elta, the radar system detects and tracks incoming projectiles.
- Battle Management & Weapon Control (BMC): Developed by mPrest Systems, the BMC calculates the projectile’s trajectory and determines if it poses a threat.
- Missile Interceptor (Tamir): The interceptor missile is used to neutralize threats. It has a high level of maneuverability and electro-optical sensors for accurate interception.
- Range:
- Effective against threats up to 70 km (43 miles).
- It can handle both single and mass rocket salvos.
- Response Time: Approximately 15 seconds from detection to interception.
- Radar System: EL/M-2084 Active Electronically Scanned Array (AESA) radar.
- Number of Batteries:
- One Battery: Covers about 150 square kilometers.
- Each battery includes three to four launchers, and each launcher holds 20 interceptors.

Price
- Unit Price: The cost of a single Iron Dome battery is approximately $50 million.
- Tamir Interceptor Cost: Each interceptor missile costs about $40,000 to $100,000, depending on specific configurations and quantities.
- Annual Operating Cost: The operational cost of maintaining Iron Dome varies but can reach hundreds of millions of dollars annually, depending on the intensity of use.
Capabilities
- Interception of Various Threats: Iron Dome is effective against rockets, artillery shells, and mortar bombs. It can also intercept unmanned aerial vehicles (UAVs) and has been adapted to counter cruise missiles and other precision-guided munitions.
- Mobile and Rapid Deployment: The system is mobile and can be quickly redeployed to protect specific areas. Each battery can be operational within hours.
- Selective Targeting: Iron Dome can differentiate between projectiles heading toward populated areas and those heading toward uninhabited regions. It prioritizes intercepting only the rockets that pose a threat to populated areas or critical infrastructure.
- Multi-layered Defense: The Iron Dome serves as part of Israel’s multi-layered missile defense system, which includes David’s Sling (mid-range) and the Arrow system (long-range ballistic missile defense).
Advantages
- High Success Rate: Iron Dome boasts a success rate of around 90% in real combat conditions. This figure may vary slightly, but the system has proven its effectiveness in protecting Israeli civilian and military areas.
- Cost-effective for High-threat Areas: In areas subjected to frequent short-range rocket and missile attacks (such as southern Israel near Gaza), the system has proven invaluable in reducing casualties and property damage.
- Minimal Collateral Damage: The interceptor missile self-destructs if it misses the target, minimizing the risk of falling debris or unintended damage.
- Protection of High-value Assets: Protects critical infrastructure like power plants, military bases, airports, and civilian populations.
- Psychological Effect: The Iron Dome has provided a sense of security to civilians, reducing the panic associated with incoming rocket attacks.
Disadvantages
- High Cost of Interception: Each interception costs between $40,000 to $100,000, which can be expensive compared to the relatively low cost of the incoming projectiles, some of which can cost as little as a few hundred dollars.
- Overwhelming Swarm Attacks: While Iron Dome is highly effective, it could potentially be overwhelmed if subjected to large-scale simultaneous missile or rocket salvos beyond its handling capacity.
- Not Effective Against Ballistic Missiles: Iron Dome is designed for short-range threats, and while it is part of Israel’s multi-layered defense, it is not effective against medium- or long-range ballistic missiles, which are handled by other systems like David’s Sling or Arrow.
- Limited Coverage Area: One Iron Dome battery can only protect a limited area of approximately 150 square kilometers. Multiple batteries are required to defend larger regions, adding to the cost.
User Countries
- Israel: The Iron Dome system was developed for and is primarily used by the Israel Defense Forces (IDF). It has become a crucial part of Israel’s air defense, particularly along its borders with Gaza and Lebanon.
- United States: The U.S. has shown interest in the system, purchasing several batteries to protect its military bases and use for testing. The U.S. Army deployed two Iron Dome batteries.
- Azerbaijan: In 2016, it was reported that Azerbaijan had purchased the Iron Dome system from Israel, adding it to its defense arsenal.
- India: India expressed interest in purchasing the Iron Dome system to defend its borders against potential threats from Pakistan and other adversaries, but so far, no official procurement has been confirmed.
- Romania: In 2021, Romania announced plans to acquire Iron Dome to enhance its national air defense capabilities.
- Other Countries: Several countries, including South Korea and Singapore, have shown interest in Iron Dome technology, and there may be ongoing negotiations or future purchases.
Conclusion
The Iron Dome system is a highly advanced air defense system, providing a critical layer of protection against short-range projectiles. Its strength lies in its ability to intercept threats with high accuracy and differentiate between dangerous and non-threatening projectiles. However, its high operational costs and vulnerability to massive simultaneous attacks are notable limitations. Nonetheless, the system has demonstrated its effectiveness in protecting civilian populations, making it a valuable defense tool in conflict zones.
