Iron Dome — Surface-to-Air
Open in interactive gallery →

The Iron Dome (Hebrew: Kipat Barzel) is an Israeli all-weather short-range air-defence system — Rafael Advanced Defense Systems + IAI's principal counter-rocket + counter-artillery system + the most-engaged air-defence system worldwide. Rafael (prime) + IAI (Elta radar + control systems) developed the Iron Dome in 2007-2011 in response to repeated Hezbollah + Hamas rocket fire on northern + southern Israeli cities; service entry 27 March 2011. About 3,000 Tamir interceptors are produced annually. 10 Iron Dome batteries are deployed across Israel + the US Army has bought 2 batteries.

Each Iron Dome battery consists of: 1 × EL/M-2084 Multi-Mission Radar (Elta, X-band AESA), 1 × Battle Management + Weapons Control center, + 3-4 × launchers (each holding 20 Tamir interceptors). The Tamir interceptor is a small solid-fuel missile (length 3 m, weight 90 kg, range 70 km, ceiling 10 km). Guidance: radar command + active radar terminal homing + proximity fuze with 11 kg blast-fragmentation warhead. The system's distinguishing feature is selective engagement — its software calculates the predicted impact point of each rocket + only intercepts those projected to hit populated areas, leaving rockets falling in open fields unengaged. This cuts interceptor expenditure by 60-75%.

Iron Dome combat: as of 2026 the system has intercepted >5,000 rockets + mortars across multiple conflicts — 2012 Operation Pillar of Defense (421 interceptions), 2014 Operation Protective Edge (~735 interceptions), 2021 Operation Guardian of the Walls (1,500+ interceptions, 90% claimed kill rate), + the October 2023-present Israel-Hamas war (3,000+ interceptions through 2024). The system is the most-engaged air-defence weapon worldwide + a major Israeli export product. The US Army acquired 2 batteries in 2020 ($373 million) — the first foreign sale. South Korea, Czech Republic, + Slovakia have placed orders.

For Kids — a shorter, friendlier version

The Iron Dome is an Israeli air-defense system. It is one of the most-used air-defense systems in the world. Iron Dome batteries stop rockets, mortars, and drones aimed at Israeli cities. The system entered service in March 2011. Rafael and IAI built Iron Dome together.

Each Iron Dome battery has a special radar, a battle-management computer, and 3 to 4 launchers. Each launcher holds 20 Tamir anti-rocket missiles. The Tamir is 10 feet long and 198 pounds, taller than a person and heavier than most adults can lift. The Tamir reaches Mach 2, faster than a rifle bullet.

Iron Dome has a unique feature: smart engagement. The radar tracks each incoming rocket and computes where it will land. If a rocket is going to hit an empty field, Iron Dome lets it land harmlessly. Only rockets aimed at houses, schools, or other people are stopped. This saves a lot of expensive anti-rocket missiles.

Since 2011, Iron Dome has stopped more than 5,000 rockets and mortars. The system has worked in many conflicts: 2012, 2014, 2021, and the ongoing 2023 and later wars. The American Army has bought 2 Iron Dome batteries from Israel for testing. Iron Dome is the model for many newer short-range air-defense systems around the world.

Kids’ Questions

What is smart engagement?

When a rocket is fired at Israel, the Iron Dome radar tracks it. The computer calculates exactly where the rocket will land. If the spot is an empty field or the sea, Iron Dome does not fire. If the spot is a house, school, or other people, Iron Dome fires a Tamir missile to stop the rocket. This saves 60 to 75 percent of Tamir missiles.

Why so many Tamir missiles?

Hostile rockets are cheap; a Tamir missile is expensive (about $50,000 each). To stop thousands of rockets fired at Israeli cities, Iron Dome batteries need a steady supply of Tamirs. Rafael builds about 3,000 Tamirs per year. Iron Dome stopping a rocket that could kill 5 people is worth the Tamir's cost.

Where else is Iron Dome used?

The American Army bought 2 Iron Dome batteries in 2019 to test against rocket and drone threats. Israel is also sharing Iron Dome with European countries facing Russian threats. Many countries are now building their own Iron Dome-like systems. The American Army's new IFPC system is one example, based on lessons from Iron Dome.

Frequently Asked Questions

How does Iron Dome decide which rockets to intercept?

The EL/M-2084 radar tracks each incoming rocket from launch + the Battle Management computer calculates its predicted impact point within ~2 seconds, using ballistic trajectory algorithms + Israeli terrain data. The system then queries a populated-area database (the Israeli electrical-grid + infrastructure GIS dataset) + classifies each rocket: 'urban impact' → intercept, 'open field impact' → ignore. This selective engagement saves 60-75% of interceptor cost — Tamir missiles cost ~$50,000 each, while incoming Qassam rockets cost ~$800 — so without selective engagement the cost-exchange ratio would be unfavourable. The 2012-2024 combat-data shows ~5,000 interceptions out of ~30,000 launches, with claimed kill rate ~90% on engaged threats.
