August 9, 2026: In order to fulfill the requirement for MIRC/Medium-Range Intercept Capability air defense, Marine forces operating in the Western Pacific now have Iron Dome batteries. Testing and training have been completed for the new American mobile Iron Dome system. The Marines have already tested Israel’s Iron Dome Tamir missiles as part of its mobile MRIC system. Existing Iron Dome missile launchers hold 20 Tamir missiles. Each 160mm-diameter Tamir weighs 90 kg and is 3 meters long. Tamir’s guidance system has a radar and a proximity fuze that detect the size and speed of a nearby target and detonate the warhead only if the right type of target, such as a drone, cruise missile, or rocket, is detected. Because of the addition of American features to destroy cruise missiles and large drones, the cost per Tamir missile rose from $50,000 to nearly $150,000. MRIC uses its Tamir missiles in conjunction with a Marine radar and command-and-control system. For MRIC, the Americans also manufactured Tamir missiles but rebranded them as Skyhunter missiles.

The Army's HEMTT (Heavy Expanded Mobility Tactical Truck) is used to transport a mobile Iron Dome system for use by the Army and the Marines. These vehicles have a diesel-electric drive, so there is plenty of power for the radar and electric motors used by an anti-aircraft system. The 8x8 HEMTT trucks are built for cross-country operations and kept pace with armored formations during the 1991 and 2003 wars. Most of the 13,000 Army HEMTTs normally haul nine tons of cargo or 2500 gallons of fuel. That’s enough capacity for a mobile Iron Dome.

Six years ago, Tamir proved its ability to down cruise missiles and drones using the Iron Dome radar and fire control system. In that test, Iron Dome systems on land and Israeli ships were integrated into a multi-layer air defense system that included David’s Sling and the Arrow ABM/Anti-Ballistic Missile system. MRIC can use other air defense search, fire control, and targeting management systems. With that, Israel began offering the Tamir missiles and launchers to customers such as the American MRIC.

Continuous Israeli upgrades of Iron Dome enabled it to shoot down various types of drones. This required some software modifications and was done at the request of the American Army. Iron Dome was already capable of shooting down aircraft and helicopters. The UAVs were often much smaller, but so are the rockets and mortar shells Iron Dome can knock down. The United States has contributed over a billion dollars to the development and procurement of Iron Dome. Periodically adding new features like this helps export sales.

The Americans were impressed, which led to the development of MRIC to support mobile combat units. Iron Dome has been in service since 2011 and has proven itself in combat. Iron Dome uses two radars to quickly calculate the trajectory of the incoming rocket and do nothing if the rocket trajectory indicates it is going to land in an uninhabited area. But if the computers predict a rocket is coming down in an inhabited area, one $50,000 Tamir guided missile is fired to intercept it. This, and the fact that the Iron Dome fire control system can track hundreds of incoming missiles at once, makes the system cost-effective. So far, Iron Dome has shot down over 800 rockets, which is about 85 percent of the rockets it calculated were headed for a populated area. The Tamir missiles are effective against rockets, mortar shells, and 155mm artillery shells. Iron Dome can also shoot down aircraft and helicopters at altitudes up to 10 kilometers/32,000 feet. Iron Dome is Israel’s principal defense against short-range rockets fired from Gaza or Lebanon. Work is underway to extend the Iron Dome's range from 70 to over 200 kilometers, but it is stalled due to budget shortages.

The MRIC radar operates differently to determine which incoming threat justifies an interceptor missile. In a combat situation, the areas to be defended often change. MRIC provides Marines or soldiers moving into a new area with protection against the most threatening rocket, artillery, or mortar fire. This gives the advancing forces an edge and demoralizes defenders.

Israel initially designed Iron Dome to only defend stationary targets. By 2014, Israel had fifteen batteries of Iron Dome and over 2,000 Tamir missiles. That was enough to shut down the Hamas effort to hit Israel with thousands of rockets. Each battery has radar, fire control equipment, and 3-4 missile launchers and costs about $37-50 million depending on how many missiles it is shipped with. With the current system, a battery with two radars and three launchers costs about $100 million and can protect an area of about 150 square kilometers.

In 2014, the American Army purchased an Iron Dome anti-rocket battery from Israel, mainly to determine if Iron Dome would be worth getting for deployment in Iraq and Afghanistan, where American troops were still stationed. This American purchase was the first export sale of Iron Dome. The Americans bought two more batteries in 2020 and 2021. Israeli efforts to export their Iron Dome anti-rocket system were slow initially but eventually succeeded with Azerbaijan, India, and several other countries placing orders. The Israeli manufacturer of Iron Dome thought this would make Iron Dome a hot export item. After all, Israel is one of the top ten weapons exporters in the world. A major reason is that most of Israel’s arms exports are combat-tested. Although the Iron Dome system had succeeded in shooting down about 85 percent of the rockets headed for Israeli populated areas, that was a unique situation. Continued success eventually made Iron Dome exportable, especially after the anti-aircraft, drone, and cruise missile capabilities were added. The Americans were willing to buy more Iron Dome systems but wanted access to the fire control source code. Israel refused because American security is less strict than Israel’s and a leak of that source code would enable an enemy to determine exploitable weaknesses in Iron Dome. This software dispute was eventually resolved.

The main problem is that Iron Dome was designed to deal with an enemy that is a terrorist organization operating out of Gaza that is basically home for Palestinian refugees who have been there for over 60 years and want nothing less than the destruction of Israel. Hezbollah, a similar organization, controls southern Lebanon and is also dedicated to the destruction of Israel, using 40,000 unguided rockets they received from Iran. This is the unique situation that Iron Dome was designed to deal with. When faced with a massive launch of rockets at once, Iron Dome is unable to shoot down all of those headed for populated areas. While the intercept rate is lower, Iron Dome has shown it can still reduce Israeli casualties and property damage. Iron Dome recently added a high-powered laser device that can knock down many rockets but at shorter ranges. MRIC may also receive the laser weapon, but it will require a large generator on the MRIC to supply power.
