Iron Beam (Hebrew: קֶרֶן בַּרְזֶל, keren barzel), officially מגן אור, magen or, "Light Shield" is a directed-energy weapon air defense system unveiled at the Singapore Airshow on February 11, 2014 by Israeli defense contractor Rafael Advanced Defense Systems. The system is designed to destroy short-range rockets, artillery, and mortar bombs; it has a range of up to 7 km (4.3 mi), complementing the Iron Dome system which was designed to intercept missiles launched from a greater distance. In addition, the system could also intercept unmanned aerial vehicles (UAVs). Iron Beam will constitute the fifth element of Israel's integrated missile defense system, in addition to Arrow 2, Arrow 3, David's Sling and Iron Dome.

Characteristics

Iron Beam uses a fiber laser to generate a laser beam to destroy an airborne target. Whether acting as a stand-alone system or with external cueing as part of an air-defense system, a threat is detected by a surveillance system and tracked by vehicle platforms in order to engage. The main benefits of using a directed energy weapon over conventional missile interceptors are lower costs per shot, unlimited number of firings, lower operational costs, and less manpower. There is also no interceptor debris to fall on the area protected. The cost of each interception is negligible, unlike expensive missile interceptors—around US$2,000 per shot to cover all costs, against $100,000 to $150,000 per interceptor firing.

In 2016 laser power levels were reported to be "tens of kilowatts". While official information is not available, a 2020 report said that Iron Beam was thought to have a maximum effective range of up to 7 km, and could destroy missiles, UAVs (drones), and mortar shells around four seconds after the twin high-energy fiber-optic lasers make contact with their target. By 2023, energy levels could reach 100 kW or more and the system could focus a beam to the diameter of a coin at a distance of 10 km (6.2 mi).

As of 2016 Iron Beam had been funded mainly by the Israeli Ministry of Defense (MoD), with Rafael pursuing increasing the range of the system and partnering with other companies to further develop the prototype. In December 2022, Rafael and Lockheed Martin announced a joint effort to develop a laser defense system based on the Iron Beam project. The aim is to produce a system made up of a pair of solid-state lasers that, when combined, could boost power up to 300 kW, as well as to use more than one beam to simultaneously burn more than one target at once.

Development

Based on five years of research and development in solid-state lasers, the system is developed by Rafael, funded by the Ministry of Defense, and underwritten by the United States. An Iron Beam battery is composed of an air defense radar, a command and control (C2) unit, and two HEL (high-energy laser) systems. It was intended to be mobile and to be able to be used standalone, but was later rendered non-mobile to address weight and power availability concerns and integrated into Iron Dome to reduce complexity. It is intended for two laser guns to initially produce 100 to 150 kW of power.

In April 2022, the Israeli Ministry of Defense and Rafael announced that in a series of experiments the system successfully shot down drones, rockets, mortar bombs, and antitank missiles. The military pushed for an earlier deployment, possibly due to concerns that there would not be sufficient Iron Dome projectiles to combat attacks; Prime Minister Naftali Bennett said in February 2022 that Israel would deploy the system within the year. However, in October 2022 Rafael said it expects to take "two to three years" to deploy the 100-kW weapon operationally.

In May 2023, Rafael unveiled the Naval Iron Beam meant for installation on ships. The system is designed to emit 100 kW out to "several kilometers" to protect vessels against drone swarms and anti-ship missiles. The naval version maintains the same turret external dimensions and can be configured to be integrated onto ship superstructures or in containerized modules to be embarked when needed. The Naval Iron Beam is planned to be operational within four to five years and first be fitted to the Israeli Navy's Reshef-class corvette.

In October 2023, the Ministry of Defense and Rafael announced they would be deploying the Iron Beam to the southern border with the Gaza Strip to deal with countless rocket fire from Hamas, because of the ongoing conflict.
