Watch: Israel deploys iron beam for first mid-air rocket interception- how the system works

Iron Beam marks new era of warfare (Representative image)

Hezbollah launched a wave of strikes across the Middle East late on Sunday, triggering interceptions over Israeli territory by the country’s advanced air defence systems. The escalation followed a dramatic development a day earlier — the killing of Iran’s Supreme Leader Ayatollah Ali Khamenei and several senior figures in Tehran.

In the aftermath of Khamenei’s death, the Lebanon-based militant group intensified its military response, vowing retaliation for the killing of the influential Shia leader. Hezbollah targeted what it described as hostile sites, firing rockets and projectiles at Israel, a key partner in the United States’ most ambitious regional military campaign against Iran — strongly backed by Donald Trump.

A video released by the Israel War Room showcased interceptions in real time, describing the Iron Beam as marking a “new era of warfare” for the country’s defences. The footage appeared to show incoming projectiles lighting up the night sky before being neutralised mid-air. According to the Israel War Room, this represented the “first-ever use” of the Iron Beam system.

The broader military campaign between Washington and Tel Aviv has been conducted under what the US termed Operation Epic Fury, while Israel has referred to its strikes as Operation Lion’s Roar.

Alongside its emerging laser technology, Israel continues to rely on its established layered air defence network — particularly the Iron Dome — which remains central to protecting civilian areas from short-range rocket fire.

Layered protection: How Israel’s air defences operate

Israel’s air defence architecture is built on multiple systems designed to counter different types of aerial threats.

Iron Dome — intercepting rockets and projectiles

The Iron Dome is Israel’s mobile missile defence system designed to intercept short-range rockets, artillery shells, drones and mortar fire.

It works through three main stages:

Radar detection – Sensors track incoming projectiles and calculate their trajectory.

Control assessment – Command systems estimate whether the threat is likely to hit populated areas.

Interceptor launch – If deemed necessary, a kinetic interceptor missile known as Tamir is fired to destroy the target mid-air.

The system typically covers a range of roughly 4km to 70km and is designed to engage threats only when they pose a risk to strategic or civilian infrastructure. Each interception costs tens of thousands of dollars per shot, but it is considered highly effective in dense attack scenarios.

Iron Beam,  the laser-based “game-changer”

Israel has also been accelerating development of its newer laser-based system, the Iron Beam.

This week, Israel signed contracts worth more than $500 million with domestic defence firms Rafael Advanced Defense Systems and Elbit Systems to expand production of the system, signalling confidence in its future role within the broader defence network.

First unveiled in 2014 and declared operational after final testing in September, the Iron Beam is designed to neutralise smaller aerial threats such as drones, rockets and mortars. Israeli officials have described it as potentially ushering in “a new era of warfare”.

Unlike traditional missile interceptors, the system uses a directed-energy laser beam to disable targets. As long as power is available, it does not require physical ammunition — a feature that officials say could make it far more cost-effective than firing repeated interceptor missiles.

The system is not intended to replace platforms such as Iron Dome, David’s Sling or the Arrow missile defence system. Instead, it complements them by engaging smaller threats, allowing more advanced systems to focus on long-range or complex missiles.

However, the technology has constraints. Laser-based interception can be less effective in poor visibility conditions such as heavy cloud cover, dust storms or adverse weather, which may scatter or weaken the beam.

Wider military backdrop

The latest escalation follows what Washington described as its most ambitious joint military operation with Israel aimed at weakening or potentially dismantling the Tehran regime.

The United States has dubbed its campaign Operation Epic Fury, while Israel’s concurrent strikes have been carried out under the name Operation Lion’s Roar.

The confrontation marks a new phase in regional conflict dynamics, with advanced defensive technologies now playing a visible role in live combat conditions. As missile exchanges intensify, Israel’s reliance on layered interception — combining kinetic missiles with emerging laser systems — is becoming central to its security posture.
