100,000-Watt Iron Beam laser becomes world’s first drone defense zapper to be operationally deployed — it can also shoot down rockets, mortars, and other aerial threats

Israel deployed its first iron beam laser defense system on Sunday. This 100kW laser weapon thus becomes the world’s first operational high-power drone defense destroyer. The Iron Beam laser will strengthen Israel’s multi-layered defenses, complementing the existing Iron Dome, David’s Sling and Arrow system architecture.

IronBeam is a short-range line-of-sight laser interceptor that is extremely cheap to operate, making it ideal for intercepting low-cost, high-volume threats. According to an official Israeli statement, the Iron Beam system “successfully intercepted rockets, mortars and drones.”

A complex mix of government, military, scientific, and commercial interests is responsible for research and development of iron-beam laser systems. The Israeli Defense Ministry boasted in a press release that the core of the Iron Beam missile is “an advanced laser source and a unique electro-optical targeting system, capable of intercepting a variety of targets over a larger combat range with the highest accuracy and superior efficiency.” Furthermore, it works at “negligible marginal cost, which is the main advantage of laser systems.”

We don’t get much more from the technical details, which is perhaps understandable. However, executives at Rafael Advanced Defense Systems praised the system’s “unique adaptive optics technology,” calling it “the world’s most advanced laser system to intercept air threats.” Their first operational use “marked the beginning of the era of high-energy laser defense,” they claimed.

Earlier this year we saw the deployment of low-energy laser defense systems, with Japan’s NTT using relatively weak lasers to scare away birds at poultry farms and prevent the spread of avian influenza. But Tie Liang is in a different league.

We’ve previously reported on several other laser weapons being developed in the UK to counter drones on land and at sea. But as far as we know, these are not yet operational. As the brutal war between Ukraine and Russia rages on, drones have become a key feature of the conflict, with the military even erecting rotating barbed wire barriers to stop them. Therefore, laser drone defense systems similar to Iron Beam will be in strong demand.
