Iron Beam

Rafael Advanced Defense Systems’ Iron Beam is a 100-kilowatt-class solid-state laser air defence system declared operational by Israel in 2025. It is intended to handle the short-range threats — mortars, rockets, anti-tank missiles, and one-way attack drones such as Iran’s Shahed-136 — that have made the Iron Dome interceptor stockpile increasingly costly to sustain. Where a Tamir round runs in the tens of thousands of dollars, an Iron Beam shot costs the price of the electricity needed to charge the system’s power supply; Rafael has long quoted figures of a few dollars per engagement.

The system pairs a high-energy solid-state laser with a beam director and tracking optics that lock onto a target cued by external radar. In Israeli service it draws targeting data from the same command-and-control fabric that runs Iron Dome — Elta’s EL/M-2084 multi-mission radar — meaning the laser slots into existing batteries rather than standing up a separate kill chain. Effective range sits under ten kilometres and depends heavily on atmospheric conditions: cloud, dust, and rain absorb laser energy, and Israeli trials have explicitly tested degradation curves in Negev desert and Mediterranean coastal weather. Continuous-fire capacity, limited only by power and cooling, is the system’s main attraction against drone swarms that exhaust finite missile magazines.

Israel’s Ministry of Defense signed a contract worth roughly two billion shekels — around 500 million dollars — with Rafael and Elbit Systems in late 2024 for accelerated delivery of operational batteries, with Elbit supplying the laser source. Earlier live-fire trials in 2022 and again in 2024 demonstrated intercepts against mortars, rockets, anti-tank missiles, and quadcopters. Israel has stated its intent to integrate Iron Beam into the multi-tier air defence array alongside Iron Dome, David’s Sling, and Arrow, with the laser shouldering the cheapest threats so the missile interceptors can be reserved for harder targets.

Naval and vehicle-mounted variants are under development. A lower-power mobile version, displayed at international shows as Lite Beam, has been pitched for export and trialled against drones — Rafael has reported interest from European operators concerned about the cost of intercepting Russian-style Shahed strikes against Ukrainian and, potentially, NATO infrastructure. The system enters a crowded field of Western directed-energy programmes, including the US Army’s DE-MSHORAD, the United Kingdom’s DragonFire, and Lockheed Martin’s HELIOS, but Iron Beam is the first high-energy laser to cross from demonstrator to declared operational status in a country actively under sustained drone and rocket fire.
