Israel has operationally deployed Iron Beam, a 100,000-watt laser air-defense system capable of shooting down drones, rockets, and mortars at negligible per-shot cost. According to Tom's Hardware, it marks the first real-world deployment of a high-energy laser as part of a modern, multi-layered missile defense network. From the report: The Iron Beam is a short-range line-of-sight laser interceptor that is extremely cheap to run and, therefore, perfectly suited for intercepting low-cost, high-volume threats. According to the official Israeli announcement, Iron Beam systems have "successfully intercepted rockets, mortars, and UAVs." A complex mix of government, military, scientific, and commercial interests were responsible for the research and development of the Iron Beam laser system. Central to the Iron Beam are "an advanced laser source and a unique electro-optical targeting system, enabling the interception of a wide range of targets at an enhanced operational range, with maximum precision and superior efficiency," boasted the press release by Israel's MoD. Moreover, it works "at a negligible marginal cost, which constitutes the laser system's primary advantage." We don't get much more by way of technical details, perhaps understandably. However, Rafael Advanced Defense Systems execs heralded the system's "unique adaptive optics technology," in what it calls "the world's most advanced laser-based system for intercepting aerial threats." Its operational debut "marks the beginning of the era of high-energy laser defense," they claimed. Read more of this story at Slashdot.
