Defense contractor RTX is collaborating with fusion startup Xcimer to explore the potential of high-powered laser technology, initially designed for fusion energy, to be adapted into directed-energy weapons. This partnership represents a significant dual-use spillover, where commercial fusion research and development funding could accelerate military laser capabilities and vice-versa, echoing Cold War-era programs.
This collaboration specifically targets the urgent need for counter-missile and counter-drone systems, an area of high military interest given the proliferation of inexpensive drones. The initiative revives Cold War-era thinking about high-energy lasers, demonstrating how fusion research can serve both civilian energy and military defense purposes.
The strategic investment by RTX in Xcimer Energy aims to leverage a single, groundbreaking laser technology for two ambitious goals: powering the national grid with commercial fusion energy and creating a new class of directed energy weapons for air defense. This dual-use strategy is expected to create a powerful feedback loop, accelerating development in both critical areas. Xcimer's excimer-based laser technology, historically used in semiconductor manufacturing and LASIK eye surgery, is being advanced to unprecedented power and efficiency levels, addressing the core challenge in both laser fusion and laser defense: building a reliable, cost-effective, high-repetition-rate laser.
