Startups developing nuclear fusion technology are increasingly returning to their defense roots, forging partnerships with military contractors to secure vital funding as climate tech venture capital slows down. This strategic shift is largely driven by the growing demand for directed-energy weapons, such as high-power lasers, which offer a cost-effective alternative to traditional missiles when countering modern threats like swarming drones.
Prominent startups are already capitalizing on this trend. Xcimer has secured funding and a partnership with RTX to explore laser applications, while Pacific Fusion is collaborating with government security agencies on high-energy-density experiments. These alliances provide startups with essential capital and advanced testing grounds, whereas defense contractors gain cutting-edge technological capabilities.
By reconnecting with the defense sector, the capital-intensive fusion industry gains a reliable financial buffer reminiscent of its Cold War origins. Moving forward, these dual-use innovations are expected to accelerate both national security capabilities and the ultimate realization of commercial fusion energy.
