As fusion startups keep chasing their ultimate goal — putting electrons on the grid — many are also now embracing, or returning to, the defense applications that laid the foundation for the industry. The sector emerged decades ago when physicists looked for more constructive uses of the science behind the thermonuclear bombs that proliferated during the Cold War. The national security angle never really went away. A groundbreaking fusion power experiment in 2022 happened at the National Ignition Facility, which has supported national security applications for more than 25 years. That shift has accelerated as venture dollars committed to climate tech — the funds that typically have supported fusion startups — have stalled. Fusion startups have captured a large portion of recent climate tech funding, but fusion is an expensive business, and VCs are always happy when their portfolio companies find other sources of money. That’s where the defense industry comes in. The defense industry has explored laser weapons for years, but interest has spiked as drones have reshaped modern warfare. Traditional air defense systems were designed to target human-piloted aircraft, which tend to be larger and fewer in number. That has led to some comical mismatches between aggressor and defender. For example, about a decade ago, a U.S. ally used a $3 million Patriot missile to shoot down a $200 consumer drone. Effective, but not very efficient. Laser weapons promise to alter the math. Instead of firing a single, expensive, one-use missile per shot, hey fire quickly and relatively cheaply, using electricity drawn from a generator or a ship’s reactor or engine. Fusion startups working on laser-based reactor designs are ideal partners in developing such weapons. Last week, laser-based fusion startup Xcimer announced a partnership with and investment from RTX, the conglomerate that includes defense contractor Raytheon. Under the deal, Xcimer gets funding from RTX Ventures, while RTX can start exploring how to use Xcimer’s powerful lasers for its own purposes.
