This has direct implications for defence industries, given the use of REEs in F-35 fighter jets, Virginia-class submarines, and Arleigh Burke destroyers. An F-35 fighter jet incorporates approximately 418 kg of REEs. These materials are critical for the jet’s guided missile systems, as well as the high-powered lasers used to identify and lock onto targets. The reliance on REEs ensures the F-35 maintains its edge in stealth, targeting, and flight performance.
