"Rare earths are crucial for various defense technologies, including F-35 fighter jets, Virginia- and Columbia-class submarines, Tomahawk missiles, radar systems, Predator unmanned aerial vehicles, and the Joint Direct Attack Munition series of smart bombs. The United States is already struggling to keep pace in the production of these systems."

This feels like it can't be true. What % of "rare earths" are going into those military products? I mean those are super low volume manufacturing compared to EVs or anything consumer oriented. I'm sure there are strong magnets somewhere in a submarine but how many?

I thought "rare earths" were not rare at all. A lot of stuff is made in China because it's economical but can be made somewhere else for a bit more money. Do billion dollar fighter jets care if the magnet used in some electric motor costs $0.35 or $0.43 ?

Isn't the manufacturing issue in the US unrelated to any of this? Not enough factories, not enough skilled people, not having ramped up because munitions weren't needed?
