Hypersonics critical for US defense.
Hargis argues hypersonics will be one of the most important capabilities in the American arsenal because they travel far and fast, are highly maneuverable and very hard to shoot down, allowing the US to hold targets at risk from long distances and fight at distance from safety. He says this is a top Department of War priority and the US is playing catch-up to China and Russia, making the hypersonics buildout a critical defense theme.

Deterrence hinges on affordable munitions production.
Hargis says deterrence is manufacturing: the key problem is not hypersonic technology but producing munitions at scale and at a cost the Department of War can afford. He notes the US lost its lead because it could not mass-produce cheaply, and Castelion is building a 1,000-acre dedicated hypersonic production facility to start producing munitions in the thousands this year.
