Prox
Air-breathing hypersonics for scale.
Parity is a moving target. Every advance in offense prompts a response in defense, and every response starts another race. The West cannot take military superiority for granted. It has to keep building, fielding, and improving technology at scale. We believe hypersonics at scale can be the West's ultimate equalizer. Our mission is to give the United States and its allies the capacity to close capability gaps and sustain credible deterrence as threats evolve. Prox is developing a stand-in attack weapon platform powered by solid-fuel ducted ramjet propulsion (SFRJ), with repeatable production at the center of the effort.
