Neros is transforming a defense industry mired in costly, behemoth machinery—to circumvent a looming vulnerability gap, to give dismounted soldiers a fighting chance against tanks, and ultimately, to get as many humans off the battlefield as possible. While consumer technology is evolving by bounds on the smaller-cheaper-better path, U.S. defense technology wallows in the large, centralized, and wildly expensive paradigm. Our air, land, and sea machinery budget is staggering; yet these large assets can still be vulnerable to very small weapons. When swarm technology comes into its own, the asymmetry will escalate. Nowhere is the pattern more glaring than in small unmanned aerial systems (sUAS)—drones.
