Singularity Defense is a stealth startup based in El Segundo, CA of former SpaceX, Anduril, and Lockheed applying the SpaceX model to mass produce air defense systems. They’re backed by Gen HR McMaster and just closed out their seed funding round from several major SV firms. Their first product is a low-cost air defense system for immediate deployment around the world starting with Ukraine where the need is critical.
