Perseus Defense
Perseus Defense is building a mass-manufactured Counter UAS solution for the Department of Defense and Department of Homeland Security. Current solutions are one-to-one, too dangerous for use on U.S. soil, and orders of magntiude more expensive than the threats they defeat. Our self-guided missile platform is man-portable and multi-domain capable. It senses, engages, and eliminates threats with drastically reduced cost per engagement over existing kinetic solutions.

Guardian RF
match 65The rise of low-cost commercial drones has introduced a new class of asymmetric threats to U.S. national security. Off-the-shelf platforms now deliver ISR, contraband, or payloads with precision, while operating below radar coverage and beyond line-of-sight. These systems—often costing under $1,000—are capable of neutralizing multi-million-dollar defense assets. For drone detection to be viable at scale, sensors must achieve cost parity with the threat. In response, the Department of Defense est
