Defense Sensors and Comms Companies in the United States

Radar, passive RF sensing, tactical networks and mesh radios. Every autonomy and counter-drone program depends on them, and the push to link sensors to shooters across the services has made resilient communications a funding priority. Together they have disclosed $1.1B in funding, led by Chaos Industries (~$930M). The newest round on record is Austin Sensing Company's Seed (Oct 2026).
