Counter-Drone Companies in the United States
Counter-UAS companies detect, track and defeat hostile drones with radar, RF sensing, jamming, guns, microwave weapons and interceptor drones. Drone incursions over US bases and attacks on US troops in the Middle East have made it one of the most urgent buying priorities for the military and for homeland security. Together they have disclosed $271M in funding, led by Allen Control Systems (~$242M). The newest round on record is Fortem Technologies's Series B (Sep 2026).
