counter-drone
(14)
Motorola Solutions wants the whole emergency.
The radio was the starting point. Now Motorola Solutions is connecting the call, the camera and the case file - and making a costly bet on everything in between.
CACI makes the invisible useful.
A company built around a simulation language now works across drone defense, space sensors, and government software. Its big wager: customers will pay more for an outcome than an hour.
Dedrone makes the sky harder to sneak through
A fence is a splendid invention until the intruder flies over it. Dedrone turns the air above airports, stadiums and cities into something security teams can finally read.
Vector Sells the Pentagon a Subscription to Modern Warfare
A 14-month-old drone maker out of Salt Lake City wants to sell the U.S. military warfare the way Adobe sells Photoshop - as a service, updated constantly, billed like a subscription.
Greypoint Industries
Greypoint Industries is a Y Combinator S26 defense hardware startup building mass-produced, soldier-deployable autonomous interceptors that shoot down attacking drones for a fraction of the cost of the drones themselves. Founded by four Canadians with roots in the Canadian Infantry and hardware engineering, the company designs and manufactures counter-drone systems for Western and allied forces, aiming to give frontline soldiers an affordable answer to mass drone-swarm attacks.
Perseus Defense
Perseus Defense is a YC S25 aerospace and defense startup building low-cost, man-portable guided micro-missiles to shoot down small drones. Its Harpe interceptor targets Group 1 and Group 2 drones at a claimed cost of under $10,000 per shot - roughly a 20x reduction versus existing systems - closing the cost gap where a $500 drone can threaten multi-million-dollar assets. Founded by ex-NASA aerospace engineer Jason Cornelius and ex-Boeing autonomy lead Steve Messinger, the company is building an affordable, mass-producible 'Iron Dome for drones' for U.S. defense and homeland security customers.
Allen Control Systems
Allen Control Systems (ACS) is an Austin-based defense technology company building Bullfrog, an AI-powered autonomous robotic weapon station designed to detect, track and shoot down hostile drones. Founded in 2022 by three engineer-entrepreneurs, ACS uses passive machine vision and custom fire-control software to turn standard machine guns into precision counter-drone turrets, aiming to cut the cost-per-kill of a drone from expensive missiles down to a few dollars of ammunition. The company raised a $200M Series B in 2026 at a $2.2B valuation to scale manufacturing for the U.S. military and allied forces.
Swarmer
Swarmer builds combat-proven, hardware-agnostic autonomy software that lets a single operator command hundreds of drones - across air, sea and ground - as one coordinated swarm. Born out of the war in Ukraine and founded in 2023, its STYX, MINAS and TRIDENT products translate human objectives into autonomous action while keeping people in control of life-or-death decisions. The company's software has supported more than 100,000 real-world combat missions, raised a record $15M Series A, and went public on the Nasdaq in 2026 under the ticker SWMR.
ZeroMark, Inc.
ZeroMark is a New York-based defense technology company building an AI targeting layer that turns ordinary infantry weapons into precision counter-drone systems. Its flagship Apex is a rifle-mounted, software-defined fire control system that uses electro-optical cameras, LiDAR and machine-vision ballistics to physically adjust a soldier's aim in real time, letting a dismounted operator hit small, fast-moving drones without specialist training. Founded in 2022 by former U.S. Navy servicemember and ex-MongoDB executive Joel Anderson, ZeroMark has raised roughly $7M in seed funding led by Ground Up Ventures and Andreessen Horowitz, followed by a 2025 strategic round, and has demonstrated its system in a U.S. Marine Corps live-fire exercise.
Airspace Defense
Airspace Defense (formerly Airspace Systems) is a Silicon Valley company that secures the low-altitude airspace where drones increasingly operate. Its patented Airspace Spatial platform fuses Remote ID, RF and electronic sensing, radar and AI analytics to detect, identify and track unauthorized drones and their operators at city scale. Founded in 2015 by a team from Apple, Google and Cisco, the company serves public safety agencies, national defense and major enterprises, and its autonomous Interceptor drone is held in the Smithsonian National Air and Space Museum.
Guardian RF
Guardian RF builds low-cost, passive radiofrequency sensors that make low-altitude airspace observable in real time. Founded in 2024 by three Georgetown physics majors, the company deploys palm-sized 'Scout' sensors that detect the control signals drones and their operators emit, triangulating both across a mesh network. Its systems have been battle-tested on the front lines in Ukraine and are now fielded at Vandenberg Space Force Base and across U.S. airports and event venues, turning drone detections into structured, shareable intelligence.
Thor Dynamics
Thor Dynamics is a Palo Alto-based defense-tech startup building Laser Armor, an AI-powered directed-energy system that detects, tracks, and neutralizes hostile drones and drone swarms with a high-energy laser. Founded in 2024 by a team of MIT- and Wharton-trained operators and former U.S. Navy leadership, the company pairs up-to-20-kilowatt laser output with reinforcement-learning targeting and NVIDIA edge compute to deliver affordable, scalable counter-drone defense for critical infrastructure and the military.
General Radar Corp.
General Radar Corp. is a Menlo Park deep-tech company building high-resolution, software-defined phased-array (AESA) radar systems for aerospace, defense, wind energy, autonomy, and weather markets. Founded in 2016 by former NASA/JPL engineer Dmitry Turbiner, the company pairs a GaN AESA front-end with digital beam-forming and GPU supercomputing to deliver radars it says are dramatically higher resolution and roughly 20x cheaper than legacy aerospace radar - largely from commercial off-the-shelf parts. It raised a $22M Series A in 2022, bringing total funding to roughly $47.5M.
CHAOS Industries
CHAOS Industries is a Los Angeles defense technology company building Coherent Distributed Networks (CDN), software-defined sensing systems that detect aerial and missile threats faster and cheaper than traditional radar. Founded in 2022, it makes distributed radar products like Vanquish and Astria for counter-drone, border, and homeland defense. By late 2025 the company had raised over $1 billion and reached a roughly $4.5 billion valuation.
