Guardian RF

What it does

The 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 established multiple initiatives to counter the rapid proliferation of uncrewed aerial systems. The Joint Counter-small UAS Office (JCO) coordinates policy and acquisition across services. The Base Defense Cross-Functional Team enables persistent perimeter security for CONUS and OCONUS installations. Falcon Peak, Red Sands, and related exercises are accelerating deployment of counter-UAS technologies in complex environments. This threat is no longer exclusive to military operations overseas. It now directly targets the U.S. homeland. In 2025, an executive order designated the protection of American airspace sovereignty a national priority, recognizing that uncrewed systems present both surveillance and kinetic risks within the United States. That same year, a domestic extremist plotted to destroy a Tennessee power substation using a drone rigged with C-4 explosives—a plan disrupted by undercover federal agents. In July 2025, an unauthorized drone collided with a rescue helicopter during disaster response operations in Kerr County, Texas, forcing an emergency landing and halting flood relief efforts. These are not isolated incidents—they reflect a broader shift in drone-enabled threats against homeland infrastructure and public safety. Guardian RF builds passive, radiofrequency-based drone detection systems for force protection and critical infrastructure defense inside the United States. Our systems are fielded under an AFWERX Direct-to-Phase-II SBIR with the 30th Secur
