ParaZero Technologies has launched TillOnAIR, an autonomous Counter-Unmanned Aerial System (C-UAS) engineered to deliver end-to-end perimeter defense against hostile drones.
The system expands the aerospace defense company’s DefendAir portfolio, shifting ParaZero from providing discrete interception technologies and platform integrations to manufacturing complete, proprietary detect-to-defeat platforms. Built for environments facing heavy electronic interference, the platform automates the entire engagement sequence, spanning initial threat identification, interceptor dispatch, guidance, net deployment, and interceptor recovery without human intervention.
A core technical differentiator of the architecture is the operational separation between ground-based guidance and the airborne interceptor. Ground-based mission control units detect, track, and guide the interceptor directly toward the target. Because guidance processing resides on the ground, the quadcopter interceptor operates without onboard GPS, homing seekers, cameras, or beacon receivers. This design yields a lightweight, cost-effective interceptor that remains functional in environments experiencing RF jamming or signal spoofing.
Interception relies on physical capture rather than electromagnetic disruption or high-explosive fragmentation. The reusable interceptor engages hostile drones from above using a DefendAir Net Pod, allowing it to neutralize threats that do not rely on standard radio-frequency links, such as autonomous, pre-programmed, or fiber-optic-guided drones. Following net deployment, the interceptor returns intact, requiring only the installation of a fresh Net Pod before re-entering service to maintain low recurring operating costs.
Weighing approximately 15kg, the hardware can be deployed in roughly 20 minutes to establish a 50-to-100-m modular, 360-degree protection bubble. A single ground unit can also direct multiple interceptors simultaneously to address coordinated multi-drone threats.
Ariel Alon, CEO of ParaZero, said, “TillOnAIR introduces a unique approach to autonomous drone defense: the intelligence and guidance remain on the ground, while a simple, reusable interceptor physically stops the threat. We have brought detection, guidance and interception together in one complete ParaZero system. This expands our role from providing the interception capability to delivering an entire autonomous defense solution, adding a new perimeter-protection layer to the DefendAir family.”
Within tactical operating environments, the system is designed to safeguard mobile military assets such as forward command posts, assembly areas, and field hospitals, while also servicing fixed installations including energy infrastructure, government facilities, radar sites, and air-defense batteries. The absence of explosive warheads also makes the platform suitable for civilian infrastructure, VIP protection, and public event security where falling fragmentation creates operational hazards.
The platform was unveiled at the AUSA Annual Meeting and Exposition in Washington, D.C., as well as the SIBAT Israeli National Defense Pavilion. ParaZero plans to host live operational demonstrations in Israel for military, government, and defense officials during November 2026, alongside an appearance at the UVID DroneTech conference in Tel Aviv on November 12, 2026, ahead of international field trials.
