TillOnAIR is an autonomous detect-to-defeat C-UAS system from ParaZero Technologies, developed as the perimeter-defense layer within the DefendAir family. A ground-based sensor array identifies and follows an incoming drone, while the mission-control unit launches a fast quadcopter interceptor and continuously directs it toward the live target track. The interceptor does not require GPS, an onboard seeker, a targeting camera, or ground beacons for the engagement. Once positioned above the hostile drone, it deploys a DefendAir Net Pod to physically capture the target, then returns for installation of another pod. This architecture enables operation against fiber-optic-controlled, pre-programmed, and autonomous drones whose command links cannot be disrupted through electronic warfare.
A single ground system can manage multiple interceptors, supporting responses to more than one incoming threat. Each detection unit provides a 100° field of view, with four units forming 360° coverage and a 50–100 m protective area around the defended asset. The approximately 15 kg system can be established in the field in about 20 minutes, making it suitable for expeditionary positions as well as permanent installations. Its defeat mechanism uses no explosive warhead and produces no fragmentation, while captured aircraft can remain largely intact for subsequent forensic or intelligence examination. Because the interceptor itself returns after an engagement, only the Net Pod is expended. TillOnAIR is intended for perimeter and tactical-force protection, including forward positions, command facilities, air-defense sites, government locations, and energy infrastructure.
