DefendAir relies on a patented net launcher that captures and disables drones, thus reducing collateral damage and allowing safer use in urban or sensitive environments.
According to its developers, DefendAir is deployed in three configurations, which enables it to adapt to different operational scenarios. It can be launched using an interception drone, a stationary turret or a hand-held net gun, based on what the mission calls for and on the engagement range.
DefendAir has an effective range of 6.5 ft to 328 ft and employs nets that range in size from 9 square meters to 100 square meters. Further, the system can reportedly be integrated with existing detection, command-and-control and radio-frequency systems.
The interception drone iteration reportedly offers the longest reach, with an operational range of up to 1.24 miles. Additionally, it deploys nets that measure between 9 square meters and 25 square meters, and it operates autonomously using radar-based detection.
Meanwhile, the stationary turret configuration is intended for fixed-site defense, offering coverage up to 100 meters and supporting larger net sizes that range from 16 square meters to 100 square meters. This iteration also operates autonomously and features radar connectivity along with optical detection and tracking.
Last, the hand-held net gun, which is manually operated, is intended for close-range engagements, with a range of up to 35 meters and net sizes that range from 9 square meters to 25 square meters.
