WireBird protects critical sites from drone swarm attacks with autonomous drones that perch, recharge, and relaunch from overhead powerlines. Enemy drones are becoming cheaper, faster, and easier to deploy at scale, creating a timing gap in today’s defense model. Ground-based systems are hard to scale, and interceptor drones only work if they are close enough, charged enough, and ready before the swarm arrives. WireBird turns existing overhead powerlines into forward recharge points for defense drones. This removes battery swaps, reduces range dependency, and enables persistent aerial sentries to stay on station near vulnerable sites. Our retrofit kit upgrades existing drones into field-persistent defense assets, enabling faster interception, longer endurance, and protection domes wherever powerlines exist.
