The WB100 - Drone Bucket Fire-fighting System for the FlyCart 100

The WB100 is a purpose-built water bucket for the FlyCart 100, designed to tackle fires in places ground crews struggle to reach — dense forests, steep mountainsides, and the upper floors of tall buildings. Instead of waiting on access roads or long hose runs, a drone carrying the WB100 can fly straight to the fire and discharge water precisely where it's needed.

The bucket itself is built around a collapsible skeletal frame wrapped in PVC waterproof fabric. It stands upright on its own for filling and standby, and it can also draw water directly from a lake, river, or reservoir on site — so crews aren't limited by how much water they can truck in. Under the hood, it combines a high-torque waterproof discharge pump, an ultrasonic level sensor, an independent remote control, night-use warning lights, and a sealed, weatherproof electrical system with a built-in battery. It runs on either a wired or wireless connection to the aircraft, whichever suits the mission.

Where It's Used

• Forest firefighting — reach blazes deep in tree cover that ground teams can't quickly access
• High-rise fire suppression — deliver water to upper floors without extending ladders or hoses
• Mountain fires — operate over terrain too steep or remote for vehicles
• Emergency & disaster support — general-purpose aerial water delivery for landslides, floods, and other emergency response scenarios
