Waterbomber

nounStandard termAviation

A fixed-wing aircraft or helicopter designed to drop large payloads of water or fire retardant on wildfires.

A specialized aircraft used in aerial firefighting to drop massive loads of water, foam, or chemical retardants directly onto wildfires. These machines range from modified military bombers and commercial airliners to purpose-built amphibious flying boats that scoop water from lakes while skimming the surface. Pilots must fly heavy, fluid-filled airframes at extremely low altitudes through dense smoke and severe thermal turbulence to hit precise drop zones.

Insider tip

Flying a waterbomber requires managing massive, sudden shifts in the aircraft's center of gravity the exact moment thousands of gallons of fluid are released.
