Elbit Systems completed a successful field demonstration of its new Hydrop aerial firefighting system that enables retardant drops from much higher altitudes in day or night conditions. Hydrop uses precision-directed liquid pellets, enabling drops from as high as 500 feet to 2,000 feet agl, considerably higher than the typical 100- to 120-foot agl altitude required for the conventional liquid cascade method in use since the 1950s.

During Hydrop demonstration flights, drop aircraft launched 1.6 tons of 140-gram liquid pellets in a computed ballistic trajectory, achieving a precise hit with saturation of one to two liters per square meter. Hydrop integrates fighter aircraft avionics—including a ballistic computer, command and control (C2), and advanced display systems—together with biodegradable liquid pellets stored in a specially designed airborne dispenser.
