Quick Charge

Thanks to it’s large bottom aperture, the FLORY 26 helicopter bucket can achieve a full charge or discharge in just 3 seconds.

Fire Retardant

The helicopter bucket is fitted with a system of adding fire-retardant foams mid-flight, increasing extinguishing efficiency by up to 300%.

Rescue Basket

In an emergency, the FLORY 26 helicopter bucket doubles as a rescue basket, capable of taking 2-3 people away from the fire.

Wide Discharge

The high dispersion coefficient of 0.9 translates into 13 m of water dispersal width, making even the smallest targets unmissable.

Corrosion Resistant

The helicopter bucket is made of industrial-grade AISI 316L stainless steel that boasts incredible corrosion resistance.

Water Delivery

FLORY 26 is equipped with a release valve, enabling water delivery for ground-based fire crews.


Flotation devices are installed to the FLORY 26 monsoon bucket, allowing it to float on the water surface while released.

Multiple Discharges

The water flow can be closed near-instantaneously, allowing you to extinguish multiple separate packs of fire with a single charge of the monsoon bucket.


The monsoon bucket doesn’t tilt back or disappear from the operator’s sight, allowing the pilot to fly over the fire affected zones at high speeds.
