Next-Gen Aerial Retardant
FORTRESS FR-205 HV is our next-gen iteration on the FORTRESS FR-200 aerial liquid concentrate long-term retardant, with a low viscosity rating and high-visibility (HV) fluorescent coloring. FORTRESS FR-205 HV brings new features to the frontlines of firefighting, and further improves on the environmental and safety profile of its predecessor. FORTRESS FR-205 HV is currently undergoing qualification testing with the United States Forest Service (USFS).
FORTRESS FR-205 HV features our unique magnesium chloride formulation, which means that it's more effective, safer for the environment, and more durable than conventional, fertilizer-based retardants.
Currently undergoing qualification testing with USFS.
Designed for wet concentrate storage and wet base operations.
Engineered for stronger fire barriers and superior fire control. Qualified for use with large airtankers, Very Large Air Tankers (VLATs), Single Engine Air Tankers (SEATS), and helicopters.
Gum-thickened low viscosity for improved drop characteristics.
Provides higher visibility during the day and at night, and fades over time when exposed to sunlight.
Self-hydrating when humidity exceeds 35%, enabling better fuel coverage, more effective fire suppression, and extended durability.
Not a fertilizer, does not contribute to the growth of flammable vegetation or freshwater eutrophication, does not contain any biocides, and is significantly less toxic to fish.
Corrosion inhibitor package minimizes corrosion on steel, brass and aluminum, making it safe for use around steel utility infrastructure.
Fortress is dedicated to developing and producing an eco-sensitive, sustainable, and more efficacious fire-retardant alternative to combat wildfires in California, the United States, and around the world.
All retardant depicted in aerial drop images is Fortress FRS fire retardant.
