Aerial Retardant
FORTRESS FR-200 is our first generation aerial liquid concentrate long-term retardant, with a low viscosity rating and fugitive coloring. FORTRESS FR-200 has successfully completed all of the required US Forest Service Laboratory tests for fire retardancy effectiveness, toxicity, anti-corrosion, stability, and viscosity. FORTRESS FR-200 has also passed the operational field evaluation (OFE) and is fully qualified for use.
FORTRESS FR-200 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.
Exceeded performance standards on every official USFS lab test.
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.
Visible coloring 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.
