Coulson Aviation Introduces CFR HALO, a Long-Term Fire Retardant Engineered for Modern Aerial Firefighting

Coulson Aviation has introduced CFR HALO, a next-generation long-term fire retardant engineered specifically for modern aircraft, tank systems and wildfire missions. It is designed with mission-optimized viscosity and flow characteristics to improve drop cohesion, reduce airborne drift, and support more accurate placement within the intended target area. CFR HALO is currently advancing through independent qualification programs with CEREN in France and the USDA Forest Service for inclusion on the Qualified Products List (QPL). These programs will evaluate its performance, environmental profile, and operational suitability. Business Wire

Together, these programs will independently evaluate CFR HALO’s performance, environmental profile, and operational suitability through two of the world’s leading aerial firefighting qualification systems, building a technical foundation for agency acceptance in Australia and key South American markets.

“Wildfires have changed. The aircraft have changed. The retardant hasn’t kept up,” said Britt Coulson, President and COO of Coulson Aviation. “Many legacy formulations trace their origins to an era before today’s airtankers and precision delivery systems. We cannot keep fighting today’s fires with chemistry designed for yesterday’s aircraft. As operators, we had to step in and build what the industry needs next. CFR HALO is engineered for modern airtankers, with environmental performance built in from the start and a formulation designed to keep more of each load where firefighters need it.”

CFR HALO uses mission-optimized viscosity and flow characteristics designed to improve drop cohesion, reduce airborne drift, and support more accurate placement within the intended target area. The formulation can be optimized for different aircraft, terrain, weather conditions, and mission requirements while maintaining the long-term fire-retarding performance agencies depend on.

CFR HALO is also designed to integrate with existing retardant mixing, loading and application infrastructure without requiring agencies to replace established delivery systems or materially change operating procedures.

Article content

CFR HALO is grounded in Coulson’s direct operational experience. Over four decades, the company has seen the growing scale and intensity of wildfire response firsthand. In 2026 alone, Coulson’s fixed-wing and rotary-wing fleet has already delivered more than 10 million gallons of water and wildfire suppressant to fires worldwide.
