Coulson Aviation Launches CFR HALO Fire Retardant

Coulson Aviation introduced a new long-term fire retardant, CFR HALO, on July 29, 2026, designed specifically to integrate with modern aerial firefighting delivery systems. Developed by the company’s research division, Coulson EmberWorks, the formulation aims to improve drop cohesion and reduce airborne drift compared to legacy retardants.

In a press release issued from its Thermal, California base, the company stated that CFR HALO addresses a growing disparity between advanced airtanker technology and older chemical formulations. The product is currently undergoing formal external qualification testing with the United States Department of Agriculture (USDA) Forest Service and the Centre d’Essais et de Recherche de l’Entente Valabre (CEREN) in Europe.

Engineering for modern airtankers

The development of CFR HALO focused on optimizing viscosity and flow characteristics to match the capabilities of contemporary precision delivery systems. The company leveraged four decades of operational experience to engineer the product. In 2026 alone, Coulson Aviation’s fixed-wing and rotary-wing fleet delivered 10 million gallons of water and wildfire suppressant globally.

Britt Coulson, President and Chief Operating Officer of Coulson Aviation, highlighted the operational disconnect driving the product’s development.

“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.”

Qualification and future integration

The current testing phase aims to place CFR HALO on the Qualified Products List (QPL) in the United States and France. These qualification programs will serve as a technical foundation for future agency acceptance in Australia and key South American markets.

Operationally, the retardant is engineered to integrate with existing mixing, loading, and application infrastructure. This ensures agencies will not need to replace established delivery systems to utilize the new chemistry.

The Coulson EmberWorks division

CFR HALO represents the inaugural product from Coulson EmberWorks, the company’s dedicated research and development division. Beyond chemical retardants, the division is also developing intelligent sensing and mission systems for future release.

AirPro News analysis

The introduction of CFR HALO marks a notable vertical integration step for Coulson Aviation. By expanding from aircraft operation and modification into chemical retardant manufacturing, we see the company positioning itself to control more of the aerial firefighting supply chain. If CFR HALO secures USDA and CEREN qualification, it could disrupt a retardant market historically dominated by a small number of specialized chemical suppliers. This move also allows the operator to tailor suppressant characteristics directly to the performance profiles of modern converted airtanker fleets.
