Coulson Aviation USA expands C-130H airtanker fleet

Coulson Aviation has announced the expansion of its C-130H Hercules fleet to 10 aircraft for aerial firefighting, following the acquisition of four aircraft from the New Zealand Defence Force.

The aircraft will be relocated to Coulson’s base in Thermal, California, where they will undergo a full conversion and modernization process. Each will be equipped with Coulson’s proprietary RADS-XXL tank system, enabling precision drops of up to 4,000gal. Once converted, the aircraft will expand Coulson’s global response capabilities, supporting firefighting missions worldwide.

Britton Coulson, President and Chief Operating Officer of Coulson Aviation USA, commented: “These aircraft continue to enhance our ability to respond rapidly and effectively to wildfires around the world – saving lives, protecting communities, and safeguarding critical natural and economic resources.”

Coulson Aviation will begin conversions later this year in close coordination with the Federal Aviation Administration (FAA). As part of the company’s vertically integrated approach – spanning aircraft acquisition, engineering, modification, operations, and maintenance – the entire process will be completed in-house. This model allows for rapid deployment and tailored solutions to meet the evolving demands of wildfire suppression around the globe.

“We have all observed the trend of increasingly intense and destructive fires over the past few years, beginning with Lahaina, Maui, in 2023, followed by Malibu, California, in 2024/25. On days marked by extreme fire behavior, it’s the large assets like the C-130s and CH-47s that can truly make a difference,” said Coulson.

The recently acquired C-130Hs, previously operated by the Royal New Zealand Air Force, have a distinguished operational history, with missions ranging from Antarctica to Afghanistan. These aircraft will now take on a new role, supporting efforts to protect communities, infrastructure, and natural resources from the increasing threat of wildfires.
