Coulson Aviation has received a contract from the U.S. Air Force to install retardant delivery systems on the seven HC-130H aircraft that will be operated by the California Department of Forestry and Fire Protection (CAL FIRE). Coulson teamed with Lockheed Martin who will install the tanks at Lockheed’s facility in Greenville, SC.

The Air Force began the contracting process in 2014,  awarded a contract to Coulson in 2016, and cancelled it in 2017. But it was readvertised March 9, 2019 and awarded again to Coulson last month.

Coulson has been installing their version of a 3,500-gallon gravity-powered internal RADS retardant system in C-130Q and C-130H aircraft since at least 2013. It can be installed or removed in a few hours after the modifications are made to the plane.

On December 27, 2013 President Obama signed the 2014 National Defense Authorization Act which directed the Coast Guard to transfer seven HC-130H aircraft to the U.S. Forest Service. The legislation also directed that the Air Force spend up to $130 million to perform needed routine and heavy maintenance on the aircraft and to convert them into air tankers.

After the Forest Service lost interest in the HC-130H aircraft in 2018, Congress passed legislation to transfer them to CAL FIRE. Since then they have been waiting for the retardant systems to be installed and the maintenance and other conversion tasks to be completed, which is expected to take until 2021. Most of them needed center wing box replacements, which in 2011 cost $6.7 million and takes about 10 months. CAL FIRE has been operating one without a retardant tank, Tanker 118, for several months to train flight crews.

In November Coulson bought five C-130H transport planes from the Norwegian Defense Materiel Agency (NDMA) and will convert them into firefighting air tankers. The formal takeover is planned for the end of this year or early in 2020.

Thanks and a tip of the hat go out to Brett and Kevin. Typos or errors, report them HERE.
