After a solicitation process that dragged on for almost two years, the U.S. Air Force has awarded the contract to build and install retardant delivery systems for up to seven of the seven HC-130H aircraft that are being transferred from the Coast Guard to the U.S. Forest Service.
The Coulson Group announced today that they received the contract. In one sense this is not unexpected because the company has installed and successfully operated two similar systems in C-130s — Tanker 131 and Tanker 132. In another sense, it is a surprise after the Government Accountability Office denied the company’s protest of the terms of the request for proposals in August of 2015.
“We are excited to have the opportunity to work with the United States Air Force to provide them with state of the art retardant aerial delivery systems (RADS) for their fleet of C-130s,” says Wayne Coulson, CEO and President of Coulson Aviation.
The 3,800-gallon retardant system will be gravity-based with retardant tanks that can be quickly removed, making it possible for the air tankers to also haul cargo or passengers.
One of the seven HC-130H aircraft began working out of McClellan Air Field near Sacramento last summer. Since it did not have a permanent retardant tank it borrowed one of the Forest Service’s eight Modular Airborne FireFighting Systems (MAFFS) that can be inserted into the cargo hold of a military C-130 to provide a surge capacity of air tankers during a time of heavy wildfire activity. The MAFFS pump the 3,000 gallons of retardant out of a pipe through the door using compressed air, rather than letting it drop out of the belly with the assistance of gravity as is done with conventional air tankers.
The Air Force is responsible for the retrofitting and performing the heavy maintenance that must be completed before the seven HC-130Hs are finally turned over to the USFS over the next three years. This contract is for the installation of one trial “kit”, one verification kit, and three production kits. There is an option for the installation of two additional production kits.
Coulson Aviation has 25 years of experience in aerial fire suppression and they operate both Type 1 helicopters and large fixed wing air tankers. Coulson is one of the few companies to hold multi-country aerial firefighting contracts, including Canada, the United States, and Australia.
