Coulson’s tank for their C-130Q
Coulson Aviation is putting the finishing touches on the 3,500-gallon retardant tank for their C-130Q, and they expect to roll it into the aircraft soon. Yes, it has wheels. Britt Coulson told Wildfire Today that they can install or remove it within 30 minutes. With or without the tank the air tanker can be pressurized. Without the tank, the C-130Q could be used for hauling cargo, or even smokejumpers, I suppose, if it were approved as a jumper platform.
Last week we posted an article, with photos, about the work the company is performing on the aircraft in a hangar in San Bernardino, California.
According to Mr. Coulson, the company bought from Aero Union “all the rights, engineering, and the drawings. We re-drew everything in Solidworks and re-designed the tank then manufactured it.” They are working with the USFS on the requirements for tests that involve dropping retardant into a grid of cups on the ground.
Use a similar tank for the C-27J?
Mr. Coulson said they are very interested in building tanks for the C-27J (an aircraft that the USFS may inherit from the Air Force) based on the same design, but scaled down to hold less retardant. He said the company responded to the U.S. Forest Service’s Request for Information posted in August to provide tanks for the aircraft, but the agency has not solicited for actual contract proposals yet. He believes the C-27J could carry somewhere between 2,500 and 3,000 gallons in an internal gravity-fed tank. Not all knowledgeable aviation folks we have talked with are optimistic that it could carry that much of a load. We have heard 1,800 gallons mentioned, and my own estimate is 1,800 to 2,300, but I am no expert.
(UPDATE, May 20, 2013: It was pointed out to us that converting the military version of the C-27J into a civilian air tanker would result in thousands of pounds of hardware being removed, perhaps with 2,000 to 4,000 pounds of weight savings. This could increase the retardant capacity by as much as 450 gallons, raising our estimate of the tank size to 2,000 to 2,650 gallons. This assumes an internal, gravity-fed tank system. A pressurized design, like the military MAFFS, would have a much lower capacity, requiring tanks for compressed air, additional valves and piping, and an air compressor.)
The Air Force has decided they don’t want any of their five-year-old C-27Js. You have to wonder why an agency would want to give away hundreds of millions of dollars worth of almost-new aircraft.
Tom Harbour, the U.S. Forest Service National Director of Fire and Aviation Management, was quoted in the Missoulian Tuesday on the subject of the C-27J:
“We are still working with the Department of Defense to see if we can get up to seven C-27J Spartans,” Harbour said. “If we acquire those platforms, we would modify them so we could use them as a medium air tanker. They’re not the size that is going to be able to carry type 1, large air tanker-capacity tanks, but we think they’re a very capable platform.” The Spartan is an Italian-made turboprop-powered cargo plane. The U.S. Air Force has offered to transfer up to 14 of the planes free to the Forest Service. Harbour said the plane is capable of carrying smokejumpers, but has only had preliminary testing as a retardant bomber.
If the USFS does procure and convert the C-27Js into air tankers, they may choose to pay contractors to fly and maintain them, similar to the CAL FIRE model for their 23 S-2T air tankers. CAL FIRE’s current support contractors are DynCorp and Logistics Specialties Incorporated. DynCorp provides air tanker and airtactical plane pilot services, and all aircraft maintenance services. (All CAL FIRE helicopters are flown by CAL FIRE pilots, but maintained by DynCorp.) LSI provides procurement and parts management services.
Fire Aviation has learned that some USFS aviation personnel have talked informally with DynCorp about a government-owned, contractor-operated program. According to the Missoulian article, Neptune would also be interested in bidding on a contract to provide these services.
Is the Air Force buying more C-27Js?
And just to confuse the issue further, when I was searching FedBizOpps.gov for the USFS Request for Information about the C-27J retardant tanks, the search results included a Sources Sought Synopsis survey placed there by the Air Force May 10, 2013. The agency is looking for companies that can manufacture more C-27Js. While the military says they don’t want the ones they have, and are giving those away and saying good riddance, they are considering buying more. Their reasoning is, they are….
…contemplating procurement of C-27J aircraft, in accordance with Congressional language that states “The secretary of the Air Force shall obligate and expend funds previously appropriated for the procurement of C-27J Spartan aircraft for the purposes for which such funds were originally appropriated.”
Here’s an idea.
Instead of buying more C-27Js at $53 million each, contemplate instead, if it is economically feasible, designing and building some purpose-built air tankers to enhance our homeland security.
