Coulson Aviation USA has produced a video that demonstrates some of the capabilities of their 3,500-gallon Coulson RADS-XL Tank and the C-130Q which began flying under contract this fall, designated as Tanker 131. They shot the video at and near the San Bernardino air tanker base using cameras in their Sikorsky S76 helicopter, Firewatch 76. It shows the air tanker making down hill drops, which not every modern air tanker can accomplish very well.
The company bought the intellectual property for the RADS tank from Aero Union and in the last few months has been asked for price quotes for the tank system from a number of potential customers.
Britt Coulson told us:
Our plan is to manufacture and assemble the upper hopper and sell lower hopper subassembly kits where either we can complete the airframe install or another Lockheed Service Center can do the work.
Mr. Coulson said they have not finalized a price yet but it will be somewhere around $3.5 million installed. It would not surprise us if the U.S. Air Force will be calling for a quote, since they will be putting gravity tanks in the seven C-130Hs which will be transferred to the U.S. Forest Service after new wing boxes and fire retardant tanks are installed. The tank’s previous approval by the Interagency AirTanker Board will eliminate one very costly and time-consuming step in the process of converting an aircraft into an air tanker.
