Military.com has a report of an exercise in which a Marine V-22 refueled a CG H-65 on the ground.
My first reaction, is that this is a good exercise for the Marines, but I had a hard time imagining how the Coast Guard might use this capability. There were times when we had to call on the Air Force Aerospace Rescue and Recovery Service to fly very long missions out to sea because Coast Guard helicopters did not have an aerial refueling capability, but this would not help us in those cases. On the other hand this might be useful in the Arctic where fuel stops can be few and far between. There aren’t many Marine assets in Alaska, but the Air Force might have a similar capability.
Thanks to Lee for bringing this to my attention.
