Re CC Post 425:
Just some additional information re the refueling/self-deployment ability question. The original Army plans for deployment to Europe involved a lot of UH-60’s and there was/is a limit to USAF transport space.
Therefore the Army requested a design for self deployment after the original production was started, and the result of that was the ESSS ( External Stores Support System ). ( Their thinking involved other possible uses of the ESSS “ wings ). The original configuration was two inboard 450 gallon tanks and two outboard 230 gallon tanks. Taking off at 24,500 lbs, they had enough fuel to fly from Newfoundland to the Azores.
