Hmmm...in-flight refuelling from the deck of an aircraft carrier (of sorts).
Very clever, even if, as cyclic mentioned, a net increase in quantity aboard might take some time.
But, why would anyone want/need to do that? Why not land on deck, cup of coffee while they fill 'er up, go away again. Or refuel on deck with the rotor turning? Or is that not possible? Is a Sea King too big for the deck? My limited experience of 6 months as an embarked troop in the previous HMS Bulwark (Ahhh.... the Wessex) does not provide me with any answers.
Edit: Sorry, Stilton got in while I was composing!
Edit 2: just looked at the pics of Sea kings on the deck! Scrub the "too big" then.
