~~Yes, and the OP article is talking about tankers going across the Atlantic. So these are two separate things. (Maybe related things, but neither article connects the two)
I personally found no source relating then, but I may not know what to search for.~~
Edit: I see now that the OP did list those as airbase where tankers landed after crossing the Atlantic.
Maybe https://briarproject.org/how-it-works/ as an alternative
