By the way. the 100ARW at Mildenhall aren’t exclusive to the U2 at all, they will service all kinds of trade, often not even US. They’ll go and park themselves in a racetrack pattern over the North Sea, off Cornwall, or over the Med and wait for the fast jets to show up. There is a website ‘Banter Ops’ that I used to have a login for where you could see what was coming and going from Mildenhall and Lakenheath. Often you’d see a tanker, or several, launch from Mildenhall and soon after a bunch of F15s from Lakenheath, they’d be calling something like RANGER or MATRIX, whatever, you could often tell from the jets callsigns which ones the tankers were on their way to service.
And there are other active units at Mildenhall, the 101SOS I believe with their Herks and H53s (soon to be Ospreys) and the SRW boys who have their Rivet Joints (RC135s) to play with.
In the days of the SR71 Blackbird, they used a unique fuel which only the KC135Q tankers were able to carry. You always knew when there was a Blackbird about, the Q’s would all launch about 3 hours beforehand.
Fascinating stuff ….. (or is just me ?)
