Digging deep into memory, there is a kit you can put on any USAF tanker (sounds like "mippers" though I forget the actual acronym) that renders either boom or basket method viable. Good for joint ops. (EDIT: Multiple Point Refuelling System, MPRS, under wing kit that allows a boom equipped tanker to also refuel drogue/probe equipped aircraft).
EDIT:
Hmm, interesting to note that most KC-135's have the drogue mod/kit equipped. Or maybe you have to make that decision before take off. (Why can't I remember any of this? Old age?)
