There are a few of these operated by a NATO multi-national squadron: prominent NATO markings + Luxembourg registrations and national markings.
They often do appear on https://globe.adsbexchange.com (FR24 with knobs on but no time re-run facility), identified as EC3F. Aircraft seen occasionally going into and out of Mildenhall UK include LX-N90448 and LX-N90446.
Engines and pylons seem to be the old 707 J57/JT3C fit rather than the big fans of the latter day KC-135s.
Despite this they are built late 1970/early 80s, rather than the 1957-63 of the KC-135s that, re-engined, are trucking fuel all over Europe and from the USA today.
