Thread creep off the ownership topic, but isn't the 'Voyager' the 1st new tanker a/c to ever be delivered to the RAF?
The Valiant's that I played with on 214, and the Victors that were rushed into the role when the Valiant's got their metal fatigue problems were 'field upgrades' from bombers, and of course the Tristars and VC-10 weren't even new airframes when the RAF got them. They were all 'tour ex' from civilian airlines.
I appreciate that the Voyager is a modified A-330, but it was modified on the drawing board and built as a Tanker not as an afterthought.
