I noticed the KC-46 Pegasus ( Do Rolls Royce not own the name? ) west of Dublin yesterday, I didn`t realise they had actually completed some.
From what I have read there was some debate as to what spec they should have, which seemed odd as the Italian`s and Japanese already have a version,the KC-767
I think the US version is to have the B787 cockpit displays and an improved boom system, probably cost oodles more as well.
