And it’s likely that the KC-45 won’t be using the CF6-80 variant now used, but likely a modified GENx engine. This will lower fuel burn, which improves the range over the current A330-200F.

But wouldn't that increase the burden on the very busy GENx line? Perhaps it could use an engine very similar to the bleed air version developed for the 747-800.

Thanks for the tech info. Post #48 really tells the story.
