Gents,
I make no claims on which is the better product. I freely admit to not being qualified to offer such an opinion.
Keeping the US industial base is a national interest however. Regardless of NG teaming with EADS, and some (or even most) of the work being done in Alabama, the net effect would/will be a loss of US capability.
Whether that's inevitable or not is a separate issue.
How much moaning do you see here about the F-35 and/or other primarily US-based platforms being purchased, in cooperation and with much input from, other users - RAF/FAA/RAAF, etc? How the loss of sovereign manufacturing capabilty is a national tragedy?
I'd prefer to avoid that situation for the US.
