Uh, I thought the B-2 was built by Northrop Grumman. Was Boeing a major subcontractor was it?
The B-2 was designed and built by Northrop Grumman, Vought Aircraft and Boeing. Boeing was responsible for building part of the wings and the fuselage/wing root area.
The 748s role is to fill a seating capacity gap between the very popular 773 (~350 seats) and the all new A380 (+550 seats). I agree that many airlines currently using the 744s will be likely customers for the 748 and if the comparative fuel savings per passenger are realised (the claim is 14% per vs A380), the 748 could be a big seller. Those fuel savings are,
but of course,
disputed by Airbus and with the EIS of the extended A380, the efficiency difference will lessen or even reverse.
Meanwhile there is nothing like the A380 and likely won't be anything close to her anytime soon. Airbus has the super jumbo market all to itself.
