Invading Norway will be a hell of a lot harder with less destroyers, the BV's can't carry the men in enough quantities.
Problem is the BV 222 only got operational by September 1940 or really december post fall of France... according to the wiki you posted!!!
An effort into a real four engine recce/bomber instead of the FW200 which was a civvie airliner pressed into service.
Other persuits of operating small flying boats by tenders at sea had proven not worth the effort and the US opted out of the big Mars.
the similar sized DO-X had operated in the 1920s, the concept and technology were proven only a decision made to pursue building them.
only used the Wiking as an example of size, design, etc. could just as easily have named a thread after Dornier DO-214
http://en.wikipedia.org/wiki/Dornier_Do_214 circa the same period (and they were the builder of the DO-X)
my thinking the FW-200 Condor was a clever use of existing aircraft, although they needed to press the JU-290 into service earlier as a successor.
(forget the HE-177 and use more powerful engines on HE-111 for a fast variant?)
do not see the comparison with whether the U.S. built flying boats or not, we had access to best ports and airfields in the world. AND ability to produce capital ships in numbers and throughout the war, Germany had none of those things.
destroyers for Norway campaign would not change, sorry if I was unclear, I proposed canceling the 1936A class - onward ( Z23 - onward, the ones given numerical designations) those were not launched 1940.
not sure if destroyers were best choice for Narvik anyway though? if 20 Wikings were available that would be nearly the same number carried by OTL flotilla (1,840 vs. 1,900.)
could have kept the shorter range destroyers elsewhere and sent the Emden, Bremse, and Grille (all could have laid mines) to Narvik along with dozen or so BV-222s.
