Germany invades Poland, overrunning it within weeks, followed by a declaration of war by France and Britain.
Despite the pleas of Donitz, however, instead of building U-boats, Hitler orders Raeder to continue on his massive surface fleet. Hitler decides the O-class battlecruisers will be continued.
All other surface ships (besides extra Panzerschiffle) of Plan Z will continue to be built:
How will the Western Allies adapt to a different Kreigsmarine? Will the Lion class battleships continue to be built? How will naval warfare in the Pacific fare, particularly with less development of anti submarine warfare? How many ships of Plan Z could have been built? Will the war have ended sooner? Could the Western Allies landed earlier, therefore allowing them to take over more of Europe?
What do you think?
