Re: Golden Age Resources: Superweapons of WW II
Considering the state Japanese forces were in by the time the first two I-400s became operational (AND the problems they had building and manning just about anything at that stage), I seriously doubt that they could have mustered the force for an undertaking like this. Let alone get it all the way to Panama - which was, let's be very clear, a heckuva long way from Japanese waters even at the height of their expansion.
Which is NOT saying, mind you, that higher-ups in Japan wouldn't have had a thought or two in this direction. As the war progressed, 'wishful thinking' seemed to play a greatly increased role in their operational planning.
