But would that of still hastened up the designs of the XXI and other more advanced types of U-Boats?
It risks further dilution of the experienced crews which lowers effectiveness.
It gives a chance to train far more U-boat crews prior to the beginning of the war, actually.
This provides a stronger cadre, allows for more ocean-going Type VII and Type IX boats, and means that the SLoC are more completely covered in the early stages of the war prior to the massive buildup of escorts and development of more advanced ASW weapons. Except, instead of fielding an additional 50+ boats, they built two battleships that netted a single warship kill between the two of them (and that one pretty tired and poorly built).
The United States did just fine strangling Japan without the Electroboats, and Germany could have as succeeded against England without them as well. The Type XXI and Type XXIII are pretty toys, but not necessary for a German fleet that would win the war (or rather, a fleet that would have kept Germany from loosing the war).
And I am LOVING watching this mega-ship develop- but am picturing a single, statuesque B-36 Peacemaker flying high above the range of its SAMs and AAA carrying a single bomb that will ensure every man aboard her dies bald, toothless and nauseated within a week or so... even if the hull survives.
Ok people, if you want to continue this tangent do so here - and no flaming. I'm just as guilty of going off topic so my posts that were a part of this came along for the ride too.
