A teraz niemiecki obrońca konwojów po poprawkach.
Nie będę ukrywał, że uwagi De Villarsa były bezcenne w procesie ulepszania "projektu".

Głównymi błędami poprzedniej wersji były:
1. współczynnik pełnotliwości na poziomie 0,417
2. współczynnik wytrzymałości 0,50 przy wymaganym minimum na poziomie 1,0.
Dlatego wyporność standardowa była na poziomie niecałych 12 200 ton.
