The type II was infact based off a WWI boat known as th UB type. It had some similarities, but was inferior to the type II. The type VII, the darling of the Kriegsmarine and it seems this forum, is a direct descendant of a WWI boat as well. I think it was the UC class. But the WWI version was also inferior.
Funny enough, the first fleet boats for the US were based off and derived from a WWI boat taken from the Germans at the end of the war.
